Objective: To evaluate the clinical safety and curative effect of phacoemulsification (Phaco) combined with multifocal intraocular lens (MIOLs) implantation in the treatment of senile cataract with 2.2 mm microincision cataract. Methods: The cataract patients who underwent phacoemulsification and intraocular lens implantation in our hospital were selected from January 1, 2018 to June 31, 2018. They were divided into two groups: group A with 31 patients (35 eyes) undergoing 2.2 mm micro-incision Phaco combined with MIOLs, while group B with 31 patients (38 eyes) undergoing 3.0 mm standard incision Phaco combined with single focus IOLs.The preoperative and postoperative uncorrected visual acuity, corneal curvature, intraocular pressure, corneal endothelium number, and defocus curve were recorded in both groups. The parameters during the operation were also recorded and compared. Results: There was no statistically significant difference in the parameters including total phacoemulsification time, total phacoemulsification energy, phacoemulsification cumulative energy compound parameters, effective phacoemulsification time, average phacoemulsification energy, total surgery time between group A and group B during the operation (all P>0.05). Compared with preoperative, the number of corneal endothelial cells decreased both in the two groups after surgery. The difference was statistically significant (P<0.05). There was no significant difference between the two groups at any time (all P>0.05). There were no complications such as posterior capsule rupture during operation in both groups. The corneal astigmatism was increased after operation both in the 2.2 mm incision and 3.0 mm incision, and the difference was statistically significant compared with pre-operation (both P<0.01). There was no significant difference between the two groups (all P>0.05). At 3 months postoperatively, there was no significant difference in uncorrected distance visual acuity (UCDVA) between the two groups (t=?1.794, P=0.07), and the difference was statistically significant in the uncorrected near visual acuity (UCNVA) (t=?25.147, P<0.01). Defocus curve: The defocus curve of group A had two peaks, which are located near 0 D and ?3.5 D, forming a flat platform with a descent between the two peaks.The defocus curve of group B had only one peak, located at 0–0.5 D, and the downward trend at both ends of the peak was obvious. The rate of off-glasses and satisfaction: the rate of off-glasses in group A was 77.42% (24/31),and the rate of dislocation in group B was 12.90% (4/31). The difference was statistically significant (χ2 =26.050,P<0.01). There was no significant difference in overall satisfaction between the two groups (χ2 =1.615, P=0.204).Conclusion: The 2.2 mm coaxial microincision cataract surgery yields high clinical safety, and the combined implantation of multi-focal intraocular lens has good curative effect and can be widely promoted in clinical practice.
目的：比较水合氯醛和阿佛丁两种药物对小鼠的麻醉作用以及不同激光能量对脉络膜新生血管造模成功率的影响。方法：24只C57/BL6小鼠随机分为3组，分别予以200，300和400 mW的532 nm激光进行视网膜光凝；每组再按1:1分为2个亚组，随机使用4.3%水合氯醛或1.2%阿佛丁进行小鼠腹腔注射麻醉。在激光光凝后第4，7，1 0和1 4天进行视网膜荧光素造影(Fundus Fluorescein Angiography，FFA)、SD-OCT检查，在第1 4天时对脉络膜行IB4染色检查。结果：阿佛丁和水合氯醛诱导小鼠进入麻醉时间长分别为(120±30) s和(150±45) s，持续时间分别为(30±15) min和(50±20) min，差异均有统计学意义(均P=0.0001)；发生不可逆性白内障的比率分别为2/24和1/24，麻醉导致的死亡数分别为1和0只，差异均无统计学意义(P =0.551，P =0.300)。200，300和400 mW三个激光能量组的造模成功率分别为9.38%，37.5%和93.75%，差异有统计学意义(P=0.0001)。FFA显示：造模成功的小鼠在4 d时荧光素渗漏达到高峰，随后荧光素溢漏的面积逐渐减小。结论：与阿佛丁相比，水合氯醛对小鼠的麻醉维持时间长且不会增加病死率和不可逆性白内障的发生率；400 mW的532 nm激光能量是诱发CNV的较好设置。
