Choroidal dystrophy is an eye disorder involving the choroid, a layer of blood vessels between the sclera and retina.
Causes, incidence, and risk factorsChoroidal dystrophies are usually due to an abnormal gene (hereditary). It usually affects males, starting in childhood.
SymptomsThe first symptoms are peripheral vision loss and vision loss at night.
Signs and testsAn eye surgeon who specializes in the back of the eye (retina specialist) diagnoses choroidal dystrophies. The following tests may be needed to diagnose the condition:
- Electroretinography
- Fluorescein angiography
- Genetic testing
Choroidal dystrophies are usually treated with observation.

What else can I help you with?
What is retinal cryopexy?
a procedure that uses intense cold to induce a chorioretinal scar and to destroy retinal or choroidal tissue
Which arteries that supply thalamus?
mainly supplied by "posterior cerebral artery"few branches from "posterior communicating artery" and "inferior choroidal artery"
Wedge shaped thickening in the middle layer of the eyeball?
This description likely refers to a choroidal nevus, which is a common benign pigmented lesion in the choroid layer of the eye. Choroidal nevi are often wedge-shaped and can cause thickening in the middle layer of the eyeball without affecting vision. However, it is important to monitor these nevi for any changes that may indicate a need for further evaluation.
What is an icd-9 code for peripapillary atrophy?
363.50 = Hereditary choroidal dystrophy or atrophy, unspecified A more appropriate code may be 377.1 = Optic atrophy
Which parts of brain are supplied by the anterior choroidal artery?
choroid plexus in inferior temporal horn of lateral ventriclehippocampal formationamygdalaposterior portion of internal capsuleoptic tractcerebral peduncle of midbrain
What nutrients does blood give to the retina?
the layer that supplies blood to the retina is the "Sclera" which is the outermost layer of the eye.
How many eyes diseases are there?
Lots of them - Here are the names of them * Conjunctivitis (also known as pinkeye) * Stye * Retinitis pigmentosa * Pterygium * Iritis * Uveitis * Cyclitis * Chalazion * Hypophyon * Trachoma * Opthalmia or opthalmitis * Endopthalmitis * Panopthalmitis * Scleritis * Choroiditis * Coat's disease * Myopia (short-sight) * Hypermetropia (long-sight) * Astigmatism * Cataract * Macular degeneration * Tunnel vision * Optic neuritis * Blepharitis * Bupthalmos * Exopthalmos (bulging eyes) * Choroidal nevus * Melanoma, choroidal * Melanoma, iris * Retinoblastoma * Medulloepithelioma (also called diktyoma)
Is laser therapy used to treat retinal vein occlusion?
Although treatments for occlusion itself are limited, surgical treatment of the occlusion provides an option.
What does it mean if you have a birth mark on your leg?
Yes. A choroidal nevus is the name given to a spot, freckle or mole that appears inside the eye or on the eye's surface. Sometimes detected during a dilated eye examination, these pigmented spots are usually flat and slate-greyish in color. Choroidal nevi are commonly found in the choroid, a blood vessel-rich layer lying between the retina and the sclera. Although they are not necessarily a "normal" finding in our eyes, they are quite common and may not represent anything wrong with the eye.
Why did john speke go blind?
John Speke, the British explorer, suffered from a condition known as "choroidal inflammation," which is an inflammation of the choroid layer in the eye. This condition developed after he was injured during a hunting accident in 1861, leading to complications that ultimately resulted in his blindness. Despite his visual impairment, Speke continued to pursue his explorations and made significant contributions to the knowledge of East Africa.
What causes the red reflex?
The red reflex is caused by the reflection of light from the retina in the eye. When a light source, such as an ophthalmoscope, is directed into the eye, it illuminates the fundus, and the healthy retina reflects this light back, appearing red due to the rich vascularization and the presence of choroidal blood vessels. Any obstruction or abnormalities, such as cataracts or retinal detachments, can disrupt this reflex, indicating potential eye health issues.
What is responsible for nourishing the inner layers of the retina?
The inner layers of the retina are primarily nourished by the retinal pigment epithelium (RPE) and the choroidal circulation. The RPE, located just outside the retina, provides essential support and nutrients to the photoreceptors, while the choroid, a vascular layer beneath the RPE, supplies oxygen and additional nutrients to the outer layers of the retina. This dual supply is crucial for maintaining retinal health and function.
