What is 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. Uday Devgan.

How does posterior synechiae cause glaucoma?

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.

What causes Posner Schlossman Syndrome?

PSS is believed to be caused by episodic changes in the trabecular meshwork, impeding outflow of aqueous humor, leading to an elevation of IOP (Figure 2) [1]. This process is also accompanied by a mild intraocular inflammation [1].

What is the meaning of synechiae?

The term synechiae comes from the Greek synekhes, which means “hold together.” Synechiae are adhesions that may occur anteriorly in which the iris becomes adherent to the trabecular meshwork in the iridocorneal angle (peripheral anterior synechiae, PAS) or occur posteriorly in which the iris adheres to the anterior …

How is posterior synechiae diagnosed?

Physical examination Posterior synechiae are visualized on standard slit lamp exam. Adhesions noted between posterior portion of iris and anterior capsule of lens. Peripheral anterior synechiae are visualized on gonioscopic examination.

Is Posner Schlossman Syndrome curable?

Posner-Schlossman Syndrome has long thought to be a “benign” disease; most patients are treated for attacks and recover without long-term sequelae. However, a number of patients with repeated attacks, even if treated, may show long term glaucomatous changes in the optic nerve and on visual field testing.

What is masquerade syndrome?

In 1967 the term “masquerade syndrome” was first used by Theodore to describe a case of conjunctival carcinoma that presented clinically as chronic conjunctivitis. Since that time, this term has been utilized to describe a number of ophthalmologic pathologies that mimic intraocular inflammation.

How can you tell the difference between anterior and posterior synechiae?

Posterior synechiae are visualized on standard slit lamp exam. Adhesions noted between posterior portion of iris and anterior capsule of lens. Peripheral anterior synechiae are visualized on gonioscopic examination.
