Study information

Primary study designObservational
Study designNon-randomised prospective observational study
Secondary study designCase-control study
Scientific titleMacula off rhegmatogenous retinal detachment and its functional recovery
Study objectivesOptimum 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) studiedRhegmatogenous retinal detachment
InterventionVitreoretinal surgery according to current practice guidelines.
Intervention typeOther
Primary outcome measure(s)

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.

Key secondary outcome measure(s)

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

Completion date31/12/2011
