Active clinical trials for "Retinal Diseases"

In this study, we will be evaluating whether premedication with an anesthetic eye drops leads to a decreased sensation of pain when given dilating eye drops prior to eye examinations to evaluate for retinopathy of prematurity in neonatal intensive care unit (NICU) infants.

To assess the safety and efficacy of intravitreal aflibercept injection in the regression of retinal neovascularization secondary to high-risk PDR. To characterize baseline/post-induction/maintenance levels of proinflammatory mediators in patients with high-risk PDR

This is a feasibility study to assess the use of wide field adaptive optics optical coherence tomography (WF-AO-OCT) to determine whether there are structural differences in the peripheral retina in participants diagnosed with diabetic retinopathy compared to a healthy control group. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the WF-AO-OCT light source is well below maximum permissible limits for safe exposure.

Intravitreal injections of pegaptanib will induce the regression of Proliferative Diabetic Retinopathy (PDR) and reduce the need for retinal photocoagulation.

The purpose of the study is to evaluate the safety and efficacy of 2.5 mg of intravitreal bevacizumab in one eye, versus panretinal photocoagulation in the contralateral eye, for the treatment of patients with untreated symmetric proliferative diabetic retinopathy.

The patients who are diagnosed with idiopathic epiretinal membrane and scheduled to undergo epiretinal membrane removal will be treated with conventional vitrectomy and the epiretinal membrane will be removed. After removal of the epiretinal membrane, indocyanine green staining will be used to determine the internal limiting membrane (ILM) peeled off with the epiretinal membrane. (Group 1: spontaneous ILM peeling) If it is confirmed that the internal limiting membrane is not peeled together, the investigators determine whether the active Internal limiting membrane peeling is performed by 1:1 randomization immediately during surgery. (Group 2: Active ILM peeling, Group 3: no ILM peeling) The outcomes of the three groups will be compared.

In this randomized clinical trial, 100 eyes with nonproliferative diabetic retinopathy will be included and divided randomly into 2 groups: Intravitreal Bevacizumab group (50 eyes) that receive 6 bimonthly intravitreal bevacizumab, and control group (50 eyes) that undergo regular follow-up for Diabetic Retinopathy. Diabetic macular edema (DME) will be treated independently in all groups by intravitreal bevacizumab. Primary outcome will be the percentage of patients with progression of 2 or more stages through international diabetic retinopathy staging. The secondary measures will be changes in best corrected visual acuity (BCVA) and central macular thickness (CMT), and number of examinations and injection.

To assess whether neuroprotective drugs administered topically (somatostatin and brimonidine) are able to prevent or arrest the development and progression of neurodegenerative changes

The purpose of this protocol is to determine whether point of care optical coherence tomography (OCT) imaging combined with an OCT-guided retinal referral algorithm at primary diabetes care visits increases rates of retina specialist eye care for patients with diabetic macular edema. The hypothesis is that OCT imaging with an automated OCT-guided referral algorithm will enable identification of patients at risk for vision loss from diabetic macular edema and facilitate direct referral to retina specialists for more timely evaluation and treatment.

To investigate the feasibility and advantages of using perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting vitrectomy using a dual, dynamic drive (3D)technology. In complicated surgeries in advanced diabetic retinopathy and retinal detachment
