PURPOSE: To evaluate the ophthalmic features of Rathke\'s cleft cyst (RCC) and its association to radiological characteristics. METHODS: In this retrospective single center study, patients who showed typical findings suggestive of RCC on magnetic resonance imaging (MRI) and underwent relevant ophthalmic examination were recruited retrospectively. Patients were stratified into two groups according to the presence or absence of ophthalmic symptoms related to RCC. We reviewed patients\' demographic information, initial symptoms, endocrinological status, ophthalmic features, and characteristics on MRI. Height, size and location of RCC, as well as the optic chiasm displacement assessed from magnetic resonance images. RESULTS: Thirty-three patients (20 women and 13 men) were included in this study from among 335 patients with RCC on MRI. Fifteen patients had ophthalmic manifestation related to the cyst (Ophthalmic group), whereas 18 patients were not (Non-ophthalmic group). Headache was the most common initial symptom (15 patients, 45.5%), followed by visual disturbance (7, 21.2%), diplopia (1, 3.0%), retro-orbital pain (1, 3.0%), galactorrhea (1, 3.0%), and peripheral extremity discomfort (1, 3.0%). In 7 asymptomatic patients (21.2%), the lesion was an incidental finding during regular medical examination. Ophthalmic manifestation included visual field defect (14 patients, 93.3%) and diplopia (1 patient, 6.7%). The height, volume, and the coronal and sagittal displacements were larger in the ophthalmic group (P<0.001, all). Eleven patients who manifested ophthalmic symptoms underwent excision surgeries and 9 of them (81.8%) experienced visual function improvement. CONCLUSION: Appropriate ophthalmic examinations are warranted in patients with RCC, and treatment should be actively considered in patients with ophthalmic manifestations.
