Diffuse loss of sensitivity in early glaucoma. (1/64)
PURPOSE: To establish whether there is significant diffuse loss of sensitivity in a population of patients with early glaucoma. METHODS: The differential light sensitivities at the 10 most sensitive locations from within the central 24 degrees of program 30-2 of the Humphrey Field Analyzer (Humphrey Instruments, San Leandro, CA) were compared in 38 pairs of age-matched subjects, one of each pair with early primary open-angle glaucoma (POAG) and the other with normal eyes. All subjects had had experience with automated perimetry and had clear media, visual acuity of 20/25 or better, and one or fewer false-positive or false-negative responses to catch trials. RESULTS: The mean difference in age between the subjects with glaucoma and normal subjects was 29 days (P = 0.44, maximum 1.42 years). The mean paired difference in pupil size was 0.16 mm (P = 0.26), and visual acuity was higher in the glaucoma-affected subjects (P = 0.044). The 10 highest sensitivity measurements in the POAG-affected subjects were found to be lower by a median of between 1.0 and 2.0 dB than those in the normal pair members (0.0001Novel locus for autosomal recessive cone-rod dystrophy CORD8 mapping to chromosome 1q12-Q24. (2/64)
PURPOSE: To map the disease locus of a two-generation, consanguineous Pakistani family with autosomal recessive cone-rod dystrophy (arCRD). All affected individuals had night blindness, deterioration of central vision, photophobia, epiphora in bright light, and problems with color distinction. Fundoscopy revealed marked macular degeneration and attenuation of retinal vessels. Mild pigmentary changes were present in the periphery. METHODS: Genomic DNA was amplified across the polymorphic microsatellite poly-CA regions identified by markers. Alleles were assigned to individuals that allowed calculation of LOD scores using the Cyrillic (Cherwell Scientific, Oxford, UK) and MLINK (accessed from ftp://linkage. rockefeller.edu/softeware/linkage/) software programs. The cellular retinoic acid-binding protein 2 (CRABP2), cone transducin alpha-subunit (GNAT2), potassium inwardly rectifying channel, subfamily J, member 10 (KCNJ10), genes were analyzed by heteroduplex analysis and direct sequencing for mutations. RESULTS: A new locus for arCRD (CORD8) has been mapped to chromosome 1q12-q24. A maximum two-point LOD score of 4.22 was obtained with marker D1S2635 at recombination fraction of theta = 0.00. Two critical recombinations in the pedigree positioned this locus to a region flanked by markers D1S457 and D1S2681. A region of homozygosity was observed within the loci D1S442 and D1S2681, giving a probable critical disease interval of 21 cM. Mutation screening of the three candidate genes CRABP2, GNAT2, and KCNJ10 revealed no disease-associated mutations. CONCLUSIONS: The findings therefore suggest that this phenotype maps to a new locus and is due to an as yet uncharacterized gene within the 1q12-q24 chromosomal region. (+info)Sensory capacity of the royal college of surgeons rat. (3/64)
PURPOSE: To apply noninvasive tests for examining visual and other sensory functions of pigmented Royal College of Surgeons (RCS) rats compared with pigmented and albino control animals. METHODS: Rats aged 3 and 7 months were tested with a general neurologic examination that assessed visual, auditory, tactile, and whisker displacement responses. Photophobic responses and visual discrimination were also measured. RESULTS: Dystrophic RCS rats failed the visual presentation tests, even at 3 months of age, and showed diminished performance on tactile tests. Auditory and whisker displacement performances were normal. Albino rats also showed diminished performance on the visual test, particularly to stimuli presented in the upper visual field. Photophobic responses were diminished in the dystrophic RCS rats compared with the pigmented control animals. Albino animals showed heightened photophobia. The dystrophic rats failed to reach criterion levels of performance on the visual discrimination test even with gratings of 0.045 cyc/deg. CONCLUSIONS: The tests used discriminate deteriorated complex visual functions in RCS rats at ages when some simple reflexes can still be demonstrated. As such, they provide easily executed tests for screening for the effects of reparative treatments such as transplantation, administration of growth factors, and gene transfer technology. The integrity of whisker and auditory function are important when using tests requiring polysensory inputs. The somatosensory defect is surprising but may be useful in searching for the gene locus of the retinal disorder. The aberrations seen in the albino rats may be attributable to the effects of light damage and unfiltered light. (+info)Mutations in FOXC2 (MFH-1), a forkhead family transcription factor, are responsible for the hereditary lymphedema-distichiasis syndrome. (4/64)
