Ocular synechia is an
slit-lamp
.
Anterior synechia causes
closed angle glaucoma, which means that the iris closes the drainage way of aqueous humour which in turn raises the intraocular pressure
. Posterior synechia also cause glaucoma, but with a different mechanism. In posterior synechia, the iris adheres to the lens, blocking the flow of aqueous humor from the posterior chamber to the anterior chamber. This blocked drainage raises the intraocular pressure.
Management
Dilation of the pupil
in an eye with synechia can cause the pupil to take an irregular, non-circular shape (dyscoria) as shown in the photograph. If the pupil can be fully dilated during the treatment of iritis, the prognosis for recovery from synechia is good. This is a treatable status.
To subdue inflammation, topical corticosteroids can be used. A prostaglandin analogue, such as travoprost, may be used if the intra-ocular pressure is elevated.
