目的：探索一种无创的、智能可穿戴设备监测学龄儿童量化的用眼行为，并定量分析近视发生的相关因素。方法：招募佛山市禅城区石湾第二小学三年级及狮城中学小学部五年级的年龄为7~11岁部分学生共171例。所有受试者均按照非睫状肌麻痹主觉验光结果分为近视组108例和非近视组63例，所有受试者均佩戴智能可穿戴设备“云夹”，进行为期10 d(2022年9月21日—2022年10月2日)的用眼行为数据(近距离用眼距离、近距离用眼时间、近距离环境光照、有效户外时间)采集。采用t检验比较近视组与非近视组儿童在用眼行为数据之间的差异，并应用Logistic回归分析用眼行为与近视发生的相关性。绘制受试者操作特征(receiver operating characteristic curve,ROC)曲线，并计算曲线下面积(area undercurve,AUC)分析用眼行为习惯对近视发生的预测价值。结果：学龄期儿童近视患病率为63.2%。近视组与非近视组在每天用眼时间、单次用眼时间、用眼距离、白天用眼光照、晚上用眼光照、每天户外活动时间及每天有效户外活动暴露次数比较差异均有统计学意义(均P＜0.05)。Logistic回归分析显示，单次用眼时间、每天用眼时间是近视发生的危险因素。Spearman相关性分析显示，单次用眼时间及每天用眼时间均与近视发生呈正相关(均P＜0.05)。单次用眼时间预测近视发生的ROC曲线下面积为0.939。结论：可穿戴设备“云夹”可量化学龄期儿童用眼行为；学龄期儿童近视发生可能与近距离用眼时间有一定相关性；预测模型可结合儿童屈光发育档案，量化近视发生风险，对儿童实现分类管理，及时采取个性化干预。

Objective: To investigate a non-invasive,smart device capable of monitoring the quantitative visual behavior of school age children, and to analyze quantitatively the relationship between visual behavior and the occurrence of myopia. Methods: This study recruited 171 subjects aged between 7 and 11 years from the third grade of Shiwan SecondPrimary School and the fifth grade of Shicheng Middle School in Chancheng District, Foshan City. Participants werecategorized into a myopia group (108 subjects) and a non-myopia group (63 subjects) based on results from non-ciliary muscle paralysis optometry. All subjects wore "clips" to track their near-work distance, near-work duration, lighting conditions during near-work, and time spent on outdoor activities between September 21, 2020, and October 10, 2020. Differences in these habits between the myopia and non-myopia groups were compared, and logistic regression analysis was conducted to assess the impact of habitual eye use on myopia. Results: The prevalence of myopia was found to be 63.2%. Statistically significant differences (all P<0.05) were observed between the myopic and non-myopic groups regarding average daily near-work time, average single near-work session duration, average near-work distance, average daytime and nighttime near-work lighting conditions, average daily outdoor activity time, and average daily effective outdoor activity exposure. Logistic regression analysis indicated that longer average single near-work sessions and increased average daily near-work time were risk factors for myopia. Spearman correlation analysis further supported these findings, showing a positive correlation between average single near-work session duration and average daily  near-work time with the occurrence of myopia (all P<0.05). The predictive accuracy of a model combining average single near-work session duration and average daily near-work time for myopia occurrence was high, with an area under the curve of 0.939. Conclusions: The wearable device "Cloud clip" effectively monitors the visual behavior of school-age children. The occurrence of myopia in this age group may be associated with increased near-work activities. A predictive model incorporating refractive development in myopic children can assess the quantitative risk of myopia, enabling the classification and management of school-age children. Personalized interventions may serve as protective factors against myopia.

目的：探讨青光眼日间手术患者的自我管理行为现状及影响因素分析。方法：采用便利抽样法选取2021年9月—2022年5月于广州市某三级甲等眼科专科医院就诊的223例青光眼日间手术患者。采用一般资料调查表、青光眼自我管理行为量表、慢性疾病自我效能量表和青光眼知识学习问卷进行问卷调查。结果：青光眼日间手术患者的自我管理行为得分为(54.03±6.95)分，其中生活调整维度得分最低。慢性病自我效能与自我管理行为呈正相关(r=0.368, P<0.001)。疾病知识与自我管理行为无显著相关性(r=0.077, P=0.252)。多因素线性回归分析结果显示，患者的文化程度(P<0.001)和自我效能(P=0.028)是自我管理行为的影响因素，可解释自我管理行为总变异的12.4%。结论：青光眼日间手术患者具有良好的自我管理行为，较低的自我效能和文化程度是自我管理行为的危险因素，因此应优先提高患者的自我效能，并提供个性化教育。

