Theme: causes of pupil abnormalities

Options:

a. mydriatrics

b. myotics



Question: A 38 yr old man was recently started on treatment for depression. He now complains of blurred vision and is found to have small pupils.



(The answer is mydriatrics: as most of the tricyclic antidepressants have anticholinergic effect: hence mydriasis, but the patients pupil is 'small'...why?)
