Optic Nerve Head Drusen: The Relationship Between Intraocular Pressure and Optic Nerve Structure and Function: Comment

In their article, Nolan et al (1) retrospectively reviewed the records of 236 eyes of 146 patients with optic nerve head drusen (ONHD). The authors found no correlation between intraocular pressure (IOP) and perimetric mean deviation (PMD) as assessed by either Octopus or Humphrey automated perimetry. They found no correlation between IOP and mean retinal nerve fiber layer (RNFL) thickness. Based on these observations, they concluded that, '…lowering IOP in normotensive eyes may not be beneficial in preventing vision loss in patients with ONHD.'
