This week: Glaucoma, genetic resilience and poison center activities

Glaucoma is the leading cause of irreversible blindness worldwide. It can hit at any age but is more common in people older than 60.

In this week's "HealthLink on Air," Upstate ophthalmologist Preethi Ganapathy explains that glaucoma involves damage to the optic nerve and increased pressure within the eye. The condition tends to affect one's vision at the edges first. A complete eye exam, with eye drops, is needed on a regular basis to detect glaucoma early, when its progress can best be slowed, she says since there is no cure.

Treatment to lower the pressure can include drops and/or laser surgery.

Ganapathy, an assistant professor of opthalmology and visual sciences, conducts glaucoma research as well as treating patients.

In addition, this week's program includes public education coordinator Lee Livermore discussing the types of call the Upstate New York Poison Center handled in 2019, and neuroscientist Stephen Glatt telling how genetic resilience provides protection against some diseases. Tune in this Sunday, February 23 at 6 a.m. and 9 p.m. for "HealthLink on Air."
