Abstract

Objective: To describe the clinical application and outcome of MicroPulse™ transscleral cyclophotocoagulation (MP-TSCPC) treatment in horses with glaucoma.

Animals studied: Four client-owned horses with primary (n = 2) or secondary (n = 2) glaucoma.

Methods: Horses were treated with MP-TSCPC under standing sedation with a minimum of 30 days of follow-up (range 30-1241 days). Affected eyes were treated with a 31.3% duty cycle and 3000 mW laser power for a total of 180 s. Data collected included signalment, pre- and post-procedure intraocular pressures (IOPs), laser settings, medications, complications, and repeat therapy.

Results: Four horses (5 eyes) received at least one treatment with MP-TSCPC. Mean preoperative IOP was 44 mmHg (range 33-49 mmHg). The immediate mean postoperative IOP was 34 mmHg (4 eyes; range 19-55 mmHg). At 1 week, IOP was 38 mmHg (5 eyes; range 21-80 mmHg), at 2 weeks was 40 mmHg (3 eyes, range 17-80 mmHg), at 1 month was 35 mmHg (5 eyes; range 20-50 mmHg), at 3 months was 18 mmHg (2 eyes; range 14-21 mmHg), at 6 months was 35 mmHg (2 eyes; range 30-39 mmHg), and at >300 days was 24 mmHg (3 eyes; range 18-29 mmHg). Complications included corneal ulceration (n = 1 eye), uncontrolled IOP (n = 3 eyes), and need for repeat treatment (n = 2 eyes).

Conclusions: MP-TSCPC used with the above-described settings was unsuccessful in treating the majority of cases. Future studies should be targeted at primary glaucoma cases and with use of alternative laser settings.

微脉冲™经巩膜环形光凝术在马患者中的应用：四匹马的病例系列。

目的描述微脉冲™经巩膜环形光凝术（MP-TSCPC）在青光眼马匹中的临床应用和治疗效果：方法：马匹在站立镇静状态下接受 MP-TSCPC 治疗，随访至少 30 天（30-1241 天不等）。对患眼用占空比为 31.3%、功率为 3000 mW 的激光进行治疗，共持续 180 秒。收集的数据包括信号、治疗前后的眼压、激光设置、药物、并发症和重复治疗：结果：四匹马（5 只眼）至少接受了一次 MP-TSCPC 治疗。术前平均眼压为 44 毫米汞柱（范围为 33-49 毫米汞柱）。术后即刻的平均眼压为 34 mmHg（4 只眼睛；范围 19-55 mmHg）。术后 1 周，眼压为 38 mmHg（5 只眼睛；范围为 21-80 mmHg）；术后 2 周，眼压为 40 mmHg（3 只眼睛；范围为 17-80 mmHg）；术后 1 个月，眼压为 35 mmHg（5 只眼睛；范围为 20-50 mmHg）；术后 3 个月，眼压为 18 mmHg（2 只眼睛；范围为 14-21 mmHg）；术后 6 个月，眼压为 35 mmHg（2 只眼睛；范围为 30-39 mmHg）；术后超过 300 天，眼压为 24 mmHg（3 只眼睛；范围为 18-29 mmHg）。并发症包括角膜溃疡（1 眼）、眼压失控（3 眼）和需要重复治疗（2 眼）：结论：在上述条件下使用 MP-TSCPC 治疗大多数病例并不成功。今后的研究应针对原发性青光眼病例，并使用其他激光设置。
