Vertical folds of central retinal and choroid in sudden ocular decompression.

Sudden and limited decompression of an eye due to corneal rupture has four days later allowed for the histopathological demonstration of an interesting combination of a vertical retinal fold, cystoid macular edema, degeneration of foveal cones, a vertical choroidal fold with loss of pigment epithelium and papilledema. The rather bizarre changes in this case may be helpful for the understanding of the much more subtle histopathological findings in typical cystoid macular edema.
