    报告一例顽固性中央凹微动脉瘤(MA),通过使用新的外科手术成功治疗。
    这项研究涉及一名79岁的女性,她的左眼患有活跃的中央凹MA,并伴有视网膜分支静脉阻塞。尽管抗血管内皮生长因子治疗,MA在没有关闭的情况下保持活跃,最佳矫正视力(VA)从20/20逐渐下降到20/200。在向患者详细解释了我们的新外科手术后,从患者获得书面知情同意书,并进行了手术.简而言之,在平坦部玻璃体切除术后,剥离她左眼的内界膜,然后轻轻切开MA外壁的视网膜。然后直接抓住暴露的MA并用27号微镊子拉到视网膜上,并进行光凝。术后3个月,观察到MA的闭合和视网膜发现的改善,最佳校正VA改善至20/67。
    我们报告了一例难治性中央凹MA,该病例通过一种新的闭合MA的手术技术成功治疗,避免对周围组织的热损伤,并导致术后VA改善。
    UNASSIGNED: To report a case of a refractory foveal microaneurysm (MA) that was successfully treated by use of a new surgical procedure.
    UNASSIGNED: This study involved a 79-year-old female with an active foveal MA associated with branch retinal vein occlusion in her left eye. Despite anti-vascular endothelial growth factor treatments, the MA remained active without closure, and best-corrected visual acuity (VA) gradually decreased from 20/20 to 20/200. After our new surgical procedure was explained in detail to the patient, written informed consent was obtained from the patient and the surgery was performed. Briefly, following pars plana vitrectomy, the internal limiting membrane in her left eye was peeled and the retina of the external wall of the MA was then gently incised. The exposed MA was then directly grabbed and pulled up onto the retina using 27-gauge microforceps, and photocoagulation was performed. At 3-months postoperative, closure of the MA and improvement in the retinal findings were observed, and best-corrected VA improved to 20/67.
    UNASSIGNED: We report a case of a refractory foveal MA that was successfully treated with a novel surgical technique that closed the MA, avoided thermal damage to the surrounding tissue, and resulted in improved postoperative VA.

    Terson综合征是指由于与颅内压急性升高相关的蛛网膜下腔出血而发生的眼内出血。以前没有研究报道继发于Terson综合征的延迟性黄斑裂孔(MH)。一个17岁的男孩来了我们的部门,并出现了玻璃体出血和蛛网膜下腔出血的病史。在平坦部玻璃体切除术中检测到亚内界膜(ILM)出血,ILM脱离和视网膜内出血。此外,术后1周发现延迟MH.在2个月的随访中没有MH关闭的迹象。随后,进行MH按摩以关闭MH。我们的发现表明,延迟的MH可继发于Terson综合征。升高的动水压力和静水压力,这是由亚ILM和视网膜窝出血引起的,有助于MH的形成。此外,ILM剥离可能导致黄斑损伤并促进MHs的形成。尽管MH可能会自行关闭,当没有迹象表明MH会自发关闭时,建议进行早期手术干预,因为MH时间延长会导致视网膜损伤.
    Terson syndrome refers to intraocular haemorrhage that occurs due to subarachnoid bleeding associated with an acute increase in intracranial pressure. No previous study has reported a delayed macular hole (MH) secondary to Terson syndrome. A 17-year-old boy visited our department and presented with vitreous bleeding and a history of subarachnoid haemorrhage. Sub-internal limiting membrane (ILM) haemorrhage with ILM detachment and intraretinal haemorrhage were detected during pars plana vitrectomy. Additionally, a delayed MH was detected 1 week after the surgery. There was no sign of MH closure during a 2-month follow-up. Subsequently, an MH massage was performed to close the MH. Our findings suggest that a delayed MH can occur secondary to Terson syndrome. Elevated hydrodynamic pressure and hydrostatic pressure, which are caused by sub-ILM and intraretinal haemorrhages of the fovea, contribute to the formation of an MH. Additionally, ILM peeling may cause damage to the macula and facilitate the formation of MHs. Although the MH may close by itself, early surgical intervention is recommended when there is no sign that the MH will close spontaneously because a prolonged MH can lead to retinal damage.

