Perifovea

Perifovea is a region in the retina that circumscribes the parafovea and fovea and is a part of the macula lutea.^[1] The perifovea is a belt that covers a 10° radius around the fovea and is 1.5 mm wide.^[2][3] The perifovea ends when the Henle's fiber layer disappears and the ganglion cells are one-layered.^[4]
