Use of Blue Light in the Management of Chronic Venous Ulcer in Asian Patients: A Case Series.

Chronic venous ulcers, often complicated by late diagnosis and persistent infections, present major clinical and financial challenges. Recently, photobiomodulation therapy (PBMT) has been shown to be effective in overcoming physiological impairments such as hemostasis and inflammation, accelerating the wound healing process. This case series summarises our experience in the treatment of two Asian patients with lower-extremity chronic venous ulcers using PBMT with blue light. Case 1 was a 71-year-old male with a history of hypertension, chronic venous insufficiency and previous deep vein thrombosis. Prior to blue light therapy, the average duration of treatment until wound closure with compression dressings used to be 10-12 weeks. Complete wound closure with the blue light therapy was eight weeks, with a total reduction of 67% of wound size by week 4. Case 2 was a 77-year-old male with a background of hypertension and ischaemic heart disease. Prior to blue light therapy, the patient had also underwent iliac venoplasty and stenting for his recurring bilateral malleolus venous ulcers. By week 4, the right malleolus wound had healed, while the left malleolus wound had a size reduction of 38%. Complete closure of both the wounds was noted at week 6. Blue light was administered to the wounds of both patients for 120 seconds per session, as an adjunct to compression therapy. Both patients reported no additional wound pain during the administration of blue light therapy, with an overall reduction of wound pain at three weeks. The cases demonstrated that PBMT with blue light was well-tolerated, safe, and efficacious in improving wound healing with an adjunct to standard treatment of chronic venous ulcers.
