Bangkok: Glaucoma, often referred to as the "silent killer of the eyes," poses a significant threat to vision, often showing no early symptoms before advancing to irreversible blindness. According to Thai News Agency, this condition is the leading cause of blindness both in Thailand and globally, with an estimated 10,000 Thais losing their vision permanently each year due to glaucoma.
Glaucoma occurs when increased pressure in the eye damages the optic nerve, leading to a gradual loss of sight. This progressive deterioration often goes unnoticed until it reaches an advanced stage, at which point vision loss is irreversible. Early symptoms may include seeing a rainbow-colored halo around lights, followed by narrowing of the visual field and eventual loss of central vision. Current treatments aim to slow the disease's progression by lowering intraocular pressure, but they cannot restore lost vision.
To tackle the challenge of early detection, a groundbreaking initiative known as the "Dream Project" has been developed in Thailand. This innovative screening method combines retinal imaging technology with artificial intelligence (AI) to assess clinical risk factors such as age, intraocular pressure, and medication history. The system significantly improves detection accuracy, achieving a rate of 98.9%, compared to the 80% accuracy of previous methods. The Dream Project has garnered international recognition, winning the Best Invention Award from the National Research Council of Thailand and receiving accolades at an international innovation competition in Poland.
Despite having only about 2,000 ophthalmologists for the 30 million Thais at risk aged 40 and above, the Dream Project aims to overcome this limitation and enhance screening capabilities. A pilot test is currently underway at Thammasat University Hospital, with plans to expand access to remote areas in collaboration with the Ministry of Public Health.
In addition to technological advancements, ophthalmologists recommend regular self-screening to prevent vision loss. Individuals are advised to check their eyesight monthly using simple home methods, such as observing a calendar with numbers from a distance and comparing clarity between eyes. High-risk groups, including those over 40, individuals with a family history of glaucoma, and those with underlying medical conditions such as diabetes, are encouraged to consult an ophthalmologist annually.
In summary, glaucoma remains a significant yet silent threat to vision. Early detection through innovations like the Dream Project, combined with regular self-monitoring, is essential to preserving good eyesight throughout one's life.
