Non-proliferative Diabetic Retinopathy

2014
Non-proliferative diabetic retinopathy (NPDR) is defined by the presence of early intraretinal microvascular findings and is currently classified into different stages of severity, according to international proposed classifications. The Early Treatment Diabetic Retinopathy Study Research (ETDRS) Group showed that very severe NPDR has an increased risk

Retinal vasculature–function correlation in non-proliferative diabetic retinopathy

Documenta Ophthalmologica, 2019
To compare and correlate retinal microcirculation and function in patients with non-proliferative diabetic retinopathy (NPDR).Thirty-three healthy controls (33 eyes), 36 diabetic patients with no clinically detectable retinopathy (NDR, 36 eyes) and 101 patients (101 eyes) with NPDR (35 mild NPDR, 34 moderate NPDR, 32 severe NPDR) were involved in the ...

Non-proliferative diabetic retinopathy detection using mathematical morphology

2018 IEEE 4th Middle East Conference on Biomedical Engineering (MECBME), 2018
Diabetes might be the cause of lots of visual troubles (when it is poorly controlled); it induces the thickening and hardening of the retina's blood vessels and prevents the accomplishment of its function suitably. Among the complications of diabetes on the eye, there is the diabetic retinopathy, which is considered as a major cause of blindness in the

Proliferative retinopathy in non-diabetic patients

Documenta Ophthalmologica, 1971
36 non-diabetic patients with preretinal or prepapillary proliferations were examined. Nearly all patients had changes of the arteries due to arteriosclerosis or hypertension. In 22 patients the vascular new-formations were located on a level with the retina and they were anastomoses between the retinal vessels.

Retinal Vessel Segmentation of Non-Proliferative Diabetic Retinopathy

International Journal of Applied Evolutionary Computation, 2019
Diabetic retinopathy is a disease in diabetic patients that affects the eye. It happens due to damage in the blood vessels of the light-sensitive tissues at the retina. In non-proliferative diabetic retinopathy, tiny changes occur in the blood vessels of the eye. Non-proliferative diabetic retinopathy can trigger macular edema or macular ischemia.

Oct biomarkers of treatment-naive diabetic macular edema in patients with non-proliferative and proliferative diabetic retinopathy

European Journal of Ophthalmology, 2022
Purpose To evaluate and compare the retinal and choroidal spectral-domain optic coherence tomography (SD-OCT) findings of treatment-naïve diabetic macular edema (DME) secondary to non-proliferative and proliferative diabetic retinopathy (NPDR-PDR). Material and methods A hundred and thirty-eight eyes of 138 patients with DME were evaluated.
