With the accelerated development of aging society, the incidence of glaucoma is increasing in recent years.Glaucoma is a primary cause of irreversible blindness worldwide and affects the visual and life quality of patients, which will bring great burden to the prevention and control of blindness in China. Terminology and Guidelines for Glaucoma formulated by European Glaucoma Society (EGS) is a classic document of Glaucoma guidelines.Recently, EGS released the Terminology and Guidelines for Glaucoma (5th edition), which put forward some updated concepts of diagnosis and therapy of glaucoma, primarily in several renewed key issues and the problems to be avoided in clinical practice.In the document, central corneal thickness is not recommended to correct intraocular pressure during the diagnosis and follow-up of glaucoma, and gonio-imaging devices do not replace gonioscopy in the diagnosis of angle-closure glaucoma, and optical coherence tomogranphy should not be used as the sole indicator in the early evaluation and dynamic monitoring of glaucoma.In addition, some available suggestions about anti-glaucoma drugs and surgeries are recommended for the managements of glaucomatous patients.The updated recommendations in the Terminology and Guidelines for Glaucoma (5th edition) are enunciated in this paper.

Somatostatin, also called somatotropin release-inhibiting factor (SRIF), is a kind of neurotransmitter, neuromodulator and neurotrophic factor, which participates in a variety of physiological functions in the central nervous system by activating the five G-protein-coupled receptors (sst 1-sst 5). SRIF and its receptors are extensively expressed and distributed in retina.Activation of SRIF receptors modulates voltage-gated K + and Ca 2+ channels, and regulates multiple intracellular signaling pathways in retinal cells, then influences neurotransmitter release and synaptic transmission, which plays an important role in the regulation of retinal visual information processing.In addition, SRIF and its receptors may provide protective effects against retinal injuries, such as retinal ischemia, excitotoxic injury and diabetic retinopathy.In this article, connected with related previous researches of our team, the distribution of SRIF and its receptor in retina, as well as the role of SRIF and its receptor in the physiological regulation and neuroprotection of retina were reviewed.

Using serological test to estimate the prevalence and infection potential of coronavirus disease 2019 in ocular diseases patients help understand the relationship between ocular diseases and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We conducted a cross-sectional study assaying the IgG and IgM antibodies in 1331 individuals with ocular diseases by using a magnetic chemiluminescence enzyme immunoassay kit, during the period from February 2020 to May 2020. In our study, the seroposivity in total ocular disease patients was 0.83% (11/1331). The patients with different ocular diseases including xerophthalmia, keratitis, conjunctival cyst, cataract, glaucoma, refractive error, strabismus and others had seroposivity of 2.94%, 12.5%, 25%, 4.41%, 2.63%, 1.6%, 2.22% and 0%, respectively. Among that, two ocular surface disease groups (keratitis and conjunctival cyst) had higher seroprevalence compared with others. All the participants were reverse transcription polymerase chain reaction negative for SARS-CoV-2 from throat swabs. Our study evaluated the seroprevalence in patients with different ocular diseases, which will help us understand the relationship between ocular disease and SARS-CoV-2 infection. Furthermore, the serological test for the presence of IgM and/or IgG antibodies against SARS-CoV-2 might provide accurate estimate of the prevalence of SARS-CoV-2 infection in patients with ocular diseases.

A few animals have been suspected to be intermediate hosts of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, a large-scale single-cell screening of SARS-CoV-2 target cells on a wide variety of animals is missing. Here, we constructed the single-cell atlas for 11 representative species in pets, livestock, poultry, and wildlife. Notably, the proportion of SARS-CoV-2 target cells in cat was found considerably higher than other species we investigated and SARS-CoV-2 target cells were detected in multiple cell types of domestic pig, implying the necessity to carefully evaluate the risk of cats during the current COVID-19 pandemic and keep pigs under surveillance for the possibility of becoming intermediate hosts in future coronavirus outbreak. Furthermore, we screened the expression patterns of receptors for 144 viruses, resulting in a comprehensive atlas of virus target cells. Taken together, our work provides a novel and fundamental strategy to screen virus target cells and susceptible species, based on single-cell transcriptomes we generated for domesticated animals and wildlife, which could function as a valuable resource for controlling current pandemics and serve as an early warning system for coping with future infectious disease threats.

