Evaluation of Objective Perimetry Using Chromatic Multifocal Pupillometer
Objective perimetry can better monitor visual field defects in retinal dystrophy and Glaucoma patients than conventional subjective perimetry. The PLR ( Pupil Light Reflex to short and long wavelength stimuli should be significantly lower compared to healthy participants in areas of visual field defects in retinal dystrophy and Glaucoma patients.
