    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.

    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.

    交感神经眼炎是一种罕见且潜在破坏性的双侧弥漫性肉芽肿性葡萄膜炎。它是由手术或非手术眼外伤引起的,是一种罕见且严重的创伤并发症。它是临床诊断和支持的影像学检查,如眼超声和光学相干断层扫描。其治疗包括使用类固醇的免疫抑制治疗,有时还包括保留类固醇的药物。如环孢菌素,硫唑嘌呤,环磷酰胺,和霉酚酸酯。使用全身性免疫抑制剂进行快速有效的管理可以控制疾病并在交感神经眼中实现良好的视敏度。相比之下,只有在受伤的眼睛没有光感或存在严重创伤的情况下,才应考虑摘除。除了对该主题的书目审查之外,我们报告了6例涉及不同免疫抑制和手术治疗方式的病例。
    Sympathetic ophthalmia is a rare and potentially devastating bilateral diffuse granulomatous panuveitis. It is caused by surgical or non-surgical eye injuries and is an uncommon and serious complication of trauma. It is diagnosed clinically and supported by imaging examinations such as ocular ultrasonography and optical coherence tomography. Its treatment consists of immunosuppressive therapy with steroids and sometimes steroid-sparing drugs, such as cyclosporine, azathioprine, cyclophosphamide, and mycophenolate mofetil. Fast and effective management with systemic immunosuppressive agents allows for disease control and achievement of good visual acuity in the sympathizing eye. By contrast, enucleation should be considered only in situations where the injured eye has no light perception or in the presence of severe trauma. In addition to a bibliographic review of this topic, we report six cases involving different immunosuppressive and surgical treatment modalities.

    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.

Комплексное обследование с применением ультразвукового исследования, оптической когерентной томографии и аутофлуоресценции глазного дна позволило выявить изменения, характерные для витреоретинальной лимфомы. Молекулярно-генетическое исследование стекловидного тела показало наличие мутации гена MYD88 и B-клеточную клональность по генам тяжелой цепи IgH, что подтвердило диагноз.

    This article presents a case of a 31-year-old male patient who presented to the outpatient department of the Krasnov Research Institute of Eye Diseases with complaints of diplopia and increased intraocular pressure (IOP) up to 30 mm Hg. The patient had been using minoxidil topically for androgenic alopecia for 8 years. On examination, mild swelling of the bulbar conjunctiva in the upper fornix was revealed; optical coherence tomography showed thinning of the ganglion cell layer, most likely due to moderate myopia. The patient responded well to discontinuation of minoxidil and topical therapy with prostaglandin analogues. After 4 months, an attempt was made to replace topical hypotensive therapy with carbonic anhydrase inhibitors, but the previous hypotensive regimen had to be resumed due to an increase in IOP. During 10 months of observation, no signs of progression were detected according to optical coherence tomography and static perimetry.
    В статье представлен клинический случай пациента 31 года, который обратился в консультативно-поликлиническое отделение ФГБНУ «НИИ глазных болезней им. М.М. Краснова» с жалобами на диплопию, повышение уровня внутриглазного давления (ВГД) до 30 мм рт.ст. В течение 8 лет пациент использовал миноксидил местно по поводу андрогенной алопеции. При осмотре выявлена умеренная пастозность бульбарной конъюнктивы в верхнем своде; оптическая когерентная томография показала истончение слоя ганглиозных клеток, вероятнее всего, обусловленное миопией слабой степени. Пациент хорошо отреагировал на отмену миноксидила и местную терапию аналогами простагландинов. Спустя 4 мес предпринята попытка заменить местную гипотензивную терапию на ингибиторы карбоангидразы, однако из-за повышения уровня ВГД возобновлен прежний гипотензивный режим. В течение 10 мес наблюдения по данным оптической когерентной томографии и статической периметрии признаки прогрессирования не выявлены.

    虹膜的原发性间质囊肿很少见,通常无症状,偶然发现了实体。通常在增大或并发症的情况下需要治疗。然而,需要进行影像学检查以确定其囊性,并与恶性肿瘤进行准确的鉴别诊断,以及长期随访。超声生物显微镜是首选技术,尽管在大多数中心,眼前段光学相干断层扫描是一种更容易获得和可用的成像方式。我们介绍了一例虹膜原发性间质囊肿的非典型表现,以说明使用眼前节光学相干断层扫描和照片进行诊断和初步随访。和并发症的管理。前段光学相干断层扫描可能对可以完全看到囊肿的前段非色素病变的初步研究和随访有用。
    Primary stromal cysts of the iris are rare, often asymptomatic, and incidentally found entities. Treatment is usually indicated in cases of enlargement or complications. However, imaging tests are required to determine their cystic nature and make an accurate differential diagnosis with malignant tumors, as well as for long-term follow-up. Ultrasound biomicroscopy is the technique of choice, although in most centers anterior segment optical coherence tomography is a more accessible and available imaging modality. We present a case of primary stromal cyst of the iris with an atypical presentation to illustrate the diagnosis and initial follow-up using anterior segment optical coherence tomography and photographs, and the management of complications. Anterior segment optical coherence tomography may be useful in the initial study and follow-up of anterior non-pigmented lesions where the cyst can be fully seen.

    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.
