Key result
Ocular pneumoplethysmography predicts pressure-significant internal carotid lesions with ~93% accuracy, outperforming ophthalmodynamometry.
Why the study?
Does ocular pneumoplethysmography improve diagnostic accuracy compared to ophthalmodynamometry for predicting pressure-significant lesions of the internal carotid system in patients having cerebral angiography?
Observational (n=119)
Does ocular pneumoplethysmography improve diagnostic accuracy compared to ophthalmodynamometry for predicting pressure-significant lesions of the internal carotid system in patients having cerebral angiography?
Absolute Event Rate: 92.5% vs 76%
Ocular pneumoplethysmography is significantly more accurate than ophthalmodynamometry for detecting pressure-significant lesions of the internal carotid system.
No takes yet. Share an insight, caveat, or question.
May support ocular pneumoplethysmography for carotid assessment; leaves open prospective validation before practice change.
Wiebers et al. (1982) conducted an observational in Carotid Occlusive Disease (n=119). Ocular pneumoplethysmography vs. Ophthalmodynamometry was evaluated on Overall accuracy for predicting pressure-significant lesions of the internal carotid system. Ocular pneumoplethysmography had significantly higher overall accuracy (92.5%) than ophthalmodynamometry (76%) for predicting pressure-significant lesions of the internal carotid system.
