Patient: 60 years old, has had diabetes for 15 years, concerned about deteriorating vision, numbness in feet and hands. There's an infiltrate on the right big toe with marked hyperemia, swelling, and a central necrosis focus, but no pain in the infiltrate area. Drainage was performed, expelling 10 ml of pus. The patient was treated with RT using GI, ZB, and KL emitters. As a result of treatment, the wound healed, sensitivity in the lower extremities significantly improved, the numbness in the toes was reduced by 90% compared to the initial state. An interesting observation was that after 3 weeks of treatment, the patient's vision improved. (She started reading again, although she hadn't been able to do so for nearly 8 years). No side effects were observed.
