The aim of the present study is to verify whether a peripheral vasoconstriction is related to a change of the eye blood perfusion. This feature is indirectly evaluated measuring the variations of the ocular surface temperature (OST) by infrared thermography. For the experimental tests 45 healthy young subjects (mean age 25.4± 4.1 years) were enrolled, 35 men and 10 women. The test is repeated two times for each subject, with a 30 minutes spacing. Each acquisition is 40 s long, during which the subject immerses the hands in a tank with ice and water (1.6°±0.4°). In a single test the OST is registered during the first 10 s and during the last 10 s. Between the two registrations the subject maintains the eyes closed. So, the OST acquired at the beginning and at the end of the test were compared by a paired T∈-∈test. The data show a significantly OST increase (p
