Aim: To evaluate the efficacy of intravitreal bevacizumab (IB) in the long-term control of subfoveal choroidal neovascularisation (CNV) associated with angioid streaks (AS).
Methods: Patients with unilateral active CNV associated with AS were enrolled. Exclusion criteria were previous treatment for CNV and comorbidity. Postoperative visual acuity was defined as a gain or loss of two or more lines of best-corrected visual acuity (BCVA). Post-treatment CNV size was dichotomised into “increased,” if the CNV area had grown by ⩾200 μm2, and “stable/reduced” if it had decreased by ⩾200 μm2 or had not changed by more than 200 μm2. Patients were retreated if no further improvement or worsening was noted.
Results: Patients were five males and six females aged 33 to 58 years (mean 46.8 (SD 9.2)), who received a mean number of 3.5 (1.3) IB treatments (min: 2; max: 6). The mean retreatment interval was 3 (1.5) months (min: 1; max: 6). The mean follow-up duration was 23.8 (2.9) months. At 20 months all patients had stable/reduced CNV size and stable/improved BCVA. The mean BCVA rose significantly from 0.28 (0.2) at baseline to 0.56 (0.29) at 20 months (p<0.0001).
Conclusion: IB is a promising tool for the long-term control of CNV in AS. Further studies are required to validate these findings.
