###Rationale: Hirschberg corneal reflex test: It is a rough but handy method to estimate the angle of manifest squint. In it the patient is asked to fixate at point light held at a distance of 33 cm and the detion of the corneal light reflex from the centre of pupil is noted in the squinting eye. Roughly, the angle of squint is 15deg and 45deg when the corneal light reflex falls on the border of pupil and limbus, respectively. Ref:- A K KHURANA; pg num:-327
