Disorders of the choroid including hereditary choroidal diseases, neoplasms, and other abnormalities of the vascular layer of the uvea.
A villous structure of tangled masses of BLOOD VESSELS contained within the third, lateral, and fourth ventricles of the BRAIN. It regulates part of the production and composition of CEREBROSPINAL FLUID.
The thin, highly vascular membrane covering most of the posterior of the eye between the RETINA and SCLERA.
Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS. (From Devita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072; J Neurosurg 1998 Mar;88(3):521-8)
A usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged CHOROID PLEXUS, which may be associated with oversecretion of CSF. The tumor usually presents in the first decade of life with signs of increased intracranial pressure including HEADACHES; ATAXIA; DIPLOPIA; and alterations of mental status. In children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. Malignant transformation to choroid plexus carcinomas may rarely occur. (Adams et al., Principles of Neurology, 6th ed, p667; DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072)
Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.
A watery fluid that is continuously produced in the CHOROID PLEXUS and circulates around the surface of the BRAIN; SPINAL CORD; and in the CEREBRAL VENTRICLES.
The pigmented vascular coat of the eyeball, consisting of the CHOROID; CILIARY BODY; and IRIS, which are continuous with each other. (Cline et al., Dictionary of Visual Science, 4th ed)
A thin membrane that lines the CEREBRAL VENTRICLES and the central canal of the SPINAL CORD.
The layer of pigment-containing epithelial cells in the RETINA; the CILIARY BODY; and the IRIS in the eye.
The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the canal of Schlemm. (From Cline et al., Dictionary of Visual Science, 4th ed)
Progressive, autosomal recessive, diffuse atrophy of the choroid, pigment epithelium, and sensory retina that begins in childhood.

Idiopathic central serous chorioretinopathy. (1/183)

Idiopathic central serous chorioretinopathy (ICSC) is usually seen in young males with Type A personality. Clinical evaluation of the macula with fundoscopy and biomicroscopy, coupled with fluorescein angiography establishes the diagnosis. Indocyanine green angiographic studies have reinformed that the basic pathology lies in choriocapillaries and retinal pigment epithelium. Most of the ICSC resolve completely in four months, and some of them could resolve early with direct photocoagulation of the leaking site. Oral steroids have no role, and could even cause an adverse reaction.  (+info)

The pathogenesis of choroidal neovascularization in patients with age-related macular degeneration. (2/183)

Laser photocoagulation and several experimental treatments for choroidal neovascularization (CNV) in patients with age-related macular degeneration attempt to ablate the neovascularization, but do not address underlying angiogenic stimuli. As a result, recurrences are a major problem. Drug treatment to counter the growth of CNV would be a major advance, but its development is impeded by lack of knowledge concerning the stimuli and other molecular signals involved in the pathogenesis of CNV. Herein we explore clues that can be gleaned from clinical, epidemiological, pathological, and experimental data. These suggest that abnormalities of the extracellular matrix of retinal pigmented epithelial (RPE) cells may promote a pro-angiogenic RPE phenotype that contributes to the development of CNV. This provides a general hypothesis that can be tested, but it is also necessary to test hypotheses regarding the specific alterations in gene expression that contribute to CNV. Identification of alterations in gene expression will provide targets for rational design of drug treatment.  (+info)

Autosomal dominant macular atrophy at 6q14 excludes CORD7 and MCDR1/PBCRA loci. (3/183)

PURPOSE: Localization of the gene responsible for autosomal dominant atrophic macular degeneration (adMD) in a large pedigree UM:H785. METHODS: Standard ophthalmologic examinations were performed. Microsatellite markers were used to map the disease gene by linkage and haplotype analyses. RESULTS: The macular degeneration in this family is characterized by progressive retinal pigment epithelial atrophy in the macula without apparent peripheral involvement by ophthalmoscopy or functional studies. Acuity loss progressed with age and generally was worse in the older affected individuals. The rod and cone function remained normal or nearly normal in all tested affected members up to 61 years of age. The phenotype in our family has characteristics similar to Stargardt-like macular degeneration with some differences. Haplotype analysis localized the disease gene in our adMD family to an 8-cM region at 6q14, which is within the 18-cM interval of STGD3 but excludes cone-rod dystrophy 7 (CORD7; centromeric) and North Carolina macular degeneration and progressive bifocal chorioretinal atrophy (MCDR1/PBCRA; telomeric). The mapping interval overlaps with that of recessive retinitis pigmentosa (RP25). CONCLUSIONS: These results implicate at least three genetically distinct loci for forms of macular degeneration that lie within a 30-cM interval on chromosome 6p11-6q16: CORD7, adMD, and MCDR1/PBCRA. Because the critical interval for the adMD family studied overlaps with STGD3 and RP25, these loci could be allelic.  (+info)

