Glaucoma
Glaucoma is an eye disease in which the optic nerve in the eye is damaged in a pattern. Like Cateracts, it can permanently damage vision in the affected eyes, and lead to blindness if untreated. Glaucoma can be caused by a variety of factors including ethnicity, and genetics. Luckily there are several treatments for those who suffer with glaucoma.
Medication in the form of glaucoma eye drops can be easily administered to treat glaucoma. In extreme cases, surgery may be required, which can be both expensive and have side effects. As necessary as this case may be for some cases, this should be a step taken only after consulting with a physician and often after eye drops have been administered for some time.
