内源性真菌性眼内炎(endogenous fungal endophtalmitis, EFE)是最具破坏性的眼部感染之一，在临床上较少见。如诊断和治疗不及时，可严重损害患者视力，甚至需摘除眼球。由于EFE发病隐匿，病程较长，病原学涂片和培养阳性率较低，早期临床症状与葡萄膜炎相似，极易被误诊和漏诊，延误治疗时机。EFE最常见的感染灶来源为肝脏、肺、尿路、脑膜炎、胃肠道、心内膜以及骨髓。文章报道了一例腰椎感染致双眼内源性念珠菌性眼内炎的男性患者，66岁，因“右眼视力下降1周”首诊于眼科，专科检查见右眼玻璃体炎性混浊，初诊为右眼葡萄膜炎，予抗炎等治疗症状无好转，右眼视力持续下降，右眼前房穿刺抽液送检提示：热带念珠菌感染，之后左眼视力也逐渐下降，加之患者近期于骨科住院，术中腰椎间盘退变的纤维软骨组织DNA-病原微生物宏基因组检测结果示热带念珠菌，考虑双眼EFE，予全身及局部使用抗真菌药物联合双眼玻璃体切割手术，治疗后患者视力恢复良好，随访1年无复发。该病例及相关文献回顾，有助于加深临床医生对此类疾病的认识，为今后临床诊疗提供一定思路，也起到一定警示作用。
Fungal endophthalmitis is one of the most destructive eye infections and is relatively rare in clinical practice.If not diagnosed and treated promptly, it can severely damage vision and even lead to enucleation.Due to its insidious onset, long course, low positive rates in smears and cultures, and early clinical symptoms similar to uveitis, it is prone to misdiagnosis and missed diagnosis, leading to delayed treatment. A review of the literature indicates that the most common sources of EFE infection are the liver, lung, urinary tract, meningitis, gastrointestinal tract, endocarditis and osteomyelitis.In this paper, we report a case of lumbar spine infection causing bilateral candidal endophthalmitis in a 66-year-old male patient.He initially presented to the ophthalmology department of our hospital with a one-week history of decreased vision in the right eye, specialized examination revealed inflammatory opacity in the vitreous of the right eye, initially diagnosed as uveitis and treated with anti-inflammatory therapy without improvement.As the vision in the right eye continued to decline, aqueous humor aspiration from the anterior chamber of the right eye indicated infection with tropical Candida.Subsequently, the vision in the left eye also gradually decreased.Considering the recent hospitalization in the orthopedic department for lumbar disc degeneration, metagenomics analysis of fibrous cartilage tissue DNA during surgery detected tropical Candida, suggesting bilateral endogenous fungal endophthalmitis,The patient was treated with systemic and local antifungal medications in combination with bilateral vitrectomy surgery.After treatment, the vision recovered well, and there was no recurrence during a one-year follow-up.The objective of this thesis is to deepen the understanding of clinicians on this type of disease by reporting this case and reviewing relevant literature, providing some insights for future clinical diagnosis and treatment, and serving as a warning.
报告一例视神经脊髓炎谱系疾病(neuromyelitis optica spectrum disorders,NMOSD)合并人体免疫缺陷病毒(human immunodeficiency virus,HIV)感染/获得性免疫缺陷综合征(acquired immune deficiency syndrome,AIDS)，并通过文献复习，总结其发病机制、临床特征、治疗及预后。检索文献包括7篇英文文献(8个病例)，1篇中文文献，共报道9例NMOSD合并HIV感染/AIDS病例，结合本文报道的1例共10例，其中5例为女性，5例为男性，3例HIV感染/AIDS为新发，其他病例的HIV感染/AIDS发病均早于NMOSD。临床表现上，7例均为视神经炎和脊髓炎同时或相继发生，2例表现为单相病程或复发性脊髓炎，1例仅表现为双眼相继发生的视神经炎，10例患者头或脊髓MRI均有典型的视神经或脊髓异常信号，伴或不伴强化。2例患者未进行水通道蛋白4(aquaporin protein-4,AQP4)抗体IgG检测，其余8例中5例AQP4抗体阳性、3例阴性。针对AIDS的治疗，10例患者中，8例接受了高效抗逆转录病毒治疗(highly active antiretroviral therapy,HAART)。针对NMOSD的治疗，10例患者中，急性期有8例患者接受糖皮质激素冲击治疗、3例患者接受血浆置换、2例接受丙种球蛋白治疗，序贯治疗期有6例患者接受免疫抑制剂治疗，其中1例因高胆红素血症停药。发生视神经炎的7例中，2例患者经治疗仍失明、5例视力部分恢复，发生脊髓炎的8例中，5例患者遗留截瘫或轻瘫、3例肌力部分恢复。1例因严重并发症去世。NMOSD合并HIV感染/AIDS临床较罕见，预后差，往往遗留严重的视力障碍及瘫痪等，临床治疗较为棘手，糖皮质激素和免疫抑制剂并非使用禁忌证，但制定治疗决策前需要充分考虑风险与获益的平衡。
A case of neuromyelitis optica spectrum disorders(NMOSD) complicated with human immunodeficiency virus(HIV) infection/acquired immunodeficiency syndrome(AIDS) was reported, and the pathogenesis, clinical characteristics, treatment and prognosis were summarized through the literature review. The retrieved literatures included seven English literatures (eight cases) and one Chinese literature, in which a total of nine cases of NMOSD co-infected with HIV infection/AIDS were reported. Combined with the case reported in this paper, the total number of cases was ten, among which five cases were female and five cases were male, three cases of HIV infection/AIDS were newly developed, and the other cases had earlier onset of HIV infection/AIDS than NMOSD. In terms of clinical manifestations, seven cases all had simultaneous or sequential optic nerve and myelitis, two patients presented with a uniphasic course or recurrent myelitis, and one case presented only with bilateral optic neuritis occurring sequentially in both eyes. All ten patients had typical abnormal signals of the optic nerve or spinal cord with or without enhancement on cranial or spinal MRI. Two patients did not undergo AQP4 antibody IgG testing , and of the remaining seven cases, five were positive for AQP4 antibodies and three were negative. For AIDS treatment, eight of the ten patients received highly active antiretroviral therapy(HAART). For NMOSD treatment, among the ten patients, eight patients received intravenous methylprednisolone,three patients received plasmapheresis, and two patients received intravenous immunoglobulin in the acute phase. Six patients received immunosuppressive therapy during the sequential treatment period, and one of them was discontinued due to hyperbilirubinemia. Of the seven cases with optic neuritis, two patients remained blind after treatment and five had partial recovery of vision. Of the eight cases with myelitis, five patients were left with paraplegia or mild paralysis, and three had partial recovery of muscle strength. One case died due to serious complications.NMOSD combined with HIV infection/AIDS is rare in clinic and has a poor prognosis. Patients are often left with severe visual impairment and paralysis. Clinical treatment is quite difficult, hormones and immunosuppressive agents are not considered as contraindications. Treatment decisions need to be made with fully considered about the balance of risks and benefits.
