In a healthy eye, are there capillaries in the center of the fovea?

• A. Yes
• B. No
• C. Sometimes
• D. Unknown

Answer: (B)

The center of the fovea is avascular on purpose. This tiny area, the foveal avascular zone, is devoid of retinal capillaries to minimize light obstruction and scattering, allowing the densely packed cone photoreceptors to capture light with maximal precision for high-acuity vision. While the surrounding parafoveal retina has capillaries, the very center lacks them so that light can pass directly to the cones and the outer retina receives its blood supply from the underlying choroid (via the choriocapillaris). In a healthy eye, there are no capillaries right at the center of the fovea. If abnormalities develop, such as neovascularization, capillaries can appear abnormally, but that is not the normal state.
