Posterior synechiae and anterior synechia may prevent the aqueous fluid from flowing freely through the anterior and posterior chambers of the eye. The blockage caused by anterior and posterior synechia or synechiae results in angle closure glaucoma.
Forms Of Iris Adhesion
- Anterior synechiae: adhesion of the iris to the cornea of the eye
- Posterior synechiae: adhesion of the iris to the lens capsule or vitreous body
- Total synechia: adhesion of the surface of the iris to the eye’s lens
- annular synechia: adhesion of the entire iris rim to the eye lens
Common CausesPosterior synechia or synechiae may be caused as a result of keratitis, uveitis, glaucoma, and cataracts. Anterior synechia and posterior synechia can also be a result of eye trauma or complication during eye surgery.
Treatment And PrognosisMydriatic and cycloplegic agents may be used to prevent posterior synechia and anterior synechiae or by dilating the iris of the eye and keeping the iris away from the lens.
If the pupil of the eye can be dilated fully the prognosis for recovering from synechiae is very positive. Inflammation from synechiae or synechia may be treated with topical corticosteroids.
