摘要
The present invention provides devices and methods for applying radiation to the retina of a patient. In one embodiment, an apparatus includes a radiation source for generating a radiation beam suitable for absorption by retinal pigment epithelial cells. One or more optical components are included to direct the beam onto the retina. A scanner is optically coupled to the radiation source to control movement of the beam in two dimensions to allow a scan over the retina. A controller applies control signals to the scanner to adjust beam movement to illuminate a plurality of retinal locations in a temporal sequence according to a predefined pattern. The device can be operated in one mode to effect selective targeting of retinal pigment epithelial cells, or in another mode to effect thermal photocoagulation of the retina.
