In this prospective clinical study SRT is performed with various pulse durations at 1.7µs and additionally 200ns to evaluate the different clinical effects of both laser regimens. The macular diseases to be treated are drusen maculopathy and geographic atrophy due to age-related macular degeneration as well as diabetic macular edema and central serous chorioretinopathy.
The beneficial effect in laser treatment is thought to be associated with the restoration of a new barrier of retinal pigment epithelium cells. If this theory is true, the destruction of the photoreceptors causing visual field defects would be only an unwanted and unnecessary side effect. Thus, SRT is able to avoid these unintentional side effects and to achieve the benefit by just treating the RPE.
In this study the clinical effect of SRT for these diseases is evaluated on a long-term basis.
