RECRUITINGOBSERVATIONAL
Evaluation of Objective Perimetry Using Chromatic Multifocal Pupillometer
Objective Perimetry in Normal Subjects,Glaucoma Patients and Retinal Dystrophy Patients
About This Trial
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.

10. Sphincter damage due to trauma (tears of sphincter or diffuse damage to muscle).
11. Sphincter damage due to Herpes Zoster Uveitis.
12. Sphincter damage due to high intraocular pressure.
13. Iris tumor or cyst.
14. Ectropion uvae.
15. Adie's pupil.
16. Third nerve aberrant regeneration of the iris sphincter.
17. RP patients with Optic neuropathy with the potential of producing a positive RAPD (Relative Afferent Pupillary Defect).
18. Chronic use of myotics or mydriatics.
