Abstract
A combination of scanning laser ophthalmoscope and therapeutic laser source expands the range of clinical applications of the conventional scanning laser ophthalmoscope, being capable of simultaneous imaging, microperimetry and the delivery of therapeutic laser applications to the retina in a preferred non-contact mode. The combination, including a therapeutic laser source, optic-mechanical Maxwellian view coupling device allowing a similar Maxwellian view entrance location in the eye for both the scanning laser ophthalmoscope and therapeutic laser source, and real-time electronic registration of the therapeutic beam location, permits precise positioning and dosage of the retinal applications. Additional safety mechanisms include a shutter activation based on digital image processing techniques.
