Photodynamic therapy for choroidal neovascular membrane secondary to optic nerve drusen.

The authors describe the use of photodynamic therapy with verteporfin for subfoveal choroidal neovascular membrane secondary to optic nerve drusen. A 28-year-old woman had a peripapillary choroidal neovascular membrane secondary to optic nerve drusen with significant metamorphopsia. Photodynamic therapy using verteporfin was performed. Visual acuity improved to 20/20 with resolution of metamorphopsia and absence of leakage on fluorescein angiography a few weeks after verteporfin therapy. The patient's condition remained stable for 16 months with 20/20 vision. Photodynamic therapy with verteporfin may be a useful treatment option in patients with choroidal neovascular membranes secondary to optic nerve drusen.
