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…
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…
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 age-related macular degeneration. Read the entire article…
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…
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…
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…
