糖尿病视网膜病变是最为常见的糖尿病微血管并发症,主要由糖尿病引起的机体代谢紊乱导致。而然在临床工作中发现,部分患者通过单纯控制血糖以延缓糖尿病视网膜病变进展,所取得效果不甚理想,一些其他因素对于糖尿病视网膜病变的发生、发展,也起到不可忽视的作用。研究表明,在并发高脂血症的糖尿病视网膜病变患者中,胆固醇代谢异常是诱发视网膜病变的主要原因之一。胆固醇代谢异常通过减弱肝脏X受体,导致胆固醇在视网膜上不断积累,降低视网膜血管内皮功能,从而造成视网膜缺血、缺氧环境的形成,又可通过增加炎症因子和细胞黏附分子-1的表达,使原本病态的糖尿病视网膜血管变得更加脆弱,该文总结了糖尿病视网膜病变的病理因素,对比分析当前糖尿病视网膜病变的主要治疗手段,通过分析胆固醇逆向转运(cholesterol reverse transport,RCT)途径转运对糖尿病视网膜病变发生、发展的影响,发现降低高血脂可提高糖尿病视网膜病变的治愈率,这将为糖尿病视网膜病变的临床防治工作提供新思路。
Diabetic retinopathy is the most common diabetic microvascular complication, which is mainly caused by metabolic disorders caused by diabetes. However, in clinical work, it is found that some patients do not achieve satisfactory results in delaying the progress of diabetic retinopathy by simply controlling blood sugar, and some other factors contribute to the occurrence and development of diabetic retinopathy. Also played a role that can not be ignored. Studies have shown that abnormal cholesterol metabolism is one of the main causes of retinopathy in diabetic retinopathy patients with hyperlipidemia. Abnormal cholesterol metabolism leads to the accumulation of cholesterol in the retina and the decrease of retinal vascular endothelial function by weakening the X receptor in the liver, resulting in the formation of retinal ischemia and hypoxia environment. it can also increase the expression of inflammatory cytokines and cell adhesion molecule-1 to make the originally morbid retinal vessels more fragile. This paper summarizes the pathological factors of diabetic retinopathy. By comparing and analyzing the main treatment methods of diabetic retinopathy at present, and by analyzing the influence of cholesterol reverse transport (cholesterolreversetransport,RCT) pathway on the occurrence and development of diabetic retinopathy, it is found that reducing hyperlipidemia can improve the cure rate of diabetic retinopathy, which will provide new ideas for the clinical prevention and treatment of diabetic retinopathy.
Terson综合征又称蛛网膜下腔出血合并玻璃体积血综合征,是一种较为罕见的眼科疾病。患者多因颅内出血而存在意识障碍、沟通困难,极易漏诊,错过最佳治疗时机。该文报道了一例30岁男性患者,因弥漫蛛网膜下腔出血,突发昏迷,于发病1个月后出现双眼视物模糊,最终确诊为双眼Terson综合征,并行双眼玻璃体切割术及右眼视网膜前膜剥膜术治疗。术后54 d,患者左眼视力由指数/5 cm恢复至矫正视力0.3。术后19 d,患者右眼视力由手动/20 cm恢复至矫正视力0.12。
Terson syndrome, also known as subarachnoid hemorrhage combined with vitreous hemorrhage syndrome, is a relatively rare ophthalmic condition. Patients mostly have impaired consciousness and communication difficulties due to intracranial hemorrhage, which makes it very easy to miss the diagnosis and the best time for treatment. This article reports the basic case of a 30-year-old male patient with sudden coma due to diffuse subarachnoid hemorrhage. And he had blurred vision in both eyes 1 month later, which was finally diagnosed as binocular terson syndrome. He was treated with vitrectomy in the left eye and vitrectomy + anterior retinal detachment surgery in the right eye. The visual acuity of patient was restored from finger count/5cm to corrected visual acuity of 0.3 in the left eye when 54 days after surgery and from manual/20 cm to corrected visual acuity of 0.12 in the right eye when 19 days postoperative.

糖尿病视网膜病变是糖尿病引起的微血管病变之一,是不可逆性致盲的眼病。根据其病程可分为根据其病程可分为非增殖期和增殖期,其中还包括糖尿病性黄斑水肿。全科医师需要检测量裸眼视力、矫正视力和眼压,通过裂隙灯显微镜评估眼前节以及眼底检查来评估眼部整体情况。控制血糖、血压、血脂对改善预后很重要。需要重视餐前、餐后血糖,糖化血红蛋白和代谢记忆,一线降血压药物包括血管紧张素转化酶抑制剂和血管紧张素Ⅱ受体阻断剂,调脂药物首选他汀类,而非诺贝特有额外的视网膜保护作用。干预生活方式,宣教,早期发现也同样重要。全科医师需要进行眼底筛查和评分,及时转诊至眼科治疗。眼科治疗包括全视网膜激光光凝术、经平坦部玻璃体切除术、玻璃体抗血管内皮生长因子药物注射术。
Diabetic retinopathy is one of the microvascular diseases caused by diabetes, it is an irreversible blindness eye disease. According to its course, it can be divided into non-proliferative diabetic retinopathy and proliferative diabetic retinopathy, including diabetic macular edema. Te general practitioner needs to measure the uncorrected visual acuity, corrected visual acuity intraocular pressure, use the slit lamp microscope to exam the anterior segment and fundus to evaluate the overall condition of the eye. Controlling blood glucose, blood pressure and blood lipid is very important to improve the prognosis. Attach importance to pre- and postprandial blood glucose, glycosylated hemoglobin and metabolic memory should be carried out. The first-line antihypertensive drugs are angiotensin converting enzyme inhibitors and angiotensin II receptor blockers. Statins are the first choice for lipid-lowering drugs, fenofibrate has additional protective efect of retinal. Intervention in lifestyle, education and early detection are is important. Te general practitioner needs to perform fundus screening and scoring, timely refer to ophthalmology department for treatment. Ophthalmic treatment includes panretinal laser photocoagulation, pars plana vitrectomy, and intravitreal injection of anti-vascular endothelial growth factor drugs.
