[Show abstract][Hide abstract] ABSTRACT: This study was designed to evaluate the frequency and nature of neovascularization in age-related macular degeneration (ARMD) utilizing the combination of digital imaging techniques, fluorescein angiography (FA), indocyanine green (ICG) angiography, and optical coherence tomography (OCT).
A complete clinical examination was performed on 100 eyes of 93 consecutive newly diagnosed patients with neovascular ARMD. Digital fluorescein angiography, ICG angiography, and OCT were also used in evaluating those patients. Comparison of the imaging techniques to determine their value in studying the nature of the lesions.
On the basis of existing fluorescein standards, 15 eyes were diagnosed with classic choroidal neovascularization (CNV), 15 with minimally classic CNV, and 70 with occult CNV. ICG angiography was superior for detecting the active vascular component in polypoidal CNV (16 eyes) and retinal angiomatous proliferation (14 eyes). OCT was more sensitive than FA for determining the presence of cystoid macular edema evident in the vast majority of eyes with retinal angiomatous proliferation (RAP).
These results suggest that FA, ICG angiography, and OCT, when used in combination, will assist clinicians in best determining the precise nature of the neovascular process in ARMD.

[Show abstract][Hide abstract] ABSTRACT: To study sequenced combined therapy using intravitreal triamcinolone acetonide followed by photodynamic therapy for the treatment of retinal angiomatous proliferation.
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.
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.
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.