Fluorescein angiographic features of choroidal insufficiency in anterior ischemic optic neuropathy. (4/183)

Anterior ischemic optic neuropathy(AION) is known to be caused by circulatory disturbance in the anterior optic nerve(AON). Because the AON shares blood supply from the paraoptic short posterior ciliary artery with peripapillary choroid, the authors investigated the angiographic evidences of combined choroidal insufficiency in patients with acute AION. Fundus fluorescein angiograms from 30 eyes from 28 patients with acute AION were enrolled in this study. The diagnosis of acute AION was based primarily on angiographic evidences of filling delay of optic nerve head and the various clinical features, such as decreased visual acuity, visual field defects, afferent pupillary defect, and optic disc swelling. Angiographic evidences of combined choroidal filling delay were as follows: 1) circular or localized filling delay of peripapillary choroid in 15 eyes (50%), 2) generalized filling delay of posterior pole in 11 eyes (36.7%), 3) filling delay of unilateral choroid divided by watershed zone in 5 eyes (16.7%), and 4) choriocapillary filling delay in 10 eyes (33.3%). In this study, various types of choroidal insufficiency in patients with AION were observed, which helped us to differentiate AION from the other various diseases of the anterior optic nerve.  (+info)

Bullous variant of idiopathic central serous chorioretinopathy. (5/183)

BACKGROUND: Spontaneous bullous serous retinal detachment (RD) with subretinal exudation complicating idiopathic central serous chorioretinopathy (ICSC) is a rare and infrequently described clinical entity. Clinical observations are described on this variant form in 11 patients, the largest series reported to date. METHODS: 13 eyes of 11 Indian patients having this entity were followed up clinically and angiographically for 12-24 months (retrospective, longitudinal). None of the patients had any previous history of other diseases nor were they on any medications. Four eyes received laser treatment (group A); nine eyes were not treated (group B). RESULTS: All 11 patients were male, aged 23-49 years (median 37 years). The clinical and photographic records revealed subretinal exudation and inferior bullous serous RD complicating ICSC with evidence of large, single or multiple, leaking retinal pigment epithelial detachments (PEDs) in all the cases. In group A, resolution of serous RD occurred in 12 weeks (median) with a visual recovery of >/=20/30 in three out of four eyes while in group B resolution of serous retinal detachment was observed in 14 weeks (median) with eight out of nine eyes achieving a visual acuity of >/=20/30. Subretinal fibrosis developed in two eyes in group A and none of the eyes in group B. CONCLUSION: The disease is an exaggerated form of ICSC and can occur spontaneously without any history of corticosteroid therapy. Recognition of this atypical presentation is important to avoid inappropriate treatment. These observations suggest that with respect to the duration of the disease and the final visual outcome laser therapy offers no additional benefit over the natural course of this variant form of ICSC.  (+info)

CT-revealed choroidal effusions as a sign of carotid cavernous fistula. (6/183)

Choroidal effusions may appear as subtle abnormalities on CT scans. Recognition of choroidal effusions, however, is critical because they may be an early sign of ocular pathologic abnormality. After detection, the various causes of choroidal effusions, such as carotid cavernous fistulas, ocular hypotony, tumors, and inflammatory conditions, should be considered.  (+info)

Choroidal thickness changes during altered eye growth and refractive state in a primate. (7/183)

