Inventor’s pursuit: How smartphones can better your health | UW Medicine

Healthcare Inventions and OCTA Technology
🔬 Ricky Wang, 2023 UW Medicine Inventor of the Year, developed OCTA, an eye imaging technique that visualizes microvasculature non-invasively without injected contrast agents.
👁️ OCTA detects red blood cells moving in the eye and is widely used in ophthalmology to diagnose and manage conditions like glaucoma, age-related macular degeneration (AMD), and diabetes.
💡 Wang's current research extends beyond the eye, focusing on imaging vascular involvement in skin cancer and internal organs like the stomach and colon to control blood supply.

Smartphone-Based Diagnostics
📱 A new direction in Wang's lab involves using smartphone technology to capture images of the mouth (gums/teeth).
🦷 The resulting image shows a red glow where bacterial load is high, indicating the need for more diligent brushing.
🌍 The ultimate goal of this smartphone research is to improve healthcare systems, particularly in low-resource settings.

Key Points & Insights
➡️ OCTA technology is a significant advancement in ophthalmology, enabling non-invasive imaging of the eye's microvasculature.
➡️ Future innovation leverages existing smartphone cameras to provide accessible, low-cost diagnostic screening for issues like high bacterial load in the mouth.
➡️ Research efforts are strongly focused on improving patient quality of life through practical, accessible diagnostic tools.
