Ocular injuries and eye care seeking patterns following injuries among cocoa farmers in Ghana
Background: The work environment of cocoa farmers exposes them to several ocular hazards that predispose them to eye diseases and injuries. However, the extent of ocular injuries and health seeking patterns following these injuries are unknown among cocoa farmers in Ghana.Objectives: To determine the prevalence of ocular injuries and health seeking behaviour following injury among cocoa farmers in Ghana.Methods: Five hundred and fifty six participants were recruited through simple random sampling using a multistage approach from four cocoa growing districts in Ghana. A structured questionnaire was used to collect relevant information such as demography, ocular hazards and injuries experienced. An ocular examination was also conducted to assess the eye health of the participants. Descriptive and regression statistics were used to analyze the data. The rate of ocular injuries was calculated by using the number of injuries reported that resulted in lost work time/days divided by the number of worker years at risk of injury (sum of years worked in cocoa farms for all the participants).Results: The rate of ocular injuries was 11.3/1000 worker years (95% CI: 9.4 - 31) which led to lost work time of 37.3/1000 worker years (95% CI: 34.1 - 40.8). The major causes of ocular injury were plants/branches (n=73, 51.1%), chemicals (n=27, 18.9%), cocoa pod/husk (n=14, 9.8%) and occurred mostly during weeding, harvesting and chemical spraying. Few (n=34, 6.1%) participants reported the use of ocular protection. Fifty-five (38.5%) participants visited the local chemical shops, while 37 (25.9%) visited hospitals/clinics for ocular treatment of their injuries.Conclusion: There is a high rate of ocular injuries among cocoa farmers who make insufficient use of appropriate eye care services. There is the need for eye health education among cocoa farmers in Ghana.Keywords: Ocular injuries, cocoa farmers, ocular protective device, eye care service
A situational analysis of eye care services in Swaziland
Compared to other African countries, Swaziland performs the worst in terms of providing eye health care services. A priority goal of the World Health Organization (WHO) is to alleviate childhood blindness, particularly in low-income countries such as Swaziland, where many people live in poverty, which is a contributor to poor health outcomes. A mixed method approach that entailed a document review, key informant interviews and clinical facility assessment questionnaires was used. Hospitals and mission clinics offering ophthalmic services were identified through the website of the Ministry of Health and verified during key informant interviews. A saturated sampling procedure was applied due to the few facilities that offer eye care services. Six framework components from the WHO for analysing health systems were utilised in an eye health care service context: leadership and governance, eye health services, eye health workforce, eye health financing systems, eye health medical supplies and technologies, and eye health information systems. Poor management, lack of accountability, poor monitoring and evaluation mechanisms, weak coordination and ineffective private-public sector regulations were identified as factors that lead to poor eye care in the country. The optometrists indicated that refractive services are the most rendered ophthalmic services. The exodus of healthcare practitioners has contributed to the downfall of the public health sector in the country. Five government eye care facilities, 3 government hospitals, 1 non-governmental organization (NGO) and a church mission clinic were included in this analysis. The eye services distribution favors the more affluent areas, particularly the more urban Hhohho Region, which is also where most of the eye health professionals are located. No campaigns have been conducted to prevent childhood blinding diseases or create awareness about getting children’s eyes tested for refractive correction. The burden of eye diseases among children in Swaziland remains unknown. More eye health care personnel and equipped facilities are needed throughout the country, and the eye health care program needs to be adopted
Ocular injuries and eye care seeking patterns following injuries among cocoa farmers in Ghana.
Background: The work environment of cocoa farmers exposes them to
several ocular hazards that predispose them to eye diseases and
injuries. However, the extent of ocular injuries and health seeking
patterns following these injuries are unknown among cocoa farmers in
Ghana. Objectives: To determine the prevalence of ocular injuries and
health seeking behaviour following injury among cocoa farmers in Ghana.
