FDA Clears Gene Therapy Trial for GA
The FDA has approved the initiation of the Opti-GAIN phase 1/2 clinical trial for CTx001, an adeno-associated virus (AAV)-based gene therapy targeting geographic atrophy (GA) secondary to age-related macular degeneration (AMD). Developed by Complement Therapeutics, CTx001 delivers a truncated version of complement receptor 1 (mini-CR1) to modulate both the classical and alternative complement pathways. The trial aims to evaluate the safety, tolerability, and preliminary efficacy of this novel therapy.
Navigating MacTel From Diagnosis to Therapy
Macular telangiectasia type 2 (MacTel) is a chronic, progressive, bilateral macular dystrophy that primarily affects individuals in midlife. Characterized by insidious central vision loss and retinal degeneration, it often goes undiagnosed until advanced stages. Recent advancements, such as the approval of revakinagene taroretcel (Encelto), offer new hope for treatment. Early detection and informed patient counseling are crucial to optimizing therapeutic outcomes.
Navigating Optogenetics in the IRD Pipeline
Optogenetics is emerging as a promising gene therapy for advanced inherited retinal diseases (IRDs) like retinitis pigmentosa, Stargardt disease, and Leber congenital amaurosis. By introducing light-sensitive opsins into surviving retinal cells, this approach aims to restore visual function even in the absence of functional rods and cones. Notably, optogenetic therapies are mutation-agnostic, offering potential benefits across various IRD subtypes. The field is advancing rapidly, with several clinical trials underway to assess the efficacy and safety of optogenetic interventions in patients with late-stage retinal degeneration.
AI Without Borders
The Global RETFound initiative is a groundbreaking international collaboration aimed at addressing health inequities in ophthalmology. Spearheaded by researchers from institutions such as Moorfields Eye Hospital and University College London, the project seeks to create the world’s first globally representative retinal AI model. By training on over 100 million eye images from 65 countries, RETFound aims to enhance AI's diagnostic capabilities across diverse populations, ensuring equitable access to advanced eye care worldwide.
Study maps intricate muscle patterns behind blinking and eyelid movement
A blink of an eye seems natural and instantaneous, but is it? Without a functioning eyelid, the eye can become dry, irritated and eventually lose the ability to see clearly. Now, a team of UCLA biomechanical engineers and ophthalmologists has uncovered new details about the muscle that controls blinking, offering a pathway toward developing blink-assisting prostheses.
New study compares the effects of low-level red light with 0.01% atropine treatment on axial length and choroid in myopic children
An investigative team led by first author Xuena Pang, MD, reported their experience with the use of red light in children with myopia. They reported that 6 months of treatment showed that repeated low-level red light (RLRL) application was more effective than 0.01% atropine for controlling axial elongation and myopic progression in myopic children.
What is hyperemic conjunctivitis?
Hyperemic conjunctivitis (HC) or “conjunctival hyperemia” refers to redness of the conjunctiva, the thin, transparent membrane that covers the white of the eye. Other names for HC include “red eye” or “pink eye”.
Amblyopia (lazy eye) treatment: Eye patching, drops, digital therapies and more
Amblyopia, also known as "lazy eye," is a common eye condition in kids that develops when a child has an eye that does not see well. This is caused by a poor connection between the eye to the brain, which can happen for a variety of different reasons. Amblyopia is more common in one eye but can also happen in both eyes.
Eye tracking metrics may help identify concussion-related vision disorders
In a new study led by Children's Hospital of Philadelphia (CHOP), researchers found that novel eye-tracking metrics can help properly identify concussion-related vision disorders, a common phenomenon among patients with persisting post-concussive symptoms that last more than 28 days after their initial injury. The findings, recently published in the Journal of Sport and Health Science, suggest that objective infrared eye tracking could help identify which patients would benefit the most from referrals to and treatment from concussion specialists.
Amino acid glutamine is important for eye health, research finds
Photoreceptor death is the cause of vision loss in many retinal diseases, and there are no effective therapies that improve their survival. In a paper published in eLife, University of Michigan researchers studied the dependence of photoreceptors on glutamine. Their results indicate that maintaining the balance of amino acids in these cells is important for photoreceptor health.
