Purpose: To assess the relationship between foveal microcirculation and central retinal function in diabetic patients having both an enlarged foveal avascular zone (FAZ) and a preserved visual acuity (0.6 or better).
Methods: Twenty-five patients with diabetes type 1 or 2 with an enlarged FAZ (largest diameter > 650 microm) measured in fluorescein angiograms were examined with multifocal ERG (mfERG).
Purpose: To study the retinal function, using multifocal electroretinography (mfERG), in diabetic patients with mild and moderate retinopathy, and in diabetics without clinically apparent retinopathy.
Methods: Thirty-one patients with insulin dependent diabetes mellitus, eleven without any clinically apparent retinopathy, twelve with mild retinopathy and eight with moderate retinopathy, were studied. Ophthalmologic examination included testing of visual acuity, fundus inspection, fundus photography and mfERG.
