Retinal photographs and thickness evaluation of the macular ganglion cell complex using optical coherence tomography. Retinal nerve fiber layer defects (white arrows, bottom left image) were observed in the right eye. Optical coherence tomography also showed thinning of the macular ganglion cell complex in the temporal superior aspect.

Additionally, the RS-3000 system of optical coherence tomography (Nideck Co.) was used to measure the thickness of the macular ganglion cell complex (Figure 1). Moreover, optical coherence tomography demonstrated thinning of the macular ganglion cell complex in the temporal superior aspect (Figure 1, left panel). The left eye of the patient exhibited no apparent glaucomatous alterations (Figure 1, right panel).
The results of a visual field examination using a Humphrey field analyzer. In the right eye, a visual field defect in the nasal inferior aspect corresponded to a defect in the retinal nerve fiber layer. In both eyes, a right-sided homonymous hemianopia-like visual field defect was observed.

HFA was conducted from the right to the left eye without interval. The mean deviations of the right and left eyes were -5.00 and -7.68 dB, respectively (Figure 2). A visual field defect in the nasal inferior aspect of the right eye corresponded to the retinal nerve fiber layer defect observed earlier. However, in both eyes, a right-sided homonymous hemianopia-like visual field defect was observed in both grayscale and pattern deviation images (Figure 2).
The results of visual field examinations using a Humphrey field analyzer (HFA) 1 and 10 months after initial HFA examination during a migraine attack. Follow-up findings revealed only glaucomatous visual field defects in the right eye without right-sided homonymous hemianopia-like visual field defects.

The HFA examination was repeated 1 and 10 months following the first examination (Figure 3), and mean deviations of -0.23 and -0.60 dB and -0.33 and 1.22 dB of the right and left eyes, respectively, were observed. The only abnormality was the visual field defect in the nasal inferior aspect of the right eye, corresponding to the retinal nerve fiber layer defect (Figure 3).
