Topic: Ocular effects and corneal injury; Automotive-radar frequency research

Verification Group: Original text reviewed

Record Role: Original text reviewed

Featured: False

Exposure: 76 GHz local eye exposure; 10, 50, 75, 100 or 200 mW/cm² for 6 min; focused lens antenna; anaesthetised, held-open rabbit eyes.

Design: Conference proceedings paper; 52 pigmented rabbits across experimental procedures; slit-lamp and ocular-temperature measurements.

Finding: 200 mW/cm² produced opacity, epithelial injury, miosis and inflammation; 75/100 mW/cm² produced reversible epithelial injury.

Statistics: See reported finding and original tables; effect sizes not independently recalculated.

Boundary: No detectable ocular changes at 10/50 mW/cm². Acute high-power hazard experiment, not automotive FMCW exposure. Conference publication type is distinct from a journal article.

Related: Related ocular programme with WEB-022, WEB-012 and WEB-017.

Protection Question: Which exposure conditions and biological models reproduce this response, and what would establish its relevance to health?

Access: Original methods/results sections reviewed; no independent raw-data or supplement audit.
