For anyone interested, this is what's wrong with my eye...
"glaucoma is a condition in which pressure inside the eye (intraocular pressure) is raised abnormally as excess fluid accumulates. It occurs when the normal outflow of fluid within the chamber of the eye (aqueous humour) is interrupted. As pressure rises, the optic nerve suffers irreversible damage, leading to a reduction in the field of vision and, ultimately, loss of eyesight."
Glaucoma is more common in people over 40, but "Congenital Glaucoma" - though more rare - can occur (obviously, since it's what I have). If caught early enough most types of Glaucoma are able to be at least stopped from progressing (well, in a lot of cases anyway) but not generally Congenital Glaucoma. As a general rule, the best you can hope for with Congenital Glaucoma is that you can find the right combination of medication (eye drops, etc) to buy you as much time with eyesight as possible.