Methods: Five hundred and fifty six participants were recruited through
simple random sampling using a multistage approach from four cocoa
growing districts in Ghana. A structured questionnaire was used to
collect relevant information such as demography, ocular hazards and
injuries experienced. An ocular examination was also conducted to
assess the eye health of the participants. Descriptive and regression
statistics were used to analyze the data. The rate of ocular injuries
was calculated by using the number of injuries reported that resulted
in lost work time/days divided by the number of worker years at risk of
injury (sum of years worked in cocoa farms for all the participants).
Results: The rate of ocular injuries was 11.3/1000 worker years (95%
CI: 9.4 - 31) which led to lost work time of 37.3/1000 worker years
(95% CI: 34.1 - 40.8). The major causes of ocular injury were
plants/branches (n=73, 51.1%), chemicals (n=27, 18.9%), cocoa pod/husk
(n=14, 9.8%) and occurred mostly during weeding, harvesting and
chemical spraying. Few (n=34, 6.1%) participants reported the use of
ocular protection. Fifty-five (38.5%) participants visited the local
chemical shops, while 37 (25.9%) visited hospitals/clinics for ocular
treatment of their injuries. Conclusion: There is a high rate of ocular
injuries among cocoa farmers who make insufficient use of appropriate
eye care services. There is the need for eye health education among
cocoa farmers in Ghana. Keywords
Prevalence and causes of visual impairment amongst hearing impaired school-going children in sub-Saharan Africa: a scoping review
Background: Learners living with hearing impairment are at a higher risk of visual impairment.
Purpose: To summarise relevant literature investigating the prevalence and causes of visual impairment amongst learners living with hearing impairment in sub-Saharan Africa.
Methods: A search of nine databases and the reference lists of retrieved studies were conducted using the standard methodology for scoping reviews as described in the PRISMA statement. The databases were MEDLINE, PubMed, EMBASE, the Cochrane Library, Global Health, OVID, Google Scholar, Web of Science, and Science Direct. A scoping review of articles published in the English language from 2000 to 2020 was conducted while considering the study design, sub-Saharan Africa, and school for the deaf. Descriptive statistics was used to analyse the data.
Results: The initial search retrieved eight studies, seven of which met the set inclusion criteria. All seven studies included employed a cross-sectional design. The prevalence of visual impairment ranged from 2.2-34.6% with the major cause being uncorrected refractive error (7.9-73.26%). The most common type of refractive error was myopia (42.2%) followed by hyperopia (28.6%) and astigmatism (28.6%).
Conclusion: This review has demonstrated that there is a paucity of high-quality and well-designed studies that have investigated the prevalence and causes of visual impairment amongst hearing-impaired children in sub-Saharan Africa suggesting the need for further research in this area.

Validation and use of quality of life impact of refractive correction questionnaire in spectacle wearers in Malawi:A clinic-based study
