[Evolutive posterior forms of persistent fetal vasculature bilateral at Gao regional hospital]

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Developmental Biology

Background:

• Persistence of fetal vasculature (PFV) is a congenital anomaly resulting from the incomplete regression of the embryonic hyaloid vascular system.
• This condition can lead to various ocular abnormalities, impacting visual development in infants and children.

Observation:

• A 2-year-old child presented with bilateral leukocoria (white pupillary reflex) and exotropia (outward turning of the eyes).
• Ocular examination revealed fibrovascular retinal bands extending from the optic disc to the ora serrata in both eyes.
• The right eye showed total retinal detachment, while the left eye exhibited partial inferior and anterior temporal retinal detachment, along with peripheral pigmentary changes.

Findings:

• The case highlights the posterior form of bilateral PFV, characterized by significant fibrovascular proliferation and retinal detachment.
• Bilateral leukocoria and strabismus were the primary clinical manifestations in this pediatric patient.

Implications:

• Prompt diagnosis and management of PFV are essential to prevent irreversible vision loss and amblyopia.
• This case underscores the importance of thorough funduscopic examination in children presenting with leukocoria for timely intervention.
