Observing the factors affecting fibrovascular regrowth after pterygium excision and comparing the efficacy and complications of conjunctival autograft with sutures versus fibrin glue.

To observe the factors affecting fibrovascular regrowth after pterygium excision and to compare the efficacy and complications of conjunctival autograft with sutures versus fibrin glue. 65 consenting patients with primary pterygium attending the outpatient department having appropriate indications for surgery were enrolled. Data was collected using personal interviews. Routine pre-operative ophthalmic examination was done, including visual acuity assessment, slit lamp examination, and fundus evaluation. Pterygium excision surgery was done on all patients using either Fibrin Glue or 10-0 nylon sutures. Patients were followed up at weeks 1, 4, 12, and 24 and any complications were duly noted. The fibrin glue group showed milder postoperative discomfort, symptoms, and signs compared to the suture group. Pyogenic granuloma (3.12%), corkscrew vessels (6.25%), and subconjunctival hemorrhage (24.99%) were more common in the fibrin glue group. FVG not crossing the limbus was observed in 6.25% of glue cases and 9.09% of suture cases, more in fleshy and large pterygia, while age and gender did not alter the incidence of FVG. No recurrences were observed in any group. The incidence of fibrovascular regrowth (FVG) was not affected by age, gender, smoking, and surgical technique, but was positively correlated with length and grade of pterygium. The complication rate between the two groups was not found to be statistically significant. Despite causing severe postoperative discomfort and requiring prolonged surgical time, suture-assisted pterygium surgery is a cost-effective method still being used with long-term outcomes similar to fibrin glue.
