Lens-sparing vitreous surgery for infantile amblyogenic vitreous hemorrhage.

Abstract

To report on a series of infants with amblyogenic vitreous and/or subinternal limiting membrane hemorrhage managed by lens-sparing vitrectomy. Retrospective case series studying retinal attachment status and visual acuity. Eleven eyes sustained vitreous hemorrhage as a consequence of shaken baby syndrome, 1 due to hyaloidal canal hemorrhage extending into the vitreous, 1 due to Terson syndrome, 1 due to birth trauma, and 2 due to a presumed coagulation disorder. Age of the patients at the time of surgery ranged from 2 to 23 months (age adjusted for prematurity). Follow-up ranged from 7 to 81 months (mean, 28 months). Ten eyes had visual improvement. Two infants with shaken baby syndrome had bilateral nonrecordable flash visual evoked potential before surgery; one eye of one infant had a better than expected visual outcome after surgery. One eye sustained a retinal tear without detachment. One eye in an infant with severe shaken baby syndrome and traumatic retinopathy developed a total rhegmatogenous retinal detachment with proliferative vitreoretinopathy. Infantile amblyogenic vitreous hemorrhage may be effectively managed by lens-sparing vitreous surgery. Visual outcome of shaken baby syndrome may be limited as a consequence of structural damage to the retina, optic nerve, or posterior visual pathways.
