Pupillographs measure the size of the pupil in response to a light stimulus. The word "pupilogram" comes from the Latin word for pupil, and it is a combination of the terms, 'pupil' and 'graph'. The term was first used in 1885 in the Archives of Neurology and Psychiatry. The term "puppillogram" has been around for about 70 years.

In 1956, Lowenstein and Loewenfeld developed a device called the Electronic Pupillograph. It was a prototype of the instrument used to measure the size of the pupil. The figure below shows a typical curve of the signal output from this device. The measurements were made by a single eye. These instruments have become increasingly popular as a tool in the diagnosis and treatment of a variety of diseases and conditions.

The RAPDx device analyzes the pupil responses and helps to diagnose a variety of important conditions. The RAPDx can also be used in clinical studies and to study the ANS. Besides clinical use, IR video pupillography is becoming an increasingly popular tool in neurological research. In Alzheimer's disease and Parkinson's disease, the cholinergic system is affected, resulting in an altered pupil response.

In 1956, Lowenstein and Loewenfeld created the Electronic Pupillograph. This instrument was a prototype for the actual instrument used for the study of the human pupil. The figure above shows the typical curve of the output signal for this instrument. It was designed by Fotiou and Loewenfeld. It was the first electronic Pupillograph. The other instruments are more sophisticated and include a stimulator, amplifier-detector assembly, and a display unit.

The Pupillograph market is growing globally. The main reason for its growth is the fact that it can monitor the health of a patient. It can detect eye diseases, and it can also diagnose a number of other medical conditions. In the United States, the market for Pupillographs is valued at $571 million in 2016. In addition to this, it has a significant international market share. The U.S. is the largest consumer of Pupillographs.

While Pupillographs have been used in medical fields for centuries, their most common application is for research. The devices measure pupil responses to a monocular visual stimulus, such as a light source. The result of the test is an accurate measurement of both eye movements. These results are critical for determining the effectiveness of treatments and can be used to diagnose various diseases.

In recent years, the development of portable, high-quality infrared video instruments has enabled the use of Pupillographs in clinical settings. The device is also used to measure the diameter of the pupil for refractive surgery, to distinguish Horner syndrome from physiologic anisocoria, and to quantify the relative afferent-pupillary defect. The method is also used for determining sleepiness or to assess the autonomic effects of new pharmaceuticals.

Historically, the use of Pupillographs has been limited to research. The technology used for the instrument is highly sensitive and can detect any number of subtle changes. Moreover, the technique can be used to monitor the sensitivity of eye movements. Nevertheless, some clinical applications are based on Pupillographs for research purposes, despite the fact that some studies don't include these tests. In addition to visual reflexes, it is important to assess the function of the pupil in order to identify the cause of the changes.

A pupillograph is a device that generates pairs of simultaneous biometric waveforms representing average pupil responses to monocular stimuli. The waveforms are parsed by software into various metrics. The median value is derived from a set of repeated measurements to minimize noise. The most common parameters include resting pupil diameter, amplitude of the constriction, and latency of onset and recovery. The data collected can be used to detect any abnormalities.

In addition to measuring the intensity of a light stimulus, a pupillogram can also determine the severity of a person's eye condition. One such study involved a cohort of adults with suspected delirium who had not achieved a previous functional level and had no obvious clinical symptoms of status epilepticus. Although the study included patients with a range of different diagnoses, the authors conclude that the technique has great clinical utility for detecting seizures in these patients.
