PURPOSE: This study aimed to evaluate the efficacy of multiple injections of intravitreal bevacizumab for treatment-naïve subfoveal occult choroidal neovascularization (CNV) in age-related macular degeneration (AMD).

METHODS: Twelve eyes of 12 patients (mean age 76 +/- 6 years) with mean best corrected visual acuity (BCVA) of 20/100 and occult subfoveal CNV at fluorescein angiography (FA), indocyanine-green (ICG) angiography and optical coherence tomography (OCT), showing intra- or subretinal fluid with or without retinal pigment epithelial detachment (PED), underwent multiple intravitreal injections (mean 2.4 +/- 0.7) of 1.25 mg (0.05 ml) bevacizumab. Visual acuity and OCT findings were assessed at the end of follow-up.

RESULTS: After a mean follow-up of 5.7 +/- 2 months, BCVA improved from 20/100 (range 20/50-20/303) to 20/60 (range 20/28-20/200) (p = 0.038). Five eyes (42%) increased BCVA by > or = 3 lines, six eyes (50%) increased BCVA by < 3 lines and one eye (8%) remained stable. Macular thickness decreased from 298 +/- 71 microm to 223 +/- 72 microm (p = 0.017). No ocular or systemic side-effects were observed.

CONCLUSIONS: Short-term results suggest that multiple intravitreal injections of 1.25 mg bevacizumab are well tolerated and associated with significant improvements in BCVA and decreased retinal thickness by OCT in most patients with treatment-naïve occult CNV. Further evaluation of intravitreal bevacizumab for the treatment of occult CNV is warranted.
