SEATTLE-Kubota Vision, a clinical-stage specialty ophthalmology company and a wholly-owned subsidiary of Kubota Pharmaceutical Holdings Co., announced last week that the company and Joslin Diabetes Center have entered into a material transfer and collaboration agreement for Kubota's Patient Based Ophthalmology Suite (PBOS), in-home optical coherence tomography (OCT*1) device. Joslin Diabetes Center is conducting two clinical studies to evaluate the ability of PBOS to identify cases of diabetic macular edema that may need treatment compared to a commercially-available OCT device.
