Objective To study sequenced combined therapy using intravitreal triamcinolone acetonide followed by photodynamic therapy for the treatment of retinal angiomatous proliferation.
Methods Patients newly diagnosed as having retinal angiomatous proliferation underwent intravitreal triamcinolone injection to reduce intraretinal and subretinal exudation, followed 7 to 14 days later by indocyanine green angiography–guided photodynamic therapy with verteporfin. Complete ocular examination, fluorescein angiography, indocyanine green angiography, and optical coherence tomography were performed at baseline and at standard intervals thereafter.
Results Twenty-seven eyes of 26 patients underwent this sequenced combined treatment and were followed up for 12 months. The triamcinolone injection reduced the cystoid edema before photodynamic therapy. Complete resolution of the angiographic leakage was achieved in 89% of eyes. Visual acuity improved in 37% and was stable in 52% of eyes. Eight eyes developed recurrent leakage after 3 to 11 months. Complete resolution of leakage was observed after subsequent treatment.
Conclusions This sequenced combined treatment in patients with retinal angiomatous proliferation was effective in reducing or eliminating the edema, achieving rapid regression of neovascularization, and stabilizing or improving visual acuity. To our knowledge, no study to date has achieved such promising results in the management of retinal angiomatous proliferation. A randomized clinical trial is under way to compare sequential and simultaneous combined therapy.
