  • 文章类型: Journal Article
    本研究的目的是使用多模态成像技术评估受I级和II级中央凹发育不全影响的一系列患者的遗传和表型数据之间的关系,这些患者具有稳定的固定和良好的视力。所有患者均接受完整的临床和仪器评估,包括结构光学相干断层扫描(OCT),OCT血管造影和自适应光学(AO)成像。中央黄斑厚度(CMT),内核层(INL),浅表毛细血管丛血管密度是OCT技术评估的主要变量.锥体密度,圆锥体间距,圆锥规律性,圆锥色散和角密度是用AO评估的参数。在所有受影响的个体中进行遗传评估和三外显子组测序。招募了8名患者(3名男性和5名女性),平均年龄为12.62岁(范围8-18)。平均最佳矫正视力(BCVA)为0.18±0.13logMAR,平均CMT为291.9±16.6µm,INL为26.2±4.6µm。通过对7例浅表毛细血管丛患者的OCT-A检查,证明了中央凹无血管区(FAZ)的缺失。然而,P5和P8患者的深神经丛存在部分FAZ。值得注意的是,所有患者的主要视网膜血管明显穿过中央凹中心。所有个体均表现为I级或II级中央凹发育不全。在5例患者中,分子分析显示,由TYR致病性变体和低形p的复合杂合性引起的白化病极为轻度。[Ser192Tyr;Arg402Gln]单倍型。一名患者患有由MITF的从头变异引起的2A型Waardenburg综合征。两名患者的分子分析不确定。所有患者在OCT-A上显示异常。根据目前的文献,光感受器计数与正常受试者没有差异,但AO成像的定性分析显示,这一部分个体的独特特征可能与异常色素分布有关.在中央凹发育不全的患者中,遗传和多模态成像数据,包括AO的调查结果,可以帮助了解中央凹发育不全表型的病理生理学。这项研究证实,尽管没有凹坑,但视锥密度和视觉功能都可以保留。
    Aim of the present study is to evaluate the relationship between genetic and phenotypic data in a series of patients affected by grade I and II of foveal hypoplasia with stable fixation and good visual acuity using multimodal imaging techniques. All patients underwent complete clinical and instrumental assessment including structural Optical Coherence Tomography (OCT), OCT Angiography and Adaptive Optics (AO) imaging. Central macular thickness (CMT), inner nuclear layer (INL), vessel density in superficial capillary plexus were the main variables evaluated with OCT technology. Cone density, cone spacing, cone regularity, cone dispersion and angular density were the parameters evaluated with AO. Genetic evaluation and trio exome sequencing were performed in all affected individuals. Eight patients (3 males and 5 females) with a mean age of 12.62 years (range 8-18) were enrolled. The mean best corrected visual acuity (BCVA) was 0.18 ± 0.13 logMAR, mean CMT was 291.9 ± 16.6 µm and INL was 26.2 ± 4.6 µm. The absence of a foveal avascular zone (FAZ) was documented by examination of OCT-A in seven patients in the superficial capillary plexus. However, there was a partial FAZ in the deep plexus in patients P5 and P8. Of note, all the patients presented with major retinal vessels clearly crossing the foveal center. All individuals exhibited a grade I or II of foveal hypoplasia. In 5 patients molecular analyses showed an extremely mild form of albinism caused by compound heterozygosity of a TYR pathogenic variant and the hypomorphic p.[Ser192Tyr;Arg402Gln] haplotype. One patient had Waardenburg syndrome type 2A caused by a de novo variant in MITF. Two patients had inconclusive molecular analyses. All the patients displayed abnormalities on OCT-A. Photoreceptor count did not differ from normal subjects according to the current literature, but qualitative analysis of AO imaging showed distinctive features likely related to an abnormal pigment distribution in this subset of individuals. In patients with foveal hypoplasia, genetic and multimodal imaging data, including AO findings, can help understand the physiopathology of the foveal hypoplasia phenotype. This study confirms that cone density and visual function can both be preserved despite the absence of a pit.

