The visual potential of patients with macular diseases involving the fovea has not been adequately documented. We evaluated 55 eyes of patients having discrete macular lesions and related best visual acuity to retinal distance from the fovea. Best visual acuity in the parafoveal area extending from the center of the fovea to a distance of 0.25 disk diameters (DD) away was 20/25 to 20/50; from 0.25 to 0.5 DD, 20/50 to 20/100; from 0.5 to 0.75 DD, 20/100 to 20/200; from 0.75 to 1.0 DD, 20/200 to 20/400; and greater than 1.0 DD, counting fingers. The clinical importance of the findings as they relate to the rationale of laser treatment of macular lesions and to the evaluation of the low-vision is discussed.
涉及中央凹的黄斑疾病患者的视觉潜力尚未得到充分记录。我们评估了55例患有离散性黄斑病变患者的眼睛，并将最佳视力与视网膜距中央凹的距离相关联。从中央凹中心延伸至0.25个视盘直径（DD）距离的旁中央凹区域的最佳视力为20/25至20/50；从0.25至0.5 DD，为20/50至20/100；从0.5至0.75 DD，为20/100至20/200；从0.75至1.0 DD，为20/200至20/400；大于1.0 DD时，为指数视力。讨论了这些发现与黄斑病变激光治疗原理以及低视力评估相关的临床重要性。
