Experts Urge Regular Screenings to Prevent Glaucoma-Related Blindness

Glaucoma-related blindness is a major public health concern in Spain, largely because the disease shows no symptoms in its early stages. To mark World Glaucoma Day, the Quirónsalud Costa Adeje Hospital highlighted that early detection is the only way to prevent permanent vision loss. Experts stress that most cases of blindness from glaucoma can be avoided with regular eye exams.

The risk factors for glaucoma are varied. While age is a key factor—with risks rising after 40 and increasing significantly after 60—genetics also play a major role. People with a family history of the disease, as well as those of Asian or African descent, are at higher risk. Other factors, such as severe nearsightedness or farsightedness and conditions like diabetes, can also increase the likelihood of developing the disease.

Dr. Patricio Adúriz, an ophthalmologist at the hospital, notes that patients often do not realize they have glaucoma until they have already experienced significant vision loss. Because of this, a simple, non-invasive test called tonometry—which measures eye pressure—is essential for screening. If the results are abnormal, doctors may follow up with more advanced tests, such as optical coherence tomography (OCT) or a detailed examination of the eye’s structure.

Early diagnosis is vital because it allows doctors to manage eye pressure, which is the most effective way to treat the condition. By stabilizing eye pressure, patients can slow or stop the progression of the disease and protect their vision.

Given that glaucoma affects roughly 6% of the population, regular screening is the best defense. Experts recommend that everyone over the age of 40 have a comprehensive eye exam every one to two years, or sooner if they have additional risk factors.
