RESUMO
AlM:To discuss the application of prism alternate cover test ( PACT) and perimeter strabismometry in strabismic operation.METHODS: A total of 145 patients with concomitant esotropia or exotropia, aging 2 ~ 50 years old, were included. They were examined by PACT and perimeter strabismometry before operation. The strabismic operations were performed, the orthotropia rate of postoperation was assessed.RESULTS:Using PACT and perimeter strabismometry, there was a significantly difference of deviating angle ( P0. 05) in moderate strabismic group. The functional cure rate of postoperation was respectively 70. 83%, 67. 01%; the clinical cure rate was 20. 84%, 24. 74%; invalid rate was 8. 33%, 8. 25% .CONCLUSlON: The application of PACT and perimeter strabismometry in strabismic operation design, referring to the eye axial length, this can be helpful of improving the cure rate postoperation and decreasing the danger of reopreation.
