Relationship between electroretinogram records and clinical signs in patients with various stages of primary open-angle glaucoma

Journal of Ophthalmology, 2016
Introduction. Lately, a much attention has been paid to studying the retina in patients with primary open angle glaucoma (POAG). The essence of the process has been reported to be an accelerated death of ganglion cells in the retina and retinal axons ...

A hypothermia mimetic molecule (zr17-2) reduces ganglion cell death, gliosis, and electroretinogram distortion in male rats subjected to perinatal asphyxia

Frontiers in Pharmacology, 2023
Introduction: Perinatal asphyxia (PA) represents a major problem in perinatology and may cause visual losses, including blindness. We, and others, have shown that hypothermia prevents retinal symptoms associated to PA.
