Mitochondrial Retinopathies [PDF]

International Journal of Molecular Sciences, 2021
The retina is an exquisite target for defects of oxidative phosphorylation (OXPHOS) associated with mitochondrial impairment. Retinal involvement occurs in two ways, retinal dystrophy (retinitis pigmentosa) and subacute or chronic optic atrophy, which are the most common clinical entities. Both can present as isolated or virtually exclusive conditions,

Eclipse retinopathy [PDF]

Eye, 2001
Solar retinopathy is a well-recognised clinical entity of macular damage caused by viewing the sun, induced by a photochemical process. The term 'eclipse retinopathy' is frequently employed when the condition is sustained as a result of viewing a solar eclipse.

DIABETIC RETINOPATHY [PDF]

Medical Clinics of North America, 1998
Nonproliferative diabetic retinopathy may cause visual loss when associated with macular edema or macular ischemia (secondary to retinal capillary nonperfusion). Proliferative diabetic retinopathy may cause severe visual loss if complicated by vitreous hemorrhage or traction detachment of the macula.

High Glucose-Mediated Tyrosine Nitration of PI3-Kinase: A Molecular Switch of Survival and Apoptosis in Endothelial Cells

Antioxidants, 2018
Diabetes and hyperglycemia are associated with increased retinal oxidative and nitrative stress and vascular cell death. Paradoxically, high glucose stimulates expression of survival and angiogenic growth factors.

Laser treatment in diabetic retinopathy [PDF]

, 2007
Diabetic retinopathy is a leading cause of visual impairment and blindness in developed countries due to macular edema and proliferative diabetic retinopathy (PDR). For both complications laser treatment may offer proven therapy: the Diabetic Retinopathy

Neurodegenrative changes in retina of rats with chronic epileptic syndrome under conditions of treatment with niacin-oxy-ethylidene-phosphonate germanate (MIGU-4)

Journal of Ophthalmology, 2023
Background: Epilepsy is accompanied by neurodegenerative changes, particularly those in the retina. Elucidation of the mechanisms of retinal alterations in a model of epileptic syndrome may allow for the development of new approaches to pharmacological ...

Ultrastructure of neurovascular changes in human diabetic retinopathy [PDF]

, 2018
The previous concept regarding diabetic retinopathy assigned a primary role to hyperglycemia-induced microvascular alterations, while neuronal and glial abnormalities were considered to be secondary to either ischemia or exudation.

Dengue Virus Infection of Human Retinal Müller Glial Cells

Viruses, 2023
Retinopathy is a recently recognized complication of dengue, affecting up to 10% of hospitalized patients. Research on the pathogenesis has focused largely on effects of dengue virus (DENV) at the blood–retinal barrier.

Diabetic retinopathy [PDF]

Postgraduate Medical Journal, 1984
Involvement of the retinal microvascular vessels is an almost inevitable consequence of long standing diabetes. In the only large scale epidemiology study of a Caucasian population Klein et al. found some degree of retinopathy in up to 97% of patients with insulin dependent diabetes mellitus (IDDM) after about 15 years diabetes duration and in about 60%
