Abstract---Purpose: To evaluate the effects of polarized light therapy versus monochromatic infrared energy in the treatment of venous leg ulcers. Methods of evaluation: - (Measurement of the ulcer surface area (USA) and the ulcer volume measurement (UVM). Methods: Forty patients suffering from stage 2 lower limb venous ulcers were selected randomly from the vascular and general surgeries departments of Kasr-El-Aini Hospital. These patients were divided randomly into two equal groups in number: One was treated with the polarized light therapy (BLT) besides the regular ulcer care (topical and general medications as well as the intermittent surgical curettage) for three months, while the other was treated with the monochromatic infrared energy (MIRE) therapy, medical treatment and the and the regular ulcer care (topical and general medications as well as the intermittent surgical curettage) for three months or till healing, their ages were ranged from 50 to 65 years. Results: Results showed that both the BLT and MIRE were effective in enhancing the healing of the lower limb venous ulcers as manifested by the highly significant decreases in ulcer surface area (USA) and ulcer volume measurement (UVM). MIRE was more fruitful in decreasing the USA but not significant as BLT in decreasing the UVM. Conclusion: Both were nearly equivalent and significantly effective in enhancing the healing of the lower limb venous ulcers as manifested by the highly significant decreases in
