PERG as a visual prognosticator in chiasmatic tumours
Pattern electroretinogram (PERG) allows assessment of ganglion cell function and may therefore be used to assess anterior visual pathway dysfunction. This prospective non-randomised study assessed PERG before and after surgical removal of tumours in and around the sellar region compressing...
Macular slippage following macular hole surgery
