Purpose: To compare 4 optical coherence tomography-angiography (OCT-A) devices for foveal avascular zone (FAZ) measurements in healthy subjects.
Methods: The central retinas of 24 eyes of 12 healthy subjects were scanned with 4 different OCT-A devices (Optovue RTVue-XR, Zeiss Cirrus 5000-HD-OCT, a prototype Spectralis OCT2, Heidelberg Engineering, and Topcon DRI-OCT Triton Swept-source OCT). For the Topcon, Zeiss, and Optovue devices, 3-mm and 6-mm scans were performed.
Background: There are diverse causes of cicatricial alopecia characterized by lack of follicular ostia and irreversible loss of hair. While clinical differentiation between the causes may be difficult, particularly with regard to lichen planus (LP), lupus erythematosus (LE) and pseudopelade of Brocq (PB), it has been suggested that both histopathologic examination and direct immunofluorescence studies (DIF) are necessary for an accurate diagnosis.
Objective: The aim of this study was to evaluate the diagnostic value of DIF studies in addition to histopathology in patients with cicatricial alopecia as a clinical feature.
