Study design	Non-randomised prospective observational study
Primary study design	Observational
Secondary study design	Case-control study
Study setting(s)	Other
Study type	Treatment
Scientific title	Macula off rhegmatogenous retinal detachment and its functional recovery
Study objectives	Optimum timing of surgery for macula off rhegmatogenous retinal detachment can be determined in more detail by taking both duration and height of macular detachment into account.
Ethics approval(s)	Approval received from the local ethics committee (Medisch Ethische Toetsingscommissie Universitair Medisch Centrum Groningen [METc UMCG]) on the 11th July 2006 (ref: 12551).
Health condition(s) or problem(s) studied	Rhegmatogenous retinal detachment
Intervention	Vitreoretinal surgery according to current practice guidelines.
Intervention type	Other
Primary outcome measure	1. Visual acuity in relation to duration and height of macular detachment 2. Individual parameters relating to visual function, subjective contentness and morphology of the macula in relation to each other, duration and height of macular detachment Primary study group: Pre-operative and postoperative at one, three, six and 12 months. Secondary study group: Pre-operative and one year after the latest vitreoretinal surgery.
Secondary outcome measures	1. Correlation between height macular detachment measured by ultrasonography and by optical coherence tomography 2. Relationship between subjective contentness in the primary and secondary study groups
Overall study start date	01/02/2007
Completion date	31/12/2011