Objective: To compare the narcotic effects of chloral hydrate and avertin in mouse models and the success rate of choroidal neovascularization (CNV) mouse model establishment with different energy hierarchy of laser. Methods: Twenty-four mice were randomized into 3 groups, the 532 nm laser was used with different power levels of 200, 300 and 400 mW for each group. In each group, the chloral hydrate was used for 4 mice and avertin for the other 4 mice at random. On day 4, 7, 10 and 14, all mice were tested by the fundus fluorescein angiography (FFA), SD-OCT, and the choroid was stained with the isolectin B4 conjugated AF488 on day 14. Results: The anesthesia induction time of avertin and chloral hydrate was (120±30) s and (150±45) s, and the duration of anesthesia was (30±15) min and (50±20) min, the differences were statistically significant (all P=0.0001); the incidence of irreversible cataract of avertin models and chloral hydrate models was 2/24 and 1/24, the number of death in two models was 1 and without statistical significance (P=0.551, P=0.300). With the increase of laser energy, the success rate of experiments was also gradually increased, from 9.38%, 37.5% to 93.75% (P=0.0001) in 200, 300 and 400 mW group, respectively. According to the results of FFA, the peak of fluorescence leaking was at day 4 after the laser burning, and was gradually reduced. Conclusion: Compared with avertin chloral hydrate can improve the duration of anesthesia without increasing the risk of cataract and mortality. As for the 532 nm laser, the 400 mW energy could be an optimal parameter for the laser-induced CNV.
目的：研究调节抑制对不同单色光中豚鼠眼屈光发育的作用。方法：根据光照不同将豚鼠分成蓝光组(430 nm)、绿光组(530 nm)和白光组(色温5 000 K)，每组各8只。各组豚鼠右眼均点1%阿托品滴眼液，每天1次，持续6周。实验前后各测一次屈光度、角膜曲率半径以及眼轴各参数。结果：实验前各组豚鼠双侧眼间及组间同侧眼屈光度差异无统计学意义(约4.25 D，P >0.05)。但实验结束时蓝光组和绿光组双侧眼间屈光度差异显著(P=0.0003和P=0.028)，而白光组双侧眼间无显著差异(P=0.7486)。实验结束时各组左眼(P<0.05)、绿光组和白光组右眼(P=0.001)以及蓝光组和绿光组右眼(P <0.001)屈光差异有统计学意义。蓝光组和白光组右眼屈光差异无统计学意义( P =0.072)。实验开始时各组双侧眼间及各组间同侧眼玻璃体腔长度差异无统计学意义(约3.2 mm，P>0.05)。实验结束时，蓝光组和绿光组双侧眼间玻璃体腔长度差异有统计学意义(P=0.0017和P=0.0113)，但白光组双侧眼间差异无统计学意义(P=0.9371)。同时，各组间同侧眼玻璃体腔长度差异有统计学意义(P<0.01)。此外，实验前后各组双侧眼间及组间同侧眼角膜曲率半径、前节长度、晶状体厚度差异无统计学意义(P>0.05)。结论：1%阿托品加强530 nm单色光促进豚鼠眼玻璃体腔延长和近视形成的作用，但减弱430 nm单色光抑制豚鼠眼玻璃体腔延长和远视形成的作用。眼调节反应可能参与了单色光中豚鼠眼的屈光发育机制。阿托品影响单色光中豚鼠眼屈光发育的作用可能是通过抑制眼调节反应实现的。
Objective: To investigate the effect of inhibiting accommodation on ocular refractive development of guinea pigs in different monochromatic lights. Methods: Twenty-four pigmented guinea pigs were randomly divided into three groups with 8 animals per group: short-wavelength light (SL, 430 nm) group, middle-wavelength light (ML,530 nm) group and broad-band light (BL, 5 000 K color temperature) group. The right eyes of all animals were treated by 1% Atropine solution once a day for 6 weeks. Measurements of ocular refraction, corneal curvature, and axial length were performed at the start and the end of the study. Results: There was no significant difference in bilateral ocular refraction for all groups at the