The measurement of ocular transmittance and irradiation distribution in argon laser irradiated rabbit eyes.

Abstract

The transmittance of the ocular media has been measured in vivo in rabbit eyes using an argon laser light source and microthermocouple sensor. The intensity profiles at the cornea and retina were measured with the thermocouple and the ratio of the power associated with the intensity profiles indicated the fraction of light power reaching the retina. Measurements from 10 rabbits indicated a transmittance coefficient of 0.85 for wavelengths between 488 and 514.5 nm.
