A clinical case is described. A double macular fovea was found in patient S., 11 y. o., during optical coherence tomography. The thickness of the retina in the center of the true macular fovea was 208 µm, in the center of the pseudomacular fovea – 242 µm. Foveas were located in the same horizontal section. The presence and absence of appropriate retinal layers indicates a real doubling of the fovea. Two distinct avascular pigmented rounded zones were observed on the fundus in the central part of the retina. High amplitude of multifocal ERG was revealed in pseudofovea. This feature of the retinal central zone structure may be due to malformation of the retina in parafoveal region.

Key words: optical coherence tomography, retina, fovea.
