                  Eye Diseases

                  Cataracts

                  Cataracts are caused by clouding of the lenses inside the eyes. The lens is made up of mostly water and proteins, which clumps together as we age. This will cause blurry vision and glare from sunlight or on coming headlights.

                  Diabetes & the Eye

                  Diabetes can damage multiple parts of the body including the eyes. Diabetes can cause leakage in the blood vessels that supply nutrition to the eyes, which can lead to permanent blindness if diabetes is not treated. The longer a person has diabetes the higher the risk.

                  Dry Eye

                  Dry eye is due to insufficient amount of tears to keep the eye lubricated and provide nutrition to the eye. With dry eye, people may feel the following symptoms in the eyes, irritated, gritty, scratchy, burning, excessive tearing, and blurred vision.

                  Floaters

                  Floaters are particles within the vitreous, which is the clear, jelly like fluid that fills the inside of your eyes. They can appear as small spots, thread like strands or cobwebs. Floaters that have been present for a long time or increase in number very slowly are harmless. However, if they appear abruptly or if there is a sudden increase in numbers, then you must be examined immediately to rule out retinal tear.

                  Glaucoma

                  Glaucoma is a group of diseases that damage the optic nerve of the eye, which leads to vision loss or blindness if left untreated. Anyone can develop glaucoma, but some people are at a higher risk than others. African-Americans over age 40, everyone over age 60 and anyone with family history of glaucoma are at higher risks.

                  Hypertension & the Eye

                  High blood pressure can damage the blood vessels of the eye and cause vision loss or blindness.

                  Keratoconus

                  Keratoconus is a condition where the cornea progressive thinning leads to a cone-shaped cornea rather than the normal dome-shaped. Vision is generally impaired even glasses will not improve vision in moderate to advanced stages. Generally, rigid gas permeable lenses are prescribed in moderate to advanced stages to improve vision.

                  Age-Related Macular Degeneration

                  Age-related macular degeneration (AMD) is one of the leading causes of vision loss and blindness among Americans age 65 and older. AMD causes a deterioration of central vision due damages of the macula, which is the part of the retina that allows you to see details.
