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,

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.

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.

Successful Management of a Patient with Florid Diabetic Retinopathy [PDF]
, 2016 Florid diabetic retinopathy is an unusual, aggressive type of diabetic retinopathy. It is seen in young patients with poor metabolic control. Despite advances in treatment the overall prognosis of this condition remains poor. A 21-year old female patient

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.

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%
