A trio of eyeglasses using revolutionary prism techniques could open up a whole new field of view for patients with hemianopia. The three designs – yoked prisms in a carrier lens, a bi-part double Fresnel prism, and the mirror-based periscopic prisms – were showcased in the journal Optometry and Vision Science. Lead researcher and Harvard Medical School ophthalmology professor, Dr Eli Peli, told …

Solving Three Major Age-related Eye Conditions in One Go
Vascular endothelial growth factor A (VEGF-A) is looking like more of an optical troublemaker than ever before – as well as its link with wet age-related macular degeneration (AMD), it also might be causing dry AMD and even age-related cataracts. Therefore, Massachusetts General Hospital researcher and paper author, Dr Alexander Marneros, is looking at what processes create VEGF-A in the eye, to …
RetroSense Therapeutics to Present at the 8th Ocular Diseases Drug Discovery Conference
RetroSense Therapeutics is a privately-held biotechnology company developing life-enhancing gene therapies designed to restore vision in patients suffering from blindness due to retinitis pigmentosa (RP) and advanced dry age-related macular degeneration (advanced dry-AMD). RetroSense is developing optogenetic approaches to partial vision restoration in retinitis pigmentosa and potentially dry …
SBIR-STTR Success: Charlesson LLC/EYECRO
Macular Degeneration is the leading cause of blindness and vision loss in people over 50 –and with life expectancies well into the 80s, it is estimated that 1 and 3 elderly individuals will have to deal with this degenerative disease. The remedy? Monthly injections (via needle) into the back of the eye, where the disease lives. Not only does this method come with the possibility of an infection, …
Transplanted Rod Precursor Cells Restore Vision in Experimental Mice
Studies in mouse models of night blindness have demonstrated that vision can be restored by transplanting rod precursor cells taken from mouse neonates directly into the retina of recipient animals. The University College London (UCL) Institute of Ophthalmology-led team showed that the transplanted rod cells made synaptic connections with the existing retinal circuitry, were light responsive, and …
Flexible Adult Stem Cells, Right There in Your Eye
Researchers reporting in the January issue of Cell Stem Cell, a Cell Press publication, have identified adult stem cells of the central nervous system in a single layer of cells at the back of the eye. That cell layer, known as the retinal pigment epithelium (RPE), underlies and supports photoreceptors in the light-sensitive retina. Without it, photoreceptors and vision are lost. "You can get …
