synechia

[sinek′ē·ə] pl. synechiae
Etymology: Gk, continuity
an adhesion, especially of the iris to the cornea or lens of the eye. It may develop from glaucoma, cataracts, uveitis, or keratitis or as a complication of surgery or trauma to the eye. Synechiae may prevent or impede flow of aqueous fluid between the anterior and posterior chambers of the eye, resulting in angle closure glaucoma.

synechia

An adhesion, usually of the anterior pole of the eye, which may be anterior–iris to cornea, or posterior–iris to lens capsule

sy·nech·i·a

, pl. synechiae (si-nek'ē-ă, -ē)
Any adhesion; specifically, adhesion of an inflamed iris to the cornea (anterior synechia) or lens (posterior synechia).
[G. synecheia, continuity, fr. syn, together, + echō, to have, hold]

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.

The closed system of the procedure reduces complications such as intraoperative expulsive hemorrhage, anterior synechia, cataract, and angle narrowing.
But we found that packing makes the nasal mucosa raw and actually more susceptible to synechia formation.
Other ocular associations are acute and/or chronic glaucoma, cataract and synechia.
Case Species History 1 EASO 6-y-old captive owl found as a nestling with traumatic injury to the right eye, which resulted in a mature cataract and a posterior synechia.
Another example is unilateral glaucoma from previous trauma, perhaps from a long time ago, which resulted in secondary glaucoma from angle recession or peripheral anterior synechia.
Postoperative complications of turbinate resection include bleeding, crusting, synechia formation, frontal duct stenosis, anosmia, airflow changes, osteitis, cerebrospinal fluid leaks, atrophic rhinitis, and recurrence of hypertrophy.
Dipak Ranjan Naik et al (10) had 3 cases of synechia formation and two had granulations in the operated area which were successfully treated endoscopically as a office procedure.
Topical corticosteroids and mydriatic agents can be administered as first-line treatment for patients with mild anterior uveitis diagnosed prior to the development of ocular complications (early band keratopathy, posterior synechia, cataract, macular edema).
4) Intraocular inflammation manifests itself as increased cells and flare, inflammatory precipitates on the IOL and the endothelium, formation of synechia, and inflammatory cyclitic membranes.
Many strategies have been proposed to prevent lateralization, including turbinate resection, formation of controlled synechia (Bolgerization), and placement of dissolvable packing, a turbinate glove, or middle meatal spacers.
1) However, nasal packing has some inherent disadvantages, such as causing pain, bleeding during pack removal, nasal mucosal damage, septal perforation, nasal synechia, sleep respiratory disturbance, decreased oxygen saturation during sleep, eustachian tube dysfunction and toxic shock syndrome.
