Popis: | Cyclodestruction therapy decreases intraocular pressure (IOP) by destroying ciliary bodies, thereby reducing aqueous humor production. Cyclocryotherapy was initially introduced by Bietti [1] in 1950 to reduce IOP. However, it was not a popular therapy until the late 1960s, when de Roetth [2] reported a success rate of 73% with cyclocryotherapy in 165 adult patients with uncontrolled IOP. Currently, this procedure is mainly reserved for end-stage or very severe cases of refractory glaucoma. Also, because of the variable success rates reported in adults (34% to 92%), and the significant postoperative pain and complications associated with cyclocryotherapy including phthisis and retinal detachment, transscleral neodymium: YAG (Nd: YAG) and diode lasers are replacing cyclocryotherapy as the preferred form of cyclodestruction in advanced patients [3,4,5]. When undergoing transscleral treatments to the ciliary region, the long posterior ciliary arteries and nerves lying in the suprachoroidal space and the conducting sensory impulses from the cornea are susceptible to damage. Therefore, treatment to the 3-o'clock and 9-o'clock positions has always been avoided to prevent damage to the long posterior ciliary arteries and nerves, which can lead to development of phthisis. However, Streiff and Stucchi [6] described a procedure to destroy long posterior ciliary vessels in order to minimize increases in IOP, a method that they termed cycloanemization. They reported an overall success rate of 57% to 64% in different types of glaucoma. The purpose of this study was to report the long-term follow-up results after cyclocryotherapy was performed on the quadrants and the 3-o'clock and 9-o'clock positions of blind refractory glaucoma patients'eyes. |
