Purpose: To compare choroidal thickness in patients with epiretinal membrane according to existence of cystoid macular edema after vitrectomy
Methods: This retrospective, observational study included patients diagnosed with epiretinal membrane treated with vitrectomy and membrane peeling. Twenty eyes with cystoid macular edema after vitrectomy (group 1) and 112 eyes without cystoid macular edema after vitrectomy (group 2) were compared. At the 6 months follow-up, subfoveal choroidal thickness (SFCT), central foveal thickness (CFT), and changes in best corrected visual acuity (BCVA) were evaluated
Results: The mean occurrence period for cystoid macular edema was 2.89 months in group 1 patients. There were no significant differences in SFCT preoperatively, and at postoperative 1 week, 1 month, and 6 months, but SFCT significantly differed at postoperative 3 month (group 1, 253.0 μm; group 2, 179.3 μm; p = 0.036). There were no significance differences in preoperative and postoperative CFT and BCVA
Conclusions: At the time that cystoid macular edema occurs after vitrectomy and membrane peeling, SFCT increased and there was no correlation between CFT and BCVA.
