Objective: To measure the adherence to ophthalmology follow-up and the related health belief of patients with diabetes in medical alliance, and analyze the influencing factors. Methods: Totally 334 community-dwelling patients with diabetes mellitus were recruited in a medical alliance in Guangzhou by convenient sampling method. They were investigated by the Chinese version of the Compliance with Annual Diabetic Eye Exams Survey (CADEES-C). Results: Dilated fundus examination within the last year were only reported by 24.3% of respondents. The mean score of the CADEES-C was 3.09±0.64, with the highest score in perceived benefit and threat dimensions and the lowest score in behavioral cue dimension. The factors that mainly influence the adherence to ophthalmology follow-up and their related health beliefs of patients with diabetes are types of diabetes, propensity to seek treatment, other complications of diabetes, knowledge of medical alliance and family pattern. Conclusion: The adherence to ophthalmology follow-up and the related health belief of patients with diabetes are at low level with the deficiency of behavioral cues. It is suggested that medical alliance should play a critical role to improve the status quo by developing more screening and referrals.

目的：观察学龄儿童的近视进展情况，分析近视进展的危险因素。方法：于2014年纳入温州2所小学二、三年级近视儿童，每年随访1次，直至小学毕业。检查内容包括非睫状肌麻痹主觉验光、双眼视功能检查(隐斜、调节性集合/调节、正负相对调节、正负融像性聚散)和问卷调查。采用无序多分类logistic回归分析近视进展速度的危险因素。结果：共纳入152名近视儿童[年龄7~9岁，95名(62.5%)男性]，初始屈光度为-1.30±0.95屈光度(diopter，D)，年近视进展量为-0.68±0.35 D。回归分析表明：与慢速组相比(年近视进展量>-0.50 D)，中速组(-1.00 D<年近视进展量≤-0.50 D)与快速组(年近视进展量≤-1.00 D)中初始屈光度≤-1.00 D的儿童占比更大(中速组：OR=3.51，P=0.003；快速组：OR=3.29，P=0.044)，快速组中女性占比更大(OR=4.52，P=0.012)，基线双眼视功能参数在不同组间差异均无统计学意义(均P>0.05)。结论：学龄儿童近视进展速度与性别、初始屈光度相关，与基线双眼视功能无关。女孩、初始近视程度大(7~9岁时，屈光度≤-1.00 D)的儿童近视进展快。

Objective: To investigate myopia progression and analyze the risk factors associated with myopia progression in a cohort of primary schoolchildren. Methods: The study was conducted in two primary schools in Wenzhou. Schoolchildren from grades 2 and 3 were examined in 2014 and were followed up annually until primary school graduation at grade 6. Children who were myopic at baseline were included in this study. The examination included non-cycloplegic subjective refraction, questionnaire survey, and binocular visual function parameters such as phoria, accommodative convergence/accommodation, positive relative accommodation, negative relative accommodation, and fusional convergence range. Multinomial logistic regression analysis was conducted to investigate the risk factors associated with various myopia progression speeds. Results: A total of 152 myopic schoolchildren [baseline age range 7–9 years; 95 male (62.5%)] were included in this study. The average refractive error (spherical equivalent refraction, SER) at baseline was -1.30±0.95 D, and the average annual myopia progression was -0.68±0.35 D. Multinomial logistic regression analysis showed that compared to the slow myopia progression group (annual myopia progression >-0.50 D), the moderate myopia progression group (-1.00 D < annual myopia progression ≤-0.50 D) and the fast myopia progression group (annual myopia progression ≤-1.00 D) were associated with having SER values ≤-1.00 D at baseline (moderate: OR=3.51, P=0.003; fast: OR=3.29, P=0.044); the fast myopia progression group was also associated with female sex (OR=4.52, P=0.012); baseline binocular visual function parameters were not related to various myopia progression speeds (P>0.05 for all). Conclusion: Sex and baseline refractive error were associated with various myopia progression among primary schoolchildren. No correlation between baseline binocular visual functions and myopia progression was found in this study. Myopia progressed faster in girls and children who had greater myopia (SER values ≤?1.00 D at age 7–9 years) at baseline.

