someone had a really good mnemonic for the polyploidy's.. like trisomy 21.. the age you go drinking.. it goes DOWN hill - down's syndrome... then there were 2 more.. i would give anything if that person could repeat these..
glaucoma - too much pressure in aqueous humour
cataracks - the lens goes from clear to opaque.. because the sodium/potassium pumps stop working
astigmatism - wierd shape or something
myopia?
hyperopia?
