栓塞治疗颈动脉海绵窦瘘的良好效果(英文)

目的:报告外伤后颈动脉海绵窦瘘患者应用螺圈栓塞的成功经验。方法:连续病例。结果:两名颈动脉海绵窦瘘(CCF)患者成功接受了螺圈栓塞治疗。他们分别在机动车事故后2wk和4mo出现CCF的临床症状。一名患者视力良好但眼内压(IOP)升高,另一名则视力低下伴有临界眼内压。CCF的诊断均得到脑血管造影证实,采用螺圈栓塞治疗后两名患者视力恢复正常,在未用任何抗青光眼药物前提下眼压降至正常范围。CCF的症状诸如眼球突出,眼肌麻痹,结膜充血水肿,眼眶杂音及眼底改变也随之消失。结论:颈动脉海绵窦瘘宜早诊断和治疗以避免发生视力丧失严重并发症的发生,血管内栓塞是当代治疗选择。     

Clinical profile and aetiology of optic neuritis in Hospital Universiti Sains Malaysia--5 years review

Although few studies concerning optic neuritis (ON) in Asian countries have been reported, there is no report about ON in Malaysia particularly within the Malay population. We aimed to determine the clinical manifestation, visual outcome and aetiology of ON in Malays, and discussed the literature of ON studies in other Asian populations. This was a retrospective study involving 31 consecutive patients (41 eyes) with ON treated at Hospital Universiti Sains Malaysia commencing from July 2005 till January 2010 with a period of follow-up ranging from 18-60 months. The clinical features, laboratory results, possible aetiology, and visual acuity after one year were analysed. Females were the predominant group. The age of the patients ranged between 3-55 years and peaked between 21-30 years old. 67.7% of the patients had unilateral involvement. Pain on ocular movement was observed in 31.7% of the affected eyes. 73.3% of 41 involved eyes showed visual acuity equal 6/60 or worse on presentation. Paracentral scotoma was the most common visual field defect noted. Optic disc papillitis proved more widespread compared to the retrobulbar type of ON. The aetiology was idiopathic in more than 50%, while the risk of multiple sclerosis was extremely low (3.2%) in our series. 66.0% demonstrating visual acuity improved to 6/12 or better at one year after the attack. 16.1% showed evidence of recurrence during follow-up. In conclusion, the clinical profile and aetiology of ON in Malay patients are comparable to other ON studies reported by other Asian countries.

Developmental competence of transported in-vitro matured macaque oocytes

This study examines in-vitro maturation (IVM) in a non-human primate model, Macaca fascicularis. The animals had hormonal injections and laparoscopic oocyte retrieval (OR)) at 12- and 24- h after human chorionic gonadotrophin (HCG). The immature oocytes were placed in tightly capped tubes containing pre-equilibrated IVM medium and transported for 5 h in a dry portable 37 degrees C incubator without CO2 supplement. Meiotic spindle was observed at 36-38- h post-HCG by polarized microscopy in 72 and 84.5% of mature oocytes collected at 12- and 24- h post-HCG oocyte retrieval intervals respectively. However, abnormal spindle formations were detected in some IVM oocytes by confocal microscopy. The IVM oocytes were also randomly selected for (i) intracytoplasmic injection with frozen-thawed epididymal M. fascicularis spermatozoa and (ii) nuclear transfer (NT) with fresh M. fascicularis cumulus cells. Embryonic development of sperm-injected embryos was not affected by the 12- and 24- h post-HCG oocyte retrieval intervals (22.5 versus 27.9% respectively). However, embryonic development of NT embryos was significantly affected by the 12- h post-HCG oocyte retrieval interval (4.5 versus 31.7% respectively; P < 0.01). In conclusion, IVM of monkey oocytes in a dry portable incubator for 5 h did not affect the maturation rate. However, the ability of primate oocytes to develop after somatic cell nuclear transfer was affected by oocyte retrieval time post-HCG.     

The Diabcare-Asia 1998 study--outcomes on control and complications in type 1 and type 2 diabetic patients

