Retinal angiomatous proliferation.

This is a variant of age-related macular degeneration in which dilated intraretinal capillaries are observed in the parafoveal area, which are believed to communicate with an underlying choroidal neovascular membrane (CNV). They are usually treated in the same way as other CNV’s with anti vascular endothelial growth factor inhibitors. A recent study has shown that these lesions may respond to a combination of intravitreal steroid in the form of triamcinolone (4mg) and micropulsed laser photocoagulation to the retinal lesions.
