OPHTHALMOLOGY / NEURO-OPHTHALMOLOGY / NEUROLOGY
The NeuroLight, a small pupillometer, allows a thorough examination of the pupil and its dynamics with great precision. It is the only pupillometer equipped with a telecentric optical system which does not require any calibration step or compensation of the measurements according to the physiognomy of the patients. The measurements taken are absolute measurements and do not depend on the operator.
From the study of the direct or consensual photomotor reflex to precise measurements of anisocoria and pupil deformation under different light conditions, many possibilities are available to practitioners. Its use makes it possible to optimize and quantify precisely the damages linked to pupillary syndromes such as Addie’s syndrome, Argyll-Robertson’s sign, Claude Bernard Horner’s syndrome,…
NeuroLight’s computing power also makes it possible to analyse and record eye movements in order to extract nystagmus and calculate their frequency and speed.
It should be noted that the measurement accuracy and the calculated parameters allow a fine exploration of the autonomic nervous system via pupillary reactivity. Indeed, we know that changes in the ANS (Diabetes, Alzheimer…) will affect pupil dynamics:
- Decreased magnitude of contraction
- Extended latencies
- Decreased contraction speeds
- Redilation speed reduced
REFRACTIVE SURGERY / PUPILLARY MEASUREMENT
NeuroLight offers fast and accurate measurement of the maximum/minimum diameter and instantaneous measurement of the pupil under photopic, mesopic and scotopic light conditions.
The importance of pupil size before refractive surgery has been demonstrated by several studies (Pupil size and night vision disturbances after LASIK for myopia, Night Vision Disturbances After Corneal Refractive Surgery, …).
Measurement of pupil size under different light conditions is essential information in the management of patients undergoing refractive surgery. The measurement of the pupil in scotopic condition makes it possible to formalize possible problems of alteration of night vision after surgery.
The STA-W1 charging station makes it easy to recharge the NeuroLight in ophtalmology at any time.

"Melanopsin-Mediated Acute Light Responses Measured in Winter and in Summer: Seasonal Variations in Adults with and without Cataracts"
Mirjam Münch, Myriam Ladaique, Ségolène Roemer, Kattayoon Hashemi, and Aki Kawasaki
Seasonal adaptation is a ubiquitous behavior seen in many species on both global hemispheres and is conveyed by changing photoperiods. In humans this seasonal adaptation is less apparent, in part because changes in daylength are masked by the use of electrical lighting at night. On the other hand, cataracts which reduce light transmission, may compound seasonal changes related to the reduced daylength of winter. To better understand the effects of different photoperiod lengths in healthy adults without and with cataracts, we tested their melanopsin-mediated light responses in summer vs. winter…
