Ocular Laboratory for Analysis of Biomarkers: using the eyes as a window to health.
OCULAB (Ocular Laboratory for Analysis of Biomarkers) is an ARPA-H research program exploring continuous health monitoring and treatment through tear biomarkers. Its initial target is dry eye disease. The program’s two technical areas are a continuous nanosensor for the tear duct and closed-loop therapeutic dosing. Tear-based measurements could eventually support monitoring beyond eye conditions, while the envisioned system would use biomarker readings to guide personalized treatment. In 2026, ARPA-H announced awards to four research teams developing different sensing approaches for dry eye disease and other conditions.
