The Loss of Light Energy in Retina and Choroid

Arch Ophthalmol. 1960;64(4):606-615. doi:10.1001/archopht.1960.01840010608020

Introduction  Flash blindness and chorioretinal burns have attracted increasing attention during the past decade because of the eye hazard from nuclear weapons1-6 and because of the significant development of light coagulation of the retina as a clinical tool in ophthalmology.7-9 Data on the spectral absorption characteristics of the ocular fundus are needed for realistic evaluation of the retinal burn capabilities of nuclear weapons and for a more thorough exploitation of the clinical uses of light coagulation. This problem is not related directly to visual sensitivity, since only a small proportion of the energy incident on the retina is absorbed by the retinal layers anterior to the pigment epithelium. Thermal lesions result from selected absorption in the pigment epithelium and in the vascularized and pigmented choroid.Previous studies on the transmission of light through the ocular media of the rabbit eye10 suggested that the same technique might be
