“…However, the prevalence of astigmatism has a great variation in different studies, ranging from 0.3% in Thailand 83 to 91.9% in Benin. 44 The use of a cylinder power >0.5 D as the cut point in our study limited this range. Although part of the variation can be due to differences in age groups, we observed this variation in both adults and children.…”

PurposeThe aim of the study was a systematic review of refractive errors across the world according to the WHO regions.MethodsTo extract articles on the prevalence of refractive errors for this meta-analysis, international databases were searched from 1990 to 2016. The results of the retrieved studies were merged using a random effect model and reported as estimated pool prevalence (EPP) with 95% confidence interval (CI).ResultsIn children, the EPP of myopia, hyperopia, and astigmatism was 11.7% (95% CI: 10.5–13.0), 4.6% (95% CI: 3.9–5.2), and 14.9% (95% CI: 12.7–17.1), respectively. The EPP of myopia ranged from 4.9% (95% CI: 1.6–8.1) in South–East Asia to 18.2% (95% CI: 10.9–25.5) in the Western Pacific region, the EPP of hyperopia ranged from 2.2% (95% CI: 1.2–3.3) in South-East Asia to 14.3% (95% CI: 13.4–15.2) in the Americas, and the EPP of astigmatism ranged from 9.8% in South-East Asia to 27.2% in the Americas. In adults, the EPP of myopia, hyperopia, and astigmatism was 26.5% (95% CI: 23.4–29.6), 30.9% (95% CI: 26.2–35.6), and 40.4% (95% CI: 34.3–46.6), respectively. The EPP of myopia ranged from 16.2% (95% CI: 15.6–16.8) in the Americas to 32.9% (95% CI: 25.1–40.7) in South-East Asia, the EPP of hyperopia ranged from 23.1% (95% CI: 6.1%–40.2%) in Europe to 38.6% (95% CI: 22.4–54.8) in Africa and 37.2% (95% CI: 25.3–49) in the Americas, and the EPP of astigmatism ranged from 11.4% (95% CI: 2.1–20.7) in Africa to 45.6% (95% CI: 44.1–47.1) in the Americas and 44.8% (95% CI: 36.6–53.1) in South-East Asia. The results of meta-regression showed that the prevalence of myopia increased from 1993 (10.4%) to 2016 (34.2%) (P = 0.097).ConclusionThis report showed that astigmatism was the most common refractive errors in children and adults followed by hyperopia and myopia. The highest prevalence of myopia and astigmatism was seen in South-East Asian adults. The highest prevalence of hyperopia in children and adults was seen in the Americas.

The cases of hypermetropia in patients aged 5 to 40 years were studied at Aristide Le Dantec hospital in Dakar. There are 85 patients including 28 men and 57 women. The average age was 22 years old. Headache was the most common reason for consultation (79.69%). The average consultation time was 6 days after onset of functional symptoms. Complications were strabismus (21.88%) and amblyopia (3.12%). A negative impact on the socio-professional level was noted in 60.94%. The treatment consisted of an optical correction by glasses in 96.87%.

“…In Africa, several studies on static ametropia have been devoted to the school environment, particularly in its aspects on the frequency, prevalence and negative impact on school performance according to Ayed et al (2002), Sounouvou et al (2008), andNonon et al (2013). However, few studies have addressed static ametropia in academia.…”

Purpose: We aimed to evaluate negative impact on academic performance of University students in Kinshasa associated to statics ametropia in our setting. Methods: A cross-sectional study was performed in the Department Ophthalmology of University Hospital of Kinshasa from January to June 2022. The Faculties, department and audience were taken to carry out a survey of three-stage probability sampling technique while the students were enrolled on the register's presence to space four names (k = 4). The students have been taken ophthalmologic exam systematically visual acuity (Monoyer Ladder), slit lamp, fund ophthalmoscopy and automatic refractometer KR-920Top Con to determine ametropia. Academic performance was classified in this ways: poor (40% -49%), passable (50% -59%), fairly (60% -69%), good (70% -79%), very good (80% -89%) and excellent (90% -99%). Sociodemographic and clinical data have been systematically recorded in this study. Data was enrigestred in Excel software. We used SPSS version 20.0 for statistical analysis and Chi-square was used to compare proportion. Univariate and multivariate analyses were used to test association between statics ametropia and environmental factors. p-value inferior to 0.05 or equal was considered significant.Results: A total of 600 students were examined. Their age ranged from 18 to 56 years and mean age ± SD was 24.6 ± 7.1 years. Sex ratio was 1.2. The main complaints were difficulty to watch the black board 30.3%, photophobia 14.6%, blurred vision 14%, tired vision 12.1%, headache 7.8%, ocular eyes, tearing eyes 4.3%, low visual acuity 4.1%, ocular prickling 2.6%, vertigo 2.3%, itchy eyes 2.1% and red eyes 1.3%. Myopia represented 36.6%, Hypermetropia 19.8%, Simple Astigmatism myopia 8.8%, Compose Astigmatism myopia 6.5%, Mix astigmatism 3.1% and spherical anisometropia 1.8%. Video playing,
