This situation is caused by damaged or thinning of macular tissues. Approximately 10% of macular degeneration in the category of exudative macular degeneration. Macules usually protected by a thin tissue that separates it from the blood vessels that gives a very smooth rear eye pressure. Sometimes, these blood vessels rupture or leak and cause scarring. This often results in the formation of new blood vessels are abnormal. The newly formed blood vessels are very fragile. They are fragile and can leak. Blood and fluid leak will damage the macula and cause scar tissue even more. Vision becomes blurred and distorted, while the thick scar tissue will prevent the degree of central vision in severe disability.

Sometimes trauma, infection, or inflammation can also damage the soft macular tissue. If only one eye degenerates, in the early stages of degeneration are not aware of, especially when the other eye is normal. Macular degeneration often occurs in one eye first, because it is aware of the possible new cases of visual impairment after the lapse of considerable time.

Macular degeneration can cause different symptoms in different people. Sometimes only one eye be myopic, while the other eye for years can still see well. But if macular degeneration occurs in both eyes, read and work at close range be very difficult. Macular degeneration alone does not cause total blindness. With peripheral vision is usually not affected, most of these patients can still take care of themselves properly.
