While early-stage glaucoma patients may notice no decline in their sight, once their optic nerves are infected, their vision will gradually blur before eventually disappearing altogether. Known as ‘visual field defect’, this phenomenon can ultimately lead to permanent blindness in especially severe cases. One of the reasons glaucoma is called the ‘thief of sight’ is that most sufferers are only diagnosed during the disease’s moderate to advanced stages. As a result, early detection and diagnosis are vital.
Diagnosing Glaucoma
A major cause of irreversible blindness globally, glaucoma is often called ‘the thief of sight’ As the condition has no symptoms during its crucial early-stages, sufferers can still see normally. Tragically, as the disease progress, patients’ sight will gradually narrow to purely peripheral or central vision.

Diagnosing Glaucoma
• Optic nerve examination：Doctors using a professional fundus camera or other imaging technique will carefully examine patients’ optic nerves, including the shape, colour, and structure of their optic discs as well as any damage to the nerves themselves.
• Retinal thickness measurement：Advanced OCT technologies are used to identify changes in the eye’s retinal layers.
• Visual field measurement: One of the key benchmarks for evaluating glaucoma, this technique enables doctors to determine the type and extent of the patient’s glaucoma.
• Eye pressure measurement：While high intraocular pressure is a major indicator of optic nerve degeneration, such pressure is not always associated with glaucoma.
Is Glaucoma Curable?
Eye drops
Eyedrops or oral drugs are used to reduce intraocular pressure
Laser treatment
Laser trabeculoplasty and laser transscleral cyclophotocoagulation
Eye surgery
Trabeculectomy, catheter shunts, and minimally Invasive glaucoma surgery
