Non-arteritic anterior ischemic optic neuropathy and refraction.
A small cup-disk ratio has been reported as a risk factor in non-arteritic anterior ischemic optic neuropathy. Hyperopia is possibly related with a small cup-disk ratio. The purpose of the present study is to compare the refraction of 37 eyes with non-arteritic anterior ischemic optic neuropathy with a sex and age matched control group of 74 eyes. In our study, mild hyperopia was more frequently observed in the anterior ischemic optic neuropathy group than in the control group.