Lymphedema-distichiasis (LD) is an autosomal dominant disorder that classically presents as lymphedema of the limbs, with variable age at onset, and double rows of eyelashes (distichiasis). Other complications may include cardiac defects, cleft palate, extradural cysts, and photophobia, suggesting a defect in a gene with pleiotrophic effects acting during development. We previously reported neonatal lymphedema, similar to that in Turner syndrome, associated with a t(Y;16)(q12;q24.3) translocation. A candidate gene was not found on the Y chromosome, and we directed our efforts toward the chromosome 16 breakpoint. Subsequently, a gene for LD was mapped, by linkage studies, to a 16-cM region at 16q24.3. By FISH, we determined that the translocation breakpoint was within this critical region and further narrowed the breakpoint to a 20-kb interval. Because the translocation did not appear to interrupt a gene, we considered candidate genes in the immediate region that might be inactivated by position effect. In two additional unrelated families with LD, we identified inactivating mutations-a nonsense mutation and a frameshift mutation-in the FOXC2 (MFH-1) gene. FOXC2 is a member of the forkhead/winged-helix family of transcription factors, whose members are involved in diverse developmental pathways. FOXC2 knockout mice display cardiovascular, craniofacial, and vertebral abnormalities similar to those seen in LD syndrome. Our findings show that FOXC2 haploinsufficiency results in LD. FOXC2 represents the second known gene to result in hereditary lymphedema, and LD is only the second hereditary disorder known to be caused by a mutation in a forkhead-family gene. (+info)Amniotic membrane transplantation for partial limbal stem cell deficiency. (5/64)
AIM: To examine the efficacy, safety, and long term outcomes of amniotic membrane transplantation for corneal surface reconstruction in cases of partial limbal stem cell deficiency. METHODS: 17 eyes of 15 patients with partial limbal stem cell deficiency underwent superficial keratectomy of the conjunctivalised corneal surface followed by amniotic membrane transplantation. Cases were followed up for at least a year. RESULTS: All eyes exhibited a stable, intact corneal epithelial surface after a mean follow up period of 25.8 months with no eyes developing recurrent erosion or persistent epithelial defect. The mean time to re-epithelialisation was 22.8 days. Overall improvement in visual acuity was observed in 92.9% of 14 eyes with visual potential. Of those, five eyes gained six or more lines, two eyes gained between four and five lines, six eyes gained between one and three lines, and one eye lost three lines of Snellen acuity. Pain and photophobia were abolished in 86% of cases and substantially reduced in 14%, with all eyes exhibiting decreased vascularisation and inflammation at final follow up. CONCLUSIONS: Amniotic membrane transplantation appears to be a safe and effective method of restoring a stable corneal epithelium for cases of partial limbal stem cell deficiency and can be considered as an alternative to limbal autograft or allograft. (+info)Mutations in the RPGR gene cause X-linked cone dystrophy. (6/64)
X-linked cone dystrophy is a type of hereditary retinal degeneration characterized by a progressive dysfunction of the day vision or photopic (cone) system with preservation of night vision or scotopic (rod) function. The disease presents with a triad of photophobia, loss of color vision and reduced central vision. This phenotype is distinct from retinitis pigmentosa (RP) in which there are prominent night and peripheral vision disturbances. X-linked cone dystrophy is a genetically heterogeneous disorder, with linkage to loci on Xp11.4--Xp21.1 (COD1, OMIM 304020) and Xq27 (COD2, OMIM 303800). COD1 maps to a region that harbors the RPGR gene, mutations in which account for >70% of patients with X-linked RP. The majority of these mutations reside in one purine-rich exon, ORF15, encoding 567 amino acids with a repetitive domain rich in glutamic acid residues. We mapped two families with X-linked cone dystrophy to the COD1 locus and identified two distinct mutations in ORF15 in the RPGR gene (ORF15+1343_1344delGG and ORF15+694_708del15) leading to a frame-shift and premature termination of translation in one case and a deletion of five amino acids in another. Consistent with expression of RPGR in rods and cones, our results show that mutations in RPGR, in addition to X-linked RP, can also cause cone-specific degeneration. (+info)A health intervention programme for children with albinism at a special school in South Africa. (7/64)
