Neuropathic ulcers develop due to nerve damage (neuropathy), commonly seen in conditions like diabetes, leading to loss of sensation, repetitive trauma, and poor wound healing. These ulcers typically occur on weight-bearing areas, hyperbaric oxygen and polarized light therapies may have a synergistic effect, improving oxygenation, cellular activity, and overall healing outcomes in neuropathic ulcers, particularly in diabetic foot ulcers.

Inclusion Criteria:

• blood pressure (BP) 150/90mmHg.
• Chest X-ray was reported normal
• all patients were clinically evaluated by a specialized ear, nose, and throat (ENT) physician to ensure suitability for the hyperbaric chamber.

Exclusion Criteria:
