An interventional study of ppVE, MP, ICG and ppVE, MP, MB in Retinal Diseases, sponsored by The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery. Completed at 1 site in Austria. Open to participants aged 18 Years to 85 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2008-09-23.
Sponsored by The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery · Not applicable, Interventional, and Diagnostic
Using 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.
Surgical procedures performed are pars-plana vitrectomy and membrane peeling with or without cataract extraction and IOL implantation. The type of the dyes is randomized. The study is designed to include a total of tweny cases (10 cases with ICG and 10 cases with Membrane blue)
Main outcome measures are:
UHR-OCT, HD-OCT distance and near visual acuity and contrast sensitivity amsler grid secondary outcome measures are: OCT Stratus 3000 and visual field. Clinical examinations: preoperative, and follow-up examinations after 1 week, 1 months, 3 months, 6 months and 12 months.
817 studies on the registry are indexed under Retinal Diseases; 104 are open to participants now.
This study's planned enrollment of 20 is below the median of 60 across 502 interventional studies indexed under Retinal Diseases.
