Agonistic autoantibodies against ß2-adrenergic receptor influence retinal microcirculation in glaucoma suspects and patients. [PDF]

PLoS ONE, 2021
PurposeAgonistic β2-adrenergic receptor autoantibodies (β2-agAAb) have been observed in sera of patients with ocular hypertension and open-angle glaucoma (OAG).

Retinal peripapillary nerve fiber and retinal ganglion cell layer thickening preceed atrophy in children and teenagers with optic disc drusen [PDF]

Scientific Reports
In adults, optic disc drusen (ODD) are linked to thinning of the retinal ganglion cell layer (rGCL) and peripapillary retinal nerve fibre layer (pRNFL), but stage-specific pediatric changes remain unclear.

Examining the concordance of retinal ganglion cell counts generated using measures of structure and function. [PDF]

Ophthalmic Physiol Opt, 2022
Abstract Purpose There are several indirect methods used to estimate retinal ganglion cell (RGC) count in an individual eye, but there is limited information as to the agreement between these methods. In this work, RGC receptive field (RGC‐RF) count underlying a spot stimulus (0.43°, Goldmann III) was calculated and compared using three different ...

Optical Coherence Tomography Parameters in Morbidly Obese Patients Who Underwent Laparoscopic Sleeve Gastrectomy

Journal of Ophthalmology, 2016
Purpose. To investigate changes in optical coherence tomography parameters in morbidly obese patients who had undergone laparoscopic sleeve gastrectomy (LSG). Methods. A total of 41 eyes of 41 morbidly obese patients (BMI ≥ 40) who had undergone LSG were

TRPV4 controls circadian and pathological ocular hypertension. [PDF]

J Physiol
Abstract figure legend Transient receptor potential vanilloid isoform 4 (TRPV4) maintains ocular hypertension under physiological and pathological conditions. Left: night‐time. The nocturnal phase of the circadian rhythm elevates intraocular pressure (IOP) to ∼22 mmHg in a TRPV4‐dependent manner.

Assessment of Retinal Nerve Fiber Layer (RNFL) and Retinal Ganglion Cell Layer (RGCL) Thickness in Radiologically Isolated Syndrome (RIS)

Archives of Neuroscience, 2023
Background: Three-thirds of people with radiologically isolated syndrome (RIS) develop multiple sclerosis (MS) within five years following their first brain magnetic resonance imaging (MRI). Subclinical applications of optical coherence tomography (OCT) include measuring the thickness of different retinal layers and monitoring the progression of visual

Investigating the linkage between mesopic spatial summation and variations in retinal ganglion cell density across the central visual field

Ophthalmic and Physiological Optics, Volume 43, Issue 5, Page 1179-1189, September 2023., 2023
Abstract Purpose The relationship between perimetric stimulus area and Ricco's area (RA) determines measured thresholds and the sensitivity of perimetry to retinal disease. The nature of this relationship, in addition to effect of retinal ganglion cell (RGC) number on this, is currently unknown for the adaptation conditions of mesopic microperimetry ...

Temporal summation in myopia and its implications for the investigation of glaucoma

Ophthalmic and Physiological Optics, Volume 43, Issue 4, Page 788-797, July 2023., 2023
Abstract Purpose We have previously demonstrated the upper limit of complete spatial summation (Ricco's area) to increase in non‐pathological axial myopia compared to non‐myopic controls. This study sought to investigate whether temporal summation is also altered in axial myopia to determine if this aspect of visual function, like in glaucoma, is ...
