目的：研究早产儿视网膜病变患儿经不同治疗措施后屈光状态的改变。方法：将72例(127眼)早产儿视网膜病变患儿按治疗方式分为3组：激光光凝组、注药(抗血管内皮生长因子药物)组和自然消退组。并于治疗前，治疗后1、4、7、12个月对其进行睫状肌麻痹检影验光，对比分析3组的球镜和等效球镜的差异。结果：在治疗后1、4、7及12个月，三组患儿的球镜度和等效球镜度的差异有统计学意义(P<0.05)：注药组的球镜和等效球镜小于自然退化组及激光组(均P0.05)。治疗后12个月时激光光凝组、注药组和自然消退组近视发生率分别是2.4%、7.8%和2.0%，差异无统计学意义(P=0.356)。结论：经不同治疗措施的ROP患儿近视发生率无明显差异，但经玻璃体腔注射抗VEGF药物的ROP患儿正视化进程更快。

Objective: To observe the changes of refractive statues in infants with retinopathy of prematurity retinopathyof prematurity (ROP) after different treatments. Methods: According to different treatment methods, 72 cases(127 eyes) of infants with ROP were divided into 3 groups: laser photocoagulation group, intravitreal injectionof anti-vascular endothelial growth factor (VEGF) drugs group and natural regression group. Their sphere andspherical equivalent were measured by retinoscopy optometrist after the ciliary muscles paralyzed. The data beforetreatments and 1, 4, 7 and 12 months after treatments were recorded and analyzed. Results: The differences ofsphere and spherical equivalent among three groups were statistically significant: intravitreal injection of VEGFdrugs group was lower than natural regression group and the laser photocoagulation group, but there was no significant difference between natural regression group and laser photocoagulation group. Incidence of myopiaof laser photocoagulation, intravitreal injection of VEGF drugs, natural regression group were 2.4%, 7.8%, 2.0%,which was not statistically significant. Conclusion: There was no significant difference about the incidence rate ofmyopia among the three groups, but the emmetropization in infants with ROP after intravitreal injection of anti-VEGF drugs might be faster in the future.

临床上内源性真菌性眼内炎比较少见，其早期临床表现因类似于葡萄膜炎等常见眼病常常被误诊。武汉爱尔眼科医院汉口医院收治了1例49岁女性患者，首诊为葡萄膜炎，后前房穿刺送检确诊为内源性念珠菌性眼内炎。

Endogenous fungal endophthalmitis is easy to be misdiagnosed because it is quite rare and early clinical features resembling uveitis. A 48-year-old female patient was admitted to Wuhan Aier Eye Hospital Hankou Hospital, her first diagnosis was uveitis, and the posterior anterior chamber puncture was confirmed as endogenous Candida endophthalmitis.

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.

糖尿病视网膜病变(diabetic retinopathy，DR)在糖尿病肾病(diabetic nephropathy，DN)人群，特别是终末期糖尿病肾病(end stage diabetic nephropathy，ESRD)患者中的发病率和严重程度明显高于糖尿病人群。其中ESRD的一项重要治疗手段——血液透析(Hemodialysis，HD)可能会增加机体氧化应激反应、出血风险以及视神经的缺血缺氧，加重DR的发生发展；但另一方面也可通过清除尿毒症毒素、控制血压以及清除多余体液等途径改善糖尿病和DN对眼部的损伤。

The incidence and severity of diabetic retinopathy (DR) in patients with diabetic nephropathy (DN), especially those with end-stage renal disease (ESRD), were higher than those with diabetes. Hemodialysis (HD), an important treatment of ESRD, may aggravate DR by increasing the oxidative stress, fundus hemorrhage and hypoxia of the optic nerve. On the other hand, HD can improve the ocular damage caused by diabetes mellitus and DN by removing uremia toxin, controlling blood pressure and removing excess body fluid.

