Evaluation of Objective Perimetry Using Chromatic Multifocal Pupillometer
Objective Perimetry in Normal Subjects,Glaucoma Patients and Retinal Dystrophy Patients
Source: ClinicalTrials.gov · Last updated 25 Apr 2024 · Not updated for over 12 months - ask the site whether it is still open
Brief summary (registry, in English)
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.
