Purpose: To study the efficacy of a single 0.7 mg dexamethasone intravitreal implant in vitrectomized eyes with refractory macular edema secondary to combined cataract extraction and macular pucker removal. Methods: In 8 eyes of 8 consecutive patients with refractory macular edema secondary to combined cataract extraction and 25-gauge vitrectomy with internal limiting membrane peeling for macular pucker removal, the injection of the 0.7 mg dexamethasone implant was performed. Best-corrected visual acuity, central retinal thickness measured by spectral domain optical coherence tomography, and intraocular pressure were evaluated at baseline, 1 month, and 6 months. Results: After a mean follow-up of 6.75 +/- 0.71 months, best-corrected visual acuity was significantly increased (P < 0.0001) from 20/50 to 20/23 (P < 0.0001), mean central retinal thickness decreased significantly from 439 +/- 45 [mu]m to 296 +/- 49 [mu]m (P < 0.0001), and intraocular pressure changed significantly (P = 0.02) from 14.63 +/- 1.19 to 16 +/- 0.93. In no case postoperative hypotony or other complication was observed. Conclusion: A single injection of the 0.7 mg dexamethasone intravitreal implant resulted effective in the treatment of refractory macular edema secondary to combined cataract extraction and vitrectomy for macular pucker removal allowing a stable visual acuity recovery.

Abstract

Purpose: To study the efficacy of a single 0.7 mg dexamethasone intravitreal implant in vitrectomized eyes with refractory macular edema secondary to combined cataract extraction and macular pucker removal. Methods: In 8 eyes of 8 consecutive patients with refractory macular edema secondary to combined cataract extraction and 25-gauge vitrectomy with internal limiting membrane peeling for macular pucker removal, the injection of the 0.7 mg dexamethasone implant was performed. Best-corrected visual acuity, central retinal thickness measured by spectral domain optical coherence tomography, and intraocular pressure were evaluated at baseline, 1 month, and 6 months. Results: After a mean follow-up of 6.75 +/- 0.71 months, best-corrected visual acuity was significantly increased (P < 0.0001) from 20/50 to 20/23 (P < 0.0001), mean central retinal thickness decreased significantly from 439 +/- 45 [mu]m to 296 +/- 49 [mu]m (P < 0.0001), and intraocular pressure changed significantly (P = 0.02) from 14.63 +/- 1.19 to 16 +/- 0.93. In no case postoperative hypotony or other complication was observed. Conclusion: A single injection of the 0.7 mg dexamethasone intravitreal implant resulted effective in the treatment of refractory macular edema secondary to combined cataract extraction and vitrectomy for macular pucker removal allowing a stable visual acuity recovery.
