Excimer Laser Trabeculostomy
Excimer Laser Trabeculostomy (ELT) is a laser therapy that has been under
development since the 1980’s. Similar to other laser treatments for glaucoma,
ELT involves applying a high energy laser beam to areas in the eye to improve
the drainage and flow of fluid in the eye. However, unlike existing treatments,
ELT has shown to be less destructive to surrounding tissue. Furthermore, in
many cases ELT eliminates the need for any medications to control intraocular
pressure after the surgery has been performed. Excimer Laser Trabeculostomy has
been approved for use in the European Union since 1998. Thousands of ELT
procedures have been successful in lowering and maintaining lower IOP for years
in Europe. Currently, clinical studies are pending in both Canada and the
United States, and the next generation of ELT devices is under development.
Travatan Study
The primary objective of this study is to monitor any changes in iris color in
individuals with glaucoma. Subjects must have either open-angle glaucoma or
ocular hypertension, have an iris color change following use of TRAVATAN®, and
must be currently using TRAVATAN®.
Age-related Macular Degeneration Study
Ocular Response Analyzer is a device that was originally intended to measure
intraocular pressure by utilizing a rapid-air impulse and an advanced
electro-optical system. However, it became useful also for determining corneal
tissue properties, such as corneal rigidity. Thicker sclera tissue in the eye
has been correlated with increased risk for age-related macular degeneration.
However, determining the rigidity of the eye has been a fairly invasive
procedure. This study was designed to determine if ocular rigidity could be
ascertained in a non-invasive, non-contact manner using ORA. Subjects will be
asked to come in for one visit. They will undergo slit lamp biomicroscopy, ORA,
measurement of IOP, gonioscopy, dilated fundus exam, fluorescein angiography,
fundus photography, and axial length measurement.
