This has been a very interesting discussion, one I am sure that would garner much interest at the 2012 OPS Annual Program. Would be great if one of the participants could write this up in abstract format and submit to the Scientific Paper Session in Chicago. If you're "on the fence" write up a rough draft, send it to me. I will forward it to the Scientific Session Committee and we can help mentor you through the process. Use the link below for direct access to submit the abstract to the OPS website or email me your "draft" and a member of the committee will contact you. http://www.opsweb.org/events/event_details.asp?id=166481 Thanks, bob From: optimal-bounce@xxxxxxxxxxxxx [mailto:optimal-bounce@xxxxxxxxxxxxx] On Behalf Of Gianfranco Ventura Sent: Thursday, October 27, 2011 6:58 PM To: optimal@xxxxxxxxxxxxx Subject: [optimal] Re: Can we measure choroidal thickness? well, you can use the caliper function it won't give you the thickness alongside the scan but you can set it multiple times. beside I am not sure there is a mean value for choroidal thickness (?) I know that it varies depending on the location and patient age (?) and in myopic patients >>> sandor ferenczy <sandorferenczy@xxxxxxxxx> 10/27/2011 2:17 PM >>> There is no automated way to measure the choroid on the Spectralis. We delete the automatic lines, and re-map BM and the anterior sclera - a time consuming process, but it works. Depending on what exactly you are looking for, you may be able to get away with re-mapping only one individual scan out of a series. -sandor Sandor Ferenczy, CRA, OCTc Ophthalmic Photographer Ocular Oncology Service Wills Eye Institute 840 Walnut Street, 14th Floor Philadelphia, Pa 19107 www.fighteyecancer.com On Oct 27, 2011, at 11:07 AM, Callahan, Charlene wrote: > Greetings; > We have been asked to measure choroidal thickness on the Spectalis (5.3.2.0, > Eye Explorer v 1.6.4.0) using an EDI scan.
