Preclinical studies show that SLT does not cause the coagulative damage to the trabecular meshwork caused by Argon Laser Trabeculoplasty (ALT) as shown in Example A above.
SLT selectively targets pigmented trabecular meshwork cells, conserving surrounding non-pigmented cells.
This procedure is SAFE and is NOT associated with any systemic adverse side effects.
What is it?
A direct cross-sectional imaging that allows the doctor to analyze layers of the retina and optic nerve; measuring and monitoring delicate structures and any changes within these structures.
Why is it used?
There are TWO possible reasons for your doctor to order this procedure:
Early detection of glaucoma OR
Monitoring the effectiveness of current therapies in arresting the effects of the disease of glaucoma on your vision.
Does it replace a visual field?
No, it does not. A visual field evaluates your level of visual function. However, the structural damage from glaucoma occurs up to FIVE years PRIOR to the patient experiencing VISION loss. With HRT a personalized visual map of your retina and optic nerve is compared (by computer technology) to the new scan, and any changes are highlighted. Your doctor can immediately see if your glaucoma is progressing and then prescribe needed therapies, BEFORE vision loss is experienced.
