Pneumatic Retinopexy for Primary Rhegmatogenous Retinal Detachment: To Steamroll or Not

Rhegmatogenous Retinal Detachment Clinical Trial

Official title:
Pneumatic Retinopexy for Primary Rhegmatogenous Retinal Detachment: To Steamroll or Not

Clinical Trial Summary

This is a randomized controlled trial comparing displacement of macula and the rapidity of reattachment of macula between two different positioning techniques after pneumatic retinopexy : Direct technique (patient is positioned so that the bubble is immediately placed directly over the retina break) and Steamroller technique (patient is initially positioned face down for 4-6 hours and subsequently changes their head position so that the bubble is then placed directly over the retina break).

Clinical Trial Description

Pneumatic retinopexy (PR) is an established treatment for rhegmatogenous retinal detachment (RRD). In our centre, PR is the most commonly performed procedure for primary RRD repair with a high retinal reattachment success rate. In this procedure, patients are required to position according to the site of pathology following injection of an intravitreal gas bubble. Some practitioners position the patient so that the gas bubble is immediately apposed directly against the retinal break (direct technique). Others favour the steamroller technique whereby the patient is initially positioned face down, then after 4-6 hours, the position is changed sequentially so that the bubble is rolled over the retina towards the break responsible for the detachment (steamroller technique). Variable visual acuity (VA) outcomes and metamorphopsia are common post-procedure complaints despite successful RRD repair with PR. It has been suggested that variability in functional outcomes may be associated with the timing and ease of reattachment of macula. The purpose of this prospective study is to evaluate whether the steamroller technique is superior to the direct technique in faster reattachment of macula with less macula displacement. ;
