Diagnostic Consistency and Relation Between Optical Coherence Tomography and Standard Automated Perimetry in Primary Open-Angle Glaucoma

Purpose: To assess diagnostic consistency and relation between spectral-domain optical coherence tomography (SD-OCT) and standard automated perimetry (SAP) in patients with primary open-angle glaucoma (POAG). Methods: This retrospective study comprised 51 eyes of 51 patients with a confirmed diagnosis of POAG. The qualitative and quantitative SD-OCT parameters (retinal nerve fiber layer thicknesses [RNFL; average, superior, inferior, nasal and temporal], RNFL symmetry, rim area, disc area, average and vertical cup/disc [C/D] ratio and cup volume) were compared with parameters of SAP (mean deviation, pattern standard deviation, visual field index, and glaucoma hemifield test reports). Results: Fifty-one eyes of 51 patients with POAG were recruited. Twenty-nine eyes (56.9%) had consistent RNFL and visual field (VF) damage. However, nine patients (17.6%) showed isolated RNFL damage on SD-OCT and 13 patients (25.5%) had abnormal VF test with normal RNFL. In patients with VF defect, age, average C/D ratio, vertical C/D ratio, and cup volume were significantly higher and rim area was lower when compared to those of the patients with normal VF. In addition to these parameters, worsening in average, superior, inferior, and temporal RNFL thicknesses and RNFL symmetry was significantly associated with consistent SD-OCT and SAP outcomes. Conclusions: In routine practice, patients with POAG can be manifested with inconsistent reports between SD-OCT and SAP. An older age, higher C/D ratio, larger cup volume, and lower rim area on SD-OCT appears to be associated with detectable VF damage. Moreover, additional worsening in RNFL parameters might reinforce diagnostic consistency between SD-OCT and SAP.     

青光眼结构与功能损害的关系

青光眼视网膜神经节细胞及其轴突损害导致视网膜神经纤维层(RNFL)进行性萎缩,伴随出现视功能的损害.青光眼视野缺损典型表现为神经纤维束性视野缺损.一般认为先出现RNFL损害,再出现视野缺损,且视野缺损和RNFL损害的位置具有对应性.与HRT、GDx相比,OCT测量的RNFL厚度能更好地用于评价青光眼损害的结构与功能关系.青光眼结构损害和功能性改变之间的对应关系,对于青光眼的诊断、分期和视功能评估起着重要作用.本文就青光眼结构与功能损害关系的研究进展做一综述.     

视网膜神经纤维层定量测定在青光眼方面的应用

青光眼的主要病理过程是视网膜节细胞轴突（即视神经纤维）的丢失，故测量视网膜神经纤维层（ｒｅｔｉｎａｌｎｅｒｖｅｆｉｂｅｒｌａｙｅｒ，ＲＮＦＬ）来确定轴突丢失的程度在青光眼的早期诊断和治疗上具有非常重要的意义。近年来，计算机图像分析技术应用于眼科，它能对ＲＮＦＬ作出客观的量化检测。该文综述有关文献，就ＲＮＦＬ定量测定方法的原理，以及它们在青光眼ＲＮＦＬ损害检测方面的应用情况作一介绍。

目的：：探讨原发性开角型青光眼( primary open angle glaucoma, POAG)早期上下半视盘周围视网膜神经纤维层( retinal nerve fiber layer, RNFL)的变化特征。方法：临床观察研究,研究对象为2012-05/2014-05在我院门诊确诊为原发性开角型青光眼早期患者30例39眼和健康成人20例40眼,使用Humphrey视野计和光学相干断层成像术( optical coherence tomography,OCT)检查,分别记录视野平均缺损( mean defect,MD)、青光眼半视野检测( glaucoma hemifield test, GHT)、眼压、C/D比值及视盘周围FNFL厚度。使用SPSS 18.0统计软件对测量值进行统计分析,计量资料组间比较采用t检验。结果：两组上半视盘各钟点位的RNFL厚度减去下半视盘相对应钟点位的RNFL厚度,两组间比较,仅上鼻-下鼻的差值具有统计学意义(t=2.526,P=0.014),其余上下半视盘相对应钟点位RNFL厚度的差值比较,两组间均无统计学意义(均为P>0.05)。结论：原发性开角型青光眼早期上下半视盘周围RNFL存在不对称性变化,上鼻部位(右眼1：00位,左眼11：00位)的RNFL较下鼻部位(右眼5：00位,左眼7：00位)的RNFL更容易受损变薄。

Effects of Nerve Growth Factor in the Treatment of Non-Arteritic Anterior Ischemic Optic Neuropathy

Objective: To observe the effects of nerve growth factor (NGF) in the treatment of non-arteritic anterior ischemic optic neuropathy (NA-AION). Methods: This was a prospective, randomized, controlled study. Fifty-eight NA-AION patients (58 eyes) admitted to Lianshui County People's Hospital from July 2016 to June 2019 were selected, and then were divided into a control group and an observation group based on the random numerical table method. The control group (29 patients with 29 eyes) were given glucocorticoid hormones, Huoxue Tongluo granules and an anisodine compound. While the observation group (29 patients with 29 eyes), were treated with NGF in addition to the treatment plan previously described. The total effective rate, best corrected visual acuity (BCVA), the 30-degree visual-field examination mean deviation (MD) and the disc retinal nerve fiber layer (RNFL) thickness of the two groups were compared. Data were analyzed by the Fisher's exact test, a t test and a non-parametric test. Results: After treatment, the total effective rate for the observation group was significantly higher than that for the control group (P=0.04),the percentage of BCVA above 0.1 in the observation group was significantly higher than that in the control group (P<0.001), and both the MD and RNFL thickness in the observation group were significantly lower than those in the control group (t=2.59, P=0.01; t=4.86, P<0.001). There were no obvious adverse reactions for either group after treatment. Conclusions: The treatment of NA-AION with NGF can obtain a better effective rate, improve the patient's vision, improve the visual field and reduce RNFL thickness.     

原发性开角型青光眼和闭角型青光眼早期视神经损害特征的比较

目的比较原发性开角型青光眼（POAG）和原发性闭角型青光眼（PACG）的早期视神经损害特征和视野损害特点的差异。设计前瞻性病例系列。研究对象早期POAG患者23例（30眼），早期PACG患者22例（30眼）。方法进行静态视野和偏振激光扫描仪GDx ECC检查。分别比较两组间GDx ECC各个参数和视网膜神经纤维层缺损（RNFLD）类型（弥漫性、局限性）的差异。在组间分别比较视野参数、视野检测光标点对点的光敏度丢失。主要指标GDx ECC参数及其RNFLD类型、视野参数、视网膜光敏度丢失。结果两组中GDx ECCTM参数除了上方均值和对称性以外，其余各个参数在两组间的差异均有统计学意义。弥漫性RNFLD在POAG和PACG中的比例分别为40％和10％（P〈0．05），局限性RNFLD分别为53％和63％。视野指数中PSD和CPSD在两组间差异有统计学意义（P〈0．05）。在视野检测的点对点比较中，早期PACG的局部光敏度丢失在颞上方视野中较早期POAG严重（P〈0．05）。结论早期POAG有较多弥漫性RNFLD，而早期PACG主要表现为局限性RNFLD。早期PACG在颞上方的局部光敏度丢失较早期POAG严重，这与其RNFL缺损特征相一致。POAG和PACG不同的发病机制可能是导致RNFL损害特征和视野损害特点差异的原因。（眼科，2007,16：28-32）

频域OCT检测视野前青光眼黄斑区视网膜神经节细胞复合体厚度的初步研究

Objective To evaluate the diagnostic capabilities of ganglion cell complex (GCC) thickness in preperimetric glaucoma (PPG) with spectral domain optical coherence tomography (SD-OCT). Design Self control study and case control study. Participants Primary open-angle glaucoma (POAG) patients were 20 cases(40 eyes), of which 20 eyes without visual field defects as PPG, and healthy controls were 30 cases(30 eyes). Methods All subjects were underwent macular scanning and peripapillary retinal nerve fiber layer (RNFL) scanning using the RTvue SD-OCT. The area under the receiver operating characteristic curve (AUC) was used to assess the ability to discriminate PPG from normal control. Main Outcome Measures The thickness of GCC and RNFL, and their AUCs. Results Compared with normal eyes, the thickness of average GCC, superior GCC, inferior GCC, average RNFL, superior RNFL, and inferior RNFL in PPG eyes decreased (P<0.001). However, these parameters were thicker than POAG eyes (P≤0.002). The values of GCC-GLV and GCC-FLV increased compared with normal eyes (P<0.001, P=0.021), but decreased compared with POAG eyes (P<0.001). GCC-GLV had highest AUC for detecting PPG (0.983) from normal eyes, followed by average RNFL (0.930). However, the difference between the two parameters was not statistically significant (P>0.05). Conclusions In addition to RNFL, the GCC could be a structural parameter for detecting PPG. (Ophthalmol CHN, 2017, 26: 10-14)

Comparison of the Diagnostic Ability of Retinal Nerve Fiber Layer Thickness Measured using Time Domain and Spectral Domain Optical Coherence Tomography in Primary Open Angle Glaucoma

 Purpose: To evaluate and compare the diagnostic ability of retinal nerve fiber layer (RNFL) thickness measurements using time domain (Stratus) and spectral domain (Cirrus HD) optical coherence tomography (OCT) in preperimetric and early primary open angle glaucoma (POAG). Methods: A total 62 eyes of 62 normal subjects, 47 eyes of 47 early perimetric damage POAG patients and 30 eyes of 30 preperimetric glaucoma patients were chosen in the study. All the subjects underwent peripapillary RNFL thickness measurements using Stratus OCT and Cirrus HD-OCT on the same day by a single trained operator. The RNFL thickness measured by Stratus OCT and Cirrus HD-OCT was statistically compared using paired t-tests. The relationship between RNFL thickness measured by two OCT instruments was evaluated using Pearson’s correlation coefficient. Areas under the receiver operating characteristic curves (AROC) were calculated and compared. Results: RNFL thickness measured using Stratus OCT was generally thicker than that using Cirrus HD-OCT(P＜0.05). A highly significant correlation between the two OCT instruments measurements was found in four quadrants and average RNFL thickness measurements (P＜0.001). The average RNFL thickness of Cirrus HD-OCT had significantly (P = 0.006) higher diagnostic ability (AROC = 0.951) than that of Stratus OCT (AROC = 0.881) in preperimetric glaucoma. There were no significant differences between the AROCs for other RNFL thickness parameters from Cirrus HD-OCT and Stratus OCT in preperimetric and early glaucoma (P＞0.05). Conclusion: Significant differences and an excellent correlation were noted in terms of RNFL thickness measurements using Stratus OCT and Cirrus HD-OCT. Cirrus HD-OCT presented higher diagnostic ability for preperimetric glaucoma.
