摘　　要：目的探讨原发性开角型青光眼(primary open angle glaucoma,POAG)患者视网膜神经纤维层(retinal nerve fiber layer,RNFL)厚度与视野缺损的相关性。方法选取2013年4月至2014年5月我院收治的30例(30眼)POAG患者作为观察组,另选取同期于我院体检的30名健康者作为对照组,检测两组受试者的RNFL厚度及视野缺损情况。结果观察组上方、下方、颞侧、鼻侧四个象限的RNFL厚度分别为(92.53±10.72)μm、(91.48±11.45)μm、(74.68±8.33)μm、(71.45±9.15)μm,对照组分别为(141.67±19.45)μm、(137.61±18.46)μm、(94.55±11.64)μm、(90.49±10.48)μm,差异均有统计学意义(均为P<0.05);观察组上方、下方、颞侧、鼻侧四个象限的视野缺损值分别为(6.49±0.84)dB、(5.91±0.69)dB、(8.42±0.95)dB、(7.29±0.94)dB。相关性分析显示,观察组RNFL厚度与各相应视野内的视野缺损呈负相关,回归系数b的差异均有统计学意义(均为P<0.05)。结论 POAG患者存在RNFL损伤及视野缺损,且二者具有负相关性,能够准确判断病情。Objective To study the correlation between retinal nerve fiber layer （RNFL） thickness and visual field defect in primary open-angle glaucoma（POAG） pa- tients. Methods Thirty patients（30 eyes） with POAG in our hospital from April 2013 to May 2014 were enrolled in observation group, and 30 healthy subjects received physi- cal examination over the same period were enrolled in control group. Then RNFL thick- ness, and visual field defect were detected. Results RNFL thickness of upper visual field, lower visual field, temporal visual field, nasal visual field in observation group were （92.53 ± 10.72） μm,（91.48 ± 11.45）μm, （74.68 ±8.33） μm and （71.45 ±9. 15） ixm,respectively,which in control group were （ 141.67 ± 19.45） μm, （ 137.61 ± 18.46） μm, （ 94.55 ± 11.64 ） txm and （ 90.49 ±10.48 ） μm, respectively, there were statistical difference between two groups（ all P 〈 0.05 ）. The visual field defect value of upper visu- al field, lower visual field, temporal visual field, nasal visual field in observation group were （ 6.49 ± 0.84 ） dB, （ 5.91 ± 0.69 ） dB, （ 8.42 ± 0.95 ） dB and （ 7.29 ±0.94 ） dB. RNFL thickness was negatively correlated with visual field defect in corresponding fields in observation group （ all P 〈 0.05 ）. Conclusion POAG patients exist RNFL damage and visual field defect, and RNFL thickness is negativeky correlation with visual field defect, they can accurately judge the disease condition.
