目的：评价海藻糖滴眼液对摘除眶内眶外泪腺的实验性大鼠干眼的疗效。方法：SD 大鼠 30 只，随机分成正常组、对照组、实验组，每组 10 只（20 只眼）。正常组不给予处置，实验组和对照组通过摘除大鼠主泪腺制作干眼动物模型。对照组和实验组于造模完成术后 1 周后分别给予生理盐水、海藻糖滴眼液点双眼，每天 4 次，治疗共 4 周。分别于造模术前和造模术后 1、2、3、5 周进行基础泪液分泌试验（Shirmer I test），角膜上皮荧光染色评分检测；造模 5 周后将大鼠处死，采用免疫组织化学方法对结膜上皮细胞中 Bcl-2 和 Bax 凋亡基因蛋白表达进行检测，观察干眼动物模型结膜上皮细胞凋亡与眼表干眼病变及组织损伤的关系。结果：基础泪液分泌试验结果显示，对照组和实验组除术后第 5 周比较差异有统计学意义外（P < 0.05），其余时间点差异无统计学意义（P > 0.05），术后各时间点与正常组比较差异均有统计学意义（P < 0.05）。造模术后第 1 周，对照组和实验组角膜荧光染色评分明显高于正常组；术后第 2 周后，对照组和实验组评分差异无统计学意义（P > 0.05），随着时间的延长，术后第 3 周和第 5 周，两组评分差异均有统计学意义（P < 0.05），且实验组评分小于对照组。结膜上皮细胞免疫组织化学检测结果显示：正常组结膜上皮细胞 Bax 蛋白阳性表达的细胞数较对照组和实验组少，与对照组比较，差异有统计学意义（P < 0.05），与实验组比较差异无统计学意义（P > 0.05）；正常组可见大量 Bcl-2 蛋白阳性表达，且多于实验组，差异无统计学意义（P > 0.05），多于对照组，差异有统计学意义（P < 0.05）；对照组结膜上皮细胞中可见大量 Bax 蛋白阳性表达于细胞质，呈棕黄色颗粒，实验组中 Bax 蛋白阳性表达相对于对照组明显较少，两者差异有统计学意义（P < 0.05）；实验组结膜上皮细胞中可见大量 Bcl-2 蛋白阳性表达，对照组 Bcl-2 蛋白表达相对于实验组明显减少，差异有统计学意义（P < 0.05）。结论：海藻糖滴眼液可以减少角膜表层上皮脱落，对结膜上皮细胞有一定的保护作用，可以拮抗结膜上皮细胞的凋亡，从而增强角结膜上皮屏障功能，改善由干燥引起的眼表上皮的损伤。海藻糖溶液可用于眼表上皮疾病的潜在临床应用，为治疗眼表疾病如干眼症提供治疗选择。

Objective: To observe the efficacy of trehalose eye drops on experimental dry eye rat with removal of inside and outside lacrimal glands. Methods: A total of 30 SD rats were randomly divided into a normal group, a control group, and an experimental group, with 10 rats for each group (20 eyes). The normal group was not treated, and the experimental group and the control group were made into a dry eye animal model by removing the main lacrimal gland of the rat. The control group and the experimental group were given with normal saline and trehalose eye drops once a week after the completion of modeling, 4 times a day for 4 weeks. Shirmer I test and fluorescence staining test were carded before and 1, 2, 3, and 5 weeks after modeling. After 5 weeks of modeling, the rats were sacrificed and the expression of Bcl-2 and Bax apoptosis protein in conjunctival epithelial cells was detected by immunohistochemistry in order to observe the relationship between apoptosis of conjunctival epithelial cells and dry eye lesions and tissue damage in dry eye animal models. Results: Schirme I test results showed that there was no significant difference between the control group and the experimental group (P > 0.05) except for the 5th week after operation (P < 0.05). There was a statistical difference between the two groups and the normal group at each time point after surgery (P < 0.05). At the first week after modeling, the corneal fluorescence staining scores of the control group and the experimental group were significantly higher than those of the normal group. After the second week after surgery, there was no significant difference between the control group and the experimental group (P > 0.05). The prolongation of time, the 3 week and the 5th week after surgery, the difference between the two groups was statistically significant (P < 0.05), and the score of the experimental group was smaller than the control group. The immunohistochemical results of conjunctival epithelial cells showed that the number of Bax protein positive cells in the normal conjunctival epithelial cells was less than that in the control group and the experimental group. The difference between the normal group and the control group was statistically significant (P < 0.05). There was no significant difference between the two groups (P > 0.05). There was a large amount of Bcl-2 protein in the normal group, which was more than the experimental group. The difference was not statistically significant (P > 0.05), which was more than the control group. The difference was statistically significant (P < 0.05); a large amount of Bax protein was positively expressed in the cytoplasm and brownish-yellow particles in the conjunctival epithelial cells of the control group. The positive expression of Bax protein in the experimental group was significantly less than that in the control group, and the difference was statistically significant (P < 0.05). A large amount of Bcl-2 protein was positively expressed in the conjunctival epithelial cells of the experimental group, and the expression of Bcl-2 protein in the control group was significantly decreased compared with the experimental group (P < 0.05).Conclusion: Trehalose eye drops can reduce epithelial detachment of the cornea and have a protective effect on conjunctival epithelial cells, which can antagonize the apoptosis of conjunctival epithelial cells, thereby enhancing the keratoconjunctival barrier function and improving the ocular surface epithelium caused bydryness. The potential clinical application of trehalose solution for ocular surface epithelial diseases and provide treatment options for ocular surface diseases, such as dry eye.

