Restoration of function following traumatic superior eyelid avulsion in a horse treated with advancement flap blepharoplasty (H-plasty) and subdermal hyaluronic acid filler.

Objective: To describe the successful restoration of superior eyelid function in a horse following traumatic avulsion using an advancement flap blepharoplasty and subdermal hyaluronic acid filler.

Animal Studied: A 21-year-old American Paint Horse stallion who was attacked by a fellow stallion resulting in numerous traumatic injuries including avulsion of approximately 75% of the left superior eyelid.

Procedures: With standing sedation and locoregional anesthesia, the superior eyelid wound was debrided and an advancement flap blepharoplasty (H-plasty) and temporary tarsorrhaphy were performed.

Osmolarity of basal and reflex tears of normal dogs.

Objective: To compare basal and reflex tear osmolarity in healthy dogs and to evaluate for correlation among tear film osmolarity, tear production, and tear fern pattern.

Animals Studied: The population consisted of 22 healthy adult dogs.

Procedures: Reflex tear osmolarity was measured in both eyes using the I-PEN  VET osmometer 30 minutes following the Schirmer tear test (STT-1) measurement.
