What is pterygium

First of all: pterygium is a common and frequently occurring disease in Ophthalmology, which is called "pterygium climbing eye" in traditional Chinese medicine and "fish flesh" in common. It is generally believed that it is a chronic inflammatory disease caused by external stimulation. It is attacked by one eye or two eyes. It is named because its shape is similar to the wings of insects.

Secondly, it is a kind of vegetative tissue on the bulbar conjunctiva and cornea in the palpebral fissure, which increases gradually after invading the cornea, and even covers the pupil area, which seriously affects the vision. It is the degeneration, hypertrophy and hyperplasia of bulbar conjunctiva and subconjunctival tissue in the palpebral fissure, which develops into the cornea in a triangle. Most of them are outdoor workers, most of them are fishermen and farmers, which may be related to long-term chronic stimulation such as wind dust, sunlight and smoke.

Finally: it is not difficult, but it needs to be differentiated from pseudopterygium and palpebral fissure. True pterygium is the result of chronic inflammation of conjunctiva and subconjunctival tissue and development to cornea. Pseudopterygium is usually an acute injury in the limbic area of the cornea. The conjunctiva near it adheres to the corneal lesion and forms a conjunctival bridge.
