“…Frequent cause of optic nerve injury are road traffic accidents [4][5][6][7][8]. However, in children a fall from a height is responsible in over half of the patients [1], In the present study 25 children had a history of a fall and 20 children were involved in road traffic accidents.…”

“…Traumatic optic neuropathy is a rare condition and is reported in less than 5% of all head injury patients [3][4][5]. There are only a few large series published in the world literature [2,6,7], Apart from our paper [1] no other paper has been published analyzing optic nerve injury in children.…”

“…However, an immediate type of visual deterioration [1][2][3][4][5]9] is more frequent. Logically, immediate type of visual loss implies the possibility of avulsion or transection of the optic nerve.…”

“…5], Sometimes head injury can be trivial and may not even cause loss of consciousness [3,4,7], Maha patra and Bhatia [4] reported loss of consciousness in 87% cases with unilateral optic nerve injury. In the present study in 20% children there was no loss of con sciousness.…”

“…Surprisingly, apart from this study no other paper has been published dealing with pediatric optic nerve injury [ 1 ]. Optic nerve injury is an uncommon condition, and involves less than 5% of all head injury patients [2][3][4][5]. The pathophysiology of optic nerve involvement is not well understood and the indications for optic nerve de compression not clear.…”

Fifty children with indirect optic nerve injury were prospectively studied over an 8-year period. They constituted 20% of all patients with optic nerve injury managed on a slightly different protocol. Half of these children were injured due to fall from a height, followed by road traffic accidents in 40% of the cases. Forty-three children had unilateral and 7 children had bilateral visual impairment. Five children had definite history of delayed-onset visual involvement, which ranged from 12 to 72 h following injury. Fifty percent of these children had fractured skulls and 14% had optic canal fracture. Visual evoked potentials were performed in 43 patients of which wave formation was normal in 7 and abnormal in 14 patients. The remaining 22 patients had no wave formation. All the patients were managed conservatively and received corticosteroids for a period of 3 weeks. In 7 children an optic nerve decompression was performed between 4 and 6 weeks following injury. Spontaneous visual improvement was observed in 20 (40%) children. In all the patients onset of visual recovery was noticed within 3 weeks. Of the 7 children who had optic nerve decompression, 4 had minimal spontaneous recovery and their vision remained static. All these 4 children benefited by surgery and the vision improved further following the decompression. Three children had no perception of light prior to surgery and none of these patients showed visual improvement following surgery. The present study brings out the clinical profile of children with optic nerve injury and the indications of surgery in these patients.
