RÉSUMÉ
Objective: To evaluate the visual outcome in patients with diabetic retinopathy who underwent panretinal photocoagulation with or without sub-Tenon triamcinolone acetonide administration
Patients and Methods: Patients with severe non-proliterative diabetic retinopathy or proliferative diabetic retinopathy were randomized either to Group 1 [posterior sub-Tenon triamcinolone acetonide 20 mg injection and panretinal photocoagulation] or Group 2 [panretinal photocoagulation alone]. The primary variable was the change in best-corrected visual acuity at 2 months from the baseline
Results: The difference in visual acuity in the two groups post laser photocoagulation was statistically significant [p < 0.005]. Visual acuity improved in 73% of patients in Group 1 compared with only 6.6% of patients in Group 2
Conclusion: Posterior sub-Tenon triamcinolone acetonide injection has shown promising results in the prevention of panretinal photocoagulation- induced visual loss due to macular edema
