“Glaucoma” in simple terms is called as “eye pressure”, which is caused by insufficient drainage of fluid called
aqueous humour within the eye, whose primary function was to maintain pressure within the eye and also to supply required nutrition to the lens
and the cornea. This accumulation of fluid (aqueous humour) within the eye, leads to raised eye pressure (intra-ocular pressure), which in
turn has a tamponade effect on the optic nerve, leading to development of glaucoma. This irreversible damage to optic nerve leads
to peripheral constriction of his/her field of vision, which eventually leads to tubular vision and vision loss.
