Multifocal electroretinogram changes in patients with retinal vein occlusion

Delta Journal of Ophthalmology, 2020
Background Retinal vein occlusion (RVO) is one of the most common vascular retinal disorders that lead to macular edema. There is often discrepancy between visual prognosis and optical coherence tomography (OCT) changes.

Relationship between optical coherence tomography and electrophysiology of the visual pathway in non-optic neuritis eyes of multiple sclerosis patients. [PDF]

PLoS ONE, 2014
PURPOSE: Loss of retinal ganglion cells in in non-optic neuritis eyes of Multiple Sclerosis patients (MS-NON) has recently been demonstrated. However, the pathological basis of this loss at present is not clear.

Rare occult macular dystrophy with a pathogenic variant in the RP1L1 gene in a patient of Swiss descent

American Journal of Ophthalmology Case Reports, 2022
Purpose: We report a first case of bilateral occult macular dystrophy (OMD) with a c.133C>T (p.Arg45Trp) pathogenic variant in the retinitis pigmentosa 1-like 1 (RP1L1) gene in a patient of Caucasian Swiss decent.
