Pterygium Surgery
Pterygium Surgery
Pterygium is a relatively frequent condition where a wing- shaped fold of conjunctiva with brovascular tissue invades the super scial cornea. The condition is often preceded with degenerative changes occurring in the interpalpebral bulbar conjunctiva such as pingueculum.
The prevalence of pterygium varies from 1 to 15% depending on the geographical location of the population under analysis1. The main risk factors are the total exposure to ultra-violet (UV) light and increasing age1. One plausible hypothesis for its pathogenesis is that the effects of UV radiation causes actinic change in the conjunctiva layers, resulting in abnormal growth2.This growth may be exacerbated by hot, dry or windy environmental conditions. Those patients with lifestyles that have greater exposure to these conditions e.g. outdoor pursuits and residence in sunny environments, have a greater risk of developing pterygia1, 2.
The main clinical considerations are the effect of the pterygium on the patient’s vision, the possibility of malignant change, the presence of ocular irritation and cosmetic appearance to the patient. These factors will determine whether surgery is justified.

Abstract
Pterygium is a relatively frequent condition where a wing- shaped fold of conjunctiva with brovascular tissue invades the super scial cornea. The condition is often preceded with degenerative changes occurring in the interpalpebral bulbar conjunctiva such as pingueculum.
The prevalence of pterygium varies from 1 to 15% depending on the geographical location of the population under analysis1. The main risk factors are the total exposure to ultra-violet (UV) light and increasing age1. One plausible hypothesis for its pathogenesis is that the effects of UV radiation causes actinic change in the conjunctiva layers, resulting in abnormal growth2.This growth may be exacerbated by hot, dry or windy environmental conditions. Those patients with lifestyles that have greater exposure to these conditions e.g. outdoor pursuits and residence in sunny environments, have a greater risk of developing pterygia1, 2.
The main clinical considerations are the effect of the pterygium on the patient’s vision, the possibility of malignant change, the presence of ocular irritation and cosmetic appearance to the patient. These factors will determine whether surgery is justified.