The genetic condition albinism has a high frequency among the Sotho people of northern South Africa. Affected children have pale hair, eyes and skin-a dramatic contrast to the normal dark pigmentation. Their visual performance is poor and many attend special schools for the visually impaired. Children with albinism experience problems that are, on the one hand, physiological, and, on the other, social-psychological and educational in nature. In this self-report study 38 children at a rural special school described their eye and skin problems, a direct result of their lack of pigmentation, as well as strategies they adopted to manage their condition. A further section of the study deals with the social adaptation difficulties experienced by these children. The questionnaire tested for local belief systems about albinism and how these impact on the socialization of children with albinism. The intervention strategy proposed in this study is based on the assumption that any attempt to address both the health and social problems should be of a holistic, interactionist nature, and be based on the values and belief systems of the local community. In addressing the physical problems, the proposed intervention programme focuses on sensible sun protection habits from a young age and the active participation of the children. To alleviate the social problems a team (interactionist) approach including children, teachers, parents, health officials and the wider community is recommended. (+info)Enteroviruses and sudden deafness. (8/64)
A young, healthy man presented with sudden severe sensorineural hearing loss and tinnitus. The results of the workup and neuroimaging were normal, as were the auditory brain stem responses. Methylprednisolone pulse therapy was associated with significant hearing improvement within 10 days. A history of a short self-limited febrile illness preceding admission (with headache, photophobia, myalgia and fatigue), a raised serum C-reactive protein level and transient leukopenia suggested an infectious cause. Lumbar puncture revealed a mononuclear pleocytosis of the cerebrospinal fluid, with negative cultures but positive polymerase chain reaction test results for enterovirus, which was later cultured from the patient's stool. The patient's wife and baby had had a similar febrile illness without hearing loss 10 days earlier, and an outbreak of enterovirus meningitis was identified in the area, which was associated with familial clustering and echovirus serotype 4 infection. The varied causes of sudden sensorineural hearing loss, which should include enterovirus, are reviewed here. (+info)Photophobia is a condition characterized by an abnormal sensitivity to light. It's not a fear of light, despite the name suggesting otherwise. Instead, it refers to the discomfort or pain felt in the eyes due to exposure to light, often leading to a strong desire to avoid light. This can include both natural and artificial light sources.
The severity of photophobia can vary greatly among individuals. Some people may only experience mild discomfort in bright light conditions, while others may find even moderate levels of light intolerable. It can be a symptom of various underlying health issues, including eye diseases or disorders like uveitis, keratitis, corneal abrasions, or optic neuritis, as well as systemic conditions such as migraines, meningitis, or certain medications that increase light sensitivity.
Acitretin is a synthetic form of retinoic acid, which is a type of vitamin A. It is used to treat severe psoriasis and other skin conditions. Acitretin works by slowing down the rapid growth of skin cells that cause the symptoms of psoriasis. It comes in the form of a capsule and is taken orally.
Common side effects of acitretin include dryness of the skin, lips, and mouth, itching, peeling, redness, or stickiness of the palms and soles, hair loss, and changes in nail growth. Less common but more serious side effects can include liver damage, increased levels of lipids in the blood, and birth defects if taken during pregnancy.
