3 Common Genetic Eye Disorders and How They Are Detected

Uncategorized

Some eye disorders are more likely in individuals with a family history due to genetic predisposition. It’s important to understand 3 of the most common eye disorders that may be more likely because of family history and how you can detect these disorders early to receive proper treatment.

Color Blindness

Color blindness actually refers to the inability to distinguish between certain colors. Some people are unable to see only 1 or 2 colors, while others see only black, white, and gray shades. It is caused when retinal cells are unable to detect certain wavelengths because of a defect in those cells. The optometrist can diagnose this condition using a simple test in which a colored letter or number is found in a pattern of dots or colored chips are arranged.

Glaucoma

Glaucoma can cause blindness from damaged optic nerves that result from abnormally high pressure inside the eye. This condition can be detected early on with regular optometrist visits. The test measures the pressure in the eye using a puff of air or tonometer instrument.

Cataracts

A cataract clouds the lens and causes blurry vision. Cataracts can be detected using a visual acuity test to determine how well a patient sees from different distances. Pupil dilation can help the optometrist see more of the lens. Fortunately, early detection of glaucoma and cataracts can result in very effective treatment that limits vision loss.
