Keratoconus Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. Keratoconus can occur in one or both eyes. Keratoconus is relatively rare. Most… Read More
Hyperopia Hyperopia, or farsightedness, is a common vision problem affecting about 25% of the U.S. population. People with hyperopia can usually see distant objects well, but have difficulty seeing objects that are up close. Signs and Symptoms of Hyperopia Farsighted people sometimes have headaches or eyestrain, and may squint or feel fatigued when performing work at… Read More
Glaucoma Glaucoma refers to a category of eye disorders often associated with a dangerous buildup of internal eye pressure (intraocular pressure or IOP), which can damage the eye’s optic nerve – the structure that transmits visual information from the eye to the brain. Glaucoma typically affects your peripheral vision first. This is why it is… Read More
Floaters and Spots Have you ever seen small specks or debris that look like pieces of lint floating in your field of view? These are called “floaters,” and they are usually normal and harmless. They usually can be seen most easily when you look at a plain background, like a blank wall or blue sky…. Read More
Eye Allergies Similar to processes that occur with other types of allergic responses, the eye may overreact to a substance perceived as harmful even though it may not be. For example, dust that is harmless to most people can cause excessive tear production and mucus in eyes of overly sensitive, allergic individuals. Also, eye allergies are… Read More
Dry Eye Syndrome Dry eye syndrome (DES or dry eye) is a chronic lack of sufficient lubrication and moisture on the surface of the eye. Its consequences range from minor irritation to the inability to wear contact lenses and an increased risk of corneal inflammation and eye infections. Signs and Symptoms of Dry Eye Persistent… Read More
Diabetic Retinopathy If you have diabetes, you probably know that your body can’t use or store sugar properly. When your blood sugar gets too high, it can damage the blood vessels in your eyes. This damage may lead to diabetic retinopathy. In fact, the longer someone has diabetes, the more likely they are to have… Read More
Cornea Transplant A cornea transplant replaces damaged tissue on the eye’s clear surface. Corneal transplants are often referred to as a keratoplasty, penetrating keratoplasty (PK) or corneal graft. In cases where the cornea has been damaged due to disease or injury, a cornea transplant replaces your tissue with healthy corneal tissue donated from an eye… Read More
Cataracts A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far… Read More
CMV Retinitis Cytomegalovirus (CMV) retinitis is a sight-threatening disease associated with late-stage AIDS (Acquired Immunodeficiency Syndrome). In the past, about 25% of active AIDS patients developed CMV retinitis. However, this figure appears to be dropping thanks to a potent combination of drugs that help restore the function of the immune system. CMV Retinitis Signs and… Read More
