The macular region of eye is made up of the umbo, foveola, fovea, parafoveal and perifoveal.
- Umbo is placed at center of fovea's foveola and the foveola is located at center of its fovea.
- The fovea contains the highest concentration of cone cells
- Located in the middle of the fovea, the foveola is roughly 0.35 millimeters in diameter and consists of solely cone cells and a cone-shaped region of Müller cells.
- It has been shown that there are more cone receptors in the foveola than everywhere else in the retina, allowing it to have the best visual clarity.
- Because the cones do not fully form until many months after birth, a newborn's central focus is imperfect.
