Abstract
Embodiments of the invention provide systems and methods for treating the retina and/or other areas of a patient's eye. The procedures may involve using one or more treatment beams (e.g., lasers) to cause photocoagulation or laser coagulation to finely cauterize ocular blood vessels and/or prevent blood vessel growth to induce one or more therapeutic benefits. In other embodiments, a series of short duration light pulses (e.g., between 5-15 microseconds) may be delivered to the retinal tissue with a thermal relaxation time delay between the pulse to limit the temperature rise of the target retinal tissue and thereby limit a thermal effect to only the retinal pigment epithelial layer. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered within a treatment boundary or pattern defined on the retina of the patient's eye.
