Pupillometers — effective vision diagnostics

Ophthalmologic examination of patients includes one of the stages — determining the width of the pupils and their distance. These indicators are necessary for the production of glasses that correspond to the anatomical features of the eye structure and do not cause physical intolerance or discomfort. To determine these results, a special device called a pupillometer is used, which can be easily purchased on the Bimedis Marketplace.

Features of using a pupillometer

Pupillometers are divided into two types: mechanical and digital. Mechanical in modern medicine are rarely used. The devices involve the use of special stencils by the doctor to measure values. The technique is inaccurate, has an error of up to 0.5 mm, and also requires sufficient experience of the specialist. Digital pupillometer from a leading manufacturer is characterized by high accuracy. Key functions of the equipment:

1. Fixation of the distance from the pupil.

2. Evaluation of vision parameters during alternate gaze at objects in the distance or near.

3. Determination and accounting of pupil reaction to light.

The device has an automatic mode of operation. Each pupillometer has a manual with recommendations for operation from the manufacturer. To begin work, the doctor must study the requirements for use. Thanks to clear compliance with the rules, the specialist can obtain accurate data on each patient.

Conducting measurements with the use of pupillometry

Before diagnosing with a pupillometer, there is no need for special preparation. To start the study, it is necessary to take a sitting position, remove contact lenses, glasses. The ophthalmologist puts the device of mechanical type on the bridge of the patient's nose and registers the indicators several times for reliability.

The digital device provides fixation of the chin and forehead. The patient's gaze should be directed forward. The device takes measurements, displays them on the display and prints them out if necessary. It is forbidden to make head movements during the measurements. As a result of the digital study of pupillometry, the doctor has data:

• the gap between the centers of the pupils;

• distance from the center of the bridge of the nose to the center of the pupil;

• vertical and horizontal pupil diameter;

• estimation of the amplitude of change in pupil size;

• time, speed of constriction when exposed to light.

Devices of improved models allow to record and analyze pupil reaction to stimuli. The examination does not require the introduction of anesthetic drugs and lasts only a few minutes without unpleasant sensations. The devices help to take into account individual features of the visual apparatus, which is important when choosing glasses.
