眼可受全身系统性疾病的累及，通过眼部表现可对心血管系统性疾病、神经系统疾病、自身免疫性疾病、感染性疾病及药物相关眼病等全身疾病进行评估、协助诊断和随访观察。重视全身疾病在眼部的表现，对于眼科及相关专业临床诊疗水平的提升具有重要意义。

Eyes can be affected by systemic diseases. Ocular manifestations can be used to evaluate, help to diagnose and observe systemic diseases including cardiovascular diseases, neurological disorders, autoimmune diseases, infectious diseases and drug-related eye diseases. Paying attention to the manifestations of systemic diseases in the eye is of great significance for the improvement of clinical diagnosis and treatment in ophthalmology and related specialties.

目的：探讨多发性大动脉炎的全身表现及眼部临床表现，提高眼科医生对大动脉炎的诊治能力。方法：采用回顾性病例系列研究。收集2018年3月至2022年5月山东第一医科大学附属省立医院风湿免疫科确诊后、经眼科会诊或治疗的大动脉炎患者14例，总结患者的全身表现、眼部临床表现及治疗结果。结果：14例多发性大动脉炎患者中，男性1例、女性13例，年龄(35.57±9.77)岁。其中，Ⅰ型头臂动脉型7例(50%)，Ⅱ型胸腹主动脉型2例(14.3%)，Ⅲ型肺动脉型0例，Ⅳ型广泛型5例(35.7%)。85.7%病例累及头臂动脉干。患者全身表现多样，最常见的是上肢低血压相关表现，4例发生严重的心脑血管并发症(28.6%)。5例(35.6%)患者以眼部症状为首发表现，3眼曾误诊为“白内障”(21.4%)。患者最佳矫正视力为无光感~1.0，其中，21眼最佳矫正视力为1.0(占75%)，4眼最佳矫正视力<0.1(占14.3%)。眼部检查正常者4眼(14.3%)，其余24眼(85.7%)均存在眼部异常。晶体异常、结膜巩膜血管扩张充血及瞳孔散大是最常见的眼前节表现。眼底表现以低灌注性视网膜病变为主(20眼，71.4%)，高血压视网膜病变4眼(14.3%)。与Ⅱ型患者比较，Ⅰ型患者更容易发生低灌注性视网膜病变。缺血导致的异常动静脉交通及视盘旁花冠状血管是最典型的眼底表现，严重者导致新生血管形成、增殖性玻璃体视网膜病变和视网膜脱离。所有患者经糖皮质激素和免疫抑制剂治疗，眼部行视网膜光凝及抗血管内皮生长因子(anti-vascular endothelial growth factor,anti-VEGF)药物治疗后，3眼视网膜病变仍有进展，其余患者病情稳定。结论：多发性大动脉炎是一种临床相对比较少见的慢性血管炎性阻塞性病变，年轻女性多发。本组病例以累及头臂动脉干为主，眼部受累概率高，缺血性眼前节表现是较容易被识别的体征，低灌注性视网膜病变是最典型的眼底表现，并可能引发严重的眼部并发症。眼科医生应提高对多发性大动脉炎的认识和诊断能力，并重视对大动脉炎患者的详细眼部检查。

