Aim To assess the efficacy of intravitreal ranibizumab for the treatment of new onset inflammatory choroidal neovascularisation (iCNV), including both uveitic and idiopathic CNVs.
Methods Single-centre, open-label, non-randomised Phase IIb clinical trial. Patients fulfilling strict entry criteria of new onset iCNV were given monthly intravitreal ranibizumab injections for 3months. Thereafter, re-treatment was based on evidence of persisting activity. All patients completed trial follow-up. Optical coherence tomography (OCT) and best-corrected visual acuity (BCVA) were performed at every visit. Fluorescein angiography was performed at baseline, months 4 and 12. Descriptive analysis and Wilcoxon non-parametric test were performed for analysis.
Results 15 patients, 10 women with a mean age of 48.8years (range 24-85years) were included in the study. The mean number of injections was 4.33 (range 3-7). There was a statistically significant difference in the BCVA at month 4 (p=0.001) and at month 12 (p=0.001) compared with baseline. The mean gain in BCVA at month 4 compared with baseline was 2015.36 letters (meanSD), and at month 12 was 21 +/- 16.97 letters. There was a statistically significant difference in the mean central subfield thickness (CST) at baseline versus month 4 (p=0.003) and month 12 (p=0.001).
Conclusion Patients gained vision (mean of 21 letters at 12months) and showed reduced CST. These results support the continued use of ranibizumab in the treatment of iCNV.
