Awareness and knowledge of glaucoma and associated factors among adults: a cross sectional study in Gondar Town, Northwest Ethiopia

Abstract Background Raising public awareness and knowledge about glaucoma is a key for early case identification and prevention of blindness. However, awareness and knowledge about glaucoma is unknown at community level, making provision of interventions difficult. This study was intended to assess the awareness and knowledge of adults about glaucoma and the factors affecting it in Gondar town, Northwest Ethiopia. Methods Community based cross - sectional study was conducted on 701 adults 35 and above years in Gondar from April 12–30, 2016. Multistage sampling technique was used to select study participants. Interviewer administered pretested structured questionnaire was used to collect data after verbal informed consent. Data were entered into EpiData version 3.1 and analyzed by Statistical Package for Social Sciences version 20. Bivariate and multivariate logistic regression models and Odds ratio with 95% interval were used to identify factors. P–value <0.05 was considered statistically significant. Results Seven hundred one adults age 35 and above years were participated with a response rate of 99.3%. The male to female ratio was 1:1.6 with median age of 48 years with interqurtile range of 20. The proportion of awareness was 35.1% (95% CI: 31.5%, 38.6%). Good knowledge was demonstrated in 49.6% (95%CI: 43.3%, 55%) of glaucoma aware participants. Education (primary [AOR: 3.21; 1.73, 5.95], secondary [AOR: 4.34; 2.30, 8.22]; college and above [AOR: 9.82; 4.27, 22.60]) and having eye examination [AOR: 2.78; 1.86, 4.15] were positively associated with awareness of glaucoma whereas older age (65 –74 years [AOR: 0.31(0.21, 0.76]) was inversely related. Level of Education (primary[AOR:2.83;1.04,7.71],secondary[AOR:3.45;1.33,9.41],college and above [AOR: 4.86;1.82,12,99] and having eye examination [AOR: 2.61;1.53,4.45] were significantly associated with knowledge. Conclusion The study has indicated higher level of awareness and knowledge about glaucoma in urban communities than previous studies. It has also identified educational status, eye examination at least once in life are related with better awareness and knowledge. The present awareness and knowledge should be enhanced through public oriented glaucoma education via mass media and incorporating eye check up as a routine in older people

Visual Impairment among Primary School Children in Gondar Town, Northwest Ethiopia

Background. An impairment of the visual system at or shortly after birth adversely affects educational performance of children which typically occurs through vision. Limited evidence on the magnitude and causes of visual impairment is one of the reasons for the low priority given to eye care in low-income countries. Objectives. To estimate the prevalence and determine the causes of visual impairment in primary school children in Gondar town, Northwest Ethiopia. Materials and Methods. A descriptive cross-sectional study was conducted among 1289 children aged 5–15 years who were randomly selected in 9 primary schools (government and private) from May to June 2016. Visual acuity was measured at 6 m using Snellen’s chart, and children with an acuity of less than 6/18 in the better eye underwent refraction and a detailed eye examination. A cause of their impairment was determined. Data were recorded using pretested tools. . Statistical Package for Social Sciences version 16 was used to enter and analyze the data using 95% confidence intervals. Results. The prevalence of visual impairment was 1.8%. Refractive errors (nearly 70%) followed by strabismus and cataract, each contributing 4.3%, were the most frequent causes of visual impairment in the study population. Majority (87%) of the children had moderate degree of vision impairment, and 10–15-year age groups are the more affected ones. Children of age fifteen and above showed statistically significant association with visual impairment (p=0.005). Conclusion. The magnitude of visual impairment in primary school children in the study area is significant. School screening programme is recommended to minimize the burden of visual impairment in the study area

Vision-Related Quality of Life among Adult Patients with Visual Impairment at University of Gondar, Northwest Ethiopia

Purpose. The purpose of this study was to assess vision-related quality of life and associated factors among adult patients with visual impairment at the University of Gondar Tertiary Eye Care and Training Center, Northwest Ethiopia. Methods. The institution-based cross-sectional study was conducted from April 24 to May 12, 2017, at the University of Gondar Tertiary Eye Care and Training Center among 484 patients with visual impairment. Pretested, structured National Eye Institute Visual Function Questionnaire-25 was used to collect data by interviewing. Data were entered using EPI-INFO version 3.5.1 and analyzed with SPSS version 20. Binary logistic regression was used to determine factors associated with vision-related quality of life. Variables with p value 75 years (AOR = 1.87 (95% CI: 1.02–3.40)), rural residency (AOR = 1.71 (95% CI: 1.13–2.60)), severe visual impairment/blindness (AOR = 2.76 (95% CI: 1.80–4.23)), and history of visual impairment longer than 3 years (AOR = 2.85 (95% CI: 1.61–5.04)) had statistically significant association with poor vision-related quality of life. Conclusion. Almost half of the patients with visual impairment had poor vision-related quality of life. Severe visual impairment/blindness, long duration of visual impairment, older age, and rural residency had a statistically significant association with poor vision-related quality of life
