The clinical course of a patient treated with multiple sessions of photodynamic therapy (PDT) with verteporfin for subretinal neovascularization secondary to bilateral idiopathic acquired juxtafoveolar telangiectasis is described. The patient presented with subfoveal subretinal neovascularization in one eye secondary to bilateral idiopathic acquired juxtafoveolar telangiectasis. The visual acuity improved from 5/40 to 20/60 and fluorescein angiography documented near-complete closure of the subretinal neovascularization within 2 weeks following the initial session of PDT. The visual acuity decreased to 20/200 and fluorescein angiography documented reperfusion of the neovascular membrane 6 weeks later. Four additional sessions of PDT were administered during the next 13 months with similar results. This case indicates that PDT for subretinal neovascularization due to bilateral idiopathic acquired juxtafoveolar telangiectasis may achieve partial short-term neovascular membrane closure and improvement in visual acuity.