Objective: To determine self-management and its association with self-efficacy and knowledge among glaucoma patients undergoing day surgery. Methods: A total of 223 glaucoma patients were recruited from September 2021 to May 2022and they were investigated with the Glaucoma Self Management Questionnaire (GSMQ), The Self- Efficacy in Chronic Disease Scale (SECD-6), and the glaucoma knowledge questionnaire. Results: Of the 223 study participants, the study population had a total GSMQ score of 54.03±6.95 with the lowest score found in the life adjustment dimension. The total SECD-6 score was showing a significantly positive correlation with the total GSMQ score(r =0.368, P <0.001). The total score of disease knowledge was without significant correlation with the total GSMQ score (r =0.077, P =0.252). Multivariate linear regression analysis showed that self-efficacy (P <0.001) and education level was independently associated with self-management(P =0.028). Conclusions: Glaucoma patients undergoing daytime surgery demonstrated good overall self-management, yet further improvement was required in terms of life adjustment. Low self-efficacy and educational level were identified as risk factors for self-management. Therefore, self-management programs should prioritize enhancing patients' self-efficacy and delivering individualized education.

目的：探讨白内障人群角膜屈光力(corneal refractive power,CRP)的分布特点及与眼生物学参数的相关因素分析。方法：回顾性横断面研究福州眼科医院2019年3月至2022年7月就诊的40岁以上白内障人群共23035眼，使用OA-2000测量其眼轴(axial length,AL)、CRP、前房深度(anterior chamber depth,ACD)、晶状体厚度(lens thickness,LT)、角膜水平直径即白到白(white-to-white,WTW)、中央角膜厚度(central corneal thickness,CCT)。绘制各眼生物学参数及年龄Spearman相关性热力图，绘制CRP与AL、CRP与WTW散点拟合图。将CRP与上述参数及年龄进行Spearman相关性分析，分段数据的线性关系使用Pearson分析及线性回归分析。结果：白内障人群CRP为(44.36±1.52)D，在总体数据中CRP与AL为非线性相关；但在分段数据中存在线性相关：当AL≤25.06 mm，CRP与AL负线性相关(R² =0.397，P<0.001)；当AL>25.06 mm，CRP与AL正线性相关(R² =0.045，P<0.001)；无论AL长短，CRP与WTW、CCT均呈负相关。在总体数据中，CRP与WTW也存在非线性关系；但在分段数据中存在线性相关：当10.52 mm≤WTW≤12.46 mm，CRP与WTW负线性相关(R² =0.149，P<0.001)，并与AL、ACD、CCT呈负相关。结论：CRP与AL、WTW呈非线性相关，使用CRP优化计算人工晶状体(intraocular lens,IOL)屈光力时需适当考虑AL、WTW与CRP的相关性。

Objective: To investigate the distribution characteristics of corneal refractive power (CRP), and analyze the correlation between corneal refractive power and ocular biometric parameters in cataract patients. Methods: A retrospective cross-sectional study was conducted on 2,3035 eyes of cataract patients over 40 years old, who visited Fuzhou Eye Hospital during the period between March 2019 and July 2022. The subjects' examination results of axial length (AL), corneal refractive power (CRP), anterior chamber depth (ACD), lens thickness (LT), horizontal corneal diameter (WTW), central corneal thickness (CCT) were measured by OA-2000. Spearman correlation thermograms of bilological parameters and age for each eyes were worked out. The plot scatter fitting plots of CRP and AL, CRP and WTW were made. Spearman correlation analysis was made among CRP, above-mentioned parameters and age. Linear relationships of the segmented data were analyzed with Pearson and linear regression analysis. Results: In the cataract patients, CRP was (44.36 ± 1.52) D. There was a non-linear correlation between CRP and AL in the total data. However, there was a linear relationship in the segmented data. When AL ≤ 25.06 mm, CRP was negatively linearly correlated with AL (R² =0.397, P<0.001). When AL>25.06 mm, CRP was weakly positively correlated with AL (R² =0.045, P<0.001). Regardless of the length of AL, CRP was negatively correlated with WTW and CCT. There was also a nonlinear relationship between CRP and WTW in the total data. But there was a linear correlation in the segmented data.When 10.52 mm ≤ WTW ≤ 12.46 mm, the negative linear correlation was found between CRP and WTW (R² =0.149, P<0.001), while there was negative correlation among CRP, AL, ACD, and CCT. Conclusion: There is a non-linear correlation among CRP, AL and WTW. To optimize the calculation of intraocular lens (IOL) refractive power with CRP, it is necessary to consider the correlation between AL, WTW, and CRP.

