Traumatic Optic Neuropathy [TON] - A Review
نویسنده
چکیده
It is generally presumed that penetrating injuries of the orbit are associated with direct optic nerve injury. The incidence of TON after craniofacial trauma has been reported to be 0.5-1.5 % in older series. However, recent surveys report a higher figure; 2-5 % . This increased incidence may represent the diagnosis of subtle forms of TON closer to the time of injury. These types of cases appear to represent a smaller percentage of cases in the earlier studies on TON and may have been missed at that time. Males represent the majority afflicted with TON, comprising 60-95 % of cases . In one series focused on children, 40 % of the cases were female .
