A triangular growth of fibrovascular tissue that extends from the conjunctiva (usually nasally) over the cornea.
a thickened triangular layer of conjunctiva extending from the nasal edge of the eye to the cornea; pterygia arise from irritation of the pinguecula
a common condition in which a small yellowish triangular patch of tissue, usually on the inner part of the whites of the eyes, develops and grows
a degenerative condition of the conjunctiva that progresses across the conjunctiva and onto the cornea
a fleshy growth, extending from the conjunctiva (white part of the eye) onto the cornea (clear part of the eye)
a fleshy growth on the conjunctiva which grows into the cornea
a fleshy growth that begins on the white part of the eye and grows onto the surface of the cornea (the clear front part of the eye)
a fleshy growth that invades the cornea
a fleshy triangular tissue that grows over the cornea, usually on the inner corner of the eye
a fleshy, wedge shaped growth on the cornea of the eye
a growth of fleshy tissue on the conjunctiva that extends over the cornea (the clear front window of the eye)
a growth of scar tissue and blood vessels on the sun-exposed surface of the eye in response to ultraviolet damage from the environment
a growth of the conjunctiva, the thin, transparent tissue that covers the outer surface of the eye and secretes oils and mucous to help lubricate the eye
a growth of tissue usually found in the shape of a triangle on the clear front covering of the eye (cornea)
a growth on the cornea that can cause irregular astigmatism and/or warping of the cornea
a growth on the front surface of the eye (conjunctiva and cornea)
a growth on the outside of the eye
a growth that begins in the corner of the eye and grows toward the cornea
an abnormal growth on the cornea of the eye
an elevated, superficial, external ocular mass that usually forms over the perilimbal conjunctiva and extends onto the corneal
a nonmalignant growth of the conjunctiva (overlying skin around the eye)
a nonmalignant lesion which invades the superficial cornea from the limbus
a pinkish, triangular-shaped tissue growth on the cornea
a raised, cream colored growth usually on the nasal side of the white of the eye
a raised, triangular or wedge-shaped growth of the conjunctiva
a similar fleshy growth of the conjunctiva next to the cornea that spreads across the cornea
a slightly raised, triangular shaped, yellowish lesion that usually occurs between the iris and the inner eye (near the nose)
a small, pink, triangular-shaped tissue that grows on the cornea
a small, triangle-shaped pinkish growth over the membrane covering the cornea of the eye
a triangular-shaped lump of tissue on the white of the eye, usually on the side closer to the nose
a triangular shaped, slightly elevated, and often red lesion,
a triangular thin transparent conjuctival fold visible mainly on the nasal side of the palpebral fissure
a wedge-shaped fibrovascular growth of conjunctiva that extends onto the cornea
a yellow-white triangular growth of tissue usually on the nasal side of the eyeball
Triangular-shaped fold of tissue on white of the eye. May eventually grow over part of the cornea. May be caused by irritation from sun, dust and wind.
A triangular growth of tissue that grows from the conjunctiva onto the cornea. If large it can cause astigmatism.
skin of scar tissue growing onto cornea
A small non-cancerous growth in the eye, arising from the outer layer of the eyeball. It is associated with long-term exposure to sunlight. Most pterygia are easily removed.
triangular thickening of bulbar conjunctiva advancing onto the cornea with apex toward pupil
A scarring condition of the cornea, caused by exposure to intense sunlight.
A thickening of the skin of the white of the eye that starts to grow onto the cornea. Usually due to many years of exposure to the sun. Can be surgically removed if interfering with vision.
Triangular fold of tissue on the white of the eye that can eventually grow over part of the cornea; the cause may be irritation from sun (i.e., UV rays), dust and wind. Some people have no symptoms, while others may have redness or blurred vision. Pterygia that are chronically inflamed can become itchy.
(tur-IH-jee-um). Wedge-shaped growth on the bulbar conjunctiva. May gradually advance onto the cornea and require surgical removal. Probably related to sun irritation.
Opaque triangular thickening of tissue extending from inner canthus to border or cornea with apex toward the pupil of the eye.
Pterygium usually refers to a benign growth of the conjunctiva. Alternately, it refers to any winglike triangular membrane occurring in the neck, eyelids, knees, elbows, ankles or digits (J Pediatr Orthop B 2004, 13:197-201). An example is popliteal pterygium syndrome, which affects the legs.
