Dynamic Stereopsis in Intermittent Exotropia Patients
Conditions
Brief summary
A novel dynamic random-dot stereopsis test that included motion + disparity (MD), motion (M), and disparity (D), in which the disparity cues range from 200 to 1200 arc-seconds was used. The characteristics of preoperative dynamic stereopsis in 83 intermittent exotropia patients and its associations with clinical features were analysed, and the prognosis was followed up on the 1st day and 2nd, 6th and 12nd months postoperatively.
