See first-hand how SLT treatment is performed in a number of different clinical cases.SLT: Treatment ProtocolTreatment is undertaken in single shot mode, with consecutive but not overlapping spots placed over the interior half of the trabecular meshwork. To determine the optimal level of energy for each patient, the energy level is gradually increased until the threshold energy level for mini-bubble information is observed, or decreased if bubble formation is noted.
SLT: Narrow AnglesWhen performing SLT on patients with narrow angles, visibility is reduced compared to normal angles. It is important to ensure the patient looks toward the mirror in order to improve visibility. In addition, the laser treatment beam must be applied closer to the iris base, but without touching it.
SLT: Heavily-Pigmented TrabeculumIt is important to note that less energy is required when performing SLT on patients with a heavily pigmented trabeculum. In this case study, extensive mini-bubble formation was noted at the commencement of SLT treatment, indicating that the energy level was too high. The energy level was consequently decreased to be just below the threshold level for bubble formation.
SLT: Irregular PigmentationTip: Always ensure that focus is maintained on the target tissue, and not on the laser beam spot. In addition, the treatment beam should cover the central part of the trabecular meshwork, where pigmentation is maximal.
