This study aimed to assess a new nonsurgical treatment for patients who have previously undergone vitrectomy for macular hole with either persistent or reopened holes.
A prospective, noncomparative, consecutive case series.
Fifteen patients (15 eyes) were studied.
Patients were treated by an outpatient method consisting of laser photocoagulation to the foveal pigment epithelium followed by fluid-gas exchange with 20% perfluoropropane gas and prone positioning. Patients without known allergy were treated with two doses of oral Diamox (250 mg) and ciprofloxacin (500 mg).
Visual acuity, intraocular pressure, anatomic status of the macular hole, and cataract were the principal outcome measures studied.
Thirteen of 15 macular holes were closed successfully with 1 or more procedures. All patients with macular hole closure achieved two lines or greater of vision improvement on Snellen testing. Three patients (20%) achieved 20/40 and nine (60%) achieved 20/80 or better. Three patients required more than one procedure. Four patients developed mild transient ocular hypertension.
The combination of office-based outpatient fluid-gas exchange and laser appears to be a safe and cost-effective alternative to repeat surgery in selected patients with persistent or reopened macular holes after vitrectomy, in whom there are no visible epiretinal membranes, or in whom return to the operating room is undesirable for medical or personal reasons.
本研究旨在评估一种针对既往因黄斑裂孔接受玻璃体切除术后出现持续性或复发性裂孔患者的新型非手术治疗方法。
一项前瞻性、非对照、连续病例系列研究。
对15例患者(15只眼)进行了研究。
采用门诊治疗方法,先对黄斑区色素上皮进行激光光凝,然后用20%的全氟丙烷气体进行液气交换并采取俯卧位。对无已知过敏史的患者给予两剂口服醋甲唑胺(250毫克)和环丙沙星(500毫克)。
研究的主要观察指标包括视力、眼压、黄斑裂孔的解剖状态和白内障情况。
15个黄斑裂孔中有13个通过1次或多次手术成功闭合。所有黄斑裂孔闭合的患者在斯内伦视力测试中视力提高了两行或更多。3例患者(20%)达到20/40,9例患者(60%)达到20/80或更好。3例患者需要不止一次手术。4例患者出现轻度短暂性眼压升高。
对于玻璃体切除术后出现持续性或复发性黄斑裂孔、无可见视网膜前膜或因医学或个人原因不宜返回手术室的特定患者,基于门诊的液气交换和激光联合治疗似乎是一种安全且经济有效的重复手术替代方法。
