A clinical case of congenital nasoorbital craniocerebral hernia

Congenital craniocerebral hernias are malformations in which the brain and the meninges protrude through congenital defects of the skull. Treatment of this pathology is only surgical and should be carried out as early as possible to prevent changes in the facial skull and pathology of the optic nerve. The patients require constant observation by neurologist and ophthalmologist. The article presents a clinical case of left-sided congenital nasoorbital craniocerebral hernia. Due to the untimely surgery, there was a progressive decrease of visual acuity due to partial optic nerve atrophy and formation of complex hyperopic astigmatism.
