AIM: To assess the efficacy and safety of ranibizumab in the treatment of choroidal neovascularisation (CNV) caused by pathologic myopia (PM). DESIGN: Prospective, multicentre, interventional case series. METHODS: 40 eyes of 39 consecutive patients with PM and CNV were treated with 'on demand' intravitreal injection of ranibizumab 0.5 mg. Final best corrected visual acuity (BCVA) and its change from baseline were the main outcome measures. Changes in optical coherence tomography (OCT) central retinal thickness (CRT) were a secondary outcome. RESULTS: Mean age was 53±13 years and mean refractive error -13.5±6.5 D. Median follow-up was 13.3±2 (range 12-18) months. Fifteen eyes (37.5%) had previously been treated with photodynamic therapy (PDT). The mean baseline logarithm of the minimum angle of resolution (logMAR) BCVA (Early Treatment Diabetic Retinopathy Study (ETDRS) vision chart) was 0.68±0.34 (Snellen equivalent 20/131) and 21±16 letters. The final mean logMAR BCVA was 0.27±0.2 (p = 0.008) (20/42) and 40.5±14 letters (p = 0.01). Mean final VA improved in 82.5% of patients, in 60% by 3 or more lines (median number of lines gained 2.9). Even six out of seven cases of low vision (≤1.1 logMAR) at the final examination has improved vision. Mean OCT CRT reduced from 218±70 to 175±46 μm (p 0.02). Age and previous PDT did not influence the results (p>0.05). The mean number of injection was 2.8±1.2 (range 1-6). No ocular or systemic side effects were observed. CONCLUSION: Ranibizumab was an effective treatment for stabilising and improving vision with a low number of injections in 92.5% of patients with myopic CNV in a long-term follow-up.
