PURPOSE: To evaluate the efficacy and safety of intravitreal ranibizumab in the treatment of choroidal neovascularization (CNV) due to pathological myopia (PM). METHODS: This retrospective case series studied outcomes in patients with CNV secondary to PM who were treated with intravitreal ranibizumab. Patients underwent complete ophthalmic evaluation, which included best-corrected visual acuity testing measured with Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography (OCT) and baseline fluorescein angiography (FA). Indications for retreatment included the persistence of subretinal fluid on OCT as well as hemorrhages and new CNV on FA. Patients were followed for a minimum of 12 months. RESULTS: We treated 29 eyes in 29 patients; the mean age was 56.8 years. Thirteen eyes were naïve, while 16 had been previously treated with photodynamic therapy or intravitreal bevacizumab. The mean initial visual acuity was 44.8 letters; at the 12-month follow-up, it was 53.7 letters. The mean OCT foveal thickness decreased by 35.3 μm. Patients received an average of 1.38 injections. Statistically significant differences were observed both in visual acuity and in central foveal thickness. All subgroups had favorable outcomes. None of the patients developed injection-induced complications or drug-related side effects. CONCLUSION: Intravitreal injection of ranibizumab appears to be safe and efficacious in patients with CNV secondary to PM followed over a 12-month period.
