1. Ability of Cirrus HD-OCT Optic Nerve Head Parameters to Discriminate Normal from Glaucomatous Eyes

    Ophthalmology (Oct 3 2010) Journal Articles , Glaucoma

    1. To determine the ability of optic nerve head (ONH) parameters measured with spectral domain Cirrus HD-OCT (Carl Zeiss Meditec, Inc., Dublin, CA) to discriminate between normal and glaucomatous eyes and to compare them with the discriminating ability of peripapillary retinal nerve fiber layer (RNFL) thickness measurements performed with Cirrus HD-OCT.

    "I read with interest the study "Ability of the Cirrus HD-OCT Optic Nerve Head Parameters to Discriminate Normal from Glaucomatous Eyes" Ophthalmology (article in press)

    According to this study the rim area seems to be a very good parameter in distinguishing normals from glaucoma (especially early glaucoma)

    I am just wondering when it would be said that the rim area is low or adequate since it is not included in the normative database of the machine. Will Cirrus HD-OCT soon come out with a normative database for rim area soon?

    Thank you

    "Dear Dr. de Leon- Thank you for your comment! And to answer your question, with our current Cirrus HD-OCT software, version 5.1, Optic Nerve Head parameters, including rim area, are compared to normative data. Please email us at zeissoct@meditec.zeiss.com and we can email you in return an example of the RNFL ONH printout to explain in further detail. Thanks again - ZEISS OCT"
