Comparative Study of Effectiveness of Subconjunctival Injection of Dexamethasone Versus Intracameral Injection of Dexamethasone in Controlling Immediate Post-Operative Anterior Uveitis After Cataract Surgery in Cases of Phacomorphic Glaucoma

Abstract

Purpose: To compare the effectiveness of subconjunctival injection of dexamethasone with intracameral injection of dexamethasone in controlling immediate postoperative anterior uveitis after cataract surgery in patients of phacomorphic glaucoma.

Materials and Methods: Sixty patients of phacomorphic glaucoma underwent conventional Extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation by same surgeon. They were divided into two groups comprising of 30 patients each. Patients in Group A, received subconjuctival injection of deamethasone while patients in group B received intracameral injection of dexamethasaone at the end of surgery. Patients were examined on 1st and 3rd post-operative day on slitlamp for signs of anterior uveitis.

Results: on 1st post-operative day, in group A findings were, cells in AC ? +2 (17 patients, 57%), cells in AC ? +3 (11 patients, 36%), membrane in AC (19 patients, 63%) while in group B findings were, cells in AC ? +2 (14 patients, 47%), cells in AC ? +3 (13 patients, 43%), membrane in AC (21 patients, 70%). The data was analyzed statistically by applying T test using SPSS version 8. It showed that there was no statistically significant difference in results between group A and group B on 1st and 3rd post-operative day.

Conclusion: Intracameral injection of Dexamethasone provides an equally effective alternative to subconjunctival injection of Dexamethasone peroperatively and avoids the adverse effects associated with subconjunctival injection.
