Microwave diathermy in ophthalmology -- Clinical evaluation
Clark WB · 1952
1952 medical research used microwaves therapeutically for eye treatment, showing early recognition of microwave biological effects.
Plain English Summary
This 1952 clinical study examined the use of microwave diathermy (therapeutic heating) for treating eye conditions, including macular degeneration and retinal disorders. The research represents early medical applications of microwave energy in ophthalmology. This historical work provides insight into how microwaves were first used therapeutically, decades before concerns about EMF health effects emerged.
Why This Matters
This 1952 study represents a fascinating historical perspective on microwave technology in medicine. While doctors were exploring microwaves as therapeutic tools for eye conditions, they had limited understanding of potential biological risks from electromagnetic field exposure. The research highlights an important irony: the same microwave frequencies later found to cause cellular stress and potential health effects were being deliberately applied to treat medical conditions. What makes this particularly relevant today is that microwave diathermy uses similar frequencies to modern wireless devices, yet the therapeutic applications required much higher power levels for heating tissue. This early medical research demonstrates that the biological effects of microwaves have been observable since the 1950s, though the focus was on beneficial heating rather than potential harm from lower-level chronic exposure.

Exposure Information
Specific exposure levels were not quantified in this study. Duration: 15 minutes per treatment, 3 treatments weekly for 3 weeks, then 2 treatments weekly for 6 weeks, then 1 treatment weekly for 6 weeks
Study Details
To evaluate the clinical effectiveness of microwave diathermy in treating diseases of the posterior ocular segment, particularly focusing on maintaining visual acuity at a useful level (20/40 or better) rather than restoring vision to normal.
Microwave diathermy was administered using a Raytheon Microtherm triangular applicator at a distance...
Results were encouraging for senile macular degeneration, retrobulbar neuritis, central serous retin...
Microwave diathermy offers a simple and rational method of treating diseases of the posterior ocular segment when maintenance of visual acuity at a useful level (20/40) is used as a criterion of success. It has been employed with generally encouraging results in secondary senile macular degeneration, retrobulbar neuritis, central serous retinopathy, certain thrombotic and hemorrhagic conditions, and postoperative uveitis. The method appears to be safe with no lens damage observed in any cases treated. The technique allows heating of deeper tissues without undue heating of superficial tissues, and the temperature of the vitreous can be raised to a therapeutic degree (103°F) when used correctly.
