Filter by:The purpose of this study is to test whether ACULAR, a nonsteroidal anti-inflammatory eye drop medication, can prevent the development of retinopathy of prematurity (ROP) and/ or decrease its severity.In this study ACULAR will be compared to a placebo (artificial tear). The hypothesis would be that ACULAR treatment will decrease the incidence of moderate to severe ROP (grade II and above)by 50%.
Patients with neovascular Age-related macular degeneration (AMD) and the particular feature of pigment epithelial detachments (PEDs) were not studied in the Phase III trials for ranibizumab (Lucentis). The PrONTO study was the first ranibizumab study to enroll such patients but only treated with ranibizumab until fluid within the layers of the retina was absent, not until the entire PED was absent. This study hypothesizes that there may be a difference in benefit between patients treated until just the retinal edema is gone and those in which the retinal edema and PED are both gone.
Vitreoretinal surgery for epiretinal proliferation tractional retinal detachment associated with proliferative diabetic retinopathy (PDR) is often complicated by hemorrhage from fibrovascular tissue. To control the bleeding during tissue dissection multiple measures and techniques are used. Bevacizumab is an anti VEGF antibody which has been used to induce regression of ocular neovascularization. Its intraocular injection has been increasingly used for treatment of choroidal neovascularization (CNV) associated with age related macular degeneration (AMD) with fairly good success.Also it has been shown to be effective for treatment of PDR complicated with vitreous hemorrhage and iris neovascularization. We hypothesized that if anti-angiogenic agents, such as bevacizumab are injected into the vitreous cavity before vitrectomy in cases of PDR; there may be partial regression of neovascularization resulting in less intraoperative (and postoperative) hemorrhage. This can make the operation easier and shorter and lessen the need for intraocular cautery.. In this study diabetic patients who are candidated for vitrectomy with similar complexity scores will be randomized to preoperative injection or no injection of 2.5 mg Bevacizumab .In the injection group, 2.5 mg of bevacizumab (0.1 ml of commercially available Avastin vial, Genentech, inc. South San Francisco, CA) will be injected into the vitreous 3-5 days before operation. During each operation, the number of endodiathermy applications, backflush needle applications and the duration of surgery will be recorded by an independent observer. Also, type of tamponade, post operation vitreous hemorrhage and 3 months postoperative visual acuities wil be recorded. all these parameters will be compared in two groups.
To undertake a prospective randomized clinical study for treating retinal detachment due to myopic macular holes, utilizing pneumatic retinopexy versus pars plana vitrectomy with gas tamponade.To determine the efficiency of pneumatic retinopexy with C3F8 in the treatment of retinal detachment due to myopic macular hole.
To investigate the feasibility and advantages of using pressurized perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting 23 GA vitrectomy using a dual, dynamic drive (3D)technology, in complicated retinal detachment surgeries.
The purpose of the study is to compare the safety, intraocular adverse effects and the anatomic and functional outcome with two endotamponade silicone oil after a 3-month in complex inferior retinal re-detachments.
To compare the visual and anatomical outcomes and complications of four surgical techniques (1- scleral buckling, 2- primary vitrectomy without encircling band, 3- primary vitrectomy with encircling band, 4- triamcinolone assisted vitrectomy) for management of pseudophakic and aphakic retinal detachment
This clinical trial will test the efficacy and safety of oral colchicine in prevention of proliferative vitreoretinopathy (PVR) in cases of rhegmatogenous retinal detachment
Assess recovery of macula function after successful scleral buckling surgery for rhegmatogenous retinal detachment by using the multifocal ERG in the postoperative period i.e. recovery of functional integrity 2. Assess the relationship between the neurosensory retina and the retinal pigment epithelium/choriocapillaris after scleral buckling i.e. recovery of structural integrity 3. Assess if there is a difference between macula function postoperatively, in eyes with retinal detachments involving the macula and those that do not.
Premature infants stand a risk of danger to the layer of the eye that creates sight that, if untreated, can cause severe vision problems, leading to blindness in some cases. This research study will use ultrasound to examine the eye for retinal changes of prematurity.
