Epidemiological studies provide information on the prevention, treatment, and minimization of the impact of diseases on society. In the past two decades, a wide range of epidemiologic studies in ophthalmology have provided important information on the pattern of visual impairment and the major eye diseases that cause such vision loss [1]. Although several epidemiological studies of several age-related eye diseases (e.g., glaucoma, age-related macular degeneration, and cataract) have been conduct...

Amblyopia and strabismus are two common pediatric eye conditions with functional and cosmetic consequences. Amblyopia is associated with suboptimal vision, despite best spectacle correction in the absence of any other ocular and neural abnormality.1 Failure to diagnose and manage amblyopia before the age of 8 years can result in life-long visual impairment.1 Strabismus is the misalignment of the eyes, and if left untreated, may result in loss of binocularity and depth perception.1 Overall, globa...

Abstract Background Although the prevalence of strabismus is 2% to 5% in European-based and African-American populations, little is known about the prevalence of strabismus in Native-American populations. We report the prevalence of strabismus in children who are members of a Native-American tribe with a high prevalence of astigmatism. Methods Subjects were 594 children enrolled in Head Start and 315 children enrolled in kindergarten or first grade (K/1) in schools on the Tohono O'odham Reservat...

Background Strabismus is a common disorder of largely unknown cause reported to occur more frequently in children with neurodevelopmental conditions and in children born prematurely or of low birth weight. Population-based investigation of other potential early-life influences has been limited. Objective To investigate the prevalence of and the early-life risk factors associated with childhood strabismus. Design Cross-sectional analytical study of a nationally representative sample of children p...

Objective To determine the age-specific prevalence of strabismus in white and African American children aged 6 through 71 months and of amblyopia in white and African American children aged 30 through 71 months. Design Cross-sectional, population-based study. Participants White and African American children aged 6 through 71 months in Baltimore, MD, United States. Among 4132 children identified, 3990 eligible children (97%) were enrolled and 2546 children (62%) were examined. Methods Parents or ...

Objective: To estimate the distribution and predictors of some common visual problems (strabismus, amblyopia, hypermetropia) within a population-based cohort of children at the age of 7 years. Methods: Children participating in a birth cohort study were examined by orthoptists who carried out cover/uncover, alternate cover, visual acuity and non-cycloplegic refraction tests. Prospectively collected data on potential risk factors were available from the study. Results: Data were available for 782...

We previously revealed the prevalence of strabismus and amblyopia in elementary school children between 6 and 12 years of age in Japan in the year 2003. Questionnaires asking the number of children with different types of strabismus and amblyopia were sent to all elementary schools in Okayama Prefecture in the year 2005, and the results in the year 2005 were compared with those obtained in the year 2003. The number of children covered by the return of questionnaires was 84,619 (74%) of 113,763 t...

Purpose To describe the prevalence of strabismus and factors associated with its diagnosis in a representative sample of older Australian children. Design Cross-sectional, population-based study. Methods A representative stratified random cluster sample of 2353 children (aged 12 years) attending 21 secondary schools in Sydney, Australia was examined in 2004 to 2005 (response 75.3%). Cover testing was performed at near (30 cm) and distance (6 m); cycloplegic autorefraction, visual acuity, and ste...

PURPOSE To elucidate the differences in muscle bundle and satellite cells in medial rectus muscle through histological and Immunofluorescence studies of intermittent exotropia patients and normal controls. Materials and Methods: From January 2015 to December 2017, 15 patients who underwent medial rectus resection surgery at Kosin University Gospel Hospital were enrolled. Four medial recti muscles collected from two brain-dead men without strabismus were used as controls and compared with the int...
