Prevalence and Pattern of Ocular Morbidity among School Children in Southern Ethiopia
BACKGROUND፡ Visual health is linked to school achievement, quality of life and productivity. But eye screening in school children is not routinely done in most Ethiopian schools. This study was done to determine prevalence and pattern of ocular morbidity among school children in Roman Dega-Kedida,Southern Ethiopia.METHOD: This was a cross-sectional study. All children aged 16 years or less, attending the school during the study period were included. Data entry and statistical analyses were performed using SPSS Version 16. A P - value of < 0.05 was considered statistically significant.RESULT: A total of 778 children participated in this study. The female to male ratio was 1.06:1. The mean age was 11.34(±2.31) years. A total of 201 (25.8%) children had ocular morbidities. The most common was trachoma found in 85(10.9%). Of these, 49(56.5%) had active trachoma, while 37(43.5%) had either trachoma scar or trachomatous trichiasis. Allergic conjunctivitis was found in 49(6.3%), refractive error in 37(4.8%), and xerophthalmia in 17(2.2%) children. Visual impairment in one or both eyes was found in 41(5.3%) children. Thirty-two children (4.1%) had bilateral Visual impairment of which 6(18.8%) had moderate to severe visual impairment. The cause of visual impairment was refractive error in 37(90.2%), corneal opacity in 3(7.3%) and cataract in 1(2.4%) child.CONCLUSION: Most of the ocular diseases observed were either preventable or treatable. Health education to the community and establishing regular school screening program is recommended
Assessment of Risk Factors for Advanced Open Angle Glaucoma Presentation among Patients Visiting Jimma University Medical Center, Jimma, Ethiopia
Background: Glaucoma is the predominant cause of irreversible blindness, particularly the late presentation. The purpose of this study is to identify the risk factors associated with late presentation in Jimma University Medical Center
Methods: A case-control study was done among patients newly diagnosed to have open angle glaucoma (of any type) at Jimma University Medical Center from July 2014 – January 2019. Cases were patients/eyes diagnosed to have any type of open angle glaucoma with advanced glaucomatous disc features, whereas controls were patients diagnosed with early and moderate stages of glaucoma.
Results: There were 205 (116 cases and 89 controls) participants. The mean age of the participants at the time of diagnosis was 58.3±13.4yrs. Family history of blindness, presenting IOP, type of glaucoma and age were independently associated with late presentation. Patients with family history of blindness had late advanced glaucoma five times higher than those with no family history of blindness. The presence of late glaucoma among patients with presenting intra ocular pressure < 30mmHg is lower than those having ≥30mmHg (Adjusted Odds Ratio= 0.136). Primary open- angle glaucoma patients were less likely to present with advanced glaucoma than pseudoexfoliative glaucoma patients (Adjusted Odds Ratio=0.39). The chance of presenting with late glaucoma was increased by 3.4% for every one year increment of age.
Conclusions: Presence of family history of blindness, high presenting intraocular pressure, pseudoexfoliative glaucoma and old age are risk factors for late presentation of glaucoma.

Drought tolerant maize for farmer adaptation to drought in sub-Saharan Africa: Determinants of adoption in eastern and southern Africa
In sub-Saharan Africa (SSA), “maize is life,” due to its importance to food security and economic wellbeing. Around 40% of Africa’s maize-growing area faces occasional drought stress, resulting in yield losses of 10–25%. Around 25% of the maize crop suffers frequent drought, with losses of up to half the harvest. To reduce vulnerability and improve food security, the Drought Tolerant Maize for Africa (DTMA) project has made releases of 160 drought tolerant (DT) maize varieties between 2007 and 2013. These have been tested in experimental and farmers’ fields, and disseminated to farmers in 13 African countries through national agricultural research systems and private seed companies. Yields of the new varieties are superior to those of currently available commercial maize varieties under both stress and optimum growing conditions. Although the benefits of DT maize for African farmers have been repeatedly predicted, realization of those benefits depends on farmer uptake, which has received limited empirical study. We use new plot-level data from surveys of 3,700 farm households in six countries (Ethiopia, Tanzania, Uganda, Malawi, Zambia, and Zimbabwe) to measure DT maize adoption rates and their determinants. The data reveal considerable inter-country variation in farmer uptake of DT maize, from 9% of maize plots in Zimbabwe to 61% in Malawi. The major barriers to adoption include unavailability of improved seed, inadequate information, lack of resources, high seed price, and perceived attributes of different varieties. Based on the results, we recommend that seed companies and agro-dealers ensure adequate supply of DT maize seed in local markets and sell seed in affordable micro-packs (1 or 2 kg). Furthermore, the DTMA project and partners should ramp up promotional efforts to ensure widespread awareness and understanding of the benefits of the new DT maize varieties.This is the publisher’s final pdf.

Drought tolerant maize for farmer adaptation to drought in sub-Saharan Africa: Determinants of adoption in eastern and southern Africa
Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys
PURPOSE: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys. METHODS: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations. Founding principles are health ministry ownership, partnership and collaboration, and quality assurance and quality control at every step of the survey process. Support covers survey planning, survey design, training, electronic data collection and fieldwork, and data management, analysis and dissemination. Methods are adapted to meet local context and needs. Customisations, operational research and integration of other diseases into routine trachoma surveys have also been supported. RESULTS: Between 29th February 2016 and 24th April 2023, 3373 trachoma surveys across 50 countries have been supported, resulting in 10,818,502 people being examined for trachoma. CONCLUSION: This health ministry-led, standardised approach, with support from the start to the end of the survey process, has helped all trachoma elimination stakeholders to know where interventions are needed, where interventions can be stopped, and when elimination as a public health problem has been achieved. Flexibility to meet specific country contexts, adaptation to changes in global guidance and adjustments in response to user feedback have facilitated innovation in evidence-based methodologies, and supported health ministries to strive for global disease control targets