    一名84岁的男子表现出右眼视力下降。经过初步检查,右眼和左眼视力分别为0.03和1.2;此外,右眼和左眼眼压分别为12mmHg和13mmHg,分别。检查发现右眼前房浅,前房炎症,玻璃体混浊,和明显的视网膜脉络膜脱离.光学相干断层扫描(OCT)显示视网膜脱离(RD)和脉络膜褶皱;B超检查(B-scan)显示RD以及巩膜增厚,Tenon's间隙有液体。荧光眼底血管造影术显示视盘高度荧光,右眼血管通透性过高。左眼没有眼外症状或异常。右眼轴测量为23.4mm,由于位置变化,没有明显的视网膜下液迁移。因此,患者被诊断为与后巩膜炎相关的全葡萄膜炎,并立即开始使用40毫克泼尼松龙,改善了他的症状.然而,在治疗后3个月,观察到脉络膜皱褶,并在20mg泼尼松龙时重新开始。脉络膜褶皱随后消失了,右眼目前视力为0.3,无复发。我们的发现表明,通过B扫描和及时的全身类固醇给药可以准确诊断后巩膜炎。
    An 84-year-old man presented with decreased right-eye visual acuity. Upon initial examination, the rightand left-eye visual acuities were 0.03 and 1.2, respectively; moreover, the right- and left-eye intraocular pressure was 12 mmHg and 13 mmHg, respectively. Examination revealed a shallow anterior chamber of the right eye, anterior chamber inflammation, vitreous opacity, and marked retinochoroidal detachment. Optical coherence tomography (OCT) revealed retinal detachment (RD) and choroidal folds; moreover, B-scan ultrasonography (B-scan) showed RD as well as thickened sclera with fluid in Tenon\'s space. Fluorescent fundus angiography revealed hyperfluorescence in the optic disc and vascular hyperpermeability in the right eye. The left eye lacked extra-ocular symptoms or abnormalities. The right ocular axis measured 23.4 mm with no apparent subretinal fluid migration due to positional changes. Accordingly, the patient was diagnosed with panuveitis associated with posterior scleritis and immediately started on 40 mg prednisolone, which improved his symptoms. However, at 3 post-treatment months, choroidal folds were observed and was restarted on 20 mg prednisolone. The choroidal folds subsequently disappeared, with a current visual acuity of 0.3 in the right eye and no recurrence. Our findings indicated the utility of accurate diagnosis of posterior scleritis by B-scan and prompt systemic steroid administration.

    先天性单纯性视网膜色素上皮错构瘤(CSHRPE)是一种罕见的良性肿瘤,通常在常规眼科检查中偶然发现。我们介绍了一名32岁西班牙裔女性的多灶性CSHRPE病例,强调其呈现所带来的诊断挑战以及多模态成像在准确诊断中的关键作用。尽管最初由于外伤史和色素性眼底而遇到困难,先进的成像技术,包括光学相干断层扫描(OCT),OCT血管造影(OCTA),荧光素血管造影(FA),吲哚菁绿血管造影(ICGA),有助于精确诊断。值得注意的是,OCTA在最大的结节部位显示出高信号强度和流量,而FA和ICGA则表现出特征性的阻塞模式。此外,较小的结节显示OCT结果支持视网膜色素上皮(RPE)细胞岛在视网膜内异位增殖的理论.我们的病例强调了综合影像学评估在区分CSHRPE和其他病变中的重要性,有助于更深入地了解这种罕见的眼部疾病。
    Congenital simple hamartoma of the retinal pigment epithelium (CSHRPE) is a rare benign tumor often detected incidentally during routine eye exams. We present a case of multifocal CSHRPE in a 32-year-old Hispanic woman, emphasizing the diagnostic challenges posed by its presentation and the pivotal role of multimodal imaging in accurate diagnosis. Despite initial difficulties due to a history of trauma and pigmented fundus, advanced imaging techniques, including optical coherence tomography (OCT), OCT angiography (OCTA), fluorescein angiography (FA), and indocyanine green angiography (ICGA), facilitated a precise diagnosis. Notably, OCTA revealed high signal intensity and flow at the largest nodule site while FA and ICGA exhibited characteristic blockage patterns. Moreover, smaller nodules exhibited OCT findings supporting the theory of islands of retinal pigment epithelium (RPE) cells proliferating ectopically within the retina. Our case underscores the importance of comprehensive imaging assessment in distinguishing CSHRPE from other lesions, contributing to a deeper understanding of this rare ocular condition.

