The diagnostic accuracy of chromatic pupillary light responses in diseases of the outer and inner retina.

Purpose: To compare the chromatic pupillary light responses (PLR) in healthy subjects with those from patients with diseases of the outer or inner retina under various stimulus conditions, and to ascertain the parameters required to optimally distinguish between disease and control groups.

Methods: Fifteen patients with retinitis pigmentosa (RP), 19 patients with optic nerve disease (ON), and 16 healthy subjects were enrolled in this prospective study. ON included optic neuritis (NNO) and non-arteritic anterior ischemic optic neuropathy (NAION).
