Thursday night: understanding glaucoma

Diagram of the human eye.

Useful when trying to understand angle recession glaucoma for, say, a court case, hypothetically.

Here's what I've learnt: To test for glaucoma a fundoscopy is conducted. This is an examination of the back part of the eyeball (fundus)- which includes the retina, optic disc, choroids, and blood vessels. A high 'cup-to-disc ratio' (still don't actually know what that means) indicates pressure build-up inside the eye. Like too much air in a balloon, they say. The cause of this pressure build-up is blunt trauma to the eye, such as a car accident. However, to prove that a specific accident, which occurred years prior to the onset of noticeable symptoms, was in fact the cause of the said trauma which resulted in the said angle recession glaucoma, can be most difficult!
It could be, hypothetically, what looses you a court case. *hope not*
