A 59-year-old former athlete. Cleared by 3 cardiologists. Saved by sclera analysis.

Patient presented with currents and pain in the left arm and legs. Three cardiologists concluded no cardiovascular issue.

Sclera analysis surfaced a coronary artery blockage — a life-threatening situation. Same-day cardiac mapping confirmed it. Bypass surgery, later that day, saved his life.

"The sclera revealed what the panel missed."