    背景:乳头周围超反射卵形团状结构(PHOMS)是新特征的病变,楔入视盘周围,以前被误诊了.更好地理解和识别PHOMS对于监测视神经状况很重要。
    方法:一位年轻女性出现双眼视力模糊的眼科诊所。发现了类似“C形甜甜圈”的突起,两侧环绕视盘。这些病变在OCT上是均匀的高反射,同时它们也是低自发荧光和低回声的。同时,两只眼睛也发现了黄斑囊样水肿(CME)。然后将患者诊断为具有CME的PHOMS。系统规定了短期糖皮质激素治疗。随着CME的恢复,双眼的logMAR最佳矫正视力(BCVA)在4个月内达到0.0,而PHOMS仍然存在。
    结论:目前没有关于PHOMS与CME的报告。应该更多地关注PHOMS,因为它们是与视神经不同疾病有关的轴质淤滞的潜在生物标志物。
    BACKGROUND: Peripapillary hyperreflective ovoid mass-like structures (PHOMS) are newly characterized lesions wedged around the optic discs, which used to be misdiagnosed. Better understanding and identifying PHOMS are important for monitoring the condition of optic nerve.
    METHODS: A young female presented to the ophthalmic clinic with blurred vision of both eyes. Protrusions resembling \"C-shaped donut\" were found circling the optic discs bilaterally. These lesions were homogenous hyperreflective on OCT, while they were also hypoautofluorescent and hypoechogenic. Meanwhile, cystoid macular edema (CME) was also identified in both eyes. The patient was then diagnosed as PHOMS with CME. A short-term glucocorticoids therapy was prescribed systemically. The logMAR best-corrected visual acuity (BCVA) of both eyes reached 0.0 in 4 months with recovery of CME, while the PHOMS remained.
    CONCLUSIONS: There is currently no report on PHOMS with CME. More attentions should be paid to PHOMS, for they are potential biomarkers for axoplasmic stasis involved in different diseases of the optic nerve.

    背景:报告一例女性患者在COVID-19感染后一个月出现多发性白点消失综合征(MEWDS),其年龄不寻常。
    方法:一名69岁的白人女性报告有漂浮物,验光,并在COVID-19感染后扩大了她的左眼视力丧失。临床和多模态成像与MEWDS诊断一致。荧光素血管造影检查显示,中央凹周围呈花环状的特征性高荧光斑点。广泛的实验室检查以排除其他自身免疫性和感染性病因尚无定论。一个疗程的皮质类固醇后,视力和白点消退,随访扩大眼底检查和多模态成像证实了这一点。
    结论:MEWDS是一种罕见的白点综合征,可能在COVID-19感染后发生,此外还有其他报告的眼科疾病。
    BACKGROUND: To report a case of Multiple Evanescent White Dot Syndrome (MEWDS) one month after a COVID-19 infection in a female patient at an age unusual for the occurrence of this disease.
    METHODS: A 69-year-old Caucasian female reported the presence of floaters, photopsia, and enlarging vision loss in her left eye following the COVID-19 infection. Clinical and multimodal imaging was consistent with the MEWDS diagnosis. Fluorescein angiography examination revealed characteristic hyperfluorescent spots around the fovea in a wreath-like pattern. An extensive lab workup to rule out other autoimmune and infectious etiologies was inconclusive. Visual acuity and white dots resolved after a course of corticosteroids, which was confirmed on follow-up dilated fundus exam and multimodal imaging.
    CONCLUSIONS: MEWDS is a rare white dot syndrome that may occur following COVID-19 infection in addition to other reported ophthalmic disorders following this infection.

    背景:黄斑视网膜裂孔(MRS)和近视黄斑新生血管(mMNV)都是高度近视的潜在致盲并发症。在这个案例报告中,我们强调了玻璃体内抗血管内皮生长因子(抗VEGF)治疗mMNV后MRS的进展,以及对有关该主题的文献的广泛评论。
    方法:一名49岁的女性近期出现了两周的右眼模糊和变形。她双眼高度近视(右眼-20/60与-16D,左眼-20/20与-13D)。裂隙灯检眼镜在双眼中发现正常的眼前段。眼底检查,双眼均观察到病理性近视伴后葡萄肿和乳头周围萎缩的特征。活跃的mMNV,以及视网膜内液体,最小中央凹内部和外部MRS,和沿着下颞区视网膜拱廊的局灶性玻璃体后部牵引,在右眼的光学相干断层扫描(OCT)上检测到。患者接受玻璃体内注射阿柏西普(2mg/0.05ml)。
    结果:两个月和四个月随访时的OCT扫描显示mMNV消退,视网膜前膜拉紧,外MRS逐渐恶化,以及位于中央凹下方的多个中央凹视网膜脱离的发展。在手术后的最后一个月就诊时,对进行性MRS进行了平坦部玻璃体切除术,具有良好的解剖学(已解决的MRS)和功能结果(维持视力为20/60)。
    结论:玻璃体内注射抗VEGF治疗mMNV可引起玻璃体视网膜界面改变,加剧MRS并导致视力下降。MRS的玻璃体切除术可能是几种治疗选择之一。
    BACKGROUND: Macular retinoschisis (MRS) and myopic macular neovascularization (mMNV) are both potentially blinding complications of high myopia. In this case report, we highlight the progression of MRS after intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment for mMNV, as well as an extensive review of the literature on this topic.
    METHODS: A 49-year-old woman presented with two weeks of recent onset blurring and metamorphopsia in her right eye. She had high myopia in both eyes (right eye - 20/60 with - 16D, left eye - 20/20 with - 13D). Slit-lamp ophthalmoscopy found a normal anterior segment in both eyes. On fundus examination, features of pathological myopia with posterior staphyloma and peripapillary atrophy were observed in both eyes. An active mMNV, as well as intraretinal fluid, minimal perifoveal inner and outer MRS, and focal posterior vitreous traction along the inferotemporal retinal arcade, were detected on optical coherence tomography (OCT) of the right eye. The patient received an intravitreal injection of Aflibercept (2 mg/0.05 ml).
    RESULTS: OCT scans at two- and four-month follow-up visits revealed regressed mMNV with a taut epiretinal membrane, progressive worsening of outer MRS, and the development of multiple perifoveal retinal detachment inferior to the fovea. Pars plana vitrectomy surgery was performed for the progressive MRS with good anatomical (resolved MRS) and functional outcome (maintained visual acuity at 20/60) at the last one-month post-surgery visit.
    CONCLUSIONS: Intravitreal anti-VEGF injections for mMNV can cause vitreoretinal interface changes, exacerbating MRS and causing visual deterioration. Vitrectomy for MRS could be one of several treatment options.

