The Gauteng Health department has appealed to residents to take care of their eye health seriously, to avoid glaucoma which might lead to blindness.
The department’s appeal comes as it marks World Glaucoma Day today, which is one of the leading causes of irreversible blindness.
Glaucoma, often referred to as the “silent thief of sight,” develops gradually without obvious symptoms until significant vision loss occurs.
According to the World Health Organization (WHO), glaucoma is a major global public health concern, particularly in Africa, where access to early detection and treatment is limited.
Research published in the South African Medical Journal indicates that the prevalence of glaucoma in South Africans aged 40 and above ranges from 4.5% to 5.3%, with primary open-angle glaucoma (POAG) being the most common form.
The study also found that 87% of individuals with POAG were previously undiagnosed, underscoring the need for regular eye check-ups.
Glaucoma is caused by damage to the optic nerve, often linked to increased eye pressure, and if left untreated, it can lead to permanent blindness.
According to the department, while anyone can develop glaucoma, people over 35, diabetics, those with a family history of the disease, and individuals with extreme near-sightedness are at greater risk.
“The department is actively working to combat preventable blindness through free eye screenings and treatment at public health facilities across the province.
Between April 2024 and January 2025, more than 2 000 patients were diagnosed with glaucoma at primary healthcare clinics and referred to hospitals for specialised care.
The department has also strengthened optometry services at health facilities, ensuring residents have access to screenings, prescription eye drops, laser procedures, and surgical interventions where necessary,” said the department spokesperson, Motalatale Modiba.
The department has encouraged the public to take advantage of the free screening services available at public health facilities to safeguard their sight.
