Retinal Angiomatous Proliferation Reactivation 6 Months after High-Dose Intravitreal Acetonide Triamcinolone and Photodynamic Therapy

Abstract

Purpose To describe the incidence of retinal angiomatous proliferation (RAP) reactivation after combined treatment with a high-dose intravitreal triamcinolone acetonide (IVTA) and photodynamic therapy (PDT) at 1-year follow-up. Methods All patients had undergone a full ophthalmic examination. High-dose IVTA (20 mg) was injected via pars plana. Four to 7 days later, PDT was delivered. Results Fourteen eyes of 13 patients were included. Eight lesions (57%) reopened and needed retreatment with combined therapy at 6 months follow-up. At 1-year follow up, the lesion was obliterated in nine cases (64.2%) and best-corrected visual acuity improved from 0.87 logMar (range, 0.7–1) to 0.79 logMar (range, 0.5–1). Conclusions Combined therapy using high-dose IVTA and PDT is beneficial in stabilizing RAP. However, a high incidence of RAP reactivation has been observed at 6 months, even with a high-dose IVTA injection.
