Effects of Indirect Pupillary Light Reflex Stimulation With Colored Light on Corneal Specular Microscopy Performance in Dogs

open access: yesVeterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To compare the effects of indirect pupillary light reflex (PLR) stimulation using differently colored lights on corneal specular microscopy performance in dogs and to determine the influence of pupil diameter. Animals Studied 20 client‐owned dogs (38 eyes) with healthy corneas.

Relationship between Abnormalities in Neurophysiological Processes in Central and Peripheral Regions of the Retina and Clinical Parameters in Patients with Different Stages of Primary Open-Angle Glaucoma

open access: yesGalician Medical Journal, 2016
Primary glaucoma is a disease causing the greatest number of vision-related problems. Accelerated death of retinal ganglion cells and their axons which comprise the optic nerve as well as their involvement in the pathological process of neuroglia which ...

Comparison of Pattern Electroretinography and Optical Coherence Tomography Parameters in Patients with Primary Open-Angle Glaucoma and Ocular Hypertension

open access: yes, 2015
Objectives: To investigate the correlation of visual field (VF), pattern electroretinography (PERG) and Fourier domain optical coherence tomography (FD-OCT) results in patients with ocular hypertension (OHT) and early primary open-angle glaucoma (POAG).

Cone Electroretinography by Flicker [PDF]

open access: yesNature, 1951
IT is generally assumed that the b-wave of the human retinal action potential is due to the stimulation of the rods. With an intensity of 2,000 lux, the b-waves fuse at a frequency of about 20 flashes per second. At lower intensities the fusion frequency in our experiments decreased.

Serotonin Signaling Pathway Modulation Affects Retinal Neuron Survival in Experimental Model of Retinal Ischemia

open access: yesLife
Serotonin is a key neurotransmitter involved in visual processing. Selective serotonin reuptake inhibitors (SSRIs), such as Escitalopram, enhance serotonergic transmission and exert neuroprotective effects.

Electroretinography in the Collared Scops Owl (Otus lettia)

open access: yesVeterinary Sciences
Electroretinography (ERG) is a non-invasive technique used to assess retinal function via electrical responses to light stimuli. We established baseline ERG parameters and a standardized recording protocol for collared scops owls (Otus lettia).

Functional implications of short-term retinal detachment in porcine eyes: study by multifocal electroretinography.

open access: yes, 2008
The aim of the study was to determine the type and magnitude of detectable changes in pig multifocal electroretinography (mfERG) induced by the vitreoretinal surgical procedures necessary to gain access to the subretinal ...

Atypical Retinitis Pigmentosa With Systemic Features in Bardet–Biedl Syndrome

open access: yesClinical Case Reports
Recognition of systemic features such as polydactyly in a patient with retinitis pigmentosa is crucial for early diagnosis of Bardet–Biedl syndrome. Mild non‐pitting swelling of the hands—an incidental, non‐classical finding—was also noted, emphasizing ...

Congenital stationary night blindness: an update and review of the disease spectrum and genotype-phenotype correlations

open access: yesYanke Xuebao
Congenital Stationary Night Blindness (CSNB) represents a group of highly heterogeneous inherited retinal diseases(IRDs) primarily caused by impaired signal transmission between photoreceptor cells and bipolar cells in the retina.
