University students are prone to developing refractive errors due to their curriculum that requires a lot of near work affecting their performance and quality of life unknowingly. Genetic and environmental factors are thought to play a role in the development of refractive errors. This study addresses the paucity of knowledge about refractive errors among university students in East Africa, providing a foundation for further research. Objectives: To determine the prevalence and factors associated with refractive errors among students in the Faculty of Medicine at Mbarara University of Science and Technology. Methodology: This was a cross-sectional descriptive and analytical study in which 368 undergraduate students selected using random sampling were assessed for refractive errors from March 2021-July 2021. Eligible participants were recruited and their VA assessment done after answering a questionnaire. Students whose VA improved on pin hole had subjective retinoscopy and results were compiled and imported to STATA 14 for analysis. Results: The prevalence of refractive errors was 26.36% with (95% CI) among university students especially myopia. Myopia is most predominant at 60%, followed by 37% Astigmatism and hyperopia of 3% among medical students. Astigmatism consisted of largely myopic astigmatism 72% (26) and 28% (10) compound/mixed astigmatism only. Student positive family history of refractive error was found to have a statistically significant relationship with refractive errors with AOR 1.68 (1.04 - 2.72) (95% CI) and P (0.032). Conclusion: The prevalence of refractive errors among university students, especially myopia, was found to be high and family history was associated with students having refractive errors.展开更多

Hypertensive patients are at a risk of developing and progression of Open Angle Glaucoma (OAG) which is a major cause of blindness in the world. The aim of this study was to determine the prevalence of raised IOP and associated factors among hypertensive patients attending the hypertension clinic at Mulago National Referral Hospital in Uganda. <strong>Materials and Methods:</strong> A cross-sectional study was conducted from December 2018 to March 2019. Our sample comprised hypertensive patients recruited after obtaining consent. Participants were sampled consecutively and underwent both a general medical and ocular examination. A questionnaire was used to collect data on socio-demographic characteristics, ocular and medical factors. Data were entered into the computer using the statistical data package of Epidata version 3.1 and exported to STATA version 14 for analysis. <strong>Results:</strong> Of the 405 hypertensive study participants, mean age was 57.1 years (range 25 to 90 years, SD = 12.4 years). The overall prevalence of raised intraocular pressure was 11.6% (95% CI 8.8 - 15.1). The mean IOP among all participants was 15.2 mmHg (SD = 4.3) with a range of 3 - 34 mmHg. The factors with a statistically significant association with raised intraocular pressure after multivariate analysis were a positive family history of Glaucoma (OR 57, CI 10.33 - 315.34, P < 0.001) and Eye trauma (OR 7.84, CI 1.02 - 60.02 P = 0.047). <strong>Conclusions:</strong> The prevalence of raised intraocular pressure among hypertensive patients attending the hypertension clinic in Mulago National Referral hospital, Uganda was found to be high.展开更多
