“…This result confirms that the difficulties of visual impairment increase with the severity of glaucoma. This finding is in line with the study done in Ethiopia [24]. This may be due to the study population with relatively similar age ranges (� 17 years) and the use of a similar cut-off point for defining visual impairment.…”

Background Diabetes mellitus is a complex metabolic disorder characterized by hyperglycemia that results from defects in insulin secretion, insulin action, or both. Glaucoma is the ocular complication of diabetic illness. In addition to this, retinopathy, maculopathy, ischemic optic neuropathy, extra-ocular muscle palsy, iridocyclitis, and rubeosis iridis were other complications. This study aims to determine the impact of diabetes on visual impairment and blindness among diabetic patients in Ethiopia. Methods This hospital-based cross-sectional study includes 401 samples of diabetic patients in the University of Gondar Comprehensive Specialized Hospital from January 2017 to January 2019. The multinomial logistic regression model was employed to identify significant differences among the factor variables. Results The magnitude of blindness was 32.17%, and the burden of severe visual impairment was 12.46%. Of the total patients, 120(29.9%) were have diabetic retinopathy of whom, 113(94.2%) were blind either in the right, left, or both eyes and 3 (2.5%) had severe visual impairment. One hundred twenty-six (31.42%) patients developed diabetic maculopathy of whom, 117 (92.85%) were blind either in the right or left eye, and one (0.8%) had severe visual impairment. From the whole diabetic patients, the magnitude of glaucoma was 186(46.38%), and from the patients who developed glaucoma was blind visual impairment 127(68.27%) either in the right or left eye. Thirty-eight (20.34%) had severe visual impairment. Glaucoma was significantly associated with severe visual impairment and blindness (p<0.001). Glaucoma, diabetic retinopathy, maculopathy, and type of diabetes are factors for visual impairment. Conclusion We found that visual impairment in the category of severe and blindness are frequent in Ethiopian diabetic patients. Glaucoma, diabetic retinopathy, maculopathy are the main predictive factors that determine the occurrence of blindness.

“…Consistent with the studies conducted in South Africa [ 35 ], Taiwan [ 36 ], Ghana [ 37 ], and Ethiopia [ 24 ], in this study, those women aged 31–49 years had higher odds of VI. This could be due to the increased risk of age-related diseases of the eye following ageing.…”

“…According to the previous studies in the globe, VI has a cross relation with the age of pregnant women [ 1 , 14 , 15 ], residence [ 1 , 16 ], educational status [ 17 – 19 ], occupation [ 20 , 21 ], gestational age (GA) [ 7 , 15 , 22 ], maternal parity [ 15 , 20 , 23 ], diabetes mellitus [ 24 , 25 ], gestational diabetes mellitus (GDM) [ 14 , 20 ], pre-existing hypertension [ 12 , 20 ], pregnancy-induced hypertension (PIH) [ 14 , 20 ], family history of vision problem [ 26 ], prolonged use of smart phones and computers [ 27 – 29 ], medication history [ 14 , 30 , 31 ], and history of contraceptive use [ 14 , 32 ].…”

Background Visual impairment is a major public health concern among women of reproductive age groups in Ethiopia, which is getting worse during pregnancy. Though visual impairment has lots of serious consequences across the life course of pregnant women, there is no previous study on this topic in Ethiopia. Thus, this study determined the prevalence of visual impairment and identified associated factors among pregnant women attending antenatal care units at the governmental health institutions in Gondar City Administration, Northwest Ethiopia. Methods An institution-based cross-sectional study was conducted. A systematic random sampling technique was used to recruit the study participants. We used an interviewer-administered questionnaire comprising of socio-demographic, clinical and pregnancy-related variables to collect the required data. Snellen’s illiterate “E” chart was used to determine visual impairment. EpiData 3 and Stata 14 were used for data entry and statistical analysis, respectively. Both bivariable and multivariable binary logistic regression analyses were executed to identify associated factors of visual impairment. Variables with a p-value ≤0.05 in the multivariable logistic regression analysis were declared as statistically significant with visual impairment. Results A total of 417 (response rate = 98.6%) participants were involved in this study, with a median age of 27 years. The overall prevalence of visual impairment was 22.5% (95% CI: 18.5–26.6). Thirty (7.2%) and thirty-two (7.7%) of the study participants had moderate to severe visual impairments in their right and left eyes, respectively. Participants aged from 31 to 49 years (AOR = 2.1; 95% CI: 1.1–4.0), being 3rd trimester (AOR = 2.4; 95% CI: 1.3–4.5), multi & grand multipara (AOR = 2.3; 95% CI: 1.2–4.6), and history of contraceptive use (AOR = 2.7; 95% CI: 1.2–6.3) had higher chance of visual impairment. Conclusion The magnitude of visual impairment among pregnant women was high in the study area. Therefore, routine screening and evaluation of pregnant women for visual condition during antenatal care visits is recommended. Further investigations of visual changes, particularly as a result of pregnancy, are warranted.

“…In this hospital-based study, the prevalence of VI was 28.5% of the whole patients attending eye clinics during January-December 2017. This was higher than the prevalence reported by Binnawi et al [17] in North Kordofan State of Sudan (8.37%) and by Assefa et al [18] in Ethiopia (16.8%). The high rate of visual impairment may be principally attributed to the difference in study design, environmental differences, the age range of participants, gender differences, and sample sizes.…”

Abstract: BACKGROUND: The World Health Organization (WHO) states that visual impairment (VI) is a reduction of vision functions due to eye diseases, trauma, and congenital eye conditions. Current estimates indicate that more than 90% of people with vision impairment live in rural and developing countries. AIM: This study aimed to determine demographic characteristics and causes of visual impairment in the White Nile State of Sudan METHODS: A cross-sectional retrospective hospital-based study, including all patients attending Kosti and Rabak eye hospitals from January to December 2017, was conducted. A total of 1000 records were reviewed, 300 of them met the required criteria and then included in this study, with a mean age of 59.8 ± 18.5 (ranging from 10 to 95) years old. Visual impairment was classified according to the International Classification of Diseases, 11th revision, 2018 (ICD-11). RESULTS: The prevalence of VI was found at 28.5 %. Based on best-corrected visual acuity (BCVA), 6 participants (2.0%) were mild VI, 32 (10.7%) had moderate VI, 152 (50.7%) had severe VI, and 110 (36.7%) were blind. VI was associated with patients' age in children (3.6%) and reached (48.3) in older age (P=0.001). VI was more common among males 158 (52.7%) than females but was statistically not significant (P=0.35). The main causes of VI were cataract (52%), refractive errors (20.7%), glaucoma (16.3%), corneal disorders (5.3%), diabetic retinopathy (1.7 %), and other causes (4%). Conclusion Visual impairment was high in the community and more prevalent among older age. Cataract was the leading cause of VI, then refractive errors and glaucoma. Among children, uncorrected refractive errors and cataracts were the common leading causes of VI. In adults, the main causes were cataracts, uncorrected refractive errors, and glaucoma.
