Filter by:To undertake a prospective randomized clinical trial of vitrectomy and gas tamponade to treat macular hole, utilizing a small amount of undiluted C3F8 (perfluoropropane) versus a large amount of diluted C3F8 versus a small amount of undiluted SF6 (sulfur hexafluoride) versus a large amount of diluted SF6.
The aim of this study was to determine whether inverted ILM peeling technique could contribute to high reattachment and closure rates after vitrectomy in patients with myopic macular hole retinal detachment (MHRD) in comparison to no ILM peeling. This retrospective study will include 40 patients presenting by myopic macular hole retinal detachment. Exclusion criteria will include history of trauma, choroidal neovascularization, and the presence of a peripheral retinal break or proliferative vitreoretinopathy before the initial surgery. Subjects will be divided into 2 groups; Group 1 will include 20 patients that were treated by vitrectomy without ILM peeling and postoperative gas or silicone oil tamponade with or without cataract surgery. Group 2 will include 20 patients that were treated by vitrectomy with ILMflap technique and postoperative gas or silicone oil tamponade with or without cataract surgery.
This study will compare by swept-source optical coherence tomography (SS-OCT) the retinal morphology after inverted internal limiting membrane (I-ILM) flap vitreoretinal surgery for medium-to-large macular holes using infracyanine green (IFCG) vs brilliant blue G (BBG) dyeing. It is a single-center prospective, randomized study. One group of patients will undergo I-ILM vitrectomy with IFCG staining, the other vitrectomy with BBG staining. Postoperative twelve-month corrected distance visual acuity, macular hole closure rate, and SS-OCT parameters will be compared and statistically analyzed. The aim of the study is to verify if these parameters can be negatively affected by toxicity related to the use of one of the two dyes.
Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.
This is a prospective, interventional, consecutive case series conducted in Alexandria university. The aim of the study is to evaluate the therapeutic efficacy of human amniotic membrane in promoting closure of large macular holes.
To examine the relationship between morphological and functional results in eyes after vitrectomy due to the full thickness macular hole (FTMH).
Patients with macular hole <400µm will be randomized for ILM flap Transposition and ILM Peeling for surgical repair of macular holes
This is a prospective, multicenter, randomized non-inferiority trial, where the macular hole closure rate with intraocular air tamponade is compared to the closure rate with gas tamponade.The patients are randomized to receive either air or gas (26% SF6) as intraocular tamponade, just prior to the intraocular flushing of the tamponade during the vitrectomy procedure. Postoperatively, the patients adhere to the nonsupine regimen for three days, and the tennis ball technique is used during sleep to enhance patients' positioning compliance.
To present the clinical characteristics and rational treatment of macular hole (MH) after the diabetic vitrectomy (DV) in patients with proliferative diabetic retinopathy (PDR).
Full-thickness macular Hole associated with macular detachment is a one of the maculopathies of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling versus vitrectomy in a cohort of highly myopic eyes with this situation.
