Cirrus 5000 Vs 6000

  • To manage glaucoma, OCT is a must-have technology and one of the biggest hurdles practitioners face when adding care of this disease to their practices. The devices provide sophisticated detail on anatomical status and disease risk, but the sheer volume and complexity of the data can be daunting, as there are features and reports galore that can easily overwhelm us.
  • Due to the close proximity of our office, the venue was perfect for a comparative demonstration. This patient accompanied us into the exhibit hall to be tested on each instrument with all of the glaucoma modules available: optic nerve head (ONH), retinal nerve fiber layer (RNFL), macula and OCT angiography (OCT-A).
  • His intraocular pressure (IOP) ranges from 15mm Hg to 19mm Hg, and he had a slightly thinner cornea of 515µm. He has larger than average vertical cup-to-disc ratios of 0.65/0.60 OD/OS with a noticeably thinner superior temporal rim OD and RNFL wedge defect visible on fundus photography and confirmed with our in-house OCT.
  • During the Academy 2019 meeting in Orlando, I recruited Ed Searl— a recently diagnosed glaucoma patient who also happens to be the optician at my practice—to join me in the exhibit hall and be scanned by all the OCT devices available.
