Hi, Hoover.
Would you please post this notice on CVNet?

The Foundation for Vision Science invites research proposals from North
American laboratories. We offer for scientific use a Rodenstock Model
101 scanning laser ophthalmoscope (SLO), training in such use, but no
funds. The instrument will become available by May 1, 1999. The
Foundation is primarily interested in basic research and the development
of the technology of retinal imaging and vision science. Invitations
from locations that are not very far in travel time from the San
Francisco Bay Area are especially encouraged to apply, in order to
simplify maintenance.

Our SLO is ëfully loaded.í It includes an argon laser, an infrared
diode laser, and a computer-and AOM-controllable helium-neon (633nm)
laser. There are filters for both indocyanine green and fluorescein
angiography. Thus, this SLO can be used for fluorescent imaging as well
as visual function testing and eye movement studies.

The software controlling the pixel-by-pixel modulation of the
helium-neon laser raster display onto the retina consists of primitive,
1980s vintage binaries enabling kinetic perimetry and crude static
perimentry. However, your existing display control software may be used
if it drives a video board that can be slaved to an external video sync
signal and if it outputs RS-170 or NTSC video.

Three of the Foundationís special interests have been (1) small eye
imaging using the technique of acridine orange fluorography described in
IOVS by Nishiwaki et al. in 1994 and following the inspiring work of
Harry Zwick at Brooks Air Force Base in his studies of a garter snake
eye, (2) eye movement measurement/image stabilization by image
processing of video sequences and (3) posterior pole blood flow
measurement by dye-dilution quantitation. Proposals across a range of
basic or adventuresome translational research are welcome.

The Foundation's SLO involves ocular light exposure levels that enable
sustained exposure times, according to ANSI standards. According to the
manufacturer, this SLO is approved for routine clinical use. However,
like other display technologies, its use at your institution in human
studies would likely be subject to Institutional Review Board approval.
