Damage to the eye and optic nerve in seriously traumatized patients with concomitant head injury: analysis of 84,627 cases from the TraumaRegister DGU® between 2002 and 2015

Abstract

Background: To determine the prevalence and characteristics of prechiasmatic visual system injuries (VSI) among seriously injured patients with concomitant head trauma in Europe by means of a multinational trauma registry. Methods: The TraumaRegister DGU® was searched for patients suffering from serious trauma with a Maximum Abbreviated Injury Scale (AIS) ≥ 3 between 2002 and 2015 in Europe. After excluding cases without significant head injury defined by an AIS ≥ 2, groups were built regarding the existence of a concomitant damage to the prechiasmatic optic system comprising globe and optic nerve. Group comparisons were performed with respect to demographic, etiological, clinical and outcome characteristics. Results: 2.2% (1901/84,627) of seriously injured patients with concomitant head trauma presented with additional VSI. These subjects tended to be younger (mean age 44.7 versus 50.9 years) and were more likely of male gender (74.8% versus 70.0%) compared to their counterparts without VSI. The most frequent trauma etiologies were car accidents in VSI patients (28.5%) and falls in the control group (43.2%). VSI cases were prone to additional soft tissue trauma of the head, skull and orbit fractures as well as pneumocephalus. Primary treatment duration was significantly longer in the VSI cohort (mean 23.3 versus 20.5 days) along with higher treatment costs and a larger proportion of patients with moderate or severe impairment at hospital discharge despite there being a similar average injury severity at admission in both groups. Conclusions: A substantial proportion of patients with head injury suffers from additional VSI. The correlation between VSI and prolonged hospitalization, increased direct treatment expenditures, and having a higher probability of posttraumatic impairment demonstrates the substantial socioeconomic relevance of these types of injuries.

Which Individuals with Positive Family History of Gastric Can-cer Urgently Need Intensive Screening and Eradication of Heli-cobacter Pylori? A Systematic Review and Meta-Analysis

“…According to the quality assessment of papers, 15 studies ( 24 – 27 , 29 , 30 – 35 , 39 , 45 ,, 48 , 51 ) were considered as “high quality”; 10 studies ( 23 , 28 , 36 – 38 , 40 – 43 , 52 ) were assigned as “fair to good quality”, and 5 studies ( 44 , 46 , 47 , 49 , 50 ) were regarded as low quality.…”

“…Data quality control was performed by inspectors, researchers, registry administrators, data management experts, and secretaries. Most registries evaluated also used terminologies and International Classification of Diseases System (Ocular Trauma Score, Birmingham Eye Trauma Terminology) to name, define and classify eye injuries ( 24 – 27 , 31 , 32 , 34 , 36 , 39 , 43 , 44 , 49 , 50 ) while only four registries have used the International Classification of Diseases Ninth Revision (ICD-9) coding systems. The International Classification of Diseases (ICD-10)) was used for classifying variety of injuries, medical interventions and treatments for eye injuries ( 30 , 31 , 33 , 37 , 40 ).…”
