近视眼视网膜神经纤维层厚度与中央角膜厚度相关性研究

Objective To explore the relationship between retinal nerve fiber layer (RNFL) thickness and central corneal thickness (CCT) in myopia eyes.Methods 91 cases (91eyes) were selected from ophthalmological outpatients including 28cases with low myopia ( spherical equivalence [ SE ] ＞ -3.0D), 33 cases with moderate myopia (SE -0.3D ～ -6.0D) and 30 cases with high myopia (SE ＜ -6.0D).All patients received ocular standard examination including intraocular pressure, refraction, slitlamp biomicroscopy and fundus examination.Other ocular diseases except refractive error were excluded.RNFL thickness and CCT were measured by RTVue Fourior-OCT ( Optovue Inc, USA).Refraction diopter was shown as SE.Results The mean RNFL thickness and CCT was ( 108.5 ± 10.1 ) μm, (524.7 ±36.8)μm respectively.These were no significantly different among low, moderate and high myopia ( P ＞ 0.05 ).Temporal RNFL thickness( tl1 ,tu1 ) was significantly positive related with CCT( r =0.281,0.093 of tl1, r= 0.352,0.167 of tu1 respectively in single and multiple variable analysis; P ＜ 0.05 ), nasal ( nl2, nu2)and inferior nasal RNFL thickness( in2,in1 )was significantly positive related with SE( P ＜0.05), inferior temporal RNFL thickness( it2)was significantly negative related with SE( P ＜0.05), and RNFL thickness in other regions were not significant related with CCT and SE ( P ＞ 0.05 ) in single and multiple variable regressive analysis.Conclusion Relationship between RNFL thickness of local paradisc region and CCT in myopia eyes suggested that CCT should be correlative with some sensible structural parameters in glaucomatous neuropathy and might be important in the diagnosis and therapy of glaucoma.     

近视眼视网膜神经纤维层厚度与中央角膜厚度相关性研究

目的 探讨近视眼患者视网膜神经纤维层（RNFL）厚度与中央角膜厚度（CCT）之间的关系.方法 选择91例眼科门诊近视患者（91眼）,其中低度近视（等效球镜度数[SE]＞-3.0D）28例（28眼）,中度近视（SE-0.3D～-6.0D）33例（33眼）,高度近视（SE＜-6.0D）30例（30眼）.均接受包括眼压、验光、裂隙灯、眼底等常规眼部检查,排除除屈光不正以外其他眼部疾病.利用RTVue Fourior OCT（Optovue Inc,USA）测量视盘周围RNFL厚度;利用CAM-L模块测量CCT.结果 近视眼患者RNFL厚度是（108.5±10.1）μm,CCT是（524.7±36.8）μm,在低中高近视组差异均无统计学意义（P＞0.05）.单因素相关及多元线性回归分析发现：颞侧（tl1,tu1）RNFL厚度与CCT呈正相关（tl1单因素及多因素r=0.281,0.093;tu1单因素及多因素r=0.352,0.163;P＜0.05）;鼻侧（nl2,nu2）和下方偏鼻侧（in2,in1）区域RNFL厚度与SE呈正相关（P＜0.05）;下方偏颞侧（it2）RNFL厚度与SE呈负相关（P＜0.05）;其他部位RNFL厚度与CCT、SE无相关（P＞0.05）.结论 近视眼视盘周围局部区域RNFL厚度与CCT存在相关性,表明中央角膜厚度与青光眼视神经病变敏感结构指标具有一定关系,对青光眼诊治具有重要指导意义.

Objective To expore the clinical therapeutic effect of allergic rhinitis using endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray. Methods Sixty allergic rhinitis patients accompanied by deviation of nasal septum, middle turbinate lesions, or/and inferior turbinate lesions, were divided into two groups: observation group with 30 cases, applying endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray (mometasone furoate nasal spray) during perioperative period; control group with 30 patients, only applying steroid nasal spray (mometasone furoate nasal spray). Long-term effect was compared between two groups. Results Sixty cases were followed up for 1 year. The total effective rate was 90.0%(27/30) in observation group,22 cases of significant effect, 36.7% (11/30) in control group,3 cases of significant effect. The total effective rate had significant difference between two groups (P＜0.01). Conclusion Using endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray (mometasone furoate nasal spray) to treat allergic rhinitis has good long-term effect.
