THE MINI-STEAMROLL: An Abbreviated Variation of the Steamroller Maneuver After Pneumatic Retinopexy for Rhegmatogenous Retinal Detachment.

Abstract

Purpose: To describe a novel positioning maneuver for patients with rhegmatogenous retinal detachment after pneumatic retinopexy (PnR).

Methods: Single-center prospective case series of primary rhegmatogenous retinal detachments referred to St. Michael's Hospital, Toronto, Canada, between 2021 and 2023. All patients underwent PnR. Baseline ultra-widefield fundus imaging and repeat imaging 10 minutes after the gas injection was performed. After PnR, patients were instructed to perform the mini-steamroll maneuver, which consists of a face-down position for 10 minutes followed by positioning to the retinal break. The reduction of subretinal fluid volume after the initial face-down position was evaluated with clinical examination and ultra-widefield imaging.

Results: Six patients who presented with primary bullous rhegmatogenous retinal detachment and a sizable superior break were enrolled. The mini-steamroll maneuver resulted in a rapid and significant reduction of subretinal fluid in all patients with bullous rhegmatogenous retinal detachment and large superior breaks, allowing subretinal fluid to be expressed into the vitreous cavity with 10 minutes of face-down positioning. One patient required a sequential PnR. Primary retinal reattachment was achieved in all cases. This approach was well-tolerated by patients.

Conclusion: This case series demonstrates that the mini-steamroll maneuver may be a suitable alternative for patient positioning after PnR in certain cases. The mini-steamroll is a simpler positioning regimen with the potential benefits of direct-to-break and full steamroller maneuver.
