PURPOSE The aim of the study was to describe the prevalence of visual impairment and retinopathy and to investigate risk factors for retinopathy in persons with diabetes, screen-detected diabetes, impaired glucose tolerance and normal glucose tolerance in a subpopulation of the HUNT study. METHODS We used a sample (n = 163) from a population-based(More)
The purpose of this study was to evaluate the role of photopic full-field electroretinography (ERG) and retinal thickness measurements by spectral-domain optical coherence tomography (SD-OCT) in the assessment of disease severity in type 1 diabetic retinopathy. A population-based cohort of 151 patients with type 1 diabetes underwent a complete ophthalmic(More)
PURPOSE We have previously shown that photopic cone b-wave implicit time ≥ 35.0 ms in 30 Hz flicker electroretinography (ERG) predicts ocular neovascularization (NV) in central retinal vein occlusion (CRVO). Here, we evaluate the effects of early panretinal photocoagulation (PRP) in patients with ERG-verified ischaemic CRVO. METHODS Patients with CRVO,(More)
PURPOSE We analyzed the topography of proliferative diabetic retinopathy (PDR), and visualized the distribution of neovascularization of the optic disc (NVD) and elsewhere in the retina (NVE). METHODS The study included 174 eyes of 106 patients with early PDR. Data on the size and location of 391 NVE and 73 NVD were converted into a database of(More)
PURPOSE Despite being the third most common ABCA4 variant observed in patients with Stargardt disease, the functional effect of the intronic ABCA4 variant c.5461-10T>C is unknown. The purpose of this study was to investigate the molecular effect of this variant. METHODS Fibroblast samples from patients carrying the ABCA4 variant c.5461-10T>C were analysed(More)
