Glaucoma is a leading cause of irreversible blindness worldwide. 

Glaucoma is a complex group of eye conditions characterised by damage to the optic nerve, which is responsible for transmitting visual information from the eye to the brain. The damage often occurs due to elevated intraocular pressure (IOP), leading to progressive vision loss and potentially irreversible blindness.^1,2,3,4 Globally, glaucoma affects an estimated 60 million individuals and stands as the leading cause of permanent vision impairment.⁴
