Article Abstract
Purpose: This study aimed to elucidate the distribution and morphological features of choroidal vortex veins in pachychoroid disease (PCD).
Design: Retrospective observational study.
Subjects: Patients with PCD included from January 2022 to June 2023.
Methods: We conducted a retrospective cross-sectional analysis using wide-field indocyanine green angiography (WF-ICGA) to assess choroidal vortex veins in PCD patients, categorizing them based on location (equatorial/posterior) and morphology (absent, incomplete, complete, complete with ampulla).
Main Outcome Measures: The incidence of different location and morphology of vortex veins in PCD.
Results: A total of 190 eyes from 99 PCD patients were examined. Notably, only 8.9 % (17/190) of eyes had posterior vortex veins. We identified 1620 vortex veins, predominantly equatorial (99 %, 1603/1620). Morphologically, the most common type was incomplete (61.9 %), followed by complete (19.5 %), absent (11.1 %), and complete with ampulla (7.5 %). The distribution of these veins varied, with the inferotemporal quadrant showing the highest prevalence at 26.9 %, followed by the superonasal (26.1 %), superotemporal (24.3 %), and inferonasal (22.7 %) quadrants. The median number of vortex veins per eye was 8, with a range from 5 to 15.
Conclusions: This study highlights that posterior vortex veins are less frequent in PCD eyes, with incomplete veins being the most prevalent. These findings provide important clinical evidence for understanding the distribution and morphologic characteristics of choroidal vortex veins in PCD, contributing to our knowledge of the pathophysiological mechanisms underlying this condition.

Purpose: To investigate the spatial relationship between choroidal vortex veins (VVs), choroidal watershed zones (CWZs), and polypoidal lesion distribution in different subtypes of polypoidal choroidal vasculopathy (PCV) categorized by choroidal vascular hyperpermeability (CVH) status.
Methods: This retrospective study analyzed 58 treatment-naïve PCV eyes using widefield imaging to map dominant VVs, CWZs, and lesion locations. Eyes were stratified into CVH (n = 32) and non-CVH (n = 26) groups.

Hyperperfusion injury is a major contributor to small-for-size syndrome (SFSS) following liver transplantation, particularly in left-liver transplantation (LLT). Given donor preservation constraints, "left-at-right" liver transplantation (LAR-LT) has emerged as a potential strategy to mitigate this complication. This study employed computational fluid dynamics (CFD) to investigate the mechanical mechanisms underlying SFSS in five patients who underwent LLT at Beijing Friendship Hospital.

Scleral buckling (SB) has been a cornerstone in the surgical management of rhegmatogenous retinal detachment for decades, achieving success rates above 85 %; however, its impact on choroidal architecture and hemodynamics has been less thoroughly explored until recent advancements in ocular imaging techniques. We synthesize current evidence on the effects of SB surgery on choroidal structure and circulation, examining its implications for postoperative complications and exploring a potential link with the newly described spectrum of acquired venous overload choroidopathy (AVOC). Various imaging modalities including indocyanine green angiography, optical coherence tomography (OCT), and OCT angiography have demonstrated that SB induces both transient and sometimes persistent alterations in choroidal thickness, blood flow patterns, and vascular morphology, with encircling buckles showing more pronounced and enduring effects than segmental approaches.

Introduction: Novel ocular findings have been identified in spaceflight. We discuss their potential association with Spaceflight Associated Neuro-ocular Syndrome (SANS) and integrate them in a framework that may help explain the pathophysiology.
Methods: We reviewed literature using the Medline/PubMed database starting in October 2020.
