What are the early symptoms of pterygium?
summary
Pterygium is a common and frequently occurring disease in ophthalmology. It 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. What are the early symptoms of pterygium? Next, I'd like to share my views with you.
What are the early symptoms of pterygium?
First, most of them have no conscious symptoms or only mild discomfort. When the pterygium extends to the cornea, astigmatism occurs due to involvement; Or because the pterygium extends into the corneal surface to cover the sleeping hole and cause visual impairment, very serious cases can affect eye movement in varying degrees.
Second: unilateral pterygium is more common in the nasal side, while bilateral pterygium is located in the nasal and facial sides of the cornea. In the early stage, the limbal became gray, the bulbar conjunctiva became congested and hypertrophic, and then developed into triangular vascular tissue. It can be divided into head, neck and body. The tip is the head, the limbal is the neck, and the bulbar conjunctiva is the body.
Third: pterygium can be divided into progressive stage or quiescent stage according to its pathological changes. The head of progressive pterygium was raised, the cornea was turbid nearby, and there were cell infiltration in the layer of elasticity and shallow stroma. The neck is wide, the body is thick, the surface is uneven, and there are thick and dilated blood vessels. Pterygium in quiescent stage had flat head, corneal infiltration and absorption, no or slight congestion in the body, smooth surface and quiescent lesions.
