Multiple Choice Questions (MCQs) in Optometry and Ophthalmology

Well,  if you are a recent graduate of optometry (and or vision science), PCL ophthalmic science or ophthalmology; and if you are thinking of upgrading your career, then you are at the right place. Please go through each question and practice similar questions more. Hence this page is dedicated to career-oriented optometrists, ophthalmic assistants and ophthalmologists who want to refresh their knowledge in core theories of ophthalmology and optometry.

Who will be benefited by reading this MCQs in Optometry and Ophthalmology?

It will benefit those who-

a)            are appearing in licensing examination of pertinent council (health professional council,  optometry council or medical council)

b)           are appearing in the entrance examination for Master of Optometry

c)            are fighting for an optometry job, ophthalmic assistant job or ophthalmology job and have to appear in a competitive written examinations (for example: eye hospitals, Nepal Army, Nepal police, Lok Sewa Ayog, etc)

d)           All types examinations in the field of eye care that encompasses MCQs

e)            Viva voce examinations of Ophthalmic Assistants, Optometrists and Ophthalmologists

My advice: first go through the questions serially from question number one and try to answer them by writing the correct answer (that you think) in a separate paper. And after finishing, you can compare your answers with the ones given at the end of this page. You have to go to the specific textbook to look for the explanation so that you will be able to answer similar questions in the given contexts.
