Abstract

Abstract: : Purpose:To assess the connection between intraretinal angiomatous proliferation (RAP) and choroidal circulation in RCA. Methods:124 eyes of 100 patients (mean age: 79 ± 5; 24% M; 76% F)affected by RCA underwent fluorescein and indocyanine green angiography (FA, ICGA); 97 eyes (78.2%) have been studied by dynamic indocyanine green angiography (Scanning Laser Ophthalmoscope – SLO). Furthermore, 64 eyes (51.6%) have been examined by Optical Coherence Tomography (OCT). Results:In 24% of the cases studied, RAP was bilateral. Drusen were present in 78% of the cases, Serous Neuroepithelial Detachment (SND) were observed in 91% of the cases, while Pigment Epithelium Detachment (PED) represented 47% of the cases. Only in few cases FAG and ICGA revealed angiographic retinal images that might be referred to the presence of an anastomosis between RAP and choroidal circulation Conclusion:Results suggest that intraretinal angiomatous proliferation is not usually connected with choroidal circulation, also at advanced stage. This confirms the existence of two clinical types of exhudative age-related macular degeneration (ARMD). In the first one the vascular complex has an intraretinal origin, while in the second one it has a choroidal origin.
