PTERYGIUMS Meaning and
Definition
-
Pterygiums (plural of pterygium) are abnormal growths that appear on the conjunctiva, the thin, transparent tissue lining the inner part of the eyelids and covering the front portion of the eyeball. This condition is characterized by a fleshy, triangular-shaped tissue overgrowing onto the cornea, the clear front surface of the eye. Pterygiums typically develop on the side closer to the nose and gradually progress toward the center of the cornea, potentially obstructing vision if left untreated.
While the exact cause of pterygium formation is unknown, it is believed to be associated with excessive exposure to ultraviolet (UV) light, particularly from sunlight. Prolonged exposure to dry and dusty environments, as well as habitual eye irritation, may also contribute to its development. Symptoms commonly associated with pterygiums include redness, itching, blurred vision, and a sensation of discomfort or grittiness in the eyes.
Treatment options for pterygiums range from conservative management to surgical intervention. Mild cases can be managed through the use of lubricating eye drops, steroid eye drops, and the avoidance of environmental triggers. However, if pterygiums cause significant discomfort, affect vision, or cause persistent redness, surgical removal may be necessary. Surgery typically involves the excision of the abnormal tissue and the use of grafts to cover the affected area, reducing the risk of recurrence.
Regular eye examinations and adequate protection from UV light are essential preventive measures for minimizing the risk of pterygiums and maintaining optimal eye health.

Etymology of PTERYGIUMS
The word "pterygiums" is derived from the Greek word "pterygion" (πτερύγιον), which means "wing-like structure" or "little wing". The plural form, "pterygiums", is used to refer to multiple pterygiums, which are abnormal growths of the conjunctiva (thin tissue covering the white part of the eye) that extend onto the cornea. These growths are often triangular or wing-shaped, resembling the wings of a bird or a small wing. Therefore, the term "pterygiums" accurately describes the appearance of these growths.