目的：比较活体共聚焦显微镜和病理检查在角膜后部真菌感染的诊断阳性率，探讨两种检查方法在角膜后部真菌感染诊断中的价值。方法：回顾性病例对照研究。收集2009年11月至2020年12月在青岛眼科医院就诊并进行穿透性角膜移植手术治疗角膜后部真菌感染患者，术前均进行角膜刮片KOH涂片检查和活体共聚焦显微镜检查，术后病变角膜进行病理组织切片、过碘酸-Schiff法(PAS)染色和六亚甲基四胺银法(GMS)染色检查，比较不同检查方法诊断的阳性率。结果：18例角膜后部真菌感染患者角膜刮片KOH涂片均未检查到真菌菌丝，其中有16例患者经活体共聚焦显微镜检查到真菌菌丝(88.9%)，而2例患者在术前活体共聚焦显微镜检查中未查到病原体。术后病理检查PAS染色联合GMS染色，18例患者中18例均可检查到真菌菌丝，角膜后部真菌感染患者病理切片中可见角膜深基质层变性坏死，大量炎症细胞浸润，PAS染色和GMS染色可见典型真菌菌丝侵犯角膜基质深层，而角膜基质浅层及上皮层均未查见真菌菌丝。结论：活体共聚焦显微镜诊断角膜后部真菌感染具有一定的局限性，联合术后病理组织切片和特殊染色检查有助于提高角膜后部真菌感染的诊断率。
Objective: To compare the diagnostic rate between in vivo confocal microscopy and pathological examination in retrocorneal fungal infection. Methods: It is a retrospective study. A total of 18 patients with retrocorneal fungal infection and received PKP surgery in the Qingdao Eye Hospital from November 2009 to December 2020 were enrolled. KOH smear and in vivo confocal microscopy examination were performed before surgery, and pathological examination including periodic acid-schiff (PAS) stain and Grocott Methenamine Silver (GMS) stain were performed after surgery. Patients were diagnosed retrocorneal fungal infection based on in vivo confocal microscopy and pathological examination. The diagnostic rates of the two methods were compared. Results: None of the 18 patients with posterior corneal fungal infection were found to have fungal hyphae in the corneal smear.Sixteen patients (88.9%) were found fungal hyphae by in vivo confocal microscopy. Corneal stroma necrosis and a large number of inflammatory cells were shown by postoperative pathologic examination, and all patients were found fungal hyphae in posterior corneal stroma with PAS stain and GMS stain. Conclusion: Confocal microscopy has unique advantages such as non-invasive and rapid examination in the diagnosis of fungal keratitis.However, it needs to combine with pathological examination for diagnosing the retrocorneal fungal infection.

A case of human immunodeficiency virus (HIV) cytomegalovirus retinitis (CMVR) complicated with choroidal tuberculoma infection was reported. The patient visited hospital due to bilateral blurred vision for 2 weeks. Ocular examination showed extensive yellowish-white granular lesions in the temporal retina of the right fundus, with yellowish-white cheese-like exudation at the border of the lesion, and a large yellowish-white exudation with hemorrhage at the lower part of the left eye’s retina. After six months of follow-up, the patient was found to have a retinal choroid hump in the left eye. Based on her systemic and ocular clinical features, the patient was diagnosed as bilateral CMVR with choroidal tuberculoma of the left eye. The patient had her follow up check-up a year after her systemic antiviral and anti-tuberculosis treatment with her general condition stable and ocular lesions treated.
幽门螺杆菌(Helicobacter pylori，H P)感染是中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy，CSC)的一个危险因素，但是在HP感染和CSC相关性的研究仍存在争议，目前有两种观点：一是认为HP感染可能是CSC的一个危险因素，二是认为两者之间并没有相关性。本文将就对HP感染是否为CSC危险因素文献进行综述，同时探讨其发病机制。
Helicobacter pylori (HP) infection is a risk factor for central serous chorioretinopathy (CSC). But the existing studies tend to support two distinctively different trends regarding the link between HP infection and CSC. The first group tend to support that: HP infection may be a risk of CSC, and the second tend to claim to no correlation between the two. This paper will review the literature on whether HP infection is a risk factor for CSC and discuss its pathogenesis.
