Retina Clinical Trials

This study will utilize three strata called Stratum I, Stratum II and Stratum III. STRATUM I - Infants and children known to have leukocoria who have been diagnosed with retinoblastoma, cataracts or glaucoma or other eye conditions. Participants enrolled on Stratum I of the study will have the CRADLE application ...

Conservative treatments of retinoblastoma (RETINO 2011) -Multicentric non randomised, phase II study for the patients treated by chemoreduction (VP16, carboplatin) followed by chemothermotherapy without laser treatment at day 8 -Multicentric non randomised, phase II study for the patients with bilateral very asymmetric dis-ease (Group D eye on one of the ...

Severe vision loss in patients with proliferative diabetic retinopathy (PDR) frequently results from complications related to neovascularization and fibrovascular proliferation. Patients with PDR are typically considered candidates for pars plana vitrectomy (PPV) when non-clearing vitreous hemorrhaging, tractional retinal detachment (TRD) development or extensive fibrovascular proliferation occur. Visual prognosis is guarded ...

The intra-vitreous injection (IVT) of anti-VEGF (vascular endothelial growth factor) is currently the standard treatment for retinal neovascularization. The VEGF stimulates endothelial cells' proliferation and migration. It also increases microvascular permeability. If the VEGFs have proven their efficiency in the decrease of choroidal neovascular proliferation, their impact of the head ...

The treatment of neovascular age-related macular degeneration (ARMD) is a major issue of public health. The therapeutic arsenal has widely grown throughout the years with the emergence of intra-vitreous anti-angiogenic treatments, under different surveillance protocols. The "PRN" surveillance (pro re nata: an on-demand treatment with monthly follow-up) allows a faster ...

Pupil light reflex (PLR) will be measured by a chromatic multifocal pupillometer in response to short and long wavelength light with small spot stimulus in 76 points of the 30 degree visual field. A computerized infrared video pupillometer will be used to record changes in pupil diameter in response to ...

The purpose of this study is to determine if the reparative cells of blood vessels, called endothelial progenitor cells (EPC's) are defective in people with diabetes. Diabetic retinopathy (DR) is an eye disease related to diabetes. It can cause blurred vision and possible bleeding in the blood vessels in the ...

Diabetic retinopathy (DR) is a disabling microvascular complication. Despite recent advances using pharmacotherapy, a cure for DR has yet to be realized. Thus, a conceptual and technical breakthrough to identify novel targets, and a strategy to cure this complication is paramount. We believe that the recent clinical evidence from large ...

Vascular complications due to diabetes mellitus (DM) are the result of sustained vascular injury with insufficient vascular repair. In chronic diabetes, vascular reparative mechanism can be lost resulting in development of microvascular complications (MVC), such as diabetic retinopathy (DR). We assessed the reparative function of progenitor cells that circulate in ...

This study evaluates the effect of melatonin 4 mg on circadian rhythm and visual function of patients with diabetes mellitus. Half of the patients will receive melatonin (arm-1) and the other half will receive placebo (arm-2), both groups in 3 weeks. After a week of washout, the patients will cross ...
