Galvanic stimulation of the tongue as a prognostic index in Bell's palsy.

Fluoresceinretinography-Skovborg and Lauitzen Mast a single blood dot by ordinary ophthalmoscopy of these patients.By microscopy of the retina it is also rather unusual to find microaneurysms.These facts combined with the observation that fluorescent dots disappear quickly during treatment of the hypertension (Hodge and Dollery, 1964) indicate that the fluorescent dots are due to exudates which are not ophthalmoscopically visible. SummarySome of the results from fluoresceinretinography of diabetic patients are demonstrated, and the interpretation of some of the observations is discussed.It is concluded that most of the small fluorescent dots which appear in diabetics and hyper- tensive patients can be interpreted as small exudates rather than microaneurysms.
