Video abstract of original research "Visual migraine aura with or without headache: association with right to left shunt and assessment following transcutaneous closure" published in the open access journal Clinical Ophthalmology by M Khalid Mojadidi, Hamidreza Khessali, Rubine Gevorgyan, et al.

Conclusion: There is an increased prevalence of PFO among patients with migraine aura without headache. The closure of PFO correlates with improvement of the visual aura, suggesting a causative association between the presence of PFO and both visual aura and migraine headaches. Ophthalmologists should be aware of the association of right to left shunts with visual aura.
