Estimated Enrollment: 20
Study Start Date: September 2005
Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: ppVE, MP, ICG
    surgery with ILM staining
    Procedure: ppVE, MP, MB
    Surgery with ERM staining
Detailed Description:

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.
