Does high-resolution optical coherence tomography correlate in ischemic radiation retinopathy?
This report suggests that the radiation-induced damage was confined to the inner layers of the retina. However, secondary outer retinal layer changes may also occur, as suggested by functional derangements.
Young and elderly symptomatic subjects are more likely to have methacholine AHR. None of the clinical variables we studied has significant predictive value for methacholine AHR across the age groups, so these variables are poor selection criteria for methacholine bronchoprovocation testing of symptomatic subjects. Given the high prevalence of AHR among these subjects, bronchoprovocation should be considered with all individuals who have respiratory symptoms of wheezing, cough, shortness of breath, or chest tightness.
