Modified Krimsky test for irregular scarred corneas.

The measurement of the amount and nature of deviation is the essence of diagnostic workup of a patient with strabismus and also has important therapeutic implications while planning the amount of surgery or prescribing therapeutic prisms. Although Krimsky test is a useful method, it cannot be used to measure deviation in patients with scarred and irregular cornea with an anechoic posterior segment making it difficult to see the corneal reflex. We hereby take the opportunity to present a modification of the original Krimsky test which is extremely helpful in determining the deviation in patients with irregular opaque corneas.
