AIM:To analyze the operation time selection and effect observation of the surgery for children with partially accommodative esotropia to provide the reference for treatments.

METHODS:Fifty-two children with partially accommodative esotropia received surgeries in our hospital were selected, and they were divided into group A(10 cases), group B(25 cases)and group C(17 cases)according to operation time. The patients in group A were taken surgical treatment when the disease was diagnosed within 1a, those in group B were taken treatments within 1～3a, while those in group C were treated over 3a. The operation efficacy was compared.

RESULTS:There were 88% >6 years children developed stereo vision after surgeries, which was significantly higher than those < 3 years(30%, P<0.05).The chance for the patients to develop stereo vision was obviousely correlated with the operation time. The rates of patients who develop stereo vision after operations were 80% in group A and 76% in group B, both of which were significantly higher than that(41%)in group C(P<0.05). The efficacy rates of group A and group B were 90%, 88% respectively, both of which were significantly higher than that(71%)of group C(P<0.05).

CONCLUSION:Children with partially accommodative esotropia should receive surgical treatment as early as possible once they are 6 years old. The surgical amount should be decided by the esotropia deviation and the uncorrected visual acuity.
