Purpose: To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. Methods: Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). Results: Forty eyes were included in the study. CRT significantly decreased from 410.4 ± 64.8 µm at baseline to 303.2 ± 24.3 µm at month-12, p < 0.0001. Similarly, CST was significantly reduced from 436.4 ± 120.4 µm at baseline to 322.9 ± 54.2 µm at month-12, p < 0.0001. Total macular volume and CSV were significantly reduced from 9.95 ± 1.68 mm3 and 0.38 ± 0.11 mm3 at baseline to 8.49 ± 0.83 mm3 and 0.31 ± 0.05 mm3 at month-12, respectively (p < 0.0001 each, respectively). BCVA significantly improved from 0.26 ± 0.17 Snellen equivalent at baseline to 0.65 ± 0.19 at month-12, p < 0.0001. Mean DexI administered during the study were 2.0 ± 0.3. Neither DME subtype nor previous treatment status had any effect on functional or anatomic outcomes. Regarding safety, one (2.5%) eye developed ocular hypertension, which was successfully controlled with topical hypotensive treatment. Conclusions: DexI was and effective and safe strategy for managing DME in diabetic patients undergoing uneventful cataract surgery.

Abstract

Purpose: To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. Methods: Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). Results: Forty eyes were included in the study. CRT significantly decreased from 410.4 ± 64.8 µm at baseline to 303.2 ± 24.3 µm at month-12, p < 0.0001. Similarly, CST was significantly reduced from 436.4 ± 120.4 µm at baseline to 322.9 ± 54.2 µm at month-12, p < 0.0001. Total macular volume and CSV were significantly reduced from 9.95 ± 1.68 mm3 and 0.38 ± 0.11 mm3 at baseline to 8.49 ± 0.83 mm3 and 0.31 ± 0.05 mm3 at month-12, respectively (p < 0.0001 each, respectively). BCVA significantly improved from 0.26 ± 0.17 Snellen equivalent at baseline to 0.65 ± 0.19 at month-12, p < 0.0001. Mean DexI administered during the study were 2.0 ± 0.3.
