Compiling a national register of babies born with anophthalmia/microphthalmia in England 1988-94. (1/86)
AIM: To describe the prevalence of anophthalmia/microphthalmia in babies born in England 1988-94, as well as their overall survival, and the incidence of associated eye and non-eye malformations; to determine the usefulness of different sources of medical and health service information for establishing a retrospective register of anophthalmia/microphthalmia. METHODS: Multiple sources for initial (retrospective) case ascertainment were surveyed, followed by questionnaires to clinicians to establish severity, associated malformations, and aetiology for England, 1988-94. The population surveyed was all births in England for this time period (4,570,350 births). Cases included live births, stillbirths, or terminations after prenatal diagnosis of congenital anomaly, with anophthalmia/microphthalmia, with or without other malformations and syndromes. Trisomy 13 was subsequently excluded. RESULTS: The proportion of cases notified by any one information source was not more than 26% (Office for National Statistics Register 22%, paediatricians 26%, district sources 25%). Sixty nine per cent of cases (51% of severe cases) were notified by only one source. A total of 449 cases were reported, prevalence 1.0 per 10,000 births. The prevalence was stable over time, although the proportion notified by clinicians rose in more recent years. Thirty four per cent of affected babies had mild microphthalmia. Of those with severe anophthalmia/microphthalmia, 51% were bilateral, other eye malformations were present in 72%, non-eye malformations in 65%, and a "known aetiology" was attributed in 22%. Three quarters of those severely affected survived infancy. CONCLUSIONS: Despite high response rates from the sources of information contacted, the lack of duplication between sources indicates the difficulties of retrospective ascertainment and the need for multiple sources when establishing a register. Anophthalmos/microphthalmos is usually associated with other malformations. Most cases are of unknown aetiology. (+info)Anophthalmia in litters of female rats treated with the food-derived carcinogen, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine. (2/86)
Anophthalmia in litters of pregnant rats treated with 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), a food-derived carcinogen, was incidentally encountered in a risk-assessment study with 2-generation exposure to PhIP. Female Fischer 344 animals were given 200 ppm PhIP in the diet for 4 wk before mating with nontreated males and also during gestation and lactation periods. Mean numbers of newborn rats per litter in control and PhIP-treated groups were 7.9 +/- 2.9 and 7.1 +/- 1.6 in trial 1 and 8.3 +/- 1.9 and 6.1 +/- 2.4 in trial 2. Among 49 (trial 1) and 63 (trial 2) offspring from PhIP-treated dams, 9 (18.4%) and 32 (50.8%) demonstrated anophthalmia, and 1 (2.0%) and 8 (12.7%) demonstrated hydrocephaly. Five of 7 (71.4%) and 13 of 14 (92.9%) dams delivered pups with malformations in trials 1 and 2, respectively. Also, in a previous study that was carried out with the same protocol and that used the Sprague-Dawley strain of rats, anophthalmia and hydrocephaly were observed in 2 and 1 out of 175 pups, respectively, from 100 ppm PhIP-treated dams. No congenital malformations were found in control groups of the same size in either experiment. In addition to having been previously identified as a cause of carcinogenic activity, our findings suggest that PhIP is capable of causing anophthalmia in rats when administered during the gestational period. (+info)Anophthalmia and retinal degeneration associated with stenosis of the optic foramen in Fischer 344 rats. (3/86)
