Chromatic pupillometry for assessment functional rod and cone patterns in Usher syndrome patients

Acta Ophthalmologica, 2014
AbstractPurpose The aim of the study was to characterize the functional rod and cone patterns using chromatic pupillometry in Usher syndrome patients.Methods Prospective case series study enrolled 45 Usher syndrome patients. All patients underwent in‐depth phenotypic examination.

Chromatic pupillometry findings in attention deficit hyperactivity disorder: Sex differences

Ophthalmic and Physiological Optics
Abstract Introduction Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder with a complex aetiology, involving dysfunctions in serotonergic, noradrenergic and dopaminergic neural pathways, alongside disturbances in the autonomic nervous system.

Full-field Chromatic Pupillometry for the Assessment of the Postillumination Pupil Response Driven by Melanopsin-Containing Retinal Ganglion Cells

Investigative Opthalmology & Visual Science, 2014
The postillumination pupil response (PIPR) is produced by intrinsically photosensitive retinal ganglion cells (ipRGCs). We aimed to refine the testing conditions for PIPR by investigating whether a greater PIPR can be induced using full-field light stimuli of shorter duration and lower intensity than that produced by existing protocols that use central-

Chromatic multifocal pupillometry for objective perimetry in patients with Best's vitelliform macular dystrophy (Conference Presentation)

Ophthalmic Technologies XXVII, 2017
Purpose: Objective pupilloperimetry in healthy subjects and patients with Best’s Vitelliform Macular Dystrophy using a chromatic multifocal pupillometer (CMP). Methods: A CMP (Accutome Inc) was used to record pupillary responses (PR) of 17 healthy subjects and 5 Best’s patients.

Chromatic Pupillometry for Screening and Monitoring of Retinitis Pigmentosa

2019
Early diagnosis of Inherited Retinal Diseases, such as Retinitis Pigmentosa (RP) is challenging in pediatric patients, because their diagnosis mainly relies on relatively invasive tests. We conducted a pilot study to evaluate the usefulness of chromatic pupillometry in RP.

Chromatic pupillometry as highly sensitive testing method of photoreceptor function in retinal dystrophies

Acta Ophthalmologica, 2012
AbstractPurpose Objective methods for the characterization of photosensitive cells are highly needed in patients with retinal dystrophies. The pupil light reflex is driven by rod, cone, and intrinsic photosensitive retinal ganglion cell (ipRGC) input.

Toward a Novel Medical Device Based on Chromatic Pupillometry for Screening and Monitoring of Inherited Ocular Disease: A Pilot Study

2018
Chromatic pupillometry is a relatively novel research tool for retinal function evaluation and may be an appropriate and easier way to diagnose and monitor inherited retinal diseases in paediatric population. Nevertheless, although the method is clinically feasible in paediatric populations, as shown by several non-ocular studies, only few studies, on ...
