Factors associated with ocular injuries among adult road traffic accident patients presenting at Mulago National Referral Hospital, Uganda.

Background: Ocular trauma is the leading cause of unilateral blindness globally. Road traffic accidents are among the top risk factors for ocular trauma. Objectives: This study aimed to evaluate factors associated with ocular injuries among adult road traffic accident patients at Mulago Hospital, Uganda. Methods: A cross-sectional study was conducted among adult road traffic accident patients. History taking and ophthalmological examination were performed on consenting participants. Data was analysed using STATA version 14.0. Results: Overall, 428 road traffic accident cases were enrolled, of which majority (84.3%) were male. Age 30-39years (aOR = 0.58, 0.36 - 0.94, p = 0.027), being male (aOR = 2.64, 1.21 - 5.13, p = 0.004) and being a passenger of motor vehicle/cycle (aOR = 3.85, 1.49 - 9.93, p = 0.005) were the factors associated with ocular injuries among the participants. Conclusions: Age 30-39 years, male gender and being a passenger of motor vehicle/cycle were the factors associated with ocular injuries among the adult road traffic accident patients. Ocular injuries were more common among the road users who did not use safety measures. Use of safety measure by passengers of motor vehicles and cycles is recommended.

Prevalence and risk factors for visual impairment among elderly patients attending the eye clinic at Mulago National Referral Hospital, Uganda: a cross-sectional study.

Background: The elderly have an increased risk of developing visual impairment (VI). Due to the increase in life expectancy of individuals in Sub-Saharan Africa, the population of the elderly is projected to increase. It is thus postulated that the prevalence of VI will increase which is currently unknown in Uganda. Objective: To determine the prevalence and risk factors for VI among the elderly at Mulago National Referral Hospital eye clinic in Uganda. Methods: This was a cross-sectional study carried out in 2020 with consecutive enrolment of patients aged 60 years and above. Obtaining history was followed by systemic and ocular examination. Statistical analysis was performed to determine the prevalence and factors associated with VI. Results: Of 346 elderly participants examined, 174 (50.3%) were males and median age was 67 (IQR 63-74). Prevalence of VI was 32.1%. Cataract was the leading cause of blindness 54.1%, followed by refractive error (21.6%), glaucoma (11.7%), and corneal opacities (5.4%). Age (adjusted Prevalence Ratio (aPR): 1.05, 95% CI (1.02, 1.06)), history of diabetes mellitus (aPR 1.46, 95%CI (1.04, 2.05)), history of hypertension (aPR 1.46, 95%CI (1.10, 1.93)), having completed primary level of education (aPR 0.74, 95%CI (0.55, 0.98)) and secondary level of education (aPR 0.47, 95%CI (0.30,0.73)), presence of a cataract at examination (aPR: 2.28, 95%CI (1.66, 3.13)) were statistically significantly associated with VI. Conclusion: In Mulago hospital, the prevalence of VI among the elderly is high with majority of the causes being correctable. We recommend that efforts towards early case identification of causes of VI among the elderly should be a priority.

Prevalence and predictors of ocular complications among children undergoing nephrotic syndrome treatment in a resource-limited setting.

BACKGROUND: Nephrotic syndrome is the most common glomerulopathy among children aged 2-18 years and high dose corticosteroids are the backbone of its management. Potentially blinding ocular complications often result from nephrotic syndrome and/or its treatment. We conducted a study to determine the prevalence and predictors of ocular complications among children undergoing nephrotic syndrome treatment at Mulago National Referral Hospital. METHODS: This was a cross-sectional study conducted for three [3] months at the pediatric renal unit of Mulago National Referral Hospital (MNRH). Data from a consecutive sample of 100 children was collected using a semi-structured questionnaire, entered into Epi-data 4.4.2 and exported to STATA 14 for analysis at univariate, bivariate and multivariate levels. A robust Poisson regression model was used to identify predictors of ocular complications. RESULTS: Out of 100 patients examined, 80(80%) had ocular complications. The median age was 10 (IQR: 7-12) and 52 (52%) were girls. The most frequent complications were hypertrichosis and refractive errors in 71% (95%CI 61.1-79.6) and 56% (95%CI 45.7-65.9) of the patients respectively. Age above 10 years was the predictor for ocular complications with a RR = 1.37 (95%CI:1.14-1.64) p = 0.001. CONCLUSIONS: We found a high prevalence of ocular complications among children with nephrotic syndrome in this tertiary hospital. The predictor of ocular complications was age greater than 10 years. We recommend that all children with nephrotic syndrome undergo a baseline ocular examination prior to commencement of treatment and be reviewed periodically by an ophthalmologist.

Factors associated with delayed uptake of cataract surgery among adult patients at Mulago National Referral Hospital, Uganda.

BACKGROUND: Cataract is the leading cause of blindness globally. Many patients with cataract in developing countries delay to come for cataract surgery. OBJECTIVES: This study aimed to determine the factors associated with delayed uptake of cataract surgery among adult patients seen at Mulago National Referral Hospital eye clinic in Uganda. METHODS: Employing a hospital based cross-sectional study, adult patients with cataract and having moderate visual impairment or blindness were recruited. Patient-related factors for delayed surgery were assessed using a predetermined questionnaire. Data was analyzed using stata version 14.2. Logistic regressions were used to determine the factors associated with delayed uptake of cataract surgery among these patients. RESULTS: Eighty two participants with operable cataract were evaluated. Females were 44 (54%) and the mean age of participants was 67 years. Fifty three (65%) had delayed uptake of cataract surgery. The factors associated with delayed uptake of cataract surgery among patients with cataract were financial constraint, felt no need for surgery and good unilateral vision. CONCLUSIONS: Financial constraints, no felt need for cataract surgery and having good unilateral vision are the factors associated with delayed uptake of cataract surgery among cataract patients. We recommend cataract surgical outreach to remote areas and health education.
