Abstract :
Objective: The study is focused on the analysis of visual consequences in patients who suffer from diabetic
retinopathy. The patients involved were treated using pan retinal photocoagulation with or without sub-Tenon
triamcinolone acetonide.
Patients and Methods: The subjects were divided into two groups based on the treatment i.e. sub-tenon
triamcinolone with pan retinal photocoagulation (Group 1) and pan retinal photocoagulation alone (Group 2). The
cases were randomly distributed among both the groups. Change in visual acuity was considered to be the only
major variable factor in this study. Visual acuity was checked after two months from the treatment and difference
was measured from the standard readings.
Results: The patients treated with a combination of sub-tenon triamcinolone and pan retinal photocoagulation
showed improvement in visual acuity much greater than the patients who were treated with pan retinal
photocoagulation only. The difference was statistically significant (p < 0.005). 73% of patients in Group 1 were
having improved visual acuity as compared to only 6.6% of patients in Group 2.
Conclusion: Sub-Tenon triamcinolone acetonide injection has proved to be an outstanding treatment in the
deterrence of pan retinal photocoagulation. The visual acuity has improved much with the dose of the said injection
and the visual loss caused by macular edema is minimized.
