Early Stage Retinal Abnormalities in Type 1 Diabetes, Screened With OCT Angiography.

NCT03496597 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 520

Last updated 2022-03-10

No results posted yet for this study

Summary

The improvement of imaging techniques in ophthalmology has made it possible to carry out a precise non-invasive study of the retinal microvascular network and to detect early abnormalities in retinal disorders. The presence of such early retinal abnormalities remains poorly known during type 1 diabetes and may be detected with OCT-angiography. Furthermore, the association with glycemic variability, likely to have deleterious effects on microvessels, has never been studied.

Conditions

  • Type 1 Diabetes Patients

Interventions

PROCEDURE

Retinal imaging assessment

* OCT-angiography * Automated measurement program: size of the avascular zone and perifoveolar vascular density of the superficial capillary plexus * Eye fundus photography: macular image * Measurement of the fractal dimension of the retinal foveolar retina from photographs of the fundus

PROCEDURE

blood glucose holter

for 40 subjects, implantation of a blood glucose holter monitor for 7 days
