Commercial amniotic membrane extract for treatment of corneal ulcers in adult horses.

Background: Amniotic membrane extract enhances the rate of epithelialisation after corneal ulceration in several species but has not been studied in the equine cornea.

Objectives: To evaluate the effect of amniotic membrane extract on re-epithelialisation of equine corneal ulcers compared with ulcers treated with antibiotic, antifungal and mydriatic medical therapy alone, and to evaluate equine corneal healing after experimentally induced superficial ulceration.

Study Design: Masked, randomised, controlled experimental trial.