目的：评估屈光不正患者有晶体眼后房型人工晶体(implantable collamer lens，ICL)植入术后视疲劳症状及调节集合功能、眼表、像差的变化，并探讨其对视疲劳症状的影响。方法：前瞻性病例观察分析。连续收集在沧州市中心医院行ICL手术并完成3个月随访的患者，测定术前、术后1周、1个月、3个月时的视疲劳评分、调节幅度(amplitude of accommodation，AA)、正相对调节和负相对调节(positive/negative relative accommodation，PRA/NRA)、调节灵敏度(accommodative facility，AF)、调节性集合(accommodative convergence，AC)与调节(accommodation，A)比率(AC/A)，Schirmer实验、非侵入性泪膜破裂时间(noninvasive breakup time，NBUT)及高阶像差(higher order aberration，HOA)，进行统计学分析。结果：ICL术后第1周视疲劳症状较术前明显加重，随时间推移逐渐减轻，术后1个月仍高于术前，术后3个月时恢复。AA术后1周时较术前降低，术后1个月、3个月时明显高于术前；AF术后1周时较术前下降，术后1个月比术前水平稍好，3个月时明显高于术前；PRA、NRA无明显变化；AC/A术后1周时较术前下降，术后1个月回复到术前水平，术后3个月较术前提高。术后1周、1个月及3个月的NBUT值均较术前明显下降，术后1周时最低；Schiermer值术后1周时轻度下降，术后1个月、3个月时基本恢复。术后的总HOA均较术前有所增加，但各个时间点之间无明显变化。相关性分析显示ICL术后AF越差、NBUT越低，视疲劳症状越重。结论：ICL术后视疲劳症状一过性加重，AF和NBUT是影响视疲劳变化的重要因素。

Objective: To evaluate the changes of visual fatigue symptoms, accommodative functions, ocular surface conditions, and high-order aberrations (HOA) after implantation of implantable collamer lens (ICL), and to explore their effects on asthenopia. Methods: It was a prospective observational case series. Patients with ametropia who underwent ICL surgeries and completed 3-month follow-up in our hospital were enrolled.Asthenopia scores, amplitude of accommodation (AA), positive/negative relative accommodation (PRA/NRA),accommodative facility (AF), the ratio of accommodative convergence and accommodation (AC/A), Schirmer test, non-invasive breakup time (NBUT), and HOA were examined before surgeries and at 1 week, 1 month and 3 months after surgeries, then statistically analyzed. Results: Symptoms of asthenopia were significantly worse at 1 week after ICL surgeries than those before surgeries, but increased gradually as time went by, eventually recovered at 3 months postoperatively. Among regulatory indicators, AA decreased 1 week postoperatively, but was significantly higher at 1 and 3 months after surgeries; AF was lower 1 week after surgery than baseline, slightly better at 1 month postoperatively, and significantly higher at 3 months postoperatively; PRA and NRA had no significant change; AC/A decreased 1 week after surgeries, returned to the baseline at 1 month postoperatively, and increased 3 months postoperatively. Tears and meibomian gland function index: NBUT values at 1 week, 1 month and 3 months after surgeries were significantly decreased compared with those before surgeries, and NBUT at 1 week postoperatively was the lowest; Schiermer values had a slight decrease at 1 week after surgeries, and basically recovered at 1 and 3 months after surgeries. HOA after surgeries were increased compared with those before surgeries, but there was no significant change between each time point. Correlation analysis showed that the lower AF and NBUT after ICL surgeries, the more severe the asthenopia symptoms. Conclusion: The symptoms of asthenopia aggravated transiently after ICL implantation surgeries, but improved gradually with time. AF and NBUT were important factors affecting the changes of asthenopia.

[摘　要] 目的：研究准分子激光原位角膜磨镶术(laser in situkeratomileusis，LASIK)前后角膜滞后量(corneal hysteresis，CH)和角膜阻力因子(corneal resistance factor，CRF)变化量，对其相关因素进行多元线性回归分析。方法：前瞻性研究。纳入行LASIK手术的近视眼及近视散光患者70眼(38例)，术前与术后6个月各项参数分别由眼反应分析仪(ocular response analyzer，ORA)、非接触眼压仪、超声角膜测厚仪及Pentacam眼前节分析仪测量。分析LASIK手术前后△CH，△CRF与术前、手术设计等参数的相关性，并对相关参数进行多元线性回归分析。结果：手术前后CH分别为(10.05±1.36)，(8.15±0.90) mmHg(1 mmHg=0.133 kPa)，CRF分别为(9.91±1.38)，(6.92±0.88) mmHg，差异均有统计学意义(P<0.01)；△CH与△CRF分别为(1.90±1.15)，(2.99±1.23) mmHg。△CH与术前CH，CRF，眼压(intraocular pressure，IOP)，预计切削深度(ablative depth，AD)以及AD/CCT呈正相关；△CRF与术前CH，CRF，IOP，AD，AD/CCT，术前等值球镜(spherical equivalent，SE)以及预计 基质床厚度(residual stromal bed’s thickness，RSBT)有相关性。采用多元线性回归对LASIK手术前后△CH，△CRF与术前、手术设计等各相关参数进行分析，回归方程为：△CH=?6.182+0.658CH术前+8.421AD/CCT (R2=0.639，P<0.01)，△CRF=?0.007+0.725CRF术前?0.014RSBT (R2=0.689，P<0.01)。结论：LASIK术前后CH与预计AD和角膜厚度比值密切相关，CRF变化量与预计角膜RSBT密切相关，在设计手术时应慎重考虑预计AD与预计RSBT。

