Proliferative diabetic retinopathy

This study will test a new pattern of retinal laser treatment combined with anti-VEGF injections for people with proliferative diabetic retinopathy (PDR), a serious eye condition that can lead to blindness. Researchers plan to enroll 300 adults aged 18–70 with stable diabetes and…

This study tests a vibrating device to reduce pain during laser treatment for diabetic eye disease. About 50 people will have one eye treated with the device and the other without, then rate their pain. The goal is to see if the vibration helps make the procedure more comfortable…

This study investigates whether the speed at which blood sugar falls after starting a new diabetes medicine affects small blood vessels in the eye. Adults with type 2 diabetes who are beginning a GLP-1 receptor agonist or an SGLT2 inhibitor will undergo advanced eye scans and blo…

This study will test a new, noninvasive camera called XyCAM CRE that measures blood flow in the back of the eye. Researchers will compare its images with standard eye tests in 350 adults with retinal disorders. The goal is to see if this camera can provide extra information to he…

This study will analyze eye and brain scans from over 200,000 people to see if eye images can predict brain diseases like small vessel disease and other health problems. Researchers will build computer models to map eye features to brain structure and disease diagnoses. No treatm…

This study looks at whether argon laser treatment for advanced diabetic eye disease (proliferative diabetic retinopathy) changes the number of cells in the cornea. Researchers will measure corneal cell density before and after laser treatment in 45 patients. The goal is to see if…
