Diseases of Macula
Age related Macular Degeneration
Age related degeneration on macular occurs declining of view ability. There often appear symptoms like distortion, lack of view field or blurred vision.
Central Serous Chorioretinopathy
Disability of retinal pigment epithelium pile up exudate on Macular and occur lowering vision. This disease occurs frequently middle and old aged female. Early on there are often no symptoms. Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. While it does not result in complete blindness, loss of central vision can make it hard to recognize faces, drive, read, or perform other activities of daily life.Macular degeneration typically occurs in older people. Genetic factors and smoking also play a role. It is due to damage to the macula of the retina. Diagnosis is by a complete eye exam. The severity is divided into early, intermediate, and late types. The late type is additionally divided into “dry” and “wet” forms with the dry form making up 90% of cases.
Epi Retinal Membrane
An epiretinal membrane is a thin sheet of fibrous tissue that develops on the surface of the macula and can cause problems with central vision. Most epiretinal membranes happen because the vitreous (the jelly inside the eye) pulls away from the retina. This most commonly happens to people over the age of 50. The membrane may also form following eye surgery or inflammation inside the eye.
A macular hole is a small break in the macula, located in the center of the eye’s light-sensitive tissue called the retina. Depending upon the degree of attachment or traction between the vitreous and the retina, there may be risk of developing a macular hole in the other eye. Patients who has macular hole often complain lack of center of view field.
Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye (a yellow central area of the retina) and causes it to thicken and swell (edema). The swelling may distort a person’s central vision, because the macula holds tightly packed cones that provide sharp, clear, central vision to enable a person to see detail, form, and color that is directly in the centre of the field of view.
