We reviewed the records of 35 patients (35 eyes) treated with Nd:YAG cyclophotocoagulation for uncontrolled glaucoma and followed for 6 to 36 months or until treatment was declared a failure (loss of light perception, or intraocular pressure (IOP) > 21 mm Hg). The mean pretreatment intraocular pressure was 37.9 mm Hg (range, 20 to 61 mm Hg). The total energy in the initial treatment session ranged from 50.4 to 372.4 J (191.7 ± 66.3 J). After the treatment, the mean IOP was 21.2 mm Hg (range, 0 to 53 mm Hg). The Kaplan Meier survival analysis demonstrated that failures occurred throughout the follow-up period and that the majority of patients required further intervention or lost all vision if followed long enough. Visual outcome was not correlated with energy used. Eleven eyes (31%) lost two or more lines of acuity or lost all light perception. These findings suggest that Nd:YAG cyclophotocoagulation may control IOP but cannot always save vision.
