Effect of Type of Head Positioning on Retinal Displacement in Vitrectomy for Retinal Detachment (DIAMOND)
Retinal Detachment, Metamorphopsia
About this trial
This is an interventional prevention trial for Retinal Detachment
Eligibility Criteria
Inclusion Criteria:
- Age ≥ 18
- Diagnosis of primary rhegmatogenous retinal detachment needing pars plana vitrectomy with the detachment involving at least one of the temporal vascular arcades, which would allow retinal displacement to be detected on fundus autofluorescence photography
Exclusion Criteria:
- Rhegmatogenous retinal detachment with an attached macula
- Proliferative retinopathy grade C or worst
- Prior vitrectomy for retinal detachment. Patients having had pneumatic retinopexy that failed to completely reattach the retina and therefore now needing vitrectomy are allowed into the study
- History of preoperative binocular diplopia
- Tamponade with silicone oil instead of gas
- Inability to maintain post operation head positioning
- Mental incapacity

Arms of the Study
Arm 1
Arm 2
Active Comparator
Experimental
Conventional face down positioning
Supine positioning
Patients in third arm will be treated with the current standard of care, that is, they will be kept supine in the ophthalmic surgery chair after the completion of their surgery. They will then be taken to the recovery area where, once transferred to the care of the postoperative care unit staff, they will transition to face down positioning. They will maintain this positioning until their first day postoperative visit after which they will position according to the retinal breaks found during surgery.
Patients in the second arm will be kept supine after the completion of their surgery. They will then be taken to the recovery area where, once transferred to the care of the postoperative care unit staff, they will maintain supine positioning. They will maintain this positioning until their first day postoperative visit after which they will position according to the retinal breaks found during surgery.
