Eyelid fissure is a yellow-white, amorphous conjunctival degeneration that occurs in the bulbar conjunctiva near the limbus of the eyelid fissure. It is the deposition of vitreous and elastic tissue under the conjunctival epithelium. It is generally considered to be the degeneration of the bulbar conjunctiva caused by ultraviolet rays in the sun. Its cause is related to long-term outdoor activities. It is more common in middle-aged and elderly people. With the increase of age, the incidence rate increases, and it is generally bilateral.
The clinical manifestations of palpebral fissure can be foreign body sensation. The bulbar conjunctiva in the palpebral fissure area presents a slightly raised yellow-white plaque with a slightly raised triangle, which is mostly seen on the nasal side of the cornea, and a few on the temporal side. Eyelid plaque generally does not invade the cornea, but it can cause blepharitis, redness, foreign body sensation, burning sensation, etc.
Eyelid fissures generally do not need treatment, just observation. Severe effects on aesthetics and repeated chronic inflammation can be considered for surgery. Blepharitis can be treated with glucocorticoids such as flumetholone eye drops, and non-steroidal anti-inflammatory drugs such as pranoprofen eye drops.
Eyelid plaque is a common disease in ophthalmology. In order to prevent its occurrence and development, you can consider wearing anti-ultraviolet glasses, keep the environment quiet and tidy, and avoid adverse environmental stimuli such as strong light, sand, smoke and dust. Pay attention to rest, ensure adequate sleep, avoid excessive eye use; eat more fresh fruits and vegetables; avoid spicy food.
