Clinical technique and results on some cases treated with a new photocoagulator using the Goldmann contact glass and a quasi-continuous ruby laser as an energy source are reported. It is shown that small burns can be positioned exactly out to the far periphery of the retina using very low pulse energies. The coagulator is mounted on a Haag-Streit table and patients can easily be treated in an upright position. A discussion of the coagulation strategy to be followed when generating multiple small welds is given. The advantages of this procedure are pointed out.
