Photodynamic therapy of subfoveal neovascular membrane in type 2A idiopathic juxtafoveolar retinal telangiectasis.

PURPOSE: To evaluate the effect of photodynamic therapy on subfoveal neovascular membrane related to type 2A idiopathic juxtafoveolar retinal telangiectasia. DESIGN: Interventional case series. METHODS: Retrospective review of four eyes of four patients who underwent photodynamic therapy for subfoveal neovascular membrane secondary to idiopathic juxtafoveolar retinal telangiectasia. Ocular photodynamic therapy with verteporfin was performed in all cases using standard protocols. Results are given in terms of final visual acuity and neovascular membrane activity based on clinical examination, fluorescein and indocyanin green angiography, and, in two cases, optical coherence tomography. RESULTS: Baseline visual acuity of 20/30 and 20/40 (x2) was maintained in three patients after one, two, and three sessions of photodynamic therapy respectively, and a follow-up of 23, 21, and 9 months. Leakage specific to the subfoveal neovascular membrane ceased on the fluorescein angiography. In the other patient, the final vision decreased from 20/50 to 20/200 after four sessions of photodynamic therapy and a follow-up of 14 months. Although there was still mild persistent leakage on the fluorescein angiography, neovascular membrane size was unchanged, and no subretinal fluid was demonstrated on optical coherence tomography. CONCLUSIONS: Data from this case series suggest that photodynamic therapy may be effective in managing subfoveal neovascular membrane associated with idiopathic juxtafoveolar retinal telangiectasia, which usually carries a poor visual prognosis. Prospective study is required to confirm the beneficial effect of this treatment.[1]
