Abstract
Purpose: To evaluate the efficacy and safety of posterior sub?Tenon triamcinolone (PSTA) in chronic postoperative cystoid macular edema (PCME) after pars plana vitrectomy (PPV). Methods: Consecutive 22 patients who developed chronic PCME after PPV and underwent PSTA treatment were included in this retrospective study. Best?corrected visual acuity (BCVA) and central macular thickness (CMT) were measured pre injection and post injection at one month, three months, six months, and at last visit. The patients were divided into three groups according to the injection response status: complete, partial, and resistant. Results: The mean follow?up period was 26.4 ± 16.2 months after PSTA. According to pre?injection values, there was a significant improvement in the values of BCVA and CMT at the first, third, and sixth months and at the last examination (P < 0.05). In the final examination, PCME recovered completely in 12 patients, partially in 8 patients, and resistance was observed in 2 patients. Conclusion: Posterior sub?Tenon triamcinolone seems to be effective in chronic PCME following PPV.
