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 microm at baseline and 169.50 microm 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.
