Earlier this week, our veterinary team removed the right eye of our milk snake, Milkshake, due to serious issues stemming from a blocked tear duct. Read more below to learn about Milkshake’s condition, the surgery that followed, and his recovery.

Last month, keepers noticed that Milkshake’s right eye was swollen. Further examination revealed that the snake had a blocked tear duct. Because snakes’ eyelids are fused together, it couldn’t drain on its own, which means pressure was building up between the eyelid and the patient’s eye. This pressure could lead to extreme pain and discomfort and ultimately blindness in that eye. Following their discovery, our animal care staff did a weekly draining of the tear duct using a fine needle, each time removing about 0.1 mil of fluid; this went on for a month.
In an effort to relieve the snake’s discomfort more permanently and reduce the stress caused by weekly draining, our animal care team made the decision to remove the eye. Milkshake was placed under anesthesia during the procedure. He received both numbing and pain medications, as well as epinephrine post-surgery to constrict blood vessels and slow bleeding.
Electrical probes inserted into the animal measured the conductivity of the heart, allowing our veterinary team to monitor Milkshake’s cardiac activity throughout the surgery and recovery.
An operating microscope capable of showing details as small as red blood cells moving within the eye vessels was used during the procedure.
The eye was removed with extreme care.
After the eye was removed, a gel foam sponge was inserted into the socket, helping to clot the blood and fill in the space. This will stay in place for the next 1-2 weeks.
We are pleased to report that surgery went well, and Milkshake is expected to make a full recovery. If you visit the GSC in the near future, you may notice his exhibit is lined with newspaper instead of soil. During recovery, this will prevent any debris from entering the surgical site as it heals.
