糖尿病患者超声乳化白内障吸除手术的临床观察

目的:探讨糖尿病患者进行超声乳化白内障吸除联合人工晶状体植入手术的临床效果。方法:50例(61只眼)糖尿病患者(设为A组)和同期163例(174只眼)血糖正常患者(设为B组)接受超声乳化白内障吸除联合人工晶状体植入手术。糖尿病患者手术前通过饮食疗法、口服药物或肌注胰岛素治疗,使空腹血糖降到 10mmol/L以下。术后随访 1～28个月(平均 8.6个月),复查视力、裂隙灯及眼底检查。结果:术后矫正视力≥0.5者,A组为77.1%;B组为80.5%。两组经统计学处理差异无显著性(P>0.05)。两组术中出现后囊破裂及术后发生角膜水肿和前房渗出等并发症的差异无显著性(P>0.05 )。结论:糖尿病患者进行超声乳化白内障吸除手术前只要有效控制血糖,其手术效果与对照组患者相同。但术后血糖的控制仍然十分重要。眼科学报2003;19:98-100。     

高度近视的病因学研究进展

高度近视发生的内因、外因，包括遗传倾向，相关基因定位，巩膜胶原白体免疫学说，视网膜生物活性物质失调学说，环境因素等，本研究就这些因素对高度近视发病的影响做一综述。现统一的认识有：①高度近视具有明显的遗传倾向。②迄今为止，已找到4个高度近视相关基因，它们的遗传方式均为常染色体显性遗传。③高度近视的巩膜组织病理改变和胶原代谢障碍引发了人们对高度近视免疫相关基因的深入研究。已发现HLAⅡ类基因与部分高度近视具有相关性。④视网膜中存在的生物活性物质直接或间接参与了形觉剥夺性近视的形成。⑤环境因素并非高度近视发病的决定因素，它仅起一定程度的促进作用。将今后的工作重点放在高度近视基因定位的研究，基因表达的调控及巩膜胶原代谢、网膜生物活性物质之间的关系研究上，无疑会进一步揭示高度近视的病因，为防治高度近视开辟新途径。

In vivo quantification of fluorescent molecular markers in real-time: A review to evaluate the performance of five existing methods

With the advent of molecular-targeted fluorescent markers, there is a renewed interest in fluorescence quantification methods that are based on continuous wave excitation and multi-spectral image acquisition. However, little is known about their in vivo quantification performance. We reviewed the performance of five selected methods by analytically describing these and varying input parameters of irradiance, excitation geometry, collection efficiency, autofluorescence, melanin content, blood volume, blood oxygenation and tissue scattering using optical properties representing those for human skin. We identified one method that corrects for variations in all parameters. This requires image acquisition before and after marker administration, under identical geometry. Hence, it is suited for applications where the site of interest can be relocated (e.g. anaesthetized animals and dermatology). For applications where relocation is not possible, we identified a second method where the uncertainty in the fluorescence signal was ±20%. Hence, use of these methods can substantially aid in vivo fluorescence quantification compared to use of the raw fluorescence signal, as this changed by more than 3 orders of magnitude. Since these methods can be computed in real-time, they are of particular interest for applications where direct feedback is critical, as diagnostic screening or image-guided surgery.     

Planning for minimally invasive unicompartmental knee arthroplasty

Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications, and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical procedure.
