Active clinical trials for "Retinal Detachment"

The purpose of this open, multicenter trial is to assess the impact of the use of an amniotic membrane graft on the closure of macular hole-associated retinal detachment in patients with failed previous macular surgery.

To evaluate efficacy of vitrectomy with inverted internal limiting membrane (ILM) flap technique for macular hole retinal detachment (MHRD) in highly myopic eyes, and to demonstrate postoperative clinical course of MHRD after inverted ILM flap technique using swept-source optical coherence tomography (OCT)

Internal limiting membrane peeling is performed during vitrectomy for macular diseases such as macular holes, macular edema due to diabetic retinopathy and retinal vein occlusion. The incidence of epiretinal membrane formation after vitrectomy for rhegmatogenous detachment has been reported to range from 4.4% to 12.8%. In this study, the efficacy and safety of internal limiting membrane peeling will be studied in vitrectomy for rhegmatogenous retinal detachment and if it is essential to peel it in those cases or not.

Background : Surgery is needed in order to flatten and position a detached retina onto the choroid, to allow sealing of the tears and to prevent or reverse vision loss. In case of complex retinal detachment vitrectomies followed by ocular endotamponade - non-solid implants used in ophthalmology - is the most common treatment. Despite several options used by surgeons were not entirely satisfactory, no innovation were marketed in the ocular endotamponade field since decades. Purpose : Regarding comparative physico-chemical properties of medium-chain triglycerides (MCT) with current tamponading agents (silicone oil or gases), it will be proposed to evaluate the MCT as an ocular endotamponade product.

The purpose of this is study is to assess the efficacy of pre-operative intravitreal bevacizumab (IVB) (Genentech, South San Francisco CA) in improving visual acuity, reducing operative time, complications, intra-operative and post-operative hemorrhage following small gauge pars plana vitrectomy (PPV) (23-gauge, 25-gauge or 27-gauge ) compared to small gauge PPV (23-gauge, 25-gauge or 27-gauge) alone in eyes with tractional retinal detachment (TRD) secondary to proliferative diabetic retinopathy (PDR). Hypothesis: Preoperative IVB may be beneficial for membrane dissection in diabetic tractional retinal detachment with minimally invasive vitreoretinal surgery (23-gauge transconjunctival sutureless vitrectomy [TSV]). In addition, post-operative rebleeding may be decreased.

This study will evaluate the use of intravitreal aflibercept (anti-VEGF therapy) in patients with a type of macular degeneration known as vascularized pigment epithelial detachment. Previous studies have shown a generally poor outcome in treating this difficult to treat form of wet macular degeneration. More recently, multiple pilot studies have shown positive benefits to using anti-VEGF therapy. This study will evaluate the safety and efficacy of treating vascularize pigment epithelial detachment associated with wet macular degeneration with intravitreal aflibercept injection.

The fibrin sealants are prepared from fibrinogen, thrombin, and sometimes factor XIII that have been purified from human plasma. Tissucol Duo Quick (Baxter, Vienna, Austria) is a kind of fibrin sealants with popular use. It is a 2-component tissue adhesive that resembles natural fibrin formation. This glue has 2 components: fibrinogen (mixed with factor XIII and aprotinin) and thrombin-CaCl2 solution. When equal amounts of the 2 components are mixed, the monomers aggregate by cross-linking, resulting in a fibrin clot. It forms a elastic, whitish substance and provides strong adhesion to the tissue. Therefore, it is a good agent to seal small wounds or to replace the use of suture.

It has been hypothesized that potential effects of laser Nd: YAG laser posterior capsulotomy may affect macular pigment as well as choroidal thickness, macular thickness and anterior chamber parameters, so it was aimed to investigate possible effects of Nd: YAG laser posterior capsulotomy on macular pigment optical density, choroidal thickness, macular thickness and anterior chamber parameters in cases with posterior capsule opacification in this study.

Objective: to evaluate anatomical and visual outcomes of 23-gauge vitrectomy for retinal detachment with silicone oil injection in fifty cases. The rate of recurrence, the incidence of proliferative vitreoretinopathy (PVR) and the value of risk factors. Participants and Methods: fifty cases with RD with mixture of epiretinal and subretinal membranes were collected. Pars plan vitrectomy, 23gauge vitrectomy were done to these cases, then silicone oil removed 6 weeks after primary surgery. Main Outcome Measures: The anatomical success rate,the failure rate ,the rate of retinal breaks in both groups, and reproliferation rate.

To compare the efficacy and safety outcomes of scleral buckling (SB) and drainage-injection-pneumoretinopexy (DIP), a modified pneumatic retinopexy technique, in which, before injecting the gas, the drainage of the subretinal fluid is performed with a simultaneous injection of balanced salt solution (BSS) in the vitreous chamber, for the treatment of severe superior bullous rhegmatogenous retinal detachment (SBRD).