beginning of the experiment (about 4.25 D, P>0.05) and in ipsilateral ocular refraction among groups at the start of the experiment (P>0.05). But at the end of the experiment,significant differences were detected between binocular refraction of the ML group (P=0.028) and the SL group (P=0.0003), however, there was no significant difference between bilateral refraction in the BL group (P=0.7486).There were significant differences in refraction between the left eyes of any two groups (P<0.05), between the right eyes of the ML and BL group (P=0.001), and between the right eyes of the ML and SL (P<0.001) at 6 weeks.No significant refractive difference was detected between the right eyes of the SL and BL groups (P=0.072). The vitreous length was about 3.2 mm in bilateral eyes of all groups at the onset of the experiment (all inner- or inter-group P>0.05). After the experiment, the bilateral difference in vitreous length was significant in the ML group(P=0.0113) and the SL group (P=0.0017), but not significant in the BL group (P=0.9371). There were significant vitreous differences in right or left eyes among the groups at the end of the experiment (P<0.01). There were no significant inter-group (ipsilateral) or inner-group (bilateral) differences at any time in any of corneal radius of curvature, anterior segment length and lens thickness (P>0.05 for all comparisons). Conclusion: 1% atropine can strengthen the effect of vitreous elongation and myopic formation on guinea pig eyes in 530 nm monochromatic light. Moreover, atropine can weaken the effect of vitreous shortening and hyperopic formation on guinea pig eyes in 430 nm monochromatic light. Ocular accommodation response should involve in the mechanism of refractive development of guinea pig in monochromatic light. Atropine can influence the refractive development of guinea pig in monochromatic light possibly by inhibiting accommodation response.

睑板腺功能障碍(meibomian gland dysfunction，MGD)是眼科常见疾病，是蒸发过强型干眼的主要原因。基于人群流行病学的调查显示：MGD亚洲的发病率为46.2%~69.3%。目前，MGD治疗的方式包括眼睑清洁、热敷、睑板腺按摩、人工泪液、抗生素等，其中热敷为常用的家庭治疗方法。由于不同的热敷方式、温度、时间、频次及依从性，导致应用热敷治疗MGD到目前为止还没有统一标准。另外，热敷的不良反应如视物模糊、皮肤烫伤等，也没有引起临床足够重视。因此，为提高热敷的临床疗效及减少其不良反应，未来进行热敷的规范化指导或治疗很有必要。
Meibomian gland dysfunction (MGD) is a common ophthalmic disease, which is the main cause of evaporative dry eye. Population-based studies have suggested that the prevalence of MGD is high in Asia, with a reported incidence of 46.2% to 69.3%. Current modalities of MGD treatment include lid hygiene, warm compresses,massage, artificial lubricants, systemic and topical antibiotics, etc., among which warm compress is a common at-home treatment. Due to different eyelid warming methods, temperature, durations of heat application, frequency and compliance, there is no uniform standard for the application of warm compress to the treatment of MGD.In addition, adverse events of warm compress, such as blurred vision and thermal damage, have not attracted enough attention in clinical practice. Therefore, in order to improve the clinical efficacy of warm compress and reduce its adverse events, it is necessary to conduct standardized guidance or treatment of warm compress in the future. Based on the above considerations, this article will briefly review the application of warm compress to the treatment of MGD.
