Chromatic pupillometry for the characterization of the pupillary light reflex in Octodon degus

Experimental Eye Research, 2020
The common degu (Octodon degus) is an emerging model in biomedical science research due to its longevity and propensity to develop human-like conditions. However, there is a lack of standardized techniques for this non-traditional laboratory animal.

ORÁO: RESTful Cloud-Based Ophthalmologic Medical Record for Chromatic Pupillometry

IFMBE Proceedings, 2019
Chromatic pupillometry represents a pioneering approach to the evaluation of inherited ocular diseases in childhood and a pilot study has been designed to evaluate its clinical utility. The physicians involved in the project belong to two different University centres: the data they gather must be collected in an electronic medical record reachable via ...

Chromatic Pupillometry – a New Technique for Assessing Function in Glaucoma?

Klinische Monatsblätter für Augenheilkunde, 2023
AbstractChromatic pupillometry allows quantification of photoreceptor-driven (extrinsic) and melanopsin-driven (intrinsic) responses of the intrinsic-photosensitive retinal ganglion cells (ipRGCs). This small subpopulation of retinal ganglion cells is also affected by glaucoma, making chromatic pupillometry a potential diagnostic tool.

Chromatic Pupillometry in Patients with Retinitis Pigmentosa

Ophthalmology, 2011
To evaluate the chromatic pupillary response as a means of assessing outer and inner retinal function in patients with retinitis pigmentosa (RP).Evaluation of diagnostic technology.Thirty-two patients with RP and visual loss and 43 normal subjects.Patients were tested with a chromatic pupillometer using red and blue lights (1, 10, and 100 cd/m(2)), and

A collaborative RESTful cloud-based tool for management of chromatic pupillometry in a clinical trial

Health and Technology, 2019
Chromatic Pupillometry represents a novel approach for the assessment of Inherited Retinal Diseases. A multi-centric pilot study with a sample of 40 paediatric patients has been designed, involving physicians and engineers. In this paper, the Electronic Medical Record, named ORAO and specifically developed to collect ophthalmologic and pupillometric ...

Handheld chromatic pupillometry can reliably detect functional glaucomatous damage in eyes with high myopia

British Journal of Ophthalmology, 2022
Background/aims To assess pupillary light responses (PLRs) in eyes with high myopia (HM) and evaluate the ability of handheld chromatic pupillometry (HCP) to identify glaucomatous functional loss in eyes with HM.

Chromatic Pupillometry Dissects Function of the Three Different Light-Sensitive Retinal Cell Populations in RPE65 Deficiency

Investigative Opthalmology & Visual Science, 2012
The aim of the study was to objectively characterize the function of rods, cones, and intrinsic photosensitive retinal ganglion cells (ipRGCs) in patients with RPE65 mutations by using two published protocols for chromatic pupillometry, and to correlate the data with the clinical phenotype.The study group comprised 11 patients with RPE65 mutations, and

Test-Retest Reliability of Hemifield, Central-Field, and Full-Field Chromatic Pupillometry for Assessing the Function of Melanopsin-Containing Retinal Ganglion Cells

Investigative Ophthalmology and Visual Science, 2015
We evaluated the test-retest reliability of current methods of inducing the melanopsin-driven postillumination pupil response (PIPR) under hemifield, central-field, and full-field stimulation conditions.Pupil response was recorded with an eye tracker in 10 visually normal participants.

Isoluminant chromatic pupillometry an evaluation of peak velocity contraction in pseudophakic eyes

AIP Conference Proceedings, 2012
To describe a way to evaluate the peak velocity of contraction (PVC) and Time of peak velocity contraction (TPVC), of pupillary responses at two isoluminant chromatic stimuli (Blue and Red) with a luminance level of 9 cd/m2 in patients with multifocal intraocular lens (MIOL) implant by means of high speed video-oculography (HSV) and digital eye image ...
