目的：比较维吾尔族假性剥脱综合征(PEX)患者、剥脱性青光眼(PEXG)患者视网膜神经纤维层(RNFL)厚度，为早期诊断剥脱性青光眼提供理论依据。

方法：回顾性病例对照研究。选取2018-04/ 2020-06在我院就诊治疗的维吾尔族假性剥脱综合征患者70例70 眼，剥脱性青光眼患者 80例80 眼，按照视野缺损分期分为早中期剥脱性青光眼患者56眼、晚期剥脱性青光眼患者24眼，选取同期本院收治的维吾尔族年龄相关性白内障病例60例60 眼作为对照组。比较四组患者视盘不同位置RNFL厚度。

结果：对照组、假性剥脱综合征组及剥脱性青光眼组患者视野缺损(MD)逐渐加重且剥脱性青光眼组患者MD显著高于假性剥脱综合征组(P<0.01)； 假性剥脱综合征组、早中期剥脱性青光眼组及晚期剥脱性青光眼组视盘不同位置RNFL厚度较对照组均变薄(均P<0.01)； 假性剥脱综合征组患者视盘平均RNFL、下方、上方RNFL厚度均低于对照组(均P<0.01))； 晚期剥脱性青光眼组患者视盘各个位置RNFL厚度明显低于早中期剥脱性青光眼患者(均P<0.01)。

结论：维吾尔族假性剥脱综合征患者早期RNFL厚度较未患有剥脱综合征人群开始变薄，早期对于假性剥脱综合征患者RNFL进行检测有助于剥脱性青光眼疾病诊断并进行治疗。

METHODS: A retrospective case-control study was conducted. A total of 70 cases(70 eyes)of Uyghur PEX patients, 80 cases(80 eyes)of PEXG patients, and 60 cases(60 eyes)of age-related cataract patients who were admitted to our hospital from April 2018 to June 2020 were selected as the PEX group, PEXG group, and CON group, respectively. The PEXG group was further divided into mild-to-moderate stage(56 eyes)and severe stage(24 eyes)based on the stage of visual field defect, and the RNFL thickness at different locations of the optic disc was analyzed.

RESULTS: The mean defect(MD)gradually increased in the CON group, PEX group, and PEXG group, and it was significantly higher in PEXG group than that in the PEX group(P<0.01). The RNFL thickness at different locations of the optic disc in the PEX group, mild-to-moderate stage PEXG group, and severe-stage PEXG group was thinner than that in the CON group(all P<0.01). The mean RNFL thickness, as well as the RNFL thickness below and above the optic disc, were lower in the PEX group than in the CON group(all P<0.01). The RNFL thickness at all locations of the optic disc in the severe-stage PEXG group was significantly lower than that in the mild-to-moderate stage PEXG group(all P<0.01).

CONCLUSION: The RNFL thickness in Uyghur patients with PEX begins to be thinner than those without pseudoexfoliation syndrome, and early detection of RNFL thickness in PEX patients is helpful for the diagnosis and early treatment of PEXG.
