Effects of Internal Limiting Membrane Peeling on Visual Function in Epiretinal Membrane Surgery...
Retinal DiseaseEpiretinal MembraneThe patients who are diagnosed with idiopathic epiretinal membrane and scheduled to undergo epiretinal membrane removal will be treated with conventional vitrectomy and the epiretinal membrane will be removed. After removal of the epiretinal membrane, indocyanine green staining will be used to determine the internal limiting membrane (ILM) peeled off with the epiretinal membrane. (Group 1: spontaneous ILM peeling) If it is confirmed that the internal limiting membrane is not peeled together, the investigators determine whether the active Internal limiting membrane peeling is performed by 1:1 randomization immediately during surgery. (Group 2: Active ILM peeling, Group 3: no ILM peeling) The outcomes of the three groups will be compared.
Role of Nepafenac in Reducing Macular Volume After Epiretinal Membrane Surgery
Epiretinal MembraneThe purpose of this study is to compare the macular volume of patients treated with a 3-month course of topical Nepafenac (0.1% solution) to patients treated with a placebo course following epiretinal membrane surgery.
Fourier Transformed Infrared Spectroscopy in Macular Surgery
Epiretinal MembraneMacular HoleEpiretinal membranes (ERM) are disorders leading to vision loss and metamorphopsia. Vitrectomy with membrane peeling has developed to be the gold-standard in treatment of ERM. ERM can be well visualized with spectral domain optical coherence tomography (SD-OCT). The aim of the study is to examine ERM and internal limiting membranes (ILM) exzised during routine macular surgery with fourier transformed infrared spectroscopy (FTIR) and compare results to optic coherence tomography (OCT) findings.
Intraoperative Analysis of the Central Retina in ERF
Epiretinal MembraneMacular PuckerChanges in the retinal anatomy that occur in epiretinal fibrosis have not been sufficiently studied. It is possible that epiretinal fibrosis leads not only to traction dislocation of the macula, but also to ILM anatomical disorders.
Brilliant Blue Versus Indocyanine Green
Macular PuckerMacular Hole1 moreA study of non-inferiority design comparing brilliant blue and indocyanine green as intraoperative dye in macular pucker and macular hole.
Retinal Layers and Visual Rehabilitation After Epiretinal Membrane Removal
Epiretinal MembraneThe purpose of this study is to evaluate the changes in visual acuity, metamorphopsia, and thickness of retinal layers after epiretinal membrane removal and to investigate factors associated with visual function.
UHR-OCT and HD-OCT for Preretinal Membranes: ICG Versus Membrane Blue
Retinal DiseasesUsing the UHR-OCT and HD-OCT to evaluate early postoperative changes in patients with diagnosis preretinal membrane after successfully performed pars-plana vitrectomy and membrane peeling with two different types of dyes.
Comparative Study of Sharkskin Versus Grieshaber Forceps During ILM Peeling
Epiretinal MembraneMacular HolesThe purpose of this study is to compare the performance and anatomic outcomes of the Sharkskin internal limiting membrane (ILM) forceps and the Grieshaber ILM forceps in macular surgery. Peeling of the ILM is a difficult aspect of vitreoretinal surgery and often daunting task from a vitreoretinal fellow's perspective. The hypothesis is that the newer Sharkskin forceps have a larger platform and micro-abrasions along the forcep surface to increase grasping ability and potentially limit trauma to the retina surface compared to the Grieshaber forceps. This project may also serve as an education tool for fellows learning the basics of ILM peeling.
Pharmakokinetik of Caffeine in Epiretinal Membranes After Oral Intake: a Pilot Study
Epiretinal MembraneCaffeine concentrations in the vitreous Body and exzised epiretinal membranes are measured by gas-chromatography/mass spectrometry.
Combined 25-gauge Vitrectomy and Cataract Surgery With Toric Intraocular Lens With Idiopathic Epiretinal...
CataractEpiretinal Membrane1 moreToric intraocular lens (IOL) is now widely used for the cataract surgery with preoperative corneal astigmatism. Symptomatic epiretinal membrane (ERM) is often treated with 25-gauge transconjunctival sutureless vitrectomy, resulting in good visual recovery. So far, however, limited information is available on the the stability of axis rotation, astigmatism correction, and improvement in uncorrected distance visual acuity, using astigmatism-correcting IOL in a 25-gauge transconjunctival sutureless vitrectomy combined with cataract surgery. In the current study, eyes with a preoperative corneal cylinder of more than 0.75 diopter had a triple procedure for idiopathic ERM using a toric IOL. Outcome measures will be the amount of IOL axis rotation, uncorrected visual acuity, corrected distance visual acuity, and corneal and refractive astigmatism up to 6 months postoperatively. We are expecting to show that postoperative IOL axis stability is similar to that reported for cataract surgery alone in vitrectomy (triple procedure) for idiopathic ERM with a toric IOL.
