The Pupillary Light Reflex (PLR) is the involuntary movement of the pupil adapting to lighting conditions. The measurement and qualification of this information have a broad impact in different fields. Thanks to technological advancements and algorithms, obtaining accurate and non-invasive records of pupillary movements is now possible, expanding practical applications.

Analyzing human pupillary behavior is a non-invasive method for evaluating neurological activity. This method contributes to the medical field because changes in pupillary behavior can be correlated with several health conditions such as Parkinson, Alzheimer, autism and diabetes. Analyzing human pupillary behavior is simple and low-cost, and may be used as a complementary diagnosis.

Methods: Cross-sectional study of 20 eyes (18 patients) with zone 2 and 3 toxoplasmic scars and visual acuity ≥20/25. Patients underwent Humphrey 10-2 perimetry, contrast sensitivity (Mars test), and color vision testing (L'Anthony desaturated D-15).
Purpose: To analyze the clinical and epidemiological characteristics of patients with uveitis in an emergency eye care center.
Methods: We conducted a prospective, observational study of patients with active uveitis admitted between May 2012 and July 2012 to an emergency eye care center.
Results: The majority of patients were male (63.
