Could Viagra and Cialis Help Protect Eye Health? New Study Suggests a Link
A new observational study of more than 47,000 men aged 40 and older found that users of phosphodiesterase‑5 (PDE‑5) inhibitors such as Viagra, Cialis and Levitra had a modestly lower incidence of glaucoma signs and open‑angle glaucoma over three years. After one year, 6.5% of users were at risk versus 9.7% of non‑users, and 2.1% developed open‑angle glaucoma compared with 3.2% of non‑users. The researchers attribute the effect to improved ocular blood flow, but note the analysis is based on medical records, not a randomized trial.
