Aims:
To review the ocular manifestations of crush head injuries in children.
Methods:
Retrospective clinical and pathological reviews. Group 1: A total of 16 children admitted with crush head injuries from television tip over. Group 2: Nine autopsy findings in crush head injury.
Results:
Group 1: A total of 11 children had fundus examination: three by neurosurgeons, eight by ophthalmologists. Scattered posterior pole preretinal and blot haemorrhages extending to mid equator region observed in one child. No evidence of traumatic retinoschisis or retinal folds in any patient. Group 2: All with multiple skull fractures and six with subdural haemorrhage. Posterior pole retinal haemorrhages in four children, extending to the ora serrata in one after motor vehicle accident. No child had retinal folds. Subinternal limiting membrane haemorrhages in three children. Optic nerve sheath haemorrhage in three children.
Conclusions:
Intraretinal and preretinal haemorrhages, predominantly in the posterior pole, can occur in crush injury to the paediatric head. Haemorrhage under the internal limiting membrane or extending to the ora serrata were only seen in situations where crush injury was part of a fatal trauma scenario related to motor vehicles. Retinal folds and the typical macular retinoschisis associated with abusive head injury were not observed.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
