Optogenetics research uses medium-wavelength cone opsin to re-engineer retinal ganglion cells for retinitis pigmentosa

Researchers at the University of Berkeley have reported that the vertebrate medium wavelength cone opsin (MW-opsin) may be used to overcomes limitations to support vision in dim light in a mouse model for retinitis pigmentosa (RP).  The study will be used to develop optogenetic therapy to overcome downstream retinal neurons where rod photoreceptors may have […]

Microvascular retinal changes between Alzheimer’s patients and control participants

An Italian research team based in Milan has reported that functional and morphological changes in the retinal vasculature can be identified within Alzheimer’s disease (AD) or mild cognitive impairment (MCI) participants.  The study, published in Scientific Reports ((2019) DOI:10.1038/s41598-018-37271-6), stated that “we demonstrated that vascular changes characterize these disorders and that such alterations are mainly […]

Study suggests that transferrin supplementation may be used as an adjunctive therapy to surgery for patients with retinal degeneration

A Paris-based research report suggests that transferrin, the iron-binding serum protein, could be useful to help to treat patients with retinal detachment (RD).  Human studies indicate that ocular fluids from patients with rhegmatogenous retinal detachment (RRD) shows that iron increases with detachment duration and correlates with poor visual recovery.  While there is clear progress made […]
