Stem-cell derived retina found to improve vision in monkeys with RP

Researchers at the RIKEN Institute in Japan have succeeded in growing human embryonic stem cell-derived retina (hESC-retina) and transplanting that tissue into the retinas of rhesus monkeys with Retinitis Pigmentosa (RP). Three weeks after the treatment, visual tests on two of the monkeys found their vision had improved. In the study, published in the journal PNAS,

A gene therapy platform for macular degeneration patients

Physics researchers at The University of Texas at Arlington have developed a new platform that uses ultrafast near-infrared lasers to deliver gene therapy to damaged areas of the retina to enable vision restoration in patients with photo-degenerative diseases such as macular degeneration. Samarenda Mohanty, assistant professor of physics and head of UTA’s Biophysics and Physiology

PRP for diabetic retinopathy

Ranibizumab Found Effective Against Diabetic Retinopathy

In a randomized clinical trial conducted by DRCR.net of more than 300 participants, researchers have found that ranibizumab is an effective alternative to Panretinal photocoagulation (PRP) (laser therapy for treating diabetic retinopathy). Results also show that the drug therapy carries fewer side effects than the currently used laser treatment.
