Case report:Intravitreal Conbercept for treatment of choroidal neovascularisation secondary to choriodal osteoma

Background: Choriodal osteoma is a rare condition. Although anti-VEGF treatment has been reported to be effective in managing choroidal neovascularisation secondary to choriodal osteoma, to the best of our knowledge, this is the first report of using conbercept in such condition. Case presentation:This report describes a case of choroidal neovascularisation secondary to choriodal osteoma. A 37-year old female presented with decreased vision and distortion in left eye. Fundus image revealed an orange-yellow lesion with clear boundary in the macular area. Fluorescein angiography indicated choroidal neovascularization(CNV). OCT, B-scan and CT scan showed features of choroidal osteoma. Intravitreal Conbercept was given for four times over a period of 10 months, resulting stability of visual acuity and regression of CNV. Conclusions: Intravitreal Conbercept can be an effective modality in short term in controlling choroidal neovascularisation secondary to choriodal osteoma.