BACKGROUND: To assess the psychometric properties of the QIRC questionnaire and use it as an outcome measure in spectacle wearers attending an eye clinic in Malawi. METHODS: Participants who had uncorrected distance visual acuity of below 6/18 and improved to 6/9 or better with spectacles on both eyes were included in the study. The participants self-administered the Chichewa version of the QIRC questionnaire that was translated and culturally adapted for Malawian settings. Psychometric evaluation of the QIRC responses was carried out using the WinSteps software (Version 3.92.1; Winsteps, Chicago, IL) by applying the Andrich rating scale model of the Rasch analysis. RESULTS: One hundred and forty-three participants (mean age ± standard deviation, 27.64 ± 2.91; age range; 16 to 39 years; male, 51.7%) completed the QIRC. The Chichewa QIRC had satisfactory psychometric properties (Ordered response categories, Person separation index, 1.93; Item separation index, 3.42; Targeting 0.70) including excellent Rasch-model fit statistics (Infit and Outfit MnSq 0.05 for all). The QIRC scores negatively correlated with uncorrected visual acuity (in logMAR) in the better eye (spearman's rho=−0.34, p < 0.001). CONCLUSION: The translated and culturally adapted version of the QIRC Questionnaire had satisfactory psychometric properties to measure the refractive error-specific quality of life in Malawi. It performed well as an outcome measure of spectacle wear
Acceptance of COVID-19 vaccine among sub-Saharan Africans (SSA): a comparative study of residents and diasporan dwellers
Background: The COVID-19 vaccines are being rolled out across all the sub-Saharan Africa (SSA) countries, with countries setting targets for achieving full vaccination rates. The aim of this study was to compare the uptake of, resistance and hesitancy to the COVID-19 vaccine between SSA locally residents and in the diasporan dwellers. Methods: This was a cross-sectional study conducted using a web and paper-based questionnaire to obtain relevant information on COVID-19 vaccine acceptance. The survey items included questions on demography, uptake and planned acceptance or non-acceptance of the COVID-19 vaccines among SSAs. Multinomial logistic regression was used to determine probabilities of outcomes for factors associated with COVID-19 vaccination resistance and hesitancy among SSA respondents residing within and outside Africa. Results: Uptake of COVID-19 vaccines varied among the local (14.2%) and diasporan (25.3%) dwellers. There were more locals (68.1%) who were resistant to COVID-19 vaccine. Participants’ sex [adjusted relative risk (ARR) = 0.73, 95% CI: 0.58 – 0.93], education [primary/less: ARR = 0.22, CI:0.12 – 0.40, and bachelor’s degree: ARR = 0.58, CI: 0.43 – 0.77]), occupation [ARR = 0.32, CI: 0.25—0.40] and working status [ARR = 1.40, CI: 1.06—1.84] were associated with COVID-19 vaccine resistance among locals. Similar proportion of local and diasporan dwellers (~ 18% each) were hesitant to COVID-19 vaccine, and this was higher among health care workers [ARR = 0.25, CI: 0.10 – 0.62 and ARR = 0.24, CI:0.18—0.32, diaspora and locals respectively]. After adjusting for the potential confounders, local residents aged 29–38 years [ARR = 1.89, CI: 1.26—2.84] and lived in East Africa [ARR = 4.64, CI: 1.84—11.70] were more likely to report vaccine hesitancy. Knowledge of COVID vaccines was associated with hesitancy among local and diasporan dwellers, but perception was associated with vaccine resistance [ARR = 0.86,CI: 0.82 – 0.90] and hesitancy [ARR = 0.85, CI: 0.80 – 0.90], only among the local residents. Conclusions: Differences exist in the factors that influence COVID-19 vaccine acceptance between local SSA residents and thediasporan dwellers. Knowledge about COVID-19 vaccines affects the uptake, resistance, and hesitancy to the COVID-19 vaccine. Information campaigns focusing on the efficacy and safety of vaccines could lead to improved acceptance of COVID-19 vaccines
Do National Senior Certificate (NSC) results predict first year optometry students’ academic performance at university?
