近年来日益强大的眼内液分子/细胞生物学检测技术因其简便、快捷和高效的特点，使得眼科医生在诊断眼内淋巴瘤时倾向于单纯只依据此类方法而淡化病理诊断的重要性。眼内液分子/细胞生物学技术因其本身只能“间接提示肿瘤细胞存在”的局限性而不能作为眼内淋巴瘤的确诊依据。眼内组织/细胞病理仍然是眼内淋巴瘤诊断的金标准，其价值和地位不能被其他任何分子/细胞生物学检测手段所替代。理解并掌握各种诊断、检测技术的优势和局限性，规范和优化眼内组织/细胞病理标本的采集、保存和送检流程有助于提高眼科临床医生对眼内淋巴瘤的诊断效率和医疗质量。

In recent years, more and more powerful molecular/cellular biological techniques of intraocular fluid have made ophthalmologists tend to only rely on these methods in the diagnosis of intraocular lymphoma because of their features of simplicity, fastness and efficiency. The molecular/cellular biological techniques of intraocular fluid cannot be used as the basis for the diagnosis of intraocular lymphoma because it can only indicate the existence of tumor cells indirectly. Intraocular tissue/cell pathology remains the gold standard for the diagnosis of intraocular lymphoma, and its importance cannot be replaced by any other molecular/cell biological methods. Understanding and mastering the advantages and limitations of various diagnostic techniques, standardizing and optimizing the collection, preservation and submission process of intraocular tissue/cell specimens will help ophthalmologists improve the diagnostic efficiency and medical quality of intraocular lymphoma.

黏膜相关淋巴组织(mucosa-associated lymphoid tissue lymphomas，MALT)淋巴瘤是原发性眼附属器淋巴瘤(primary ocular adnexal lymphoma，POAL)中最常见的病理类型。目前，原发性眼附属器黏膜相关淋巴组织淋巴瘤(primary ocular adnexal mucosa-associated lymphoid tissue lymphoma，POAML)的临床类型和临床表现尚未被眼科医师熟练掌握，临床治疗亦无共识和指南。本文根据POAML起源位置，重点介绍各临床类型的早中期临床表现，以及针对各临床类型和病变范围的个体化治疗方法。

Mucosa-associated lymphoid tissue lymphomas (MALT) lymphoma is the most common pathologic type in primary ocular adnexal lymphoma (POAL). Currently, the clinical types and manifestations of primary ocular adnexal mucosa-associated lymphoid tissue lymphoma (POAML) have not been well understood by ophthalmologists, and there is no consensus or guideline for clinical treatment. According to the original location, this paper focuses on the clinical manifestations of early and intermediate-stage POAML, as well as the individualized treatment for each clinical type and lesion range.

Objective: To investigate the clinicopathological and molecular genetics features of synovial sarcoma (SS) of the orbit. Methods: We retrospectively reviewed 10 published cases of primary SS of the orbit, along with 1 case of primary SS of the orbit confirmed by pathology who was admitted to the ophthalmology department of Eye & ENT Hospital of Fudan University in October 2020. The clinical data, radiological findings, morphology, immunophenotype and genetic characteristics of the cases were analyzed. Results: Our case was a 53-year-old woman with an SS in the right orbit, which had recurred multiple times. Histopathologic examination showed a primitive tumor composed of spindled and ovoid cells. Focal infiltration was observed in adjacent structures, such as the sub-conjunctiva, scleral surface, optic nerve sheath, muscle, and fibro-fatty tissue. Immunohistochemistry showed positivity for vimentin, calponin, CD99, and Bcl-2 and loss of INI-1expression, which is typical of SS. Fluorescence in situ hybridization (FISH) showed the (X;18) translocation in the tumor cells. The analysis included 2 males and 9 females aged between 1 and 53 years old (mean: 22 years; median: 24 years). Among the SS cases, 6 left eyes and 5 right eyes (all monocular cases) were affected. Symptoms had been present from 1 week to 13 years in the case from our hospital, while in 5 cases, symptoms had been present for at least 3 years. Common clinical features of the patients included proptosis or globe displacement, decreased vision, and pain. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed an ovoid mass with heterogenous enhancement and a cystic appearance, which was probably attributable to hemorrhage or necrosis. Of these 11 cases, 7 cases were biphasic SS, 4 were monophasic fibrous SS, and 2 were poorly differentiated in monophasic SS. Immunohistochemistry revealed positivity for pan-cytokeratin (CKpan), CK7, CK19, vimentin, cluster of differentiation 99 (CD99), B-cell lymphoma 2 (Bcl-2), calponin and transducin-like enhancer protein 1 (TLE1). Conclusion: Primary SS of the orbit is extremely rare and needs to be distinguished from other spindle cell tumors of orbital soft tissue. The SS diagnosis is based on the presence of the t(X;18) (p11; q11) translocation, which results in an SYT-SSX fusion gene.

