A three step method of the determination of fixation status and retinal correspondence.
In examination and treatment of patients with strabismus one often encounters abnormal sensory adaptations such as eccentric fixation and anomalous retinal correspondence. Prognosis and treatment of strabismus are dependent on the presence or absence of these conditions. When eccentric fixation is present it becomes difficult to interpret the results of many tests used to determine retinal correspondence. This determination is further complicated when the patient is unable to give accurate responses. A technique utilizing visuoscopy and an afterimage has been performed on somewhat less cooperative patients. The results compare favorably to amblyoscopic measurements of the angle of anomaly.