Matriculation results have previously been used as reasonable predictors of first-year academic performance at university. Although there have been some improvements in access to education for many South Africans, the quality of the National Senior Certificate (NSC) introduced in 2008 remains uncertain. The purpose of this study is to determine whether matriculation subjects’ scores can be predictors of academic success in the first year of the Bachelor of Optometry (BOptom) programme. The files of eighty four optometry students who wrote the NSC examinations from 2009-2011 were reviewed and the matriculation scores were recorded. These scores were compared to their results in modules in their first year BOptom programme. There was a weak correlation between matriculation and first year optometry results. Overall, the matriculation scores showed a weak correlation with the first semester average and overall first year marks. The NSC matriculation scores cannot be used as sole predictors of success in the first year of the BOptom programme
The impact of spectacle correction on the well-being of children with vision impairment due to uncorrected refractive error: a systematic review
Abstract Background Despite being easily corrected with eyeglasses, over two-thirds of the world’s child population presents with vision impairment (VI) due to uncorrected refractive errors. While systematic reviews have shown that VI can significantly impact children’s depression and anxiety, none have reviewed the existing literature on the association between spectacle correction and well-being. This review aims to address this knowledge gap. Main outcome measures The main outcome measures were i) cognitive and education well-being which included mathematics and english literacy, reading fluency, school function, academic performance and grades; ii) psychological and mental health well-being which included physical anxiety, learning anxiety and mental health test scores and iii) quality of life. Methods We searched eight databases for articles published between 1999 to 2021 that assessed the associations between spectacle correction and children’s (0 to 18 years) well-being. There were no restrictions on language or geographic location. Two reviewers independently screened all publications using validated quality checklists. The findings of the review were analysed using narrative synthesis. [PROSPERO CRD42020196847]. Results Of 692 records found in the databases, six randomised control trials, one cohort, one cross-sectional and one qualitative study (N = 9, 1.3%) were eligible for analysis. Data were collected from 25 522 children, 20 parents and 25 teachers across the nine studies. Seven were rated as good quality (67 to 100% of quality criteria fulfilled), and two were satisfactory (33 to 66% of quality criteria fulfilled). Spectacle correction was found to improve children’s educational well-being (n = 4 very strong evidence; n = 2 strong evidence), quality of life (n = 1, very strong evidence) and decrease anxiety and increase mental health scores (n = 1, strong evidence). Conclusion Evidence suggests that spectacle correction improves children’s cognitive and educational well-being, psychological well-being, mental health, and quality of life. More research is needed, given the paucity of published literature and the focus on only three aspects of well-being
Demographic factors associated with myopia knowledge, attitude and preventive practices among adults in Ghana: a population-based cross-sectional survey
Abstract Purpose Knowledge, positive attitude and good preventive practices are keys to successful myopia control, but information on these is lacking in Africa. This study determined the KAP on myopia in Ghana. Methods This was a population-based cross-sectional survey conducted among adults (aged 18 years and older) living across 16 regions of Ghana between May and October 2021. Data on socio-demographic factors (sex, age, gender, level of education, working status, type of employment, monthly income, and region of residence), respondents’ awareness, and knowledge, attitude and preventive practices (KAP) about myopia were collected. Composite and mean scores were calculated from eleven knowledge (total score = 61), eight attitude (48), and nine preventive practice items (33). Differences in mean scores were assessed using one-way analysis of variance (ANOVA) and standardized coefficients (β) with 95% confidence intervals (CI), using multiple linear regression to determine the associations between the dependent (KAP) and demographic variables. Results Of the 1,919 participants, mean age was 37.4 ± 13.4 years, 42.3% were aged 18–30 years, 52.6% were men, 55.8% had completed tertiary education, and 49.2% had either heard about myopia, or accurately defined myopia as short sightedness. The mean KAP scores were 22.9 ± 23.7, 33.9 ± 5.4, and 22.3 ± 2.8, respectively and varied significantly with many of the demographic variables particularly with age group, region, marital status, and type of employment. Multiple linear regression analyses revealed significant associations between region of residence and knowledge (β =—0.54, 95%CI:-0.87, -0.23, p < 0.001), attitude (β =—0.24, 95%CI:-0.35,-0.14, p < 0.001) and preventive practices (β = 0.07, 95%CI: 0.01, 0.12, p = 0.015). Preventive practices were also associated with type of employment (self-employed vs employee: β = 0.25, 95%CI: 0.15, 4.91, p < 0.05). Knowledge scores were significantly higher in those who lived in the Greater Accra (39.5 ± 18.5) and Eastern regions (39.1 ± 17.5) and lower among those who lived in the Upper West region (6.4 ± 15.6). Government employees and those with tertiary education had significantly higher mean knowledge scores compared with non-government employees (β = 4.56, 95%CI 1.22, 7.89, p = 0.007), and those with primary/no education (β = 18.35, 95%CI: 14.42, 22.27, p < 0.001). Conclusion Ghanaian participants had adequate knowledge of myopia but showed poor attitude and low preventive practices, which varied significantly between regions and were modified by socio-demographic factors. Further research into how education can be used to stimulate Ghanaians’ engagement in preventive practices is needed
