Hirschberg & Krimsky Test — Strabismus Angle Estimation
Bedside estimation of ocular deviation when prism cover test is impractical (uncooperative child, dense amblyopia). Hirschberg: corneal light reflex displacement from pupil centre; each 1 mm ≈ 7° (≈15 prism dioptres / 15Δ). Krimsky modifies by adding prisms over fixing eye until reflex is centred.
