Abstract Details
Purpose:
To assess the efficacy of conjunctival autograft after pterygium excision with fibrin adhesive using conjunctiva over the pterygium.
Setting:
Single centre prospective case series Nethradhama Superspeciality Eye Hospital
Methods:
This study included 30 eyes of 30 patients with mean age of 40+/-10 years, who underwent pterygium excision with conjunctival autograft derived from the body of pterygium and attached using fibrin glue. The mean follow-up period was 6 months. On all post operative visits, changes in uncorrected visual acuity (UCVA), corrected distant visual acuity (CDVA), astigmatism , complications and evidence of recurrence were recorded.
Results:
Pre-operative CDVA in type 1 remained same but in type 2 and 3 there was a significant improvement. In type 2 pre-operative mean LogMar of 0.109±0.15 SD improved to 0.018±0.075 SD at post -operative 1 month which was statistically significant(p=0.03). However, in type 3 there was improvement in CDVA post-operative but it was not statistically significant attributing to significant corneal scarring. Mean astigmatism reduced significantly from preoperative value of 2.308D to 1.248D postoperatively (p<0.026). Minor post-operative complications such as congestion, chemosis, subconjunctival haemorrhage were seen, which resolved with time. No major sight threatening or graft-related complications were detected. There was no evidence of recurrence during a follow-up period of 6 months.
Conclusions:
Self conjunctival autograft following pterygium excision appears to be a feasible , safe and effective alternative method for management of pterygium. It also preserves the superior conjunctiva for future surgeries .However, longer follow up is required to study the long term outcomes, especially the incidence of recurrence.
