Imaging Retinal Vasculature in Infant Eyes

Retinopathy of Prematurity

Retinopathy of prematurity is a leading cause of childhood blindness worldwide. The fovea, a critical location in the retina determining visual acuity and visual function, and the blood vessels around it, are abnormally developed in infants with retinopathy of prematurity. However, how these blood vessels form during development of the human fovea remains unclear. This research will advance our understanding of the fundamental knowledge of how the blood vessels around the fovea form in infants, and how they change in diseased states such as preterm birth or retinopathy of prematurity.

Place of Glycation in Diabetic Retinopathy

Descriptor

Definition: Diabetic retinopathy is a microangiopathic complication of diabetes diabetes mellitus. Its pathophysiology includes glycation and intracellular hypoxia. Diabetic retinopathy (DR) is a microvascular complication of diabetes. It is the leading cause of It is the leading cause of blindness and visual impairment in people under the age of 60 in industrialized countries. Chronic hyperglycemia during diabetes plays a major role in the occurrence of diabetic diabetic retinopathy by promoting protein glycation and the accumulation of glycation end products (GTPs). GTPs are a heterogeneous group of compounds resulting from non-enzymatic and irreversible reactions between reducing sugars and amine groups of biological molecules such as proteins, lipids or nucleic acids. Interest: The aim of our work is to describe the mechanisms by which glycation participates in the pathophysiology of diabetic retinopathy and to discuss the use of AGEs as biomarkers in this biomarkers in this pathological context and the therapeutic means that limit the toxicity of of AGEs. The study is designed through a retrospective and prospective observational study to establish the of glycation in the occurrence of diabetic retinopathy. It will describe the demographic demographic profiles, glycemic control, clinical and paraclinical status of patients with diabetic diabetic retinopathy and will evaluate the relationship between glycation and diabetic retinopathy as well as the factors that influence this glycation in these patients, and induce the occurrence and / or of diabetic retinopathy. The data collected will allow to improve the knowledge, the diagnosis and the treatment of diabetic diabetic retinopathy, as well as a good management of the patients who should benefit from a more individualized and individualized and adequate treatment.

Effect of Vitrectomy on the Evolution of Refractory Diabetic Macular Edema

EdemaMacular Edema4 more

For patients with at least one eye with non-tractional diabetic edema refractory to 6 months of anti-VEGF injections (anti Vascular endothelial growth factor injections), a randomization is done: one group of patients will receive the standard treatment (anti-VEGF injections, switch to another anti-VEGF drug, additional photocoagulation or any other treatment except vitrectomy during the first 6 months after the randomisation) and the other group of patients will receive vitrectomy (with only additional photocoagulation during the first 6 months, then any treatment from 6 months after the randomization).

Retinopathy of Prematurity Both EyesRetinal Disease2 more

The Retinopathy of Prematurity (ROP) is one of the leading causes of blindness on the pediatric age worldwide. This pathology is characterized for arrest of the normal vascular and neuronal retina that because of pathological compensatory mechanisms results in proliferation of vascular tissue that grow in the limit between the vascular retina and the avascular retina. The ET-ROP group classified the ROP by those who need treatment immediately or those who doesn't need treatment, The classification is the following Type 1 ROP-->ROP zone I any stage with plus, zone I stage 3 without plus, zone II stage 2 y 3 with plus Type 2 ROP --> Zone 1, Stage 2 or 3 without plus, and Zone II, stage 3 without plus. The treatment is begun on patient with type 1 ROP and type 2 ROP is maintained in observation.

The Effect Evaluation of Continuous Nursing Intervention in Patients With Type 2 Diabetic Retinopathy...

Type 2 Diabetic Retinopathy

Objective: To evaluate the application effect of continuous nursing intervention in type 2 diabetic retinopathy (DR), and to explore its clinical application value. Methods:Patients with type 2 DR admitted to our Hospital from June 2019 to June 2022 were selected as the research objects and divided into intervention group and control group by random number table method. The control group received routine nursing intervention, and the intervention group received continuous nursing intervention on the basis of the control group. The related effect evaluation indexes such as fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin and visual acuity were collected and compared between the two groups at discharge, 1 year and 2 years after discharge. The readmission rate of the two groups was counted to evaluate the effect of continuous nursing intervention.

Diabetic Retina Exam Rate Does Not Increase With Phone Reminders in Non-HMO Population

Diabetic Retinopathy

Diabetic retinopathy is the major cause of blindness in working age Americans, and screening for it is cost-effective. There are a quarter of a million people in Southeast Michigan with diabetes and pre-diabetes. Only half of patients with diabetes are screened regularly for diabetic retinopathy, and this proportion has been difficult to increase despite various interventions. Previous research focused on HMO patient groups because preventative care was thought to decrease plan costs. In addition, it was administratively feasible to track patient-doctor interactions. This project builds on published research and institutional experience to determine an effective method for increasing the screening rate, in a mobile, non-HMO population. It uses administrative methods and information technology infrastructures, such as large scale electronic medical records and patient demographic databases, to identify existing patients requiring examinations. Patients were telephoned by a trained service representative who offered and scheduled firm examination appointment times. Hypothesis: Annual screening rates for diabetic retinopathy can be substantially improved in non-HMO patient groups by directly contacting patients and scheduling firm appointment times.

Effect of Diabetes Education During Retinal Ophthalmology Visits on Diabetes Control

DiabetesDiabetic Retinopathy

The purpose of this study is to assess whether glycemic control (assessed with HbA1c measurement) in individuals with type 1 or type 2 diabetes can be improved with a point-of-care measurement of HbA1c in the ophthalmologist's office combined with a personalized risk assessment for diabetic retinopathy and other complications of diabetes.
