Electron microscopical studies on the resorption of vitreous hemorrhages.
An electron microscopical study of vitreous structure in 14 eyes suffering from different types and durations of vitreous hemorrhages submitted to vitrectomy showed the typical stages of disintegration of erythrocytes. Neither the type (retrovitreal, intravitreal or combined retro- and intravitreal) nor the duration of the vitreous hemorrhages influenced the histological picture significantly. In cases of shrinkage of the vitreous body the collagen fibrillar meshwork showed normal periodicity of 640 A, partly split and irregular.
