目的：总结MAB21L2基因的变异和临床特点，并与高度同源的MAB21L1基因进行比较。 方法：对中山眼科中心临床基因数据库中MAB21L2基因变异患者进行基因型和表型分析，回顾性分析既往文献报道的MAB21L2基因和高度同源基因MAB21L1变异的表型-基因型的关系。结果：在2个小眼畸形家系中发现2个MAB21L2基因杂合变异：先证者1携带已知变异c.151C>G/p.(Arg51Gly)，患者双眼小眼畸形伴虹膜脉络膜缺损，伴骨关节屈曲。母亲携带相同杂合变异但表型正常；先证者2携带未报道的变异c.1042G>T/p.(Glu348*)，左眼小眼畸形，右眼正常且无全身异常。结合文献回顾发现，在显性遗传模式下，80%的MAB21L2杂合致病变异(20/25)和100%的MAB21L1杂合致病变异(25/25)发生在氨基酸49-52 区域，导致小眼无眼或眼缺损异常(microphthalmia, anophthalmia or coloboma,MAC)；携带该区域MAB21L2基因杂合突变的患者除MAC外，部分还伴骨骼关节发育异常(12/24，50%)；杂合截短变异发生在MAB21L2基因可导致MAC(5/5，100%)，而发生在MAB21L1则不致病。 结论：在2个小眼畸形家系中发现了MAB21L2基因1个新致病变异和1个已知热点致病变异，通过文献综述比较和总结了MAB21L1和MAB21L2基因的突变频谱以及基因型-表型相互关系，为此类基因缺陷导致遗传病的诊断和鉴别诊断提供依据。

Objective: To summarize the genetic variations and clinical features of the MAB21L2 and compare them with the highly homologous MAB21L1 gene. Methods: A genotype -genotype analysis was performed on the patients with MAB21L2 gene variants in the clinical genetic database of Zhongshan Ophthalmic Center, Sun Yat-sen University. A retrospective review was undertaken to analyze the phenotype-genotype correlations of MAB21L2 gene variants and the highly homologous MAB21L1 gene variants reported in the previous literature. Results: Two heterozygous MAB21L2 gene variants were identified in two families with microphthalmia: Proband 1 carried the known variant c.151C>G/p.(Arg51Gly), presenting with bilateral microphthalmia with iris-choroidal coloboma and flexion of joints. The mother carried the same heterozygous variant but had a normal phenotype. Proband 2 carried the unreported variant c.1042G>T/p.(Glu348*), manifesting as left-sided microphthalmia with a normal right eye and no other systemic abnormalities. Through literature review, we found that under a dominant inheritance pattern, 80% of heterozygous pathogenic MAB21L2 variants (20/25) and 100% of heterozygous pathogenic MAB21L1 variants (25/25) occurred in the amino acid region 49-52, resulting in microphthalmia, anophthalmia, and coloboma (MAC). Some patients with heterozygous MAB21L2 variants in this region exhibited additional skeletal and joint dysplasia (12/24, 50%). Heterozygous truncating variants in MAB21L2 led to MAC (5/5, 100%), while those in MAB21L1 were non-pathogenic. Conclusions: This study identified a novel pathogenic variant and a known hotspot pathogenic variant of MAB21L2 in two families with microphthalmia. Through a comprehensive literature review, we compared and summarized the mutation spectrums and genotype-phenotype correlations of MAB21L1 and MAB21L2 genes, providing valuable insights for the diagnosis and differential diagnosis of genetic diseases caused by these gene defects.

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段增大疾病，表现为大角膜(直径≥ 12.5 mm)、前房极深、角膜厚度正常或轻中度变薄和睫状环扩大等。并发性白内障以及晶状体脱位是导致AM视力下降的主要原因。然而，解剖结构的异常使AM白内障手术具有很大的挑战性。文章报道了一例AM合并白内障的48岁男性患者，成功为其行手法小切口白内障摘除联合人工晶状体(intraocular lens, IOL)一期植入术，患者术后视力恢复良好，IOL位置居中，未出现较大的屈光误差。对该典型AM病例的临床特点以及手术难点的回顾总结，有助于加深广大眼科临床工作者对该疾病的认识。

