Description

Surgical removal of a pterygium followed by transplantation of the patient's own conjunctival tissue to the bare sclera to reduce recurrence risk.

Main Uses

Primary clinical use is the definitive surgical management of progressive or visually impairing pterygium — particularly recurrent pterygium, large primary pterygium extending beyond the pupillary margin, or cases causing astigmatism, corneal distortion, or cosmetic concern. It aims to reduce recurrence risk (compared to bare-sclera excision alone) by replacing the excised area with healthy autologous conjunctiva, restoring ocular surface integrity and limbal barrier function.

Normal Range

Not applicable — this is a surgical procedure, not a laboratory or diagnostic test with numerical values. There are no quantitative 'normal ranges' for pterygium excision with autologous conjunctival transplantation.

Low Values - Possible Causes

Not applicable — surgical procedures do not yield 'low values'. Abnormal outcomes (e.g., recurrence, graft failure, persistent inflammation) may occur due to inadequate surgical technique, poor wound healing, uncontrolled UV exposure, or underlying ocular surface disease (e.g., dry eye, limbal stem cell deficiency).

High Values - Possible Causes

Not applicable — surgical procedures do not produce 'high values'. Complications such as excessive fibrovascular proliferation, graft retraction, symblepharon, or postoperative infection may arise from surgical trauma, chronic inflammation, immunologic rejection (rare), or patient noncompliance with postoperative care.