Objective: To discuss the systemic and ocular manifestations of patients with multiplex Takayasu arteritis (TA) and improve the ability of ophthalmologists to diagnose and treat TA. Methods: Retrospective case series study was used. From March 2018 to May 2022, a total of 14 TA patients were admitted to the Department of Rheumatology and Ophthalmology in Shandong Provincial Hospital Affiliated to Shandong First Medical University. They were diagnosed by ophthalmology consultation and treated in the Department of Rheumatology and Immunology. Their systemic manifestations, ocular clinical manifestations, and treatment outcomes were summarized. Results: There were 13 female patients and 1 male patient in our TA cohot. Mean age was (35.57±9.77) years. The most common classification of TA was 7 cases of type I (50%). Others were type II (2 cases of Abdominal aorta and/or renal arteries involved, 14.3%) and 5 cases of type IV (combination of type I and type II, 35.7%), 0 cases of type III. The most common location of involvement was brachiocephalic arterial trunk (85.7%). TA patients had a variety of systemic manifestations, the most common was upper extremity hypotension-related manifestations. Severe cardiovascular and cerebrovascular complications occurred in 4 patients (28.6%). Ocular abnormal was the initial manifestation in 5 patients (35.6%), and 3 eyes were misdiagnosed as cataract (21.4%). Best corrected visual acuity (BCVA) of the TA patients was -1.0 with no light perception, among with 21 eyes had 1.0 (75%) and 4 eyes had a BCVA less than 0.1 (14.3%). Only 4 eyes were totally normal (14.3%) and the remaining 24 eyes (85.7%) had ocular abnormalities. Lens opacity, chronic scleral hyperemia and dilated pupil were the most frequent manifestations in ocular anterior segment. Fundus manifestations were dominated by hypoperfusion retinopathy (20 eyes, 71.4%) and 4 eyes suffered from hypertensive retinopathy (14.3%). Patients with Type I had a higher prevalence for developing hypoperfusion retinopathy than type II patients. Ischemia-induced fiscrete arteriovenous shunt and wreath-like anastomosis around the optic disc were the most typical fundus manifestations. Retinal neovascularization, proliferative vitreoretinopathy and retinal detachment were the most serious retinal complications. Corticosteroids and immunosuppressive agents were administered in all the patients. Most of the patients remained stable, while progression of retinopathy still could be seen in 3 eyes even after pan-retinal photocoagulation and intravitreal injection of anti-VEGF drug treatemnt. Conclusions: TA is a relatively rare chronic vasculitic obstructive lesion that occurs more often in young women. This group of cases mainly involved brachiocephalic artierial trunk. TA has a high possibility of ocular involvement and may lead to various ocular abnormalities. Anterior segment manifestations secondary to ischemia were the relative recognizable signal for diagnosis of TA. Hypoperfusion retinopathy was the most common fundus manifestations, and might cause serious ocular complications. Ophthalmologists should improve awareness and diagnostic capacity for multiple TA and value the detailed eye examination of TA patients.

Objective: To observe the clinical efficacy of medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe thyroid associated ophthalmopathy (TAO). Methods: A retrospective analysis was performed on 25 patients (31 eyes) with moderate-to-severe TAO from January 2020 to January 2022 in Eye Hospital of Zhejiang University, who were treated with medial-inferior wall orbital decompression combined with fat decompression. All of patients were given orbital computed tomography to measure visual acuity, exophthalmos, diplopia and ocular appearance before operation. The preoperative and postoperative exophthalmos, visual acuity and diplopia before and after operation were taken as efficacy evaluating indicators. The related data was counted and analyzed statistically. Results: After operation, the reduction of exophthalmos was 2-6 mm, with an average of (3.45±0.93) mm, the volume of intrazonal fat-removal was 1.4-3.6 mL, with an average of (2.33±0.66) mL, with a satisfactory appearance. There were 4 cases of preoperative diplopia and 2 cases of new diplopia after operation, all of which were mild diplopia. Diplopia did not exacerbate after operation in the patients who had diplopia before operation. Conclusion: Medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe TAO can effectively expand orbital volume, reduce exophthalmos, improve appearance with a concealed beautiful surgical incision, showing its good clinical efficacy.

Objective: To analyze the clinical characteristics of endogenous endophthalmitis caused by Klebsiella pneumoniae in diabetic patients, and summarize the treatment experience and evaluate its prognosis. Methods: A retrospective case analysis was performed on 7 patients (8 eyes) with endogenous endophthalmitis caused by Klebsiella pneumoniae, who were admitted to the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine from January 2019 to August 2022. The age, gender, origin of infection, time of treatment, visual acuity before and after treatment, intraocular pressure, slit lamp examination, fundus examination, ophthalmic B-mode ultrasound, treatment methods, infection control and recurrence were analyzed. Results: The mean age of the seven patients was (63±17.6). There were five males (71.4%) and 2 females (28.6%). Postoperative visual acuity was NLP in seven eyes (87.5%) and LogMAR visual acuity was 0.2 in one eye (12.5%). Visual acuity was related to the patient’s visit time and the visual acuity at visit. Six cases (85.7%) had fever before treatment. Fever was a risk factor for Klebsiella pneumoniae endophthalmitis infection. Eight eyes (100%) had mixed conjunctival congestion, and one eye (12.5%) had abscess in the anterior chamber. Seven eyes (87.5%) underwent vitrectomy combined with intravitreal drug injection, and one eye (12.5%) underwent intravitreal drug injection alone. Infections were controlled in all eight eyes without enucleation. Intraocular pressure was normal during the follow-up period, and there was no infection recurrence. Conclusions: Klebsiella pneumoniae is the main pathogen of endogenous endophthalmitis and is prone to occur in people with diabetes. The onset of the disease progresses rapidly. The early clinical manifestations are not typical, and the prognosis is closely related to the duration of the disease and the timing of treatment. Early treatment can restore some vision.