目的：探讨高度近视合并白内障患者白内障术后有效晶状体位置的变化。方法：收集白内障超声乳化摘除联合人工晶状体植入术的高度近视合并白内障患者 21 例共 27 眼，记录术后 1 d、1 周、1 个月视力、屈光度、有效晶状体位置。结果：高度近视合并白内障患者术后 1 d、1 周、1 个月有效晶状体位置分别为（4.17±0.39），（4.09±0.38），（4.31±0.44） mm，且组间比较差异有统计学意义（P < 0.05）。有效晶状体位置的实际轴向运动为（0.19±0.13） mm，与晶状体厚度呈正相关（r = 0.648，P < 0.001），与术前眼轴无相关关系（r = 0.227，P = 0.255）。结论：高度近视合并白内障患者术后 1 d 至 1 周人工晶状体轻度前移而造成近视偏移，而术后 1 个月时则呈远视偏移，且术后有效晶状体位置位移与术前晶状体厚度相关。

Objective: To investigate the change and influencing factors of the effective lens position after cataract surgery in high myopia eyes. Methods: We collected 27 eyes of 21 patients with high myopia who underwent phacoemulsification and intraocular lens implantation. The visual acuity, diopter and effective lens position were recorded 1 day, 1 week, and 1 month after operation. Results: The effective lens position of high myopia combined with cataract patients at 1 day, 1 week, and 1 month was (4.17±0.39), (4.09±0.38), and (4.31±0.44) mm, respectively. The effective lens positions significantly differed between the groups after surgery (P < 0.05). The ELPRMS was (0.19±0.13) mm. The ELPRMS was positively correlated with the lens thickness (r = 0.648, P < 0.001),whereas was not correlated with the preoperative axial length (r = 0.227, P = 0.255). Conclusion: High myopic patients with cataract have a slight forward movement of the effective lens position from 1 day to 1 week after surgery, and a hyperopic shift from 1 week to 1 month. The displacement of effective lens position after surgery is correlated with the preoperative lens thickness.

Objectives: To evaluate the clinical value of peripheral retinal diseases in myopic patients examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona). Methods: This was a prospective case-control study. We collected 1 000 myopic patients (2 000 eyes) who were scheduled to undergo refractive surgery in Aier Eye Hospital. They were examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona) with non-mydriasis and three-mirror contact lens with mydriasis. The examination results were recorded and statistically analyzed. Results: A total of 230 cases (310 eyes) with peripheral retinopathy were found by 200-degree ultra-wide field laser ophthalmoscope (Daytona). The positive rate was 15.50%; 242 cases (322 eyes) with peripheral retinopathy were found by threemirror contact lens, and the positive rate was 16.10%. The two methods were consistent in the detection of peripheral Retinopathy in myopic patients (the Kappa value is between 0.8 and 1.0). Conclusion: 200-degree ultra-wide field laser ophthalmoscope (Daytona) is an effective and rapid method for detecting peripheral retinopathy. It provides a broad clinical application prospects for peripheral retinopathy screening before refractive surgery. 

教学查房是手把手教学的重要手段和具体表现，是让同学们把书本知识应用到医疗诊疗中的重要桥梁。眼科学具有形象生动、结构复杂、直观性和操作性强等特点。外眼疾病的特征更是显而易见，针对外眼疾病诊疗中的一些不规范的操作也更易暴露出来。本文以上睑下垂为例，旨在阐明教学查房在外眼疾病教学中的重要性。

Teaching rounds are an important means and concrete manifestation of hands-on teaching, and an important bridge for students to apply book knowledge to medical diagnosis and treatment. Ophthalmology has the characteristics of vivid image, complex structure, intuition and strong operability. The characteristics of external eye diseases are more obvious, and some non-standard operations in the diagnosis and treatment of external eye diseases are easier to expose. This article takes blepharoptosis as an example to illustrate the importance of teaching rounds in the teaching of external eye diseases.
