[Treatment of dissociated vertical deviation by shifting fixating eye].

OBJECTIVE: To investigate the results of using shifting fixation eye to manage monocular or asymmetrical binocular dissociated vertical deviation (DVD). METHODS: Twenty-three DVD children whose corrected vision was better than 0.5 in the amblyopic eye were studied. The goal of the shifting fixation eye was gained by decreasing the vision of the primary fixation eye to 2 or 3 lines (Snellen Visual Acuity) lower than that of the fellow fixation eye by occlusion or optical methods. The vision, alignment and retinal correspondence were evaluated before and after the treatment. RESULTS: After the treatment, in 10 patients, the vision of the primary fixation eye did not decrease significantly and the vision of the fellow eye increased 2 lines. In 19 patients, a cosmetic result was achieved; the primary fixation eye was shifted in 4 patients that had similar hepertropia in two eyes (