Bilateral anophthalmia was discovered in a male rat (No. 1) and unilateral anophthalmia was found in the left eye of two female rats (Nos. 2 and 3) derived from a Fischer 344 inbred colony. One male rat (No. 4), a littermate of No. 3, had externally normal eyes, but his left eye had severe retinal atrophy, which was detected by ophthalmoscopy. The eyelids in both eyes of No. 1 and in the left eyes of Nos. 2 and 3 were present. Radiography of the skull revealed small optic foramina on both sides of No. 1 and on the affected side of Nos. 2, 3, and 4. Histologically, both globes and optic nerves (ONs) of No. 1 and the left globe and ONs of Nos. 2 and 3 were completely missing. Diffuse retinal degeneration in the left globe and axonal degeneration in the left ON and the right optic tract were observed in No. 4. Dysplasia of the sphenoid bone associated with stenosis of the optic foramen was detected on the affected side of all rats. Thus, ON aplasia in anophthalmic rats and atrophic ON in a rat with retinal degeneration seem to be closely related to stenosis of the optic foramen. (+info)Total retinal degeneration in apparent anophthalmos of the Syrian hamster. (4/86)
Anophthalmia in the Syrian hamster was found to result from an extensive degeneration of retinal tissue and tissues derived from the retina. Eyes of affected animals were normal at the twelfth day of gestation (the average gestation period in the Syrian hamster is 16 days). However, the retina of these eyes showed rapid and extensive degeneration during the first two weeks after birth. In adults, the sclera-choroid complex was the only prominent structure of the original eye, with an occasional remnant of deteriorated lens. (+info)Spontaneous reversal of nystagmus in the dark. (5/86)
AIM: To report five children with horizontal jerk nystagmus in whom eye movement recordings in the dark revealed a spontaneous reversal in the direction of the nystagmus beat. Three patients were blind in one eye and were diagnosed as having a manifest latent nystagmus (MLN), and two patients had strabismus and congenital nystagmus (CN). METHODS: Eye movements were recorded using DC electro-oculography with simultaneous video recording, including infrared recording in total darkness. RESULTS: Four patients had decelerating velocity slow phase jerk nystagmus when recorded under natural lighting conditions; the fifth case had accelerating velocity and linear slow phase jerk nystagmus. Under absolute darkness, nystagmus reversed in direction of beat with a mixture of linear and decelerating velocity slow phase waveforms. One child with unilateral anophthalmos could wilfully reverse the beat direction of his nystagmus by trying to look with his blind eye in the light and dark. CONCLUSIONS: These observations support the theory that LN/MLN beat direction is determined by the "presumed" viewing eye and may be consciously controlled. The spontaneous reversal of beat direction in the dark suggests eye dominance is predetermined. Eye movement recordings identified mixed nystagmus waveforms indicating that CN (accelerating velocity slow phases) and LN/MLN (linear/decelerating velocity slow phases) coexist in these subjects. (+info)National study of microphthalmia, anophthalmia, and coloboma (MAC) in Scotland: investigation of genetic aetiology. (6/86)
We report an epidemiological and genetic study attempting complete ascertainment of subjects with microphthalmia, anophthalmia, and coloboma (MAC) born in Scotland during a 16 year period beginning on 1 January 1981. A total of 198 cases were confirmed giving a minimum live birth prevalence of 19 per 100 000. One hundred and twenty-two MAC cases (61.6%) from 115 different families were clinically examined and detailed pregnancy, medical, and family histories obtained. A simple, rational, and apparently robust classification of the eye phenotype was developed based on the presence or absence of a defect in closure of the optic (choroidal) fissure. A total of 85/122 (69.7%) of cases had optic fissure closure defects (OFCD), 12/122 (9.8%) had non-OFCD, and 25/122 (20.5%) had defects that were unclassifiable owing to the severity of the corneal or anterior chamber abnormality. Segregation analysis assuming single and multiple incomplete ascertainment, respectively, returned a sib recurrence risk of 6% and 10% in the whole group and 8.1% and 13.3% in the OFCD subgroup. Significant recurrence risks were found in both unilateral and bilateral disease. In four families, one parent had an OFCD, two of which were new diagnoses in asymptomatic subjects. All recurrences in first degree relatives occurred in the OFCD group with a single first cousin recurrence seen in the non-OFCD group. A total of 84/122 of the MAC cases were screened for mutations in the coding regions of PAX6, CHX10, and SIX3. No pathogenic mutations were identified in the OFCD cases. A single PAX6 homeodomain missense mutation was identified in a subject with partial aniridia that had been initially misclassified as coloboma. (+info)A case of growth hormone and gonadotropin deficiency associated with unilateral anophthalmia, microphallus, cryptorchidism, and mental retardation. (7/86)
