 Retinitis Pigmentosa
Retinitis pigmentosa (RP) describes a group of related diseases that tend to run in families and cause a slow but progressive loss of vision. RP affects the rods and cones of the retina, the light-sensitive nerve layer at the back of the eye, and results in a decline in vision in both eyes. RP ...
- Retinal Side Effects From Systemic Medication
The retina is a layer of light-sensing cells that line the back of the eye. As light rays enter your eye, the retina converts the rays into signals that are sent through the optic nerve to your brain, where they are recognized as images. Certain systemic medications, which affect the entire bo ...
- Photodynamic Therapy for Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is a deterioration or breakdown of the macula. The macula is a small area at the center of the retina in the back of the eye that allows us to see fine details clearly and perform activities such as reading and driving. In exudative or “wet” AM ...
- Ocular Histoplasmosis Syndrome
Ocular histoplasmosis syndrome (OHS) is a major cause of visual impairment in the eastern and central United States, where 90% of adults have been exposed to Histoplasma capsulatum. This common fungus is found in molds from soil enriched with bat, chicken, or starling droppings and yeasts from ...
- Myopic Degeneration
Myopic degeneration is a condition characterized by progressive stretching of the eye that damages the retina, the layer of light-sensitive cells that lines the back of the eye. People with severenearsightedness (high myopia) are at greater risk for myopic degeneration. Myopic degeneration com ...
- Macular Hole
The macula is the part of the retina responsible for acute central vision, the vision you use for reading, watching television, and recognizing faces. A macular hole is a small, round opening in the macula. The hole causes a blind spot or blurred area directly in the center of your vision. Mos ...
- Macular Dystrophy
Macular dystrophy is a hereditary condition in which the macula degenerates. The macula is the part of your retina responsible for acute central vision, the vision one uses to read, watch television, and recognize faces. Symptoms of macular dystrophy can range from minimal vision loss and dist ...
- Macular Degeneration and Nutritional Supplements
Age-related macular degeneration (AMD) is a disease caused by damage or breakdown of the macula, the small part of the eye’s retina that is responsible for our central vision. This condition affects both distance and close vision and can make some activities (like threading a needle or r ...
- Lattice Degeneration
Lattice degeneration is a condition that causes thinning and weakening of the peripheral retina, the light-sensitive layer of cells lining the back of the eye, which can lead to a retinal tear. The vitreous, a clear, gel-like substance that fills the inside of the eye, is contained in a sac lo ...
- Indocyanine Green Angiography
Indocyanine green angiography (ICG) is a clinical test used to detect abnormal blood vessels in the choroid, the layer of blood vessels under the retina. These abnormal blood vessels, typically associated with macular degeneration, may cause bleeding, scarring, and vision loss. If the blood ves ...
- Fluorescein Angiography
Fluorescein angiography, a clinical test to look at blood circulation inside the back of the eye, aids in the diagnosis of retinal conditions associated with diabetes, age-related macular degeneration, and other eye abnormalities. The test can also help follow the course of a disease and monito ...
- Face-Down Recovery After Retinal Surgery
The retina is a layer of light-sensing cells lining the back of your eye. As light enters your eye, the retina converts the rays into signals that are sent through the optic nerve to your brain, where they are recognized as images. To repair a damaged or detached retina, your ophthalmologist m ...
- Cytomegalovirus Retinitis
Cytomegalovirus retinitis (CMV retinitis) is a serious eye infection of the retina, the light-sensing nerve layer that lines the back of the eye. It is a significant threat to people with weak immune systems, such as people with HIV and AIDS, newborns, the elderly, people undergoing chemotherap ...
- Cotton-Wool Spots
Cotton-wool spots are tiny white areas on the retina, the layer of light-sensing cells lining the back of the eye. Caused by a lack of blood flow to the small retinal blood vessels, they usually disappear without treatment and do not threaten vision. However, they can be an indication of a seri ...
- Coats' Disease
Coats disease is a chronic, progressive disorder that affects the retina, the light-sensitive nerve layer at the back of the eye. Coats disease is an abnormal growth spurt of the small blood vessels (capillaries) that nourish the retina. The fragile abnormal vessels break and leak the clear ser ...
- Central Serous Retinopathy
Central serous retinopathy (CSR) is a small, round, shallow swelling that develops on the retina, the light-sensitive nerve layer that lines the back of the eye. Although the swelling reduces or distorts vision, the effects are usually temporary. Vision generally recovers on its own within a fe ...
- Central Retinal Vein Occlusion
You probably know that high blood pressure and other vascular diseases pose risks to overall health, but you may not know that they can affect eyesight by damaging the veins in the eye. Central retinal vein occlusion (CRVO) blocks the main vein in the retina, the light-sensitive nerve layer at ...
- Central Retinal Artery Occlusion
You probably know that high blood pressure and other vascular diseases pose risks to your overall health, but you may not know that they can affect your eyesight by damaging the arteries in your eye. Central retinal artery occlusion (CRAO) usually occurs in people between the ages of 50 and 70 ...
- Branch Retinal Vein Occlusion
Most people know that high blood pressure and other vascular diseases pose risks to overall health, but many may not know that high blood pressure can affect vision by damaging the veins in the eye. High blood pressure is the most common condition associated with branch retinal vein occlusion ( ...
- Branch Retinal Artery Occlusion
Most people know that high blood pressure and other vascular diseases pose risks to overall health, but many may not know that high blood pressure can affect vision by damaging the arteries in the eye. Branch retinal artery occlusion (BRAO) blocks the small arteries in the retina, the light-se ...
