病理性近视相对高度近视而言，更强调眼底并发症的存在。后巩膜葡萄肿(posterior staphyloma，PS)被认为是病理性近视的标志性特征，是眼球后巩膜壁的局部扩张，通常认为与巩膜变薄和脉络膜萎缩等因素相关。近年来研究认为PS的形成可能与局部炎症、Bruch膜缺失等因素密切相关。伴随OCT等检查技术的快速革新以及PS治疗手段的探索，诊断和治疗更加完善。

Pathological myopia emphasizes the existence of fundus complications. Posterior staphyloma, considered as a hallmark of pathological myopia, is a partial extension of the posterior scleral wall, which is believed to be related to the scleral thinning and choroidal atrophy. In recent years, studies have indicated that the formation of posterior staphyloma may closely connected with localized inflammation and defects of Bruch’s membrane. With the rapid innovation of examination technologies such as optical coherence tomography (OCT) and the exploration of treatment for posterior staphyloma. The diagnosis and therapy will be more comprehensive in the future.

视网膜微循环与脑小血管具有相似的特征。视网膜被认为是可检测到的“窗口”，以检测在神经退行性疾病中发生的微血管损伤。光学相干断层扫描血管造影(optical coherence tomography angiography，OCTA)是一种非侵入性成像方式，可提供视网膜、脉络膜和视神经中血流的深度分辨图像。现总结有关OCTA在与眼科相关的阿尔茨海默病、帕金森病、多发性硬化症及视神经退行性疾病等神经系统疾病中的应用，并讨论其可否作为早期诊断和监测神经退行性疾病的重要工具。

Retinal microcirculation shares similar features with cerebral small blood vessels. Thus, the retina may be considered as an accessible ‘window’ to detect the microvascular damage occurred during the development and progression of neurodegenerative disorders. Optical coherence tomography angiography (OCTA) is a non-invasive imaging modality providing in-depth and high-resolved images of blood flow in the retina, choroid, and optic nerve. In this review, we summarize the current advances in the application of OCT-A in neurological diseases associated with ophthalmology such as Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and optic nerve degenerative diseases. Future directions for evaluating whether OCTA can be used as an important tool to early diagnose and monitor the neurodegenerative disorders are also discussed.

近些年来，眼科疾病的临床诊断治疗及其病理发展的研究对医学影像学技术的要求日益增高，磁共振技术已广泛应用于研究眼科疾病的发病机制、治疗和分析预后。基于体素的形态学分析(voxel-based morphometry，VBM)作为一种新型的磁共振图像的分析方式，VBM可以对活体脑进行无创的形态学研究，定量分析磁共振图像中每一个单独体素内的白质、灰质的密度和体积的变化，从而反映对应区域的解剖学结构差异，能发现常规MRI不能检测到的灰质和白质结构的细微改变。不同于那些只作用于预设的感兴趣区域的分析方法，VBM完全没有偏向性，它探测全脑的异常变化，无需对感兴趣区的先验性假设，不会被研究人员的主观思维影响。这提供了一种全新的方法来探索眼科疾病中的神经病理变化，尤其在青光眼和弱视的研究中应用最多。

With the increasing requirements for medical imaging technologies in clinical diagnosis, treatment and pathological basis research of ophthalmic diseases, magnetic resonance imaging (MRI) has been broadly used in the diagnosis and prognostic evaluation of ophthalmic diseases. As a novel analytic method of MR images, voxel-based morphometry (VBM) quantitatively analyzes the changes in brain gray, white matter density and volume in each individual voxel in MR images to reflect the differences of anatomical structures in the corresponding areas, and it provides a novel way to reveal the neuronal pathological changes in ophthalmic diseases.

结节性硬化症(tuberous sclerosis complex，TSC)是一种累及多系统的常染色体显性遗传病，早期呈单一表现，容易漏诊、误诊，以眼部症状为首发特征的新生儿期病例少有报道。本文报告1例早产男婴，出生后1 d眼底筛查发现右眼视网膜散在多个灰白色半透明隆起灶及脱色素斑，回溯胎儿期超声心动图异常高度怀疑TSC，进一步行头颅MRI检查及家族基因检测，在新生儿期明确了这一诊断。

Tuberous sclerosis complex is a multisystemic disease with an autosomal dominant inheritance pattern. Missed diagnosis and misdiagnosis are common for patients with single manifestation in the early stage. There are few documented neonatal cases with ocular symptoms as primary presentation. Here we report a newborn boy presented with retinal hamartoma, retinal achromic patch, fetal cardiac rhabdomyoma and subependymal nodules. Subsequent genetic tests confirm a diagnosis of TSC.
