Pupilometry

Pupillometry is a test that allows knowing the size of the pupil and its response to certain stimuli.

During the exam, the patient should be in a dark room sitting with a straight back, eyes open, head steady, and most importantly, avoid blinking.The infrared pupillometer is then placed in the patient's line of sight while keeping the eyes on a fixed, distant point.

When doing a pupillometry, it is important to avoid noise, light and stress, as these factors can interfere with the results of the diagnostic test.

What is it for?

The main objective of polymetry is to study the size and reactions of the pupil to certain stimuli.

The results of this test will allow us to know the neurological disorder of a patient to diagnose or evaluate diseases such as Alzheimer's, migraine, Parkinson's disease and sleep disorders.In addition to the above, pupillometry is also measured in ophthalmology when a patient is going to undergo refractive surgery or we are going to implant intraocular lenses. In these cases, the measurement of the pupil is an essential value for the surgeon to plan the surgical procedure to be performed.

Pupillometry allows the following results to be analyzed:

Parasympathetic function parameters
Sympathetic function parameters:

With what instruments is pupillometry performed?

 To perform a pupillometry there is a wide variety of systems ranging from the classic rulers to pupillometers with infrared light.

 Currently, pupillometers with infrared light are the most modern and accurate equipment to measure the pupil, since they work in the dark through the inclusion of light sources that illuminate the pupil, but do not cause it to contract.

 Pupillometry can also be carried out by a topographer, as they contain special software that allows the pupil to be evaluated. However, not all surveyors can do a pupillometry.

 There are other equipment to measure the pupil that, in addition to evaluating the pupil reaction to the presence and absence of light, records them at the same time that it measures the pupil during the stimulus.