PURPOSE: In the chick, compensation for experimentally induced defocus involves changes in the thickness of the choroid. The choroid thickens in response to imposed myopic defocus and thins in response to imposed hyperopic defocus. This study was undertaken to determine whether similar choroidal changes occur in the primate eye with induced refractive errors. METHODS: Thirty-three common marmosets were used. Eyes in 26 monkeys served as untreated control eyes, and eyes in 7 received 3 weeks of monocular lid suture to induce changes in eye growth and refractive state. Refractive errors were measured using refractometry and retinoscopy, and axial ocular dimensions, including choroidal thickness, were measured using high-frequency A-scan ultrasonography. Eyes were measured before the lids were sutured and at frequent intervals after lid opening. RESULTS: In the marmoset, choroidal thickness ranges from 88 to 150 microm and increases significantly during the first year of life. Monocular lid suture initially results in short, hyperopic eyes that then become elongated and myopic. In these animals the choroids of both the experimental and the fellow control eyes also increase in thickness with age but additionally show interocular differences that vary significantly with the relative changes in vitreous chamber depth and refraction. In eyes that are shorter and more hyperopic than control eyes the choroids are thicker, and in eyes that are longer and more myopic than control eyes the choroids are thinner. CONCLUSIONS: In marmosets, the thickness of the choroid increases during postnatal eye growth. Superimposed on this developmental increase in choroidal thickness there are changes in thickness that are correlated with the induced changes in eye size. These changes are small (<50 microm) in comparison with those observed in the chick, contributing to less than a diopter change in refractive error.  (+info)

Early treatment with cyclosporin in serpiginous choroidopathy maintains remission and good visual outcome. (8/183)

AIMS: To describe management and clinical outcomes of serpiginous choroidopathy treated primarily with cyclosporin at a tertiary uveitis referral centre METHODS: A case series of 14 eyes of seven patients with serpiginous choroidopathy with follow up ranging from 1.3 to 13 years is described. All patients had fundus lesions consistent with serpiginous choroidopathy, were investigated for systemic disease, had fluorescein angiography, and were treated with combined immunosuppressive therapy including cyclosporin. RESULTS: No patients suffered significant loss of acuity after starting systemic immunosuppression with cyclosporin as the primary agent. All but one patient achieved remission and were able to stop medications with no recurrences in the follow up period. Side effects from cyclosporin were well tolerated and there were no serious complications from immunosuppression. CONCLUSIONS: Cyclosporin is a safe and effective option with which to manage serpiginous choroidopathy. Significantly, adequate immunosuppression can result in clinical remission and cessation of therapy in some patients.  (+info)

The choroid is a part of the eye located between the retina and the sclera, which contains a large number of blood vessels that supply oxygen and nutrients to the outer layers of the retina. Choroid diseases refer to various medical conditions that affect the health and function of the choroid. Here are some examples:

1. Choroidal neovascularization (CNV): This is a condition where new blood vessels grow from the choroid into the retina, leading to fluid accumulation, bleeding, and scarring. CNV can cause vision loss and is often associated with age-related macular degeneration, myopia, and inflammatory eye diseases.
2. Chorioretinitis: This is an infection or inflammation of the choroid and retina, which can be caused by various microorganisms such as bacteria, viruses, fungi, or parasites. Symptoms may include blurred vision, floaters, light sensitivity, and eye pain.
3. Choroidal hemorrhage: This is a rare but serious condition where there is bleeding into the choroid, often caused by trauma, high blood pressure, or blood clotting disorders. It can lead to sudden vision loss and requires urgent medical attention.
4. Choroideremia: This is a genetic disorder that affects the choroid, retina, and optic nerve, leading to progressive vision loss. It is caused by mutations in the CHM gene and primarily affects males.
5. Central serous retinopathy (CSR): This is a condition where fluid accumulates under the retina, often in the macula, causing distortion or blurring of vision. While the exact cause is unknown, CSR is thought to be related to stress, steroid use, and other factors that affect the choroid's ability to regulate fluid.
6. Polypoidal choroidal vasculopathy (PCV): This is a condition where abnormal blood vessels form in the choroid, leading to serous or hemorrhagic detachment of the retina. PCV is often associated with age-related macular degeneration and can cause vision loss if left untreated.

