Surgical management of proptosis by globe replacement in shih-tzu dog-a case report

A four-year-old male Shih-Tzu dog weighing 8.1 kg was presented with an acute history of traumatic proptosis of the right eye following a dog fight. General physical examination revealed that all the physiological parameters were within normal limits. Upon detailed ophthalmic evaluation demonstrated absence of pupillary light reflexes along with severe injury to the extraocular musculature, indicating significant ocular trauma. The dog was premedicated with butorphanol and general anesthesia was induced using a combination of propofol and diazepam, followed by maintenance with 2% isoflurane in oxygen. Surgical management involved replacement of the prolapsed globe and stabilization using temporary tarsorrhaphy. Postoperatively, dog was managed with topical antibiotic eye drops, systemic antibiotics and anti-inflammatory medications for seven days and an Elizabethan collar was applied to prevent self-trauma. Sutures applied to the eyelids were removed on the fourteenth postoperative day. Dog showed an uneventful recovery with successful retention of the globe and only mild strabismus was noticed.
