Why film maker need to go to a medical school

I like watching 'medical' scene in any Asian drama. They are absurd!

I was watching a drama circling around a life of the blind.

1st: Ophthalmologist can diagnose glaucoma just by doing visual acuity test. Where is your tonometer or at least slit lamp? Aqueous depth? Yes you can do that with primitive tools, but to come to a diagnosis, one have to have the intra-ocular pressure, unless if the person is already blind, by then the cause is apparent.

2nd: One can get blind from glaucoma. Yes indeed it is true, but iridectomy, is not that hard to do. One can just use laser beam to open up a hole. As long as the doctor detect it earlier.

In the drama, the diagnosis was done before the hero gone blind.

Asian drama... DRAMATIC! no wonder Asians are a bunch of paranoid and hypochondriac.
