strabismus epidemiology

PURPOSE: To obtain epidemiological data on children with ocular morbidity attending a nodal district early intervention center (DEIC). METHODS: : After parental consent, we recruited children with ocular morbidity.

The objective of this review was to estimate the prevalence of strabismus and amblyopia in Africa. A systematic online literature search was conducted for articles on strabismus and amblyopia in Africa. Meta-analysis was performed, using the Freeman-Tukey double arcsine transformation, to estimate the prevalence of strabismus and amblyopia in Africa. Subgroup analyses were conducted according to age, gender, study year, and type of amblyopia. Meta-regression was used to evaluate the influence of predetermined factors on the prevalence of amblyopia...

BACKGROUND: Coats disease may cause diagnostic dilemma because of its variable clinical presentation that can be suspicious of retinoblastoma. Late sequelae of the disease are blinding with possible enucleation. We demonstrate the main histopathological findings of Coats enucleated eyes with literature review. METHODS: This was a retrospective study of all enucleated globes diagnosed as Coats disease over 30 years and were reviewed by two pathologists. The corresponding demographic data, clinical presentation, pre-operative clinical impression, and indication for enucleation were collected...

PURPOSE: To examine the epidemiological characteristics of children undergoing cataract surgery at a referral center in Sao Paulo State, Brazil, as well as the facts surrounding treatment delays. METHODS: In this transversal observational study, 240 operated eyes from 178 children undergoing cataract surgery were reviewed. The following aspects were analyzed: epidemiological and clinical characteristics, parental observations, red reflex test, operated eye, and age at cataract diagnosis and surgery...

PURPOSE: To evaluate the agreement between non-cycloplegic autorefraction (NCAR) and cycloplegic autorefraction (CAR) in an ethnically diverse population of preschool-aged children and the validity of the screening criteria used to refer for further evaluation. METHODS: This study included data from 7,073 preschoolers who underwent NCAR and CAR, which enabled refractive error classification based on the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) 2013 criteria...

PURPOSE: To determine the prevalence of ophthalmological findings suggesting an ocular cause for headache or occult neurological disease, among children with headache. METHODS: Retrospective cross-sectional study on children with headache at a tertiary outpatient ophthalmology clinic. All children underwent sensorimotor, anterior segment, and dilated fundoscopic examinations, with or without cycloplegic refraction. Prevalence of one or more new findings of ocular or occult neurological cause of headache, including glaucoma, uveitis, optic nerve elevation, or possible asthenopia from strabismus or refractive issues...

PURPOSE: Although eye abnormalities are reported in fetal alcohol spectrum disorders (FASD), no systematic review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines has been undertaken. Our aim was to document the range and prevalence of eye abnormalities reported in children with prenatal alcohol exposure (PAE) and/or FASD. METHODS: Searches of electronic databases and manual searches. Eligible articles were observational studies in children with PAE and/or FASD; peer reviewed journal articles in the English language; and studies reporting quantitative or frequency data on functional/structural eye abnormalities...

Nabais Sa-de Vries syndrome (NSDVS) is a neurodevelopmental disorder first described in 2020. The syndrome is caused by de novo missense mutations in speckle-type pox virus and zinc finger protein ( SPOP ) on chromosome 17q21. The syndrome is divided into two forms (NSDVS Type 1 and NSDVS Type 2) based on the consequence of the mutation involved. In this report, we present the clinical features in a young male patient with suspected NSDVS1 and summarize the features of the reported affected individuals thus far, with a focus on the ophthalmic manifestations...

Aim of the study was to assess: (a) the prevalence and type of strabismus, ptosis and eyelid dynamic disorders features, (b) the prevalence of refractive errors, amblyopia and, (c) their association with ocular/systemic syndromes in a cohort of patients. This is a retrospective observational multicenter cohort study. Patients with coexisting ocular motility disorders, comitant and incomitant strabismus, ptosis and dynamic eyelid disorders who have never undergone surgery were enrolled throughout a 3-years a study period...

The popularity of toy guns among children is a growing public health concern due to reports of ocular injury. Most ocular injuries caused by toy guns occur in children younger than 10 years and at home. Dissemination of this information to parents and pediatricians is important to formulate safety measures.

PURPOSE: To characterize the epidemiology of eyelid lacerations, identify risk factors for canalicular involvement, and describe postoperative complications following laceration repair. METHODS: All patients undergoing eyelid laceration repair at a tertiary care, level I trauma center children's hospital from November 2010 to April 2021 were identified by a Current Procedural Terminology code search. Patient characteristics, surgical characteristics, and surgical outcomes were collected via chart review...

Infantile cataracts remain one of the most treatable causes of lifelong visual impairment. While the chance of improving vision for children with infantile cataracts has never been better, significant global and socioeconomic disparities still exist in their early management. Recent epidemiological studies reveal a stable prevalence of infantile cataracts in high-income countries and highlight challenges in determining the prevalence of infantile cataracts in low-income countries. Detailed descriptions of cataract morphology may inform us as to etiology, provide guidance with regards to surgical approach, and have prognostic value...

The aim of this study is to investigate the epidemiology of ophthalmic complications of retinopathy of prematurity (ROP) after preterm birth using population-based database in South Korea. Using the National Health Insurance database, ophthalmic complications among premature infants born in 2007-2008 during their 10-year follow-up period were identified. Annual cumulative incidence rate and period prevalence of complications at each age were analyzed among those with ROP and those who underwent treatment for ROP (tROP)...

AIM: The current study was designed to provide detailed information on the prevalence of ocular abnormalities in patients with cerebral palsy (CP). METHODS: Four international online scientific databases, including Web of Science, PubMed, Scopus, and Google Scholar were systemically searched. First, the titles of the articles were evaluated, and if relevant, their abstracts and full texts were reviewed. The quality of the studies was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist...

METHODS: : Retrospective study of de-identified claims data from the OptumLab® Data Warehouse (OLDW) between 2007 and 2018. All children (<19 years) in the OLDW with coverage were studied and those with a claim for a significant eye disease (strabismus, amblyopia, nystagmus or structural eye disorders) with minimum 6-months follow-up were studied...

BACKGROUND: Parents can be psychologically impacted when their children are diagnosed with eye diseases, such as blindness, strabismus, and eye cancer. Stress can reduce the quality of parental care and may be linked to the deterioration of parents' and children's mental and physical health and family dynamics. No systematic literature review on parental stress in ophthalmology has been found to provide evidence synthesis capable of stimulating and defining new studies and thereby promoting research in this field...
