Glaucoma is often referred to as the "silent thief of sight" because it typically develops gradually without noticeable symptoms in its early stages. Regular eye check-ups are crucial for early detection and prevention of irreversible vision loss.
Glaucoma is associated with increased intraocular pressure (IOP), which can damage the optic nerve. However, not all cases of glaucoma involve elevated pressure, and normal-tension glaucoma is a variation where optic nerve damage occurs despite normal IOP.
There are various types of Glaucoma, with the most common being Primary Open-Angle Glaucoma (POAG) and Angle-Closure Glaucoma. Each type has distinct characteristics and may require specific approaches to treatment.
Age, family history, elevated intraocular pressure, ethnicity (African Americans and Hispanics are at higher risk), and certain medical conditions such as diabetes and heart disease are considered risk factors for developing Glaucoma.
While Glaucoma cannot be cured, early detection and management can help slow down its progression. Treatment options include prescription eye drops, laser therapy, and surgical procedures to lower intraocular pressure and preserve vision.
In advanced stages, Glaucoma often leads to peripheral vision loss, creating tunnel vision. Regular visual field tests can help detect such changes.
Glaucoma is a global health concern affecting millions of people. The World Health Organization recognises its significance, and efforts are ongoing to raise awareness, improve early detection, and enhance treatment options worldwide.
