Any one of these discussion topics (conj/iris FA, 25% vs. 10% fluorescein, etc)
would be a perfect fit for "Pearls, Tips & Tactics" a new course the OPS is
offering at the annual meeting in New Orleans on Sunday, November 17th from
11:00 - 12:30 at the Intercontinental Hotel.
This will be a short paper session of a variety of practical topics. Opinion,
discussion and debate is welcome. Presentations can be based on experience and
opinion; in other words it doesn't have to be a "scientific" paper. Cool photos
would be a plus!
If you know you will be in NOLA for the annual meeting and have a topic idea,
let me know. We have 2 more days to get your name listed in the program. After
that, topics/speakers are still welcome, you just won't be listed in the
advance program.
I hope you'll all consider about presenting/sharing during this session.

Katherine,
If you are doing a dark iris, no iris vessels will be visible with FA,
unless there is something obvious, like rubeosis. For conjunctival FA,
turn power way down and watch the exposure on the monitor. The first
JOPS had an article by Csaba Martonyi about a conjunctival FA done with
a Zeiss slit lamp.
Fluorescein Angio-Photography of the Conjunctiva, Martonyi CL. 10/1978
Vol 1:1 p.14 PDF (96k) (should be accessible on the OPS website).
The Topcon retinal camera gives good anterior segment sharpness (better
that the Zeiss FF-3, don't know about the current Zeiss cameras). I
use either 35 or 20 degrees depending. Like Sandor, focus by moving
the base. If the knob is focused all the way anterior, more mag and
sometimes more distortion and less resolution. All the way posterior,
less mag, less distortion and more resolution. The lower magnification
can be compensated for zooming on the monitor.
