A new gene therapy has restored vision in patients with Leber congenital amaurosis type I (LCA1), a rare genetic condition causing blindness. In a small trial, those receiving the highest dose saw up to a 10,000-fold improvement in light sensitivity and significant gains in reading and navigation abilities.

New research reveals that individuals who experience vision loss before age 10 struggle more with judging sound distance compared to those who lose sight later in life. This difficulty in perceiving the location of sounds has significant implications for safety and navigation. The study highlights the need for tailored healthcare solutions for those with early vision loss to enhance their quality of life.

Researchers found that daily antioxidant supplements slow the progression of late-stage dry age-related macular degeneration (AMD). The supplements help preserve central vision by slowing the expansion of geographic atrophy regions in the retina. This finding supports the use of AREDS2 supplements for people with late dry AMD.
