高度近视(high myopia，HM)作为一种特殊类型的屈光型眼病，不仅会导致进行性、退行性眼底改变，其视神经损伤的患病率也很高。青光眼是全球范围内最常见的一种不可逆致盲性眼病，原发性开角型青光眼(primary open-angle glaucoma，POAG)是最常见的青光眼类型。近年来的研究发现HM与POAG的病理改变存在相似之处。由于HM眼底改变与早期POAG眼底改变容易混淆，HM患者早期发现POAG对延缓或阻止疾病进展很重要。HM患者长期随访不仅要观察黄斑病变，视神经形态与结构改变的观察也不容忽视。
As a special type of refractive eye disease, high myopia (HM) not only causes progressive and degenerative fundus changes, but also has a high prevalence of optic nerve damage. Glaucoma is the most common form of irreversible blinding eye diseases worldwide, among which, primary open-angle glaucoma (POAG) is the most common type. In recent studies, HM is found to have similarities on pathological changes as that of POAG. And HM fundus changes are easily confused with early stage POAG fundus changes; thus, the early detection of POAG on HM patients is highly important on disease deferment or prevention of disease progression. Macular degeneration as well as optic nerve morphology and structural changes are to be observed in the long-term follow-up for HM patients.
内源性真菌性眼内炎(endogenous fungal endophtalmitis, EFE)是最具破坏性的眼部感染之一，在临床上较少见。如诊断和治疗不及时，可严重损害患者视力，甚至需摘除眼球。由于EFE发病隐匿，病程较长，病原学涂片和培养阳性率较低，早期临床症状与葡萄膜炎相似，极易被误诊和漏诊，延误治疗时机。EFE最常见的感染灶来源为肝脏、肺、尿路、脑膜炎、胃肠道、心内膜以及骨髓。文章报道了一例腰椎感染致双眼内源性念珠菌性眼内炎的男性患者，66岁，因“右眼视力下降1周”首诊于眼科，专科检查见右眼玻璃体炎性混浊，初诊为右眼葡萄膜炎，予抗炎等治疗症状无好转，右眼视力持续下降，右眼前房穿刺抽液送检提示：热带念珠菌感染，之后左眼视力也逐渐下降，加之患者近期于骨科住院，术中腰椎间盘退变的纤维软骨组织DNA-病原微生物宏基因组检测结果示热带念珠菌，考虑双眼EFE，予全身及局部使用抗真菌药物联合双眼玻璃体切割手术，治疗后患者视力恢复良好，随访1年无复发。该病例及相关文献回顾，有助于加深临床医生对此类疾病的认识，为今后临床诊疗提供一定思路，也起到一定警示作用。
Fungal endophthalmitis is one of the most destructive eye infections and is relatively rare in clinical practice.If not diagnosed and treated promptly, it can severely damage vision and even lead to enucleation.Due to its insidious onset, long course, low positive rates in smears and cultures, and early clinical symptoms similar to uveitis, it is prone to misdiagnosis and missed diagnosis, leading to delayed treatment. A review of the literature indicates that the most common sources of EFE infection are the liver, lung, urinary tract, meningitis, gastrointestinal tract, endocarditis and osteomyelitis.In this paper, we report a case of lumbar spine infection causing bilateral candidal endophthalmitis in a 66-year-old male patient.He initially presented to the ophthalmology department of our hospital with a one-week history of decreased vision in the right eye, specialized examination revealed inflammatory opacity in the vitreous of the right eye, initially diagnosed as uveitis and treated with anti-inflammatory therapy without improvement.As the vision in the right eye continued to decline, aqueous humor aspiration from the anterior chamber of the right eye indicated infection with tropical Candida.Subsequently, the vision in the left eye also gradually decreased.Considering the recent hospitalization in the orthopedic department for lumbar disc degeneration, metagenomics analysis of fibrous cartilage tissue DNA during surgery detected tropical Candida, suggesting bilateral endogenous fungal endophthalmitis,The patient was treated with systemic and local antifungal medications in combination with bilateral vitrectomy surgery.After treatment, the vision recovered well, and there was no recurrence during a one-year follow-up.The objective of this thesis is to deepen the understanding of clinicians on this type of disease by reporting this case and reviewing relevant literature, providing some insights for future clinical diagnosis and treatment, and serving as a warning.
局限性脉络膜凹陷(focal choroidal excavation,FCE)是表现为光感受器细胞层、视网膜色素上皮层向脉络膜层凹陷的眼底病变。发病机制多认为是先天脉络膜发育异常、炎症或感染。基于光学相干断层扫描(optical coherence tomography,OCT)，可将FCE从光感受器尖端与视网膜色素上皮层是否分离、形态特征或中央脉络膜厚度三种方式对其进行分类。FCE常合并脉络膜新生血管等疾病。该文对FCE的临床研究现状做一综述。
Focal choroidal excavation (FCE) is a retinopathy, expressing with a depression in photoreceptor cell layer and retinal pigment layer towards the choroidal layer. The pathogenesis is recongized as congenital choroidal developmental abnormalities, inflammation, or infection. Based on optical coherence tomography (OCT), FCE can be classified by three methods: the situation of photoreceptor separating from the retinal pigment upper cortex, morphological features, or central choroidal thickness. FCE is usually associated with other diseases such as choroidal neovascularization. This article reviews the current clinical research on FCE.

Focal choroidal excavation (FCE) can be defined as an excavation into the choroid along the retinal pigment epithelium (RPE) based on optical coherence tomography (OCT) without evidence of corresponding staphyloma or other scleral changes. The pathogenesis is usually congenital choroidal dysplasia, inflammation or infection. Based on optical coherence tomography images, FCE can be classified in three ways: whether the photoreceptor cell layer is separated from the retinal pigment epithelium, morphological characteristics or central choroidal thickness. FCE is often associated with choroidal neovascularization and other diseases. This article will review the clinical research status of FCE.