We report a rare case of growth hormone and gonadotropin deficiency associated with dysmorphic features. A 16-year-old boy had left anophthalmia, microphallus, bilateral cryptorchidism, and mental retardation. His chromosomal karyotype was normal, 46, XY. Endocrinological studies revealed growth hormone and gonadotropin deficiency, attributed to hypothalamic dysfunction. Magnetic resonance imaging scan of the head showed a hypoplastic pituitary gland, decreased high intensity signals in the pituitary posterior lobe, absence of the left eye, and a hypoplastic left optic nerve with no abnormality of the pituitary stalk, corpus callosum, or septum pellucidum. Although not completely consistent with the features of septo-optic dysplasia (SOD), his condition was considered within the spectrum of SOD. Despite similarities to the Hesx1 knockout mouse, a model of human SOD, mutation analyses revealed no mutations or polymorphisms in coding regions of any exons or intron-exon boundaries of the HESX1 gene. Further genetic studies of this patient may improve understanding of molecular mechanisms involved in pituitary development. (+info)Delineation of an estimated 6.7 MB candidate interval for an anophthalmia gene at 3q26.33-q28 and description of the syndrome associated with visible chromosome deletions of this region. (8/86)
Anophthalmia or microphthalmia occur in approximately one in 10 children who have severe visual impairment. These eye malformations are often of unknown aetiology, but can be inherited in autosomal dominant, recessive or X-linked forms, and can also occur in association with specific chromosome abnormalities. Four children are described in the medical literature with microphthalmia or anophthalmia in association with chromosome rearrangements involving distal 3q, suggesting the presence of a micro/anophthalmia gene in this region. We have identified two further patients with micro/anophthalmia and chromosome rearrangements involving 3q26-->3q27 and identified a 6.7 MB common deleted region. Patient 1 had multiple abnormalities including bilateral anophthalmia, abnormalities of the first and second cranial nerves and partial absence of the corpus callosum. His karyotype was 46,XY,del(3)(q26.33q28). Patient 2 had right anophthalmia and left extreme microphthalmia. Her karyotype was 46,XX,del(3)(q26.33q28)t(3;7)(q28;q21.1). Both patients had intrauterine growth retardation (IUGR) and strikingly similar dysmorphic facies consisting of bossed forehead, downward-slanting palpebral fissures, grooved bridge of the nose, prominent low-set ears, small down-turned mouth and small mandible. We identified BAC clones mapping to distal 3q from the ENSEMBL and NCBI Entrez databases. These BAC clones were used as fluorescence in situ hybridisation (FISH) probes to identify the minimum deleted region common to both patients. This interval, between clones RPC11-134F2 and RPC11-132N15, was estimated to be 6.7 MB. We conclude that there is an anophthalmia locus within this interval. Candidate genes mapping to this region include Chordin and DVL3, a homologue of the Drosophila Dishevelled gene. (+info)Anophthalmos is a medical condition where an individual is born without one or both eyes. It is a congenital disorder, which means it is present at birth. In cases where only one eye is affected, it is called unilateral anophthalmos, and when both eyes are missing, it is referred to as bilateral anophthalmos.
Anophthalmos is different from microphthalmia, another congenital condition where the eye is present but abnormally small. In some cases, anophthalmos may be accompanied by other developmental anomalies or syndromes. The exact cause of anophthalmos is not always known, but it can be associated with genetic mutations or environmental factors that affect fetal development.
Individuals with anophthalmos require specialized medical care and management to ensure proper eye socket development, visual rehabilitation, and overall well-being. This may include the use of prosthetic eyes, orthoptic therapy, and other supportive measures.
