Outcomes of Diabetic Retinopathy Post-Bariatric Surgery in Patients with Type 2 Diabetes Mellitus

2021

Bariatric surgery is an emerging therapeutic approach for obese type 2 diabetes mellitus (T2DM) patients, with proven benefits for achieving target glucose control and even remission of diabetes. However, the effect of bariatric surgery upon diabetic retinopathy is still a subject of debate as some studies show a positive effect while others raise concerns about potential early worsening effects. We performed a systematic review, on PubMed, Science Direct, and Web of Science databases regarding the onset and progression of diabetic retinopathy in obese T2DM patients who underwent weight-loss surgical procedures. A total of 6375 T2DM patients were analyzed. Most cases remained stable after b…

282 Ophtalmologic follow-up of diabetic patients managed by Gps or diabetologists: results of FOCUS survey

2011

ObjectiveTo describe the ophthalmological follow up and cardiologists-nephrologists’ involvements in diabetic patients managed by GPs or diabetologists.MethodsTransversal and observational survey conducted in 2009, by 1112 GPs and 188 specialists.Results2577 diabetic patients (T1D or T2D) have been included; 63% were males, and mean age was 62 years. Mean diabetes duration was 10 years. Most of them were hypertensive (72%), 68% had a dyslipidemia and 30% a non proliferative diabetic retinopathy. Nearly all patients have been followed by ophthalmologists (70% have been seen once a year).In patients having a diabetic retinopathy (DR), treatments have been intensified in 80% of them with a vis…

Retinopathy of prematurity-current diagnosis and management

1993

Despite advances in ophthalmological care of premature infants, retinopathy of prematurity (ROP) remains a still unsolved problem for paediatricians as well as ophthalmologists. A survey of the current literature concerning drug therapy and surgical management as related to the different stages of ROP is given. The classification system for ROP according to the International Committee is presented as well as our screening policy in relation to the literature. The effectiveness in preventing severe cases of ROP and the toxicity of vitamin E supplementation in high-risk premature infants is still disputed and no recommendations can be given. Cryotherapy is recommended in symmetric cases of st…

GLP-1 receptor agonists, carotid atherosclerosis and retinopathy

2017

It is known that diabetes is associated with the development of premature atherosclerosis and microvascular complications and consequently increased cardiovascular (CV) morbidity and mortality. In ...

Ocular angiogenesis: translating preclinical indications to successful clinical development

2004

Angiogenesis-related ocular diseases such as age-related macular degeneration (AMD) or diabetic retinopathy have a high socioeconomic impact in western countries and are the leading causes of blindness. Conventional treatment modalities for AMD are of limited success. Inhibition of new vessel formation and targeting of pathological vessels seem to be the best choice in AMD. A variety of animal models mimic the relevant aspects of choroidal neovascularisation (CNV) and allow for therapy screening. Preclinical and clinical studies show that a variety of different strategies are very promising. Stategies include inhibition or blocking of vascular endothelial growth factor, a key player in angi…

Efficacy and Safety of Subthreshold Micropulse Yellow Laser for Persistent Diabetic Macular Edema After Vitrectomy: A Pilot Study

2022

Aim: To examine the effect of subthreshold micropulse yellow laser (SMYL) on best-corrected visual acuity (BCVA), central macular thickness (CMT), and optical coherence tomography angiography (OCT-A) changes in eyes with persistent diabetic macular edema (DME) after pars plana vitrectomy (PPV) for tractional DME (TDME).Patients and Methods: In a comparative study, 95 eyes of 95 consecutive patients with persistent DME were prospectively enrolled. The SMYL group (54 eyes) was treated with SMYL 6 months after PPV, while the control group (41 eyes) was followed up without treatment. BCVA and CMT by OCT were analyzed at baseline and 3 and 6 months. Additionally, parameters such as the vessel de…

Tears as a source of biomarkers for ocular and systemic diseases

2013

The main focus in clinical proteomics is the discovery of new protein or peptide biomarkers which are correlated with a certain disease. Tear proteins have been investigated extensively in the past and distinct relations between the levels of certain tear proteins to different disorders have been demonstrated. In this review we attempt to summarize proteomic technologies for biomarker identification in tears and some disease related biomarkers in tear fluids that were discovered through different proteomic techniques in different conditions like dry eye, Sjogren's syndrome, contact lens wearers, glaucoma, diabetic retinopathy or cancer. Proteomic analysis of tear fluid has proven to be a pr…

Target oxygen levels in preterm neonates

2013

To achieve postnatal adaptation newly born infant need to aerate the lungs, reduce pulmonary vascular resistance, and initiate oxygen and carbon dioxide exchange. The cornerstone of newborn resuscitation resides therefore in the establishment of a functional residual capacity and an adequate oxygenation. Recent guidelines have established guidelines concerning oxygen supplementation in preterm infants in the delivery room (DR); however, they are vague and unspecific. Herewith, we will address available information regarding the use of oxygen supplementation in the DR in preterm infants to satisfactorily overcome postnatal adaptation. Introduction: Resuscitation of the newborn is considered …

Retinal ultrastructure of neuronal ceroid-lipofuscinosis in the Dalmatian dog

1985

Ultrastructural studies of the retinae in two NCL-affected Dalmatian dogs revealed ubiquitous accumulation of lipopigments in numerous cell types of the retina, the fine structure of which closely resembled that seen in NCL-affected English setters. Photoreceptors and other retinal cell types were largely intact. These findings show that the retinal involvement in NCL of our Dalmatian dogs is identical to that of NCL-affected English setters. It also shows that in canine NCL a severe retinopathy, regularly encountered in human childhood NCL, does not develop. Thus, the NCL of Dalmatian dogs —and English setters — represents a reliable model to study human NCL, but for human retinopathia pig…
