This study presents an adaptation of the Brief Pain Inventory (BPI) extending its use in clinical/epidemiological contexts and the evaluation of the properties of BPI (short form) in a sample of Brazilian adults. ⋯ This study presents evidence related to the validity of applying the Brief Pain Inventory (BPI) in adults with and without pain considering the present pain or memory of pain, enabling the clinician to collect additional information that may be relevant to the clinical management of pain.

Ocular surface diseases are among the most frequent ocular pathologies. Ocular pain following corneal injury is frequently observed in clinic. Corneal sensory innervation is supplied by ciliary nerves derived from ophthalmic division of the trigeminal ganglion. ⋯ This study highlights the parallel increase in ciliary nerve activity and corneal sensitivity after corneal injury in mice. The strategy of combining ex vivo electrophysiological recordings of the ciliary nerve in mice and corneal sensitivity measurements therefore helps to uncover the functional aspects of corneal pain.
