Eye-health specialists said early diagnosis is the only way to control glaucoma and prevent irreversible blindness [1].

Because the disease often progresses without noticeable symptoms, detecting it while vision remains strong allows doctors to halt optic-nerve damage. This intervention is critical because once sight is lost to glaucoma, it cannot be recovered [1, 2].

In Brazil, more than two million people are affected by the condition [4]. This high prevalence has led to increased awareness campaigns, including "Brown April," which highlights the silent nature of vision loss [3]. Specialists said the disease can advance without warning, making routine checkups a necessity for all adults.

Dr. Jairo Mendes said, "It is essential that people have regular exams to detect glaucoma in the early stages" [1]. His warnings align with broader efforts across Portuguese-speaking regions to increase screening rates.

The Sociedade Portuguesa de Oftalmologia (SPO) also highlighted the importance of timing in treatment. The society said, "Early diagnosis in a phase where the person still has good vision is the best form of prevention" [2].

Medical professionals said the primary goal of early detection is to preserve the patient's current quality of life. One ophthalmologist said that early diagnosis can prevent the progression of the disease and preserve the vision of the patient [3].

Treatment typically involves managing intraocular pressure to protect the optic nerve. When identified early, these medical interventions can effectively stop the disease from reaching the stage of total blindness [1, 2].

“"It is essential that people have regular exams to detect glaucoma in the early stages."”

The emphasis on 'silent' progression indicates a public health shift toward proactive screening rather than symptomatic treatment. Because glaucoma damage is irreversible, the medical community is prioritizing population-wide awareness to reduce the long-term economic and social burden of preventable blindness.
