Objective: To explore the ocular surface recovery after surgical treatment of strabismus patients. Methods: A total of 92 patients (126 eyes) with strabismus who underwent surgery in our hospital from January 2015 to June 2018 were enrolled. The patients were divided into three groups according to the surgical incision, 42 patients (52 eyes)underwent limbal incision were in group A, 17 patients (19 eyes) underwent trans-muscle end-point incision in group B, and 33 patients (55 eyes) underwent proximal hernia incision in group C. According to the number of muscles involved in the operation, the sick eyes of patients were divided into three groups. The 29 eyes with a single extraocular muscle were a single muscle group, the 42 eyes with 2 extraocular muscles were a double muscle group, and the 21-eye treated with 3 extraocular muscles were a three-muscle group. The ocular surface health recovery time of patients with different incision types and muscle involvement were compared. Results: The first tear film rupture recovery time and tear river height time between group A, B, and C were significantly different,and the data were statistically significant (P<0.05); the first tear film rupture recovery time (14.33±3.26) d and tear river height time (14.54±1.58) d in group A were significantly lower than those in group B and C. The data were statistically significant (F=4.876, P=0.032; F=4.612, P=0.036). The first tear film rupture recovery time and tear river height time between the single, double and three muscle groups were significantly different, and the data were statistically significant (P<0.05); the first tear film rupture recovery time (13.42±3.57) d and tear river height time (8.65±1.62) d were significantly lower in the single muscle group than in the double muscle group and the third muscle group. The data were statistically significant (F=4.975, P=0.028; F=5.024, P=0.025). Conclusion:The number of muscles involved in the operation and the type of surgical incision have an important impact on the health of the ocular surface after surgery. The proximal ankle incision and less number of muscles involved would improve the postoperative recovery of eye health.
目的：比较不同受检者在相同近视屈光欠矫下使用C字视力表和E字视力表所测得的视力差别及探讨导致这种差别的原因。方法：选取不同年龄段250名受检者，在完全矫正屈光度[最正之最佳视力(maximum plus to maximum visual acuity，MPMVA)]情况下附加相应的球镜造成相应的近视度数后比较使用2种不同的视力表测出的视力值变化情况。同时根据2种视力表的设计原理及视力表的不同记录法探讨造成数值不同的可能原因。结果：同一附加度情况下分别用C字视力表组和E字视力表组行方差分析，不同年龄组间差异无统计学意义(P>0.05)。相同附加度情况下同一受检者使用C字视力表组和E字视力表组行t检验，两者差异具有统计学意义(t=?15.798，P<0.05)，C字视力表测得视力平均值小于E字视力表测得视力平均值。结论：受检者使用C字视力表比E字视力表检测视力结果更加优异；C字视力表和E字视力表的视标形状及开口方向不同是2种视力表检测结果差异的主要原因。
Objective: To compare the difference of visual acuity measured by C-chart and E-chart in the same myopic refractive undercorrection and to explore the causes of the difference. Methods: Two hundred and fifty subjects of different ages were selected to compare the changes of visual acuity measured by two different visual meters after adding corresponding spherical lenses to the maximum plus to maximum visual acuity (MPMVA) corrected diopter. At the same time, according to the design principle of the two kinds of visual acuity meters and the different recording methods of visual acuity tables, the possible reasons for the different values were discussed.Results: There was no significant difference between different age groups (P>0.05). Under the same degree of additionality, the visual acuity of the same subjects was tested by t-test with C visual acuity chart and E visual acuity chart. The difference was statistically significant (t=?15.798, P<0.05). The average visual acuity of C visual acuity table was smaller than that of E visual acuity table. Conclusion: The visual acuity of myopic patients tested by C visual acuity chart is better than by E visual acuity chart. The main reason for the difference between C visual chart and E visual chart was the different shape and opening direction of visual icons.

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 by dryness. 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.
