purpose : chlamydia pneumonia is a known endothelial pathogen in several vascular diseases including atherosclerosis, age-related macular degeneration and non-arteritic anterior ischemic optic neuropathy. diabetic retinopathy is a retinal vascular disease that may similarly be affected. we serologically investigated the presence of c. pneumonia infection in patients with proliferative diabetic ...

Cerebral malaria (CM) can be classified as retinopathy-positive or retinopathy-negative, based on the presence or absence of characteristic retinal features. While malaria parasites are considered central to the pathogenesis of retinopathy-positive CM, their contribution to retinopathy-negative CM is largely unknown. One theory is that malaria parasites are innocent bystanders in retinopathy-ne...

Diabetic retinopathy involves anatomic changes in retinal vessels and neuroglia. The pathogenetic mechanism responsible for retinopathy is imperfectly understood, but much of the mechanism is apparently reproduced by experimental diabetes in animals and by chronic elevation of blood galactose in nondiabetic animals. The evidence that retinopathy is a consequence of excessive blood sugars and th...

BACKGROUND Atherogenic lipoproteins, such as total cholesterol, LDL cholesterol, oxidized low density lipoprotein, and triglycerides, are associated with progression of retinopathy. Aim. To evaluate the relationship between lipoprotein(a) and retinopathy in patients with type 2 diabetes mellitus. MATERIALS AND METHODS We enrolled 145 diabetic consecutive patients (82 females, 63 males; mean a...

purpose : visual loss associated with multiple traumas in the context of road traffic accident, especially when the maxillofacial and orbital areas are not directly injured, is an uncommon occurrence. the possibility of purtscher’s retinopathy, i.e. retinal manifestation of mechanical trauma elsewhere in the body, as the cause of visual disturbance in these situations can often be overlooked. p...

OBJECTIVE To quantify the variability of scotomas detected by 10-2 visual field (VF) testing in patients taking hydroxychloroquine without and with retinopathy. DESIGN Retrospective review of clinical charts and visual fields. SUBJECTS Twenty-one patients taking hydroxychloroquine without retinopathy, and nine patients taking hydroxychloroquine and one patient taking chloroquine with retino...

Background: This study aimed to determine the prevalence of Diabetic Retinopathy and find associated risk factors DR among known Type II DM patients. Materials Methods: A hospital-based cross-sectional single center was conducted patients with without in department Endocrinology a sample size 150 2018. Data were expressed as mean, standard deviation, proportions, Chi-Square, t-test test Binary ...

extractdefective corneas are the leading cause of blindness world wide and the second leading cause, after diabetic retinopathy,of blindness in the united state , afflicting 30000 americans each year. happily, nearly 95 percent of those who have corneal transplantations( in 1985 they numbered,26300) regain their sight. the cornea is a transparent, a vascular, dim-sized tissue continious with th...

A 19-year-old woman who sustained multiple trauma but no head injury developed fulminant fat embolism syndrome (FES). Her neurological deterioration was associated with cerebral oedema and the concomitant Purtscher's type retinopathy. We suggest that the pathogenesis of the retinopathy and of the cerebral oedema are the same and that Purtscher's retinopathy and retinopathy of the FES are indist...

AIM To investigate L-selectin expression and shedding in patients with and without retinopathy and to determine if any observed changes are reflected by a functional change in the adhesion of leucocytes to an endothelial monolayer. METHODS Age matched diabetic patients (26 with retinopathy, 19 without retinopathy) were compared to 24 non-diabetic controls to determine L-selectin surface prote...
