Abstract
An improved method and apparatus for photocoagulation of the fundus of a patient's eye eliminates the contact lens and provides for binocular viewing. The technique is characterized by the utilization of a common ophthalmoscopic lens for each of the illumination beam, the observation beam, and the laser beam. A scanning mirror for the laser beam is disposed on the optical axis and is rotatable in two dimensions about a fixed point which is conjugated with the nodal point of the patient's eye with respect to the ophthalmoscopic lens. The binocular viewing paths are converged onto a point on the optical axis in the plane of the first aerial image of the fundus provided by the ophthalmoscopic lens; the laser beam reflected by the scanning mirror is also focused onto that point.
