Abstract
Purpose:
The aim of this study was to assess the efficacy of phacoemulsification combined with intravitreal (i.v.t.) bevacizumab injection in diabetics with clinically significant macular edema (CSME) and cataract.
Methods:
This retrospective study included diabetic patients with cataract and CSME who underwent phacoemulsification and intraocular lens implantation with a 2.5-mg bevacizumab i.v.t injection (ivBe) (15 eyes) or without ivBe (controls, 14 eyes). Best-corrected visual acuity (BCVA), central macular thickness (CMT) measured by optic coherence tomography (OCT), and adverse events were recorded.
Results:
In the ivBe group, the OCT images demonstrated that CMT (mean ± standard deviation [SD]) decreased significantly from 466 ± 105 at baseline to 333 ± 107, 313 ± 138 and 333 ± 111 μm at 4, 8, and 12 weeks, respectively, after treatment (P < 0.05). The visual acuity in logMAR (mean ± SD) improved significantly from 1.66 ± 0.39 at baseline to 1.30 ± 0.50, 1.15 ± 0.42, 0.99 ± 0.48, and 1.03± 0.44 at 1, 4, 8, and 12 weeks, respectively, after treatment (P < 0.05). However, in the control group, the CMT changed insignificantly from 443 ± 109 at baseline to 463 ± 106, 425 ± 128, and 421 ± 119 μm at 4, 8 and 12 weeks, respectively after treatment (P > 0.05). The visual acuity in logMAR improved insignificantly from 1.63 ± 0.42 at baseline to 1.43 ± 0.53, and 1.39 ± 0.43 at 1, and 4 weeks (P > 0.05) and significantly to 1.24 ± 0.45 and 1.18 ± 0.44 at 8 and 12 weeks, respectively, after treatment (P < 0.05). None of the patients in both groups experienced injection- or surgery-related complications or any obvious systemic adverse events.
Conclusions:
The short-term results suggest that phacoemulsification with i.v.t. bevacizumab safely reduces macular edema and improves visual acuity for cataract and CSME in diabetics.
