by Kim Krieger, University of Connecticut The image show two optic nerves, six weeks after they have been crushed (injury marked with a rhombus.) The nerves project fibers from left to right. Live nerve tissue glows green in this image, while damaged nerve tissue is dark. The top nerve was not treated with any regenerative factors,...

Blindness from some inherited eye diseases may be caused by gut bacteria, news study suggests
by University College London Credit: CC0 Public DomainSight loss in certain inherited eye diseases may be caused by gut bacteria, and is potentially treatable by antimicrobials, finds a new study in mice co-led by a UCL and Moorfields researcher. The international study observed that in eyes with sight loss caused by a particular genetic mutation, known...

Nanotechnology may improve gene therapy for blindness
by Oregon Health & Science University Oregon Health & Science University and Oregon State University researchers are developing a new approach to deliver gene therapy to address blindness-causing genetic mutations. Their new method encases gene-editing molecules inside a shell of lipid nanoparticles. This scientific illustration shows the approach’s lipid nanoparticle shells, which appear as fuzzy beige balls after...

Progress toward a stem cell–based therapy for blindness
by Katherine Unger Baillie, University of Pennsylvania Following a transplantation procedure, human photoreceptor precursor cells labeled red migrated and integrated into a degenerated canine retina. The green label is a synaptic maker, suggesting the transplanted cells began forming a connection with second-order neurons in the retina.

A step closer to treatment for the most common form of blindness
by University of Manchester Picture of the back of the eye showing intermediate age-related macular degeneration. Credit: National Eye Institute Scientists at The University of Manchester have taken an important step towards finding a treatment for age-related macular degeneration (AMD), the most common form of adult blindness in the developed world. The researchers were able...

Scientists pinpoint genetic target with promise for treating many forms of blindness
by Trinity College Dublin Figure 1. Spatial vision following rotenone insult. Rotenone was delivered bilaterally via intravitreal injection. Optokinetic responses were measured 2 months and 4 months post-injection using an OptoMotry virtual optokinetic system (Cerebral Mechanics). Bar charts represent the mean combined spatial frequency threshold. Error bars represent SD, ** p < 0.01, **** p...