眼肌型重症肌无力(ocular myasthenia gravis，OMG)是一种累及神经肌肉接头突触后膜的自身免疫性疾病。OMG波动性的临床特征易导致较高的漏诊率和误诊率，严重影响患者的生活质量。因此，检测方法在早期确诊OMG中发挥重要作用。本文围绕临床检查、新斯的明试验、自身抗体检测、电生理检测等方面对OMG检测方法作一综述，以期为OMG的早期确诊提供有益的指导。
Ocular myasthenia gravis (OMG) is an autoimmune disease involving the postsynaptic membrane of the neuromuscular junction. The fluctuation of OMG and the clinical characteristics of fatigue easily lead to a high rate of missed diagnosis and misdiagnosis, which seriously affects the quality of life of patients. Therefore, detection methods play an important role in the early diagnosis of OMG. In this paper, OMG detection methods were reviewed in clinical examination, neostigmine test, autoantibody detection, electrophysiological detection, and other aspects, in order to provide useful guidance for the early diagnosis of OMG.

Objective: To explore the teaching effect of diagnosis and treatment on chalazion in the standardized training of ophthalmology residents and its existing problems, in order to improve the quality of the training systems. Methods: A self-designed questionnaire survey was conducted with 154 ophthalmology residents in Zhongshan Ophthalmic Center in April 2020, and the investigative data was analyzed using SPSS 20.0. Results: Totally 76 medical postgraduates and 78 ophthalmology residents completed the questionnaire survey. The proportions of medical postgraduates who had individual experience on diagnosis, conservative and surgical treatment of chalazion were 40.8%, 11.8%, and 7.9%. Compared to the former, ophthalmology residents had significantly higher proportion, with 79.5% (P<0.001), 60.3% (P<0.001), and 21.8% (P=0.016), respectively. For judging the important aspect of diagnosis and treatment process, the medical postgraduates chose the clinical diagnosis (90.8%) (P=0.007), while the ophthalmology residents paid more attention on treatment options (94.9%) (P<0.001). In the surgical procedures, removal of cyst wall, management of intraoperative accidents and skin ulcers are all their difficult skills to master for medical postgraduates (P<0.001), while only removal of cyst wall for residents (P<0.001). Conclusion: The training level of diagnosis and treatment of chalazion still needs to be improved in the standardized training of ophthalmology residents. The training should be carried out according to the clinical competence and cognition differences of various types of students.

Objective: To investigate and analyze the effect of He-Ne laser, recombinant human interferon α-2b ointment and gabapentin on skin lesion healing, sleep, pain and disease course in acute herpes zoster ophthalmicus. Methods: Sixty patients with acute herpes zoster ophthalmicus were collected from January 2017 to January 2020 in our hospital. According to the different treatment, they were divided into an experimental group (32 cases) and a control group (28 cases). The patients in the control group received routine basic treatment including antiviral, neurotrophic therapy, interferon α-2b ointment and gabapentin, and the experimental group was treated with He-Ne laser on the basis of control group treatment. The time of detumescence, blister stopping, scab formation, scab removal and pain relief, Visual Analogue Scale (VAS) score, sleep time, adverse reactions, and postherpetic neuralgia were collected and analyzed. Results: Before treatment, there was no significant difference in the observation indexes between the two groups (P>0.05); after treatment, the observation indexes of skin rash (detumescence, blister stopping, scab formation, scab removal) and pain relief time in the experimental group were significantly less than those in the control group, and the scab removal rate on the 4th and 7th days post-treatment in the experimental group was significantly higher than that in the control group; after treatment, the sleep duration was prolonged, and the VAS score was decreased. For pain relief and prolonging sleep time, the experimental group was better than the control group, and the difference was statistically significant P<0.05).There was no significant difference in scab removal rate on 2, 14 and 28 days post-treatment (P>0.05). The effective rate in the experimental group (93.75%) was significantly higher than that in the control group (75%), and the difference was statistically significant (P=0.047); there was no significant difference in PHN and adverse reactions between the two groups (P>0.05). Conclusion: He-Ne laser combined with interferon α-2b ointment and gabapentin is safe and effective in the treatment of acute herpes zoster ophthalmicus. It can significantly relieve the acute pain, promote the recovery of rash, improve sleep quality, shorten the disease course, and can be actively promoted in clinical usage.
