Types of Pupilometer

 

Eye PD Meter

Pupillary Distance And Height Tester

This pupillary distance and height tester is made up of a high-quality ABS material that can withstand various external factors. It is compact and portable, making it easy to use in various locations. The device works by measuring pupil height and distance. Accurate results could be got quickly and efficiently.

Pupillary Distance Meter

Pupil Distance Meter

The pupil distance meter is a measuring instrument used to measure the distance between the two pupils of the human eye during optometry.

Pupillary Distance and Height Tester

Eye PD Meter

Compared to the traditional PD ruler, the digital eye PD meter offers the convenience of obtaining PD data within a few seconds without requiring a light pen.

 

Precautions For Using Pupilometer

Subject cooperation
The accuracy of the pupilometer depends on the subject’s cooperation and ability to focus on the target provided by the device. Distractions, discomfort, or anxiety may lead to inaccurate measurements.

Accuracy

Pupilometer accuracy may be affected by several factors. However, only accurate measurements can lead to correct diagnosis or treatment.

Ambient light

The ambient light in the environment can impact pupil size measurements. Controlled lighting conditions should be consistent during the assessment.

Eyelid interference

In some cases, subjects may have difficulty maintaining an open eye, or the eyelids may partially cover the pupil, leading to inaccurate measurements.

Ocular conditions

Certain ocular conditions, such as corneal opacities, cataracts, or severe ptosis, can interfere with the accuracy of the measurements.

Pupil size variation

Some individuals naturally have smaller or larger pupils, which can lead to difficulty obtaining accurate measurements.

Medications and substances

Some medications and substances, such as alcohol or illicit drugs, can influence pupil size and reactivity, potentially affecting the accuracy of the measurements.

How A Pupilometer Works

A pupilometer measures the distance between the pupils by using reflections of light. You will hold up the pupilometer like binoculars and look inside of it. You will see a green light. The optician will look through the other side of the device to see your eyes. The front of the eye, known as the cornea, reflects light. The optician will use a ruler to measure how far apart your corneal light reflections are. This measurement provides the pupillary distance.

FAQ

 

Q: What is the use of pupilometer?

A: The pupilometer is a hand-held instrument which provides quantitative pupillary measurements by taking 30 pictures per second of the pupil's response to light stimulus.

Q: How to interpret pupilometer?

A: Using its patented algorithm, the pupilometer assigns the PLR an objective neurological pupillary index value. NPi values range from 0 (non-reactive) to 5 (normal). An NPi value < 3 is considered abnormal and a value ≥ 3 is normal .

Q: How do you take near PD with a pupilometer?

A: Subtract 3 mm from your distance PD. For example, if your distance PD is 63mm, then your near PD is 60mm. If you use dual PD to calculate near PD, then subtract 1.5mm from each eye's measurement. For example, if your dual PD is 33/31mm then your near PD would be 31.5/29.5mm.

Q: What do the numbers on the pupilometer mean?

A: Dual PD measures the distance between the center of each pupil to the bridge of the nose. That means this measurement has two numbers—the first number is the measurement for the right eye (OD), and the second is for the left eye (OS). A dual PD measurement is usually written like this: 31/30.

Q: What are the advantages of a pupilometer?

A: With a pupilometer, a doctor can take a rapid and reliable measure of pain, leading to earlier, more effective treatment and reducing impact and cost. Pupillometry might be used to enhance athletic performance.
