What method is used to assess a cat's eye response during an exam?

The method used to assess a cat's eye response during an exam is typically through visual stimulation with toys, as it effectively engages a cat's natural hunting and playful instincts. This technique allows the examiner to observe how the cat's eyes react to movement and visual stimuli. By using toys that mimic prey movement, the clinician can assess the responsiveness of the cat's pupil and the overall eye function, which are indicative of a healthy visual response.

Other methods, while they may provide some information, do not assess the eye response as directly or effectively. Flashing a light may be more applicable in certain circumstances, but it can cause stress to some cats and might not provide as clear an indication of response as the interactive nature of using toys. Manual eyelid opening is invasive and typically doesn't reflect a true response, and waving a hand toward the eye may not produce a consistent or reliable reaction in terms of assessing eye health and function.
