BackgroundLow vision and blindness are major public health problems. A vast burden of worlds visually impaired live in low-income settings especially in sub Saharan Africa. In such settings the blindness is associated with considerable disability and excess mortality, resulting in huge economic and social consequence. The main purpose of this study was to determine the prevalence and associated factors of low vision and blindness among patients at St. Paul’s hospital millenium medical college.MethodsInstitution based cross sectional design study was carried out from January to April, 2017 with sample size of 904. Systematic random sampling was used to recruit the study subjects. Retrospective medical chart review was done; data was entered into and analyzed by SPSS 23. Descriptive statistics such as frequency cross tabulation and chi-square test was carried out to translate data into information. P-value less than 0.05 was considered as statistically significant.ResultsA total of 881 subjects with a response rate of 97.4% selected. The mean age of the study subjects was 44.53(SD: ± 21.85) with a range of 1–100 years. The prevalence of low vision and blindness was 91 (10.3% (95% CI: 8.2, 12.3)), and 64 (7.3 95%CI: 5.7, 9.0)) respectively. Age (p-value < 0.001), cataract (p-value = 0.002), glaucoma (p-value = 0.002) and age related macular degeneration (p-value < 0.001) were significantly associated with low vision and blindness.ConclusionLow vision and blindness found in this study was high. Age, cataract, glaucoma and age related macular degeneration were significantly associated with low vision and blindness. This amount of magnitude will be reduced if prevention, early diagnosis and management will be targeted towards avoidable causes of visual impairment.
Background: Glaucoma is a global public health problem and it is the leading cause of irreversible blindness worldwide. Even though public knowledge of glaucoma is a key for early case identification and prevention of blindness, it is unknown in the study area, making provision of interventions difficult. Therefore, this study was intended to assess knowledge of glaucoma and associated factors among adults in Gish Abay town, Northwest Ethiopia, 2018. Methods: A Community based cross-sectional design study with systematic random sampling technique was used to select 630 adults. The study was conducted from April to May, 2018. Data was entered into Epi Info version 7 and was analysed by Statistical Package for Social Sciences version 23. Binary logistic regression model and adjusted odds ratio with 95% confidence level was used to identify the significant factors associated with knowledge of glaucoma. Variables with P-value ≤0.05 was considered statistically significant. Results: About 594 adults were participated with a response rate of 94%. Above half of (52%) the participants were females with median age of 28 years. The proportion of good knowledge was demonstrated in 16.8% [95% CI; 14.0, 19.9]. Educational status: primary education [
Purpose: The aim of this study was to assess the prevalence and associated factors of pterygium among adults in Kolla Diba town, Northwest Ethiopia, 2019. Method: A community-based cross-sectional study was done in Kolla Diba town from May 30-June 16, 2019. A systematic random sampling technique was used to select 627 study participants. Data was collected through basic ophthalmic examination with a portable slit lamp, 3x magnifying loop and torchlight and a pretested structured questionnaire were administered to collect the data. Then the data entered into EPI INFO version 7 and analyzed using SPSS version 20. Descriptive statistics and binary logistic regression analysis were employed. P-values of <0.05 were considered statistically significant. Result: A total of 605 study participants were involved with a response rate of 96.5%. Among them 317 (52.4%) participants were males. The mean age of the respondents was 38.18 +/- 15.56 with a range of (18-95) in years. The overall Prevalence of pterygium among adults living in Kolla Diba town was 112 (18.5% (95% CI (15.6- 21.7)). Being widowed (AOR = 7.32 (95%CI: 2.88, 18.57)), outdoor occupation (AOR = 2.50 (95%CI: 1.46, 4.29)), sun exposure (AOR = 2.38 (95%CI: 1.28, 4.43)), wind exposure (AOR = 1.97 (95%CI: 1.04, 3.72)), alcohol drinking (AOR = 2.26 (95%CI: 1.48, 4.63)), and severe blepharitis (AOR = 2.45 (95%CI: 1.48, 4.05)) had statistically significant positive association with pterygium. Conclusion: The prevalence of pterygium was relatively higher. Marital status (being widowed), outdoor occupation, sun exposure, wind exposure, alcohol drinking, and severe blepharitis were significantly associated with the development of pterygium.
Background: Cataract is the leading cause of avoidable blindness globally and in Africa. Various barriers limit access of cataract blind individuals to cataract surgery. This study aimed to determine the barriers to cataract surgery utilization among cataract blind patients presenting to campaign sites in Ethiopia. Methods: An institution-based cross-sectional design study was conducted to select 209 patients. The study was conducted from July to August 2020. A structured questionnaire was used to collect socio-demographic data and barriers for not having cataract surgery. Physical examination such as visual acuity, slit lamp bio microscopy and direct ophthalmoscopy was done for all participants. Epi Info 7 was used for data entry and Statistical Package for Social Science/SPSS version 23 was used for analysis after data were exported. Descriptive methods were employed for analysis. Results: A total of 209 subjects were recruited in the study with a mean age of 64.2 (±14.6) years, with a range of 32-99 years. From the total study subjects, 53% were males and 40.2% were over 66 years old. Upon presentation to the campaign site, 33% of study subjects had visual acuity of operable eye under blindness category and half of the study subjects (50.2%) had mature cataract. The most reported barriers were waiting until cataract becomes mature (18.7%), fear of surgery complications (16.7%), far from eye health institution (16.4%) and lack of income/cost for surgery (11.5%). Conclusion:Recognizing the severity and the blindness burden of cataract in Ethiopia, creating public awareness, establishing eye health institutions, increasing the number of eye health professionals, increasing the quantity and the quality of cataract campaigns to alleviate these barriers are of paramount importance at the country level.
Purpose: The purpose of this study was to determine the awareness of glaucoma and associated factors among adults living in Gish Abay town, Northwest Ethiopia. Methods: A population-based cross-sectional study was conducted on 594 adults who were selected using systematic random sampling from April to May 2018. Data were entered into Epi Info version 7 and were analyzed by SPSS version 23. Binary and multivariable logistic regression was used to determine factors associated with awareness. Variables with P-value < 0.05 were considered statistically significant. Results: The proportion of awareness of glaucoma was 24.4% [95% CI; 21.0, 28.
