“…5,6 In this family, the eye phenotype remained constant throughout life but other features changed with age. We consider ischemic causes (which have previously been reported in light-induced amaurosis) unlikely because ERDB remains benign for many decades, is stereotyped, and is systematically and rapidly reversible.…”

The authors report a family affected by multiple daily episodes of transient visual loss, elicited repetitive daily blindness (ERDB); the onset was early in life, and the disease followed a benign course. ERDB is associated with childhood epilepsy and familial hemiplegic migraine, apparently segregating as a monogenic, autosomal dominant condition with variable expression. Genetic linkage to CACNA1A was excluded.

“…CAS is a prominent risk factor for ophthalmic ischemic complications such as amaurosis fugax, central retinal artery occlusion, and ocular ischemic syndrome since the ophthalmic artery is a branch of internal carotid artery (ICA) and the central retinal artery arises from the ophthalmic artery. Transient monocular visual loss that can be induced by exercise, position, and bright light amaurosis is another typical clinical phenomenon associated with CAS [ 2 ]. An intramural hematoma may cause stenosis and eventual trombus formation leading to carotid dissection as a severe complication.…”

Purpose: We aimed to analyze retinal microvascular parameters, measured by optical coherence tomography angiography in patients with internal carotid artery stenosis compared to healthy individuals. Materials and Methods: A total of 41 eyes from 30 patients who had varying degrees of carotid stenosis, and 42 eyes from 42 healthy controls, were enrolled in this study. Depending on the degree of stenosis evaluated by Doppler ultrasonographic imaging, the patient group was further subclassified into mild, moderate, and severe carotid artery stenosis. Superficial and deep capillary plexus vessel densities, radial peripapillary capillary vessel density, foveal avascular zone, and flow densities in the choriocapillaris and outer retina were evaluated by optical coherence tomography angiography. Results: The superficial and deep capillary plexus vessel densities were significantly reduced among the groups, only sparing the foveal region. The mean superficial plexus vessel density was 45.67 ± 4.65 and 50.09 ± 4.05 for the patient and control group, respectively (p = 0.000). The mean deep capillary plexus density was 46.33% ± 7.31% and 53.27% ± 6.31% for the patient and control group, respectively (p = 0.000). The mean superficial and deep capillary vessel densities in the foveal region did not show any statistical difference between the patient and control groups (p = 0.333 for the superficial and p = 0.195 for the deep plexus vessel density). Radial peripapillary capillary vessel density was decreased in the patient group (p = 0.004). The foveal avascular zone area was wider in the patient group but this difference did not show a significant difference (p = 0.385). Conclusions: Retinal microvascular changes are a prominent outcome of internal carotid disease, and even mild stenosis can lead to alterations in the retinal microvascular bed which could be detected by OCTA. By early detection of microvascular changes in the retina in this patient group, we might speculate the overall vascular condition.
