Pituitary adenoma is a benign epithelial neoplasm derived from and composed of adenohypophysial cells. Patients with intracranial pituitary adenomas are most commonly detected by endocrinologists, although the non-secreting tumours may first present to Ophthalmologists. Herewith reporting a case of a huge pituitary adenoma of size 34x23x31mm which presented with the symptoms of an occasional vague, transient blurring of vision during the initial visit with a normal visual acuity, anterior segment and a posterior segment. The clinical importance of recording colour vision apart from the regular evaluation of visual acuity, slit lamp evaluation, intraocular pressure measurement and fundus evaluation in an otherwise asymptomatic patient is stressed in this article. This clinical evaluation is very important in the early diagnosis and patient management which should have far reaching benefits.