These are just a few examples of choroidal disorders that can affect vision. If you experience any sudden changes in your vision, it's important to seek medical attention promptly.

The choroid plexus is a network of blood vessels and tissue located within each ventricle (fluid-filled space) of the brain. It plays a crucial role in the production of cerebrospinal fluid (CSF), which provides protection and nourishment to the brain and spinal cord.

The choroid plexus consists of modified ependymal cells, called plexus epithelial cells, that line the ventricular walls. These cells have finger-like projections called villi, which increase their surface area for efficient CSF production. The blood vessels within the choroid plexus transport nutrients, ions, and water to these epithelial cells, where they are actively secreted into the ventricles to form CSF.

In addition to its role in CSF production, the choroid plexus also acts as a barrier between the blood and the central nervous system (CNS), regulating the exchange of substances between them. This barrier function is primarily attributed to tight junctions present between the epithelial cells, which limit the paracellular movement of molecules.

Abnormalities in the choroid plexus can lead to various neurological conditions, such as hydrocephalus (excessive accumulation of CSF) or certain types of brain tumors.

The choroid is a layer of the eye that contains blood vessels that supply oxygen and nutrients to the outer layers of the retina. It lies between the sclera (the white, protective coat of the eye) and the retina (the light-sensitive tissue at the back of the eye). The choroid is essential for maintaining the health and function of the retina, particularly the photoreceptor cells that detect light and transmit visual signals to the brain. Damage to the choroid can lead to vision loss or impairment.

Choroid plexus neoplasms are rare types of brain tumors that arise from the choroid plexus, which are clusters of blood vessels in the ventricles (fluid-filled spaces) of the brain. These tumors can be benign (choroid plexus papilloma) or malignant (choroid plexus carcinoma). Choroid plexus neoplasms most commonly occur in children under the age of 2, but they can also affect adults. Symptoms may include increased head circumference, hydrocephalus (fluid buildup in the brain), vomiting, and developmental delays. Treatment typically involves surgical removal of the tumor, followed by radiation therapy or chemotherapy for malignant tumors.

A choroid plexus papilloma is a rare, benign (non-cancerous) tumor that develops in the choroid plexus, which are clusters of blood vessels and specialized cells in the ventricles of the brain. These tumors can occur at any age but are more common in children under the age of 10.

Choroid plexus papillomas arise from the ependymal cells that line the ventricular system and produce cerebrospinal fluid (CSF). The tumor grows slowly and tends to block the flow of CSF, leading to increased intracranial pressure and symptoms such as headaches, vomiting, irritability, and developmental delays in children.

The medical definition of choroid plexus papilloma is: "A benign, slow-growing tumor that arises from the ependymal cells of the choroid plexus in the ventricles of the brain. The tumor can obstruct the flow of cerebrospinal fluid and cause increased intracranial pressure."

It is important to note that while choroid plexus papillomas are generally benign, they can still cause significant symptoms due to their location in the brain and the obstruction of CSF flow. Treatment typically involves surgical removal of the tumor, followed by radiation therapy or chemotherapy if necessary.

Choroid neoplasms are abnormal growths that develop in the choroid, a layer of blood vessels that lies between the retina and the sclera (the white of the eye). These growths can be benign or malignant (cancerous). Benign choroid neoplasms include choroidal hemangiomas and choroidal osteomas. Malignant choroid neoplasms are typically choroidal melanomas, which are the most common primary eye tumors in adults. Other types of malignant choroid neoplasms include metastatic tumors that have spread to the eye from other parts of the body. Symptoms of choroid neoplasms can vary depending on the size and location of the growth, but may include blurred vision, floaters, or a dark spot in the visual field. Treatment options depend on the type, size, and location of the tumor, as well as the patient's overall health and personal preferences.

Cerebral ventricle neoplasms refer to tumors that develop within the cerebral ventricles, which are fluid-filled spaces in the brain. These tumors can arise from various types of cells within the ventricular system, including the ependymal cells that line the ventricles, choroid plexus cells that produce cerebrospinal fluid, or other surrounding tissues.

Cerebral ventricle neoplasms can cause a variety of symptoms depending on their size and location, such as headaches, nausea, vomiting, vision changes, imbalance, weakness, or difficulty with mental tasks. The treatment options for these tumors may include surgical resection, radiation therapy, and chemotherapy, depending on the type and extent of the tumor. Regular follow-up care is essential to monitor for recurrence and manage any long-term effects of treatment.

Cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds and protects the brain and spinal cord. It acts as a shock absorber for the central nervous system and provides nutrients to the brain while removing waste products. CSF is produced by specialized cells called ependymal cells in the choroid plexus of the ventricles (fluid-filled spaces) inside the brain. From there, it circulates through the ventricular system and around the outside of the brain and spinal cord before being absorbed back into the bloodstream. CSF analysis is an important diagnostic tool for various neurological conditions, including infections, inflammation, and cancer.

The Uvea, also known as the uveal tract or vascular tunic, is the middle layer of the eye between the sclera (the white, protective outer coat) and the retina (the light-sensitive inner layer). It consists of three main parts: the iris (the colored part of the eye), the ciliary body (structures that control the lens shape and produce aqueous humor), and the choroid (a layer of blood vessels that provides oxygen and nutrients to the retina). Inflammation of the uvea is called uveitis.

The ependyma is a type of epithelial tissue that lines the ventricular system of the brain and the central canal of the spinal cord. These cells are specialized glial cells that help to form the blood-brain barrier, regulate the cerebrospinal fluid (CSF) composition, and provide support and protection for the nervous tissue.

Ependymal cells have a cuboidal or columnar shape and possess numerous cilia on their apical surface, which helps to circulate CSF within the ventricles. They also have tight junctions that help to form the blood-brain barrier and prevent the passage of harmful substances from the blood into the CSF.

In addition to their role in maintaining the integrity of the CNS, ependymal cells can also differentiate into other types of cells, such as neurons and glial cells, under certain conditions. This property has made them a topic of interest in regenerative medicine and the study of neurodevelopmental disorders.

The pigment epithelium of the eye, also known as the retinal pigment epithelium (RPE), is a layer of cells located between the photoreceptor cells of the retina and the choroid, which is the vascular layer of the eye. The RPE plays a crucial role in maintaining the health and function of the photoreceptors by providing them with nutrients, removing waste products, and helping to regulate the light that enters the eye.

The RPE cells contain pigment granules that absorb excess light, preventing it from scattering within the eye and improving visual acuity. They also help to create a barrier between the retina and the choroid, which is important for maintaining the proper functioning of the photoreceptors. Additionally, the RPE plays a role in the regeneration of visual pigments in the photoreceptor cells, allowing us to see in different light conditions.

Damage to the RPE can lead to various eye diseases and conditions, including age-related macular degeneration (AMD), which is a leading cause of vision loss in older adults.

The sclera is the tough, white, fibrous outer coating of the eye in humans and other vertebrates, covering about five sixths of the eyeball's surface. It provides protection for the delicate inner structures of the eye and maintains its shape. The sclera is composed mainly of collagen and elastic fiber, making it strong and resilient. Its name comes from the Greek word "skleros," which means hard.

Gyrate atrophy is a rare inherited eye disorder that is characterized by progressive degeneration of the retina, which is the light-sensitive tissue at the back of the eye. It is caused by a deficiency in an enzyme called ornithine aminotransferase (OAT), which is necessary for the normal metabolism of an amino acid called ornithine.

The accumulation of ornithine in the retinal cells leads to their degeneration and the formation of well-demarcated, circular areas of atrophy (gyrates) in the retina. This can result in decreased vision, night blindness, and a progressive loss of visual field, which can ultimately lead to legal or complete blindness.

Gyrate atrophy is typically inherited as an autosomal recessive trait, meaning that an individual must inherit two copies of the mutated gene (one from each parent) in order to develop the condition. The disorder usually becomes apparent in childhood or adolescence and can progress slowly over several decades. There is currently no cure for gyrate atrophy, but dietary restrictions and supplements may help slow its progression.
