What does the term "synechia" refer to?

The term "synechia" refers specifically to the adhesion of the iris to either the lens or the cornea. This condition can occur when inflammation in the eye leads to the formation of scar tissue, causing the iris to stick to adjacent structures. Synechia can have significant implications for ocular health, potentially leading to complications such as increased intraocular pressure and secondary glaucoma.

Understanding synechia is crucial in veterinary ophthalmology, as it can affect both vision and overall eye function in affected animals. Timely diagnosis and treatment are essential to prevent further complications associated with these adhesions. The other options mention conditions that are related to ocular health but do not encapsulate the specific definition of synechia.
