SENSORY AND OCULOMOTOR CONTRIBUTIONS TO OCULAR DISORDER

空间对比敏感度被用来评估血管的损失或变化 患者的总体视觉分辨率具有各种毒性， 炎症性、退行性或先天性视网膜和神经- 视觉系统的眼科疾病。不受标准限制的 使用了强制选择的物理过程，因为 方法可以最大限度地减少误报或错误 在初始测试中诊断为阴性，并将虚假变化降至最低 在重复测试的灵敏度上。对比敏感度测试， 虽然需要更多的耐心测试时间，但继续 优于传统的视力测量，用于检测 早期损失和用于监测视频分辨率的变化 正在接受治疗的病人。以年龄为参照的标准数据 使区分由于以下原因造成的对比敏感度损失成为可能 在正常衰老的基础上预期的眼部疾病。 视网膜图像稳定系统正在建设中。这 系统旨在允许焦点视网膜电图仪和高 小范围、局部区域的分辨率微视野检查 病人的视网膜。

Spatial contrast sensitivity was used to assess losses or changes in overall visual resolution in patients having a variety of toxic, inflammatory, degenerative, or congenital retinal and neuro- ophthalmological disorders of the visual system. A criterion-free forced-choice physchophysical procedure was used, since this method was previously shown to minimize false positive or false negative diagnosis at initial test and to minimize spurious changes in sensitivity with repeated testing. Contrast sensitivity testing, while requiring more patient testing time, continued to be superior to conventional acuity measurements for the detection of early losses and for monitoring changes in visual resolution in patients undergoing treatment. Age-referenced normative data make it possible to distinguish contrast sensitivity loss due to ocular disorder from that expected on the basis of normal aging. A retinal image stabilization system is under construction. This system is intended to permit focal electroretinography and high resolution microperimetry in small, localized regions of a patient's retina.
