Paper Abstract

The confocal scanning laser ophthalmoscope, cSLO, can be used for microphotocoagulation of the retina. For this purpose, external and non-scanning therapeutic laser sources are coupled with the instrument. An opto-mechanical coupling device is calibrated to obtain the same Maxwellian view entrance location in the eye for both scanning and external lasers. Two separate but synchronized confocal detection pathways are capable of monitoring the progression of thermal laser applications on the retina. Real-time image processing is further used to indicate the position and size of the aiming beam on the retina. This aiming beam can be pulsed in anti-aliased fashion with regard to its confocal detection, to allow for higher intensities. Its polarization is exploited to sharply reduce corneal reflections. MInimal optical distribution of the therapeutic laser beam, full documentation of application characteristics, simultaneous microperimetry, infra-red and angiographic imaging are useful features to guide microphotocoagulation.
