Subthreshold Nanosecond Laser for Non-resolving Central Serous Chorioretinopathy

The 2RT™ Q-switched YAG laser (532nm) delivering 3 nanosecond pulses; 400 um spot size, is a pulsed subthreshold nanosecond (SNL) laser, which uses low energy levels to produce limited effects that selectively target melanosomes within the pigmented retinal pigment epithelial (RPE) cells.

Application of sham laser (i.e. flashing lights which replicate the look of active laser to the participant) from the 2RT subthreshold nanosecond laser device.
