Abstract: A laser system for treating target tissue layers of an anterior chamber angle of an eye, including a delivery system and various imaging systems is being disclosed here. The system includes novel configurations using small digital cameras, OCT and other diagnostic devices that are integrated with a goniolens to visualize and target the to be treated tissue layers and that in some configurations remain connected and active during the laser treatment. Furthermore, several novel illumination systems and standalone digital camera goniolens systems are being presented here.
