Suprachoroidal Visco-buckling for the Treatment of Rhegmatogenous Retinal Detachment

Inclusion Criteria: Patients requiring pars plana vitrectomy for the treatment of primary rhegmatogenousretinal detachment (RD) caused by a single break, or multiple breaks within one clock hour.The final determination of qualifying breaks is made at the time of surgery following 360-degree, internal, indented search using a wide-angle viewing system.

Exclusion Criteria:

• Hypersensitivity to hyaluronate or. HEALON5® PRO OVD
• Participation in another interventional study within 8 weeks of enrolment or plannedto occur during this study.
• Bleeding disorders or the use of anticoagulants (such as warfarin, rivaroxaban) ordual anti-platelet drugs such as aspirin with clopidogrel. Monotherapy with low dose (≤100 mg) aspirin is permitted, and if clinically appropriate this should be stoppedprior to surgery and recommenced only after satisfactory day 1 post-operative review.
• Unwilling, unable, or unlikely to return for scheduled follow-up for the duration ofthe trial.
• Any other condition that, in the opinion of the investigator, would prevent theparticipant from granting informed consent or complying with the protocol, such asdementia, mental illness, or serious systemic medical disease. Study eye:
• Presence of proliferative vitreoretinopathy (PVR) or any tractional RD
• Previous vitreoretinal surgery, open-globe injury or endophthalmitis
• Aphakia
• Previous or current congenital cataract
• Previous or current suprachoroidal haemorrhage
• Congenital or acquired ocular, orbital or periocular abnormality that, in the opinionof the attending vitreoretinal surgeon, would preclude the safe delivery of Healon 5into the suprachoroidal space (detail the specific reason for exclusion in the sourcedocuments)
• Presence of other ocular co-morbidity that, in the opinion of the investigator, islikely to prevent an accurate assessment of retinal attachment
• Current intraocular inflammation other than mild cellular activity thought to besecondary to RD
• Current ocular or periocular infection other than blepharitis
