They call it “the thief of sight” because it advances silently, without causing pain or obvious signs until it produces irreversible damage. Glaucoma is an eye disease that progressively deteriorates the optic nerve and today affects more than 80 million people in the world, according to the World Health Organization. Among those who live or lived with this pathology are figures such as Bono, Whoopi Goldberg and Ray Charles, three artists who, from different moments in their lives, helped make visible the importance of early diagnosis.
Bono more than once said that his ever-present dark glasses are due to the ocular sensitivity caused by the disease; Goldberg revealed that his severe headaches are linked to glaucoma; while the iconic musician Ray Charles progressively lost his sight during his childhood due to which doctors did not diagnose him with juvenile glaucoma.
The musician said that his mother, Retha, could not stand condescension. “When I started to feel sorry for myself, she would stand up and tell me, ‘You’re blind, not stupid. You’ve lost your sight, not your mind,’ and she’d make me see that I could do anything anyone else could do.”
Glaucoma is an eye disease that progressively damages the optic nerve.
Although famous cases are often mentioned, glaucoma affects people of all ages, even those with no family history. Its most worrying characteristic is that it progresses without clear symptoms for a long time. According to the Pan American Health Organization, it is the second cause of irreversible blindness in the world, only surpassed by cataracts—which can be reversed with surgery. Glaucomatous damage, on the other hand, does not recover: that is why early detection is decisive.
Bono often says that his black glasses are not a rockstar hallmark but a tool to live with his condition; Goldberg insists that his pain taught him not to underestimate signs; and the story of Ray Charles reminds that late diagnosis can change everything
To take into account
One of the first warning signs is the gradual loss of the visual field, especially laterally. Many people discover the disease when they already see as if “through a tunnel”, even though they have previously spent years without noticing changes. In some types of glaucoma, colored halos around lights, blurred vision, eye redness or intense pain may appear, but these symptoms are less common. In most cases, progress is silent.
Glaucoma is generally caused by an increase in intraocular pressure, which damages the optic nerve. However, not all patients with high pressure develop glaucoma nor do all glaucomatous patients have high pressure; That is why specialists insist that the diagnosis should not be based on a single measurement, but on complete controls. The Argentine Society of Ophthalmology recommends performing an annual examination after age 40, and sooner if there is a family history, diabetes, high myopia, prolonged use of corticosteroids or hypertension.
Controls
Prevention is directly linked to these periodic controls. A complete checkup includes eye pressure measurement, evaluation of the optic nerve, study of the visual field and, in some cases, imaging tests that allow a detailed analysis of the structure of the eye. Detecting glaucoma in early stages allows us to slow its progression and preserve the remaining vision.
Although there is no definitive cure, there are effective treatments to control eye pressure and prevent damage from progressing. The most common are hypotensive drops, which must be applied every day according to medical indication. In other cases, laser or minimally invasive surgeries are used to help improve the drainage of the aqueous humor. Specialists emphasize that suspending or spacing treatment on your own is one of the most frequent and dangerous errors.
Where to turn
In Argentina there are reference centers for glaucoma care, such as the Pedro Lagleyze Ophthalmology Hospital, the Santa Lucía Hospital, the Italian Hospital, the German Hospital and various private clinics and universities with specialized services. The Argentine Glaucoma Association also offers information, awareness campaigns and guidance for patients.
Although hearing the word “glaucoma” can generate fear, ophthalmologists agree that, diagnosed in time and treated consistently, it is possible to maintain a good quality of life and slow the progression. The final message from the specialists is clear: sight does not hurt, but it is lost, and the only way to protect it is to consult professionals, have checkups and not abandon treatment. Early detection continues to be the best ally to buy time for “this silent thief” who, if confronted in time, can be stopped.
