Glaucoma Diagnosis and Treatment - Dr. Rajesh Mishra at AEHI, A Unit of Dr Agarwals Eye Hospital 

Glaucoma is an eye disorder which leads to progressive damage of the optic nerve in a characteristic pattern. The optic nerve is involved in carrying the visual impulse from the retina to the brain enabling us to see this impulse as vision. Glaucoma is generally but not always caused due to increase in the eyeball or intraocular pressure; in few glaucoma may be caused with normal eye pressure.
