Cyclic strabismus is an uncommon disorder in which strabismus alternates with orthotropia in alternating 24-hour periods, although cycles of other lengths have also been described. Alternate-day exotropia is a rare form of cyclic strabismus which, to date, has been reported in few patients. We describe a case of alternate-day exotropia in a child who had previously undergone surgical correction of constant esotropia.

Purpose: To evaluate children's reading performance with intermittent exotropia (IXT) and investigate possible associations among reading abnormalities, binocular visual function, and visual information processing.
Methods: This cross-sectional, case-control study involved 61 children with basic-type IXT and 40 healthy controls aged 7 to 13. Reading performance was assessed objectively using the Development Eye Movement (DEM) test and subjectively with the Dyslexia Checklist for Chinese Children (DCCC).

Purpose: The purpose of this study was to investigate the development of contrast sensitivity function (CSF) in children with intermittent exotropia (IXT) over 1 year and to explore the impact of surgical realignment on CSF.
Methods: A prospective study of 45 patients with IXT (aged 7-13 years) were matched with 30 healthy controls. Patients with IXT were categorized into the surgery group (n = 25) and the observation group (n = 20).

Background: Convergence insufficiency intermittent exotropia (CIX(T)) is a common type of strabismus in children, characterized by greater ocular deviation at near fixation compared to distance fixation. This study aimed to explore impact of slanted lateral rectus recession (S-LRc) compared to conventional lateral rectus recession (LR) on pediatric patients with CIX(T).
Methods: This retrospective study enrolled pediatric patients with CIX(T) at Shanxi Aier Eye Hospital between June 2022 and December 2024.

Oil droplet cataract is a rare pediatric lens opacity that can cause significant amblyopia if not promptly diagnosed and treated. A 5-year-old male presented with intermittent exotropia and reduced vision in the left eye. Visual acuity was 6/6 in the right eye and 5/60 in the left eye, improving to 6/36 with correction.
