Abstract

Purpose : To analyze contrast sensitivity of intravitreal bevacizumab injections with optimizing glycemic control versus optimizing glycemic control (in combination with sham injections) in eyes with diabetic macular edema (DME)

Methods : Forty-one eyes of 34 patients with type 2 diabetes mellitus and DME with glycated hemoglobin (HbA1c) <11% received either intravitreal bevacizumab injection (Group 1) or sham injection (Group 2) at 0 and 6 weeks along with optimizing glycemic control. Mean change in best-corrected visual acuity (BCVA), contrast sensitivity (CS), optical coherence tomography (OCT)-measured by central macular thickness (CMT) were compared and correlated at baseline, 2, 6 and 12 weeks.

Results : The study showed a mean CS improved in group 1 from 1.14±0.36 logCS to 1.32±0.24 logCS and also in group 2 from 1.11±0.29 logCS to 1.18±0.29 logCS at 12 weeks (P = 0.12). CS and CMT promptly decreased in group 1 compared to group 2 at 2 weeks ( CS improvement = 0.15±0.25 vs. 0.03±0.15 logCS; P = 0.04; CMT improvement = 116±115 vs. 17±71 μm; P = 0.01). There was a mean reduction of approximately 0.5% in HbA1c levels in both groups at 12 weeks (P = 0.002). The correlation between CS vs. BCVA at baseline was negative and statistically significant (r = -0.70; P < 0.001; n=41).

Conclusions : The study suggests the use of bevacizumab in combination with optimizing glycemic control for promptly improvement of contrast sensitivity in type 2 diabetes patients with DME. However, the optimizing glycemic control itself has shown also to be effective at 12 weeks.
