Study Links Colder Temperatures to Higher IOP in Patients with Glaucoma
A retrospective study published in the British Journal of Ophthalmology found that lower ambient temperatures were significantly associated with higher intraocular pressure (IOP) in patients with medically controlled primary open-angle glaucoma (POAG), suggesting that environmental temperature may contribute to IOP fluctuations.1 The study, led by Toru Ikushima, MD, of Kyoto Prefectural University of Medicine in Japan, analyzed 2,655 IOP measurements from 154 eyes of 77 patients treated between 2012 and 2023. Participants had a mean age of 65.8 years and were followed for an average of 5.2 years.
