Filter by:Management of primary retinal detachment due to upper retinal break is one of controversial situation that may face ophthalmologists in vitreoretinal subspecialty.
Intraocular tamponade used in vitrectomy operations may affects retinal function in various mechanisms.
Intravitreal topotecan has anti-inflammatory, anti-proliferative and anti-fibrotic activity that we hypothesize may exhibit high efficacy for the treatment of proliferative vitreoretinopathy (PVR) in patients with rhegmatogenous retinal detachment (RRD). A high efficacy for intravitreal topotecan has been exhibited in cell cultures of PVR. At the same time, intravitreal topotecan has been routinely used in the treatment of vitreous seeds from retinoblastoma. At doses of 5-30 micrograms per injection, no adverse events have been reported with the use of intravitreal topotecan. Therefore, the current prospective matched phase II trial aims to investigate the efficacy and safety of intravitreal topotecan for severe PVR in patients with RRD.
Pars-plana vitrectomy (PPV) is the cornerstone of surgical treatment for eyes with complicated proliferative diabetic retinopathy. Anti-VEGF intravitreal injection before PPV has shown a good effect on surgical outcomes. However, many patients present with co-morbidities that contraindicate the usage of anti-VEGF in the pre-operative period. Thus, cryoapplication, an old therapeutic tool for proliferative diabetic retinopathy may be a good alternative. The investigators present herein a comparative study between peripheral retinal cryoapplication and anti-VEGF before vitrectomy for complicated proliferative diabetic retinopathy.
To demonstrate that intraoperative use of subtenon triamcinolone acetonide at the time of surgery without postoperative eye drops is non-inferior to the regimen of postoperative eye drops following primary pars plana vitrectomy for retinal detachment.
Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases
To investigate the incidence of cystoid macular edema in eyes with primary rhegmatogenous retinal detachment successfully treated with vitrectomy with gas tamponade, and to evaluate the clinical variables associated with its development.
silicone oil tamponade removal after previous injection of complicated retinal detachment can be achieved with active suction followed by triple air-fluid exchange or prolonged lavage of the vitreous chamber to remove emulsification. Purpose of the study is to compare the amount of silicone oil emulsification droplets within the lavage fluid in case of air exchange and simple lavage to compare which technique removed the highest percentage of emulsion. This is achieved by comparing consecutive samples of lavage fluid
This is a randomized controlled trial comparing displacement of macula and the rapidity of reattachment of macula between two different positioning techniques after pneumatic retinopexy : Direct technique (patient is positioned so that the bubble is immediately placed directly over the retina break) and Steamroller technique (patient is initially positioned face down for 4-6 hours and subsequently changes their head position so that the bubble is then placed directly over the retina break).
The aim of the protocol is to compare the ocular outcomes after spontaneous vitreous hemorrhage treated with an early vitrectomy versus ultrasound monitoring with late vitrectomy. The hypothesis is that an early vitrectomy could decrease the rate of retinal detachment occurring after a spontaneous vitreous hemorrhage.
