Krimsky test/ Modified Krimsky test 

This video is about krimsky test which is done to measure the amount of tropia. In krimsky test we use prisms to center the corneal light reflex in the deviating eye. '
In krimsky we use prisms in front of deviating eye.
In modified krimsky we use prisms in front of the fixating eye.
The most accurate way of measuring the amount of deviation is by the prism cover test. But it needs good cooperation,proper fixation and good visual acuity. So krimsky test is done in case where the prism cover test cannot be performed.
Thanks for watching.
