Abstract

Overview

The extensive use of mobile cell phones today raises concerns due to the potential effects of microwave (MW) radiation, particularly on ocular health. This experimental study investigated the impact of GSM cell phone radiation on the retina of rabbits.

Methods

Study Population: 40 adult white New Zealand rabbits.
Procedure: Randomized into five groups:
- Group 1: no irradiation (sham)
- Group 2: irradiation at 10 cm for 1 day
- Group 3: irradiation at 30 cm for 1 day
- Group 4: irradiation at 10 cm for 3 days
- Group 5: irradiation at 30 cm for 3 days
Data Collection: Scotopic and photopic electroretinography (ERG) responses before and 7 days after irradiation.
Analysis: Kruskal-Wallis and Chi-Square tests to evaluate intergroup differences.

Findings

ERG responses analyzed 7 days post-irradiation showed:

No statistically significant differences among the groups (P > 0.1).
Non-significant trends suggesting greater changes in MW irradiated eyes.
Pathological examinations revealed normal retinas with no degeneration but noted ciliary body congestion particularly in groups exposed to higher doses of MW (P = 0.005).

Conclusion

While mobile cell phone MW irradiation did not significantly impact the retina, it led to increased ciliary body congestion in rabbits exposed to higher MW doses. This highlights a potential risk factor that must be further studied to understand its implications on ocular health in relation to EMF exposure. Caution is advised until more conclusive data is acquired.
