What is Enucleation?
Enucleation is the surgical removal of an eye and its associated structures, e.g. eyelids. The procedure is undertaken in order to prevent pain or spread of disease, such as when an eye is irreversibly damaged, cancerous, or affected by non-responsive glaucoma.
Enucleation in dogs is often a treatment of last resort, when all previous attempts to salvage the eye have failed. The procedure is carried out under full general anesthetic and, although a major procedure, there is every chance of a successful outcome. This is not a specialist procedure and is commonly carried out at general vet practice.
Enucleation Procedure in Dogs
Enucleation is never undertaken lightly and only after all other treatment options have been explored. For example with glaucoma, referral to place a surgical stent (drain) in the eye may be an option.
Enucleation requires full general anesthetic and may involve an overnight stay after the surgery, for additional pain relief and monitoring. Elderly patients may require intravenous fluids during the surgery to reduce the risk of kidney complications.
The procedure involves:
- Preparing the patient by withholding food overnight prior to the operation
- A pre-op check, possibly including screening blood tests
- A premedication injection and pain relief to prepare the dog for the anesthetic
- The dog may be put on intravenous fluids at this point
- The anesthetic is administered via a catheter in the front leg and maintained via gas delivered through a tube in the airway
- A vet tech monitors the dog's vital signs
- Hair is carefully clipped from around the eye and face
- The skin is made sterile with surgical scrub
- The surgeon scrubs up, and then sutures the eyelids of the affected eye together
- The surgeon removes the eye by careful dissection, and any bleeding vessels clamped and tied off
- Skin is sutured over the empty socket
- The dog wakes from the anesthetic and must wear a cone to protect the surgical site
- The dog is discharged with pain relief and perhaps antibiotics
- The dog requires a post-op check at two to three days
- The sutures are removed 10 - 14 days later
Efficacy of Enucleation in Dogs
Once the initial post-operative discomfort is over, enucleation is extremely effective at preventing ocular pain, without risk of relapse. Many owners who opt for surgery after a delay often notice their dog is happier than it has been some time, now the long term low pain has gone. In many cases, the alternative to enucleation is long-term management of a condition, which can be difficult or even impossible to achieve. This may require visits to specialists for repeated anesthetics to repair damaged corneal tissue or regular visits to have the pressure within the eye measured. Medical management of severe eye conditions is rarely successful, which leaves the possibility that the dog is in constant low-grade pain, so treatment decisions are best made with the dog's long term welfare in mind.
Enucleation Recovery in Dogs
It is essential the dog wears a cone until the sutures are removed.
For the first two to three days postoperatively, the dog may be quiet from the anesthetic and experiencing some discomfort. The pain can be managed with medications, which your vet will supply.
Following a check-up at the two to three-day point, the dog has gentle lead exercise until the sutures are removed at the 10 - 14-day mark.
Complications are rare, but include hemorrhage or wound breakdown. If the bleeding is severe, revisional surgery may be required or the clinician may opt to pack the socket and use pressure to prevent further blood loss. However, the vast majority of patients make a full and uneventful recovery.
Once the sutures are removed no further aftercare is needed and the patient signed off.
Cost of Enucleation in Dogs
The one-off cost of enucleation surgery must be balanced against repeated specialist visits, repeated anesthetics, and ongoing medication costs. At a general practice, the cost of enucleation surgery ranges from around $400 - $950 depending on the supportive care needed.
Prescription eye drops for glaucoma cost around $15 -25 per bottle and may last around 2 - 3 weeks each. When a condition is managed medically the dog may need weekly visits initially and then three-monthly check-ups. The cost of these visits can be $25 - 50 for a regular vet, to $70 - $270 for a specialist veterinary ophthalmologist.
Dog Enucleation Considerations
There are many factors to consider with enucleation surgery. The procedure is permanent and irreversible, and the dog blind on that side afterward. However, many of the conditions for which enucleation is appropriate may have already resulted in loss of sight. The short-term discomfort of surgery is balanced against the long-term benefit of being pain-free. In addition, this surgical option can be cost effective as the results are permanent. The risks of surgery are low and relate to hemorrhage and any anesthetic risks for that individual patient. However, good surgical technique and pre-op screening minimizes both of these factors.
Enucleation Prevention in Dogs
Many of the health conditions that result in enucleation being an appropriate option are not preventable. Conditions such as glaucoma are strongly linked to genetic conditions such as luxating lens or poor drainage angles from the eye. Breeds most commonly at risk include terriers, Basset Hounds, and American cocker spaniels.
Owners of these breeds should be vigilant for the earliest signs of discomfort in their dog to get the eyes checked. Early medical treatment stands a better chance of success than much later intervention.
Other problems such as eyes popping out of sockets are linked to face shape. Flat-faced breeds such as pugs and pekes are at greatest risk. To avoid problems, the owner should avoid scruffing their dog (which pulls back the eyelids) and use a harness rather than a neck collar.
Owners should be vigilant for signs of eye discomfort, such as blinking and squinting, closing the eye, rubbing, or an ocular discharge, and seek veterinary attention. Prompt treatment of ulcers on the cornea (surface of the eye) can stop them from perforating which could result in the loss of an eye.
Enucleation Questions and Advice from Veterinary Professionals

Our 9.5 year old dog had his eye removed two weeks ago due to glaucoma. His other eye was cloudy but he could still see to go outside, eat treats,etc. Now it is apparent that he has gone blind in the other eye. He is running into things and seems confused. Could a complication of the surgery have caused this or is it more than likely just weird timing?

my dog was attacked by another dog last year, slowly his eye seems like it’s shrinking, and his eyelid is rolling back. i have to clean his eye about once a week because it gets super gross and crusty and slimy very quickly. he itches the eye a lot and won’t let me go near it. should i consider enucleation as an option or should i not be too worried

My almost 13 yr old Papillon had lens luxation surgery in December of 2016. Brought her to vet ophthalmologist today and pressure was very high. They are suggesting either injection or Intrascleral Prosthesis. I asked about removal of the eye completely. They are also quoting $1,200 for injection, $2,400 for removal and $2600 for Intrascleral Prosthesis. Worried cause of her age and the cost is so expensive.

