About this trial

To demonstrate that intraoperative use of subtenon triamcinolone acetonide at the time of surgery without postoperative eye drops is non-inferior to the regimen of postoperative eye drops following primary pars plana vitrectomy for retinal detachment.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Disqualifiers

Need for concomitant lensectomy or cataract surgery

Pars plana vitrectomy taking place more than seven days after the initial diagnosis

History of any prior vitreoretinal surgery (excluding laser surgery) in surgical eye

History of previous retinal detachment in surgical eye
