Correction of cyclovertical strabismus induced by limited macular translocation in a case of age-related macular degeneration.
OBJECTIVE
To report a case of strabismus surgery performed to treat cyclovertical strabismus induced by limited macular translocation.


METHODS
Case report.


RESULTS
A 62-year-old man suffering with age-related macular degeneration and subfoveal choroidal neovascularization, RE, underwent limited macular translocation surgery. The fovea was rotated downward, and his visual acuity improved from 20/100 to 20/25 postoperatively. Cyclovertical diplopia persisted for 6 months after the operation. A Hess screen test revealed a pattern that simulated an underaction of the superior oblique muscle and inferior rectus muscle with an overaction of the ipsilateral inferior oblique muscle. To treat the diplopia, advancement of the superior oblique muscle tendon and resection of the ipsilateral inferior rectus muscle were performed. Binocular single vision with 140 seconds of arc for stereopsis was obtained.


CONCLUSIONS
Cyclovertical strabismus after limited macular translocation is corrective with conventional surgery on the treated eye.
