Treatment of Cyclodiplopia with the Harada-Ito Operation

Anthony J. Locastro, M.D. Sang-Jin Kim, M.D. Albert W. Biglan, M.D.

Background: Cyclodiplopia is uncommon and occurs after a cyclovertical muscle palsy or as a sequela of a procedure or disease that disrupts the normal periocular anatomy.

Methods: We studied seven patients who had cyclodiplopia and were treated with a modification of the original Harada-Ito procedure.

Results: All seven patients had relief of their diplopia symptoms in primary gaze without complication; two had persistent cyclodiplopia outside of primary gaze. Five of the seven patients showed an increase in their binocular function as measured by increased fusion on the Worth four-dot test or by an increase in their stereoacuity or a combination of these.

Conclusions: The modification of the Harada-Ito procedure, used in this series appears to be an effective method of treatment for patients with cyclodiplopia.
