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.

Ten years of data suggest that AREDS2 supplements are associated with a reduced risk of macular degeneration progression without any increase in lung cancer risk, according to a follow-up study published online June 2, 2022, by JAMA Ophthalmology.

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.

A recent analysis found a link between vision loss and higher risk of dementia. The results suggest improving visual acuity, such as with eyeglasses or cataract removal, might help maintain cognitive fitness in older adults.

There are many choices for lenses to replace a cataract. Examples include lenses that allow a person to see clearly at a single distance, or at several distances. Some types can correct astigmatism. When deciding which lens to choose for cataract surgery, people should consider costs, daily vision needs, existing vision problems, and pros and cons; for example, some lenses have more vision range than others, but also have risks of glare at night; some lenses still require a person to use glasses for up-close or distance vision.

Most people have eye twitches at some point in their lives. These are usually a sign of minor physical or mental stress. Spasms can be calmed with a warm compress, sleep, or exercise. People should see a doctor if one or both eyes close involuntarily with spasms.

While not as routine as cataract surgery, corneal transplants are becoming more common. A number of things can go wrong with the cornea, especially as people get older, and a partial-thickness or full-thickness transplant can restore vision.

Vigorous exercise may improve dry, itchy eyes by boosting tear production and quality.

A 2021 study found that people who underwent cataract surgery (a procedure replace the lens of the eye) appeared to have a lower risk of developing dementia than those who had cataracts but did not undergo surgery.

An observational study published online Dec. 6, 2021, by JAMA Internal Medicine found that the risk of developing dementia was 29% lower in people who underwent cataract removal, compared with people who didn't have cataracts removed.