More worried about the surgery because of her age. Her pressure was 30 in her eye. Do you think with meds it can be controlled?

It's got a red ish tinge to it. Doesn't look like puss. Looks like it would be clear if it weren't for the reddish tint. It was fine until we woke up. I read online blood pockets form & if she disturbed it, it could seep out? Some dog's have drainage some don't.

How old does a puppy/ dog need to be in order to have a safe enucleation surgery? I had found homes for these puppies at 8 weeks of age. The family who took in this puppy called me a week or so later and stated the puppy was ill and had gotten a wound on his eye. I took him back and took him to the vet VCA where they recommended and scheduled an Enucleation. Upon further research i was advised that the puppy was too young for this type of surgery. I just want whats best for the puppy and to choose the safest path for him. Is 9/10weeks too young for this procedure ?

It is always beneficial to perform surgery on a dog when they are older (two or three months); but sometimes due to the severity of an injury and the pain, discomfort or possible complications require surgery to be performed at a younger age. I haven’t examined Gumby, but when a Veterinarian recommends surgery, they weigh the risk vs reward etc… If you have concerns, get a second opinion (by a Veterinarian that can examine the eye).

What are the pros and cons of getting the prosthesis eye rather than just stitching the eye closed after Enucleation? Our vet just recommended getting the surgery after they did another review of his eye yesterday. He had a partially detached retina from birth and it has now fully detached. He was first diagnosed two years ago and we have been using a steroid drop to help with the inflammation and it has worked great until a few months ago. They recommended removal because the eye is going to continue to build pressure (I believe) and could be causing him pain and discomfort.

Hi, Christie is a 13 years old miniature Schnauzer, she lost her eye 2 weeks ago because of a weird fight with another dog. The vet removed the stitches 6 days ago and everything seem fine except that she has like a brown crust in the corner of the eye (where the eye used to be). Is this normal?

My dog had an enucleation done last week, now she has some black scab looking substance around a few of the stitchings, there is some discharge but its a very light green (kind of like a booger). She doesn't seem to be in pain and we have finished with all of her antibiotics, her stitches are due to be removed 4 days from now.

We have a puppy, 9 weeks old, that has experienced a corneal perforation where the iris has adhered to the cornea. He is blind in his right eye as a result. He has a scar that has formed over his cornea. Will he be in pain, and should we consider enucleation or leave the bad eye alone?

Hi, my yorkie's eye popped out of his socket over a month ago. We took him to the vet and they told us it was because of infection in his mouth. He needed the eye and all his back teeth removed. Well we couldn't afford that whole surgery so we just got him on antibiotics for 10 days which got rid of the infection in his teeth. He's back to normal if not a better version of himself than before. He's very happy and does not seem in pain. But now I'm not sure what to do about his eye. Will it fall off or close up on its own eventually?? It's completely blind now for sure. He seems to have adjusted to that pretty easy. It's shriveled up now. But when I move it I can see behind it that it is not closed up. If anything surgery may be the only option but till then I'd like to just know if what the eye will do on its own?

My 13, almost 14 year old peke had his right eye removed today. He's already blind in his left and he wasn't seeing much from his right, aside from shadows in bright surroundings. I'm worried about the recovery and how he will handle this once he's home. So lost dogs adjust well?

Generally dogs adjust well to blindness and in many cases dogs will go blind slowly naturally so compensate well overtime; putting Milhouse in familiar surroundings will most likely give him more confidence but he will have a reduced level of activity. Finding his food and water bowl should not be a big task as he will smell his way there and as long as you don’t move them. Regards Dr Callum Turner DVM
My 13yr old shihtzu had her op yesterday for enucleation of her left eye,she has been blind for 7 yr,cause unknown,we have been up most of the night with her crying,we had fought a 4yr battle with dry eye,ulcers and our vet decided that removal of her eye was best option for a pain free life,an operation at 13yrs was a hard decision but a life filled with pain was unthinkable.

My dog had a an enucleation due to a cancerous mass behind his eye. How long after enucleation does it take for the wound to heal? I worry my dog may scratch and the incision will open. It's been almost 3 weeks post op.

One of the possible side effects of the use of hemp oil is lethargy; try giving a low amount or stop using it all together to see if there is an increase in activity. Otherwise speak with your Veterinarian. Regards Dr Callum Turner DVM

My 4 month old mastiff puppy had an enuleation yesterday. I was informed the bone behind the eye is missing. Will there be any additional problems or causes for concern since she is missing that bone? She also has a cleft lip... I don't even understand how that can happen?

My dog has advanced glaucoma in her right eye (not sure if primary) & I’m leaning towards this eye removal surgery. She’s 10 years old pit mix. She’s been taking meds & eye drops for about 2 months now. Her ophthalmologist is charging 1900 for eye removal surgery. Can you recommend a good ophthalmologist in Los Angeles area that is more reasonably priced? I’m in north Hollywood. Thank you !!!

Our chihuahua just had his eye out. He had glaucoma for a couple years, he's only 3 years old. His headaches were bad!! We didn't realize how bad until after his eye was removed. He was like a new puppy! Running and playing! We regretted not doing it sooner because it was the right decision. It cost us $1800, a lot of money but it was worth it to see his quality of life now!!
