by Dennis Thompson Age-related macular degeneration can lead to vision loss in seniors, but new therapies have offered fresh hope for preserving eyesight later in life, eye experts say. These cutting-edge therapies benefit both the dry and wet types of age-related macular degeneration (AMD), says the American Society of Retina Specialists (ASRS). Eleven million people...
by Ernie Mundell As levels of nighttime artificial outdoor light rise, so do the odds for a leading cause of vision loss, age-related macular degeneration (AMD). South Korean researchers found that people living in areas of that country with the highest levels of streetlights and other artificial light had more than double the odds for...
Age-related macular degeneration is the leading cause of vision loss in Western countries. The condition, a deterioration of central vision, begins when droplets of lipids and proteins called lipofuscin accumulate in the retina and damage cells. Effective treatments for age-related macular degeneration (AMD) are not available and it remains unclear how healthy eyes prevent this...
by National Eye Institute The complement membrane attack complex is a pore that inserts into the cell membrane. The complex is formed by up to 18 C9 subunits (purple), the C5, C6, and C7 subunits (various shades of green), and the C8-alpha, C8-beta, and C8-gamma subunits (shades of red). Side (left) and Top (center) views show...

A structural model of a complex comprised of one neutralizing anti-brolucizumab antibody in blue, and two non-neutralizing antibodies in light yellow. Brolucizumab is shown in gray, with the VEGF-A-binding CDRs highlighted in magenta. ADA, anti-drug antibody; CDR, complementarity-determining region; VEGF-A, vascular...

BOSTON UNIVERSITY SCHOOL OF MEDICINE (Boston)— Recent evidence has emerged to suggest that age-related macular degeneration (AMD) is a clinical risk factor for increased risk for infection and mortality. AMD has been reported to confer higher risk of severe complications of SARS-CoV-2 infection, including respiratory failure and death (25 percent), a risk which is higher than Type 2...

Twenty-eight-hour post-transduction cells were insulted with 5-mM NaIO3 (F–O) and 24-h post-insult cells were fixed and stained with Phalloidin-iFluor 647 (F-actin, light blue), and CPN60 (mitochondrial marker, magenta) and 8-OHdG-Alexa Fluor 488 (oxidative stress marker, green) immunocytochemistries;...