    眼底自发荧光(FAF)是一种快速且无创的成像方式,有助于检测视网膜和脉络膜内的病理异常。这篇叙述性综述和病例系列概述了FAF在后葡萄膜炎和全葡萄膜炎中的当前应用。文献回顾了有关特定后部和全葡萄膜炎实体的FAF病变特征以及FAF诊断和监测疾病的益处和局限性的文章。描述了非感染性和感染性葡萄膜炎形式以及伪装综合征的FAF特征。取决于葡萄膜炎实体,FAF在检测疾病和跟踪临床过程中具有诊断价值。激发波长不同的当前可用的FAF模式可以根据疾病实体和活动提供不同的病理见解。需要进一步研究FAF模式的比较及其对葡萄膜炎诊断和监测的个人价值。
    Fundus autofluorescence (FAF) is a prompt and non-invasive imaging modality helpful in detecting pathological abnormalities within the retina and the choroid. This narrative review and case series provides an overview on the current application of FAF in posterior and panuveitis. The literature was reviewed for articles on lesion characteristics on FAF of specific posterior and panuveitis entities as well as benefits and limitations of FAF for diagnosing and monitoring disease. FAF characteristics are described for non-infectious and infectious uveitis forms as well as masquerade syndromes. Dependent on the uveitis entity, FAF is of diagnostic value in detecting disease and following the clinical course. Currently available FAF modalities which differ in excitation wavelengths can provide different pathological insights depending on disease entity and activity. Further studies on the comparison of FAF modalities and their individual value for uveitis diagnosis and monitoring are warranted.

    This case report presents the diagnostic features of isolated primary intraocular lymphoma, which was initially misdiagnosed as neovascular age-related macular degeneration. A comprehensive examination using ultrasound, optical coherence tomography, and fundus autofluorescence revealed changes characteristic of vitreoretinal lymphoma. Molecular genetic analysis of the vitreous body showed the presence of a MYD88 gene mutation and B-cell clonality by immunoglobulin heavy chain (IGH) gene rearrangement tests, which confirmed the diagnosis.

