    一名8个月大的女孩从她的儿科医生那里转诊,诊断为1型神经纤维瘤病(NF1),左眼角膜增大,面部左侧肿胀。她的左眼眼压(IOP)为21mmHg,角膜直径16毫米,外翻葡萄膜,杯:0.9的圆盘比,28.06毫米的轴向长度,和S形的上眼睑畸形。使用丝裂霉素C进行了未完成的联合小梁切开-小梁切除术。术后第1天,新的前房积血持续2周。进行了前房冲洗,显示出血的来源是沿着晶状体小带的持续的小扁豆膜。进行了Viscotamponade,角膜伤口闭合,眼张力略有升高。出血在接下来的5个月内没有复发,并控制IOP直至最后随访。
    An 8-month-old girl referred from her pediatrician with a diagnosis of neurofibromatosis type 1 (NF1) presented with an enlarged cloudy cornea of the left eye and a swollen left side of the face. Her left eye had intraocular pressure (IOP) of 21 mm Hg, corneal diameter of 16 mm, ectropion uvea, cup:disk ratio of 0.9, axial length of 28.06 mm, and S-shaped upper lid deformity. Uneventful combined trabeculotomy-trabeculectomy with mitomycin C was performed. On postoperative day 1, there was a new total hyphema that persisted for 2 weeks. An anterior chamber washout was performed, revealing the source of bleeding to be a persistent tunica vasculosa lentis along the zonules of the lens. Viscotamponade was performed, and the corneal wounds were closed, with the ocular tension slightly elevated. Bleeding did not recur for the following 5 months, and IOP was controlled until final follow-up.

    背景:迟发性囊阻滞综合征(CBS)是白内障超声乳化术和后房型人工晶状体(PCIOL)植入的一种罕见并发症,手术后六个月到几年。CBS的标志是在植入的人工晶状体(IOL)和后囊之间形成不透明的液体物质。然而,其发病机制尚不清楚。
    方法:1例64岁女性慢性闭角型青光眼(轴长<21mm)患者,行小梁切除术联合超声乳化和PCIOL。经过4年的随访,由于视轴中不透明液体的位置和囊袋的扩张,她的右眼视力下降。最初的行动过程是释放捕获的流体。由于她的瞳孔不扩张和后囊的高度延伸,无法采用钕:钇铝石榴石(Nd:YAG)激光囊切开术。随后,进行前囊剥离和前节玻璃体切除术。前房深度(ACD),后IOL表面和后囊之间的距离,最佳矫正视力(BCVA),手术前后测量视觉质量(VQ)。使用流式细胞仪评估PCIOL和后囊之间捕获的不透明物质(OS)中的炎性细胞因子水平,并与房水中的正常统计数据进行比较。手术后,患者经历了BCVA和VQ的显著改善.后IOL表面与后囊之间的距离濒临消失。然而,ACD在术前和术后之间没有差异。白细胞介素-8(IL-8)和碱性成纤维细胞生长因子(BFGF)在OS中的浓度高于房水,尤其是前者。然而,OS中血管细胞粘附分子(VCAM)的浓度低于房水。
    结论:前节段玻璃体切除术被证明是治疗迟发性CBS的成功方法,提出一个具有挑战性的案例。在人类的镜头中,来自不透明物质的炎性细胞因子可能导致密封区域的异常代谢,迟发性CBS的结果。
    BACKGROUND: Late-onset capsule block syndrome (CBS) is a rare complication of cataract phacoemulsification and the implantation of a posterior chamber intraocular lens (PCIOL), which manifests six months to years after surgery. The hallmark of CBS is the formation of an opaque liquid substance between the implanted intraocular lens (IOL) and the posterior capsule. However, its pathogenesis remains unclear.
    METHODS: A 64-year-old female patient with chronic angle-closure glaucoma (axis length < 21 mm) underwent trabeculectomy surgery combined with phacoemulsification and PCIOL. After a 4-year follow-up, a decline in visual acuity occurred in her right eye due to the location of opaque fluid in the visual axis and distension of the capsular bag. The initial course of action was to release the trapped fluid. Neodymium: yttrium-aluminum-garnet (Nd: YAG) laser capsulotomy could not be employed due to her non-dilating pupil and high extension of the posterior capsule. Subsequently, anterior capsule peeling and anterior segment vitrectomy surgery were performed. The depth of the anterior chamber (ACD), the distance between the face of the retro-IOL and the posterior capsule, the best-corrected visual acuity (BCVA), and the visual quality (VQ) were measured both before and after surgery. Inflammatory cytokine levels in the opaque substances (OS) trapped between the PCIOL and the posterior capsule were assessed using a flow cytometer and compared to normal statistical data in aqueous humor. After surgery, the patient experienced a significant improvement in BCVA and VQ. The distance between the face of the retro-IOL and the posterior capsule was on the verge of disappearing. However, ACD did not differ between pre- and post-operatively. Interleukin-8 (IL-8) and basic fibroblast growth factor (BFGF) concentrations were higher in the OS than in aqueous humor, especially in the former. However, the concentration of vascular cell adhesion molecule (VCAM) in the OS was lower than in aqueous humor.
    CONCLUSIONS: Anterior segment vitrectomy surgery proved to be a successful treatment for late-onset CBS, presenting a challenging case. In the human lens, inflammatory cytokines originating from the opaque substances may contribute to abnormal metabolism in the sealed area, a consequence of late-onset CBS.

