PURPOSE: To report treatment outcomes of primary transscleral cyclophotocoagulation (TSCPC) in glaucomatous eyes. DESIGN: Retrospective noncomparative study. PARTICIPANTS: Forty-eight eyes with a diagnosis of glaucoma and no previous incisional ocular surgery. METHODS: Continuous-wave TSCPC was applied to the ciliary body. MAIN OUTCOME MEASURES: The primary outcome measure was surgical success defined as an IOP ≤ 21 mmHg and reduced by 20% or more from baseline, IOP > 5 mmHg, no reoperation for glaucoma, and no loss of light perception vision. Secondary outcome measures included visual acuity (VA) and complications. RESULTS: Glaucoma eyes were stratified into 2 groups: (1) those with pretreatment IOP >21 mmHg (high group) and (2) those with pretreatment IOP ≤ 21 mmHg (low group). Mean ± standard deviation (SD) IOP at baseline was 30.6 ± 6.3 mmHg in the high group and 16.2 ± 2.8 mmHg in the low group. Mean ± SD number of glaucoma medications at baseline was 4.1 ± 0.8 in the high group and 3.6 ± 1.1 in the low group. Based on our success criteria, the cumulative probability of success during the first year of follow-up was 58.3% in the high group and 28.1% in the low group (P = 0.052). Postoperative mean IOP was significantly lower than baseline IOP in the high group at 1-, 3-, 6-, 12-, and 18-month postoperative visits (P < 0.05). No significant change was observed in IOP at follow-up visits after 1 month in the low IOP group. Throughout the first year of follow-up, both groups required fewer glaucoma medications compared with baseline at the 1-, 3-, 6-, and 12-month postoperative visits (P < 0.05). The most frequent cause of postoperative decrease in VA was cataract in 9 eyes. Decrease in vision resulting from glaucoma was observed in 3 eyes. Complications included prolonged inflammation (11 eyes), iris neovascularization (2 eyes), cystoid macular edema (4 eyes), and hyphema (1 eye). No severe or long-term complications were observed. CONCLUSIONS: Continuous-wave TSCPC was effective in lowering IOP in glaucoma patients without prior incisional ocular surgery whose disease was recalcitrant to medical therapy, particularly those with baseline IOP of more than 21 mmHg.
