Course of pattern-reversed visual evoked cortical potentials in 30 eyes after bony orbital decompression in dysthyroid optic neuropathy

Abstract

After decompression surgery, DON remission was observed in all patients regarding vision and VECP amplitudes. New or persistent P100 latency defects were seen in 60% of eyes after surgery. DON is considered to be caused by compressive ischaemic damage, which further underlines the importance of early decompression surgery.
