Symptoms And Signs

Background. Refractive errors are the most common cause of visual impairment worldwide. Its proportion varied among societies and is considered as a public health challenge. Symptoms and signs associated with refractive errors are the most worrisome and common presentations in the general practice in eye clinics. Aim. The goal of this study was to determine the types and presentations of refractive error among the 0–30-year-old Yemeni population to aid early identification, diagnosis, referral, and treatment. Methodology. A cross-sectional study including 1,500 out-patients aged from 0 to 30 years attending the ophthalmology clinic in Sanaa, Yemen (between 2012 and 2015). All patients underwent visual acuity examination, autorefractometer, and anterior and posterior segment examination and were grouped according to type, that is, myopia, hyperopia, and astigmatism. Results. Hyperopia was the most common single diagnosis (53.3%) followed by myopia (33.3%). Astigmatism was uncommon as a single diagnosis (13.4%) but commonly associated with hyperopia or myopia. Myopia was more common in males (42.9%) than in females (25%). Hyperopia was more in females (62.5%) than in males (42.9%). Age groups most affected by refractive errors were 13–18 years (27.7%), 19–24 years (24.8%), and 25–30 years (24.6%), respectively. Decreased vision (53%) was a common presentation in myopia and astigmatism (41.5%) and less in hyperopia (39.6%). Headache was common in astigmatism (56%), hyperopia (28.8%), and myopia (17.8%). Muscle imbalance, namely, exotropia (27.2%), is mainly found in myopia and esotropia (24.3%) in hyperopia. Conclusions. In addition to decreased vision, our patients with refractive errors mostly complain of headaches with clear variations with age and type of refractive error. Early identification and proper categorization of refractive errors by age, gender, and other demographics by general physicians in primary care can better deduce and make useful referrals to eye specialists.

The purpose of this study is to estimate the prevalence of refractive errors in children. Children of selected ages will be identified for visual acuity measurement, and primary eye examination will be performed. A cross-sectional study was conducted to evaluate the refractive errors in children in Saveetha medical college. A comprehensive eye examination was performed, and children with different types of refractive errors were found out. A total of 100 children were taken for the study. The sample size of the study is 100. Eye examination was performed, and refractive error was evaluated. The refractive errors that are most common in the affected age groups can be found out. The most common refractive error was found to be myopia, followed by hypermetropia and then astigmatism. This study helps to identify the most common type of error, and the causes can be found out. This is also helpful in the prevention of these errors. Early diagnosis will lead to proper and effective treatment. When these errors are left untreated, it can cause other severe effects in the eye. Awareness should be created among both the children and the parents about this problem, and the importance of regular eye examination can be stressed through this study.

Refractive error is a condition in which the cornea and lens fail to focus the light, resulting in reduced visual efficiency. Twelve million children are experiencing refractive errors worldwide and uncorrected refractive errors in children have been reported to cause asthenopia. This study aimed to determine the association between the types of refractive errors and asthenopia in children. This cross-sectional study was conducted on 111 students aged 10-13 years old in a public elementary school in Indonesia, SDN Penjaringan 10, in 2019. A questionnaire was used to assess asthenopia and the Snellen Chart, trial frames, and trial lenses were used for refractive errors examination. It was demonstrated that 87.4% of respondents experienced asthenopia, and 53.2% of respondents suffered from uncorrected refractive errors, mostly due to myopia. Fisher’s exact test results showed an association between refractive errors and asthenopia (p=0.019) with all myopic students experienced asthenopia. However, there was no significant association between astigmatism and asthenopia (p=0.754). In conclusion, not all types of refractive errors are associated with asthenopia.

