中低度近视FS-LASIK、SMILE及ICL植入术的效果比较

目的比较飞秒激光制瓣准分子激光原位角膜磨镶术(FS-LASIK)、全飞秒激光小切口角膜基质透镜取出术(SMILE)和有晶状体眼后房型人工晶状体(ICL V4c)植入术三者矫正中低度近视的效果。方法采用回顾性研究。以惠州爱尔眼科医院2019年6月至2020年4月矫正中低度近视120例(120眼)作为研究对象,受术者分为FS-LASIK组、SMILE组及ICL组,每组40例(40眼),各组分别接受相应的手术,术后随访3个月比较其矫正效果。结果术后1个月及3个月,3组间视力及有效性指数对比差异无统计学意义(P>0.05);ICL组安全性指数高于SMILE组及FS-LASIK组(P<0.05)。术后3个月FS-LASIK组的三叶草像差、彗差和球差出现明显变化,而SMILE组的变化较小,ICL组变化最小(P<0.05)。结论对中低度近视FS-LASK、SMILE及ICL植入术三者均有确切疗效,而ICL V4c植入术的安全性最高,患者的视觉质量最好。     

上海市某社区小学生近视状况及相关因素分析

【目的】了解上海市闵行区小学生近视状况及相关因素分析。【方法】选取2019年1月1日至12月31日期间参加屈光筛查的11 356名6~10岁小学生作为本次研究的对象,调查项目包括视力检查和电脑验光。【结果】6~10岁社区小学生近视检出率45.59%。女性高于男性,6~10岁检出率分别为22.88%、31.77%、47.62%、60.53%、69.84%,呈线性趋势(χ²=1.31,P<0.001)。多因素logistic回归分析结果显示,性别、年龄、父母近视状态是社区小学生屈光近视的影响因素;出生体重、是否早产、体重指数(BMI)对社区小学生屈光近视无影响。【结论】社区儿童青少年屈光近视的检出率较高,且不同人群特征检出情况有所差异,因此需针对不同年龄段、不同学生特征儿童青少年采取综合施策优先,重点人群重点防控的多层次防控策略。     

玻切二期术后低视力人群的护理策略

目的对玻切二期术后低视力人群采取特殊的护理策略,来平复病人的负面情绪,提高治疗满意度。方法对2019年11月6日至2020年11月6日在我院接受玻璃体切割二次手术的96名低视力患者进行特殊护理干预,然后进行回顾性分析。结果在结合实际病情分析采取的特殊护理策略干预下,病人术后情绪稳定,未出现不良投诉事件,满意度较高。结论对玻切二期术后低视力人群采取特殊的护理干预策略十分必要。     

Revisión de los principales test clínicos para evaluar la visión del color

Introduction

Congenital colour vision deficiencies affect 8% of the male and 0.5% of the female population. The study of colour vision is a complex process due to several factors: the psychophysics of vision itself, the difficulty to establish mathematical models for its analysis, the vague correlation of results between different tests, and the influence of external factors such as lighting, the tests condition, or the experience of the examiner and the patient. In the present document, a simplified review was carried out on the main colour vision tests available in clinical practice.

Development of a protocol for maintaining viability while shipping organoid‐derived retinal tissue

Retinal organoid technology enables generation of an inexhaustible supply of three‐dimensional retinal tissue from human pluripotent stem cells (hPSCs) for regenerative medicine applications. The high similarity of organoid‐derived retinal tissue and transplantable human fetal retina provides an opportunity for evaluating and modeling retinal tissue replacement strategies in relevant animal models in the effort to develop a functional retinal patch to restore vision in patients with profound blindness caused by retinal degeneration. Because of the complexity of this very promising approach requiring specialized stem cell and grafting techniques, the tasks of retinal tissue derivation and transplantation are frequently split between geographically distant teams. Delivery of delicate and perishable neural tissue such as retina to the surgical sites requires a reliable shipping protocol and also controlled temperature conditions with damage‐reporting mechanisms in place to prevent transplantation of tissue damaged in transit into expensive animal models. We have developed a robust overnight tissue shipping protocol providing reliable temperature control, live monitoring of the shipment conditions and physical location of the package, and damage reporting at the time of delivery. This allows for shipping of viable (transplantation‐competent) hPSC‐derived retinal tissue over large distances, thus enabling stem cell and surgical teams from different parts of the country to work together and maximize successful engraftment of organoid‐derived retinal tissue. Although this protocol was developed for preclinical in vivo studies in animal models, it is potentially translatable for clinical transplantation in the future and will contribute to developing clinical protocols for restoring vision in patients with retinal degeneration.     

鞍山市学生常见病调查及相关因素分析

目的 调查鞍山市学生常见病情况,并对其相关因素进行分析。方法 2018年9～11月选择鞍山市1个城区和1个县(铁东区和千山区),共监测13所学校,其中城区8所学校,县5所学校,其中包含小学到大学,调查学生常见病发生情况,分析不同年级、性别、地区学生常见病差异性。结果 鞍山市学生视力不良检出率最高,占53.77%,其次为恒牙龋齿,占21.11%;随着年级的增长视力不良检出率呈现出升高趋势(P0.05);与城区相比,县级学校视力不良、恒牙龋齿检出率明显偏高,且女性高于男性,差异有统计学意义(P0.05);随着年级增长,营养不良检出率逐渐降低(P0.05)。结论 鞍山市学生健康状况不容乐观,其中视力不良、龋齿以及营养不良等成为影响学生健康的主要卫生问题,应给予高度重视。     

参黄洗液辅助吻合器痔环切手术治疗混合痔效果及其预后不良早期预警

目的:对参黄洗液辅助吻合器痔环切手术(PPH手术)在混合痔治疗中的效果及其预后不良早期预警的价值进行研究,为临床治疗和不良反应的防治提供数据参考。方法:选取2018年5-12月我院手术治疗的混合痔患者120例为研究对象,采用随机数表法分为观察组和对照组,每组60例。观察组采用参黄洗液辅助PPH手术治疗,对照组PPH术后采用高锰酸钾溶液坐浴治疗。术后辅助治疗20d后就疗效、不良反应及随访3个月的远期疗效进行评价和组间比较,并对观察组预后不良病例的早期反应进行分析。结果:观察组总有效率为96.67%(58/60),高于对照组86.67%(52/60)的总有效率(P<0.05);观察组不良反应发生率为21.67%(13/60),低于对照组31.67%(19/60)的不良反应发生率(P<0.05);观察组病例不良预后发生率为25.00%(15/60),低于对照组33.33%(20/60)的不良预后发生率(P<0.05)。结论:参黄洗液辅助PPH手术在混合痔治疗中具有疗效显著、安全性高、预后良好等优势,临床具有推广价值。
