Abstract |
The cause of cyclic strabismus is not clear but is assumed to be an abnormality of the biological clock mechanism. Secondary factors, combined with surgery or trauma as well as unknown causes stimulate its occurrence and may be followed by the periodicity of strabismus. We report postoperative follow-up results of 4 cases of cyclic esotropia following surgery. Two cases (case 1 and 2), who developed cyclic esotropia after surgery for intermittent exotropia, show good postoperative alignment without periodicity. But in case 3, originally treated for intermittent exotropia after receiving treatment for consecutive esotropia, the patient reverted to original condition. In case 4, originally treated for congenital glaucoma and receiving secondary treatment for cyclic esotropia, the cyclic esotropia was recurred. After surgery for consecutive cyclic strabismus, it is necessary to follow up for a long time. |