An artificial eye, also known as a prosthetic eye, is a type of medical device that is used to replace a natural eye that has been removed or is not functional due to injury, disease, or congenital abnormalities. It is typically made of acrylic or glass and is custom-made to match the size, shape, and color of the patient's other eye as closely as possible.
The artificial eye is designed to fit over the eye socket and rest on the eyelids, allowing the person to have a more natural appearance and improve their ability to blink and close their eye. It does not restore vision, but it can help protect the eye socket and improve the patient's self-esteem and quality of life.
The process of fitting an artificial eye typically involves several appointments with an ocularist, who is a healthcare professional trained in the measurement, design, and fabrication of prosthetic eyes. The ocularist will take impressions of the eye socket, create a model, and then use that model to make the artificial eye. Once the artificial eye is made, the ocularist will fit it and make any necessary adjustments to ensure that it is comfortable and looks natural.
Microphthalmos is a medical condition where one or both eyes are abnormally small due to developmental anomalies in the eye. The size of the eye may vary from slightly smaller than normal to barely visible. This condition can occur in isolation or as part of a syndrome with other congenital abnormalities. It can also be associated with other ocular conditions such as cataracts, retinal disorders, and orbital defects. Depending on the severity, microphthalmos may lead to visual impairment or blindness.
Agenesis of the corpus callosum is a birth defect in which the corpus callosum, the part of the brain that connects the two hemispheres and allows them to communicate, fails to develop normally during fetal development. In cases of agenesis of the corpus callosum, the corpus callosum is partially or completely absent.
This condition can vary in severity and may be associated with other brain abnormalities. Some individuals with agenesis of the corpus callosum may have normal intelligence and few symptoms, while others may have intellectual disability, developmental delays, seizures, vision problems, and difficulties with movement and coordination. The exact cause of agenesis of the corpus callosum is not always known, but it can be caused by genetic factors or exposure to certain medications or environmental toxins during pregnancy.
The optic chiasm is a structure in the brain where the optic nerves from each eye meet and cross. This allows for the integration of visual information from both eyes into the brain's visual cortex, creating a single, combined image of the visual world. The optic chiasm plays an important role in the processing of visual information and helps to facilitate depth perception and other complex visual tasks. Damage to the optic chiasm can result in various visual field deficits, such as bitemporal hemianopsia, where there is a loss of vision in the outer halves (temporal fields) of both eyes' visual fields.
Craniofacial abnormalities refer to a group of birth defects that affect the development of the skull and face. These abnormalities can range from mild to severe and may involve differences in the shape and structure of the head, face, and jaws, as well as issues with the formation of facial features such as the eyes, nose, and mouth.
Craniofacial abnormalities can be caused by genetic factors, environmental influences, or a combination of both. Some common examples of craniofacial abnormalities include cleft lip and palate, craniosynostosis (premature fusion of the skull bones), and hemifacial microsomia (underdevelopment of one side of the face).
Treatment for craniofacial abnormalities may involve a team of healthcare professionals, including plastic surgeons, neurosurgeons, orthodontists, speech therapists, and other specialists. Treatment options may include surgery, bracing, therapy, and other interventions to help improve function and appearance.
The optic nerve, also known as the second cranial nerve, is the nerve that transmits visual information from the retina to the brain. It is composed of approximately one million nerve fibers that carry signals related to vision, such as light intensity and color, from the eye's photoreceptor cells (rods and cones) to the visual cortex in the brain. The optic nerve is responsible for carrying this visual information so that it can be processed and interpreted by the brain, allowing us to see and perceive our surroundings. Damage to the optic nerve can result in vision loss or impairment.
MedlinePlus is not a medical term, but rather a consumer health website that provides high-quality, accurate, and reliable health information, written in easy-to-understand language. It is produced by the U.S. National Library of Medicine, the world's largest medical library, and is widely recognized as a trusted source of health information.
