Sleep Apnea Can Raise Risk for Retinal Vein Disease
Obstructive sleep apnea (OSA) was associated with a notably higher risk of developing retinal vein occlusion across different demographic groups, with the greatest increase observed in people of Hispanic or Latino heritage. Among patients with preexisting retinal vein occlusion, the sleep disorder was associated with further ocular complications.
METHODOLOGY:
Researchers reviewed electronic health records of adults receiving ophthalmologic care and grouped them by the absence (n = 3,279,582; mean age, 50.2 years; 56.9% women) or presence (n = 19,918; mean age, 68.3 years, 53.0% women) of retinal vein occlusion at baseline; the first group also was stratified on the basis of sex, age, and ethnicity.
Within each cohort, patients with OSA were compared with those without the condition to estimate the risk for incident retinal vein occlusion (first group) and the risk for complications or the need for invasive treatment (second group).
Complications of retinal vein occlusion included swelling of the macula, abnormal growth of new blood vessels in the retina, or bleeding in the vitreous region; invasive treatments included pars plana vitrectomy, intravitreal injections of anti-VEGF, or laser therapy of the retina.
TAKEAWAY:
OSA was linked to a 28% increased risk for incident retinal vein occlusion in women (risk ratio [RR], 1.28; 95% CI, 1.14-1.45) and a 35% increased risk for the condition in men (RR, 1.35; 95% CI, 1.19-1.52).
The association between OSA and retinal vein occlusion was the most prominent in the Hispanic/Latino population, followed by the non-Hispanic White and Black populations; however, the association was not observed in Asian patients.
Among patients with retinal vein occlusion at baseline, those with OSA faced higher risks for swelling of the macula (RR, 3.70; 95% CI, 3.17-4.31), bleeding in the vitreous region (RR, 2.29; 95% CI, 1.64-3.20), and abnormal growth of new blood vessels in the retina (RR, 2.22; 95% CI, 1.69-2.91); they also received more intravitreal injections of anti-VEGF agents and underwent laser therapy of the retina.
IN PRACTICE:
'Clinicians should consider regular ophthalmology screening of all patients with OSA and, conversely, incorporating OSA screening into regular follow-up appointments for patients with' retinal vein occlusion, the researchers reported. Whether early initiation of continuous positive airway pressure can mitigate the risk for retinal problems in patients with OSA 'would be a valuable area for further research,' they added.
SOURCE:
This study was led by Hejin Jeong, Case Western Reserve University School of Medicine, Cleveland. It was published online on July 16, 2025, in Eye.
LIMITATIONS:
Although polysomnography was used to diagnose OSA, data on the number of apnea-hypopnea events and drops in blood oxygen were not available. Since OSA can be significantly underdiagnosed, misclassification bias may have occurred.
DISCLOSURES:
This study received support from the Clinical and Translational Science Collaborative of Cleveland, Research to Prevent Blindness Challenge Grant, and Cleveland Eye Bank Foundation Grant. Some authors disclosed receiving personal fees, research grants, and having other ties with many pharmaceutical companies.

Weiss Memorial Hospital's access to Medicare payments revoked, IDPH announced
The future of Weiss Memorial Hospital in Uptown is uncertain after the federal Department of Health and Human Services announced that it is revoking the facility's ability to receive Medicare payments. Starting on Aug. 9, Medicare won't pay Weiss for inpatient services. The move could be devastating for the safety-net hospital, which the Sun-Times reported received over half of its 2023 revenue from the program. While the notice didn't elaborate on why it deemed Weiss not "compliant" with its guidelines, the hospital's air-conditioning system failed last month, forcing dozens of patients to be transferred to its sister institution, West Suburban Hospital in Oak Park. Since then, Weiss has rendered only limited services to patients while it awaits spare parts to fix the air conditioning. In a statement, a spokesperson for the Illinois Department of Public Health said: "The Illinois Department of Public Health has been closely monitoring the situation at Weiss Memorial Hospital. As required by law, the results of our surveys of the hospital are shared with the federal Center for Medicare and Medicaid Services (CMS). CMS holds the authority to and made the decision to terminate Weiss's involvement with the Medicare program effective August 9, 2025. There is a process for reconsideration that Weiss can pursue. IDPH is committed to ensuring patient safety and quality of care at healthcare facilities in Illinois and will engage with Weiss as appropriate."

