What is the Krimsky method?

• A. A prism-adaptation method using prism to neutralize the deviation while viewing a light reflex to estimate angle of deviation.
• B. A refractive error measurement with a phoropter.
• C. A test to measure ocular dominance.
• D. A method to assess near point of convergence.

Answer: (B)

The Krimsky method is a prism-based way to estimate the angle of strabismus (the deviation) by neutralizing the corneal light reflex. The patient fixates on a target (often a distant light). You observe the corneal reflections in both eyes; if the eyes aren’t aligned, the reflections won’t sit at the same spot. A small prism is placed in front of the fixing eye and increased until the corneal reflections appear aligned between the two eyes. The strength of the prism required to achieve this alignment equals the angle of deviation, reported in prism diopters. This technique uses prisms to quantify the misalignment, not to measure refractive error with a phoropter. It’s especially useful when a full refraction isn’t feasible or when working with children or uncooperative patients. It does not assess ocular dominance or near point of convergence.
