Adhesions of the Iris of the Eye in Cats
Synechiae are adhesions between the iris and other structures in the eye. They are the result of inflammation in the iris and are particularly common with anterior uveitis (inflammation of the dark tissues of the eye) and trauma to the eye. Synechiae can occur in both dogs and cats.
Symptoms and Types
Synechiae may be anterior or posterior.
Symptoms seen with synechiae include:
Diagnosis is based on an ophthalmic examination, which involves examining the structures of the eye. In addition, dyes may be used on the cornea to detect corneal injuries. Tonometry may be performed to measure the intraocular pressure (the pressure within the eyeball.)
In many cases, no treatment is necessary. If an underlying cause is diagnosed, it should be treated appropriately. In cases where glaucoma is present, laser surgery to repair the synechiae may be attempted.