目的：探讨眼囊尾蚴病的临床病理学特点。方法：回顾性分析7例眼囊尾蚴病的临床资料、大体与镜下病理改变。结果：男女性别比1:6，平均年龄24.7(中位数20)岁。临床以眼睑与眼周红肿、肿胀为主要症状3例，视物不清、视力下降2例，复视1例，结膜红肿1例。囊尾蚴寄生于球结膜1例，寄生于眼球内2例，寄生于眼眶内4例。7例均见到猪囊尾蚴，均在虫体内找到石灰小体，其中2例伴有坏死，可在坏死物中找到石灰小体。结论：眼囊尾蚴病以青少年女性多见，眼内型以视力下降为主要症状，眼眶型以眼睑与眼周红肿、肿胀为主要症状。找到囊尾蚴虫体与头节是眼囊尾蚴病明确诊断依据之一，石灰小体是该病重要病理诊断线索。

Objective: To explore the clinicopathological characteristics of ocular cysticercosis. Methods: The clinical data, grossing and microscopic pathological changes of 7 cases of ocular cysticercosis were analyzed retrospectively. Results: In this study, the male-to-female ratio was 1:6, the mean age was 24.7 (median age 20) years old. Of these patients, 3 patients presented with eyelid and periocular redness and swelling, 2 with blurred vision and decreased vision, 1 with diplopia, and 1 with conjunctival swelling and redness. In addition, 1 case was parasitized by cysticercus in the bulbar conjunctiva, 2 cases were in the eyeball and 4 cases were in the orbit. Cysticercus cellulosae containing calcareous corpuscle were observed in all cases, including 2 were accompanied by necroses with calcareous corpuscle. Conclusion: Ocular cysticercosis is found to be more common in female adolescents. Decreased vision is the main clinical symptom in intraocular infections, while orbital infections often show redness and swelling of eyelid and periocular. The finding of cysticercus and scolex in specimens is one of the confirmed diagnostic bases of ocular cysticercosis and calcareous corpuscles are important pathological diagnostic clues for this disease.

目的：比较重力液流与主控液流2种灌注方式下行白内障超声乳化手术对青光眼患者视盘血流的影响。方法：采用随机数字表法将患者分为2组，分别为重力液流灌注组和主控液流灌注组。记录术中超声乳化累积释放能量(cumulative dissipated energy，CDE)，术后1天、1周、1个月和3个月患者最佳矫正视力(best corrected visual acuity，BCVA)、眼压、视盘血流密度及视网膜神经纤维层厚度。结果：主控液流灌注组术中CDE小于重力液流灌注组(5.6±1.3 vs 6.3±1.2，P=0.034)。术后1天重力液流灌注组视盘周围血管密度(circumpapillary vascular density，cpVD)、整个图像血管密度(whole en face image vessel density，wiVD)和视盘内血管密度(inside disc vascular density，inside disc VD)均高于主控液流灌注组(P<0.05)，其余时间点差异无统计学意义(P>0.05)。术后1周和1个月重力液流灌注组视网膜神经纤维层厚度大于主控液流灌注组(P<0.05)，术后1天和3个月未见明显差异。结论：相较于传统的重力液流灌注，主控灌注能够在青光眼患者白内障超声乳化手术中减少超声能量的使用，术后早期可减轻由术中高眼压引起的视盘炎症性充血，可以减轻对视网膜神经纤维层的影响。

