[The value of studying the ocular conjunctiva in case-finding in prediabetic states].
Capillaroscopy, the only method available for the study of the microcirculation, without modifying its hydraulics, often provides a wealth of information in certain systemic diseases in which the microcirculatory involvement precedes clinical manifestations and of course, macrovascular complications. The prospective study of a healthy population is particularly demonstrative and the authors proposed scores on which diabetic microangiopathy could be suspected. The latter was confirmed by detailed laboratory investigations on one hand, and by the course of the disease on the other. For this reason, any subject at risk of diabetes should undergo at least one annual capillaroscopic examination of the ocular conjunctiva or if not, of the peri-ungual region. Furthermore, the study of microvessels in subjects with controlled and treated disease showed a regression of the anomalies which depended on proper control of diabetes, and this particularly nontraumatic test procedure which can be repeated and provides a wealth of information, can give a good reflection of proper therapeutic control, especially if it is performed by a trained and experienced investigator.
