摘　　要：原发性开角型青光眼(POAG)是一种常见的致盲性眼病,其发病机制复杂,与OPTN基因发生突变有关。其中与POAG相关的OPTN突变有H26D、E50K、M98K、E103D、691_692insAG、T202R、A336G、A377T、H486R、R545Q等。OPTN基因编码的Optineurin蛋白是重要的自噬受体,参与细胞自噬。研究发现OPTN基因某些突变可通过使视网膜神经节细胞(RGCs)自噬异常引起POAG。本文从OPTN突变与POAG、OPTN与其编码蛋白Optineurin、RGCs自噬与POAG、OPTN突变致RGCs自噬异常的相关基础研究等方面进行综述。Primary open-angle glaucoma(POAG)is a common blinding eye disease,and its pathogenesis is complicated,which is related to OPTN gene mutation.POAG-related OPTN mutations include H26 D,E50 K,M98 K,E103 D,691_692 insAG,T202 R,A336 G,A377 T,H486 R,R545 Q,etc.Optineurin protein encoded by OPTN gene is an important autophagy receptor involved in autophagy.It has been found that some mutations of OPTN gene can cause POAG by abnormal autophagy of retinal ganglion cells(RGCs).In this paper,basic studies on OPTN mutation and POAG,OPTN and its encoding protein Optineurin,RGCs autophagy and POAG,and OPTN mutation induced RGCs autophagy abnormality are reviewed.
