Sep 15, 2017 · The testing of the pupillary response to light is routinely performed by the eye care practitioner and imparts valuable information regarding the presence, laterality or magnitude of diseases that mainly affect the optic nerve, such as glaucoma. 1 A relative afferent pupillary defect (APD), when present, is an important marker in the evaluation ...
Aug 5, 2015 · The APT measures the pupils down to ±0.5 millimeter. You do not have to rely on approximations and pupil rulers anymore! The APT helps you provide better care to your patients. Serious problems can be detected if proper pupil testing is performed. The APT will help you ensure consistent APD testing and pupil measurement for all your patients ...
Sep 10, 2021 · Start with dim room illumination. Traditionally, the direct response and consensual responses of each pupil will be tested prior to performing the swinging flashlight test. Once direct and consensual responses are checked. Start with one eye and then swing your light source to the other eye.
The ‘swinging light test’ is used to detect a relative afferent pupil defect (RAPD): a means of detecting differences between the two eyes in how they respond to a light shone in one eye at a time. The test can be very useful for detecting unilateral or asymmetrical disease of the retina or optic nerve (but only optic nerve disease that ...

Dec 11, 2012 · Views 301. In this video demonstrates a new, more sensitive method for detecting subtle afferent pupillary defects (APDs): the magnifier-assisted swinging flashlight method (MA-SFM) using a +20 D lens. Cases of positive APDs are illustrated: an APD that is easily detectable by the conventional swinging flashlight method and cases of subtle APDs ...
Sep 15, 2008 · So, pupil testing can assess the amount of relative functional visual field between eyes. 5. Most commonly, the eye that manifests the RAPD has ipsilateral damage prior to the chiasm. For example, an RAPD may be due to an ipsilateral optic nerve glioma. In contrast is the unique example of an optic tract lesion.

May 15, 2015 · The equipment required to perform pupil testing is minimal: all you need is a millimeter ruler or pupillary gauge and a transilluminator (which is preferred over a disposable penlight due to the intensity of the light). Observing pupil shape, location, and size. A normal patient’s pupils should be round, symmetrical, and centered within the iris.
