I read with interest the report by Stroman et al1 describing magnetic resonance imaging in patients with low-tension glaucoma published in the February issue of the Archives. The finding of diffuse cerebral small-vessel ischemic changes in patients with low-tension glaucoma adds to the evidence that suggests that ischemia may play a role in this disorder. It would be interesting to know, however, if any of the patients in this study had migraine headaches. Phelps and Corbett2 reported a higher incidence of headache in elderly patients with low-tension glaucoma than in normal elderly controls and believed that there was an association between migraine and low-tension glaucoma. In addition, focal deep white matter abnormalities on magnetic resonance imaging studies have been described in patients with migraine, and may be related to small-vessel ischemia due to vasospasm.3 The relative role of migraine-related ischemia in the pathogenesis of these magnetic resonance
