Title
"New imaging technologies for the diagnosis and management of glaucoma"
Abstract
With the development and improvement in imaging instruments, objective,
quantitative techniques are now available to assist in the detection
of glaucomatous optic disc and retinal nerve fiber layer damage and
in the monitoring of change over time. With their large amounts of
data and sophisticated analysis capabilities, these new techniques
are likely to influence the future management of glaucoma by providing
information not previously available to clinicians. As the use of
these instruments in clinical practice has increased in recent years,
it is important to understand the advantages and limitations of using
this information for detecting glaucomatous damage and monitoring
its progression. The advantages and limitations of three techniques
for obtaining measurements of the optic disc and nerve fiber layer,
confocal scanning laser ophthalmoscopy using the Heidelberg Retina
Tomograph, scanning laser polarimetry using the GDx Nerve Fiber Analyzer
and optical coherence tomography will be discussed. The sensitivity
and specificity of these imaging instruments for detecting early to
moderate glaucoma will also be compared to visual function tests including
frequency doubling technology and short-wavelength automated perimetry.
