Which macular region contains the largest number of ganglion cells?

• A. Foveola
• B. Parafovea
• C. Fovea
• D. Perifovea

Answer: (B)

The macula’s cells aren’t distributed evenly; the inner retinal layers build up most densely in the parafovea. The very center region, the foveola, is a cone-dense pit with minimal or no ganglion cells to optimize light delivery to cones. As you move slightly away from the fovea into the parafovea, the ganglion cell layer thickens and reaches its peak cell count there, providing high-resolution processing for central vision. Beyond that, in the perifovea, ganglion cell density diminishes again as you move toward the peripheral retina. So the area around the fovea, the parafovea, contains the largest number of ganglion cells.
