Term | Definition |
---|---|
Age-Related Macular Degeneration | is an eye condition that leads to the deterioration of the macula, leading to loss of central vision. |
AIDS/HIV | is a virus that causes the body’s immune system to break down, leading to illness from infections. affect the eye by making the eyes susceptible to infection. |
Albinism | is a group of hereditary conditions that affect how the body produces or distributes pigment. have a reduced amount or absence of pigment in their eyes, hair and skin. |
Allergies | are a condition when the eyes react to an irritant or allergen, making them red, itchy, tearful and swollen. |
Amblyopia | is poor vision in an eye that did not develop normal sight during childhood. Lazy eye |
Anisocoria | when your pupils are different sizes. |
Astigmatism | is an imperfection in the curvature of your cornea — or in the shape of the eye’s lens, causing blurry or distorted vision. |
Avastin | is the brand name for bevacizumab, a drug injected into the eye to slow vision loss in people who have “wet” age-related macular degeneration (AMD). |
Bacterial Keratitis | is an infection of the cornea, often due to improper care and cleaning of contact lenses or from injury to the cornea. |
Bell’s Palsy | is a temporary condition that causes certain muscles in your face to weaken or become paralyzed. |
Black Eye | is bruising around the eye due to an injury to the face or head. |
Blepharitis | is inflammation (swelling) of the eyelids, where the upper and lower eyelids become coated with oily particles and bacteria near the base of the eyelashes. It causes irritation, itchiness, redness, and stinging or burning of the eye. |
Blocked tear duct | is when the eye’s drainage system for tears is either partially or completely obstructed. Tears cannot drain normally, causing a watery, irritated or chronically infected eye. |
Branch Retinal Vein Occlusion (BRVO) | is a blockage of the small veins in the retina. |
Cataracts | is a clouding of the eye’s normally clear lens, causing vision problems. |
Cellulitis | is a bacterial infection of tissue that can affect both the eyes and skin. |
Central Retinal Vein Occlusion (CRVO) | is a blockage of the main vein in the retina. |
Central Serous Retinopathy | fluid builds up under the retina and distorts vision. |
Chalazia and Styes | is a lump on the eyelid caused by enlarged oil-producing gland in the eyelid / is also a lump on the eyelid, usually caused by an infected eyelash follicle. |
Choroidal Neovascular Membranes | are new blood vessels that grow beneath the retina and disrupt vision. Is associated with many serious eye diseases. |
Coloboma | describes conditions where normal tissue in or around the eye is missing from birth. |
Color Blindness | occurs when you are unable to see colors in a normal way. Can happen when someone cannot distinguish between certain colors, usually between greens and reds, and occasionally blues. |
Conjunctivitis (Pink Eye) | is swelling of the conjunctiva — the thin, filmy membrane that covers the inside of your eyelids and the white part of your eye (sclera). |
Contact Lens-Related Eye Infections | The most common infection related to contact lens use is keratitis, an infection of the cornea (the clear, round dome covering the eye's iris and pupil). |
Corneal Abrasion | is a scratch or scrape on the eye’s cornea. |
Corneal Dystrophies | are a group of relatively rare genetic eye disorders in which abnormal material often accumulates in the cornea. |
Corneal Erosion | affects the cornea. The outermost layer of the cornea is the epithelium. When the epithelium does not stay attached correctly to the corneal tissue below |
Corneal Laceration | is a cut on the cornea. |
Corneal Ulcer | is an open sore on the cornea. |
Cytomegalovirus retinitis | is a serious viral eye infection of the retina, the light-sensing nerve layer that lines the back of the eye. It is most often found in people with compromised immune systems. |
Diabetic Retinopathy | is a common diabetic eye disease caused by changes in retinal blood vessels. |
Dilating Eyedrops | (called mydriatics) are used to dilate, or enlarge, the pupils of your eyes so that your eye doctor can see the inside of your eye in detail. |
Drusen | are yellow deposits under the retina. It likely does not cause age-related macular degeneration (AMD), their presence increases a person’s risk of developing AMD. |
Dry Eye | is a condition where the eyes don’t produce enough tears or the right quality of tears to be healthy or comfortable. |
Eye Cancer | is a malignancy that starts and grows in your eye. A malignancy is a group of cells that are cancerous and that can spread to other sites in the body or invade and destroy tissues. |
Eye Lymphoma | Primary intraocular lymphoma (PIOL) involves the retina, vitreous and optic nerve. Eighty percent of cases involve both eyes; many people with PIOL will develop lymphoma within the part of the brain called the cerebrum. |
Farsightedness (hyperopia) | is a refractive error, which means the eye does not bend or refract light properly. Distant objects look clear but close objects appear blurred. |
Floaters and Flashes | are shadows cast on the eye’s retina from clumps of gel or cells inside the vitreous / are flashes of light that you see when the vitreous gel pulls or rubs the retina. |
Fuchs' Dystrophy | is a progressive eye disease affecting the cornea, causing certain cells to deteriorate and die off, making corneal cells swollen and cloudy. |
Fungal Keratitis | is an infection of the cornea, often due to improper care and cleaning of contact lenses or from injury to the cornea. |
Giant Cell Arteritis | is a swelling of the arteries, the bv that carry blood away from heart. When they swell, it reduces the bf through these vessels. It affects the arteries in the neck, upper body and arms. Can cause sudden, painless vision loss. |
Glaucoma | is a disease that damages the eye’s optic nerve. |
Graves' Disease | is an autoimmune disorder that leads to over activity of the thyroid gland. The gland produces hormones that regulate your body’s metabolism. When it affects the eyes, the condition is known as thyroid eye disease. |
