PP179 : OPHTHALMOLOGIST’S ROLE IN TRAUMATIC CHIASMAL SYNDROME – A LIFE SAVING MEASURE

Dr.NITHIYA SELVARAJ

A 26 year male presented with complaints of double vision since accident and severe closed head injury. On ophthalmic examination, his BCVA both eyes were 6/6. Anterior segment examination was unremarkable except sluggishly reacting pupil. Ocular motility was full. On fundus examination bow-tie pattern optic atrophy noted. On visual field testing dense bitemporal hemianopia was present. Double vision was confirmed with diplopia charting. CT Brain axial view showed linear fracture extending from left orbital roof to the basi-sphenoid due to vector force by the impact of injury which hinted to the diagnosis and for further investigations. Patient’s pituitary function was normal. Diplopia was explained using Hemifield Slide Phenomenon, a treatable non-paretic form of diplopia.This case is presented for its rarity, highlighting the treatable cause of diplopia for better quality of life and ophthalmologist’s role in screening for panhypopitutarism in these patients as a life saving measure.
