Local Anesthetic Therapy in a Patient with Primary Headache and Lipid Keratopathy

Abstract

A headache is characterized as a craniofacial pain that may derive from any involvement of the structure of the head, neck or cranial cavity. It may be associated with any pathology, negatively affecting the quality of life of the individuals afflicted by it. We present the case of a woman with bilateral lipid keratopathy associated with a headache of a moderate to severe intensity, refractory to treatment with non-steroidal anti-inflammatory drugs, treated with lidocaine 1% injections in supraorbital and infraorbital nerves. A clear improvement was observed in visual symptoms and headache with a decrease in symptom frequency, duration and intensity. The improvement lasted over 6 months, which positively impacted the patient’s quality of life. The treatment was well tolerated and no adverse effects were observed. In this case, local injections of lidocaine showed a favorable outcome. Well-designed studies should be conducted to elucidate the role of LA for this condition.