玻璃体切割术是目前临床上常见的眼科手术之一，其应用广泛，且具有良好的治疗效果，但术后仍会出现各种并发症，眼压升高便是其中常见的一种。玻璃体切割术后眼压升高的病因复杂多样，术前原发病的不同、术中处理方式的差异以及术后并发症均可引起眼压升高，根据不同的病因可以选用更合适的治疗方法。早期的眼压升高较易控制，主要采用药物及激光治疗，晚期眼压升高导致继发性青光眼则相对复杂，以手术治疗为主。该文主要对玻璃体切割术后高眼压的原因分析及治疗进展进行综述。

Pars plana vitrectomy is one of the common ophthalmic surgeries in clinic practice currently, which is widely used with good therapeutic effect. However, various complications may still occur after operation. Elevated intraocular pressure is one of common complications. The causes of postoperative ocular hypertension are complex and diverse. Elevated intraocular pressure could be caused by different preoperative primary diseases, intraoperative management methods,and postoperative complication. More appropriate treatment methods can be selected based on different causes. Early elevated intraocular pressure iseasier to control and is mainly treated with medicine and laser. Late elevated intraocular pressure leads to secondary glaucoma, which is relatively complex and mainly treated with surgery. This review mainly states causes and treatment progress of high intraocular pressure after vitrectomy.

Objective: To discuss the change of corneal hysteresis and corneal resistance factor before and after laser in situkeratomileusis (LASIK), and to analyze their related factors by multivariate linear regression. Methods: In this prospective study, 70 eyes (38 patients) with myopia and myopic astigmatism undergoing LASIK were included. Related factors were measured preoperatively and at 6 months postoperatively by ocular response analyzer, noncontact tonometer (NCT), ultrasonic pachymeter, and Pentacam system. TTe correlation was analyzed between △CH, △CRF and preoperative and operative design’s parameters, and correlative factors analyze. △CH and △CRF were analyzed by the multiple linear regression. Results: CH before and after LASIK were (10.05±1.36) and (8.15±0.90) mmHg, and CRF before and affer LASIK were (9.91±1.38) and (6.92±0.88) mmHg. TTere was signiffcant difference between preoperative and postoperative CH and CRF (P<0.01). △CH and △CRF were (1.90±1.15) and (2.99±1.23) mmHg. Preoperative CH, CRF, intraocular pressure (IOP), ablative depth (AD) and AD/CCT were positive correlated with △CH. Preoperative CH, CRF, IOP, AD, AD/CCT, preoperative spherical equivalent (SE) and predicted residual stromal bed’s thickness (RSBT) were correlated with △CRF. TTe regression equation of △CH and △CRF and influencing factors were △CH =?6.182 + 0.658CH_preoperative + 8.421AD/CCT (R2 =0.639, P<0.01), △CRF =?0.007 + 0.725CRF_preoperative ? 0.014RSBT (R2 =0.689, P<0.01). Conclusion: The change of CH before and after LASIK is correlative with AD/CCT. The change of CRF before and after LASIK is correlative with predicted residual stromal bed’s thickness. Ablative depth and predicted residual stromal bed’s thickness should be considered carefully during the surgical design.

目的：了解原发性开角型青光眼(primary open angle glaucoma，POAG)患者视野缺损的进展情况，探讨其发生进展的相关危险因素。方法：回顾性分析2014年1月至2018年7月就诊于北京大学第三医院眼科并有至少4次视野检查的POAG患者。按照患者首次视野检查的平均偏差或平均缺损进行分期。将历次随访视野检查的平均偏差或平均缺损与时间进行线性回归分析，取其斜率(dB/年)。根据平均偏差或平均缺损的斜率将患者分为进展组与无进展组。分析患者视盘周围视网膜神经纤维层(retinal nerve fiber layer，RNFL)厚度损害位置、平均随诊间隔时间、基线视野分期等因素与青光眼视野缺损进展的关系。结果：共纳入128例患者(252只眼)，其中129眼使用Octopus视野计检查随访，基线视野缺损值为(10.91±5.76) dB；123眼使用Humphrey视野计，基线视野偏差值为(–10.62±6.89) dB。视野缺损早、中、晚期的比例分别为26.19%、36.51%和37.30%。进展组31只眼(12.30%)，无进展组221只眼(87.70%)。上下方RNFL都存在重度损害的患者，其视野缺损更易进展(P<0.001)。平均随诊间隔时间≤4个月的患眼，发生进展的比例高于平均随诊间隔时间>4个月的患眼(P=0.058)。基线视野分期、年龄、性别、总随访时间与视野缺损进展未见显著相关性。结论：青光眼患者的视功能损害出现恶化是普遍存在的。上下方RNFL均存在重度损害、随诊间隔时间短与视野缺损进展相关。视神经结构的改变与功能损害具有相关性，结构改变的方位对功能损害进展有提示功能。规律随诊对病情监测有重要意义，对于可能快速进展的患者，应缩短随诊间隔时间。

