View clinical trials related to Esotropia.
Filter by:To observe the early course of congenital esotropia, a form of childhood strabismus. This will determine the probability of spontaneous resolution. Researchers then will try to correlate this finding with various aspects of the esotropia such as the (1) size of the esotropia, (2) variability, and (3) presence of hyperopia. This information will be used to determine the feasibility of conducting a clinical trial to assess the benefit of early surgery for congenital esotropia and, if feasible, to refine eligibility criteria for the trial.
To determine whether the preoperative use of prisms in eyeglasses can improve the outcome of surgery for acquired esotropia, a type of strabismus. To determine whether patients who respond to prism adaptation by developing a new stable angle of -deviation have a better surgical result than do patients who do not respond to prism adaptation. To determine whether patients who respond to prism adaptation are more accurately corrected by operating for the prism-adapted angle or the original angle of deviation. To determine the usefulness of certain input variables (e.g., age at the time of surgery, size of the deviation, visual acuity, binocular function, refractive error) in predicting which patients are more likely to benefit from prism adaptation.
