Analysis of Characteristics and Trends in Treatment Response of Hidradenitis Suppurativa Patients: A Southern US Cohort Study.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that has a substantial impact on patients' quality of life. As the exact pathogenesis remains unclear, treatment is complex and not yet standardized.

Objectives: The aim of this study was to describe patient characteristics and to broadly examine trends in treatment response of various therapeutic strategies in patients with HS in a single academic referral center in the southern USA.

Effect of motion artifacts and scan circle displacements on Cirrus HD-OCT retinal nerve fiber layer thickness measurements.

Purpose: To evaluate the effect of scan circle displacements on retinal nerve fiber layer thickness (RNFLT) measurements in Cirrus HD-OCT scans with motion artifacts affecting the optic disc.

Methods: In this cross-sectional study, 70 scans from 18 healthy eyes and 100 scans from 26 glaucomatous eyes were divided into 85 pairs, each composed by a scan with one motion artifact affecting the optic disc, and a scan from the same eye without motion artifacts. En face images underwent automated realignment, and horizontal/vertical scan circle displacements were determined.
