There are misconceptions among people who believe that one eye problems may aggravates any of other ones, for example, macular degeneration will aggravate glaucoma, or cataracts will aggravate macular degeneration. The fact is that macular degeneration is independent, and it is not tend to relate to some other conditions. In order to let you know they are unrelated, let's have a view of each eye condition respectively.

Macular degeneration is always referred as age-related macular degeneration. It is a medical condition which usually affects the elders that result in a loss of vision in the center of the visual field because of damage to the retina.

A cataract is a clouding that develops in the crystalline lens of the eye. It is related to aging, which is very common in older people. Although both macular degeneration and cataract are related to aging, they are totally two different types of eye condition. The former is something affecting the retina or the macula while the latter is not, and a cataract, unlike macular degeneration, can be cured by removing or replacing by new lenses.

Glaucoma is a disease that affects the optic nerve and involves loss of retinal ganglion cells in a characteristic pattern and it is usually caused by high pressure. In a closed and fluid-filled system, if there are too much fluid in eyes, eyes will suffer from increasing pressure. Glaucoma can be a very serious eye condition, if not treated in time, a risk of complete loss of eyesight can be caused. As a matter of fact, glaucoma is fairly easy to be treated at its early stage.

Diabetic retinopathy is damage to the retina caused by complications of diabetes mellitus, which can eventually lead to blindness. It is a leading cause of blindness in American adults. Patients with diabetic retinopathy suffer from vessels bleeding or constricting, causing retinal detachment. This eye condition is usually treated by laser in the early stage. Some patients may even need focal laser surgery more than once to control the leaking fluid. Diabetic retinopathy is not related to macular degeneration, but has an influence on glaucoma and cataracts.
