Impact of time delay to ophthalmology examination on visual outcomes of pediatric brain tumor patients

Children with primary pediatric brain tumors (PBT) may present with, or develop, abnormal visual function, including visual acuity (VA) loss, visual field defects (VFD), and oculomotor abnormalities(1). Visual deficits may go unrecognized until later in life(2). PBT patients may not undergo ophthalmologic examinations for many reasons including limited access, lack of awareness of PBT effects on vision, difficult pediatric examinations, or concentration on treating the PBT without consideration to secondary effects(3). This study evaluated the impact of delayed ophthalmologic examination following initial PBT diagnosis on diagnosing visual deficits and visual outcomes.
