Treatment of Primary Pterygium With No Previous Pterygium Excision

This protocol addresses the management of a primary pterygium — a pterygium that has not been previously excised. Compared to recurrent cases, primary pterygia carry a lower risk of recurrence following intervention, making the initial management decision clinically important.

The primary objective in early-stage primary pterygium is relief from foreign body sensation and improvement of ocular comfort.

For early-stage disease, the approach centres on conservative symptomatic management using ocular lubricant preparations to provide comfort and reduce irritation. Additional short-term topical options may be considered when inflammation is present. The complete structured regimen — including specific agent selection, sequencing, and escalation criteria — is in the full protocol.