Abstract 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. The 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 andafter LASIK were (9.91±1.38) and (6.92±0.88) mmHg. There was significant 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. The regression equation of △CH and △CRF and influencing factors were △CH =?6.182 + 0.658CHpreoperative + 8.421AD/CCT (R2=0.639, P<0.01), △CRF =?0.007 + 0.725CRFpreoperative ? 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.

幽门螺杆菌(Helicobacter pylori，H P)感染是中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy，CSC)的一个危险因素，但是在HP感染和CSC相关性的研究仍存在争议，目前有两种观点：一是认为HP感染可能是CSC的一个危险因素，二是认为两者之间并没有相关性。本文将就对HP感染是否为CSC危险因素文献进行综述，同时探讨其发病机制。

Helicobacter pylori (HP) infection is a risk factor for central serous chorioretinopathy (CSC). But the existing studies tend to support two distinctively different trends regarding the link between HP infection and CSC. The first group tend to support that: HP infection may be a risk of CSC, and the second tend to claim to no correlation between the two. This paper will review the literature on whether HP infection is a risk factor for CSC and discuss its pathogenesis.

目的：探究角膜塑形镜(OK镜)配戴者使用中的镜盒的葡萄球菌及假单胞菌污染状况以及其可能存在的危险因素。方法：于四川大学华西医院隐形眼镜门诊收集镜盒使用1个月及以上的O K镜复查患者，使用问卷调查其基本信息与日常配戴情况，并收集其镜盒。收集的镜盒于无菌操作台内取样后转移入葡萄球菌选择培养基与假单胞菌选择培养基，置于37 ℃恒温培养箱中培养48 h后观察微生物生长情况。结果：本研究共收集受试者52例，其中男15例，女37例，年龄(11.8±2.5)岁。在收集的镜盒中，葡萄球菌的检出率为42%(22例)，其中金黄色葡萄球菌检出率为21%(11例)；假单胞菌的检出率为12%(6例)，未发现铜绿假单胞菌，总体微生物检出率为44%(23例)。存放于客厅或书房的镜盒微生物检出率为25%(5/20)，日常存放于卧室或卫生间的镜盒(58%，18/31)。日常护理由家长完成的镜盒微生物检出率为31%(10/32)，由戴镜儿童本人完成的镜盒微生物检出率为65%(13/20)。随着镜盒使用时间的增加，镜盒内微生物的检出率的增加差异无统计学意义。结论：OK镜戴镜者日常使用的镜盒中，葡萄球菌的污染率较高，其中相当一部分是金黄色葡萄球菌。日常护理操作人员、镜盒存放位置是镜盒污染的危险因素。镜盒使用的时间可能是镜盒微生物污染的危险因素，但是需要进一步的实验验证。

Objective: To investigate microbial contamination in Ortho-K wearer’s lens cases caused by Staphylococcus and Pseudomonas and to solicit its risk factors. Methods: Lens cases used for at least 1 month were collected from Ortho-K wearers coming back for after-care in West China Hospital and an interview using preset questionnaire about their demographic information and lens wearing was performed. Lens cases were sampled in clean bench and the samples were then transferred onto Staphylococcus selective agar plate and Pseudomonas selective agar plate, which were incubated at 37 ℃ for 48 h before observed. Results: A total of 52 subjects were recruited, including 15 male and 37 female, with an average age of (11.8±2.5) years. Contamination rate of Staphylococcus was 42% (n=22), in which 21% (n=11) were detected with Staphylococcus Aureus (SA). With no Pseudomonas Aeruginosa (PA) was detected, the general rate of microbial contamination was 44% (n=23). Contamination rate of cases stored in living room was 25% (5/20), significantly lower than cases stored in bedroom (58%, 18/31). And cases that daily cleaning operated by parents (31%) (10/32) were less contaminated than that operated by children themselves (65%) (13/20). The increase of detection rate of microorganism in lens cases didn’t reach a significant statistical difference with longer use. Conclusion: The contamination rate of Staphylococcus, in which a considerable part was contributed by SA, is high in Ortho-K lens cases. Personnel of daily cleaning and location of case storage are the risk factors of lens case contamination. Length of case use could be a potential risk of microbial contamination but remains to be proved by further research.
