WebJun 7, 2024 · Destruction of the ciliary body has been used to treat glaucoma since the 1930s[1]. In cyclodestructive procedures, the secretory epithelium of the ciliary epithelium is damaged, which leads to reduced aqueous humor secretion and lower IOP. Because the ciliary epithelium can regenerate, multiple treatments are necessary in some patients to … WebCiliochoroidal effusion leads to relaxation of the ciliary zone and the forward rotation of the ciliary body and, in turn, displaces the iris forward to close the anterior chamber angle. 10,15,16 Finally, the anterior chamber becomes shallower, and acute angle closure may occur.

The intraocular fluid secreted behind the lens (during the posterior displacement of aqueous humor) increases the pressure of the vitreous body, which shifts the iridolenticular diaphragm forward, causing the angle to close and the anterior chamber to shrink. WebThe ciliary body connects on each side of your iris to control the movement of your lens. Your lens and cornea work together to get light to the right spot on your retina.

WebNov 8, 2015 · Cyclodestruction procedures aim to decrease intraocular pressure (IOP) by decreasing production of aqueous humor by the ciliary body (specifically the ciliary processes). There are 3 basic approaches to cyclodestruction (which some prefer to call cycloablation): Cyclocryotherapy. Trans-scleral laser cycloablation. Endoscopic laser … WebCiliary body. The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object. This process is called accommodation.

WebThe ciliary body is a complex, highly specialized tissue that comprises several cell types. The ciliary muscle is situated at the base of the ciliary body and ligaments originating in the ciliary body attach to the lens. Contraction or relaxation of the muscle alters tension on the lens causing it to alter shape and thus shift focus.

WebA number of pathophysiologic mechanisms have been proposed for acute transient myopia, but the findings in this patient support ciliary body swelling as the cause of the changes in the eye. This swelling of the ciliary body results in a forward rotation of the lens-iris diaphragm and the vitreous, which causes both the myopia and the retinal folds. WebUBM can reveal the following changes: anterior rotation of ciliary body, absence of ciliary sulcus, increased ciliary body thickness, fluid in the supraciliary space (supraciliary...

WebUBM showed ciliochoroidal effusion in one half of the circumference and severe edema in three eighths of the ciliary body, which led to an anterior rotation of the ciliary body.
