Transpalpebral exenteration in cattle: a retrospective study of 115 cases

Abstract

Early clinical diagnosis of SCC by owners and veterinarians may prevent the need for exenteration. Owners should be made aware of the possible postsurgical complications following exenteration in cattle.

Eye enucleation and exenteration in ­cattle: a retrospective study of 38 cases (2013–2020)

“…Previous retrospective studies performed in the United States reported more than 80 % of cattle that underwent enucleation or exenteration were diagnosed with OSSC. 3,9 Instead, more than half of the cattle population (55,3 %) of the present study was diagnosed with non-neoplastic ocular lesions, represented mainly by severe trauma with loss of globe content. A possible explanation for this difference could be the absence of Hereford cattle, known as being predisposed to OSCC development, 1 in our study population compared to the above-mentioned reports.…”

“…Performing enucleation or exenteration under sedation and local anesthesia may significantly decrease the risks associated with general anesthesia, including regurgitation of ruminal content and occurrence of myopathies and neuropathies, as testified by other reports. 3,9 Despite the high proportion, none of the perioperative complications encountered in this study was considered life-threatening and none of the hemorrhages required blood transfusion.…”

“…2 Risk factors for OSCC development seem, therefore, comparable to those experienced in the United States. 3,9 It must also be considered that it is possible that a part of the cattle affected by OSCC is culled without hospital referral thus decreasing the perceived prevalence of the disease. On the other hand, the higher rate of traumatic ocular diseases found in this study may be explained by the fact that more than 10 % of the Swiss cattle population still wear horns, which increases risks for horn-induced injuries, including severe trauma with loss of globe content.…”

“…1,6 Common complications following these surgical procedures include surgical site infection (SSI), suture dehiscence, and progression/recurrence of neoplasia. 3,5,9 Neurologic signs due to optic nerve stretching, although rare, have also been reported. 6 There are multiple factors affecting veterinarians' and owners' decisions to proceed with enucleation or exenteration in ruminants.…”

Diagnosis and surgical management of a retrobulbar abscess causing unilateral exophthalmos in a Boer goat

“…No globesparing orbital exploratory procedures have been described in ruminants, where exenteration is more commonly used particularly when vision has been lost and restoration of patient comfort is paramount. 3,14,15,29,30 To the authors' knowledge, this is the first documented case report of a mixed bacterial retrobulbar abscess with intraocular extension in a goat, with advanced imaging and subsequent surgical management.…”
