Abstract

Rabbits were irradiated with 2450-MHz continuous microwave energy. Effects of the radiation on the ocular lens were assessed by slit-lamp biomicroscopic examination of the eye. Two lenses were selected for electron microscopy, one that was severely damaged and one that appeared unaffected by the radiation. There were prominent ultrastructural changes in both lenses.

Main findings

Rabbits were exposed to 2450-MHz continuous microwave radiation and lens effects were assessed by slit-lamp examination. Electron microscopy of two selected lenses (one severely damaged by slit-lamp exam and one appearing unaffected) found prominent ultrastructural changes in both lenses.

Outcomes measured

Ocular lens damage
Ultrastructural (electron microscopy) changes in the lens

Limitations

Sample size not reported in abstract
Only two lenses were selected for electron microscopy
Exposure metrics beyond frequency (e.g., power density/SAR, duration) not reported in abstract
Selection of lenses for electron microscopy may introduce selection bias
