    Relationship Between White Matter Hyperintensities and Retinal Nerve Fiber Layer, Choroid, and Ganglion Cell Layer Thickness in Migraine Patients

    Aim To compare the relationship between white matter hyperintensities (WMH) on brain magnetic resonance imaging and retinal nerve fiber layer (RNFL), choroid, and ganglion cell layer (GCL) thicknesses in migraine patients and healthy subjects. We also assessed the role of cerebral hypoperfusion in the formation of these WMH lesions. Methods We enrolled 35 migraine patients without WMH, 37 migraine patients with WMH, and 37 healthy control subjects examined in the Neurology outpatient clinic of our tertiary center from May to December 2015. RFNL, choroid, and GCL thicknesses were measured by optic coherence tomography. Results There were no differences in the RFNL, choroid, or GCL thicknesses between migraine patients with and without WMH (p>0.05). Choroid layer thicknesses were significantly lower in migraine patients compared to control subjects (p<0.05), while there were no differences in RFNL and GCL thicknesses (p>0.05). Conclusions The only cerebral hypoperfusion' theory was insufficient to explain the pathophysiology of WMH lesions in migraine patients. In addition, the thinning of the choroid thicknesses in migraine patients suggests a potential causative role for cerebral hypoperfusion and decreased perfusion pressure of the choroid layer.

    Atypical Intrapapillary Hemorrhage in a Patient with Glaucoma
    (2015) Gungor, Sirel Gur; Ozisik, Gulce Gokgoz; Akman, Ahmet; Asena, Leyla
    A 73-year-old man presented for routine follow-up. There were primary open-angle glaucoma, diabetes mellitus, and usage of acetylsalicylic acid in patient's history. Dilated fundus examination demonstrated cup hemorrhage in the right eye. Because of the progression of the superotemporal retinal nerve fiber layer defect in the last seven months, we think that the disk hemorrhage could be associated with glaucoma.
