Reactivity may be:Īt the same time look for the normal pupillary constriction response in the opposite eye. Instead, position yourself in front of the eye and shine the beam from slightly off to one side.ĭocument pupil reactivity to light separately. Tip: shining the torch onto the pupil from directly above may make assessment difficult due to ‘glare’ reflected off the cornea. The pupil response to light is assessed by shining a neuro torch (or low powered penlight torch) separately into each eye. They may still react to light but usually the reactivity is sluggish. Keyhole pupils are seen in patients post iridectomy (a common part of cataract surgery). Oval pupils may be a result of compression of the III cranial nerve as a result of raised intracranial pressure (ICP).Īs ICP increases, the pupil will continue to dilate and eventually become non-reactive to light. Causes of irregular pupils include cataract surgery or the implantation of intra-occular lenses. The pupil shape can be documented as round, irregular, oval or keyhole. This difference should not be greater than 1mm and pupil reactivity should be normal. You may also find it useful in your written documentation to include descriptors such as: pinpoint, small, midposition, large, dilated.Īnisocoria: Up to 20% of the population have a slight difference in pupil size and is considered a normal variant. Tools to help you estimate this size include pupil gauges located on most Glasgow Coma Scale records and many neuro torches. ![]() The pupil size is documented as the diameter in millimetres.
