Abstract Purpose:To report a case of choroidal neovascularization(CNV)after combination therapy with dabrafenib mesilate and trametinib dimethyl surfoxide.

Case:A 52-year-old woman with visual acuity loss in left eye after combination therapy with dabrafenib and trametinib. Best corrected visual acuity was 1.0 in the right eye and 0.1 in the left eye. Several mottled white lesions were seen in both fundi, Optical coherence tomography showed subretinal fibrin and serous retinal detachment in the macula of the left eye. Indocyanine green angiography showed multiple mottled hypofluorescence in both eyes. Fluorescein angiography showed classic CNV pattern in the left eye. Optical coherence tomography angiography showed the CNV in nasal of the macula.

 Based on the above findings, it was diagnosed as secondary CNV after combination therapy with dabrafenib and trametinib. After multiple rounds of anti-VEGF therapy, the exudative changes almost disappeared and the visual acuity improved.

Conclusions:The development of CNV during treatment with the combination of dabrafenib and trametinib for malignant melanoma is rare. It showed good responsiveness to treatment with anti-VEGF therapy.
