Common Eye Problems

The eye, like most all other parts of the body, is subject to a variety of conditions that fall under the following categories: infection (eg, caused by bacteria, viruses, and fungi), inflammation, injury (trauma), heredity, aging changes, and degeneration.

While most of us during our lifetime may only suffer from a mild infection or inflammation in the eye(s), each part of the eye is subject to each of these categories of problems and, many times, several parts of the eye(s) are involved. For example, pink eye (conjunctivitis) is an eye infection, usually caused by viruses, that is common in children but can affect people of all ages. Contact lens wearers can get inflammation of the eye called contact lens solution toxicity due to sensitivity to the contact lens solution. A corneal abrasion (scratch of the cornea) is the result of injury to the cornea and, depending on the type of injury, may result in recurrent corneal erosion. Blepharitis is an inflammatory condition that can affect the upper eyelid(s), the lower eyelid(s), and even the conjunctiva (surface of the eye). Aging changes in the eye result in cataracts, flashes and floaters, and presbyopia.

Blepharitis Blepharitis is inflammation of the eyelids. When it involves the outside front of the eyelid, where the eyelashes are attached, it is called anterior blepharitis. If blepharitis involves the inner eyelid, it is…
Cataracts A cataract is any clouding of the human lens. This clouding can cause a reduction in vision. The lens is composed of protein and water structured to allow light to clearly pass through. Changes to the structure of the…
Pink Eye (Conjunctivitis) Pink eye (conjunctivitis) is an inflammation of the tissue on the surface of the eye and/or the inside lining of the eyelids.
Contact Lens Solution Toxicity Contact lens solution toxicity refers to those conditions in the eye that are the result of an unwanted reaction to the use of such solutions.
Corneal Abrasion A corneal abrasion is a scratch or cut (abrasion) of the clear outer layer (cornea) of the eye. Injury (trauma) is the most common cause for corneal abrasions.
Flashes and Floaters Flashes and floaters describes a condition that comes from changes in the back chamber of the eye (the posterior chamber, also known as the vitreous cavity).
Stye (Hordeolum and Chalazion) A stye (hordeolum) is a local, acutely inflamed growth (swelling, lesion) of the eyelid. They can occur at the lid margin or farther up the lid on either the inner (tarsal) side or the outer (skin) side of the lid. A…
Presbyopia Presbyopia is an age-related change in vision whereby one loses the ability to see near without corrective lenses or corrective surgery. The cause of presbyopia is a change in the ability of the human lens to change…
Corneal Foreign Body A corneal foreign body occurs when the cornea has a piece of foreign matter lodged in it. The most common types of foreign bodies include particles of dust, debris (eg, metal, wood), paint chips, and plant materials.
