Abstract

Both solar and laser sources may induce punctate foveal retinal damage. Unprotected viewing of the sun or bright blue sky represent potential solar radiation causes of photic maculopathy that may induce punctate foveal damage. Laser induced macular retinal damage is another more recent kind of photic maculopathy. Most documented cases of laser photic maculopathy have involved acute laser exposure generally from Q-switched visible or nonvisible near IR laser systems. In our comparison of these types of photic maculopathies, we have employed conventional as well as spectral and confocal scanning laser ophthalomoscopy to evaluate the depth of the photic maculopathy. Functionally, we have observed a tritan color vision loss present in nearly all photic maculopathies.