Objective: To explore the application of children’s binocular vision screening instrument in screening congenital cataract. Methods: This was a retrospective analysis of 336 infants aged 3 months to 2 years (672 eyes) who were admitted to the Ophthalmology Department of Xiamen Children's Hospital from July 2017 to May 2018. They were examined by two fixed doctors with the pupil red light reflex and binocular vision screening instrument, and the medical history was recorded in details. All the children received slit lamp examination, compound tropicamide mydriasis and fundus examination. If necessary, the children who could not see fundus were given with B-ultrasonic examination or MRI examination. Results: According to the clinical classification of congenital cataracts published in the 5th edition of Harley’s pediatric ophthalmology in 2009, In this group, there were 27 cases (35 eyes) of congenital cataract, including 2 cases (4 eyes) of embryonic nucleus, 23 cases (29 eyes) of lamellar layer, 2 cases (2 eyes) of nuclear cataract, 19 cases (28 eyes) of capsular cataract, 2 cases (4 eyes) of suture cataract, 3 cases (6 eyes) of polar cataract and 2 cases (3 eyes) of total cataract. The sensitivity of children’s binocular vision screening instrument screening congenital cataract was 81.58%, the specificity was 79.87%, and the diagnostic coincidence rate was 80.06%; the sensitivity of red reflection screening congenital cataract was 51.32%, the specificity was 69.97%, and the diagnostic coincidence rate was 67.86%; the results of the two groups were statistically significant. The screening rate of children's binocular vision screening instrument for cortical (nuclear) cataract was 97.14%, while that of red reflex was 37.14%. The results were statistically significant. Conclusion: In the screening of congenital cataract, the binocular vision screening instrument for children has the advantages of low missed diagnosis rate, high misdiagnosis rate and high diagnostic consistency, especially for cortical (nuclear) cataract. It is helpful to find the congenital cataract early in the auxiliary screening of children’cares eye health

本文对7例正常人眼前房角小梁网进行了组织化学——酸性粘多糖及超微结构的研究。结果表明人类正常眼前房角小梁中存在酸性粘多糖,以内皮网处较多,大部分可被透明质酸酶消化。小梁带中螺旋纤维可能是小梁网柔韧性的结构基础,小梁带基板层与小梁带内皮细胞胞浆存在密切联系,小梁内皮细胞间的连接,可能对防止小梁带受外界因素影响而发生位移有一定稳固作用,内皮网间质中存在Ⅰ、Ⅱ型斑状物及胶原成分,39岁以下眼中含量较少,老年眼中较多。Schlemm 氏管内壁内皮细胞胞浆中液泡是房水排出的细胞内途径,证实了本文作者1963年提出的论点。

Histochemical and ultrastructural studies of the trabecular meshwork (TM) of 7 normal human eyes were carried out. The age of this group ranged between 20-70 years. Histochemical results showed that acid mucopolysaccharides existed in the TM of normal eyes, especially in the endothelial meshwork portion. Most of the acid mucopoly-saccharides were digestible by testicular hyaluronidase. The ultrastructural study indicated the following: 1. The spiral fibrils surrounding the collagen core of TM were spaced unequally in spiral distance and might wind loosely or tightly. This structure might be the anatomic basis of the flexibility of the trabeculae, 2. The discontinuous cytoplasmic membrane of the endothelium and the extention of the basal lamina to the endothelial cytoplasm as a process-like structure might imply that there were substances exchanged between the endothelial cells and the basal lamina of the trabeculae. 3. The structures known as tongue-in-groove and interdigitation joints were desmosomes or gap junctions between the adjacent cell membrane. These two junctional structures might act as stabilizers to prevent trabecular bands from moving when effected by outer environment. 4. The vacuoles within the cytoplasm of the endothelial cell lining the inner wall of Schlemm's canal might indicate that the aqueous outflow passes through intracellular path-way. This evidence confirmed our suggestion in 1963 which is consistent with many authors' idea.
