The role ocular alignment stability was also evaluated postoperatively. Methods In this prospective study, 30 adolescents IXT successfully corrected 1 month were followed for 12 months, children vision enrolled as controls. Stereopsis, fusional vergence amplitude, sensory fusion, accommodative...

Intermittent exotropia (IXT) is the most common type of in China. Surgery usually required to align eye deviation maintain or obtain better binocular visual function. However, there a high rate exodrift recurrence surgically treated patients. Orthoptic therapy sometimes recommended for IXT patients after surgery. lack high-quality randomized controlled trials prove that orthoptic could be an effective supplement surgical treatment The main purpose this study test clinical effectiveness...

Abstract Reading speed in intermittent exotropia (IXT) children has been minimally examined. This study assessed reading school-age with IXT and determined clinical characteristics of that impacted their ability. We compared the 63 (10–14 years) to 44 age-matched normal counterparts. In addition, correlation between were evaluated. The was 231 ± 51 CPM, while counterparts 257 33 CPM. Age, gender found be factors associated IXT. After adjusting for age gender, we a significant LogTNO group...

Purpose: To determine binocular summation of surgically treated intermittent exotropia (IXT) patients by measuring the contrast threshold. Methods: We recruited 38 IXT aged 8-24 years and 20 age-matched healthy controls. All participants had normal or corrected-to-normal visual acuity (Snellen ≥ 20/20) in both eyes. The undergone surgery at least a year prior to study. Twenty-one them obtained good alignment 17 experienced recurrence exotropia. measured observers' monocular sensitivities...
