چکیده
Purpose: To evaluate changes in subfoveal choroidal thickness (SCT) in cases of tractional clinically significant macular edema (CSME) after pars plana vitrectomy (PPV) using Enhanced-depth optical coherence tomography (EDI-OCT). Methods: This quasi experimental study included 30 eyes of 30 patients who had underwent PPV for the management of tractional CSME. Best corrected visual acuity (BCVA) , subfoveal choroidal thickness (SCT) and central macular thickness( CMT) were measured before, 1 month, 3 and 6 months after PPV in operated and fellow eyes. Results: The preoperative mean SCT of eyes with tractional CSME and fellow eyes was 314/59±71.24 (206-478)μm and 283/56±97.48(142-405) μm, respectively. The postoper ative 1 month, 3 months, and 6 months mean SCT of operated and fellow eyes was 309/58±45/49(194-447), 304/58±32.79(209-435), 288/59±63.46(174-416), 288/59±63.46(174-416), 290/65±10.31(152-421) respectively. However, there were not a statistically significant decline in SCT 1 month and 3 months postoperative (P=0.54 and P=0.24, respectively), but a statistically significant decline in SCT was observed at 6 months in eyes with tractional CSME (p=0.009). Conclusion: There was a statistically significant decline in SCT 6 months postoperatively in eyes with tractional CSME. Type of surgery (PPV vs combined surgery) does not affect choroidal thicknessکلیدواژه ها
