[Correlation between form and progression of diabetic preretinitis (author's transl)]

Ninety-three patients with typical symptoms of diabetic preretinitis were kept under observation for three to five years (on average 3.9 years), and examined by fluorescein angiography at least once a year. The progress of the various individual symptoms, such as capillary occlusions, pigment extravasation from small vessels, microaneurysms and AV shunts was statistically significant in patients suffering from a predominantly occlusive form of diabetic preretinitis. Hence, more rapid progression of changes must be expected in such patients thn in those suffering from exudative forms.