MedlinePlus offers information on various health topics, including conditions, diseases, tests, treatments, and wellness. It also provides access to drug information, medical dictionary, and encyclopedia, as well as links to clinical trials, medical news, and patient organizations. The website is available in both English and Spanish and can be accessed for free.
A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.
For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.
It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.
I'm sorry for any confusion, but "Gross Domestic Product" (GDP) is an economic term, not a medical one. GDP is the total monetary or market value of all the finished goods and services produced within a country's borders in a specific time period. It serves as a comprehensive measure of a nation’s overall economic activity.

Genetics is the scientific study of genes, heredity, and variation in living organisms. It involves the analysis of how traits are passed from parents to offspring, the function of genes, and the way genetic information is transmitted and expressed within an organism's biological system. Genetics encompasses various subfields, including molecular genetics, population genetics, quantitative genetics, and genomics, which investigate gene structure, function, distribution, and evolution in different organisms. The knowledge gained from genetics research has significant implications for understanding human health and disease, as well as for developing medical treatments and interventions based on genetic information.
In medical terms, the foot is the part of the lower limb that is distal to the leg and below the ankle, extending from the tarsus to the toes. It is primarily responsible for supporting body weight and facilitating movement through push-off during walking or running. The foot is a complex structure made up of 26 bones, 33 joints, and numerous muscles, tendons, ligaments, and nerves that work together to provide stability, balance, and flexibility. It can be divided into three main parts: the hindfoot, which contains the talus and calcaneus (heel) bones; the midfoot, which includes the navicular, cuboid, and cuneiform bones; and the forefoot, which consists of the metatarsals and phalanges that form the toes.
PubMed is not a medical condition or term, but rather a biomedical literature search engine and database maintained by the National Center for Biotechnology Information (NCBI), a division of the U.S. National Library of Medicine (NLM). It provides access to life sciences literature, including journal articles in medicine, nursing, dentistry, veterinary medicine, health care systems, and preclinical sciences.
PubMed contains more than 30 million citations and abstracts from MEDLINE, life science journals, and online books. Many of the citations include links to full-text articles on publishers' websites or through NCBI's DocSumo service. Researchers, healthcare professionals, students, and the general public use PubMed to find relevant and reliable information in the biomedical literature for research, education, and patient care purposes.
I'm sorry for any confusion, but "Reptiles" is not a medical term. It is a term used in biology to describe a class of cold-blooded, scaly-skinned animals that include snakes, lizards, alligators, crocodiles, turtles, and tortoises. They are characterized by having lungs for breathing, laying eggs on land, and having a three-chambered heart. If you have any medical questions or terms, I'd be happy to help clarify those!
Tropicamide is a muscarinic antagonist, which is a type of drug that blocks the action of acetylcholine in the body. In particular, it blocks the muscarinic receptors found in the eye, which results in pupil dilation (mydriasis) and paralysis of the ciliary muscle (cycloplegia).
Tropicamide is commonly used in ophthalmology as a diagnostic aid during eye examinations. It is often instilled into the eye to dilate the pupil, which allows the eye care professional to more easily examine the back of the eye and assess conditions such as cataracts, glaucoma, or retinal disorders. The cycloplegic effect of tropicamide also helps to relax the accommodation reflex, making it easier to measure the refractive error of the eye and determine the appropriate prescription for eyeglasses or contact lenses.
It is important to note that tropicamide can cause temporary blurring of vision and sensitivity to light, so patients should be advised not to drive or operate heavy machinery until the effects of the medication have worn off.
Eye diseases are a range of conditions that affect the eye or visual system, causing damage to vision and, in some cases, leading to blindness. These diseases can be categorized into various types, including:
1. Refractive errors: These include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, which affect the way light is focused on the retina and can usually be corrected with glasses or contact lenses.
2. Cataracts: A clouding of the lens inside the eye that leads to blurry vision, glare, and decreased contrast sensitivity. Cataract surgery is the most common treatment for this condition.
