Posterior lenticonus with persistent fetal vasculature

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Genetics

Background:

• Persistent fetal vasculature (PFV) is a congenital anomaly resulting from the failure of regression of the primary hyaloid vascular system.
• Posterior lenticonus is a rare condition characterized by a conical protrusion of the posterior lens surface, often associated with genetic syndromes.

Observation:

• A 10-year-old female presented with bilateral central cataracts and posterior lenticonus.
• Intraoperative findings revealed bilateral persistent fetal vasculature (PFV).

Findings:

• This case represents the first reported instance of the association between bilateral posterior lenticonus and PFV.
• The co-occurrence supports the hypothesis that PFV may be involved in the pathogenesis of posterior lenticonus.

Implications:

• This association may indicate an underlying genetic link or a shared developmental pathway between PFV and posterior lenticonus.
• Further research is warranted to elucidate the precise mechanism by which PFV influences lenticonus development.
• Understanding this relationship could lead to improved diagnostic and therapeutic strategies for pediatric lens abnormalities.
