The Ischemic Optic Neuropathy Decompression Trial (IONDT) is a five year study designed to assess the safety and efficacy of optic nerve sheath decompression surgery (ONDS) for non-arteritic ischemic optic neuropathy, diagnosed within one month of onset of visual symptoms. A standardized, common protocol for treatment and data collection will be used by all centers. This multicenter, randomized clinical trial is designed to compare differences in patients randomized to one of two treatment groups as follows: Treatment Group Treatment Sequences No. of Patients 1. Test Treatment Optic Nerve Sheath 150 Decompression 2. Control Treatment Standard Medical Care 150 (no surgery) The primary hypothesis to be addressed by this trial is whether treatment with ONDS is more effective than standard care in (1) restoring or (2) maintaining central visual acuity in patients with NAION? The primary outcome for this trial (change in visual acuity) will be measured using the New York Lighthouse chart. A gain of three or more lines of visual acuity (doubling of the visual angle) will be considered improvement. Secondary outcomes include change in peripheral visual function (using standard Goldmann perimetry) and incidence of ophthalmic and systemic complications. Patients will be recruited over a two year period and followed for a minimum of one year. Study Centers will include a Chairman's Center, 26 Clinical Centers, and centralized facilities, including a Coordinating Center, a Reading Center, and a Project Office at the National Eye Institute.

缺血性视神经病变减压试验（IONDT）是五年 旨在评估视神经鞘的安全性和功效的研究 非动脉缺血性视神经病变的减压手术（ONDS）， 在视觉症状发作后一个月内诊断。 标准化， 治疗和数据收集的常见协议将由 所有中心。 该多中心随机临床试验旨在 比较随机分配到两个治疗组之一的患者的差异 如下： 治疗组治疗序列的患者编号 1。测试处理视神经鞘150 减压 2。控制治疗标准医疗150 （无手术） 该试验要解决的主要假设是处理是否治疗 在（1）恢复或（2）中，使用OND比标准护理更有效 保持NAION患者的中心视力？ 该试验的主要结果（视力变化）将是 使用纽约灯塔图测量。 增益三个或更多 视力线（视觉角度的两倍）被考虑 改进。 次要结果包括周围视觉的变化 功能（使用标准的Goldmann圆锥体）和眼科发病率 和全身并发症。 患者将在两年内招募 周期，然后至少一年。 学习中心将包括主席中心，26个临床中心和 集中设施，包括协调中心，阅读中心， 以及国家眼科研究所的项目办公室。
