Abstract

Purpose

To report a case of optic tract syndrome in which optical coherence tomography (OCT) demonstrated the specific findings of the retinal nerve fiber layer (RNFL).

Case summary

A 32-year-old male patient visited the hospital with right side visual field defect in both eyes that occurred immediately after a traffic accident 8 months prior. The visual acuity of both eyes was normal, and a relative afferent papil-lary defect was evident in the right eye. In addition, suspicious band atrophy of the right optic disc and thinning of the supe-rior and inferior arcuate bundle were observed in the left eye. On visual field examination, homonymous hemianopia was present. Optic tract syndrome was suspected, although there was no abnormality of the visual tract on MRI. On fast RNFL thickness 3.4 scan, a thinning of RNFL in the nasal and temporal segments in the right eye and superior and inferior seg-ments in the left eye were observed. Based on the findings, optic tract syndrome was diagnosed in the left eye.

Conclusions

We report specific OCT findings which can be useful when making a diagnosis of optic tract syndrome.