COVID-19 virus has currently caused major outbreaks worldwide. ACE2 is a major cellular-entry receptor for the COVID-19 virus. Although ACE2 is known to be expressed in many organs, whether it is expressed by the conjunctival tissue is largely unknown. Human conjunctival tissues from 68 subjects were obtained, which included 10 subjects with conjunctival nevi, 20 subjects with conjunctivitis, 9 subjects with conjunctival papilloma, 16 subjects with conjunctival cyst, 7 subjects with conjunctival polyps, and 6 ocular traumas as normal subjects. Expression of ACE2 was evaluated by immunohistochemistry, immunofluorescence, reverse transcriptase-quantitative polymerase chain reaction, and western blot assay. We observed the expression of ACE2 by conjunctival tissues, expecially in conjunctival epithelial cells. ACE2 was significantly (p<0.001) overexpressed in conjunctival cells obtained from subjects with conjunctivitis, conjunctival nevi, conjunctival papilloma, conjunctival cyst, and conjunctival polyps epithelial cells when compared to that in conjunctival epithelial cells obtained from control subjects. Collectively, clinical features of reported COVID-19 patients combined with our results indicate that COVID-19 is likely to be transmitted through the conjunctiva.

Objective:To evaluate the clinical application of the SITA faster (SFR) visual field strategy in glaucoma patients.Methods:A diagnostic test was adopted.A total of 72 subjects who visited the Eye and ENT Hospital Affiliated to Fudan University during September 2018 to February 2019 were collected, including 28 normal subjects (56 eyes) and 44 glaucoma patients (86 eyes). The consistency and convenience of visual field tests were evaluated using SITA Standard (SS) and SITA Fast (SF), or SS and SITA Faster (SFR) in normal subjects and glaucoma patients.Test duration, visual field index (VFI), mean deviation (MD) and the number of defect points with probabilities of <5%, <2%, <1%, and <0.5% in the pattern deviation probability plots were recorded, and tested for difference, correlation and consistency.This study followed the Declaration of Helsinki.Written informed consent was obtained from all subjects prior to their entering the study cohort.The study protocol was approved by the Ethics Committee of the Eye and ENT Hospital of Fudan University.Results:For all of the included subjects, the mean test durations of SF and SFR were (64±13)% and (44±10)% compared to that of SS, respectively.MD and VFI evaluated by SS and SF, or by SS and SFR, showed no significant difference in either the normal subjects or the glaucoma patients (all at P>0.05). Across all included subjects, the positive correlation and consistency of MD and VFI were good ( r=0.99, P<0.01). However, for the results of the probability points in the pattern deviation probability blot, there was no difference among normal subjects, but the correlation and consistency were not good.In the deviation probability blot, there was a greater number of defect points of P<0.5% in glaucoma patients evaluated via SS compared to those evaluated by SFR, and the difference was statistically significant ( Z=-2.28, P=0.02). Apart from this, the number of defect points in glaucoma patients showed no difference between SS and SF, or between SS and SFR, and the correlation and consistency were higher in glaucoma patients than those in the normal subjects. Conclusions:Compared with SF and SS, SFR saves more test time.Except for partial variances in the pattern deviation probability blot, the difference between visual field strategies is relatively small and the results are basically consistent.

The pathogenesis and clinical manifestations of glaucoma in children are quite complex and diverse.Because the visual function of childhood is in a developing stage, even the intraocular pressure is controlled well, the visual function of childhood glaucoma patients is often poor from ametropia and amblyopia.So the prognosis is unsatisfying.New diagnostic classification of childhood glaucoma of the World Glaucoma Association showed that, except for glaucoma associated with acquired conditions and secondary glaucoma following cataract surgery, ocular anterior segment dysplasia in tissue structure and genetic factors are involved in the pathogenesis to different degrees in other classifications of childhood glaucoma.Therefore, it is very important for researchers to actively carry out genetic evaluation for childhood glaucoma.Current research status of molecular genetics in childhood glaucoma is briefly described here to emphasize that the researchers should make full use of available disease resources in China to carry out the study of molecular genetics in the diagnosis and classification of childhood glaucoma, which can provide more evidences for the prevention and treatment of blindness in children and healthy birth policy.

