On the relevance of the long-time follow-up of the cyclocryotherapy
Herde JOphthalmologe 1999; 96: 600-604
Despite of the availability of cyclocryodestructive laser therapy, there still appears to be an indication for cyclocryotherapy in different kinds of glaucoma. PURPOSE: Cyclocryotherapy very often appears to be the operation of choice in cases of progressive functional visual loss if a patient is not sufficiently helped with the maximum tolerated medical therapy. The authors investigated long-term IOP effects and possible complications in their group of patients undergoing cyclocryotherapy. PATIENTS: Cyclocryotherapy was performed on 109 eyes of 97 patients from 1988 to 1994. Cyclocryotherapy was performed as follows: 67 of 109 eyes were controlled for IOP for an average of ten months (3-41 months). The authors applied cryotherapy six times 3-4 mm behind the limbus for an average duration of 50-60 seconds over half of the circumference. RESULTS: The authors achieved satisfactory IOP control (IOP ≤22 mmHg) in 40 eyes, however, with 30 additional operations. One eye developed phthisis bulbi, and three others became blind because of complications in neovascular glaucomas. Neovascular glaucoma cases responded the least. CONCLUSIONS: Cyclocryotherapy produced a statistically significant IOP reduction in eyes with primary open-angle glaucoma or secondary glaucoma. Close long-term follow-up appears advisable in order to check the eyes for possible increase in IOP or complications of surgery.LA: German
