Groundbreaking Central Retina Transplant Restores Sight in Woman

Turin surgeons performed the world’s first simultaneous transplant of the central retina (macula) along with cornea and sclera from Elena’s left eye to her right eye, enabling the 67-year-old to immediately recognize her son and her dog after years of blindness. The six-hour procedure, led by Professor Michele Reibaldi at Molinette Hospital, used the undamaged optic nerve in the right eye while salvaging tissues from the left eye, signaling a new frontier in ocular surgery with early signs of success.

Large study links tadalafil use to higher glaucoma risk

An observational study of about 74,000 men aged 40+ over up to five years found tadalafil (Cialis) use for erectile dysfunction and enlarged-prostate symptoms was associated with a 22% higher risk of glaucoma, a 32% higher risk of elevated intraocular pressure, and a 33% higher risk of primary open-angle glaucoma versus nonusers. The study, published in the British Journal of Ophthalmology, cannot prove causation; researchers urge regular baseline eye exams for long‑term users, especially those with glaucoma risk factors.

Tiny Eye-Scan Tech Aims to Shield Astronauts’ Vision on Deep-Space Missions

The European Space Agency is funding Siloton to build a compact, self-administered retinal scanner powered by quantum photonics to monitor spaceflight-associated neuro-ocular syndrome (SANS) on long missions, enabling more frequent eye checks without ground support; while power, mounting, and head-stabilization present challenges, the tech could improve astronauts’ ocular health data and spill over to terrestrial eye care.

Eye Safety Alert: Percussive Massage Guns Can Cause Retinal Tears

A BMJ Case Reports study documents a young man who developed multiple retinal tears and retinal detachment after using a percussion massage gun on and around his eyes for months. Laser treatment repaired the damage, highlighting the eye injury risks and the lack of clear safety guidelines for ocular use of these devices.

Ollin Biosciences bags $330M to push eye-disease therapy into Phase 3

Ollin Biosciences raised $330 million in a Series B to push its eye-disease therapy into Phase 3 trials for diabetic macular edema and wet age-related macular degeneration, with lead investors including TCGX and ARCH Venture Partners and participation from a pension fund and crossover investors, in one of biotech’s largest Series B rounds in years.

First Patient Dosed in Eye-Targeted Cellular Reprogramming Anti-Aging Trial

Life Biosciences dosed the first patient in a human trial of ER-100, a cellular reprogramming therapy designed to make aging cells act younger; the injection targeted the eye for glaucoma and uses three of the Yamanaka factors with a doxycycline switch to control activity. If safe and effective, it could open the door to systemic anti-aging therapies, but cancer risk remains a concern. The study will monitor safety over six months with up to about 20 participants enrolled across multiple cities.

Two Injured in San Jose Kaiser Office Shooting, Authorities Investigating

Two people were shot at Kaiser medical offices in San Jose (5755 Cottle Rd), suffering life-threatening injuries and transported to local hospitals. Police say the incident appears isolated and they are investigating with a large police presence in the area; the ophthalmology facility involved is separate from the Kaiser hospital and has no emergency services.

Electric reshaping of the cornea could replace lasers for vision correction

Researchers are testing electromechanical reshaping (EMR) to temporarily soften and reshape the cornea with a mild electric current, potentially offering a cheaper, less invasive alternative to LASIK; early rabbit-eye experiments show improved focusing power with preserved cell viability, and the approach could address myopia and other refractive errors, but it is still experimental and must undergo extensive animal and clinical testing.

Pocket-friendly gel revives vision in seven of eight eyes with chronic low pressure

Repeated injections of a cheap clear surgical gel (hydroxypropyl methylcellulose) re-inflated eyes collapsed by chronically low pressure and restored usable vision in seven of eight patients at Moorfields Eye Hospital. The gel’s transparency lets clinicians monitor the retina, offering a potential, less risky alternative to silicone oil. Side effects included inflammation and transient vision loss in some cases but were reversible; larger trials are needed to confirm safety and how long the benefits last.

Eye symptoms flag tougher long COVID, Yale study finds

A Yale-led study of 595 adults with long COVID found that new eye symptoms after infection (blurred vision, dry eyes, floaters) are linked to a more severe disease profile, including worse overall health, higher autonomic symptoms (POTS, dizziness, tremors), more GI issues and migraines, and greater financial/housing instability; authors say ocular symptoms may indicate more-severe long COVID and call for more research, though limitations include self-reported data and a predominantly female/White sample.

Axpaxli edges Eylea on vision retention with fewer injections, but durability gap narrows

Ocular Therapeutix reported that Axpaxli met a key endpoint in a Phase 3 wet AMD trial by maintaining patients’ vision with fewer injections than the standard treatment. At 9 and 12 months after a single injection, 74% and 66% of Axpaxli patients maintained vision versus 56% and 44% for low-dose Eylea. While the primary goal was achieved, the durability advantage over Eylea was smaller than investors expected, which could influence the drug’s commercial potential as the company pursues FDA approval.

Sleepless nights left her eyelids flipping inside out, CPAP fixed them

A 39-year-old Brooklyn woman with six weeks of eye irritation developed floppy eyelids that rolled inside-out, a condition linked to obstructive sleep apnea and obesity. A sleep study showed moderate OSA (27 events per hour). After CPAP treatment, along with eye lubrication/patches and weight loss, her eyelids stopped flipping within two weeks and her sleep improved. The syndrome is often managed non-surgically, though some cases may require surgery.

Link Found Between Sleep Apnea and Eye Disease Risk

A study by the Centre for Eye Research Australia has found that moderate-to-severe obstructive sleep apnea (OSA), which causes low oxygen levels at night, is linked to an increased risk of developing wet age-related macular degeneration (AMD). The research suggests that nocturnal hypoxia may damage the retina, which requires high oxygen levels at night, potentially making OSA a modifiable risk factor for wet AMD. The study involved 225 participants and indicates that treating OSA could reduce the risk of AMD progression.

Unseen Eye Symptoms: Early Indicators of Diabetes Risk

An overlooked symptom of diabetes, diabetic retinopathy, can lead to blindness if untreated, warns ophthalmologist Cindy Cai. This condition, caused by high blood sugar damaging the retina's blood vessels, highlights the importance of regular eye exams and lifestyle changes to manage blood sugar, blood pressure, and cholesterol. Early detection and treatment are crucial to prevent vision loss, especially for those with long-term diabetes, high blood pressure, or high cholesterol.