Wearable hydration monitor could help prevent heatstroke, scientists say
A new wearable sensor could help people avoid the dangers of dehydration by alerting them when their bodies need more water. Developed by researchers at the University of Texas, the non-invasive device continuously measures hydration levels in real time and wirelessly transmits the data to a smartphone, according to an SWNS report. "Dehydration is a silent threat that affects millions of people every day," said Professor Nanshu Lu of the University of Texas at Austin, who led the study. "Our wearable sensor provides a simple, effective way to monitor hydration levels in real time, empowering individuals to take proactive steps to stay healthy and perform at their best," she added, per SWNS. The sensor uses a method called bioimpedance, which sends a small, safe electrical current through the body via strategically placed electrodes. The current's flow depends on how hydrated the tissues are — hydrated tissue allows the current to pass easily, while dehydrated tissue resists the flow, according to SWNS. "Arm bioimpedance is not only sensitive to hydration changes, but also aligns closely with whole-body hydration measurements," said study co-author Dr. Matija Jankovic, a post-doctoral researcher in Professor Lu's lab. "Dehydration is a silent threat that affects millions of people every day." "This means the sensor can be a reliable surrogate for tracking hydration levels, even during everyday activities like walking, working or exercising," Jankovic added. To validate the device, the research team conducted multiple experiments, including a diuretic-induced dehydration study and a 24-hour real-life trial. Participants were given medication to promote fluid loss. Their hydration levels were monitored via the wearable and compared to urine samples. The device showed a strong correlation between changes in arm bioimpedance and total body water loss, SWNS reported. The findings were published in the Proceedings of the National Academy of Sciences. The new sensor could offer an accessible and wearable alternative to traditional hydration tracking methods, such as urine or blood analysis, which are invasive, time-consuming and impractical, the researchers noted. Hydration is known to be essential for regulating body temperature, maintaining organ function and supporting many other vital processes. Even mild dehydration can impair concentration and performance, while severe dehydration may lead to serious health problems like heatstroke, kidney stones and cardiovascular issues, according to experts. Beyond everyday use, the researchers believe the technology could benefit patients with chronic dehydration, kidney disease or heart conditions. Athletes, too, could use the wearable to stay safe and perform optimally, especially in hot weather. While the current model tracks relative hydration changes, Professor Lu said the team aims to develop reference data for absolute hydration levels. They are also exploring more advanced wearable formats, like breathable electronic tattoos or sweat-absorbing patches, to enhance comfort during long-term use.

Air quality alert in New York City area due to smoke from Canada wildfires
An air quality alert was issued by the New York State Department of Health on Saturday due to smoke from wildfires in Canada. The air quality health advisory covers New York City and the surrounding metropolitan area, including Long Island, as well as the Lower Hudson Valley, Upper Hudson Valley and the Adirondacks. The advisory went into effect at noon and expires at midnight. Today is another hot day in the Tri-State Area and more storms could hit the region Sunday. New York says the air quality forecast is "unhealthy for sensitive groups" Saturday. According to the National Weather Service, the air quality index (AQI) is predicted to be greater than 100, and could even reach up to 135 in NYC, which indicates a greater health concern due to fine particles in the air. Put plainly, the AQI helps measure the severity of air pollution and categorizes the health risks. The higher the number, the greater the risk. "People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, and those with preexisting respiratory problems such as asthma or heart disease. Those with symptoms should consider consulting their personal physician," the NWS alert says. New York health officials recommend limiting strenuous outdoor activities to reduce the risk of adverse health effects when there are elevated levels of pollution, according to the NWS.