Objective: To measure the thickness of retinal ganglion cell layer and inner limiting membrane-retinal pigment epithelium layer in the macular region, and analyze its correlation with new-onset ischemic stroke. Methods: By using a prospective study, 30 healthy subjects (60 eyes) who underwent physical examination in Affiliated Hospital of Weifang Medical University from December 2021 to March 2022 were selected as the control group (Group A). Thirty age-matched patients with new-onset ischemic stroke admitted at the same time (60 eyes) were selected as the stroke group (Group B). The ganglioncelllayer (GCL) and innerlimitingmembrane-Retinalpigmentepithelium (ILM-RPE) were compared between the two groups. It included the thickness and mean GCL thickness/Mean Volume thickness of ILM-RPE (GCL/ILM-RPE thickness ratio). Results: A total of 120 eyes were included, with 60 eyes in group A and B. The average GCL thickness in group A was (83.5±4.7) μm, and the average GCL thickness in group B was (78.7±10.5) μm,and the difference between groups was statistically significant (P<0.001). The minimum thickness of GCL in group A was (80.4±4.4) μm, and the minimum thickness of GCL in group B was (70.7±16.3) μm, showing statistical significance(P<0.001). The thickness of the central subregion of ILM-RPE in group A was (247.5±19.8) μm, and the thickness of the central subregion of ILM-RPE in group B was (241.6±36.3) μm, and the difference was not statistically significant between two groups (P=0.393). The mean volumetric thickness of ILM-RPE in group A was (278.4±9.8) μm, and the mean volumetric thickness of ILM-RPE in group B was (278.5±15.3) μm, and the difference was not statistically significant (P=0.448). The GCL/ILM-RPE thickness ratio of group A was (0.300 3±0.012 2), and that of group B was (0.286 2±0.028 6), showing a statistical difference between groups (P<0.001). Conclusion: Ischemic stroke affects the GCL thickness and the thickness ratio of GCL/ILM-RPE, which may be related to new-onset ischemic stroke.

系统性红斑狼疮(systemic lupus erythematosus, SLE)是一类累及多种器官的结缔组织病，且SLE的发病机制十分复杂，常引起关节炎、脑病、肾病、皮肤损害，眼部病变亦是SLE常见疾病，且常引起视力障碍，甚至致盲、致残。该文通过整理文献，浅谈SLE相关眼病的类型、病因、眼部表现，以及SLE常用的中医辨证论治。

遗传在儿童和青少年的眼耳功能障碍发病机制中起着重要作用。由于眼耳有共同的神经内、外胚层起源，具有相似的基因网络，所以当共同的基因发生致病性变异时会导致眼耳双重感觉丧失。有超过70多种病因与聋盲有关，常见的伴有听力异常并累及视神经和视网膜的综合征型眼遗传病，包括CHARGE综合征、Usher综合征、Stickler综合征、Alport综合征、Wolfram综合征、Waardenburg综合征等。其他如染色体和胚胎的异常也会出现导致眼耳发育障碍，如Down综合征、Dandy-Walker综合征等。一些已知的眼遗传病致病基因变异也可导致听力异常，如OPA1基因。由于遗传异质性，眼耳综合征的临床诊断往往很困难，尤其是对婴幼儿。了解遗传综合征中眼耳相关临床特征，有利于早期发现和正确诊断；而当综合征中眼部表型不典型，可以通过耳部等其他系统表型协助诊断。同时，明确诊断对终生视觉和听觉功能的监测，以及与优生遗传咨询均有重要意义。

Heredity plays an important role in the pathogenesis of eye and ear dysfunction in children and adolescents. Because of common neural endodermal and ectodermal origins, the eyes and ears have the similar networks of genes Therefore, when pathogenic mutations occur in common genes, it can lead to loss of double sensation in the eyes and ears. There are more than 70 etiologies associated with the deafblindness, including CHARGE, Usher, Down, Stickler, Alport, Wolfram and Waardenbur syndromes, which are the most common syndromic ophthalmic genetic diseases with hearing and optic nerve/retinal abnormalities. Other abnormalities such as chromosomal and embryonic abnormalities can also lead to hearing and vision impairment, like Down and Dandy Walker syndromes. Some known genetic variants in ocular genetic diseases can also lead to hearing loss, such as OPA1 gene. Due to genetic heterogeneity, the clinical diagnosis of ocular and ear syndrome is often difficult, especially for infants and young children. With understanding the clinical features of eyes and ears in genetic syndrome,is conducive to early detection and accurate diagnosis, and when the ocular phenotype in the syndrome is atypical, it can be assisted by other systematic phenotypes such as the ear. At the same time, clear diagnosis is important for lifelong monitoring of visual and auditory function, as well as for eugenic genetic counseling.
