Exclusion criteria: vitrectomized eyes
former intravitreal anti-VEGF or steroid injections
former focal or panretinal laser coagulation
former retinal kryocoagulation

Age minimum: 18 Years
Age maximum: 100 Years
Gender: All
Health Condition(s) or Problem(s) studied
Retinal detachment with retinal break

H35.3
H33.0
H43.3
H35.3
H43.3
H33.0
Degeneration of macula and posterior pole
Other vitreous opacities
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).
