Active clinical trials for "Diabetic Retinopathy"

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.

Purpose: To compare panretinal photocoagulation (PRP) as described in ETDRS Study combined with intravitreal injection of ranibizumab (IVR) (ETDRS-PRP group) and retinal photocoagulation targeted to ischemic retina combined with IVR (ISQ-RP group) in patients with proliferative diabetic retinopathy (PDR). Design: Randomized prospective clinical trial. Methods: Patients with PDR were assigned to receive either PRP plus IVR (20 eyes) or retinal photocoagulation targeted to ischemic areas plus IVR (20 eyes). ETDRS best-corrected visual acuity (BCVA), central subfield macular thickness (CSFT) measured by optical coherence tomography (OCT) were performed at baseline and every 4 weeks through week 48. Area of fluorescein leakage from active new vessels (FLA) was measured every 12 weeks. Full-field electroretinography (ERG) was recorded at baseline and after 3 months.

This study is conducted to evaluate the safety of THR-317 when administered intravitreally and to assess the compound's efficacy in improving best-corrected visual acuity (BCVA) and reducing central subfield thickness (CST) in subjects with centre-involved diabetic macular oedema (DME).

Purpose: To evaluate the clinical efficiency, safety and painfulness of retinal laser photocoagulation employing a pattern scanning laser system Pascal given in a single-session versus conventional laser multiple-session treatment of the same patient with diabetic retinopathy. Methods: The cohort included 60 eyes in 30 patients treated at the Ophthalmology Clinic, Faculty Hospital Ostrava, from 2008 to 2013. Panretinal laser coagulation was performed on one eye using the multispot panretinal photocoagulation given in a single-session system Pascal (SSP) (OptiMedica, Santa Clara, California). On the other eye laser treatment was carried out by the classic conventional multiple-session method (MSM).

The present study aims to support previous research on antioxidant therapy effects in diabetic retinopathy outcome. The investigators intend to assess 180 patients with diabetic retinopathy in different stages (moderate, severe and proliferative), whom either will be assigned to placebo group or combined antioxidant therapy. Each group will receive the intervention for 12 months. Such intervention consists in taking one tablet (placebo or antioxidant therapy) orally, a day. At baseline, blood and urine samples will be collected in order to assess metabolic and oxidative stress status, mitochondrial function or dysfunction, liver and kidney function. In addition, fluorescein angiography will be done for the categorization of diabetic retinopathy. After six months and at the end of the intervention, blood and urine measurements as well as angiographies will be done for comparing the outcomes between both groups and correlate oxidative stress status, mitochondrial dysfunction with grade of retinopathy.

This study is conducted to evaluate the safety of a single intravitreal injection of THR-149.

Efficiency and effectiveness of real-world diabetic retinopathy screening by artificial intelligent (AI) are limited. Investigators will implement AI for diabetic retinopathy screening in 13 health districts in Thailand and investigate the efficiency, effectiveness as well as patients and health care personnel's satisfaction by an implementation research.

In recent years, vitrectomy has moved toward a minimally invasive vitrectomy surgery (MIV) system, which could effectively reduce the occurrence of operation complications, while reducing the time of post-operation recovery. With an improved design of bevel tip and a high cutting rate capacity of 10000cpm, Advanced ULTRAVIT® probes potentially provide an strong technical support for the application of MIV. The new probe facilitates great control during delicate surgical maneuvers, such as separating the hyaloid from the retinal surface, dissecting fibrovascular tissue off the surface of retina. However, there was no sufficient clinical evidence to support the benefits of Advanced ULTRAVIT ® probes in the complicated vitreoretinal surgery, such as proliferative diabetic retinopathy. More importantly, there is an urgent need of clinical evidence to support 10000cpm launch and conversion which is major objective of 2021 VR growth strategies.

This study is a retrospective study to assess the efficacy and accuracy of the EyeCheckup software in screening for diabetic retinopathy in healthcare settings.

The purpose of this study is to characterize the systemic and ocular safety and tolerability, pharmacokinetics, exploratory efficacy and pharmacodynamics of 3 months of repeat administration of oral darapladib in diabetic macular edema patients with centre involvement.
