Active clinical trials for "Epiretinal Membrane"

The purpose of this study is to compare the newly released Spectral OCT/SLO (OTI, Toronto, Canada) with the Zeiss Stratus OCT (Carl-Zeiss Meditec, Dublin, CA) with regards to the quality of the images obtained as well as the ease of use.

This study examines whether the presence of an epiretinal membrane affects the time to resolution, requirement for non-topical treatment, and outcome of pseudophakic cystoid macular oedema.

To report cases who had received previous fovea-sparing internal limiting peeling membrane and developed secondary fovea epiretinal membrane contraction

Retrospective interventional case series study reporting preoperative clinical and anatomical factors associated with visual recovery 1 year after combined cataract and idiopathic epiretinal membrane surgery. Age, duration of symptoms, and preoperative best corrected visual acuity appeared to be reliable prognostic factors. Combining these factors with analysis of the photoreceptors' inner and outer segments junction in spectral-domain optical coherence tomography provides a predictive score to estimate individual chances of good visual recovery

To compare possible toxicities of membrane blue and infracyanine green in vivo by macular function and peripheral visual field.

Comparison between intravitreous glucose rate and macular thinning measured by Ocular Coherence Tomography (OCT) at 3 months post vitrectomy for retinal detachment or epimacular membrane. Hypothesis : Association between post-operative macular thickness and intravitreous glucose rate

The purpose of this study was to investigate the expression of selected genes both in epiretinal membranes (ERMs) and peripheral blood mononuclear cells (PBMCs) from patients with primary and secondary epiretinal membranes in proliferative diabetic retinopathy. Possible correlations between messenger ribonucleic acid (mRNA) levels of these genes were also identified.

ILM and ERM are routinely excised during surgery, as part of the surgical technique, and cultivation of hyalocytes will be performed ex vivo after surgery.

In our study , the investigators will use the microscope with OCT ( Lumera with RESCAN OCT ) coupled to assess the extent , depth and change of retinal architecture in the perioperative period . Thus , they will evaluate what the optimal maneuvers of dissection of macular membranes to obtain a more satisfactory result of the rearrangement in the retinal layers . Furthermore , the use of OCT perioperative may dispense with the use of dyes , decreasing the concentration used or reduce the exposure time. Thus, they can get the potential decrease in retinal toxicity may be generated by them.

To evulate changes in MfERG, VF and OCT after viterctomy associated with ILM peeling.
