Filter by:In the current study, the investigators described the results of a randomized, comparative clinical trial that was conducted to study the impact of the size of internal limiting membrane (ILM) inverted flap on rate and timing of idiopathic macular hole closure.
Macular hole is a full thickness retinal defect in the very centre of the retina that gives the sharpest vision. The condition causes a substantial deterioration of visual acuity, and operative measures are necessary in order to close the defect and improve the visual function. A macular hole has varying degrees of retinal oedema surrounding the hole edges. The oedema is maintained by continuous of liquid into the tissue and effectively prevents spontaneous closure. For that reason it is essential for macular hole closure that the macula has minimal contact with intraocular fluid in the very early postoperative phase. This is why the treatment included a long-lasting intraocular gas tamponade and typically, one week of face-down positioning (FDP) after surgery.Our aim is to investigate the impact of diurnal, orthostatic, and gravitational variations on macular hole morphology before and after surgery. The participants will be examinated with optical coherence tomography 8-10 am, 1 pm, and 3 pm. Between 8 am and 1 pm ,the patient is encouraged to an upright position. After the 1 pm examination, the patient will be positioned flat on the side of the eye with macular hole until the 3 pm examination. The surgery will be performed before 10 am. Postoperatively a randomization to face down positioning or no positioning until 3 am. Optical coherence tomography images through gas tamponade is made at 3 am.
The purpose of this study is to investigate displacement of the retina after idiopathic macular hole surgery with different internal limiting membrane peeling patterns.
The purpose of this study is to evaluate the effects of a structured exercise program on musculoskeletal pain of patients in face-down posture after retinal surgery.
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 describe the technique and outcomes of using either inverted or free internal limiting membrane flap in the management of retinal detachment due to paracentral retinal breaks.
