World Glaucoma Day is observed globally on March 12 each year to raise awareness about glaucoma, a group of eye diseases that can lead to vision loss and blindness.
The day also marks the beginning of World Glaucoma Week, an initiative led by the World Glaucoma Association in collaboration with the World Glaucoma Patients Association.
The campaign aims to educate the public about glaucoma and encourage regular eye examinations, particularly checks that assess the health of the optic nerve.
Glaucoma, often referred to as “the silent thief of sight,” develops gradually and typically causes no pain in its early stages. Because symptoms may not appear until the disease has advanced, many people remain unaware they have it until significant vision damage has occurred.
The condition damages the optic nerve, which is responsible for transmitting visual information from the eye to the brain. Although the vision loss caused by glaucoma cannot be reversed, early diagnosis and treatment can help slow or stop the progression of the disease.
One of the most common causes of glaucoma is increased pressure inside the eye. This occurs when the eye’s natural fluid, known as aqueous humor, fails to drain properly. Normally, this fluid circulates in and out of the eye continuously. However, when the drainage system does not function properly, fluid builds up and increases pressure within the eye.
Over time, the pressure damages the delicate fibers of the optic nerve and as more nerve fibers are destroyed, vision gradually deteriorates, which can eventually result in permanent blindness if left untreated.
Early detection is therefore crucial, Regular eye examinations can help identify glaucoma in its early stages, allowing for treatment that can preserve vision and prevent avoidable blindness.
