Concomitant use of conjunctival tissue graft from the pterygium itself without rotation in pterygium surgery: A full circle in conjunctival autografting

摘要

Purpose: The aim of this study is to describe a modified technique of using conjunctival tissue from the pterygium itself without any rotation of graft for the primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium using fibrin glue. Methods: In this retrospective, noncomparative, interventional case series, 98 eyes of 98 patients with primary pterygium operated between July 2011 to July 2016 were included. They underwent this technique from the pterygium tissue itself. There was no rotation of this graft, and it was adhered to the bare scleral defect with fibrin glue. Histopathological analysis of pterygium tissue was done to look for morphology and thickness of this thin conjunctival tissue obtained from pterygium tissue itself. The primary outcome measure was recurrence rate. Other outcome measures studied was graft retraction and graft edema. Results: The mean age was 52 ± 10.04 years. Mean follow-up was 14 ± 8.24 months. The only significant complication was recurrence rate of 4.08% (4 eyes out of 98). The most come secondary outcome was graft edema, 52.04% (51 eyes out of 98) which resolved without any intervention. Other outcome such as graft retraction, 32.65% was also recorded. Conclusion: Conjunctival tissue from the pterygium tissue itself without actual rotation appears to be a successful technique with lower recurrence rate for treating primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium.