3. Glaucoma: A group of diseases characterized by increased pressure in the eye, leading to damage to the optic nerve and potential blindness if left untreated. Treatment includes medications, laser therapy, or surgery.
4. Age-related macular degeneration (AMD): A progressive condition that affects the central part of the retina called the macula, causing blurry vision and, in advanced stages, loss of central vision. Treatment may include anti-VEGF injections, laser therapy, or nutritional supplements.
5. Diabetic retinopathy: A complication of diabetes that affects the blood vessels in the retina, leading to bleeding, leakage, and potential blindness if left untreated. Treatment includes laser therapy, anti-VEGF injections, or surgery.
6. Retinal detachment: A separation of the retina from its underlying tissue, which can lead to vision loss if not treated promptly with surgery.
7. Amblyopia (lazy eye): A condition where one eye does not develop normal vision, often due to a misalignment or refractive error in childhood. Treatment includes correcting the underlying problem and encouraging the use of the weaker eye through patching or other methods.
8. Strabismus (crossed eyes): A misalignment of the eyes that can lead to amblyopia if not treated promptly with surgery, glasses, or other methods.
9. Corneal diseases: Conditions that affect the transparent outer layer of the eye, such as keratoconus, Fuchs' dystrophy, and infectious keratitis, which can lead to vision loss if not treated promptly.
10. Uveitis: Inflammation of the middle layer of the eye, which can cause vision loss if not treated promptly with anti-inflammatory medications or surgery.
Mydriatics are medications that cause mydriasis, which is the dilation of the pupil. These drugs work by blocking the action of the muscarinic receptors in the iris, leading to relaxation of the circular muscle and constriction of the radial muscle, resulting in pupil dilation. Mydriatics are often used in eye examinations to facilitate examination of the interior structures of the eye. Commonly used mydriatic agents include tropicamide, phenylephrine, and cyclopentolate. It is important to note that mydriatics can have side effects such as blurred vision, photophobia, and accommodation difficulties, so patients should be advised accordingly.
The cornea is the clear, dome-shaped surface at the front of the eye. It plays a crucial role in focusing vision. The cornea protects the eye from harmful particles and microorganisms, and it also serves as a barrier against UV light. Its transparency allows light to pass through and get focused onto the retina. The cornea does not contain blood vessels, so it relies on tears and the fluid inside the eye (aqueous humor) for nutrition and oxygen. Any damage or disease that affects its clarity and shape can significantly impact vision and potentially lead to blindness if left untreated.
Eye abnormalities refer to any structural or functional anomalies that affect the eye or its surrounding tissues. These abnormalities can be present at birth (congenital) or acquired later in life due to various factors such as injury, disease, or aging. Some examples of eye abnormalities include:
1. Strabismus: Also known as crossed eyes, strabismus is a condition where the eyes are misaligned and point in different directions.
2. Nystagmus: This is an involuntary movement of the eyes that can be horizontal, vertical, or rotatory.
3. Cataracts: A cataract is a clouding of the lens inside the eye that can cause vision loss.
4. Glaucoma: This is a group of eye conditions that damage the optic nerve and can lead to vision loss.
5. Retinal disorders: These include conditions such as retinal detachment, macular degeneration, and diabetic retinopathy.
6. Corneal abnormalities: These include conditions such as keratoconus, corneal ulcers, and Fuchs' dystrophy.
7. Orbital abnormalities: These include conditions such as orbital tumors, thyroid eye disease, and Graves' ophthalmopathy.
8. Ptosis: This is a condition where the upper eyelid droops over the eye.
9. Color blindness: A condition where a person has difficulty distinguishing between certain colors.
10. Microphthalmia: A condition where one or both eyes are abnormally small.
These are just a few examples of eye abnormalities, and there are many others that can affect the eye and its functioning. If you suspect that you have an eye abnormality, it is important to consult with an ophthalmologist for proper diagnosis and treatment.
