PurposeThe purpose of this study was to compare and differentiate the clinical characteristics of intermittent exotropia (X(T)) in children and adults.MethodsThis study included 398 patients with X(T): 360 children ranging in age from 1 to 14 years and 38 adults over 15 years of age. Patients with neurological abnormalities or developmental delays were excluded. Clinical characteristics of interest included sex, age on first visit, age of onset, type of onset, duration to surgery, family history, chief complaints, type of fixation, refractive errors, sensory tests, angle of deviation, fundus examination, oblique muscle dysfunction, and other associated ocular disorders.ResultsIn both groups, an insidious onset was more common than a sudden onset (p=0.033). Outward deviation was the most common chief complaint in both groups, followed by photophobia in the childhood group, and diplopia in the adult group. The most common subtype of X(T) was the basic type. The mean near deviation was 23.6±7.9 prism diopters (PD) in the childhood group and 30.7±12.2 PD in the adult group (p=0.01). The mean distance deviation was 23.4±6.1 PD and 28.3±11.2 PD in the childhood and adult groups, respectively (p=0.028). The rate of fusion, measured with the Worth 4-dot test at near and distance was higher in the childhood group, as compared to the adult group (p=0.024 and p=0.048, respectively).ConclusionsAmong X(T) patients, the chief complaints, angle of deviation, and Worth 4-dot tests showed significant differences between the childhood and adult groups. Therefore, these are important factors to consider when assessing adults and children with X(T).
A 62-year-old-male presented at our clinic with decreased vision and metamorphopsia(OD) for several days. He had received an anti-fungal treatment two months before for the treatment of endogenous candida choroiditis (OU). Fluorescein angiography and optical coherence tomography revealed subfoveal, juxtafoveal choroidal neovascularization and tractionalposterior hyaloidmembrane (OD). Pars planavitrectomy and epiretinal membrane removal was done, and twointravitrealbevacizumabinjections were administered. His visual symptoms were not improved and chorioretinal scar and fibrotic change were detected at fovea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
