Retinal Scan May Diagnose PAH

Trial Objectives

---

Pulmonary arterial hypertension, or PAH, is a serious condition where blood pressure in the lungs is unusually high, forcing the heart to work harder. The current best way to diagnose PAH is an invasive procedure called a right heart catheterization, which is not typically approved just for early diagnosis. The delay in diagnosis leads to worse health outcomes, so researchers are investigating a new way to potentially detect PAH earlier using a retinal scan to measure blood pressure in the eyes.

Volunteers in this study will receive retinal scans to look at the blood vessels in their eye and will receive blood testing. These tests will be repeated over two clinic visits to help track changes in the blood vessels, which will help researchers determine if this data can predict if PAH will develop or worsen over time.
