干眼是指以泪膜稳态失衡为主要特征并伴有眼部不适症状的多因素眼表疾病。目前干眼的主要治疗手段包括药物治疗(人工泪液替代疗法、抗炎治疗、免疫抑制治疗)和必要时的手术干预治疗。地夸磷索四钠属于P2Y2受体激动剂，是一种治疗干眼的新型药物。它通过刺激位于眼表组织的P2Y2受体，促进泪液、黏液、脂质分泌，增强泪膜稳定性，从而改善干眼的症状和体征。
Dry eye refers to a series of chronic and progressive ocular surface diseases characterized by imbalanced tear film accompanied with ocular discomfort symptoms. The available methods mainly include pharmacotherapy (artificial tears replacement, anti-inflammatory, immunosuppressive therapy) and ophthalmic surgery. P2Y2 receptor agonist is a novel pharmaceutical agent for dry eye treatment, which could stimulate tear fluid secretion and mucin secretion through binding with P2Y2 receptors on the ocular surface, so that improve tear film stability and alleviate symptoms of dry eye. 3% diquafosol ophthalmic solution is the only P2Y2 receptor agonist available for dry eye.
迟发性眼前节毒性综合征(toxic anterior segment syndrome，TASS)是TASS的一种特殊类型，两者既有共同点又有区别，随着人们认识的深入，越来越多的迟发性TASS被报道。迟发性TASS较典型性TASS少见，流行病学特征因人工晶体不同而有差异。几乎所有可引起典型性TASS的因素都可以引起迟发性TA SS，此外铝元素在迟发性TA SS的发生中可能有关键作用。迟发性TA SS临床表现与典型性TASS类似，累及后段更为常见，激素治疗有效。
Late-onset toxic anterior segment syndrome (TASS) is a special type of TASS, which has both similarities and differences. With the deepening understanding, more and more late-onset TASS is reported. Late-onset TASS is less common than typical TASS, and the epidemiological characteristics are vary with intraocular lenses. Almost all the factors that can cause typical TASS can cause late-onset TASS, in addition, aluminum element may play a key role in the occurrence of delayed TASS. The clinical manifestations of late-onset TASS are similar to those of typical TASS, with the involvement of the posterior segment more common and hormone therapy effective.

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.
