PURPOSE: To evaluate the usefulness of the krypton laser for transscleral contact cyclophotocoagulation in the treatment of posttraumatic glaucoma. PATIENTS AND METHODS: A total of 18 eyes of 18 patients with therapy-resistant post-traumatic glaucoma treated with krypton laser cyclophotocoagulation from 1991 to 1996 were included in this review. The krypton laser was delivered by a fiberoptic probe with simultaneous compression of the sclera. The energy used was 3-5 J per application at the tip of the probe, with an exposure time of ten seconds. The treatment covered 90-360° of the ciliary body with approximately ten applications per quadrant. RESULTS: With one or more cyclophotocoagulation treatment, the intraocular pressure decreased from the baseline mean (± SD) of 32.6 ± 12.8 to 23.6 ± 10.3 mmHg (n = 17) at one month, to 21.8 ± 7.5 mmHg (n = 13) at three months, 22.5 ± 7.6 mmHg (n = 13) at six months, and 19.6 ± 10.5 mmHg (n = 18) at the last control visit (mean, 19.4 months; range, three weeks to 73 months) after cyclophotocoagulation but no other glaucoma procedure. At baseline, 17 (94%) of 18 patients were taking glaucoma medication, as were 15 (83%) of 18 patients at the last control visit. One (6%) case of phthisis occurred. CONCLUSIONS: Krypton laser cyclophotocoagulation is an effective and reasonably well tolerated means of lowering intraocular pressure in post-traumatic glaucoma. Because of the refractory nature of the disease, repeated treatments may be needed.
