- Ask the patient to follow your finger as you bring it toward the bridge of his nose.
- Note the convergence of the eyes and pupillary constriction.
How do you check pupil convergence?
Measure the near point of convergence (NPC). The examiner holds a small target, such as a printed card or penlight, in front of you and slowly moves it closer to you until either you have double vision or the examiner sees an eye drift outward.Jul 16, 2020
What is normal pupil accommodation?
The normal pupil size in adults varies from 2 to 4 mm in diameter in bright light to 4 to 8 mm in the dark. The pupils are generally equal in size. They constrict to direct illumination (direct response) and to illumination of the opposite eye (consensual responseconsensual responseA consensual response is any reflex observed on one side of the body when the other side has been stimulated. For example, if an individual's right eye is shielded and light shines into the left eye, constriction of the right pupil will occur, as well as the left.https://en.wikipedia.org › wiki › Consensual_responseConsensual response - Wikipedia). The pupil dilates in the dark.
How do you test for accommodation and convergence?
Testing for the accommodation reflex follows nicely on from eye movements. Ask the patient to keep focusing on the tip of your index finger and slowly move it towards them, aiming for the tip of their nose. You need to be watching their pupils to make sure you see them constrict as your finger gets closer.Aug 1, 2014
How do you test for convergence and divergence of the eyes?
To perform this test, a clinician will use a small penlight or other fixation target and then slowly move the light towards the patient. The patient is to report when the light breaks into two lights (double vision).
