New thinking on glaucoma treatment

Published October 1, 2022

Some people with newly diagnosed mild to moderate open-angle glaucoma have another option for first-line treatment. Instead of using prescription eye drops initially, they can have a laser procedure called selective laser trabeculoplasty (SLT). SLT uses light pulses to help clean up debris clogging the eye’s natural drains. Clogged drains lead to elevated eye pressure that damages the optic nerve. SLT's effects wane after three to five years, at which point it may be necessary to have the procedure again, or to begin using eye drops to treat glaucoma.

Around menopause, a decline in estrogen can trigger low-grade inflammation that leads to unexpected symptoms from head to toe. Symptoms can affect the digestive tract, skin, joints, eyes, ears, and heart, among other areas. A 2022 study found that estrogen loss can even fuel the jaw pain known as temporomandibular disorder. A year or longer can pass before many women connect symptoms with menopause. Women can take lifestyle measures to lower inflammation, such as eating more fruits and vegetables, avoiding processed foods, and exercising.
