[Orbital firearm injuries]

Injuries caused by firearms are fortunately rare in the field of ophthalmology. The treatment of an affected patient is a special challenge both ophthalmologically and emotionally.

We report on seven consecutive cases of patients with an orbital gunshot injury who presented in a university hospital over a period of 11 years. The course of events leading to the injury with the weapon involved, the type of projectile, the injury pattern, cranial imaging, treatment and course were evaluated.

A total of seven cases of injuries caused by firearms could be documented and evaluated in the period 2007-2018. All seven patients were male. The average age was 44 ± 27.5 years. Of the injuries five were caused by a suicide attempt and two by an accident. Firearms were used except for one injury caused by a crossbow. There was a retained projectile in four of the cases, the bullet went through the body in two cases and one of the cases presented with a ricochet shot. The final visual acuity was unilateral amaurosis in 1 case and bilateral amaurosis in another case, 1/35 (measured at 1 m) in 1 case, while it varied between 0.2 and 0.7 in the other 4 cases. No patient died as a direct consequence of the firearm injury.

Injuries caused by firearms are relatively rare in Germany and mostly have a suicidal background. The pattern of the injury of the ocular structures is very variable. A reconstruction attempt is principally recommended. In the care of patients interdisciplinary cooperation between ophthalmologists and neurosurgeons, orofacial surgeons, ear nose and throat (ENT) surgeons and psychiatrists is necessary.
