Abstract:AIM: To seek an effective method to cure the large angleexotropia by unilateral surgery.
METHODS: A case-control study was used to compare two operation treatments of large angleexotropia. Totally 39 patients of large angle exotropia complied with highly amblyopic were divided into group A and group B according to the surgeon methods. Monocular normal quantity of lateral rectus recession combined the edge cutting in the external rectus and medial rectus shortening were performed in group A. The same operations except the edge cutting in the lateral rectus were performed in group B. A: B was equal to 1:2, with age and visual acuity matched. The eye position ≤±8△ 6 months postoperative was seen as the criteria of cure. The cure rate of two groups were compared with χ2- Fisher's exact probability test.
RESULTS: The cure rate was 84.6% in group A and 46.2% in group B. There was significant difference in the cure rate between the two groups(P<0.05).
CONCLUSION: The operation that the monocular normal quantity of lateralrectus back combined the edge cutting in the external rectus is safe and effective than the traditional method.