    UNASSIGNED: RS3PE (remitting seronegative symmetrical synovitis with edema and pitting) is a rare entity of unknown etiology that has been related to genetic predisposition due to the presence of HLA-A2 in 50% of cases and less frequently HLA-B7. Its pathogenesis is unknown, but it has been related to growth factors, and some mediators (TNF, IL-6). It is common in elderly people and the course of this illness presents with acute symmetrical polyarthritis, accompanied by edema in hands and feet. The diagnosis requires a high index of suspicion and to differentiate it from other entities such as rheumatoid arthritis, complex regional pain syndrome, rheumatic polymyalgia, in addition to ruling out malignant neoplasms, since there are many reports of its association with both solid and hematological neoplasms, being of bad prognosis when there is association. When there is no association with cancer, it responds well to the use of low doses of steroids and its prognosis is usually favorable.
    UNASSIGNED: 80-year-old woman with an acute onset with polyarthralgia, functional limitation associated with pitting edema in hands and feet. After approaching the patient and ruling out associated neoplasms, it was diagnosed RS3PE. It was managed with prednisone, observing a good response, with remission of the manifestations at 6 weeks and subsequent suspension of the steroid.
    UNASSIGNED: RS3PE is a rare entity, and a high index of suspicion is required for the diagnosis. A complete approach is important to rule out cancer in patients affected with this syndrome. Prednisone continues to be the best therapeutic option.
    UNASSIGNED: la RS3PE (sinovitis simétrica seronegativa remitente con edema y fóvea) es una entidad rara de etiología desconocida que se ha relacionado con predisposición genética por la presencia de HLA-A2 en el 50% de los casos y con menor frecuencia HLA-B7. Se desconoce su patogenia, pero se ha relacionado con factores de crecimiento y algunos mediadores (TNF, IL-6). Se presenta en personas de edad avanzada, cursa con poliartritis aguda simétrica, acompañada de edema en manos y pies. El diagnóstico requiere de un alto índice de sospecha y diferenciarlo de otras entidades como artritis reumatoide, síndrome de dolor regional complejo, polimialgia reumática, además de descartar neoplasias malignas, ya que existen muchos reportes de su asociación con neoplasias tanto sólidas como hematológicas y es de mal pronóstico cuando existe asociación. Cuando no existe asociación con cáncer tiene buena respuesta al uso de dosis bajas de esteroides y su pronóstico suele ser favorable.
    UNASSIGNED: mujer de 80 años con un cuadro de inicio agudo con poliartralgias, limitación funcional asociada a edema de manos y pies con fóvea. Después del abordaje y de descartar neoplasias asociadas, se diagnosticó RS3PE. Se manejó con prednisona y hubo buena respuesta, con remisión de las manifestaciones a las 6 semanas y suspensión posterior del esteroide.
    UNASSIGNED: la RS3PE es una entidad rara y para diagnosticarla se requiere un alto índice de sospecha. Es importante el abordaje completo para descartar cáncer en los pacientes afectados con este síndrome. La prednisona continúa siendo la mejor opción terapéutica.

    OBJECTIVE: We report the case of an 11-year-old boy with posterior microphthalmos who exhibited normal and age appropriate development of visual acuity.
    METHODS: At the initial diagnosis, when he was 3 years old, the best-corrected visual acuity (BCVA) was 20/125 in the right eye (OD) and 20/200 in the left eye (OS) with high hyperopia (cycloplegic refraction +15.75 D sphere OD and +16.25 D sphere OS). Eight years after he began wearing hyperopic glasses, BCVA was 20/16 OD and 20/20 OS. Optical coherence tomography did not reveal a foveal pit in either eye throughout the observation period. However, elongation of the outer segment and widening of the outer nuclear layers were observed.
    CONCLUSIONS: Many cases of posterior microphthalmos demonstrate subnormal BCVA due to an abnormal foveal structure (papillomacular retinal folds, absence of the foveal pit and avascular zone) and high hyperopia. However, if foveal maturity progresses, even if the foveal structure is abnormal, early aggressive amblyopia treatment can result in normal and age appropriate development of visual acuity.

    OBJECTIVE: To present the case of a 37-year-old female with a foveal macrovessel.
    METHODS: The patient had an incidental finding of congenital retinal macrovessel (CRM) in the left eye on optical coherence tomography (OCT). Visual acuity was normal, and slit lamp and dilated fundus examinations were otherwise unremarkable. OCT angiography (OCTA) imaging allowed for visualization of the depth profile of the vessel as well as the foveal avascular zone (FAZ). The FAZ and foveal pit were both smaller in the affected eye compared to the fellow eye.
    CONCLUSIONS: We describe findings of OCTA imaging in a patient with CRM. Previous reports have relied on examination using fluorescein angiography, which does not provide sufficient axial resolution to discern the different vascular plexuses. This report further characterizes how this rare condition can affect foveal morphology and retinal vasculature.

    We report the case of a 12-year-old boy with fovea plana discovered on a systematic work-up. His best-corrected visual acuity was limited to 20/25 in both eyes. Anterior segment examination showed no evidence of iris transillumination or aniridia. Macular OCT revealed persistence of the inner nuclear layers in the foveolar area and an absence of foveal pits, suggesting a diagnosis of fovea plana. Fluorescein angiography revealed that the foveal avascular zone (FAZ) was absent. OCT angiography revealed persistence of the superficial and deep capillary plexi. Our case confirms that OCT angiography affords additional insights into macular exploration and the diagnosis of fovea plana by revealing absence of the foveal pit associated with persistence of both superficial and deep capillary plexi in the foveal area.
