Purpose: To report visual acuity and visual field change in patients with transsphenoidal pituitary adenoidectomy.
Materials and Methods: Twenty-eight patients who had performed transsphenoidal pituitary adenoidectomy for pituitary adenoma were evaluated preoperative as well as postoperative visual acuity and visual field. The patients with preexisting ocular disease or low reliability in visual field test were excluded .
Results: The 23 patients who were diagnosed with pituitary adenoma at the Department of Neurosurgery were consulted to the Department of Ophthalmology and other 5 patients were presented and diagnosed at the Department of Ophthalmology. Bitemporal hemianopsia was most common in 13 of 28 patients with visual field defect. There were 5 patients who had visual defects without decreasing visual acuity. The postoperative improvements of visual field defects were statistically significant in both eyes of all patients (p<0.01). The visual acuity of eye with more poor vision before surgery was significantly improved after surgery (p=0.02).
Conclusions: The improvement was more remarkable in visual field than visual acuity after surgery in the patients with pituitary adenoma. The pituitary adenoma was excluded in the patients visual field defect of variable type because the typical bitemporal hemianopisa was only 46% of visual field defect because of pituitary adenoma.
