Public Workshop - FDA/American Glaucoma Society Workshop on the Validity, Reliability, and Usability of Glaucoma Imaging Devices, October 5, 2012

The Food and Drug Administration (FDA) is announcing a public workshop entitled “FDA/American Glaucoma Society Workshop on the Validity, Reliability, and Usability of Glaucoma Imaging Devices.” The topic to be discussed relates to imaging of the posterior segment of the eye (e.g. retinal nerve fiber layer, optic nerve head, ganglion cell layer) using Optical Coherence Tomography (OCT, time-domain and spectral-domain), with particular emphasis on normative databases and the diagnostic performance of OCT for therapeutic glaucoma products (regulatory considerations) and clinical decision making (clinical practice considerations).

The purpose of this workshop is to discuss issues related to the use of OCT technology (time domain and spectral domain) in the diagnosis and treatment of glaucoma. In addition, we will discuss approaches to verify/validate new diagnostic technologies as well as normative/reference databases and how they impact the diagnostic use of OCT devices.

Date, Time and Location

This workshop will be held October 5, 2012, beginning at 8:00 am at the following location:

FDA White Oak Campus
10903 New Hampshire Avenue
Building 31 Conference Center (Great Room, Sections B & C)
Silver Spring, MD 20993

The workshop will be webcasted.

Registration to Attend the Workshop

To register for the workshop, please visit the American Glaucoma Society (AGS) website.

AGS will charge a registration fee to cover its share of the expenses associated with the workshop. The registration fee is $200 for AGS members and $300 for non-AGS members. Registration is available on a first-come, first-served basis. Persons interested in attending this public workshop must register online by September 17, 2012. Early registration is recommended because facilities are limited and, therefore, FDA may limit the number of participants from each organization. If time and space permits, onsite registration will be available beginning at 7:30am on the morning of October 5, 2012. AGS will charge an on-site registration fee of $400.
