Background: The cyclophotocoagulation (CPC) is a cyclodestructive
procedure and the method of first choice in cases of refractory glaucoma
with the exception of neovascular glaucoma.
Patients and Methods: We report about the results of CPC using
a 810 nm diode laser (4 sec., 1250 - 1750 mW, 15 pulses) on 100 patients
(120 eyes) with a mean age of 55 years. 86 eyes with primary open-angle
glaucoma, 20 eyes with primary angle-closure glaucoma, 8 eyes with secondary
glaucoma, 5 eyes with congenital glaucoma and 1 eye with a pseudoexfoliation
syndrome were enrolled.
Results: The average of preoperative intraocular pressure was 23.1
mm Hg, and 16 mm Hg after 3 months, resulting in a decrease rate of 26
% (7 mm Hg). Furthermore, a reduction of eye-drop applications was achieved
in 50 % of all cases. Despite repeated CPC 5 eyes showed an insufficient
intraocular pressure. Following complications were observed: 11 discrete
pupillary unroundings, 1 strong fibrine reaction, 1 cyclitis with hypotension
and choriodal detachment and 1 cataract, respectively.
Conclusions: CPC is an easy to apply effective method in patients
with therapy-refractory glaucoma with a high decrease rate of intraocular
pressure as well as low rate of complications.
