Intravitreal bevacizumab in the management of subretinal fluid associated with choroidal osteoma

PURPOSE:: The purpose of this study was to evaluate the effect of intravitreal injection of bevacizumab on subretinal fluid associated with choroidal osteoma. METHODS:: In this retrospective noncomparative case series, eyes with serous retinal detachment involving the macula were treated with intravitreal injection of bevacizumab (1.25 mg/0.05 mL) and carefully followed-up with complete ophthalmic examination, including angiography and optical coherence tomography. The changes in best-corrected visual acuity and central foveal thickness were assessed by optical coherence tomography. RESULTS:: Six eyes received intravitreal injection of bevacizumab for serous retinal detachment. Only one eye had choroidal neovascularization associated with serous retinal detachment. The mean number of injections for the 6 eyes was 2.0 during the mean follow-up period of 11.3 months. The median logarithm of the minimum angle of resolution best-corrected visual acuity improved from 0.70 (Snellen equivalent, 20/100) at baseline to 0.30 (Snellen equivalent, 20/40; P = 0.043) at the final visit. The optical coherence tomography result also showed a significant reduction in central foveal thickness with a median central foveal thickness of 357.0 μm at baseline and 169.50 μm at the final visit (P = 0.028). The treatment was well tolerated, without ocular or systemic adverse events. CONCLUSION:: Intravitreal injection of bevacizumab for serous retinal detachment secondary to choroidal osteoma resulted in both visual and anatomical improvements.
