Other Clinical Trial - Pneumatic Retinopexy Versus Vitrectomy for Retinal

Status Recruiting

Clinical Trial Summary

Objective: To compare outcomes of retinal detachment repair following pneumatic retinopexy (PnR) versus pars plana vitrectomy in terms of anatomical success, functional success and patient quality of life in patients with extended criteria.

Methods: A prospective, randomized, controlled trial will be conducted with 178 patients presenting at St. Michael's Hospital with primary retinal detachment (RD). Inclusion criteria include: a single or multiple retinal tears in detached retina between 7 and 5 o'clock being of any size and any distance apart from each other, including giant retinal tears with inferior aspect above 5 and 7 o'clock, RD with no identifiable tear but where suspected tear is between 7 and 5 o'clock, retinoschisis with RD if tears are located between 7 and 5 o'clock, mild proliferative vitreoretinopathy, none or mild vitreous hemorrhage. Patients will be excluded if there is a small retinal tear or multiple tears less than 30o apart between 8 and 4 o'clock in detached retina, retinal tear in detached retina between 5 and 7 o'clock, <18 years old, inability to read English, mental incapacity, previous history of RD, scleral buckle or vitrectomy in index eye, inability to maintain appropriate head posture at post-operative period and inability to visualize peripheral retinal due to media opacity. Patients will be randomly allocated into two groups: PnR + cryotherapy/laser or vitrectomy + cryotherapy/laser and the intervention will take place within 24 hours and 72 hours for attached and detached macula status, respectively. Patients will undergo a complete ophthalmological examination, including visual acuity and fundus assessment at baseline and at 3, 6 and 12 months after surgery. Visual acuity will also be measured at 1, 7 and 30 days after surgery. Global health related quality of life will be evaluated with the SF-36v2 questionnaire at baseline, 1 month, 1 and 2 years after intervention, while the VFG25 questionnaire will be applied at 3, 6, 12 and 24 months after surgery to measure vision related quality of life.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
