Intravitreal Bevacizumab for Management of Choroidal Osteoma without Choroidal Neovascularization

To report a patient with juxtapapillary choroidal osteoma (CO) with serous retinal detachment (SRD) not associated with choroidal neovascularization (CNV) who was successfully treated with a single intravitreal injection of bevacizumab. A 20-year-old woman presented with decreased vision in her right eye. Ultrasonography, fundus autofluorescence, fluorescein angiography (FA) and optical coherence tomography (OCT) were performed. She was diagnosed with juxtapapillary CO with SRD in the absence of CNV. The treatment involved a single intravitreal injection of bevacizumab. Visual acuity (VA) was 20/100 pre-injection which was dramatically improved to 20/20 one week after the injection without any additional treatment. Fundus examination and OCT one week after the injection revealed complete absorption of the subretinal fluid (SRF) in the macula. Eighteen months after the injection, vision remained stable and she did not show re-accumulation of SRF in her right eye. Intravitreal injection of bevacizumab may be effective in managing CO associated with SRF without CNV.
