Aim: To evaluate the knowledge, attitude and practice about diabetic retinopathy among diabetic patients, attending the endocrinology department of Nampula Central Hospital in Mozambique. Materials and Methods: A descriptive cross-sectional study was conducted at Endocrinology Department of Nampula Central Hospital in Mozambique. Patients’ knowledge, attitude and practice were assessed using a 90-point semi-structured questionnaire. Patients were classified into different categories according to their knowledge, attitude and practice. Data analysis was performed with the aid of SPSS version 20, where frequency distribution and measures of central tendency (mean, median and standard deviation) were used to summarize the descriptive part of the study. The median of Likert scale was calculated and used to identify the majority opinion for questions related to Diabetic retinopathy. Participants were included in the study as part of the sample after signing informed consent. Results: A sample of 305 participants was studied, where 163(53.4%) were male and 142(46.6%) were female; the mean age of the participants was 52.08(±13.04) years. The mean duration of diabetes was 7.2(±6.3) years. The most prevalent treatment was the combination of diet with medication represented by 51.8%. The participants had an average score of 3.98 in the knowledge section and a satisfaction level of 58.0%. The average score in the attitude was 2.92, being negative in 51.5%, and about practice they scored in average 3.49, being positive in 51.5% of the participants. Conclusion: Study participants have satisfactory knowledge and favorable practices regarding diabetic retinopathy, but the majority’s attitude is negative.
目的:了解莫桑比克南普拉中心医院内分泌科糖尿病患者对糖尿病视网膜病变的认识、态度和行为。材料和方法:在莫桑比克南普拉中心医院内分泌科进行了一项描述性横断面研究。采用90分半结构化问卷对患者的知识、态度和行为进行评估。根据患者的知识、态度和行为将患者分为不同的类别。数据分析使用SPSS version 20进行，其中使用频率分布和集中趋势(平均值，中位数和标准差)的度量来总结研究的描述性部分。计算李克特量表的中位数，并用于确定与糖尿病视网膜病变相关问题的多数意见。在签署知情同意书后，参与者被纳入研究，作为样本的一部分。结果:共305人，其中男性163人(53.4%)，女性142人(46.6%);参与者平均年龄为52.08(±13.04)岁。糖尿病的平均病程为7.2(±6.3)年。以饮食加药物治疗为主，占51.8%。参与者在知识部分的平均得分为3.98，满意度为58.0%。态度的平均得分为2.92分，消极的占51.5%;练习的平均得分为3.49分，积极的占51.5%。结论:研究对象对糖尿病视网膜病变有满意的认知和良好的行为，但大多数人的态度是消极的。

Purpose of Study: To evaluate tear film instability after cataract surgery by measuring tear break up time. Place of Study: This study was carried out in Teaching Hospital, University of Lahore, Lahore, Pakistan. Materials and Methods: A descriptive cross- sectional study was conducted in Teaching Hospital, UOL. Tear break up time was measured on patients post-operatively who under -went cataract surgery. A total of 60 patients were included in study after non –probability convenient sampling technique. Both male and female patients were included in study age 45-65 years. Data was collected through self-designed questionnaire based proforma. Further results were analyzed using SPSS version 20. Results: Tear break up time was found statistically reduced at 1 week, 2 week and after one month postoperatively(P =.0002, P<.0001). However, the tear film stability had reverted to approximately the preoperative measurement 1 month after surgery. The mean values of postoperative results were altered from preoperative measurement values. BUT outcomes had reduced considerably at 1 week postoperatively (P=.0001) but had resumed to very nearly the preoperative value 1 month after of cataract surgery. While goblet cell density (GCD) had reduced considerably at 1 week, 2 weekand 1 month postoperatively (P<.0001). Conclusion: This study concludes that tear breakup time is significantly reduced after cataract surgery due to destruction of goblet cells as shown in above tables. But tear break up time is significantly improved after one week, two weeks and one month of follow ups respectively
研究目的:通过测定泪液破裂时间来评价白内障术后泪液膜不稳定性。研究地点:本研究在巴基斯坦拉合尔拉合尔大学教学医院进行。材料与方法:采用描述性横断面研究方法，在北京大学附属教学医院进行。对白内障术后患者的泪液破裂时间进行了测量。采用非概率方便抽样技术，共纳入60例患者。研究对象包括年龄在45-65岁之间的男性和女性患者。数据通过自行设计的问卷形式收集。进一步的结果使用SPSS version 20进行分析。结果:两组患者术后1周、2周、1个月泪液破裂时间均明显缩短(P = 0.05)。0002年,P <。)。然而，术后1个月泪膜稳定性恢复到术前水平。术后结果的平均值与术前测量值不同。术后1周的BUT结果明显下降(P= 0.0001)，但术后1个月恢复到非常接近术前值。而杯状细胞密度(GCD)在术后1周、2周和1个月均显著降低(P< 0.0001)。结论:本研究认为白内障手术后由于杯状细胞的破坏，泪液破裂时间明显缩短，如上表所示。但分别随访1周、2周和1个月后，撕心裂肺时间明显改善
