3.3.3.1 Beam delivery in the laser slit lamp
The laser beam is interlaced into the illumination beam path, so
that the slit image and the laser spot can move around the fundus
in synchrony. This ensures that the area of the fundus which is to
be coagulated is always illuminated, even in the peripheral fundus.
This means of combining illumination and laser beams is particu-
larly advantageous for small illumination fields.
