Visual prognosis after transsphenoidal surgery for pituitary adenoma and its relationship with retinal nerve fibre layer thickness

Abstract

Purpose: To report a case of pituitary adenoma showing the prognostic correlation between retinal nerve fibre layer analysis by OCT and the final postoperative visual result. Methods: A 55‐year‐old female patient with loss of visual acuity in the right eye. During the clinical study a pituitary adenoma was found. OCT showed greater involvement of the retinal nerve fibre layer of the right eye. It was decided to perform surgery to remove the adenoma. Results: A greater improvement is obtained in the left eye than in the right eye after surgery. This result was expected according to the range of involvement shown in the pre‐surgical OCT. Conclusions: OCT is a rapid, non‐invasive, quantitative and objective method for measuring this parameter, which is why this tool has been shown to be fundamental in the follow‐up of these patients and in making decisions such as the appropriate time to operate. The greater the involvement of the retinal nerve fibre layer, the worse the visual prognosis of each eye.
