An Analysis of Retinal Nerve Fiber Layer Thickness before and after Pituitary Adenoma Surgery and its Correlation with Visual Acuity

Pituitary adenomas comprise approximately 10% of all intracranial tumors. Initially, subtle changes occur in the field of vision, which are difficult to assess clinically. It has been seen that following surgery of pituitary macroadenoma, total recovery of normal vision occurs in 35% of the patients, improvement of vision occurs in 60%, and in the rest there is no change in vision. Retinal nerve fiber layer thickness (RNFLT) undergoes retrograde...
