Micropulse Transscleral Diode Laser Cyclophotocoagulation in Refractory Glaucoma
摘要： Purpose: To assess the short-term ef?cacy and safety of micropulse transscleral diode laser cyclophotocoagulation (MP-TSCPC) in the management of refractory glaucoma and to compare outcomes based on prior glaucoma surgeries. Design: Retrospective analysis. Participants: Patients with refractory glaucoma who underwent MP-TSCPC at a single institution by 1 of 4 surgeons. Methods: Chart review of cases of MP-TSCPC using the Iridex Cyclo G6 (Mountain View, CA) laser with standard parameters and laser duration at the discretion of each treating physician. Main Outcome Measures: Probability of postoperative success was estimated by the Kaplan-Meier method. Success parameters included intraocular pressure (IOP) 6 to 21 mmHg with or without topical antihypertensive therapy, 20% or more IOP reduction from baseline for any 2 consecutive visits after 3 postoperative months, and no subsequent glaucoma surgery. Results: One hundred sixteen eyes of 116 patients (mean age, 65.8±16.9 years) were included. Baseline IOP was 22.2±7.9 mmHg, and mean postoperative follow-up time was 6.3±3.4 months (range, 3e12 months.) Postoperative IOP at the ?nal follow up was 15.3±6.6 mmHg (P < 0.01), corresponding to a reduction of approximately 6.9 mmHg (31.1%). Most eyes (66.4%) underwent at least 6 months of follow-up. Short-term probability of success was 93.1% at 3 months and 74.3% at 6 months. Eyes that had undergone prior traditional glaucoma surgery (trabeculectomy, tube shunt, excessive pressure-regulating shunt system miniature glaucoma shunt [Alcon, Fort Worth, TX], or a combination thereof) demonstrated a higher probability of success (67.6%) compared with eyes that had not (41.4%; P ? 0.014). The most common complications were decline in best-corrected visual acuity (7.8%) and hypotony (1.7%). Conclusions: Micropulse transscleral diode laser cyclophotocoagulation has a signi?cant short-term ocular hypotensive effect and favorable safety pro?le in eyes with refractory glaucoma. The probability of successful outcome was greater in eyes that had undergone prior traditional glaucoma surgery. Ophthalmology Glaucoma 2019;-:1e11 a 2019 by the American Academy of Ophthalmology

Contact Transscleral Cyclodiode Laser Treatment for Refractory Glaucoma After Penetrating Keratoplasty
摘要： This is a retrospective study with long-term follow-up using transscleral cyclodiode laser photocoagulation (TCP) with low complication rate and good graft survival and intraocular pressure (IOP) control. Selective 180-degree TCP may offer a good IOP control with reduced complication rates.
