Posterior Precortical Vitreous Pocket in Children

Area of Science:

• Ophthalmology
• Anatomy
• Medical Imaging

Background:

• The posterior precortical vitreous pocket (PPVP) is a relevant anatomical feature in the posterior eye.
• Understanding its development and characteristics is crucial for pediatric ophthalmology.

Purpose of the Study:

• To investigate the profile of the posterior precortical vitreous pocket (PPVP) in children using spectral-domain optical coherence tomography (OCT).
• To compare the PPVP profile in children with that of adults.

Main Methods:

• Retrospective comparative study using OCT imaging.
• Measurement of PPVP height at the fovea and horizontal diameter in children and adults.
• Calculation of the proportion of temporal length to the total horizontal diameter.

Main Results:

• No significant difference in PPVP height was found between children (355.3 ± 80.3 µm) and adults (367.8 ± 75.6 µm).
• The proportion of temporal PPVP diameter was significantly greater in adults (0.50 ± 0.03) than in children (0.45 ± 0.05).
• A positive association was observed between age and the proportion of temporal PPVP diameter in children.

Conclusions:

• The PPVP demonstrates progressive temporal extension throughout childhood.
• OCT is an effective tool for characterizing PPVP morphology in pediatric and adult populations.
