Symblepharon

Symblepharon is an eye condition in which different parts of the conjunctiva, the tissue lining the eyelids and covering the eye, stick together or adhere to the cornea. This can happen after severe inflammation or infection, especially from feline herpesvirus, and may lead to discomfort, reduced eyelid movement, and vision problems in young kittens.

A large retrospective study of 177 kittens (54 affected eyes) examined how common symblepharon is, the different ways it can present, and how kittens respond to medical or surgical treatment. Researchers found that symblepharon is not a single disease but a collection of related eye conditions, including eyelid deformation, adhesions between conjunctival surfaces, and adhesions involving the third eyelid or cornea.

Outcomes varied depending on the type of symblepharon and the treatment used. Some kittens improved with medical management alone, while others benefited from surgery. Certain forms, such as corneoconjunctival adhesions, were more difficult to treat, though surgery helped reduce corneal opacity in many cases. Most kittens retained vision and eye reflexes even when the condition persisted.

This research helps veterinarians and shelter teams better understand when and how to intervene, offering insights that can improve decision making, treatment planning, and long term care for kittens with this complex eye condition.
