A non-cooperative toddler has a suspected squint. The examiner places a prism bar in front of one eye and adjusts its strength until the corneal light reflex becomes centred in both eyes. Which test has been performed?
- A Krimsky test ✓
- B Hirschberg test
- C Bruckner test
- D Maddox wing test
Correct answer: A. Krimsky test
Explanation
The Krimsky test quantifies strabismus by placing prisms of increasing power before the fixing eye until the corneal light reflex is symmetrical and centred in both eyes. It is ideal for uncooperative children who cannot maintain fixation for prism cover testing. The Hirschberg test only estimates the angle from the degree of decentration without prisms. Bruckner is a red reflex test for detecting strabismus or media opacity, and Maddox wing measures heterophorias at near.
