Review Meta Analysis
The Diagnostic Accuracy of Bedside Ocular Ultrasonography for the Diagnosis of Retinal Detachment: A Systematic Review and Meta-analysis.
The diagnostic accuracy of emergency department (ED) ocular ultrasonography may be sufficient for diagnosing retinal detachment. We systematically reviewed the literature to determine the diagnostic accuracy of ED ocular ultrasonography for the diagnosis of retinal detachment. This review conformed to the recommendations from the Meta-analysis of Observational Studies in Epidemiology statement. ⋯ The results of the bedside ocular ultrasonography were compared with the reference standard of an ophthalmologic evaluation; one trial also included orbital computed tomography findings suggestive of retinal detachment. Bedside ocular ultrasonography has a high degree of accuracy in identifying retinal detachment, according to 3 small prospective investigations. Larger prospective validation of these findings would be valuable.

Federal regulations permitting an exception from informed consent for research in emergency settings require community consultation before study approval. Rates of acceptance of exception from informed consent in community consultation are often reported, but predictors of acceptance are not well understood, and investigators and institutional review boards struggle to interpret and use acceptance data. ⋯ Personal acceptance clustered between 64% and 80%. This range may be informative for institutional review boards and investigators evaluating community consultation results. However, numerous factors affect acceptance, and there is a need for considerable caution against overreliance on acceptance data.
