title: Orbital abscess secondary to acute dacryocystitis: case report.
abstract: Acute dacryocystitis usually induces preseptal infection. In rare instances the infection that is confined to the lacrimal sac can extend to the orbital contents resulting in orbital cellulitis. We present a case of intraconal abscess secondary to acute dacryocystitis and review the literature of orbital cellulitis resulting from acute lacrimal sac infection.