The aim of this study was to describe the glycaemic and metabolic control and diabetes-related complications in type 1 and type 2 Asian patients. METHODS: Data of diabetes patients from 230 diabetes centres in 12 Asian regions were collected on a retrospective-prospective basis through review of medical records, interview and laboratory assessments. Analysis of glycated haemoglobin (HbA1c) was carried out in central laboratories appointed by Bio-Rad. The data collection case record forms were scanned electronically. RESULTS: 22177 patients with valid data made up the analysis population. Among patents with type 1 and type 2 diabetes, there was a higher proportion of women than men (53% vs. 47% for type 1 patients and 56% vs. 44% for type 2 diabetes). Hypertension (61%) and overweight (40% with BMI > or = 25 kg/m2 were common in type 2 patients. Dyslipidaemia was also present in at least half of both types of patients. Control of glycaemia (mean HbA,1c and fasting blood glucose [FBG]) was poor in type 1 (9.9 +/- 2.5%; 10.2 +/- 5.2 mmol/l) and type 2 patients (8.5 +/- 2.0%; 8.9 +/- 3.4 mmol/l). Glycaemia in the majority of both types of patients fell short of those stipulated by various guidelines. In type 2 patients, glycaemia deteriorated (HbA1c > 7.5%, FBG > or = 7.0 mmol/l) with duration of diabetes > 7 years. Both types of diabetes appear to share a similar high prevalence of complications of cataract, retinopathy and neuropathy, although the prevalence of cataract (27%) and neuropathy (35%) was higher in type 2 diabetes. Screening for microalbuminuria was not common. CONCLUSIONS: The Inadequate metabolic and hypertension control, especially in type 2 patients, needs to be addressed.

晶状体异物所致单眼轻度前葡萄膜炎1例(英文)

报道1例晶状体内异物所致单眼轻度前葡萄膜炎。患者,男,25岁,以"右眼持续畏光,流泪2mo"主诉就诊,无痛性视力下降。之前有金属物体敲击史。眼科检查显示轻度前葡萄膜炎,晶状体内存留异物,无眼部充血。CT检查证实球内异物。这种情况容易被漏诊和误诊,详细的病史采集和临床检查对避免误诊至关重要。     

成人Coats病1例

目的:报告成人Coats病1例,并探讨其引起的视网膜病变。方法:病例报告。结果:马来西亚63岁糖尿病患者1例,男,右眼无痛性视力下降1a,视力指数/2英尺,而左眼最佳矫正视力为6/12。右眼眼底表明颞侧后极部出现广泛的视网膜渗出物,可累及黄斑区和鼻侧视盘。异常分布的多区域血管位于黄斑颞侧且呈衰减趋势。眼底荧光血管造影显示,毛细血管扩张在视网膜渗出区域且有荧光素渗漏现象存在。左眼表现正常。根据临床和FFA结果,患者被诊断为成人Coats病,右眼行氩激光光凝治疗。激光后6mo,患者的视力保持在6/120并出现视网膜最小限度的回退。结论:临床和血管造影结果是视网膜毛细血管扩张症的重要诊断依据。渗漏区域激光光凝治疗有利于防止视力丧失。     

梅毒性葡萄膜炎3例

目的:评估梅毒性葡萄膜炎患者的临床表现和视力。方法:梅毒性葡萄膜炎患者3例在USM医院接受治疗。结果:患者3例被诊断为继发性梅毒性葡萄膜炎,这3例患者患病之前均不知道患有梅毒,但他们有明确的乱交史。并且每个月都伴有逐步的视力下降。其中两人伴有发热、眼痛、眼前悬浮物。视力从6/12到手动。所有患者均出现前葡萄膜炎,玻璃体炎和视神经炎。第一例患者出现了多灶性脉络膜视网膜炎,并伴有渗出性视网膜脱离。第二例患者出现渗出性视网膜脱离,而第三例患者仅出现了脉络膜视网膜炎。所有患者每周注射苄青霉素2.4MU,共4wk,其中2例患者口服多西霉素200mg2次/d,共3mo。治疗效果良好,其中2例患者有显著的视力上升,分别从6/120到6/21和6/12到6/6。其中较严重的1例患者出现逆转录酶为阳性。结论:眼梅毒作为非肉芽肿性的炎症与渗出性视网膜脱离有关。治疗后虽然视力恢复比较缓慢,但普遍有良好的效果。     

马来西亚视神经萎缩的临床特点及病因

目的：研究在马来西亚非青光眼视神经萎缩的病因及临床特点。

方法：一系列回顾性的研究分析马来西亚理科大学校医院眼诊所在2007/2011年间被诊断为非青光眼视神经萎缩的患者。至少随访1a。评估这些患者的医疗记录及汇编调查结果。

结果：100例患者符合选择标准,56%的患者双眼都参与研究。主要症状为视力模糊(61%),除了视力模糊外还出现神经方面病症(18%),视野狭窄(9%)。大多数患者(63%)患眼视力下降到3/60以下。主要的病因是颅内占位性病变(26%),先天性疾病(13%),脑积水(12%),创伤(12%)及血管因素(12%)。对大多数患者(67%)采用保守治疗。不管其病因,视神经萎缩都伴有不同程度的视功能障碍。随访1a后,50%的患者出现不同程度的视觉障碍。

结论：视神经萎缩主要的病因是颅内占位性病变,其次分别是先天性疾病,创伤和血管疾病。在诊断之前常常就出现视觉和神经上的症状,而疾病显著地影响着视力的变化。为了早期诊断视神经萎缩,当视力模糊的主诉为非特异性时,应该高度怀疑本病。
