How to use a Welch Allyn Retinoscope?

Start by setting up your retinoscope by asking the patient to relax and look at a fixed point across the room. Dim the lights and sit an arms length away from them.

Begin with the retinoscope streak in a vertical position and direct the light into the patients right pupil, looking at the red reflex, before sweeping the retinoscope streak horizontally across the pupil. Rotate the retinoscope streak so it's horizontal and sweep across the pupil vertically. Repeat this with the retinoscope streak at a 45 degree and 135 degree angle.

Determine if the refractive error is spherical or astigmatic and the sphecrical compontent with various lenses roughly where a patients glasses would sit but keep the retinosope an arms distance away from the patient.

Double check the neutral point by observing reflex movement when moving forwards and backwards slightly at a normal working distance from the patinet. Finally look for refractive errors before performing the same examination on the left eye.
