Supplementation of equine placenta extract on corneal wound in two dogs: Case report

Abstract

Background: Canine corneal disease is a common condition encountered in daily practice. If the depth of corneal damage is limited to the epithelial layer, healing is often straightforward; however, if it extends into the epithelial basement membrane or corneal parenchyma, surgical treatment is the treatment of choice. Moreover, in cases where there is underlying disease or where the owner refuses surgical treatment, treatment options are often limited to eye drop treatment, which may be inadequate. Case Description: Dogs aged 10 and 14 years were admitted to the hospital with eye injuries. Based on the examination findings, the owner believed that surgical treatment would be effective; however, this could not be performed owing to the underlying condition of the cases. Hyaluronic acid and antibiotic eye drops were administered, but there was no improvement in the eye damage. The eye-drop treatment prolonged without any improvement, and in the meantime the patients' weakness became apparent. In parallel with the eye-drop treatment, the patients were given a supplement containing equine placental extract to help restore their physical fitness. Consequently, in addition to the recovery of physical fitness, a film gradually formed over the eye damage area and injuries improved eventually. Conclusion: Based on these cases, supplementation with equine placenta extract may be an effective treatment option for ocular conditions that are difficult to treat surgically.
