Purpose: Bietti crystalline dystrophy (BCD) is a rare retinal dystrophy characterized by progressive visual impairment. This study aimed to evaluate changes in retinal and choroidal vessels and blood flow in BCD patients using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate potential parameters associated with visual function.
Methods: This cross-sectional study included 166 eyes from 86 clinically diagnosed BCD patients, classified into three disease stages based on Yuzawa's classification.

Purpose: When performed for clinically significant carotid artery stenosis (CAS), the long-term impact of carotid endarterectomy (CEA) on choroidal and choriocapillaris (CC) circulation was studied using swept-source OCT angiography.
Design: Prospective observational study.
Participants: Patients with clinically significant CAS undergoing unilateral CEA.
Axial length to corneal curvature radius ratio is negatively correlated with choroidal blood flow in myopic children.

Background: The pathophysiologic mechanisms underlying early-onset myopia remain unclear; in this study, we investigate the pathogenesis by examining the interrelationships between axial length to corneal curvature radius ratio ( ) and choroidal blood flow.
Methods: This cross-sectional study included 202 eyes from myopic children, categorized into 141 eyes with mild myopia, 47 eyes with moderate myopia, and 14 eyes with high myopia. Optical coherence tomography angiography (OCTA) was used to measure choroidal blood flow perfusion within a 6 mm × 6 mm area of the macular region, divided into nine subareas based on ETDRS partitioning: macular fovea, nasal side 1, superior 1, temporal side 1, inferior 1, nasal side 2, superior 2, temporal side 2, and inferior 2.

Shanghai Eye Diseases Prevention &Treatment Center/ Shanghai Eye Hospital, School of Medicine, Tongii University, Shanghai, China.
Objectives: To identify the role of fundus vascular arcades angle (VAA) in reflecting choroidal thickness (ChT) of highly myopic children and adolescents.
Methods: Participants aged 5 to 18 yrs with high myopia (spherical equivalent, SE ≤ -5.0 D) were enrolled and followed up for one year from the Shanghai Child and Adolescent Large-scale Eye Study.
