Glaucoma is an ocular disease that leads to the degeneration of retinal ganglion cells. In the chronic version of glaucoma, lack of pain creates patients that are often unaware that they their eyesight has begun to deteriorate. They remain unaware of their condition until they suddenly lose their sight due to leaving the disease untreated. Even when glaucoma is diagnosed, a considerable number ...
