Approach to “Visual Loss”
Published in Vivek Lal, A Clinical Approach to Neuro-Ophthalmic Disorders, 2023
Aastha Takkar Kapila, Monika Singla, Vivek Lal
TMVL can also be caused by retinal artery vasospasm in patients of migraine and is called retinal migraine. Retinal migraine is the single commonest cause of transient monocular blindness in young adults less than 40 years.3 Attacks of retinal migraine may mimic amaurosis fugax. While it is claimed by some researchers that “there are no distinguishing symptoms to separate retinal migraine from Amaurosis fugax due to retinal embolization”; others have noted that visual loss associated with retinal migraine is usually of longer duration and the evolution is slower. Moreover, the typical shade dropping over one visual field described by many patients who have amaurosis fugax has not been described in patients with retinal migraine.

Retinal migraine is an interesting but rare entity that may manifest as episodes of monocular scotomata or blindness associated with headache and usually resolving within an hour. Interestingly, onset may be acute10 and recurrent episodes may lead to permanent visual loss.12

Patent foramen ovale is a remnant of the fetal circulation, which normally closes within the first year of life. However, being the most common congenital heart defect, it persists as a cardiac communication between the left and right atria in 20% to 30% of the general adult population. In most people, it remains asymptomatic and therefore unnoticed for life.17 However, studies have shown that there is a possible connection with PFO and migraine and embolic events.17 In our case, our patient had a small PFO. The imaging studies we ran did not show any evidence of a possible embolus that might have predisposed by the presence of PFO. Therefore, we do not think that the patients’ complaints were directly linked to the PFO. Also, our patient has no personal or family history of migraine or aura before or after, and the one we report is the only episode, which has very close time link to vaccination. Also, the visual complaints of the patient lasted longer than a usual migraine aura. Based on these, we think that aura without migraine type headache or retinal migraine are less likely diagnoses in our case.
The eye in migraine: a review of retinal imaging findings in migraine
Published in Clinical and Experimental Optometry, 2022
Allison M. McKendrick, Bao N Nguyen
As a primary headache disorder, the brain in migraine has unsurprisingly received considerable attention in the scientific literature. It is not the purpose of this review to discuss the plethora of evidence for cortical involvement in the pathophysiology of migraine (see e.g. reviews8–12 for recent perspectives on this topic). Instead, here we focus on the ocular involvement and potential ocular sequelae of migraine, with a specific focus on recent studies that have utilised modern ophthalmic imaging. Figure 1 schematically illustrates current models of the pathophysiology of migraine, noting the logic for considering retinal/ocular involvement. While it has long been recognised that migraine can involve the eye (the relatively uncommon cases of ‘retinal migraine’,3) recent advances in ophthalmic imaging have inspired numerous studies investigating whether the common forms of migraine (migraine without aura, migraine with aura) also manifest retinal abnormalities. The purpose of this review is to provide an update on the latest evidence for retinal involvement in migraine, derived from studies using spectral domain and swept source optical coherence tomography (OCT), including OCT angiography, with a particular emphasis on the relevance of this information for eyecare practitioners.
Should “Retro-ocular Pain, Photophobia and Visual Acuity Loss” Be Recognised as a Distinct Entity? The ROPPVAL Syndrome
Published in Neuro-Ophthalmology, 2021
Francesco Pellegrini, Erika Mandarà, Daniele Brocca
In accordance with Jefferis et al. we support the hypothesis of ROPPVAL syndrome being a subtype of migraine with its own specific clinical features, which must be differentiated from common migraine and the more rare and still debated retinal migraine.
