Active clinical trials for "Retinal Detachment"

Proton beam therapy is a safe irradiation modality for choroidal melanoma. But often after irradiation the exudation increases resulting in an exudative retinal detachment requiring vitreoretinal surgery. It is known that intravitreally injected triamcinolone and TTT is capable to decrease the exudation. If there is any advantage in a combined treatment this study will investigate.

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.

Purpose: to assess the efficacy and safety of double tamponade versus silicone oil tamponade. Design: parallel-group study with balanced [1:1] stratified block randomization. Eligible participants are all adults aged 18 or over with first diagnosed rhegmatogenous total retinal detachment with retinal breaks located both in upper and lower retina. Also investigators include those patients with total retinal detachment with proliferative vitreoretinopathy (PVR) in which it is impossible to remove epiretinal membranes completely during the surgery (with arbitrary retinal breaks localization). Exclusion criteria are severe concomitant eye pathologies (glaucoma, diabetic retinopathy, macular hole, traumas etc) and eye length more than 27mm. Patients are randomized in two groups (test group and control group). In the test group patients undergo subtotal vitrectomy, epiretinal membrane removal, perfluorodecalin (PFD) tamponade, retinal photocoagulation. After that the surgeon replaces ½ of PFD volume by "conventional" SO (with density less than one of water). The result is vitreous cavity (VC) filled in a half with PFD and in another half - with SO. In the control group patients undergo subtotal vitrectomy, epiretinal membrane removal, PFD tamponade, retinal photocoagulation and PFD-SO exchange, so the result is VC filled with "conventional" or heavy SO, depending on predominant retinal breaks location. 30 days after the surgery in both groups tamponing agents are removed from VC and VC is filled with sulfur hexafluoride gas (SF6) which dissolves during 1 month. Follow-up is at least 12 months. Along with standard examinations, after SF6 gas dissolution investigators perform spectral optical coherence tomography (OCT) and microperimetry. With OCT investigators measure thickness of retinal inner and outer nuclear layers. With microperimetry investigators determine light sensitivity in 12° and 4° zones from the fixation point. Outcome measures: reattachment rate, best corrected visual acuity (BCVA), intraocular pressure (IOP), thicknesses of inner and outer nuclear layers according to the OCT, light sensitivity according to microperimetry, the rate of cataract formation in phakic eyes and the rate of tamponing agents emulsification. For final analysis each group will include 145 participants. OCT, microperimetry data and visual acuity will be compared between the groups using Student's t-test; proportions will be compared using exact Fisher's test.

This clinical trial will test the efficacy and safety of oral colchicine in prevention of proliferative vitreoretinopathy (PVR) in cases of rhegmatogenous retinal detachment

31 patients were included in the study,15 cases with ERM in silicone filled eyes and 16 eyes with idiopathic ERM

Macular hole surgery were tried by different surgeons using many techniques with different successes but still there were many recurrences. In this study the investigators try to close these distinct types including recurrent holes using pre-prepared amniotic membrane.

The purpose of this study is to evaluate whether postoperative postures influence persistent sub-foveal fluid after scleral buckle surgery

There are multiple ways to treat retinal detachment, the aim of this study is to compare the amount of corneal endothelial cell loss after pneumatic retinopexy in comparison to vitrectomy.

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

The investigators hypothesize that bevacizumab instilled into the vitreous after primary retinal detachment surgery will reduce the formation of proliferative vitreoretinopathy and subsequent retinal re-detachment.
