Abstract
Age-related macular degeneration (AMD) is the leading cause of irreversible severe visual loss in the United States and Europe in people over 50 years of age [1]. Retinal angiomatous proliferation (RAP) is a distinct subgroup of AMD characterized by the origination of new vessels from the retina or from the choroid with early formation of a retinal choroidal anastomosis [2].
The diagnosis of RAP is similar with the diagnosis of the AMD, but retinal pigment epithelial detachment, exudates and superficial hemorrhages are more common in RAP. At present, different imaging modalities are used in the diagnosis of AMD.
The imaging methods fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are widely used for diagnosis and follow-up of patients with this disease. Optical coherence tomography angiography (OCTA) is a recent noninvasive imaging tool capable of providing the retinal and choroidal vasculature information using split-spectrum amplitudedecorrelation angiography software without the need for dye injection.
We describe the case of a 63-year-old female with unilateral RAP, which was diagnosed and followed-up by using OCTA and treated successfully with intravitreal anti-VEGF injection. In conclusion, we found that OCTA is a useful, safe, repeatable diagnostic tool for evaluating macular disorders.
