The baseline characteristics between TNF-α-positive and TNF-α-negative groups were similar in terms of age, history of migraine, history of cold extremities, axial length, central corneal thickness, mean follow-up IOP, baseline average pRNFL thickness, baseline average mGCIPL thickness, baseline MD and PSD, presence of DH, and presence of central scotoma. This evidence concerns the gene TNF and migraine disorder.
