- Background : The risk of developing enduring post-traumatic stress reactions and mental health problems in the aftermath of disasters is substantial. However, there are inconsistencies regarding the contribution of physical injury as an independent risk factor for developing psychiatric morbidity after disasters. Aims : The aim was to assess whether physical injury was associated with post-traumatic stress reactions and general mental health after adjusting for perceived life-threat in the aftermath of the 2004 tsunami. Methods : A sample of 1501 highly exposed survivors from the 2004 Southeast Asia tsunami was selected from a cohort of Swedish survivors surveyed 14 and 36 months after the event. The impact of physical injury on post-traumatic stress and general mental health was assessed by regression models accounting for subjective life-threat. Results : Physical injury was associated with higher levels of post-traumatic stress reactions and poorer general mental health. These associations were observed at both 14 and 36 months after the disaster. Conclusions : Physical injury has a specific contribution to the association between traumatic experience and both post-traumatic stress reactions and general mental health in victims of the 2004 tsunami. The effect is stable over several years.

Journal article (peer-reviewed)abstract
- Visual field testing which the Computer fully automatic computerized perimeter (Heijl & Krakau 1975) employing a supra-liminal screening test procedure was used in a material of 1013 eyes with ocular hypertension in which earlier routine perimetry (kinetic and static) on the Goldmann perimeter had yielded a normal result. The automatic screening was repeated if positive, and manual control perimetry was used in order to confirm or reject identified field defects. This procedure revealed field defects that could be confirmed at both automatic and manual perimetry in 3.6% of the eyes. In the control group the incidence of field defects found at manual perimetry during the same time interval was calculated at 0.4%. Thus automatic screening revealed several times more field defects than manual routine perimetry. Eyes in which repeated automatic screening had indicated defects which manual control perimetry failed to confirm, showed a high percentage of field loss at later follow-up. The results are discussed, and the conclusion is drawn that automatic screening is clearly superior to manual routine perimetry used at present. The most practical solution in many eye departments would be to use a computerized perimeter for the visual field screening of glaucoma suspects.
