The article addresses the increasing concern over glaucoma, a major cause of irreversible blindness, particularly in light of a rise in cases following the COVID-19 pandemic. In response, leading medical entities in Argentina are organizing a national day for free eye examinations on Friday, the 13th, across more than 130 institutions to ensure better access to eye care. The pandemic's impact on preventive consultations has resulted in a worrying spike in severe glaucoma cases, emphasizing the need for annual check-ups for timely diagnosis and intervention.

Glaucoma is caused by a dysfunction or blockage in the drainage of the aqueous humor, the fluid that nourishes the eye. This accumulation leads to increased intraocular pressure, which can damage the optic nerve and result in vision loss. The Argentine Council of Ophthalmology has characterized glaucoma as a 'silent thief of sight' due to its insidious progression and lack of early warning signs, often leading patients to perceive blurry vision only in advanced stages.

This national initiative aims to raise awareness about the disease and encourage regular eye examinations, as many individuals may be unaware of their risk or the necessity of routine checks. As healthcare providers push for more consistent screenings, the hope is to reverse the trends caused by the pandemic and reduce the incidence of preventable blindness through proactive healthcare engagement and education about glaucoma's risks.
