An Unusual Cause of Pseudopapillary Oedema: Hyperphosphatemic Hyperostosis Syndrome

Abstract

For the first time, we report hyperphosphatemic hyperostosis syndrome as a cause for pseudopapillary oedema in a pediatric case. Clinical findings are presented and discussed with tomographic evaluation (optical coherence tomography and Heidelberg retinal tomography) of optic discs, visual-evoked potentials, and visual fields.
