Best disease (vitelliform macular degeneration) Best disease is an eye condition that affects a tiny part of the retina at the back of your eye, which is called the macula. Best disease can start to cause changes at the back of the eye between the ages of 3 to 15 although it does not usually affect vision until later on in life.way from the central macula is the peripheral retina, composed mostly of the other type of photoreceptor cells called rod cells. They enable us to see when light is dim and provide peripheral (side) vision outside of the main line of sight.

Interpreting and working with Deaf-Blind people The retina is a light-sensitive tissue at the back of the eye and is crucial for vision. As RP progresses, the field of vision narrows, a condition known as tunnel vision until only central vision (the ability to see straight ahead) remains. Many people with Usher syndrome also have severe balance problems.

Will working long hours on the computer be a problem for someone with a hole in the retina? Many patients have retinal holes associated with a condition called lattice vitreoretinal degeneration, or thinning of the retina. If the patient is asymptomatic, most studies have suggested that it is safe to observe the retinal hole without any treatment.

Age-Related Macular Degeneration Overview Macular degeneration is the leading cause of severe vision loss in people over age 60. It occurs when the small central portion of the retina, known as the macula, deteriorates. The retina is the light-sensing nerve tissue at the back of the eye.Because the disease develops as a person ages, it is often referred to as age-related macular degeneration (AMD). In the advanced stages, patients lose central vision. 2  Wet form. 3  The wet form of macular degeneration is characterized by the growth of abnormal blood vessels from the choroid underneath the macula. 4  This is called choroidal neovascularization.

Eye Tumors The retina is located at the back of your eye. Your inner eye, or the space between the posterior chamber behind the lens and the retina is the vitreous body. It is filled with a clear gel substance that gives the eye its shape. Light rays pass through the gel on their way from the lens to the retina.

EYE The retina is a multi-layered sensory tissue that lines the back of the eye. It is approximately 0.5mm thick, and consists of an outer pigmented layer of specialised epithelial cells and an inner neural portion. The middle of the retina is called the macula, and the centre of the macula contains the fovea. The fovea is specialised for detailed vision, and is naturally directed at objects when we look at them. The outer retinal pigment epithelium is a single layer of cells that abuts the underlying choroid.

Overview Dry macular degeneration is a common eye disorder among people over 65. It causes blurred or reduced central vision, due to thinning of the macula (MAK-u-luh). The macula is the part of the retina responsible for clear vision in your direct line of sight. Dry macular degeneration may first develop in one eye and then affect both.

INTERNATIONAL GUIDE DOG FEDERATION Flashes and Floaters (Posterior Vitreous Detachment). The space between the crystalline lens and the retina is filled with a clear, gel-like substance called vitreous. In a newborn, the vitreous has an egg-white consistency and is firmly attached to the retina.With age, the vitreous thins and may separate from the back of the eye. This is called posterior vitreous detachment (PVD), a very common, usually harmless condition.As the vitreous pulls free from the retina, light flashes or floaters often accompany it.Floaters are caused by tiny bits of vitreous gel or cells that cast shadows on the retina. Flashes occur when the vitreous tugs on the sensitive retina tissue. There are other more serious causes of flashes and floaters, however.n a newborn, the vitreous has an egg-white consistency and is firmly attached to the retina.

Frequently Asked Questions Diabetic Retinopathy. Diabetic retinopathy is a complication of diabetes that weakens the blood vessels that supply nourishment to the retina (the light-sensitive lining in the back of the eye where vision is focused). These weak vessels can leak, swell or develop thin branches, causing a loss of vision.

Central serous retinopathy Central serous retinopathy, also known as central serous chorioretinopathy, is an eye disease which causes visual impairment, often temporary, usually in one eye. When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula. This results in blurred or distorted vision. A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has d

Overview Eventually, the vitreous may separate from the surface of the retina — a common condition called posterior vitreous detachment (PVD). As the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. Left untreated, fluid from the vitreous cavity can pass through the tear into the space behind the retina, causing the retina to become detached. PVD can cause visual symptoms.

What Is Retinal Vein Occlusion? Your retina is a thin layer of tissue that lines the back of your eyeball. It turns light into signals to the brain, which interprets them as sight. When a vein in the retina becomes blocked, it’s called retinal vein occlusion. This can give you blurry vision or even sudden permanent blindness in that eye. It's similar to retinal artery occlusion, which is sometimes called an eye stroke. The damage happens when a blocked vein keeps blood from draining from the retina. That raises pressure inside your eye, which can cause bleeding, swelling, and fluid leaks. Retinal vein occlusion can harm your eye in minutes. Usually, a blood clot blocks the vein.
