Change in Foveal Avascular Zone After Removal of Epiretinal Membrane and Internal Limiting Membrane...

Epiretinal Membrane

Fovea is characterized by its vessel-free zone, called foveal avascular zone and it can be visualized by fluorescein angiography. Removal of epiretinal membrane and internal limiting membrane is frequently performed procedure and we suspected that these procedures may affect integrity of foveal avascular zone. The purpose of the present study is to evaluate the change of foveal avascular zone after removal of epiretinal membrane and internal limiting membrane

PIONEER: Intraoperative and Perioperative OCT Study

Retinal DetachmentEpiretinal Membrane2 more

OCT provides high-resolution information regarding the anatomic structure of the tissues of the eye in a 2-dimensional and 3-dimensional view. Much of this information is not able to be recognized by a clinician. Utilizing this information during surgery will allow for ophthalmic surgeons to better understand how surgical procedures impact the anatomic structure of the eye.

Reading Analysis in Ophthalmologic Patients

Diabetic MaculopathyAge Related Macular Degeneration2 more

Investigation of the reading parameters and fixation behavior in patients with different ocular diseases (age-related macular degeneration, glaucoma, diabetic maculopathy, epiretinal membrane) and healthy subjects. In addition, fixation analysis and retinal sensitivity measurements will be done with a microperimeter in each subject.

Applicability of the Acai Fruit (Euterpe Oleracea) Dye for Chromovitrectomy in Humans

Epiretinal MembraneMacular Hole1 more

Our research group tested the toxicity of different dye concentrations extracted from the acai fruit using a rabbit model. The dye extracted from the acai fruit in concentrations of 10% and 25% was found to be safe for vitreoretinal surgery. This initial research represented the landmark research for testing this alternative vital dye in a clinical research in humans. The aim of the present clinical trial in humans will be to test the applicability of the acai dye in the identification of the posterior hyaloid and ILM during vitreoretinal surgery in humans.

Inflammasomes in Cell Death in FTMH, ERM, and RRD

Retinal DetachmentFull Thickness Macular Hole1 more

Prospective study evaluating the role of inflammasomes in cell death in retinal detachment, full thickness macular hole, and epiretinal membrane. The investigators are collecting vitreous and subretinal fluid samples from patients with these conditions and evaluating activity of the inflammasome pathway with established assays.

Mid-term Evaluation of Metamorphopsia in Epiretinal Membrane Surgery

Epiretinal MembraneCataract Senile

This study evaluates the safety and efficacy simultaneous, trans-conjunctival, 25-Gauge vitrectomy and phacoemulsification with intraocular lens implant in patients with metamorphopsia and visual impairment due to idiopathic epiretinal membrane and cataract. All 30 patients recruited underwent complete ocular examination, visual acuity measurement with ETDRS, metamorphopsia assessment with M-Charts and Metamorphometry® and foveal thickness evaluation by sd-OCT preoperatively, at 30, 90, 180 days postoperatively.

Refractive Changes Following Vitrectomy

Retinal DetachmentRefractive Errors2 more

We aimed o compare the refractive changes associated with pars plana vitrectomy with or without intraocular gas tamponade in pseudophakic eyes. This retrospective study included pseudophakic patients with Nd:YAG laser posterior capsulotomy who underwent 23G PPV between February 2015 and March 2019. Group 1 consisted of patients with regmatogenous RD who underwent PPV and 12% perflouropropane (C3F8) gas tamponade whereas Group 2 consisted of patients who underwent PPV for epiretinal membrane or vitreous hemorrhage (VH). No tamponade was used in Group 2. Minimum follow-up was 12 months.

Outcomes Based on the Pre-operative Integrity of IS/OS Junction in Idiopathic Epimacular Membrane...

Epimacular Membrane

The aim of this study is to evaluate whether the pre-operative integrity or not of the inner segment (IS) and outer segment (OS) photoreceptoral junction may influence the post-operative visual acuity, the macular morphology (assessed by Spectral Domain-Optical Coherence Tomography (SD-OCT)) and function (evaluated by Multifocal Electroretinogram -mfERG) in patients with idiopathic epimacular membrane (EMM) followed-up for 6-month. In this observational prospective study, EMM patients are enrolled. They are divided into 2 groups in relationship to the pre-operative integrity of the SD-OCT IS/OS junction: the group with an intact IS/OS junction (EMM-I Group) and the group with a disrupted IS/OS junction (EMM-D Group). For each enrolled patient, visual acuity (VA), mfERG and SD-OCT were assessed at baseline (pre-operative) and after 1, 3 and 6 months of follow-up after surgical treatment for EMM (pars plana vitrectomy with EMM removal and internal limiting membrane peeling).
