特发性黄斑裂孔的视功能

随着玻璃体手术的飞速发展，特发性黄斑裂孔日益受到重视。另外，以往临床上一直作为评价术后疗效主要指标的裸眼及最佳矫正视力，已很难涵盖视觉质量的全部内容。本文介绍对比敏感度、视野、多焦点视网膜电图、立体视功能等现代视功能检查及其在特发性黄斑裂孔中的应用和临床意义，以及手术对其视功能的影响。这些检查不仅对特发性黄斑裂孔的早期诊断、手术适应证把握及术后视觉质量的评价有重要指导意义，而且有助于客观分析术后患者主观视觉质量差的原因并加以处理。熟悉视功能评价的内容和意义，有助于提高此类黄斑裂孔的手术水平，使患者获得更好的术后视觉质量。

Visual function of the idiopathic macular hole

The idiopathic macular hole(IMH)is research priority associated with the regenerate quickly of vitrectomy. The unaided visual acuity and the best corrected visual acuity is partial for the visual acuity of the patient with IMH.The mechanism and clinical significance of modern visual function measurements associated with IMH, including contrast sensitivity, visual field, multifocal electroretinogram, and stereoscopic vision, have been introduced. These measurements could be of great value in early diagnosis of IMH, assessment of surgical indication and evaluation of visual performance after vitrectomy. They would also be helpful to the analysis of postoperative impaired visual function and its management. Having an adequate understanding of the contents and significance of visual function is helpful to the improvement of IMH surgery techniques and postoperative visual acuity.
