# WEB-017 — Corneal drying during high-power 162 GHz exposure

Why this matters
Tissue condition changes how energy is absorbed. This experiment observes drying of the eye surface during a high-power exposure, alongside measurements intended to improve dosimetry.

Topic: Ocular effects and corneal injury; Sub-terahertz biological responses

Verification Group: Original abstract reviewed

Record Role: Original abstract reviewed

Featured: False

Exposure: 162 GHz; 360 or 480 mW/cm² for 6 min; eye-surface temperature rise around/above 5°C associated with drying.

Design: Rabbit-eye in-vivo reflectance/OCT measurements alongside in-vitro corneal dielectric measurements.

Finding: Changing reflectance was attributed to drying of tear film and corneal epithelium as temperature increased.

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

Boundary: Original abstract only; high-power thermal response and dosimetry study. No direct communications-system experiment and no quantified population risk.

Related: Japanese ocular research programme; related to WEB-012 and WEB-022.

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

Access: Original abstract and bibliographic metadata checked; full methods and dosimetry not audited.
