An interesting case of a 58 yr old male presented with defective right sided field of vision. 2 years back,he contracted acute weight gain,muscular weakness,fatigue,episodic flushing and visual loss in both eyes on temporal field of view.He was diagnosed as a Cushing disease due to pituitary macroadenoma and underwent trans-sphenoidal surgery for tumor removal, was asymptomatic for 3 months and experienced improvement in field defect,not resolving fully.After 3 months,he developed defective vision in right field of vision in both eyes.MRI revealed metastasis to Lt parietal lobe,subsequently treated with EBRT. Current visual acuity is 6/6p in both eyes.Both eyes showed disc pallor.HFA 30-2 showed Rt. sided homonymous hemianopia with LE showing involvement of temporal field. Thus Serial monitoring of visual fields in intracranial causes of visual field loss should be mandatory.
