Foveola

The foveola is located within a region called the macula, a yellowish, cone photo receptor filled portion of the human retina. The foveola is approximately 0.35 mm in diameter and lies in the center of the fovea and contains only cone cells, and a cone-shaped zone of Müller cells. In this region the cone receptors are found to be longer, slimmer and more densely packed than anywhere else in the retina, thus allowing that region to have the potential to have the highest visual acuity in the eye.Schematic diagram of the macula lutea of the retina, showing perifovea, parafovea, fovea, and clinical maculaTime-Domain OCT of the macular area of a retina at 800 nm, axial resolution 3 µmSpectral-Domain OCT macula cross-section scan.macula histology (OCT)A fundus photograph showing the macula as a spot to the left.
