This was posted in the sci.med.vision newsgroup.  It should be of interest to this group. EYEWORLD WEEK MARCH 10, 1997, Vol. 2, No. 10 High-dose asthma inhalants found to increase glaucoma risk MONTREAL — McGill University researchers have linked the use of steroid-containing asthma inhalants to an increased risk of glaucoma in people using high doses for several months at a time, according to a report in the Journal of the American Medical Association. People using high doses — defined as two puffs from a typical inhaler four times daily — for three months or more had a 44% higher risk of glaucoma or ocular hypertension than those who did not use steroid-containing inhalants. The researchers warned people not to stop using the inhalers, but to have regular checks for glaucoma. Critics of the study noted that the researchers used insurance records rather than actual medical charts. Glaxo Wellcome, a major supplier of inhaled steroids, downplayed the findings, noting that steroid inhalation has long been associated with a slight increased risk of glaucoma. ________________ Alcon enters pact to discuss pneumatic trabeculoplasty PHOENIX, Ariz. — Ophthalmic International Inc., a subsidiary of Coronado Industries Inc., and Alcon will discuss Ophthalmic’s pneumatic trabeculoplasty device under a confidentiality agreement, Coronado announced last week. Ophthalmic holds a method patent for pneumatic trabeculoplasty, as well as a patent on a device for performing the procedure. The device consists of a vacuum ring applied outside the eye over the trabecular meshwork. The procedure appears to work by restoring outflow through the meshwork. Though the effect usually fades, the procedure reportedly can be safely repeated. ________________ Copyright 1997 ASCRS Ophthalmic Services Corp. All rights reserved.
