    Laser trabeculoplasty suitable for all open-angle glaucoma patients

    SLT therapy provides a safe and efficacious first-line treatment option for open-angle glaucoma patients who have had little success after taking conventional topical therapy.

     

    Seeing the advantage

    The system is a combined unit that consists of two lasers—a ND:YAG and SLT laser—used for different applications. As the ND:YAG laser has penetrative properties, it is best utilised in the treatment of diseases in which there is a need to create a hole or incision in tissue.

    For example, the laser is used during iridotomy and in the treatment of secondary cataract or limited regional haemorrhages. For the latter, the creation of a small hole allows blood to move into the vitreous humor, where it can be absorbed without detriment to ocular health.

    In contrast, the SLT laser stimulates tissue rather than cutting through it. As such, when applied to an eye with open-angle glaucoma, the laser stimulates the pigmented trabecular cells and macrophages responsible for filtering and draining the aqueous humor, thus triggering a clearance process in the trabecular meshwork,3 which, in turn, lowers the elevated IOP seen in open-angle glaucoma.