    葡萄膜炎-青光眼-前房积血(UGH)综合征的特征是前房炎症发作,高眼压和前房积血。它是由虹膜或睫状体的机械磨损引起的,通常是由人工晶状体错位引起的。我们介绍了与插入Hydrus微支架有关的UGH综合征的罕见病例。由于正在进行的微创青光眼手术数量增加,并且与插入人工晶状体有关的UGH综合征患者减少,这是术后复发性炎症患者需要考虑的重要诊断。
    Uveitis-Glaucoma-Hyphema (UGH) syndrome is characterized by episodes of anterior chamber inflammation, elevated intraocular pressure and hyphema. It is caused by a mechanical chafing of the iris or ciliary body typically by a malpositioned intraocular lens. We present a rare case of UGH syndrome related to the insertion of a Hydrus Microstent. Because of the increased number of microinvasive glaucoma surgeries being performed and a reduction of UGH syndrome patients related to the insertion of intraocular lenses, it is an important diagnosis to consider in patients with recurrent postoperative inflammation.

    背景:多系统平滑肌功能障碍综合征(MSMDS)是一种影响多个器官的遗传疾病。这里的报告涉及一名MSMDS患者,到目前为止,他是所有报告的患者中最年轻的。除了典型的表现,我们观察到以前未报告的眼部异常,包括持续性血管前膜(TVL)和早发性视网膜小动脉迂曲,通过荧光素血管造影术(FA)。
    方法:患者出生后立即进入新生儿重症监护病房,诊断胎儿时期泌尿系统发育不良。经过彻底检查,患者被发现动脉导管未闭,肺动脉高压,脑血管疾病,低张性膀胱,肠旋转不良,和先天性散瞳。在她的6周内进行的眼睛FA显示,在持续的前TVL和突出的视网膜小动脉弯曲中灌注了脉管系统。整个外显子组测序揭示了从头杂合ACTA2基因错义突变p.R179H。
    方法:患者诊断为MSMDS。
    方法:随访观察。
    结果:在3个月的随访中,未观察到眼部疾病的变化。
    结论:在这种情况下,持续的前TVL意味着ACTA2p.R179H突变不仅影响平滑肌细胞,还影响周细胞,并进一步影响TVL回归。在这个6周大的婴儿中,突出的视网膜小动脉弯曲表明视网膜小动脉弯曲可以在MSMDS早期出现。
    BACKGROUND: Multisystemic smooth muscle dysfunction syndrome (MSMDS) is a genetic disease that affects multiple organs. The report here concerns a patient with MSMDS, who is known so far as the youngest among all the reported patients. In addition to the typical manifestations, we observed previously unreported ocular abnormalities, including persistent anterior tunica vasculosa lentis (TVL) and early-onset retinal arteriolar tortuosity, by the fluorescein angiography (FA).
    METHODS: The patient was admitted to the neonatal intensive care unit immediately after birth for a diagnosis of urinary system dysplasia during fetal life. After a thorough examination, the patient was found with patent ductus arteriosus, pulmonary hypertension, cerebrovascular disease, hypotonic bladder, intestinal malrotation, and congenital mydriasis. The FA of the eyes undertaken in her 6-week demonstrated perfused vasculature in the persistent anterior TVL and prominent retinal arteriolar tortuosity. The whole exome sequencing revealed a de novo heterozygous ACTA2 gene missense mutation p.R179H.
    METHODS: The patient was diagnosed with MSMDS.
    METHODS: Follow-up observation.
    RESULTS: At the 3-month follow-up, no change of the ocular disease was observed.
    CONCLUSIONS: The persistent anterior TVL in this case implies that ACTA2 p.R179H mutation affects not only the smooth muscle cells but also the pericytes, and further affects the TVL regression. The prominent retinal arteriolar tortuosity in this 6-week-old infant indicates that the retinal arteriolar tortuosity can present early in MSMDS.

    BACKGROUND: To report a case of lenticular infection caused by Aspergillus, which was diagnosed 13 weeks after traumatic corneal laceration.
    METHODS: A 60-year-old woman presented with traumatic corneal laceration including anterior lens capsule rupture and traumatic cataract after being hit with a chestnut in the right eye. There were multiple injuries due to tiny thorns of the chestnut, including the conjunctiva, sclera, cornea, and anterior lens capsule. But no visible foreign body was detected by slit-lamp examination. Topical corticosteroid was prescribed to resolve the conjunctival inflammation induced by the thorns of chestnut, which could have caused persistent irritation. As conjunctival injection and edema being decreased during outpatient clinical follow-up, embedded conjunctival foreign body was detected and surgically removed (1st surgery). Approximately 10 weeks after the trauma, severe inflammation of the anterior segment accompanied with hypopyon developed suddenly and at the same time embedded scleral foreign body was revealed. After removal of scleral foreign body (2nd surgery), unspecified mold species was cultured from the scleral foreign body in SDA (Sabouraud dextrose agar) plate. Suspicious corneal foreign body was removed as 3rd surgery and phacoemulsification of traumatic cataract was planned as 4th surgery. Aspergillus was finally detected from removed anterior capsule and fibrotic membrane during the operation. Fungal infection resolved successfully after administration of topical (1% voriconazole and 5% natamycin) and systemic (fluconazole) antifungal agents and phacoemulsification of traumatic cataract.
    CONCLUSIONS: Chestnut thorns can damage multiple ocular tissues simultaneously. Lens capsular rupture could result in fungal inoculation and lead to delayed lenticular fungal infection with complicated cataract formation. In cases of ocular trauma due to organic substances such as thorns and branches, the possibility of fungal infection should be considered.
