Study Notes
Surgical Approach and Anesthesia
- 31 cases used a transpalpebral approach, while 5 cases used a subconjunctival approach for enucleation.
- Anesthesia was not specified in 2 case histories.
Anesthesia Techniques
- General anesthesia was used in 35 cases (97%), often combined with regional anesthesia in 31 cases (89%).
- Sedation with regional anesthesia was used in 1 case, while 2 cases did not report anesthesia techniques.
Regional Anesthesia Methods
- Peterson block (14 cases) or 4-point retrobulbar block (16 cases) were used for regional anesthesia.
- Auriculopalpebral block (12 cases) and/or local infiltration of eyelids (8 cases) were also used.
Anesthesia Complications
- Anesthesia-related complications occurred in 12 cases (33%).
- Complications included regurgitation of ruminal contents (6 cases), inadequate anesthesia or sedation (5 cases), and severe bradycardia (4 cases).
Post-Operative Care
- Systemic antibiotics and NSAIDs were administered in 37 cases for 6±2 days and 5±2 days, respectively.
- The hospital stay after surgery lasted 8±6 days.
Complications and Recurrence
- Post-operative complications occurred in 11 cases (29%), including 9 cases of ischemic syndrome and 3 cases of recurrent COCE.
Discussion
- Non-neoplastic ocular diseases appear to be a more common indication for enucleation or exenteration in cattle in Switzerland compared to previous reports.
- More than half of the bovine population (55.3%) in this study was diagnosed with non-neoplastic ocular lesions, mainly severe traumatism with loss of ocular content.
Breed-Specific COCE Susceptibility
- The lack of Hereford breed in the study population may contribute to the difference in COCE prevalence compared to previous reports.
- The Hereford breed is known to be predisposed to COCE development due to genetic and hereditary factors.
Environmental Factors
- High levels of ultraviolet radiation in Switzerland, particularly during summer months, may contribute to the development of COCE in susceptible breeds.
