BackgroundIn Ethiopia, there is a substantial mismatch between need and supply of corneal transplant. Although corneal transplantation service is affected by various factors, willingness to donate eyes is an essential indicator of its availability, accessibility, and acceptability. Therefore, this study aimed to determine the magnitude of willingness to donate eyes and its associated factors, which help to develop appropriate strategies that can address this undersupply and unmet need.MethodsA community-based cross-sectional survey was conducted on 774 adults who were selected using multistage random sampling in Gondar town, North West, Ethiopia. The data were collected through interviews.ResultsIn this survey, 774 adults with a median age of 30 ± 14.33 years participated. The proportion of willing to donate eyes was 37.6% [95% CI: 34.3%–41.3%]. It was positively associated with the religious belief of Christianity [AOR = 1.73, 95% CI: 1.08–2.75], having awareness about eye donation [AOR = 1.38, 95% CI: 1.01–1.92], educational level of high school [AOR = 2.90, 95% CI: 1.72–4.90], and College/University [AOR = 2.23, 95% CI: 1.28–3.87].ConclusionThe magnitude of willingness to donate eyes was moderate and positively associated with the higher educational level and awareness. It is, therefore, strategic to plan awareness creation programs to mobilize the community.Electronic supplementary materialThe online version of this article (10.1186/s12886-017-0577-1) contains supplementary material, which is available to authorized users.

Background Diabetic retinopathy is the most common microvascular complication of diabetes mellitus on eye and it is the leading cause of visual impairment among productive segment of the population. Globally, the prevalence of diabetic retinopathy is reported to be 27%. In Ethiopia, sufficient data is lacking on the prevalence of diabetic retinopathy as well as information on its predisposing factors. The study was required to assess the prevalence of diabetic retinopathy and its predisposing factors in diabetic patients attending at a General Hospital in Ethiopia. Methods An institution based cross sectional study was employed on 331 diabetic patients recruited with a systematic random sampling technique. Data were collected through structured questionnaire, tracing patients’ medical folder and ocular health examination. Data were analyzed with Statistical Package for Social Science Version 20. Logistic regression methods of analysis were used to figure out predisposing factors of diabetic retinopathy. Adjusted odds ratio with 95% confidence interval was used to determine the strength of association. Result A total of 331 diabetic patients completed the study with a response rate of 99.10%. The median duration of diabetes was 5 years. The prevalence of diabetic retinopathy was 34.1% (95%Confidence Interval (CI): 28.7%-39.3%). Low family monthly income (Adjusted Odds Ratio (AOR) = 7.43, 95% CI: 2.44–22.57), longer duration of diabetes (AOR = 1.44, 95% CI: 1.30–1.58), poor glycemic control (AOR = 4.76, 95%CI: 2.26–10.00), and being on insulin treatment alone (AOR = 3.85, 95%CI: 1.16–12.74) were independently associated with diabetic retinopathy. Conclusion and recommendation The prevalence of diabetic retinopathy was 34.1%, higher than national and global figures. Low family monthly income, longer duration of diabetes, poor glucose control and being on insulin treatment alone were important risk factors of diabetic retinopathy. Proper diabetes self management and early screening of diabetic retinopathy in all diabetic patients were recommended.

Background Routine eye examination plays a vital role in detecting diabetic retinopathy in its earliest stage before the onset of blindness. Patients’ knowledge about the nature and the consequences of diabetic retinopathy and routine eye checkup helps for timely identification and early treatment. However, there is limited evidence on knowledge of patients with diabetes mellitus on diabetic retinopathy and their eye check-up practices in Ethiopia. The aim of this study was to assess knowledge about diabetic retinopathy, eye check-up practice and associated factors of diabetic retinopathy among adult diabetic patients at Debark hospital, Northwest Ethiopia. Methods Institution based cross-sectional study was conducted at Debark hospital, Northwest Ethiopia, from April 20/2018- May 20/2018. A pretested interviewer administered structured questionnaire was used to collect data among 230 diabetic patients aged 18 years and above. Data were entered in to Epi Info version 7 and exported to SPSS version 20 for analysis. Bivariable and multivariable binary logistic regression analyses were done. Odds ratio with 95% confidence level was determined and variables with p–value of < 0.05 were considered as statistically significant. Result Out of 238 sample 230 were participated, among this, 119 (51.7%) were males. The mean age of the respondents was 49 (SD ±17.6) years. One hundred nine (47.4%) participants had good knowledge and 91 (39.6%) had good eye check-up practice. Urban residence [AOR = 2.65;95% CI: 1.16–6.07)]), monthly income of 3501–8000 birr [AOR = 4.54;(1.31–15.7)], type II diabetes mellitus [AOR = 3.9;(1.6–9.6)], duration of diabetes (6–12 years [AOR = 4.4;(1.4–13.5)]), history of eye disease [AOR = 5.5;(2.3–13.0)] were associated with good knowledge. Similarly, longer duration of diabetes (13–25 years [AOR = 3.77; (1.05–13.5)]) and history of eye disease [AOR = 2.47; (1.09–5.62)] were associated with good eye check-up practice. Conclusion The proportion of good knowledge about diabetic retinopathy among diabetic patients at Debark hospital was fair (47.4%) and good eye check-up practice (eye examination at least once in the past year) was low (39.6%). Longer duration of diabetes and history of eye disease were identified as positive factors for good knowledge and eye check-up practice. Knowledge and regular eye check-up practice needs to be enhanced through provision of appropriate health education.

Introduction: Vision-threatening diabetic retinopathy, a long-term microvascular complication of diabetes in the eye, is a major cause of blindness worldwide. Sleep is regulated by a special area of the brain, and poor quality of sleep has been implicated in long-term diabetic complications, including diabetic retinopathy. The study was aimed at exploring whether poor sleep quality is associated with the likelihood of developing vision-threatening diabetic retinopathy. Methods: A matched case-control study was conducted from 6 May 2022 to 6 September 2022. The study was based on patients with diabetes (both type 1 and type 2), attending a retina clinic of the referral center. Patients with confirmed vision-threatening diabetic retinopathy were defined as cases and matched with control study subjects. Rating of sleep quality was done by Pittsburgh Sleep Quality Index assessment tool. Conditional logistic regression model was applied to assess the effect of overall poor sleep quality on vision-threatening diabetic retinopathy. Results: The study recruited a total of 126 (63 duration-matched pairs) patients with diabetes. The overall quality of sleep was poor among 71.90% of patients in the case groups, significantly higher compared with those of the control groups (28.10%) (p \ 0.00). The mean quality of sleep for cases [mean (M) = 7.10, standard deviation (SD) = 4.30] was higher than the control group (M = 3.60, SD = 2.70). The magnitude of the difference [M difference = 3.50, 95% confidence interval (CI): 2.25-4.75] was significant. Poor sleep quality predicted the chance of developing visionthreatening diabetic retinopathy in a diabetic cohort.Conclusions: This study revealed a significant association between the overall poor quality of sleep and vision-threatening diabetic retinopathy. Co-management of sleep disruption and vision-threatening diabetic retinopathy, and better sleep advisory are warranted.
