Transient-like function and associated retinal capillary anomalies. Analysis of a patient with early retinopathy secondary to juvenile-onset diabetes mellitus.
A juvenile diabetes patient exhibiting limited early microvascular changes in the retina has been studied intensively. Like some others showing early signs of diabetic retinopathy, he manifests anomalies in a retinally based transient-like function. At all points tested in this case the sustained-like function was found to be normal. Because his functional and anatomic anomalies are stable and cover a reasonably extensive area of visual field and retina, it is possible to attempt correlative studies with other visual response functions. The transient-like function proves to be a more sensitive indicator of anomaly in this patient than static perimetry or critical flicker frequency.
