“…Occasionally, the use of neck scruffs to restrain small breed of dogs may result in temporary proptosis (Mandel, 2000). In other breeds of dogs and cats, proptosis may develop due to violent head trauma as seen in automobile accidents, fights and scratch around the ocular region, resulting in ocular misalignment or displacement (Wheler et al, 2001;Subramanian and Birdsong, 2008;Lando et al, 2017). The effects of these traumatic changes include; inflamed periorbital tissues (which ultimately reduce the viability of the globe), corneoconjunctival desiccation, ulceration, orbital fracture and blindness (Wheler et al, 2001;Crispin, 2005).…”

Background: Traumatic proptosis is an ophthalmic emergency of concern in companion animal clinical practice, most breeders in Nigeria keep dogs in poorly organized facilities which often results in dog fights hence varying degrees of facial trauma occurs. This is becoming popular and one of the common causes of blindness in dogs. This study reports a case of dog fight which elicited acute traumatic proptosis of the right eye in an eight-week male Boerboel puppy. This was presented at Veterinary Teaching Hospital, University of Ibadan with a proptotic right eye. History revealed that the trauma was caused by an adult male dog kept in the same kennel. Physical and clinical examinations revealed pronounced rostral protrusion of the globe however, the retrobulbar trunk was intact, despite being swollen, it was still firmly attached to the eye socket. There was no visible injury to the globe. Hemogram revealed mild hemorrhagic hypoproteinemia, adequate platelet counts, and normal leukogram thus surgical intervention was not contraindicated. Tramadol (4mg/kg) was administered intramuscularly, proptosed eye was kept moistened with sterile isotonic solution and cold pack. Globe replacement, lateral canthotomy and temporary tarsorrhaphy were performed under deep sedation with xylazine/atropine and local block via infiltration of lidocaine (10mg) around the upper and lower orbital regions. This case report describes the surgical management and outcome of severe traumatic proptosis of the right eye despite highly displaced globe, intact retro bulbar trunk and timely presentation. The surgical intervention provided cosmetic result and alternative to enucleation of the entire eye structure.

“…In veterinary medicine, ocular injuries caused by traumatic accidents include corneal laceration, iris prolapse, and proptosis (6,7). Ocular misalignment can occur due to orbital fracture, nerve damage, or muscular damage (8)(9)(10). Although anatomical restoration has been performed in humans, strabismus with ocular misalignment has been difficult to correct in dogs because of anatomical and technical limitations (11).…”

“…In the case presented, we considered whether the proptosis could be induced by damage to the medial rectus muscle (MRM). Ocular misalignment, such as strabismus or proptosis after trauma, may develop from orbital fracture, muscular damage, and/or nerve injury (9,10). In dogs, acquired proptosis with damage of MRM may develop from proptosis secondary to blunt head trauma (11).…”

Case Report: Surgical Treatment of Severe Facial Wounds and Proptosis in a Dog Due to a Traffic Accident

Although facial wounds caused by traffic accidents in dogs are common, the surgical management of severe facial injuries involving the soft tissue, bone, dentition, nose and orbit are challenging. A 2 year-old Korean Jindo dog was diagnosed with severe skin defects of the face and proptosis caused by a vehicular accident. Along the left lateral maxilla, severe injury involving the overlying skin and platysma muscle occurred, to the extent that the middle part of the sphincter colli profundus pars intermedia muscle was exposed. Repair surgeries of the skin defects and globe displacement were performed using a local subdermal plexus rotation flap and a partial transposition of the dorsal rectus muscle combined with small intestinal submucosa (SIS) instead of enucleation as the first attempt. SIS was used to sustain the torn medial region. In this case, the surgery resulted in good cosmetic and functional outcome in the dog, despite the atypical complexities upon presentation.

A 37-year-old man suffered a penetrating left orbital injury with rupture of the inferior rectus muscle and avulsion of the optic nerve. The orbit was explored and the inferior rectus muscle stump was identified 25 mm from the limbus. Despite this, the muscle was successfully reattached and the patient achieved satisfactory postoperative alignment. [ J Pediatr Ophthalmol Strabismus . 2019;56:e49–e52.]
