Familial retinal arterial tortuosity (fRAT) is characterized by marked tortuosity of second- and third-order retinal arteries with normal first-order arteries and venous system. Patients have variable transient vision loss owing to retinal hemorrhages after minor stress or trauma. Prognosis is usually excellent. Whether there is systemic involvement is controversial. We report 3 cases of fRAT associated with a high degree of tortuosity of capillaries at nailfold capillaroscopy as an indication of systemic vascular pathology.
Report of Cases
Case 1. A woman was first seen at age 19 years because of blurred vision after a minor car accident. Best-corrected visual acuity (BCVA) was 0.9 OD and 0.8 OS. Ophthalmologic examination revealed marked tortuosity of second- and third-order retinal arteries and multiple intraretinal and preretinal hemorrhages in both eyes (Figure 1A). The patient was observed. Four . . . [Full Text of this Article]