报告一例视神经脊髓炎谱系疾病(neuromyelitis optica spectrum disorders,NMOSD)合并人体免疫缺陷病毒(human immunodeficiency virus,HIV)感染/获得性免疫缺陷综合征(acquired immune deficiency syndrome,AIDS),并通过文献复习,总结其发病机制、临床特征、治疗及预后。检索文献包括7篇英文文献(8个病例),1篇中文文献,共报道9例NMOSD合并HIV感染/AIDS病例,结合本文报道的1例共10例,其中5例为女性,5例为男性,3例HIV感染/AIDS为新发,其他病例的HIV感染/AIDS发病均早于NMOSD。临床表现上,7例均为视神经炎和脊髓炎同时或相继发生,2例表现为单相病程或复发性脊髓炎,1例仅表现为双眼相继发生的视神经炎,10例患者头或脊髓MRI均有典型的视神经或脊髓异常信号,伴或不伴强化。2例患者未进行水通道蛋白4(aquaporin protein-4,AQP4)抗体IgG检测,其余8例中5例AQP4抗体阳性、3例阴性。针对AIDS的治疗,10例患者中,8例接受了高效抗逆转录病毒治疗(highly active antiretroviral therapy,HAART)。针对NMOSD的治疗,10例患者中,急性期有8例患者接受糖皮质激素冲击治疗、3例患者接受血浆置换、2例接受丙种球蛋白治疗,序贯治疗期有6例患者接受免疫抑制剂治疗,其中1例因高胆红素血症停药。发生视神经炎的7例中,2例患者经治疗仍失明、5例视力部分恢复,发生脊髓炎的8例中,5例患者遗留截瘫或轻瘫、3例肌力部分恢复。1例因严重并发症去世。NMOSD合并HIV感染/AIDS临床较罕见,预后差,往往遗留严重的视力障碍及瘫痪等,临床治疗较为棘手,糖皮质激素和免疫抑制剂并非使用禁忌证,但制定治疗决策前需要充分考虑风险与获益的平衡。
A case of neuromyelitis optica spectrum disorders(NMOSD) complicated with human immunodeficiency virus(HIV) infection/acquired immunodeficiency syndrome(AIDS) was reported, and the pathogenesis, clinical characteristics, treatment and prognosis were summarized through the literature review. The retrieved literatures included seven English literatures (eight cases) and one Chinese literature, in which a total of nine cases of NMOSD co-infected with HIV infection/AIDS were reported. Combined with the case reported in this paper, the total number of cases was ten, among which five cases were female and five cases were male, three cases of HIV infection/AIDS were newly developed, and the other cases had earlier onset of HIV infection/AIDS than NMOSD. In terms of clinical manifestations, seven cases all had simultaneous or sequential optic nerve and myelitis, two patients presented with a uniphasic course or recurrent myelitis, and one case presented only with bilateral optic neuritis occurring sequentially in both eyes. All ten patients had typical abnormal signals of the optic nerve or spinal cord with or without enhancement on cranial or spinal MRI. Two patients did not undergo AQP4 antibody IgG testing , and of the remaining seven cases, five were positive for AQP4 antibodies and three were negative. For AIDS treatment, eight of the ten patients received highly active antiretroviral therapy(HAART). For NMOSD treatment, among the ten patients, eight patients received intravenous methylprednisolone,three patients received plasmapheresis, and two patients received intravenous immunoglobulin in the acute phase. Six patients received immunosuppressive therapy during the sequential treatment period, and one of them was discontinued due to hyperbilirubinemia. Of the seven cases with optic neuritis, two patients remained blind after treatment and five had partial recovery of vision. Of the eight cases with myelitis, five patients were left with paraplegia or mild paralysis, and three had partial recovery of muscle strength. One case died due to serious complications.NMOSD combined with HIV infection/AIDS is rare in clinic and has a poor prognosis. Patients are often left with severe visual impairment and paralysis. Clinical treatment is quite difficult, hormones and immunosuppressive agents are not considered as contraindications. Treatment decisions need to be made with fully considered about the balance of risks and benefits.
