Hormonal contraception not associated with prevalence of idiopathic intracranial hypertension

Hormonal contraception, including birth control pills and intrauterine devices (IUDs), is not associated with an increased prevalence of a brain pressure disorder called idiopathic intracranial hypertension, according to a meta-analysis published on March 25, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Dual sensory loss affects confidence in navigation and sound localization

According to a recent multi-institute PLOS One study led by the Multisensory Research Lab at the Wilmer Eye Institute, Johns Hopkins Medicine, time of hearing loss onset is a key determinant of patient confidence and self-reported sound localization abilities - the ability to perceive and locate objects in an environment - even in individuals who use hearing aids or who have received vision rehabilitation training.

Wegovy linked to higher risk of eye stroke and vision loss

Wegovy, a GLP-1 agonist for weight loss, may carry the highest risk of 'eye stroke' (ischemic optic neuropathy) and sudden sight loss of the semaglutide drugs, finds an analysis of unintended side effect reports published in the British Journal of Ophthalmology.

Vitamin A and thyroid hormones in the retina shape fetal vision

Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found.

Weight loss drug tirzepatide may lower the risk of diabetic retinopathy

The popular diabetes and weight loss medication tirzepatide (brand name Mounjaro or Zepbound) may lower the risk of diabetic retinopathy, a leading cause of vision loss, according to Weill Cornell Medicine investigators.

Addiction consults improve care for drug-related eye infections

Eric Gaier, MD, PhD, and Dean Eliott, MD, of the Department of Ophthalmology at Mass Eye and Ear, a member of the Mass General Brigham healthcare system, are co-authors of a paper published in Ophthalmology Retina, "Substance Use Disorder Interventions and Ophthalmic Outcomes for Injection Drug Use-Associated Endogenous Endophthalmitis."

Metformin linked to lower odds of intermediate macular degeneration in people with diabetes

A five-year image-based study in people with type 2 diabetes found metformin use was associated with lower odds of developing intermediate age-related macular degeneration. The observational findings suggest a potential protective link but do not establish causation and warrant prospective clinical trials.

MRI measures of glymphatic activity may improve noninvasive intracranial hypertension diagnosis

A new study led by investigators from Mass General Brigham shows that a brain waste- "clean-up" system is influenced by intracranial pressure.

Scientists offer new insight into how common parasite T. gondii causes disease

A University of California, Riverside team of scientists has found that Toxoplasma gondii, a common parasite affecting up to one-third of the global population, is far more complex than previously believed.

Ultra-thin nanotechnology enables safe wireless stimulation for retinal degeneration

An international research team led by Prof. Dr. Sedat Nizamoğlu from the Department of Electrical and Electronics Engineering at Koç University has developed a next-generation, safe, and wireless stimulation technology for retinal degenerative diseases that cause vision loss.

Non-coding RNA mutations unveiled as new cause of retinitis pigmentosa

Retinitis pigmentosa (RP) is a genetic eye disorder affecting around one in 5,000 people worldwide. It typically begins with night blindness in youth and progresses to tunnel vision as daylight-sensing photoreceptor cells in the retina gradually die, potentially leading to blindness over time.