It is important to note that acitretin can cause birth defects, so women who are pregnant or planning to become pregnant should not take this medication. Additionally, because acitretin can remain in the body for a long time, it is recommended that women of childbearing age use effective contraception while taking this medication and for at least three years after stopping it.
Ichthyosis is a group of skin disorders that are characterized by dry, thickened, scaly skin. The name "ichthyosis" comes from the Greek word "ichthys," which means fish, as the skin can have a fish-like scale appearance. These conditions can be inherited or acquired and vary in severity.
The medical definition of ichthyosis is a heterogeneous group of genetic keratinization disorders that result in dry, thickened, and scaly skin. The condition may affect any part of the body, but it most commonly appears on the extremities, scalp, and trunk. Ichthyosis can also have associated symptoms such as redness, itching, and blistering.
The severity of ichthyosis can range from mild to severe, and some forms of the condition may be life-threatening in infancy. The exact symptoms and their severity depend on the specific type of ichthyosis a person has. Treatment for ichthyosis typically involves moisturizing the skin, avoiding irritants, and using medications to help control scaling and inflammation.
Hyperacusis is a hearing disorder characterized by an increased sensitivity to sounds, where certain everyday noises are perceived as being excessively loud or uncomfortable, even painful. This condition can lead to avoidance behaviors and have a negative impact on a person's quality of life. It is different from normal hearing and requires medical evaluation to diagnose and manage.
Color vision defects, also known as color blindness, are conditions in which a person has difficulty distinguishing between certain colors. The most common types of color vision defects involve the inability to distinguish between red and green or blue and yellow. These deficiencies result from an alteration or absence of one or more of the three types of cone cells in the retina that are responsible for normal color vision.
In red-green color vision defects, there is a problem with either the red or green cones, or both. This results in difficulty distinguishing between these two colors and their shades. Protanopia is a type of red-green color vision defect where there is an absence of red cone cells, making it difficult to distinguish between red and green as well as between red and black or green and black. Deuteranopia is another type of red-green color vision defect where there is an absence of green cone cells, resulting in similar difficulties distinguishing between red and green, as well as between blue and yellow.
Blue-yellow color vision defects are less common than red-green color vision defects. Tritanopia is a type of blue-yellow color vision defect where there is an absence of blue cone cells, making it difficult to distinguish between blue and yellow, as well as between blue and purple or yellow and pink.
Color vision defects are usually inherited and present from birth, but they can also result from eye diseases, chemical exposure, aging, or medication side effects. They affect both men and women, although red-green color vision defects are more common in men than in women. People with color vision defects may have difficulty with tasks that require color discrimination, such as matching clothes, selecting ripe fruit, reading colored maps, or identifying warning signals. However, most people with mild to moderate color vision defects can adapt and function well in daily life.
A migraine disorder is a neurological condition characterized by recurrent headaches that often involve one side of the head and are accompanied by various symptoms such as nausea, vomiting, sensitivity to light and sound, and visual disturbances. Migraines can last from several hours to days and can be severely debilitating. The exact cause of migraines is not fully understood, but they are believed to result from a combination of genetic and environmental factors that affect the brain and blood vessels. There are different types of migraines, including migraine without aura, migraine with aura, chronic migraine, and others, each with its own specific set of symptoms and diagnostic criteria. Treatment typically involves a combination of lifestyle changes, medications, and behavioral therapies to manage symptoms and prevent future attacks.
Keratolytic agents are substances that cause the softening and sloughing off of excess keratin, the protein that makes up the outermost layer of the skin (stratum corneum). These agents help to break down and remove dead skin cells, increase moisture retention, and promote the growth of new skin cells. They are commonly used in the treatment of various dermatological conditions such as psoriasis, eczema, warts, calluses, and ichthyosis. Examples of keratolytic agents include salicylic acid, urea, lactic acid, and retinoic acid.
Alopecia is a medical term that refers to the loss of hair or baldness. It can occur in various parts of the body, but it's most commonly used to describe hair loss from the scalp. Alopecia can have several causes, including genetics, hormonal changes, medical conditions, and aging.
