| Pterygium, complete obstruction of visual axis | |
| Advanced pterygium originated from the nasal side of the sclera. nearly sompletely covering the pupil. This raised, wedge-shaped growth of the conjunctiva is due to a basophilic degeneration of the subepithelial substantia propria together with fibovascular proliferation. Pterygium is common in tropical countries and patients often present an advanced stage. Although a benign condition, pterygium should not be operated lightly because recurrence rate following excision is high. | |
