ABSTRACT
Objective: To provide the demographic data, risk factors, and visual prognosis of patients from a Saudi population diagnosed with non-arteritic anterior ischemic optic neuropathy (NAION). Materials and Methods: A retrospective observational case series of 120 patients (146 eyes) with NAION from the King Khaled Eye Specialist Hospital or King Abdulaziz University Hospital from 1998 to 2015. Patients with other retinal pathology or glaucoma were excluded from the study. Additionally, a subgroup analysis was performed to compare the long-term assessment between diabetic and non-diabetic patients and its effects on NAION. Results: The mean duration of follow-up was 1.7 ± 2.4 years. The mean age of the study population was 55.0 ± 10.1 years. NAION was present in the fellow eye of 26 patients, and the median time for involvement was less than 1 year from the presentation. There was no significant difference in the best-corrected visual acuity between diabetics and non-diabetics at presentation or last visit (P = 0.868, P = 0.599, respectively). Conclusions: The majority of patients with NAION also had coexisting diabetes mellitus. Diabetes mellitus had no significant effect on NAION during the presentation, follow-up, and last visit.
ABSTRACT
BACKGROUND AND OBJECTIVES: Seating position in motor vehicle collisions (MVC) plays a major role in determining the injury pattern in mainly restrained children. However, compliance with child seating and restraint laws is still suboptimal. The role of seating position in predicting injury patterns among unrestrained children has not been previously studied. DESIGN AND SETTING: Retrospective review based on the trauma registry of a level I trauma center in Riyadh, Saudi Arabia. Data collection was restricted to unrestrained children involved in MVC. PATIENTS AND METHODS: Between July 2001 and March 2010, 274 records were identified. Detailed information about the collision, child seating position and the use of restraints was cross-verified using parental phone interviews. RESULTS: Of the 274 identified records, cross-verification was possible for 89 (32.4%) unrestrained children, 64 boys and 25 girls, with a mean (SD) age of 83 (40) months. Of these children, 41 (46.1%) were front seated (FS), and 48 (53.9%) were back seated (BS). There were higher rates of rollover (52.1% vs 24.4%, P=.02), ejection (41.7% vs 22%, P=.05), and occupant death ratio (14.8 vs 4, P=.04) among BS children. However, the two groups did not differ in pediatric trauma scores, Glascow coma scale score, or age distribution. FS children were more likely to present with isolated head, neck or facial injuries (HNFI) (51.2% vs 25%, P=.01), whereas BS children were more likely to suffer long bone or pelvic fractures (LPF) (60.4% vs 36.6%, P=.025). CONCLUSION: Injury pattern can vary according to seating position among unrestrained children presenting at trauma centers after MVC. While FS children are more likely to present with HNFI, BS children more often sustain LPF. BS children had similar trauma severity compared with FS children despite the higher-impact nature of their MVCs. While highlighting the value of proper restraints use and seating position, these results can be valuable in the initial assessment of traumatized children involved in MVC.
