Greater occipital nerve blocks may alleviate photophobia brought on by migraines
SPAIN: According to a research study published in the Journal of Neuro-Ophthalmology, greater occipital nerve block reduces migraine-related photophobia as judged by the Utah Photophobia Symptom Impact Scale (UPSIS-12) and the Korean Photophobia Questionnaire (KUMC-8).
One of the most unpleasant symptoms experienced by migraine sufferers is photophobia. Up to 80% of migraine sufferers experience photophobia, which can occur between attacks. There aren't many studies looking at how migraine medication affects this symptom. The majority of the proposed therapies for photophobia up to this point have been based on case reports or a small amount of research. In order to alleviate this troublesome sensation, new treatments are still required.
The researchers of this study sought to investigate how levels of photophobia associated with migraines were affected by greater occipital nerve (GON) block.
The researchers carried out a prospective observational case-control study. They sought migraine and photophobic patients who visited a headache clinic. Patients who underwent a GON block while adhering to standard clinical practice standards were considered cases. 41 patients were included in the trial, of which 28 (68.3%) were cases and 13 (31.7%) were controls. All patients were assessed during their initial visit (V1) and one week later (V2) using the Hospital Anxiety and Depression Scale, the Migraine Specific Quality of Life Questionnaire, the Utah Photophobia Symptom Impact Scale (UPSIS-12), and the Korean Photophobia Questionnaire (KUMC-8).