Objective: To investigate the progression of visual field defect in primary open angle glaucoma (POAG), and to explore the related risk factors for its progression. Methods: A retrospective analysis was performed on patients with POAG who had at least 4 visual field examinations in the Department of Ophthalmology, Peking University Third Hospital from January 2014 to July 2018. The visual field was staged according to the mean deviation or mean defect of the first visual field examination. Linear regression analyses of mean deviation or mean defect were performed against time, and corresponding regression slopes (in decibels per year) were calculated. Patients were divided into progressive and non-progressive groups according to the mean deviation slope or mean defect slope. The relationship between retinal nerve fiber layer (RNFL) thickness lesion location, mean follow-up interval, baseline visual field staging, and the progression of visual field defect in glaucoma were analyzed. Results: A total of 128 patients (252 eyes) were included. Among them, 129 eyes were followed up with an Octopus perimeter, and the average mean defect value of the baseline visual field was 10.91±5.76 dB; while the other 123 eyes were followed up with a Humphrey perimeter, and the average mean deviation value of the baseline visual field was –10.62±6.89 dB. The proportion of early, middle and late visual field defects was 26.19%, 36.51% and 37.30%. There were 31 eyes (12.30%) in the progressive group and 221 eyes (87.70%) in the non-progressive group. Patients with severe damage to both the upper and lower RNFLs had more visual field defects (P<0.001). Patients with an average follow-up interval ≤4 months had a higher rate of progression than those with an average follow-up interval >4 months (P=0.058).There were no significant differences in baseline visual field stage, age, gender, and total follow-up time between the progression and progression-free groups. Conclusion: Deterioration of visual function impairment is common in glaucoma patients. The progression of visual field defects is associated with severe impairments which are present both in the upper and lower RNFLs, and short follow-up intervals. Optic nerve structure changes are related to functional impairment, and the location of structural changes is suggestive of functional impairment progression.Regular follow-up visits are of great significance for disease monitoring. For patients who may progress rapidly, the follow-up interval should be shortened.

目的：观察并分析不同类型黄斑裂孔的患病相关影响因素。方法：回顾性分析2012年1月 至2018年12月在兰州大学第二医院住院治疗的1 150例(1 202只眼)全层黄斑裂孔患者的年龄、性别、民族、最佳矫正视力、黄斑裂孔类型以及是否继发孔源性视网膜脱离等临床资料。结果：黄斑裂孔患病人数随年龄增长呈趋势性分布，60~69岁年龄段患病人数最多；男女患病差异有统计学意义(P<0.05)，眼别差异无统计学意义(P>0.05)；特发性黄斑裂孔继发孔源性视网膜脱离的占比明显低于其他类型；特发性黄斑裂孔的入院最佳矫正视力较高，与高度近视黄斑裂孔相比，差异有统计学意义(P<0.05)。结论：黄斑裂孔多发于老年人，女性多见，高度近视黄斑裂孔容易继发孔源性视网膜脱离，可考虑尽早安排手术治疗；外伤性黄斑裂孔好发于中青年男性，常见于眼球钝挫伤，若未引发视网膜脱离等并发症，应适当观察而不急于手术。每1例黄斑裂孔都可能有其特殊性，需要认真分析病情综合判断，酌情选择观察或手术。

Objective: To observe and analyze the disease related factors of different types of macular hole. Methods: Clinical data including age, sex, ethnicity, best corrected visual acuity, macular hole type and whether accompanied by rhegmatogenous retinal detachment were retrospectively analyzed in 1 150 patients (1 202 eyes) hospitalized in our hospital from January 2012 to December 2018. Results: The number of patients with macular hole increased with age. There was statistically significant difference between male and female patients (P<0.05), and no statistically significant difference between eyes (P>0.05). The rate of rhegmatogenous retinal detachment caused by idiopathic macular hole was significantly lower than other types. The optimal corrected visual acuity of idiopathic macular hole was higher in admission, which was statistically different from that of high myopia macular hole and ametropia macular hole (P<0.05). Conclusion: Macular hole is more common in the elderly and more common in women. High myopia and ametropia macular hole are easily associated with rhegmatogenous retinal detachment, so surgical treatment should be arranged as soon as possible. Traumatic macular hole often occurs in young and middle-aged men and is often seen in blunt contusion of the eyeball. Each case of macular hole may have its particularity, which requires careful analysis of the condition, comprehensive analysis, and appropriate choice of observation or surgery.
