synechia

Adhesion of parts of the body. In the eye it refers to the iris. Note: also spelt synechiae.
annular synechia Adhesion of the entire pupillary margin of the iris to the capsule of the crystalline lens. Syn. ring synechia. See iris bombé; pupillary block.
anterior synechia Adhesion of the iris to the cornea. It may give rise to angle-closure glaucoma. Syn. goniosynechia (if at the AC angle). See inflammatory glaucoma; indentation gonioscopy; prolapse of the iris; Peter's anomaly; Rieger's syndrome.
posterior synechia Adhesion of the iris to the capsule of the crystalline lens. See iris bombé; iritis; uveitis.
ring synechia See annular synechia.

Healing in the vestibular region is usually by secondary intention due to the limited amount of vestibular skin; also, the nasal mucosa has an inherent characteristic of developing synechia, because whenever the nasal mucosa is breached, fibroblast activity attempts to heal the breach and if two mucosal surfaces are in contact, a synechia between the two surfaces develops.
