Filter by:This study determined the clinical impact and causes of loss to follow-up (LTFU) from the patients' perspective in individuals with proliferative diabetic retinopathy (PDR) who received panretinal photocoagulation (PRP) and/or intravitreal injections (IVIs) of anti-vascular endothelial growth factor (VEGF). This prospective cohort study included 467 patients with PDR who received PRP and/or IVIs of anti-VEGF between May 2013 and June 2018. LTFU was defined as missing any follow-up visit for any interval exceeding 6 months, provided that patients eventually resumed care. Main outcome measures include rates and causes of LTFU.
Citicoline (cytidine-5'-diphosphocholine) is an essential precursor in the synthesis of phosphatidylcholine, a component of cell membranes. Several experimental in vitro and in vivo studies have suggested that citicoline plays a neuroprotective role. A recent clinical study has shown that treatment with topical citicoline induces, after 60 days of therapy, a significant improvement in the ganglion cell function .In addition topical citicoline has been demonstrated in vivo a neuroprotective effect in preventing diabetic retinopathy . The Investigators want to evaluate if citicoline may reduce the progression of retinal damage in patients with mild diabetic retinopathy.
The objective of this study is to evaluate the safety and image quality of the investigational dye, MB-102, compared to the control dye (fluorescein sodium) in healthy and diseased eyes using fluorescent angiography for retinal vascular disease diagnosis and monitoring.
Commonly know that one of the complications caused by Diabetes Mellitus (DM) is microangiopathy. Microangiopathy in the long term may lead to neuropathy of the corneal nerves. Neuropathy of the cornea will lead to dry eyes in DM patient. One of the artificial tears used in treating dry eyes is sodium hyaluronate. But until recently no research had been done in examining the effect of giving combination of sodium hyaluronate, vitamin A and vitamin E in dry eyes. The antioxidant, and capability of vitamin A and E in promoting cell proliferation may alleviate the symptoms of dry eyes. In this paper we used Ocular Surface Disease Index (OSDI), Tear Break Up time, Schirmer I test and impression cytology to assess baseline and 28 days post therapy in patient with Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR)
To evaluate the safety and performance of an innovative artificial intelligence based Computer-Aided Diagnosis(CAD) system for diabetic retinography, Retinal images of patients with diabetes mellitus or diabetic retinopathy(DR) were collected retrospectively. All images were graded by a retinal specialists expert panel and the CAD device using the International Clinical Diabetic Retinopathy severity scale criteria. Investigator responsible for DR grading by CAD system is blinded to the DR grading results from the expert panel. Finally, DR grading results of the CAD system and experts were compared using sensitivity and specificity.
The object of this study is to investigate the damage to the retinal nerve fiber layer (RNFL) and ganglion cell complex layer (GCL+) in diabetic patients without retinal microangioma as detected by fundus fluorescein angiography (FFA) and to determine the kind of nerve damage more likely to indicate early injury.
This was a multicentre, randomised, double-blind controlled study that compared the efficacy and safety of V. vinifera extract, calcium dobesilate (CD), and placebo in subjects with DME. Patients made 6 clinic visits, namely the screening visit; baseline visit (T0); and follow-up visits at 3 (T3), 6 (T6), 9 (T9), and 12 (T12) months.
The purpose of this clinical study is to evaluate the long term safety and efficacy of cooling anesthesia application to the eye as anesthesia for intravitreal injection using a novel cooling anesthesia device.
Diabetic retinopathy (DR) is a leading cause of vision loss in working-age Americans. Capillary damage from hyperglycemia causes vision loss through downstream effects, such as retinal ischemia, edema, and neovascularization (NV). Proper screening and timely treatment with laser photocoagulation and anti-vascular endothelial growth factor (VEGF) injections can minimize morbidity. In the last decade, clinicians have been able to use objective structural data from optical coherence tomography (OCT) to guide the treatment of diabetic macular edema. Other aspects of care, however, still largely depend on subjective interpretation of clinical features and fluorescein angiography (FA) to determine the disease severity and treatment threshold. The recently developed OCT angiography (OCTA) provides dye-less, injection-free, three-dimensional images of the retinal and choroidal circulation with high capillary contrast. Not only is it safer, faster, and less expensive than conventional dye-based angiography, OCTA provides the potential of giving clinicians objective tools for determining severity of disease by detecting and quantifying NV and non-perfusion.
In this clinical trial, we plan to evaluate the usefulness of artificial intelligence (AI) software paired with a handheld retinal camera to compare diabetic retinopathy status in Bolivian patients as read by retina specialists versus the AI software.
