Focused Ultrasound for Intraocular Hemmorhage

Intraocular hemorrhage is the most common cause of sudden vision loss from advanced diabetic eye disease. This occurs when blood from diseased retinal vasculature leak into the normally clear, gel-like substance in the eye called the vitreous, obscuring vision. The current management guidelines for these patients is a period of modified bedrest (up to 4 months) to encourage natural reabsorption. Apart from “watchful waiting”, the remaining treatment options are surgical. Focused ultrasound (FUS) represents a potential nonsurgical alternative to accelerate clearance of intraocular hemorrhage, and the present study aims to elucidate the biologic and mechanical effects of FUS through preclinical models of intraocular hemmorhage.

The FUS Lab at Sunnybrook Research Institute is 1 of 7 Centers of Excellence in FUS research worldwide, and Vitreosonic Inc. is excited to partner with this local academic powerhouse to assist in performing the rigorous scientific activities necessary to support the development of this sight-saving device.
