retinal densitometry

a method of measuring the absorptance characteristics of retinal photopigments. A light that is shone into the eye travels through the retina, is reflected back out of the eye by tissues behind the retina, and is measured. The light that emerges is compared to the original light to determine how much was absorbed.
