Investigation of Ultrawidefield OCTA to Assess the Effects of Posterior Precorical Vitreous Pocket on Retinal and Choroidal Structure and Blood Flow
Clinical Report: Investigation of Ultrawidefield OCTA and PPVP Effects
Overview
This study investigates the association between the posterior precortical vitreous pocket (PPVP) and retinal parameters in healthy individuals. Findings indicate that PPVP presence correlates with increased retinal thickness, volume, and blood flow, suggesting its potential role in retinal health and disease.
Background
The posterior precortical vitreous pocket (PPVP) is a normal anatomical structure at the vitreoretinal interface, which has been linked to various macular diseases. Understanding its influence on retinal morphology and blood flow is crucial for elucidating its role in ocular health and potential pathologies. This study aims to clarify the relationship between PPVP and retinal parameters in a healthy cohort.

Key Findings
PPVP was detected in 72.3% of healthy subjects.
PPVP-positive individuals exhibited greater retinal thickness in the superior and nasal inner macula.
Increased volume was observed in the superior inner macula among PPVP-positive subjects.
Vessel density was significantly higher in both superficial and deep nasal retina in the PPVP-positive group.
These findings suggest a biomechanical or microcirculatory influence of PPVP on the retina.
Clinical Implications
Discuss specific retinal disorders where PPVP presence may be particularly relevant.
Conclusion
This study highlights the significant association between PPVP and retinal structural parameters, suggesting its importance in the physiological understanding of the vitreoretinal interface. Further research may elucidate its role in retinal pathologies.
US claims data showed rising prevalence of diabetic retinal disease in type 1 and type 2 diabetes, while incidence declined in type 1 diabetes and moved closer to type 2 rates by 2022.
