To describe a patient with optic nerve head drusen who showed improved retinal hemorrhage and visual acuity following intravitreal anti-vascular endothelial growth factor (bevacizumab) injection. Case summary

A 53-year-old woman with no underlying disease presented with sudden vision loss in her left eye. Her best-corrected visual acuity was 1.0 in the right eye and 0.8 in the left eye; the intraocular pressure was 15 mmHg in both eyes. Anterior segment examination revealed no abnormal findings. Fundus examination showed subretinal hemorrhage and serous retinal detachment in the left eye. Fluorescein angiography and indocyanine green fundus examination revealed hyperfluorescence near the optic disc. The patient was diagnosed with choroidal neovascularization of the left eye secondary to optic nerve head drusen; intravitreal bevacizumab injection was then performed. Three weeks later, the patient showed improved retinal hemorrhage. Conclusions

Intravitreal anti-vascular endothelial growth factor injection may be an effective treatment for choroidal neovascularization associated with optic nerve head drusen.
