    Aim: To determine the epidemiology of ocular allergy(OA) in secondary school children in Trinidad and Tobago Method: A descriptive cross-sectional school-based study was done using the ISAAC questionnaire to assess the epidemiology of OA. A spinner wheel website was used to select schools to be included. Information on demography, presence of ocular allergy symptoms, associated risk factors, and impact of ocular allergy were obtained. The data collected was exported to Statistical Package for Social Sciences (SPSS) and the correlation between variables was examined with the use of Pearson Chi-square test using a p-value of <0.05 as the threshold for statistical significance. Results- A total of 420 students comprising of 198 males (47.1%) and 222 females (52.9%) aged 11–18 years participate in the study. The prevalence of OA was 49.3% (207 children) and SAC was the most prevalent (90.3%) type of OA found. The prevalence of OA was higher among 14 years age group (23.4%) and females (58.8%). Difficulty breathing, wheezing, asthma, food, rhinitis, atopic eczema, and mites were associated with OA. Conclusion- The prevalence of OA among secondary school students in Trinidad was relatively high (49.3%) as compared to various studies conducted across the globe.

    The Prevalence of Binocular Vision Anomalies and Refractive Error among Secondary School Children in Southern Trinidad and Tobago.
    (Faculty of Medical Sciences, The UWI, St. Augustine Campus, Trinidad and Tobago, 2023) Dr Ngozika Ezinne; Mohansingh, Safiyya; Rattan, Vishal
    This research seeks to investigate the prevalence of Binocular Vision Anomalies and Refractive Error among Secondary School Students in Trinidad and Tobago. Methods: A cross sectional school-based study was done by conducting vision screenings in two different schools in south Trinidad to investigate the prevalence of BVA and refractive error. A website called picker wheel was used to select schools to be included. Information on demography was obtained, and refractive error and binocular vision testing were conducted. The data collected was entered into Microsoft excel and exported to Statistical Package for Social Sciences (SPSS). Pearson Chi Squared was used to describe the distribution of categorical values and association between variables were evaluated using Spearman’s rho using a p-value of <0.05 as the threshold for statistical significance. Results: A total of 95 students comprising of 49 (51.6%) males and 46 females (48.4%) ages 12-18 years participated in this study. The prevalence of BVA was 13.7% (13 children) with convergence insufficiency (6.2%) being the most prevalent type found. Refractive error was more prevalent accounting for 64.7% of participants, with myopia being the most prevalent (54.2%) type of refractive error. It was determined using the Spearman rho test that there is no statistically significant correlation between BVA and refractive error. Conclusion: The prevalence of BVA and refractive error among secondary school students in south Trinidad was found to be 13.7% and 64.7% respectively.
