Flicker electroretinogram in newborn infants

The purpose of the study was to develop and validate a flicker electroretinogram (ERG) protocol through closed eyelids in term-born neonates as a potential tool for assessing preterm infants at risk of developing retinopathy of prematurity. Healthy term-born neonates were included and measurable results could be obtained for all babies with an intensity of 30cd-s/m². […]

Photopic negative response recorded with RETeval system in eyes with optic nerve disorders

The purpose of this study was to determine whether PhNRs (Photopic negative response) recorded with the RETeval system and circumpapillary retinal nerve fiber layer thickness (cpRNFLT) are significantly correlated in eyes with optic nerve disorders. Patients with optic nerve disorders had significantly smaller PhNRs compared to the control subjects and the ROC analysis indicated that […]

Early Changes in Photopic Negative Response in Eyes with Glaucoma

PHnR glaucoma results

In this study, the PhNR of the RETeval was compared following glaucoma filtration surgery in patients with and without choroidal detachment after surgery. A functional improvement of the ganglion cell function (PhNR measurement) was observed after surgery. The presence of choroidal detachment appears to arrest the improvement of the ganglion cell function and less improvement […]
