Glaucoma: Why is it so difficult?

Glaucoma is an eye disease

with elevated intraocular pressure, which

can cause damage to the optic nerve. Pupil dilation is caused by the use of drugs to dilate the pupils of the eye, usually used for eye

examinations or treatments. However, in glaucoma patients, pupil dilation drugs may increase the resistance to aqueous outflow, causing a further increase in intraocular pressure, which can exacerbate glaucoma.
