Objective- To determine pre and postoperative visual acuity, optic nerve changes in sellar, suprasellar tumors and to assess its prognostic role Material and method-Medical records of 50 patients were retrospectively reviewed for detailed history, complete ophthalmic assessment, visual fields and CT/MRI findings. Results-According to preoperative visual acuity in worse eye patients were divided in 4 Groups- Group I (24%) 12, group II (44%) 22, Group III ( 18%) 9 and Group IV (14%) 7. Visual field defects were subdivided in Group A (14 %) 7, Group B (68%) 34 and Group C (18%) 9 cases. Visual acuity improved in (80%) 40, visual field in (66%) 33 cases. Conclusion: The clinical improvement in such cases depends on structural and functional status of visual apparatus before and after surgery. Definite correlation was found between duration of symptoms and optic nerve head changes, which signifies complete ophthalmic evaluation and its prognostic role besides size and site of tumour
