ABSTRACT
BACKGROUND:
To evaluate the efficacy of intravitreal ranibizumab for subfoveal choroidal neovascularization (CNV) from age-related macular degeneration (AMD) with combined severe diabetic retinopathy (DR).METHODS:
This retrospective, interventional case series included eleven patients (mean age, 70.09 years; range, 54 to 83 years) with at least severe non-proliferative DR and subfoveal CNV secondary to AMD. Each subject was treated with intravitreal injections of 0.5 mg ranibizumab. The primary outcomes included change in best-corrected visual acuity and central subfield thickness (CST) on optical coherence tomography (OCT).RESULTS:
The mean follow-up time was 16.7+/-14 months (range, 6 to 31 months). Mean visual acuity improved from 1.21+/-0.80 logarithm of the minimum angle of resolution (logMAR) to 1.0+/-0.6 logMAR (P=0.107), 0.95+/-0.62 logMAR (P=0.044), 1.10+/-0.68 logMAR (P=0.296), and 1.13+/-0.66 logMAR (P=0.838) at 1, 3, 6, and 12 months after injection, respectively. Eight patients (72.7%) gained or maintained vision (mean 0.32 logMAR), whereas three patients (27.3%) lost more than one line of vision (mean 0.51 logMAR). The mean OCT CST was 343.9+/-134.6 microm at baseline, and the mean CST at 1, 3, 6, 12 months after the injection was 367.8+/-172.1 (P=0.864), 346.2+/-246.2 (P=0.857), 342+/-194.1 (P=0.551), and 294.2+/-108.3 microm (P=0.621), respectively.CONCLUSION:
Intravitreal ranibizumab injection can be considered to be a therapy for the stabilization of subfoveal CNV secondary to AMD with combined severe DR. However, these patients might exhibit limited visual improvement after treatment.