Anterior megalophthalmos is a rare congenital enlargement of the anterior segment, characterized by bilateral nonprogressive megalocornea (diameter ≥12.5 mm), extremely deep anterior chamber, normal or moderate thinning of the cornea, and elongation of the ciliary ring. Cataract and lens dislocation are the main causes of decreased vision in patients with AM. However, cataract surgery on patients with AM are challenging due to the anatomical abnormalities. This case reports a 48-year-old male patient diagnosed with AM and cataract, who successfully underwent a manual small incision cataract extraction combined with intraocular lens implantation. Finally, our patient showed a good visual outcome with a well centered IOL and without obvious refractive error. In this typical AM case, we reviewed and summarized the clinical characteristics and the challenges of surgical treatment so that other ophthalmologists can learn about this disease.

Objective: To demonstrate the clinical characteristics and surgical effects of glaucoma in Hallermann-Streiff syndrome(HSS). Methods: Observational case series and literature review. The results of ophthalmic examinations of three patients diagnosed as glaucoma with HSS were recorded, including visual acuity, intraocular pressure (IOP), slit-lamp microscopy, ultrasound biomicroscopy, optical coherence tomography, corneal topography, A-scan and B-scan ultrasonography, and orbital size measurement by X-ray. Peripheral iridectomy, glaucoma drainage device implantation or trabeculectomy, were performed in these patients. Results: Three HSS patients were 9, 29 and 47 years old, respectively, including 2 females and 1 male. The best corrected visual acuity was 0.04-0.5. The mean spherical equivalent refraction was +12.1 D. The average IOP was 37.7 mm Hg, and the average corneal diameter was 9.1 mm. The average central anterior chamber depth was 2.43mm. The average axial length was 18.13mm. Keratometry showed average K1 of 56.97 degrees, and K2 of 60.65 degrees. Two younger patients were aphakic bilaterally with uveitis, pupillary fibrous membrane and peripapillary choroidal atrophy. The older patient showed blue sclera, cataract, and anterior chamber angle closure. The horizontal orbital diameter was 28.76-31.40 mm, and vertical orbital diameter was 30.16-32.90 mm. All patients were proportionate nanism, with an average height of 143 cm. Craniofacial manifestations included dyscephalia and “bird-like” face, hypotrichosis, dental anomalies, and mandibular hypoplasia. They were followed up for an average of 47.7 months(range:11-84 months) after surgery. The IOPs were all controlled, and the visual acuities remained unchanged. No treatment-related complications occurred. Conclusions: HSS patients with glaucoma may present as small orbit, microphthalmia, microcornea, blue sclera, aphakia, pupillary fibrous membrane, uveitis, with atrophic chorioretinal changes. For these patients, personalized treatment may help to achieve better therapeutic effects.

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.

前段巨眼(anterior megalophthalmos, AM)是一种罕见的双侧非进展性先天性眼前段扩大疾病，表现为大角膜、角膜厚度正常或轻中度变薄、前房明显加深、睫状环扩大和悬韧带松弛。早期症状可仅表现为角膜散光和屈光不正等，并发性白内障和晶状体脱位是AM患者视力下降的主要原因。眼前段解剖结构的异常使AM患者的白内障手术具有很大的挑战性。首先，极端前房深度引起的有效晶状体位置(ELP)预测误差及公式选择不当是导致其术后较大屈光误差的主要原因；其次，悬韧带松弛易导致晶状体脱位、后囊膜破裂和玻璃体脱出等术中并发症的发生；由于超大囊袋及悬韧带松弛，人工晶状体(IOL)偏心甚至脱位也是术后常见的并发症。因此，需根据患者悬韧带情况、晶状体混浊程度采取合适的手术方式及谨慎选择IOL的类型。采用手法小切口晶状体囊外摘除术，可避免超声乳化的高灌注压对悬韧带的进一步损伤，增加手术的安全性；植入光学面及襻宽大的IOL术后具有较好的稳定性；新公式如Barrett Universal Ⅱ、Kane和EVO等公式具有较好的屈光预测准确性。然而，目前关于AM患者的白内障手术治疗报道仍属于个案报道，未来还需要更大样本量的临床研究进一步证实。
