Arm Description
At initial visit(of study), the physician will reduce the diopter of hyperopic glasses as much as the patient can maintain their eye alignment (maximum amount 1.5D).
Outcomes
Primary Outcome Measures
eye alignment
Follow-up examinations are scheduled at 1 week, 1 month, 3 months, and 6 months after the patients begin wearing under-corrected spectacles. At every visit, symptoms such as asthenopia, diplopia, or blurred vision will be documented and ocular examinations including ocular alignment status for distance and near will be performed.
Secondary Outcome Measures
stereopsis
Follow-up examinations are scheduled at 1 week, 1 month, 3 months, and 6 months after the patients begin wearing under-corrected spectacles. At every visit, tests of fusion and stereoacuity will be performed.

5. Study Description
Brief Summary
In most clinics, physicians reduce diopter of hyperopic glasses in older patients with accommodative esotropia. However, there are risks of decompensation in that practice. The authors are going to try measure the change of stability of eye alignment after reducing diopter of hyperopic glasses.
Detailed Description
Inclusion criteria :
patients with accommodative esotropia
At initial visit(of study), the physician will reduce the diopter of hyperopic glasses as much as the patient can maintain their eye alignment (maximum amount 1.5D).
Outcome measure :
Follow-up examinations are scheduled at 1 week, 1 month, 3 months, and 6 months after the patients begin wearing under-corrected spectacles. At every visit, symptoms such as asthenopia, diplopia, or blurred vision will be documented and ocular examinations, including visual acuity and ocular alignment status for distance and near will be performed. Tests of fusion and stereoacuity will be performed at the 1-month, 3-month, and 6-month follow-up visits.
