Case Report:
A 5-year-old male presented with bilateral poor vision, esotropia and a previous diagnosis of cataract since he was 1 year old. The physical examination revealed bilateral posterior paracentric capsule opacification, vitreous cavity with a permeable pulsatile blood filled hyaloid artery in both eyes. He was kept under observation.
Discussion:
Persistent hyaloid artery is an uncommon faulty primary vitreous regression, often unilateral (although it may be bilateral) and sporadic, associated with microphthalmos. It may be complicated with glaucoma and phthisis bulbi. Vitrectomy plus lensectomy or simple observation are the accepted treatment options.
