Key inclusion & exclusion criteria
|
Inclusion criteria: H35.3 Degeneration of the macula and posterior pole H33.0 rhegmatogenous retinal detachment H43.3 vitreous floater patients are included who will receive a pars plana vitrectomy routinely with following diseases: epiretinal membrane, macular hole, retinal detachment, diabetic macular edema, wet age-related macular degeneration, retinal vein occlusion
Exclusion criteria: vitrectomized eyes former intravitreal anti-VEGF or steroid injections former focal or panretinal laser coagulation former retinal kryocoagulation former uveitis former buckle surgery

Intervention(s)
|
Group 1: retinal diseases inclusing: epiretinal membrane macular hole retinal detachment diabetic macular edema wet age-related macular degeneration retinal vein occlusion. Patients enrolled into this study will receive a pars plana vitrectomy. Vitreous specimen will be collected at the beginning of the procedure. Vitreous taps will be analyzed in regard to opsin concentrations in different diseases of the retina and the vitreoretinal border. Group 2: vitreous floater as control Group (all retinal diseases excluded)
|
Primary Outcome(s)
|
Intravitreal opsin concentrations in different alterations of the vitreomacular Interface as measured with cytometric bead assay (CBA). Analysis will be performed within 6 months after sampling vitreous specimen. Comparison of intravitreal opsin concentrations among the different retinal diseases and between the retinal diseases and the controll Group (vitreous floater without any acommpanying retinal disease).
