Abstract Purpose:To report findings by optical coherence tomography(OCT)in non-functioning pituitary adenoma. Particular attention was made to the relationship between subjective findings and visual function and between OCT findings and changes in visual function after treatment.

Cases and Method:This retrospective study was made on 30 cases of non-functioning pituitary adenoma treated by us during the past 81 months. All the cases received surgical removal of the tumor with histopathological study.

Results:Twenty-two cases showed visual problems, including impaired vision 15 cases, visual field disorder 4 cases, impaired vision and visual field disorder 2 cases, and diplopia one case. Visual acuity improved in 12 cases and persisted in 3 cases after surgery. Visual field improved in 15 cases and persisted in 7 cases after surgery. Eight cases were evaluated by OCT. Two cases showed attenuated horizontal component of circumpapillary retinal nerve fiber layer with thinning of ganglion cell complex in the nasal hemisphere. These two cases showed poor visual outcome after surgery. The other 6 eyes showed normal OCT findings and resulted in fair visual outcome after surgery.

Conclusion:OCT promises to be useful in predicting the course after surgery in non-functioning pituitary adenoma.
