Does posterior synechiae affect vision?
Patients presenting with synechiae typically have an underlying inflammatory disease process such as uveitis and will present with related symptoms, such as redness, photophobia, and/or decreased vision.
How do you manage posterior synechiae?
When fibrotic membranes form posterior synechiae, the action of the radial muscle may be insufficient to break the adhesion. In this case, a sympathomimetic drug, such as phenylephrine 10%, should be administered topically in your office at follow-up.
How common is posterior synechiae?
Posterior synechiae are the most common ocular complications in chronic or recurrent anterior uveitis, occurring in 13–91% of affected eyes.

Can you dilate posterior synechiae?
Posterior synechiae are at the pupil margin where the iris is adherent to the anterior lens capsule, which prevents dilation and makes cataract surgery more challenging. Cataract surgery is a good time to manage these synechiae and help restore ocular anatomy and function.
