Cutaneous cystic lesions (n = 35) were examined with optical coherence tomography. Cysts were visible as a hyporeflective roundish area with a clear margin; in some cases, the epidermis was thinned. Epidermal cysts, trichilemmal cysts, and hidrocystomas had a linear margin representing the epithelium of the cyst, whereas mucoid pseudocysts showed no linear margin. Trichilemmal and epidermal cysts presented with hyperreflective content that corresponds to keratin. By visualizing the margin and the content of the cyst, it was possible to differentiate between different types of cysts.

Purpose: This study investigates the association between visual function and retinal vasculature metrics, particularly perfusion capacity (PC), in eyes with idiopathic epiretinal membrane (iERM), using optical coherence tomography angiography (OCTA).
Methods: This retrospective study includes 30 eyes from 30 iERM patients who had surgery, with a three-month follow-up period. In addition, 28 eyes from 28 healthy individuals served as a control group.

Purpose: The purpose of this study was to develop ground-truth histology about contributors to variable fundus autofluorescence (FAF) signal and thus inform patient selection for treating geographic atrophy (GA) in age-related macular degeneration (AMD).
Methods: One woman with bilateral multifocal GA, foveal sparing, and thick choroids underwent 535 to 580 nm excitation FAF in 6 clinic visits (11 to 6 years before death). The left eye was preserved 5 hours after death.
Anterior segment optical coherence tomography (AS-OCT) assisted analysis of characteristics of graft dehiscence after Descemet membrane endothelial keratoplasty (DMEK) for failed penetrating keratoplasty.

Department of Ophthalmology, Faculty of Medicine, University of Cologne, Cologne, Germany.
Purpose: To analyse anterior segment optical coherence tomography (AS-OCT) parameters of graft dehiscence after Descemet membrane endothelial keratoplasty (DMEK) for graft failure post penetrating keratoplasty (PK).
Methods: Retrospective evaluation of AS-OCT images of 142 dehiscences post-DMEK in 75 eyes. Dehiscences' size, depth, location, correlation with graft-host interface (GHI) override and step at GHI were assessed.

Spontaneous neural activity coherently relays information across the brain. Several efforts have been made to understand how spontaneous neural activity evolves at the macro-scale level as measured by resting-state functional magnetic resonance imaging (rsfMRI). Previous studies observe the global patterns and flow of information in rsfMRI using methods such as sliding window or temporal lags.
