Type 1 diabetes mellitus (T1DM) is associated with an increased lifetime risk of developing diabetic retinopathy, a leading cause of visual impairment among working-age adults worldwide. Retinal assessment plays a pivotal role in the management of patients with T1DM, as the retina provides a unique, non-invasive window into the body's microvascular circulation. Early detection of retinal abnormalities is essential because structural and microvascular changes may develop years before the onset of vision-threatening diabetic retinopathy or visual symptoms. Contemporary retinal imaging techniques, enable the quantitative evaluation of retinal microvasculature allowing the identification of subclinical retinal damage.
Study Type
OBSERVATIONAL
Enrollment
100
A non-invasive retinal imaging technique that provides high-resolution visualization and quantitative assessment of the retinal and choroidal microvasculature, including vessel density and the foveal avascular zone, without the use of intravenous dye.
2nd Department of Ophthalmology, Attikon University Hospital, National and Kapodistrian University of Athens
Athens, Greece
Quantitative assessment of retinal vessel density measured by optical coherence tomography angiography (OCTA).
Time frame: Vessel density will be assessed at baseline using OCTA. This is a cross-sectional study; no follow-up assessments will be performed. Participants will be evaluated at a single study visit and classified according to the stage of diabetic retinopathy.
