Location - The Center is housed in three 650-square-foot laboratories and two 120-square-foot offices, plus administrative space in
Lewis Hall, the major medical research building at EVMS. An additional 120- square-foot
office is available to house the confocal microscope. The electron microscopy suite is
located on the same floor. An AAALAC approved vivarium is housed in the same building; the EVMS library
is next door. Clinical facilities are located across the street on the EVMS Medical
Center Campus and include facilities for both inpatient and out-patient surgery and
follow-up care, both at the Lions Sight and Hearing Center and in ophthalmologists
private offices.
Equipment - The laboratories are equipped with a surgical suite for small animal
surgery, operating instruments, specular microscope, small operating microscope and
binocular microscopes, fluorescent microscope, a microtome for preparing frozen sections, HPLC, spectrophotometers, fluorometers, ultracentrifuges, scintillation and gamma
counters, digital photography, data logging and analysis, portable slit lamp, laminar flow
hood, tissue incubators, refrigerators, and 90 degree C freezers.
Confocal microscope - An ophthalmological confocal microscope manufactured by
Advanced Scanning, Ltd., has been requested to permit evaluation, quantitation, and
documentation of the projects proposed by our research group. Confocal microscopy has a
number of benefits when compared to standard light microscopy. It permits resolution of
discrete optical sections through cells, which allows reconstruction of the cell in three
dimensions. This is crucial in revealing changes in the integrity of the epithelium and in
the relationship of the various cell layers to each other in the cornea and to determine
damage in other ocular structures, such as the optic nerve. The ability to determine
discrete optical sections also is useful in reducing the blurring caused by light produced
out of the focal plane that occurs when fluorescent probes are used. Reduction of this
blurring enhances the localization of fluorescent probes, such as those labeled antibodies
used for immunocytochemistry and fluorescent microbeads that will be used for
determination of aqueous humor flow.
Unlike other high-resolution techniques such as SEM or TEM, confocal microscopy can be
performed on living cells, permitting longitudinal studies on the same subject. This
particular confocal microscope is unique in that in can be used for both patients and for
isolated cells or tissues. To take full advantage of the confocal microscope, it will be
used in conjunction with specialized image processing software that will permit
reconstruction of 3-D images, determinations of optical haze and the quantitation of
antibody labeling and other intracellular probes. A highly sensitive digital camera and
computerized data collection system will be used to collect, process, and store these
images.
