Objective: This study was designed to establish a mouse embryonic stem cell line that can drive GFP expression specifically in retinal ganglion cells (RGCs). Methods: In this study, we established a Brn3b-GFP knock-in embryonic stem cell line (Brn3b-GFP ESC) by homologous recombination. By 3D culture, we induced these cells into retinal organoids to investigate the cell-specificity of GFP expression. GFP-positive RGCs were then enriched by flow cytometry and transplanted by intravitreal injection into the eyes of healthy mice and NMDA injury model mice to explore the feasibility of a potential clinical application. Results: GFP was specifically expressed in RGCs following induction of Brn3b-GFP ESCs into 3D retinal organoids. Two weeks after these GFP-positive RGCs were transplanted into the control and injured mice, GFP-positive cells were observed in all transplanted retinas, and donor RGCs were seen to integrate into the RGC layer of the host retina. Conclusion: This study has established a retinal ganglion cell-specific reporter stem cell line Brn3b-GFP ESC. The GFP-positive RGCs obtained by inducing the cell line into retinal organoids can be integrated into the host retina after transplantation. The establishment of such a cell line will provide an important research tool for glaucoma and related diseases.
视网膜静脉阻塞(retinal vein occlusion,RVO)是发生率仅次于糖尿病性视网膜病变的视网膜血管病。RVO后导致视网膜血管损伤进而引起血管闭塞,造成视网膜缺血从而促进异常视网膜新生血管(retinal neovascularization,RNV)的增生,晚期发生玻璃体积血、新生血管性青光眼等并发症,积极治疗可以稳定患者的眼部情况,避免并发症的发生。本文报告了1例患有高血压病的23岁年轻女性患者发生视网膜分支静脉阻塞并发新生血管增殖膜的病例,给予病变区视网膜激光光凝治疗,10年后随访发现RNV膜机化萎缩。
Retinal vein occlusion (RVO) is the second most common retinal vascular disease after diabetic retinopathy. Retinal vascular damage after RVO leads to venous occlusion, which further causes retinal ischemia and promotes abnormal retinal neovascularization (RNV). Later complications such as vitreous hemorrhage and neovascular glaucoma occur. Active treatment can stabilize the ocular condition of patients and avoid the occurrence of complications. This paper reports a case of a 23-year-old young female patient with hypertension who developed branch RVO complicated by neovascularization membrane. The lesion area was treated with laser photocoagulation. The RNV was found to be mechanized and atrophied after 10 years of follow-up.
报道1例睫状体无色素上皮腺瘤(adenoma of nonpigmented ciliary epithelium,ANPCE)并进行相关文献复习。患者主要症状为左眼视力逐渐下降3个月,视物不清半个月。经眼部检查及左眼超声生物显微镜(ultrasound biomicroscopy,UBM)检查显示左眼虹膜周边隆起,边界清晰。予虹膜睫状体肿物切除术并行常规病理检查:光镜下肿瘤组织由分化好的上皮细胞组成,排列成腺泡状及条索状,细胞间可见红染无结构的基底膜样物;免疫组织化学表达:S-100(+)、Vimentin(+)、EMA(+)、CKpan(+)、Melan-A(+);最终病理诊断ANPCE。手术后截至随访日期,术后3个月无疾病进展。
A case of adenoma of nonpigmented ciliary epithelium (ANPCE) was reported and relevant literatures were reviewed. The left eye visual acuity of the patient gradually decreased for 3 months, and half a month was blurred vision. The vision examination and ultrasound biomicroscopy (UBM) from the left eye examination revealed a bulge in the peripheral iris in the left eye, with the boundaries are clear. The left eye was treated with ciliary mass resections and routine pathological examination: microscopy showed that the tumor tissue consists of well-differentiated epithelial cells, the tumor cells were arranged in tubes and cords, between the cells were seen red-stained unstructured basement membrane; immunohistochemistry showed: S-100 (+), Vimentin (+), EMA (+), CKpan (+), Melan-A (+); the final pathological diagnosis was ANPCE. There was no progression of the disease during the 3 months following the surgery on the follow-up date.
非器质性视力下降也称为心因性或功能性视力下降,除视力下降外,还可伴有视野缺损,多由于精神心理疾患导致的转换障碍引起,部分患者为诈病以获取利益。本文报道1例6岁的女性患者,主诉双眼反复视力下降1年余,早期被误诊为儿童视神经炎,给予糖皮质激素冲击治疗,治疗后稍有好转。通过本例患者误诊的教训,提醒我们在遇到儿童出现不明原因的视力下降时,在没有明确器质性疾病证据时要想到非器质性视力下降的可能,掌握识别非器质性视力下降的检查方法,不能忽略相对性传入性瞳孔障碍(relative afferent pupillary defect,RAPD)等基础的神经眼科检查。
Non-organic vision loss is also known as psychogenic or functional vision loss. In addition to vision loss, it can also be accompanied by visual field defect. It is mostly caused by conversion obstacles caused by mental and psychological diseases. Some patients cheat to obtain benefits. This paper reports a 6-year-old female patient who complained of repeated visual acuity decline for more than one year. She was misdiagnosed as pediatric optic neuritis in the early stage and was treated with glucocorticoid shock therapy, which her condition improved slightly after treatment. The misdiagnosis of this patient teaches us that when children have unexplained visual acuity decline, we should think of the possibility of non-organic visual acuity decline when there is no clear evidence of organic diseases, master the examination methods to identify non-organic visual acuity decline, and cannot ignore the basic neuro-ophthalmic examination such as relative afferent pupillary defect (RAPD).