Reducing intraocular pressure is the only proven effective treatment of glaucoma.Drug therapy,laser and open surgery are the mainstay clinical tools to achieve this goal and surgical treatment has always been one of the most important method.In recent years,a variety of new methods of glaucoma surgeries were employed in clinical practice,which gave glaucoma surgeons more options.Minimally invasive glaucoma surgery (MIGS) is undoubtedly a topic of intense interest.In addition to new surgical procedures,many glaucoma treatment concepts have been updated.The role of lens extraction in the treatment of angle-closure glaucoma is another hot debate recently.For some classic glaucoma surgery,such as the well-known ciliary body destructive surgery used to treat for absolute glaucoma,has been found useful for early or mid-term glaucoma patients.It suggests that we need to reconsider these classic surgeries.Finally,Chinese ophthalmologists are facing special challenges of our own.Without the aid of mitomycin C (MMC),how to achieve good effects of filtering surgery is a conundrum for everyone.With the abovementioned numerous questions,how to choose a reasonable glaucoma surgery method has become the concern of glaucoma specialists.This article will discuss the development of glaucoma surgery as well as special issues in glaucoma surgery in China,aiming to illustrate the above mentioned questions.

<p><b>BACKGROUND</b>Lowering intraocular pressure (IOP) is currently the only therapeutic approach in primary open-angle glaucoma. and the fixed-combination medications are needed to achieve sufficiently low target IOP. A multicenter prospective study in the Chinese population was needed to confirm the safety and efficacy of Bimatoprost/Timolol Fixed Combination Eye Drop in China. In this study, we evaluated the safety and efficacy of Bimatoprost/Timolol Fixed Combination with concurrent administration of its components in Chinese patients with open-angle glaucoma or ocular hypertension.</p><p><b>METHODS</b>In this multicenter, randomized, double-masked, parallel controlled study, patients with open-angle glaucoma or ocular hypertension who were insufficiently responsive to monotherapy with either topical β-blockers or prostaglandin analogues were randomized to one of two active treatment groups in a 1:1 ratio at 11 Chinese ophthalmic departments. Bimatoprost/timolol fixed combination treatment was a fixed combination of 0.03% bimatoprost and 0.5% timolol (followed by vehicle for masking) once daily at 19:00 P.M. and concurrent treatment was 0.03% bimatoprost followed by 0.5% timolol once daily at 19:00 P.M. The primary efficacy variable was change from baseline in mean diurnal intraocular pressure (IOP) at week 4 visit in the intent-to-treat (ITT) population. Primary analysis evaluated the non-inferiority of bimatoprost/ timolol fixed combination to concurrent with respect to the primary variable using a confidence interval (CI) approach. Bimatoprost/timolol fixed combination was to be considered non-inferior to concurrent if the upper limit of the 95% CI for the between-treatment (bimatoprost/timolol fixed combination minus concurrent) difference was ≤ 1.5 mmHg. Adverse events were collected and slit-lamp examinations were performed to assess safety. Between-group comparisons of the incidence of adverse events were performed using the Pearson chi-square test or Fisher's exact test.</p><p><b>RESULTS</b>Of the enrolled 235 patients, 121 patients were randomized to receive bimatoprost/timolol fixed combination and, 114 patients were randomized to receive concurrent treatment. At baseline the mean value of mean diurnal IOP was (25.20 ± 3.06) mmHg in the bimatoprost/timolol fixed combination group and (24.87 ± 3.88) mmHg in the concurrent group. The difference between the treatment groups was not statistically significant. The mean change from baseline in mean diurnal IOP (± standard deviation) in the bimatoprost/timolol fixed combination group was (-9.38 ± 4.66) mmHg and it was (-8.93 ± 4.25) mmHg in the concurrent group (P < 0.01). The difference between the two treatment groups (bimatoprost/timolol fixed combination minus concurrent) in the change from baseline of mean diurnal IOP was -0.556 mmHg (95% CI: -1.68, 0.57, P = 0.330). The upper limit of the 95% CI was less than 1.5 mmHg, the predefined margin of non-inferiority. Adverse events occurred in 26.4% (32/121) of the bimatoprost/timolol fixed combination patients and 30.7% (35/114) of the concurrent patients. The most frequent adverse event was conjunctival hyperemia, which was reported as treatment related in 16.5% (20/121) in the bimatoprost/timolol fixed combination group and 18.4% (21/114) in the concurrent group (P > 0.05).</p><p><b>CONCLUSIONS</b>Bimatoprost/Timolol Fixed Combination administered in Chinese patients with open-angle glaucoma or ocular hypertension was not inferior to concurrent dosing with the individual components. Safety profiles were similar between the treatment groups.</p>

