目的：分析东莞市 498 例早产儿视网膜病变（retinopathy of prematurity，ROP）的筛查情况。方法：回顾性分析 2015 年 1 月至 2017 年 1 月在东莞市人民医院筛查的出生孕龄不足 34 周或体重不足 2 000 g 的早产儿，利用眼底筛查方法（RetCam II）对其视网膜病变进行筛查，对筛查结果进行概率分析。结果：早产儿的体重越轻，发生视网膜病变的可能性越大（χ² = 86.90，P < 0.0001）；早产儿的胎龄越小，发生视网膜病变的可能性越大，（χ² = 87.37，P < 0.0001）。结论：早产儿的体重、孕龄与其视网膜病变存在十分密切的关系，对于体重偏轻、孕龄偏低的早产儿应定期进行眼底筛查。

Objective: To analyze the screening of retinopathy of 498 premature infants in Dongguan City. Methods: RetCam II was used to screen the retinopathy of premature infants with less than 34 weeks gestational age or less than 2 000 g weight in our hospital from January 2015 to January 2017. Results: The lighter the body weight of premature infants, the more likely they were to develop retinopathy (χ²=86.90, P<0.0001), and the smaller the gestational age of premature infants, the more likely they were to develop retinopathy (χ²=87.37, P<0.0001). Conclusion: The weight and gestational age of premature infants are closely related to retinopathy, and fundus screening should be carried out regularly for premature infants with low weight and low gestational age.

目的：研究阿托品作用下豚鼠眼在不同单色光中的屈光发育情况。方法：24 只 2 周龄 3 色种豚鼠被随机分成 3 组，分别在蓝光（430 nm）、绿光（530 nm）和白光（色温 5000k）中饲养。3 组豚鼠的双眼从实验开始点 1% 阿托品滴眼液，1 次/d，持续 6 周。实验前后测量豚鼠屈光度和眼球生物参数。 结果：实验开始时 3 组各测量结果差异均无统计学意义。实验起始时各组平均屈光度约为 4.3 D。实验结束时白光组平均屈光度约为 4.84 D，绿光组约为 3.47 D，蓝光组约为 6.19 D，3 组间屈光度差异显著，且 3 组前后屈光度变化量比较差异显著。各组玻璃体腔长度在实验开始约为 3.3 mm，实验结束时白光组约为 3.25 mm，绿光组约为 3.39 mm，蓝光组约为 3.17 mm。此时白光组与绿光组玻璃体腔长度相比差异显著，绿光组与蓝光组相比差异显著，而白光组与蓝光组相比差异无统计学意义。实验结束时 3 组角膜曲率半径、前房深度和晶状体厚度无统计学差异。结论：阿托品通过干预豚鼠玻璃体腔长度的变化而影响单色光对屈光发育的作用，但单色光引起的屈光变化方向不受影响。

Objective: To investigate the effect of atropine on ocular refractive development of guinea pigs in different monochromatic lights. Methods: Twenty-four guinea pigs aged 2 weeks were randomly divided into three groups, which were raised in blue light (BL, 430 nm), green light (GL, 530 nm) and white light (WL, color temperature 5000k), respectively. The two eyes of the guinea pigs in the three groups were treated with 1% atropine eye drops once a day for 6 weeks from the beginning of the experiment. The refraction and ocular biological parameters of the guinea pigs were measured before and after the experiment. Results: At the beginning of the experiment,there was no significant difference in every measurement among the three groups. The average refraction of each group was about 4.3 D at the beginning. At the end of the experiment, the average refraction was approximately 4.84 D in the WL, 3.47 D in the GL, and 6.19 D in the BL. The differences in refraction of the three groups were significant, and the refractive changes of the three groups before and after the experiment were significant. The length of vitreous chamber in each group was approximately 3.3 mm at the beginning, but it was approximately 3.25 mm in the WL, 3.39 mm in the GL and 3.17 mm in the BL at the end of the experiment. At this time, there was significant vitreous difference between the WL and the GL, and between the GL and the BL, but there was no significant difference between the WL and the BL in vitreous length. After the experiment, there was no significant difference in the radius of corneal curvature, depth of anterior chamber and lens thickness among the three groups. Conclusion: The effect of monochromatic light on refractive development is affected by atropine through intervening the vitreous length in guinea pigs, but the direction of refractive change induced by monochromatic light is not influenced.

Objective: To evaluate the clinical efficacy of the combination of pan-macular grid laser, photodynamictherapy (PDT) and anti-vascular endothelial growth factor (VEGF) on a wide range of wet age-related macular degeneration (AMD), and to explore a more economical treatment method for wet AMD with low visual acuity. Methods: Patients with AMD with a range of lesions greater than 1.5 DD and visual acuity less than 0.3 were divided into the experimental group and the control group. In the experimental group, combined treatment was adopted, namely, a large choroidal neovascularization (CNV) lesion or multiple CNV lesions were treated by means of pan-macular grid laser directly in the outer area of the macular central arch, followed by the treatment of macular central lesions by PDT, and finally two to three days after the treatment of PDT, anti-VEGF drugs were injected into the vitreous cavity. In the control group (VEGF group), a standard 3+ prn anti-VEGF medication was administered. The changes in the visual acuity before and after the treatment were evaluated. Results: There were 27 cases in the experimental group, receiving (1.2±0.47) times of treatment on average, and 37 cases in the control received (3.4±1.9) times of treatment on average. Conclusion: The combined treatment can save the patient’s remaining vision and deserves widespread application, on the premise of significantly reducing the number of treatment.