    背景:报告一种罕见的脉络膜新生血管相关色素上皮病的发生是系统性红斑狼疮的首发表现。
    方法:一位54岁的女性,没有既往病史,由于右眼视力突然下降到20/80,因此寻求第二种意见。裂隙灯检查正常。眼底检查显示黄斑区存在视网膜下出血。包括光学相干断层扫描和荧光素血管造影在内的眼底成像显示与脉络膜新生血管(CNV)相关的多灶性视网膜色素上皮病变。患者在2周前接受了贝伐单抗的玻璃体内注射。决定通过两次额外的贝伐单抗注射来完成负荷剂量方案,第一次注射是在她的演讲后2周进行的。两周后,病人报告说她的脸颊上有皮疹,关节疼痛,还有紫癜.系统性检查显示ANA呈阳性,抗心磷脂抗体,补体水平下降,抗组蛋白抗体阴性。根据“系统性狼疮国际合作诊所”标准,这导致了系统性红斑狼疮(SLE)的诊断。患者用50mg泼尼松龙治疗,然后逐渐减少。第三次注射后1个月,显示视网膜下液的总分辨率,视力改善至20/20。随访期间未观察到复发。
    结论:根据眼底检查和影像学检查的结果,全身症状和血液检查,我们推测与脉络膜新生血管相关的色素上皮病与脉络膜水平的血管闭塞性疾病有关,脉络膜水平可能是SLE血管病变的一部分.据我们所知,这是首例以色素上皮病变和CNV为主要表现的SLE.
    BACKGROUND: To report a rare occurrence of pigment epitheliopathy associated with choroidal neovasculization as a first manifestation of systemic lupus erythematosus.
    METHODS: A 54-year-old female, with no prior medical history, sought a second opinion due to sudden drop in vision in her right eye to 20/80. Slit lamp examination was normal. Fundus examination revealed the presence of a subretinal hemorrhage in the macular area. Fundus imaging including optical coherence tomography and fluorescein angiography showed multifocal retinal pigment epitheliopathy associated with choroidal neovascularization (CNV). The patient had received an intravitreal injection of Bevacizumab 2 weeks ago. It was decided to complete the loading dose regimen with two additional Bevacizumab injections, and the first injection was done 2 weeks after her presentation. Two weeks later, the patient reported a rash on her cheeks, painful joints, and purpura. Systemic workup revealed positive ANA, anti-cardiolipin antibodies, and decreased complement levels, with negative anti-histone antibodies. This led to the diagnosis of systemic lupus erythematosus (SLE) based on the \"Systemic Lupus International Collaborating Clinics\" criteria. The patient was treated with 50 mg of prednisolone which was then tapered. 1 month after the third injection, an showed a total resolution of the sub-retinal fluid with an improvement of vision to 20/20. No recurrence was observed during follow-up.
    CONCLUSIONS: Based on the findings from the fundus exam and imaging, systemic symptoms and the blood work-up, we postulate that the pigment epitheliopathy associated with choroidal neovascularization was related to the vaso-occlusive disease at the level of the choroid that can be part of SLE vasculopathy. To our knowledge, this represents the first case in which pigment epitheliopathy and CNV were the primary manifestations of SLE.

    背景:报告1例视网膜中央动脉阻塞(CRAO),在玻璃体内注射布罗珠单抗治疗初治新生血管性年龄相关性黄斑变性(nAMD)患者后,无共同心血管疾病史。
    方法:一名79岁的亚洲男性,没有心血管疾病史,如糖尿病或高血压,每月连续3次玻璃体内注射布卢珠单抗,用于治疗左眼进展性nAMD。第三次注射两天后,患者出现急性无痛性视力丧失。在眼底照片上观察到典型的具有樱桃红色斑点的视网膜白化,在光学相干断层扫描(OCT)扫描中也发现了具有高反射率的视网膜肿胀.在荧光素眼底血管造影术上,臂至视网膜时间和动静脉通过时间明显延迟,但未观察到提示眼内炎症(IOI)的临床发现。因此,CRAO被诊断出来,并立即进行前房穿刺。然而,在三个月的随访期间,视力没有改善,尽管长期口服类固醇和抗血小板药物。
    结论:在极少数情况下,没有心血管合并症的患者在玻璃体内注射布卢珠单抗后可发生CRAO,而没有IOI的确证.因此,对于老年nAMD患者,玻璃体内注射布卢珠单抗后,应始终考虑CRAO,需要仔细观察。即使患者没有任何其他心血管疾病史。
    BACKGROUND: To report a case of central retinal artery occlusion (CRAO) after intravitreal injection of brolucizumab for a treatment-naïve neovascular age-related macular degeneration (nAMD) patient without comorbid cardiovascular disease history.
    METHODS: A 79-year-old Asian male without a cardiovascular disease history such as diabetes or hypertension underwent three times of monthly consecutive intravitreal brolucizumab injections for treatment of progressed nAMD in his left eye. Two days after the third injection, the patient presented with acute painless visual loss. Typical retinal whitening with a cherry red spot was observed on the fundus photograph, and retinal swelling with hyper-reflectivity was also identified on the optical coherence tomography (OCT) scan. On the fundus fluorescein angiography, arm-to-retina time and arteriovenous transit time were remarkedly delayed, but clinical findings suggesting an intraocular inflammation (IOI) were not observed. Therefore, CRAO was diagnosed, and anterior chamber paracentesis was administrated immediately. However, there had been no improvement in visual acuity during the follow-up period of three months, despite prolonged oral steroid and anti-platelet agent medication.
    CONCLUSIONS: In rare cases, patients without cardiovascular comorbidities can develop CRAO after intravitreal brolucizumab injection without gross evidence of IOI. Therefore, CRAO should always be in consideration and careful observation is required after intravitreal brolucizumab injection for nAMD patients with old age, even if the patient does not have any other cardiovascular disease history.
