"Blow-in" fracture of the orbit with partial visual loss and choroidal folds.
Choroidal fold formation caused by "blow-in" fracture of the orbit is described. Rapid and almost complete recovery of vision followed removal of the bone fragments compressing the globe. The findings in this case support the conclusions of recent animal experiments on the pathogenesis of choroidal folds. Congestion of the choroid and adhesions to Bruch's membrane are probably prerequisites for folds to form, and folds are aligned perpendicular to a force applied to the eye.
