cyclodialysis

 [si″klo-di-al´ĭ-sis]
creation of a communication between the anterior chamber of the eye and the suprachoroidal space, in glaucoma.

cy·clo·di·al·y·sis

(sī'klō-dī-al'i-sis),
Establishment of a communication between the anterior chamber and the suprachoroidal space to reduce intraocular pressure in glaucoma.
[cyclo- + G. dialysis, separation]

cyclodialysis

/cy·clo·di·al·y·sis/ (-di-al´ĭ-sis) creation of a communication between the anterior chamber of the eye and the suprachoroidal space, in glaucoma.

cyclodialysis

[-dī·al′isis]
1 a surgical procedure performed on patients with glaucoma. A pathway is opened between the anterior chamber of the eye and the suprachoroidal space, allowing excess fluid to drain and reducing intraocular pressure.
2 separation of the ciliary body from the sclera, usually as a result of trauma, causing decreased intraocular pressure, or hypotony.

cy·clo·di·al·y·sis

(sī'klō-dī-al'i-sis)
Establishment of a communication between the anterior chamber and the suprachoroidal space in order to reduce intraocular pressure in glaucoma.
[cyclo- + G. dialysis, separation]

cyclodialysis

Surgical separation of the ciliary body of the eye from the sclera so as to reduce its efficiency in secreting aqueous humour and lower the pressure within the eye in GLAUCOMA.

cyclodialysis 

Disinsertion of the ciliary body from the scleral spur which may produce a cyclodialysis cleft resulting in hypotony. It is performed occasionally in the treatment of glaucoma to reduce the intraocular pressure, as it forms a communication between the anterior chamber and the suprachoroidal space. It may also occur as a result of trauma or intraocular surgery (e.g. trabeculectomy). See recession angle; uveoscleral pathway.

cyclodialysis

creation of a communication between the anterior chamber of the eye and the suprachoroidal space, to allow alternative route of filtration for aqueous humor in glaucoma.

An alternative explanation is the closing of a tear in the trabecular meshwork or a traumatic cyclodialysis cleft.
Besides angle recession and peripheral anterior synechia, other findings on gonioscopy included iridodialysis (2 patients), cyclodialysis (1 patient), blood clots in the angle, heavy pigmentation of trabecular meshwork, convex iris and haptic of PCIOL lodged in the angle.
