Abstract

Objectives: To correlate clinical and histopathologic features of an eye with retinal angiomatous proliferation (RAP) secondary to age-related macular degeneration and to investigate the expression of von Willebrand factor (VWF) and vascular endothelial growth factor (VEGF) in this condition. Methods: Histopathologic features from serial sections through the globe of an 87-year-old woman with RAP were studied and compared with fluorescein angiography and color fundus photographs obtained 4 months before death. Commercially available antibodies were used to detect expression of VWF and VEGF in tissue sections. Results: The pathologic correlate of RAP was a circumscribed intraretinal angiomatous complex within the outer part of the neurosensory retina overlying a large pigment epithelial detachment. There were no breaks in the Bruch membrane. No choroidal neovascularization was present. Endothelial cells within the RAP lesion immunostained positively forVWFand VEGF. The Bruch membrane expressed VWF adjacent to the RAP. Conclusions: Fundus examination and fluorescein angiography images of RAP in a patient with age-related macular degeneration correlated histopathologically with a neovascular intraretinal angiomatous complex, without the presence of sub-retinal pigment epithelial neovascularization. Immunostaining demonstrated that RAP expresses VWF and VEGF.
