Refractive error changes in children with intermittent exotropia under overminus lens therapy.

Purpose: Intermittent exotropia may be decreased by stimulation of accommodative convergence. Once excessive accommodation has been related to myopia, our objective was to evaluate refractive errors changes in children under overcorrecting minus lens therapy.

Methods: A retrospective chart review of 21 children with intermittent exotropia was performed.

Orbital abscess secondary to acute dacryocystitis: case report.

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.
