How is the third eyelid removed from dogs? - briefly
The third eyelid in dogs, also known as the nictitating membrane, can be surgically removed through a procedure called cherry eye surgery. This involves making a small incision to expose and remove the gland, then closing the wound with sutures.
How is the third eyelid removed from dogs? - in detail
The removal of the third eyelid (nictitating membrane) from a dog, also known as a cherry eye surgery, is a common veterinary procedure performed to address prolapse or eversion of this structure. Here’s a detailed overview of how this surgical process typically unfolds:
The third eyelid serves a protective function in dogs, secreting tears and providing additional coverage for the eye. However, when it becomes prolapsed, it can cause discomfort and potential complications. The decision to remove the third eyelid is usually made after other treatment options, such as medication or manual replacement, have been attempted without success.
Before the surgery, a thorough examination and diagnostic tests are conducted to ensure that the dog is healthy enough for the procedure. Pre-anesthetic blood work and an assessment of the eye’s health are typically performed. The veterinarian will also discuss post-operative care with the owner.
On the day of the surgery, the dog is placed under general anesthesia to ensure comfort and immobility during the procedure. Once the anesthesia has taken effect, the area around the eye is carefully cleaned and prepped using a sterile solution. An eyelid speculum may be used to keep the eye open and provide better access to the third eyelid.
The veterinarian will then use fine surgical instruments to carefully dissect the tissue surrounding the third eyelid, taking care not to damage any blood vessels or nerves in the area. The prolapsed gland is gently retracted back into its normal position if possible. If the gland cannot be replaced or if it has become severely damaged, it may need to be removed completely.
In cases where the third eyelid needs to be removed, the surgeon will carefully excise the tissue using precise cuts. The incisions are then closed with fine sutures to ensure proper healing and minimize scarring. In some instances, a portion of the gland may be left in place to maintain tear production, but this depends on the severity of the prolapse and the overall health of the gland.
After the surgery, the dog is monitored closely as it recovers from anesthesia. Once awake, the veterinarian will provide instructions for post-operative care, which may include administering pain medication, antibiotics, and eye drops to prevent infection and promote healing. The owner will also be advised on how to monitor the dog’s recovery and when to return for follow-up appointments.
In summary, the removal of the third eyelid in dogs involves careful pre-operative planning, meticulous surgical technique, and diligent post-operative care to ensure the best possible outcome for the animal.
