Intravitreal bevacizumab as first local treatment for uveitis-related choroidal neovascularization: long-term results

Abstract

To report long-term results of intravitreal (IVT) bevacizumab as first local treatment for choroidal neovascularization (CNV) secondary to uveitis. Files of patients receiving 1.25 mg/0.05 ml bevacizumab as primary local treatment for CNV were retrospectively reviewed. Main outcomes were change in best-corrected visual acuity (BCVA) and central foveolar thickness (CFT), treatment-related adverse events, and number and frequency of injections. Fifteen eyes from fifteen patients were included. Multifocal choroiditis and panuveitis were the diagnosis in seven, ampiginous choroiditis in two, and for six remaining, serpiginous choroiditis, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, punctuate inner choroidopathy, tuberculosis and idiopathic inflammation. In 13 eyes, neovascularization was subfoveal, and peripapillary in two. Intraocular inflammation was strictly controlled in all cases by the time of injections. BCVA improved from logMar 0.53 to logMar 0.29 in 12 eyes (80%), while CFT decreased from 239.06 to 195.2 μm in 13 (87%). Twelve eyes received more than one injection; mean number in this group was 4.25 (2-8), and frequency 1 every 12.97 weeks. There were no adverse events related to bevacizumab or the procedure. Median follow-up was 17.6 months (8-25). First-intention IVT bevacizumab for inflammatory CNV showed transient improvement in BCVA and CFT, in eyes under controlled inflammation. Reinjection was needed in most cases. Further work should conclude about safety related to repeated injections.
