Vision & Hearing

According to the CDC, the prevalence of vision impairment increases rapidly with age among all races and ethnicities.  Age Related Macular Degeneration is the leading cause of blindness in people over the age of 60.

Macular degeneration is the loss of central vision due to damage of the retina. Peripheral vision is retained.

Glaucoma is caused by fluid pressure on the optic nerve.

Cataracts are cloudy eye lenses which causes blurry vision. It is a common condition in people over 60.

Retinal detatchment is an emergency situation in which the retina at the back of the eye pulls away from its usual position.

Vitreous detatchment is the seperation of the gel in the back of the eye from the retina.  There is a danger of getting a tear in the retina.

Diabetic retinopathy is a complication of uncontrolled diabetes.  It causes damage to the blood vessels in the eye and vision impairment.

Color blindness is a reduced ability to distinguish colors, often genetic in origin.

Conjunctivitis (pink eye) is infection of the outer layer of the eye.

Grave's disease is an immune disorder of the thyroid gland.  It can cause eye symptoms like bulging eyes, double vision and light sensitivity.

Retinitis pigmentosa is an inherited degenerative eye disease in which the back wall of the retina is damaged.

Strabismus (crossed eyes) is a condition in which the eyes do not look in the same direction at the same time.

Amblyopia (lazy eye) begins in early childhood due to abnormal visual development.

Refractive error means that the shape of the eye does not bend light correctly, resulting in blurry vision.
