Objective: To assess the strabismus prevalence and associated factors among children aged ≤15 years.
Methods: This hospital-based cross-sectional study was conducted from March 2017 to October 2017 in the Department of Ophthalmology & Optometry, Hawassa University Comprehensive Specialized Hospital. Interviewer-administered questionnaires were used to collect relevant data and clinical examinations were performed for patient diagnosis.
Results: Overall, 582 children participated in the study (response rate, 97%). The prevalence of childhood strabismus was 17.9% [95% confidence interval: 14.6-21.1]. Additionally, 9.6%, 16.7%, and 9.6% of the children had anisometropia, amblyopia, and dense cataract, respectively. Among the 16.7% of children with amblyopia, 56.7% had strabismus; among the 22.5% of children with clinically significant refractive error, 52.7% had strabismus. Moreover, among the 9.6% of children with anisometropia, 58.9% had strabismus. The presence of amblyopia (adjusted odds ratio [95% confidence interval]: 3.9, 1.7-8.6), age <5 years (13.5 [5.0-36.1]), age 5 to 10 years (6.1 [2.3-16.3]), and clinically significant refractive error (13.3 [5.8-30.6]) were significantly associated with childhood strabismus.
Conclusions: The prevalence of strabismus was relatively high among patients in this study. Early screening for childhood strabismus is essential. A well-controlled community-based study is needed to confirm strabismus prevalence and predictors.

Background: Congenital cytomegalovirus (CMV) infections are associated with eye manifestations, especially in patients with systemic disease. However, there are no ophthalmic screening guidelines for infants with congenital CMV.
Methods: Retrospective review of pediatric patients (< 18 years old, 2010-2023) with a diagnosis of congenital CMV and at least 1 eye examination.

We employed high-resolution fMRI to distinguish the impacts of anisometropia and strabismus amblyopia on the evoked ocular dominance (OD) response. Sixteen amblyopic participants (8 females) plus 8 individuals with normal vision (1 female), participated in this study for whom, we measured the difference between the response to stimulation of the two eyes, across areas V1-V4.In controls, the evoked OD response formed the expected striped pattern within V1.

Acute acquired comitant esotropia (AACE) is a concomitant strabismus characterized by sudden onset, mostly associated with diplopia. The prevalence of AACE has significantly increased, and various management approaches have been recommended in recent years. This study by the Council of Asia-Pacific Strabismus and Pediatric Ophthalmology Society aimed to provide an overview of the clinical features, etiology and the nonsurgical and surgical treatment recommendations for the condition to equip strabismus specialists with the most updated knowledge.

Ophthalmology, Royal Hospital for Children, Glasgow, UK.
Background: Very premature infants screened for retinopathy of prematurity (ROP) that do not develop ROP still experience serious visual developmental challenges, and while it is recommended that all children in the UK are offered preschool visual screening, we aimed to explore whether this vulnerable group requires dedicated follow-up.
Methods: We performed a real-world retrospective observational cohort study of children previously screened for ROP in NHS Greater Glasgow and Clyde (Scotland) between 2013 and 2015. We excluded those with any severity of ROP identified during screening.
