Abstract
The measurement of the deviation of strabismus is usually performed by the prism cover test (PCT) and the synoptophore. The corneal reflex test (CRT) (Hirschberg test) has been used as an objective method of determining the angle of deviation. Recent papers (Brodie 1987, Carter & Roth 1978) have re-evaluated the CRT and proposed significantly different ratios (21–22 prism dioptres per millimetre). In strabismus clinics the CRT is frequently used with the patient wearing glasses. However, the corneal reflex test through glasses poses some problems. The reflections from glasses disturb the corneal reflexes. Glasses themselves have prismatic effects. Only one paper has mentioned the CRT through glasses.