Objective: To compare the influence of active versus passive phacoemulsification fluidics systems on optic disc blood flow in patients with glaucoma. Methods: Patients were divided into 2 groups by a random number table method, namely the active fluidics system group and the passive fluidics system group. The intraoperative cumulative dissipated energy (CDE) was recorded, and the best corrected visual acuity (BCVA), intraocular pressure, optic disc blood flow density and retinal nerve fiber layer thickness were measured at the follow-up of 1 day, 1 week, 1 month and 3 months. Results: During phacoemulsification, CDE in the active fluidics system group was lower than that in the passive fluidics system group (5.6±1.3 vs. 6.3±1.2, P=0.034). One day after the surgery, the circumpapillary vessel density (cpVD), whole image vessel density (wiVD) and inside disc vascular density (inside disc VD) in the passive fluidics system group were higher than those in the active fluidics system group (P<0.05), and the differences were not statistically significant at the rest of the follow-ups (P>0.05).The retinal nerve fiber layer in passive fluidics system group was thicker than that in active fluidics system group at the follow-ups of 1 week and 1 month (P<0.05), and the difference was not statistically significant at the follow-up ofs 1 day and 3 months. Conclusion: Compared with the traditional passive fluidics system, the active fluidics system can reduce the CDE during phacoemulsification surgery. It can reduce the inflammatory congestion of the optic disc caused by intraoperative high intraocular pressure on the early postoperative stage. In addition, it can also protect retinal nerve fiber layer.

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.

Objective: To investigate the differences in bone destruction, nerve invasion, and prognosis of lacrimal gland adenoid cystic carcinoma (LGACC) among different histologic types and grades. Methods: A retrospective analysis was performed on 30 cases of lacrimal gland adenoid cystic carcinoma confirmed by histopathology who were admitted to the Department of Ophthalmic Oncology, Beijing Tongren Hospital, Capital Medical University from April 2010 to April 2019. The general data, imaging findings, histological examination and prognosis were collected and analyzed, with the focus on the relationship between the histological characteristics and the prognosis of lacrimal gland adenoid cystic carcinoma. Results: Among the 30 patients, 9 cases of cribriform type (30.0%); 10 cases of solid type (33.3%); 11 cases of mixed type (36.7%), including 4 cases of solid and glandular (13.3%), 4 cases of solid and cribriform (13.3%), 3 cases of cribriform and glandular (10.0%). The histopathological grade was I in 12 cases (40.0%), II in 4 cases (13.3%) and III in 14 cases (46.7%). There was statistical difference in the incidence of bone destruction among different histological types (P=0.046). There was no significant difference in the incidence of bone destruction among different histological grades (P=0.513). There was no significant difference between different histological grades and types and the incidence of nerve invasion and distant metastasis (all P>0.05). After surgery combined with radiotherapy, there was a statistical difference in the recurrence-free rate of different histological types, and the recurrence-free rate of solid type was the lowest within 36 months (P=0.037). Histological grade was not associated with recurrence-free rate after surgery combined with radiotherapy (P=0.059). Conclusion: The histological type of adenoid cystic carcinoma of lacrimal gland was significantly correlated with the incidence of bone destruction and recurrence rate, in which solid type was more likely to relapse. And the histological type was not associated with the incidence of nerve invasion or distant metastasis. Histopathological grade was not significantly associated with the rate of bone destruction, nerve invasion, distant metastasis, and recurrence.
