Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Does the use of an additional anti inflammatory agent (ozurdex) given at the time of surgery in patients with established PVR (scar tissue on the retina)result in an improved surgical outcome at 6 months after the surgery?; Secondary Objective: Does the use of an additional anti inflammatory agent (ozurdex) given at the time of surgery in patients with established PVR (scar tissue on the retina)have a positive effect on the following: 1. Visual acuity 6 and 12 months after initial surgery (number of letters read on a standardised vision chart) 2. macula oedema and thickness (the presence of abnormal waterlogging and therefore increased thickness of the most sensitive part of the retina) 3. the development of overt PVR recurrence (whether the scar tissue returns more floridly after surgery 4. complete retinal reattachment (the ability to re attach the entire retina as in some cases this is not possible) 5. stable posterior (post equatorial) retinal reattachment (the ability to reattach the central part of the retina,as in some cases the entire retina cannot be reattached) 6. tractional retinal detachment (the presence of any remaining scar tissue pulling the retina off after surge ;Primary end point(s): Stable retinal reattachment with removal of silicone oil without further vitreoretinal surgical intervention at 6 months;Timepoint(s) of evaluation of this end point: 6 months after initial surgery for proliferative vitreoretinopathy | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: All at 12 months post initial surgical intervention for PVR (with the exception of visual acuity, which will be measured at 6 and 12 months); Secondary end point(s): i) visual acuity (median and ETDRS of 55 letters or better) at 6 and 12 months post op ii) macula oedema and thickness (OCT analysis) iii) development of overt PVR recurrence iv) complete retinal reattachment v) stable posterior (post equatorial) retinal reattachment vi) tractional retinal detachment vii) hypotony/raised IOP viii) macula pucker/epiretinal membrane ix) cataract x) quality of life assessment | — |