There are different types of alopecia, such as:
* Alopecia Areata: It is a condition that causes round patches of hair loss on the scalp or other parts of the body. The immune system attacks the hair follicles, causing the hair to fall out.
* Androgenetic Alopecia: Also known as male pattern baldness or female pattern baldness, it's a genetic condition that causes gradual hair thinning and eventual hair loss, typically following a specific pattern.
* Telogen Effluvium: It is a temporary hair loss condition caused by stress, medication, pregnancy, or other factors that can cause the hair follicles to enter a resting phase, leading to shedding and thinning of the hair.
The treatment for alopecia depends on the underlying cause. In some cases, such as with telogen effluvium, hair growth may resume without any treatment. However, other forms of alopecia may require medical intervention, including topical treatments, oral medications, or even hair transplant surgery in severe cases.
Mydriasis is a medical term that refers to the dilation or enlargement of the pupil, which is the black circular opening in the center of the iris (the colored part) of the eye. The pupil normally adjusts its size in response to changes in light levels and emotional state. In mydriasis, the pupil becomes widely dilated and less responsive to light. This can occur naturally due to factors such as strong emotions, fear, or physical exertion, but it can also be caused by certain medications, eye drops, or medical conditions like brain injuries or neurological disorders. It is important to note that mydriasis can affect one or both eyes and may have different clinical significance depending on the context.
Blepharospasm is a medical condition characterized by involuntary spasms and contractions of the muscles around the eyelids. These spasms can cause frequent blinkings, eye closure, and even difficulty in keeping the eyes open. In some cases, the spasms may be severe enough to interfere with vision, daily activities, and quality of life.
The exact cause of blepharospasm is not fully understood, but it is believed to involve abnormal functioning of the basal ganglia, a part of the brain that controls movement. It can occur as an isolated condition (known as essential blepharospasm) or as a symptom of other neurological disorders such as Parkinson's disease or dystonia.
Treatment options for blepharospasm may include medication, botulinum toxin injections, surgery, or a combination of these approaches. The goal of treatment is to reduce the frequency and severity of the spasms, improve symptoms, and enhance the patient's quality of life.
The Trigeminal Caudal Nucleus, also known as the nucleus of the spinal trigeminal tract or spinal trigeminal nucleus, is a component of the trigeminal nerve sensory nuclear complex located in the brainstem. It is responsible for receiving and processing pain and temperature information from the face and head, particularly from the areas innervated by the ophthalmic (V1) and maxillary (V2) divisions of the trigeminal nerve. The neurons within this nucleus then project to other brainstem regions and ultimately to the thalamus, which relays this information to the cerebral cortex for conscious perception.
"Migraine with Aura" is a neurological condition that is formally defined by the International Classification of Headache Disorders (ICHD) as follows:
"An migraine attack with focal neurological symptoms that usually develop gradually over 5 to 20 minutes and last for less than 60 minutes. Motor weakness is not a feature of the aura."
The symptoms of an aura may include visual disturbances such as flickering lights, zigzag lines, or blind spots; sensory disturbances such as tingling or numbness in the face, arms, or legs; and speech or language difficulties. These symptoms are caused by abnormal electrical activity in the brain and typically precede or accompany a migraine headache, although they can also occur without a headache.
It's important to note that not all people who experience migraines will have an aura, and some people may have an aura without a headache. If you are experiencing symptoms of a migraine with aura or any other type of headache, it is recommended that you consult with a healthcare professional for proper diagnosis and treatment.
A headache is defined as pain or discomfort in the head, scalp, or neck. It can be a symptom of various underlying conditions such as stress, sinus congestion, migraine, or more serious issues like meningitis or concussion. Headaches can vary in intensity, ranging from mild to severe, and may be accompanied by other symptoms such as nausea, vomiting, or sensitivity to light and sound. There are over 150 different types of headaches, including tension headaches, cluster headaches, and sinus headaches, each with their own specific characteristics and causes.
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.
