Uveitis is a major cause of visual impairment. Most uveitis cases have autoimmune etiology. Pediatric autoimmune uveitis may be associated with systemic diseases such as juvenile idiopathic arthritis or may arise as an isolated disorder. It may be accompanied by retinal vasculitis due to retinal microcirculation involvement. Nailfold capillaroscopy, a digital microscope, is a non-invasive tool for systemic microcirculation evaluation. We aimed to evaluate systemic microcirculation abnormalities in pediatric autoimmune uveitis. Twenty-five patients with pediatric autoimmune uveitis and 21 healthy children underwent detailed capillaroscopic evaluation. We assessed capillary density/mm, capillary morphology, capillary dimensions, and the presence or absence of microhemorrhages and avascular areas. The mean age of the study and control groups was 11.24 ± 3.03 and 9.9 ± 4.17 years, respectively. Most …
