- Farsightedness (hyperopia)
- Nearsightedness (myopia)
Dry eye occurs when the eyes are not sufficiently moisturized. This can lead to redness, foreign body sensation, itching, tearing, and pain from the dry areas on the surface of the eye. The eyes may become dry because the tear film evaporates too quickly or because the tears themselves have a chemical imbalance or a combination of both.
Floaters and flashes are symptoms of the eye that commonly occur as a result of changes to the vitreous gel in the back of the eye. When we are born, the vitreous is firmly attached to the retina and is a thick, firm, jello-like substance. As we age, the vitreous becomes thinner and more watery, and tissue debris and fibers that were once secure in the firm gel can now move around inside the eye, casting shadows on the retina.
A cataract is a clouding of the normally clear lens of the eye that typically occurs with age. It is still the leading cause of blindness in the world and represents an important cause of visual impairment in the United States. Cataracts can be compared to a window that is frosted or fogged with steam and results in blurred vision. Catarats occur inside the eye and not on the surface of the eye; and, they can develop in one or both eyes.
Glaucoma is a series of diseases that result is damage to the optic nerves and eventual loss of vision. Glaucoma can affect anyone from newborn infants to the elderly. It is estimated that 3 million Americans have glaucoma. During this time, most people will NOT experience any symptoms. If left untreated, it can affect the vision and ultimately lead to permanent blindness.
Patients with diabetes are at an increased risk of developing eye diseases (retinopathy, cataracts, and glaucoma) that can lead to vision loss and blindness. Diabetic eye problems often develop without any noticeable vision loss or pain, so significant damage may already be present by the time patients notice any symptoms. Early detection of diabetic eye disease can help prevent permanent damage.
Macular degeneration is the breakdown and damage of the central retina, or macula. This small area in the back of the eye is responsible for crisp, detailed vision. If there is damage to the macula, the central part of our vision becomes distorted, blurry, or dark leading to difficulty reading, watching TV, driving, identifying faces, doing detailed work, and other daily tasks.
