Zeiss Cirrus HD-OCT


Cirrus HD-OCT enables your optometrist to perform multiple analyses for glaucoma.

The three most common tests are:

  • Retinal Nerve Fibre Layer (RNFL) Analysis reveals the thickness of the layer of the retina that contains nerve fibres that travel up the optic nerve. If glaucoma is present, that layer may gradually lose thickness.
  • Macular Thickness Analysis examines the condition and thickness of the macula, which is the part of the retina that provides central vision. Thinning of the macula is a possible sign of glaucoma progression.
  • Optic Nerve Head Analysis reveals the structure of the optic nerve where it originates in the retina. With glaucoma, the “cup” in the optic nerve may enlarge.
