What is Pterygium? Is it dangerous and may lead to blindness? Or is it a transient and easy-to-treat condition? Read the article to know the details!
The sun’s ultraviolet (UV) rays play an important role in the appearance of pterygium, so the use of sun-blocking hats and sunglasses is recommended by people who live in sunny areas and spend a lot of time in the sun. Also, strong winds, dirt, and dust can cause the eye to exciting and thus the pterygium. The ingress of water into the eyes (while washing the face or showering) usually causes eye irritation in people with pterygium, causing burning and redness in the eye, so these people are advised to avoid water entering the eyes as much as possible.We call the pterygium a thin fibrovascular membrane of the conjunctiva tissue, in a triangular shape, which appears in the white part of the eye, usually in the lateral region closest to the nose, and can extend to the cornea (below we will explain the anatomical structures of the eyes with illustrations and photos).
Pterygium is a term of Greek origin, from the word pterygium, which means “wing”. The triangular appearance of the lesion usually resembles the wings of insects, which is why the disease received its name. Although benign in the sense that the lesion has nothing to do with cancer, the pterygium can have important adverse effects on vision, especially if the proliferation approaches or reaches the cornea. however, pinguecula is the name given to a small yellowish elevation, sometimes with some blood vessels, usually located in the same region as the pterygium. The pinguecula is a deposit of calcium, fat, and proteins in the conjunctiva, which expands, but does not usually reach the corneal region. Unlike the pterygium, which is usually restricted to the nasal portion of the eyes, the pinguecula can appear in the nasal, temporal portion, or both sides.
