Corneal edema secondary to vitreocorneal contact

Aphakic eyes, some with edematous corneas, and others with corneas free of
edema, but all with formed vitreous humor in contact with the corneal
endothelium, were studied. Removal of vitreous humor from the anterior
chamber by closed vitrectomy resulted in substantial improvement in the
state of corneal hydration and, in some cases, in the elimination of
clinically notable corneal edema. Specular microscopy showed endothelial
abnormalities in the edematous corneas that were not present in corneas
with vitreous contact that remained free of edema. However, those
endothelial changes seen in edematous corneas before vitrectomy seemed to
persist after vitrectomy and corneal deturgescence. Thus, elimination of
vitreous contact may result in clinical reversal of corneal edema despite a
prolonged period of vitreous contact and in the face of seemingly
irreversible endothelial changes.
