Description
A 22-year-old man complained of double vision after receiving a craniotomy procedure due to hemorrhage caused by cerebral arteriovenous malformation in the right parieto-occipital area. The patient was referred to us from the hospital for strabismus surgery 2 years after the onset of double vision. He manifested right exotropia with convergence insufficiency. Visual field testing showed a left inferior quadrantanopia. Version eye movement was unrestricted in all directions. Furthermore, accommodative function showed a reduction in the amplitude of accommodation of the right eye, and convergence reaction in the right eye was slightly decreased. However, using an electronic pupillometer, the pupillary light reaction was normal with no difference between the right and the left eye. After undergoing an 8-mm right external rectus muscle recession, convergence became possible and an orthophoric eye position was maintained. The right parieto-occipital area plays an important role in eliciting near reflexes which led us to hypothesize that this area might be responsible for exotropia with convergence insufficiency.
