Purpose: To report the results of ganglion cell analysis in a patient with optic tract syndrome who was previously diagnosed with glaucoma.
Case summary: A 32-year-old male, who had been diagnosed with glaucoma 12 years ago, but had not visited an ophthalmology clinic since then, came to our clinic for evaluation of his glaucoma. Both eyes showed an increased cup-to-disc ratio and temporal pallor of the disc. Retinal nerve fiber layer (RNFL) optical coherence tomography showed thinning of the superior, inferior, and temporal peripapillary RNFL in both eyes. On ganglion cell analysis (GCA), ganglion cell layer thinning in the nasal region of the right eye and in the temporal region of the left eye was observed. The visual field test showed right incongruous homonymous hemianopsia. After the atrophic change of the left optic tract was confirmed by orbit magnetic resonance imaging, he was diagnosed with left optic tract syndrome.
Conclusions: We report the results of GCA in a case of optic tract syndrome, previously diagnosed as glaucoma. GCA can be useful when diagnosing optic tract syndrome.
