Transplanted neural progenitor cells survive one year in patients with retinitis pigmentosa

New, previously unpublished clinical data was presented today at ISSCR 2026 demonstrating that transplanted human neural progenitor cells survived for at least one year following subretinal transplantation in patients with retinitis pigmentosa (RP), while maintaining a favorable safety profile.

New eye imaging technology captures clearer details of retina

Modern OCT devices can look inside the eye without a scalpel - but they do not always capture everything that matters. Some critical information is simply lost, blurred by scattered photons.

AI imaging technique detects early endometrial cancer with high accuracy

Endometrial cancer is the most common gynecologic cancer, with more than 69,000 cases diagnosed in the U.S. in 2025 and increasing up to 3% annually.

AI and polarized light improve early detection of keratoconus

Keratoconus is a progressive eye disease that weakens and thins the cornea, the clear front surface of the eye. In its early, subclinical stage, the cornea can still appear normal on routine exams.

Uncovering the hidden retinal risks of modern dentistry

Dentists are exposed to intense lighting for long hours, but its long-term impact on eye health is often overlooked. This study evaluates whether chronic exposure to dental lighting, especially blue and white LEDs, can damage the retina and disrupt its normal function. By combining human data with advanced imaging and animal models, the research uncovers hidden occupational risks and highlights the need for safer lighting practices to help protect dentists' vision.

Dual imaging reveals hidden causes of heart attacks without blockages

When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack. She was 36, a new mom, and otherwise healthy.

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics.
