ABSTRACT
To compare the efficacy of injection of extralesional subcutaneous triamcinolone and intralesional triamcinolone in the treatment of primary chalazion. Randomized controlled trial. Armed Forces Institute of Ophthalmology [AFIO] Rawalpindi, from 1[st] September 2011 to 31[st] March 2012. Ninety two patients fulfilling the selection criteria were randomly divided into two groups of 46 patients each group A intralesional triamcinolone [IT] patients received a single extralesional subcutaneous triamcinolone injection while group B extralesional triamcinolone [ET] patients received intralesional triamcinolone injection. Main outcome measure was reduction in chalazion size to 2mm or smaller after steroid injection at 4 weeks follow up visit. The size of chalazion was measured at baseline and then at 2 weeks and 4 weeks post steroid injections. Data analysis was done by "statistical package for social sciences [SPSS] version 13.0 for windows. Both the groups were age matched with mean age of 30.46 +/- 10.09 years in group A and 29.13 +/- 6.04 yrs in group B. Among the subjects, there were 64 male and 28 female patients. Out of 92 patients, resolution was seen in 84.8% [39 out of 46 cases] in ET group and 82.6% [38 out of 46 cases] in IT group at 4 weeks follow up that was not statistically significant [p = 0.45]. Injection of extralesional subcutaneous triamcinolone is as effective as intralesional triamcinolone in treatment of chalazion