Background: Refractive error is one of the most common causes of the visual impairment and second leading cause of treatable blindness. The objective of the study was to determine the mag­nitude of refractive errors in children. Methods: This was a hospital based cross-sectional study conducted on 254 children attending Ophthalmology OPD of Manipal Teaching Hospital, Pokhara. The children whose visual acuity was worse than 6/6 but improved with pinhole were included in this study. Vision test, retinoscopy and subjective refraction was done in all subjects and cycloplegic refraction was done when needed. Statistical analysis was carried out using Epi-info version 7. Results: The commonest type of refractive error was astigmatism (46.06%) followed by myopia (42.31%). Majority of children had low grade of refractive errors (46.85%). Among the children, “with the rule astigmatism” was maximum (27.56%). Majority of children were in the age between 11 to 15 years (77.95%). The refractive error was seen more in female (63.78%). Among the chil­dren of refractive errors, 29.13% had family history, 33.46% had given the history of wearing spec­tacles and 10.24% children had amblyopia. There was statistically significant association between refractive errors and age groups, history of wearing spectacles, amblyopia and grading of refractive errors. However, there was no statistically significant association of refractive error with gender, residence and family history. Conclusions: Astigmatism was the common type of refractive error followed by myopia. This study emphasizes the importance of detection of refractive error in children.

Background: Successful refractive error programmes arise from evidence that can be collected cost effectively and timely.Aim: To investigate the prevalence of uncorrected refractive error (URE), presbyopia and spectacle coverage in the Kamuli district, Uganda.Setting: The study was conducted in the Kamuli district in Uganda.Methods: The Rapid Assessment of Refractive Error (RARE) study design is a communitybased cross-sectional study using multistage cluster random sampling to gather information on refractive errors and presbyopia. Subjects aged 15 years and older were selected from the population in Kamuli district in Uganda. Vision impairment due to URE at distance and near and barriers to uptake of refractive error services were investigated.Results: Participants, N = 3281 (57.6% male), with an age range of 15–92 years were enumerated and the response rate was 100%. The prevalence of refractive errors was 4.6% (95% confidence interval [CI]: 3.7 – 5.5) and the spectacle coverage was 5.96% (95% CI 1.74% – 10.18%). The prevalence of uncorrected presbyopia was 50.3% (95% CI 47.6% – 53.0%) and the spectacle coverage was 0%. Thirty-three (or 1%) respondents were current spectacle users. One-hundred fourteen people (3.5%) had previously used spectacles; however, 50.9% of them discontinued spectacle use a year before the study because the spectacles were broken or scratched. The major barriers to spectacle uptake were accessibility of services and affordability of spectacles.Conclusion: The prevalence of URE and the barriers to uptake of refractive services will inform the implementation of refractive services in the study area. Key words: Uncorrected refractive errors; presbyopia and spectacle coverage

Abstract Background Describing contact patterns is crucial to understanding infectious disease transmission dynamics and guiding targeted transmission mitigation interventions. Data on contact patterns in Africa, especially South Africa, are limited. We measured and compared contact patterns in a rural and urban community, South Africa. We assessed participant and contact characteristics associated with differences in contact rates. Methods We conducted a cross-sectional study nested in a prospective household cohort study. We interviewed participants to collect information on persons in contact with for one day. We described self-reported contact rates as median number people contacted per day, assessed differences in contact rates based on participant characteristics using quantile regression, and used a Poisson model to assess differences in contact rates based on contact characteristics within age groups. We also calculated cumulative person hours in contact within age groups at different locations. Results We conducted 535 interviews (269 rural, 266 urban), with 17,252 contacts reported. The overall contact rate was 14 (interquartile range (IQR) 9–33) contacts per day. Those ≤18 years had higher contact rates at the rural site (coefficient 17, 95% confidence interval (95%CI) 10–23) compared to the urban site, for those aged 14–18 years (13, 95%CI 3–23) compared to < 7 years. No differences were observed for adults. There was a strong age-based mixing, with age groups interacting more with similar age groups, but also interaction of participants of all ages with adults. Children aged 14–18 years had the highest cumulative person hours in contact (116.3 rural and 76.4 urban). Conclusions Age played an important role in the number and duration of contact events, with children at the rural site having almost double the contact rate compared to the urban site. These contact rates can be utilized in mathematical models to assess transmission dynamics of infectious diseases in similar communities.
