眼表菌群是定植于眼表的各种微生物群落，以细菌为主。在正常情况下，眼表菌群与人体眼表组织的细胞和平共生，维持眼表的稳态，共同保证眼表的健康。但在环境改变或免疫力低下的情况下，眼表菌群会发生变化，与眼部疾病的产生与发展关系密切，对人类的健康造成巨大的危害。随着组学研究的不断发展，我们对眼表菌群有了新的认识，为眼表疾病的发病机制、治疗开辟了新的思路，同时也提出了新的挑战。本文对国内外眼表菌群与疾病关系进行综述，为眼表疾病的发生、发展以及治疗提供参考。
The microbiome of the ocular surface consists of various microbial communities that colonize on the eye surface, mainly bacteria. The stabilization of the microbiome and the other ocular surface components plays an important role in maintaining the homeostasis of the ocular surface. However, unpredictable changes of ocular surface microbiome are strongly associated with ocular surface diseases in the situation of environmental changes or destruction of immune system. With the innovation of inspection technology, the current gene sequencing technology is applied to detect the ocular surface microbiome and confirm that the eye microbiome is closely related to ocular surface diseases. This paper investigates the corelation of ocular surface microbiomes and diseases. Moreover, we provide areference for the occurrence and development of ocular surface diseases and their treatment.
霜样树枝状视网膜血管炎是一种少见的急性视网膜血管炎，多发生于健康青少年，病因不明，可能与病毒感染有关，糖皮质激素治疗有效，预后良好；也可继发于感染性疾病和全身疾病，预后较差。该文回顾了一例继发于异基因造血干细胞移植后的霜样树枝状视网膜血管炎，治疗后病情缓解，预后良好。
Frosted branch angiitis (FBA) is a rare acute retinal vasculitis which often occurs in healthy adolescents. The etiology of FBA is unknown, but its occurrence may be related to viral infection, glucocorticoid therapy is effective and has a good prognosis. FBA may also be secondary to infectious and systemic diseaseswith poor prognosis. In this paper, we reviewed a case of FBA secondary to allogeneic hematopoietic stem cell transplantation, which was relieved after treatment and had a good prognosis.
Purtscher样视网膜病变是一种少见的视网膜血管性疾病，该文分析了13例Purtscher样视网膜病变的临床特征。典型的眼底表现包括 Purtscher斑22眼、棉絮斑22眼、视网膜出血13眼、黄斑水肿22眼、视盘水肿12眼和假樱桃红斑10眼。荧光素血管造影异常表现包括毛细血管无灌注区21眼，毛细血管前闭塞22眼。13例患者中有9例使用糖皮质激素、免疫抑制剂，4例使用改善循环、营养神经等治疗。随访2周至5年，4例患者(6眼)在随访期间出现神经上皮萎缩并持续低矫正视力(<0.1)。基于文献回顾，讨论了Purtscher样视网膜视力恢复不佳可能与黄斑水肿及无灌注区形成有关。
Purtscher-like retinopathy is a rare retinal vascular disease. In this study,the clinical characteristics of 13 cases of Purtscher-like retinopathy were analyzed. Typical fundus abnormalities included Purtscher flecken (22 eyes), cotton-wool spots (22 eyes), retinal hemorrhages (13 eyes), macular edema (22 eyes), swelling of optic disk (12 eyes), and falsecherry red spots (10 eyes). The abnomal manifestations of fluorescein angiography included non perfusion area of capillaries (21 eyes), and precapillary occlusion (22 eyes). Among 13 patients, 9 patients were treated with glucocorticoids and immunosuppressive drugs, and 4 patients were treated with circulation-improving and neurotrophic drugs. During the follow-up period of two months to five years, four patients (six eyes) experienced neuroepithelial atrophy and persistent low vision (<0.1). Based on literature review, we proposed that the prognosis of vision in Purtscher-like retinopathy may be associated with macular edema and the formation of capillary non-perfusion.
视网膜静脉阻塞(retinal vein occlusion，RVO)是发生率仅次于糖尿病性视网膜病变的视网膜血管病。RVO后导致视网膜血管损伤进而引起血管闭塞，造成视网膜缺血从而促进异常视网膜新生血管(retinal neovascularization，RNV)的增生，晚期发生玻璃体积血、新生血管性青光眼等并发症，积极治疗可以稳定患者的眼部情况，避免并发症的发生。本文报告了1例患有高血压病的23岁年轻女性患者发生视网膜分支静脉阻塞并发新生血管增殖膜的病例，给予病变区视网膜激光光凝治疗，10年后随访发现RNV膜机化萎缩。
Retinal vein occlusion (RVO) is the second most common retinal vascular disease after diabetic retinopathy. Retinal vascular damage after RVO leads to venous occlusion, which further causes retinal ischemia and promotes abnormal retinal neovascularization (RNV). Later complications such as vitreous hemorrhage and neovascular glaucoma occur. Active treatment can stabilize the ocular condition of patients and avoid the occurrence of complications. This paper reports a case of a 23-year-old young female patient with hypertension who developed branch RVO complicated by neovascularization membrane. The lesion area was treated with laser photocoagulation. The RNV was found to be mechanized and atrophied after 10 years of follow-up.
