Examiner Preparation
- place instrument on the head placing most of weight on the crown strap
- tighten the crown strap & head band snugly but comfortably to fit the BIO like a baseball cap
- loosen & position the light tower/ocular assembly at the same level & as close to the eyes as
possible
- using a small target, perform a monocular PD alignment so that each eye sees the same field
- place the light source in the upper 1/2 of the imaged field: this allows the illuminating light
to enter the upper ½ of the pupil & the image light to emerge from the lower ½ of the pupil.
