Pneumatic retinopexy

PURPOSE: To study the behaviour of expansile intravitreal gases and air used in treating rhegmatogenous retinal detachment. METHODS: A validated mathematical model of gas expansion and absorption in human eyes was used to simulate the effect of varying volumes of pure air, SF6, C2F6 and C3F8 injected into the vitreous cavity. Variation in axial length was accounted for by using three different vitreous cavity volumes to represent hypermetropic, emmetropic and myopic eyes...

PURPOSE: To compare the outcomes of primary uncomplicated rhegmatogenous retinal detachment (RRD) repair using pars plana vitrectomy (PPV), scleral buckling (SB), or combined scleral buckling with vitrectomy (SB/PPV). PATIENTS AND METHODS: Single-institution, retrospective, observational study of 179 patients with primary RRD managed at a large academic hospital system. We excluded patients with less than 6 months of follow-up, previous vitrectomy or buckle, giant retinal tears, aphakia, recurrent forms of RRD, or extensive proliferative vitreoretinopathy (Grade C or worse) documented on exam or requiring membrane peel...

PURPOSE: To determine the treatment patterns and outcomes of pediatric retinal detachments (RDs) associated with hereditary vitreoretinopathies. DESIGN: Retrospective cohort analysis using IRIS® Registry (Intelligent Research in Sight) database. PARTICIPANTS: Patients < 18 years old with a rhegmatogenous RD and a systemic disorder associated with vitreoretinal degeneration (e.g., Stickler syndrome) or other malformation of the vitreous from 2013-2019...

The clinical efficacy of pneumatic retinopexy (PR) using intravitreal pure air injection and laser photocoagulation for rhegmatogenous retinal detachment (RRD) remains unknown. Thirty-nine consecutive patients with RRD (39 eyes) were included in this prospective case series. All patients underwent two-step PR surgery containing pure air intravitreal injection and laser photocoagulation retinopexy during hospitalization. The main outcomes were best-corrected visual acuity (BCVA) and primary anatomic success rates after PR treatment...

PURPOSE: To compare foveal avascular zone (FAZ) geometric indices using optical coherence tomography angiography (OCTA) in pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). FAZ morphology was assessed as a possible imaging feature of retinal displacement. METHODS: This ALIGN post hoc analysis included primary fovea-off RRDs that underwent successful PnR or PPV, and performed OCTA, and fundus autofluorescence at (FAF) 3 months postoperatively at St...

INTRODUCTION: Pneumatic retinopexy (PnR) was proposed as an alternative to pars plana vitrectomy (PPV) in certain circumstances. PnR is an outpatient procedure and more cost-effective. However, its benefits should be judged alongside its success rate and adverse events. Herein, we compare the efficacy and safety of PnR and PPV for rhegmatogenous retinal detachment (RRD) repair. METHODS: We searched the PubMed, Scopus, EMBASE, Web of Science, Cochrane, and Google Scholar databases...

OBJECTIVE OR PURPOSE: Primary proliferative vitreoretinopathy (PVR) is established as an important cause of the failed repair of a fresh retinal detachment (RD) and the consequent need for secondary repair. However, the burden of multiple re-operations beyond the initial failure has not been studied in detail. We aimed to determine the association between primary PVR and the occurrence of tertiary, quaternary, and quinary RD repairs, using a nationwide database. DESIGN: Retrospective cohort study of insurance claims...

Rhegmatogenous retinal detachment (RRD) is a serious surgical condition with significant ocular morbidity if not managed properly. Once untreatable, approaches to the repair of RRD have greatly evolved over the years, leading to outstanding primary surgical success rates. The management of RRD is often a topic of great debate. Scleral buckling, vitrectomy and pneumatic retinopexy have been used successfully for the treatment of RRD. Several factors may affect surgical success and dictate a surgeon's preference for the technique employed...

PURPOSE: Outcomes of pneumatic retinopexy (PnR) using surgical microscope, wide-angle viewing system, and chandelier endoilluminator (microscope-assisted pneumatic retinopexy) for primary rhegmatogenous retinal detachment (RRD). METHODS: Retrospective study. 43 consecutive eyes with RRD undergoing microscope-assisted PnR surgery (MAPR) were analysed. Inclusion criteria comprehend phakic eyes with single retinal break or a group of breaks in detached retina in the same quadrant above 8- and 4-o'clock meridians...

As part of a series of autobiographical case reports about physicians reporting on their own medical afflictions, a psychiatrist copes with a retinal detachment through an artistic collaboration with a medical student. The air bubble injected into the patient's eye shapeshifts during the six weeks of recovery and becomes the basis for a collaborative artistic project. The series of jointly created images becomes a source of comfort and solace for the patient and of developmental growth for the medical student becoming a physician...

The management of rhegmatogenous retinal detachment has rapidly evolved over recent decades. A range of surgical techniques exist, all of which can achieve retinal reattachment in most cases. In recent years there have also been vast technical advances in retinal imaging that have introduced novel ways of visualizing and studying the retinal macro and microstructural anatomy following retinal detachment repair. Recent clinical trial data demonstrates that functional and patient-reported outcomes of retinal reattachment differ with surgical technique, accompanied by differences in anatomic biomarkers of retinal recovery or 'integrity'...
