MICROWAVE DIATHERMY IN OPHTHALMOLOGY: CLINICAL EVALUATION
William B. Clark · 1952
This 1952 research shows microwaves were used therapeutically for eye conditions, demonstrating biological effects in vulnerable ocular tissue.
Plain English Summary
This 1952 clinical study evaluated microwave diathermy as a therapeutic treatment for eye conditions, including senile macular degeneration and retrobulbar neuritis. The research represents early medical use of microwave radiation for heating deep tissues to treat various ophthalmological disorders. This work provides historical context for understanding both therapeutic microwave applications and potential biological effects of microwave exposure on human tissue.
Why This Matters
This 1952 study represents a fascinating chapter in medical history where microwave radiation was deliberately used as therapy for eye conditions. While the specific parameters aren't detailed, microwave diathermy typically operates at frequencies between 915 MHz and 2.45 GHz - the same general range as today's cell phones and Wi-Fi. The key difference is intensity and duration: therapeutic diathermy delivers concentrated microwave energy to create controlled heating effects, while modern wireless devices expose us to much lower levels continuously throughout the day.
What makes this research particularly relevant to today's EMF health debate is that it demonstrates microwaves can produce measurable biological effects in human tissue, specifically in the delicate structures of the eye. The eye lacks the blood circulation needed to dissipate heat effectively, making it especially vulnerable to microwave energy - a concern that remains relevant as we consider chronic, low-level exposures from modern wireless technologies surrounding our daily lives.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 15 minutes per treatment, with treatment frequency varying from 3 times weekly for 3 weeks, then 2 times weekly for 6 weeks, then 1 time weekly for 6 weeks
Study Details
To evaluate the clinical effectiveness of microwave diathermy in treating diseases of the posterior ocular segment, with the primary objective being the prevention of further regression and maintenance of vision at a useful level (20/40 or better).

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. The treatment is effective in maintaining vision and preventing further regression in various ocular conditions. No harm was done to the crystalline lens in any case treated with this method, even with extensive treatment protocols. The method allows heating of deeper tissues without undue heating of superficial tissues and provides localized heat control.
