What does posterior synechiae mean?
adhesion
posterior synechia – adhesion between the iris and the lens. synechia – adhesions between the iris and the lens or cornea resulting from trauma or eye surgery or as a complication of glaucoma or cataract; can lead to blindness.
What does synechiae mean?
Medical Definition of synechia : an adhesion of parts and especially one involving the iris of the eye: as. a : adhesion of the iris to the cornea. — called also anterior synechia. b : adhesion of the iris to the crystalline lens.
Do you have to break posterior synechiae?
Posterior synechiae can put patients at risk for intraocular hypertension and glaucoma, so it’s best to be aggressive and break synechiae as soon as they form. If not treated quickly and appropriately, a firm scar between the iris and lens will form, making it very difficult to break.
How do you break posterior synechiae?
In this case, a sympathomimetic drug, such as phenylephrine 10%, should be administered topically in your office at follow-up. This combination of steroid, cycloplegic and sympathomimetic typically breaks most cases of posterior synechiae.
What causes posterior synechiae?
Posterior synechiae occur when fibrinous adhesions form between the lens and iris, with fibrovascular organization occurring later (see Figure 11-24). Formation of synechiae is more likely when aqueous protein content is high.
How do you identify 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.
How do you get synechiae?
It is sometimes visible on careful examination but usually more easily through an ophthalmoscope or slit-lamp. Anterior synechia causes closed angle glaucoma, which means that the iris closes the drainage way of aqueous humour which in turn raises the intraocular pressure.
Does 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.
What is a sneaky eye?
Glaucoma can go undiagnosed for years unless you have a comprehensive eye exam. The vision loss that occurs as a result of glaucoma is irreversible. This is why glaucoma may be referred to as the sneaky eye disease.
What causes synechiae in the eye?
Ocular synechia is an eye condition where the iris adheres to either the cornea (i.e. anterior synechia) or lens (i.e. posterior synechia). Synechiae can be caused by ocular trauma, iritis or iridocyclitis and may lead to certain types of glaucoma.
Can you dilate someone with 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.
What causes anterior synechiae?
Peripheral anterior synechiae result from prolonged appositional contact between the iris and trabecular meshwork (as in primary angle-closure glaucoma) or from anterior chamber inflammation or neovascularization (secondary angle-closure glaucoma).
