- Original description
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.Read full original descriptionShow less
Objective Perimetry in Normal Subjects,Glaucoma Patients and Retinal Dystrophy Patients
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.
