Purpose: To analyze the neuro ophthalmic manifestations of intra cranial tumors.
Methodology: A prospective study of 132 patients seen in neuro ophthalmology clinic from January 2015 to March 2018 with newly diagnosed brain tumor based on their ocular signs.
Results: Mean age was 41.97 yrs. Commonest ocular sign was temporal pallor (40.4%) followed by relative afferent pupillary defect (33.3%), multiple cranial neuropathies (18%) and nystagmus (8.3%). Field defects were seen in 52.6% of patients. Pituitary adenoma constituted 44.9% of all tumors followed by meningioma 26% , acoustic neuroma 12%, craniopharyngioma 9% & brain secondaries 2.3%. There was a statistically significant association between presenting and follow up visual acuity(p<0.001). Conclusion: Ocular signs form a major presentation in the initial stages of certain intra cranial tumors and maybe of great help in early diagnosis thereby allowing localizing and early management of these tumors.
