Which statement about Mohindra retinoscopy is NOT true?

• A. It is performed 50 cm away in the dark
• B. It is a binocular method
• C. 1.25D is subtracted from the sphere power of the calculation
• D. It is a type of dynamic retinoscopy

Answer: (B)

Mohindra retinoscopy is a noncycloplegic, infant-friendly approach performed at a fixed working distance of 50 cm in a dim room to help relax accommodation. The reflex is assessed for each eye separately, with the other eye typically occluded, and then a subtractive correction of 1.25 diopters is applied to the final sphere value to account for the 50 cm working distance and the small amount of tonic accommodation in infants. Because testing is done monocularly, it is not a binocular method. The other details—performing at 50 cm in the dark and subtracting 1.25 D—are accurate aspects of the technique.