RÉSUMÉ
The management of open-angle glaucoma is a long-term,even lifelong procedure.A right medical decision can gain better efficacy and economic benefit and effectively avoid medical risk.Selective laser trabeculoplasty (SLT) is a therapy approved by FDA of USA and has been applied in China over decade.However,the clinical efficacy assessment is still controversial in China.For re-evaluation of the indication,methodology,technical parameters,and the efficacy of SLT will give full play to its advantage of the potential sufficient control of intraocular pressure (IOP) in glaucomatous treatment.The development of history,mechanism and effectiveness in control IOP,security and operation of SLT are reviewed.The suitable population,technique parameters,multiple centers clinical trial and the cost-effectiveness of SLT for Chinese glaucomatous patients are also proposed.
RÉSUMÉ
Background Selective laser trabeculoplasty (SLT) is a safe and effective therapy to the treatment of primary open angle glaucoma (POAG),and the clinical application is approved by American FDA.However,the relevant researching outcomes from several single-center study are in dispute owing to non-uniform approach in China.A muhicenter clinical trial is need to verify the effectiveness of SLT for Chinese POAG.Objective This study was to investigate the safety and efficacy of SLT in Chinese POAG patients.Methods A prospective,multicenter and self-controlled clinical trail was designed.Sixty-two eyes of 62 POAG patients with the age of ≥ 18 years were enrolled.Frequency SLT was performed around 360° angle using Lumenis Selecta DuetTM or Lumenis Selecta Ⅱ laser instrument,with the 100 non-overlapping spots,3 ns preset time,400 μm size of laser spot and 0.6 mJ energy.The operated eyes were followed-up for 6 months.The curative effects were checked including intraocular pressure (IOP),IOP-lowing value,number and percentage of IOP-lowing 20% and 30%.The therapyrelated complications were recorded including the number of conjunctival congestion and cloudy of the anterior chamber.Results The preoperative IOP was (25.7±2.6) mmHg in the 62 eyes.The IOP was significantly lowed 1 day,2 weeks,4 weeks,3 months and 6 months after SLT in comparison with preoperative IOP (all at P<0.001) with the lowest value of (16.5±4.5)mmHg in postoperative day 1.IOP was stable from 4 weeks to 6 months after operation.The mean lowing-value of IOP was 5.3-9.2 mmHg from 1 day through 6 months after SLT.The percentage of eyes 20% drop in lOP was 83.9%,and that of 30% drop was 58.1% in postoperative day 1.In 6 months after SLT,percentages of eyes 20% and 30% drop in IOP were 56.5% and 27.4%,respectively.Conclusions SLT is a safe and effective method of lowing IOP for POAG eyes in Chinese population.

Background Glucocorticoid drugs have been used increasingly in ophthalmology.It has been established that glucocorticoid are associated with a rise in intraocular pressure (IOP) and the development of glaucoma.Selective laser trabeculoplasty (SLT) is thought to be effective in treating patients with glucocorticoidinduced elevated IOP.Objective This study was to assess the efficacy of SLT in lowering IOP in patients with glucocorticoid-induced ocular hypertension.Methods A retrospective case series study was adopted.SLT around 360° chamber angle was performed in 9 eyes of 9 patients with glucocorticoid-induced glaucoma in Eye & ENT Hospital of Fudan University,including 5 eyes of 5 patients owing to use of glucocorticoid eye drops for long-term after laser in situ keratomileusis (LASIK) and 4 eyes of 4 patients who received intravitreal injection of 0.1 ml triamcinolone acetonide (TA) (4.0 mg) for macular edema induced by central retinal vein occlusion(CRVO).All of the patients were lack of preexisting glaucoma or ocular hypertension and underwent unsuccessful maximum tolerated medical therapy before SLT treatment.The base IOP was 35-44 mmHg and glucocorticoid drugs were ceased for 2-12 months prior to the SLT.The patients were followed-up for 6 months.IOP was measured and recorded before and 1 hour,1 week,1 month and 3 months,6 months after SLT.The difference of IOP was compared by repeated measures analysis of variance and multiple comparison analysis.Results All the patients received single SLT operation.The mean IOP was (40.0±2.9) mmHg before operation,but the IOP was (37.9±8.1),(34.9±5.9),(27.6±6.7),(21.6±6.9) and (17.9±2.9)mmHg 1 hour,1 week,1 month,3 months and 6 months after SLT.The IOP at 1 month,3 months and 6 months after SLT were significantly lower than that before operation (all at P<0.05).Two patients received a filtration surgery for uncontrolled IOP at 1 month and 3 months after SLT respectively,and another patient still used 2 kinds of lowing-IOP eye drops until the end of following-up duration.Conclusions SLT reduce IOP in 6 eyes of 9 patients with glucocorticoid-induced increased IOP from the initial 1 month through 6 months after SLT.
