BACKGROUND: Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD) with particularly bad prognosis. Diverse treatment modalities are performed.
PATIENTS AND METHODS: This is a retrospective review on the treatment results of 41 consecutive patients from 1/2003 to 12/2005 with RAP stage 1-3 (Yannuzzi classification), who were treated with laser photocoagulation, photodynamic therapy (PDT) and intravitreal injection of triamcinolone acetonide (IVT). Follow-up was 12 months minimally.
RESULTS: In RAP stage I complete closure of the vascular lesion in 14 / 22 eyes was achieved by 1.2 +/- 0.5 sessions of laser photocoagulation (4 x combined with IVT) and in 3/14 eyes with photodynamic therapy (2 +/- 0.5 sessions). In RAP stage II closure of the lesion was achieved by 3.2 +/- 0.6 sessions of photodynamic therapy in 6/14 eyes (4 x combined with IVT). In RAP stage III closure of the lesion was achieved by 3.2 +/- 0.4 sessions of photodynamic therapy in 0 / 5 eyes (3 x combined with IVT). A rip of the retinal pigment epithelium was observed in 2/14 eyes of RAP stage II and 2/5 eyes of RAP stage III. Visual acuity improved in 9/17 eyes with occlusion of RAP stage I. Without closure of the vascular lesion all eyes got legally blind (visual acuity 1/50 or less).
CONCLUSIONS: Early detection and subsequent direct treatment of RAP stage I in AMD is recommended. In advanced stages anatomical closure of the vascular complex is rarely achieved and the risk is improved for development of tears in the retinal pigment epithelium and getting legally blind.
