Purpose: To analyze postoperative results of intermittent exotropia as a function of the difference in strabismic angles measured immediately and another time prior to the surgery.
Methods: We reviewed the clinical records of intermittent exotropia patients who received surgery and had differences greater than or equal to 10 prism diopters (PD) between the last preoperative measurement of strabismic angle and another previous measurement. After applying various exclusion criteria, 66 patients were entered into our study. At the last follow-up visit after surgery, we divided postoperative results into 3 categories: (1) poor; with greater than 10 PD of esotropia or angle of exodeviation of 20 PD or more (2) moderate; with 6-10 PD of esophoria/tropia or 10-19 PD exodeviation, or (3) good; with 1-5 PD of esophoria /tropia or an angle of exodeviation less than 10 PD, or orthophoria.
Results: Good results were higher in patients where the difference in strabismic angle was 10 PD or greater between the last measurement and any other earlier measurement.
Conclusions: In cases of Intermittent exotropia where the last preoperative value of strabismic angle was greater than any previous preoperative measurement, surgical dosage based on the last preoperative measurement yielded better results.

Detecting suppression is important for monitoring change in and determining surgical timing for intermittent exotropia. Here, we evaluate the results of a prospective, cross-sectional study of the "polarized glasses dissociation test" for detection of suppression. A positive result was defined as constant deviation of one eye at 6 m when viewing at distance with polarized glasses.

Purpose: To highlight findings of retinal exudation with exudative retinal detachment in a patient with Rubinstein-Taybi syndrome (RSTS) due to CREBBP mutation, successfully treated with laser, with the goal of adding to the known phenotypic spectrum of ophthalmic manifestations of RSTS.
Methods: A case report of a pediatric patient evaluated with multimodal imaging including fundus photography and fluorescein angiography.
Results: A 15-year-old female with RSTS caused by a frameshift mutation in CREBBP was referred for retinal examination under anesthesia.

Introduction: Stickler syndrome is a rare collagenopathy, caused by mutations in various genes coding for fibrillar collagens II, IX, and XI. The disorder can be subdivided into different groups, depending on the genes affected and clinical features found in patients. Ocular symptoms, such as high myopia, retinal detachments, or anomalies in the vitreous, are present in most forms of Stickler syndrome.

Purpose: To quantitatively compare the temporal parafoveal retinal thickness between intermittent exotropia (IXT) and healthy controls using optical coherence tomography (OCT), exploring the relationship between retinal structural changes and retinal correspondence.
Design: Cross-sectional study METHODS: Twenty basic type IXT with an exodeviation angle of 35 prism diopters (PD) were compared with 20 age-matched healthy controls. All enrolled participants underwent a comprehensive ophthalmic evaluation, including OCT, axial length, prism alternate cover test, retinal correspondence, and stereoacuity.

Background: The optimal myopia control measures for children with intermittent exotropia (IXT) have yet to be determined. This study evaluates the impact of Repeated low-level red-light therapy (RLRL) on myopia control in this population.
Methods: This retrospective study included 94 participants divided into three groups: Myopic children without strabismus receiving RLRL treatment (RLRL Group).