Fungal keratitis is one of the important causes of corneal blindness in China. Due to the lack of reasonable treatment for some patients in the early stage of infection, the disease is protracted and refractory, and eventually, corneal transplantation is the main treatment. However, Fungal keratitis infection is very stubborn, and there is still a certain probability of recurrence after surgery. Therefore, understanding the latest research advances in fungal keratitis as well as the advantages and disadvantages of different types of antifungal drugs and corneal transplantation, and choosing a reasonable treatment plan according to the indications can maximize the control of the infection, reduce the recurrence rate of the fungus and save the vision of patients. In addition, the relevant literature on fungal recurrence after corneal transplantation was studied to summarize its recurrence pattern, influencing factors and clinical features, as well as treatment means and prognosis. The purpose of this study is to provide a reference basis for formulating a reasonable treatment strategy in line with China’s national conditions.
视神经脊髓炎相关性视神经炎(neuromyelitis optica spectrum disorder optic neuritis,NMO-ON)是一种常见的视神经炎(optic neuritis,ON)类型。女性非白种人占优势,损伤严重,双侧受累较多,视力预后差。我国有很大部分特发性ON最终诊断为NMO-ON。在相关实验室、光学相干断层扫描(optical coherence tomography,OCT)、磁共振(magnetic resonance imaging,MRI)等技术支持下,目前对NMO-ON的认识有了很大的进步,治疗方式除了皮质类固醇外还有免疫球蛋白、血浆置换及免疫抑制剂等。但提高NMO-ON的诊疗水平还有很长的路,更好地认识NMO-ON有助于更快速的诊断、更规范的治疗、更良好的预后。我们可以联合神经科开展多中心大样本量前瞻性的临床对照研究。
Neuromyelitis optica spectrum disorder- optic neuritis (NMO-ON) is a common type of optic neuritis (ON). This affliction is predominant in female non-Caucasians, with severe injury, more bilateral involvement, and poor visual prognosis. In China, a large proportion of idiopathic ON is ultimately diagnosed as NMO-ON. Our understanding of NMO-ON has made great progress under the technical support, such as the relevant laboratory, optical coherence tomography (OCT), magnetic resonance imaging (MRI). In addition to corticosteroids, immunoglobulin, plasmapheresis and immunosuppressive agents are also available for treatment. However, there is still a long way to improve the diagnosis and treatment level of NMO-ON. A better understanding of NMO-ON contributes to faster diagnosis, more standardized treatment, and better prognosis. We should cooperate with the neurology department to conduct a multi-center, large sample size prospective clinical control study.
近年来,由于经济社会不断发展,社会压力增大,人们精神障碍和干眼的发病率不断增加,这既影响人们身心健康,也给社会经济造成一定负担。大量研究表明精神障碍与干眼显著相关,精神障碍是干眼的独立危险因素之一。然而在临床工作中,精神障碍与干眼间的关系在过去一直未受到重视,本文将从精神障碍与干眼关联性入手,探讨其中介作用,总结了精神障碍因素影响干眼症状和体征分离,并进一步倡导跨学科综合管理来治疗干眼,形成对干眼的正确感知并降低疼痛及健康焦虑水平,以期为干眼临床诊疗提供新的视角。
In recent years, due to the continuous development of economy and society and the increasing social pressure, the incidence rate of mental disorders and dry eyes is increasing, which not only affects people’s physical and mental health, but also creates a certain burden on the social economy. A large number of studies have shown that mental disorder is significantly related to dry eye, and mental disorder is one of the independent risk factors of dry eye. However, in clinical work, the relationship between mental disorder and dry eye has not been paid attention in the past. This paper will start with the correlation between mental disorder and dry eye, explore the mediating effects, summarize the mental disorder factors that affect the separation of symptoms and signs of dry eye, and further advocate interdisciplinary comprehensive management to treat dry eye, form a correct perception of dry eye and reduce the level of pain and health anxiety, In order to provide a new perspective for clinical diagnosis and treatment of dry eye.

Objective: To assess whether cataract surgery can affect the progression of myopic foveoschisis, so as to provide evidence for the feasibility of cataract surgery to improve visual quality in patients with myopia foveoschisis accompanied by cataract. Methods: A total of 36 patients (36 eyes) diagnosed with high myopia foveoschisis at the Department of Ophthalmology, Shanghai Tenth People’s Hospital from April 2018 to January 2021 were enrolled in the study. The patients were divided into an experimental group (10 males with 10 eyes, and 8 females with 8 eyes) and an observation group (9 males with 9 eyes, and 9 females with 9 eyes) according to whether cataract surgery was performed. The central subfield thickness (CST), macular volume (MV), average macular thickness (AMT), best corrected visual acuity (BCVA), and the progression rate of foveoschis morphology were compared between the two groups at the initial diagnosis and 1 month, 3 months, 6 months, and 12 months after the surgery. Results: In terms of CST, MV, and AMT in the central macular area, no significant difference was found between the two groups (F=2.519, P=0.122; F=3.318, P=0.077; F=1.378, P=0.249), and there was no significant difference in time and group interaction effects between the two groups (F=0.825, P=0.370; F=1.266, P=0.268; F=0.612, P=0.657). In terms of BCVA, there was significant difference in time and group interaction effects between the two groups (P<0.001). The simple effect analysis showed that, compared with initial diagnosis, the BCVA in the experimental group was statistically significant at 1, 3, 6 and 12 months after the surgery (all P<0.001). In addition, there was a significant difference in the increments of BCVA between the two groups at 1, 3, 6, and 12 months after the surgery when compared with the initial diagnosis (all P<0.001). However, there was no significant difference in the morphological progression between the two groups (P=1.0). Conclusion: Phacoemulsification will not affect the progression of myopic foveoschisis in a short period, and can improve the vision of patients with myopic foveoschisis accompanied by cataract.
