[Pain in Ophthalmology].

The pain, one of the most common and unpleasant symptoms of human experience, is a psychophysiological phenomenon made of physical (elementary) pain and psychological pain. The ocular pain may result from stimulation of trigeminal nerve fibres anywhere within the eye, the surrounding tissues, the deep orbit, and the base of the middle and anterior cranial fossae. An ocular pain which is accompanied by another ocular signs can easily suggest a diagnosis for ophthalmologist, but a deep pain which involves the frontal bone and the deep orbit often asks an interdisciplinary consultation.
