Randomized trial measures photoreceptor density in human retinas, highlighting individual variability.

The aim is to measure the spatial density of cones and rods in human retinas and analyze individual differences.
Measured density of cones and rods in eight whole-mounted human retinas from seven individuals aged 27-44 years.
Constructed maps of photoreceptor density and analyzed variability between individuals.
Assessed cone and rod distributions concerning eccentricity and retinal regions.
Average human retina contains 4.6 million cones with peak foveal density of 199,000 cones/mm2 (100,000-324,000 cones/mm2).
Average human retina has 92 million rods, with density highest along an elliptical ring in superior retina.
Individual variability in photoreceptor density is highest near the fovea and consistent for both cones and rods.

Curcio et al. (1990) studied this question.
