This review examines the concept of the preferred retinal locus (PRL) in patients with macular diseases. Considering monocular and binocular viewing, we ( a) explain how to identify the PRL and discuss the pitfalls associated with its measurement, ( b) review the current hypotheses for PRL development, ( c) assess whether the PRL is the new reference point of the ocular motor system, and discuss ( d) the functional and ( e) the clinical implications of the PRL. We conclude that the current definition of the PRL is probably incomplete and should incorporate the need to evaluate the PRL in the framework of binocular viewing. We emphasize the need for more research.

什么是首选视网膜位点？

本综述探讨了黄斑疾病患者首选视网膜位点 (PRL) 的概念。考虑单眼和双眼观察，我们 (a) 解释如何识别 PRL 并讨论与其测量相关的陷阱，(b) 回顾当前 PRL 发展的假设，(c) 评估 PRL 是否是 PRL 的新参考点眼运动系统，并讨论 (d) PRL 的功能和 (e) 临床意义。我们的结论是，当前 PRL 的定义可能不完整，应该纳入在双眼观察框架中评估 PRL 的需要。我们强调需要进行更多研究。
