Retinal Detachment Treatment—Pneumatic Retinopexy

Two procedures treat retinal detachment: pars plana vitrectomy (PPV; removal of vitreous from the eye) and pneumatic retinopexy (PnR; gas injection into the eye to exert gentle pressure to reattach the retina). • Some outcomes following PnR may be superior to PPV for managing rhegmatogenous retinal detachment, based on randomized clinical trial findings. • This animation video illustrates a possible mechanism for the difference in visual acuity outcomes between the 2 procedures based on observations of photoreceptor integrity on spectral-domain optical coherence tomography (OCT) after 12 months. • PnR involves injection of a gas bubble into the vitreous cavity that exerts minimum buoyant forces on the retina, potentially allowing the retinal pigment epithelium (RPE) pump to reabsorb the subretinal fluid and the photoreceptors to interdigitate [00:10]. The photoreceptor layer re-apposition to the RPE may be more optimal, with less photoreceptor cell death, better visual acuity outcomes, and no visible discontinuities of the ellipsoid zone (EZ) and external limiting membrane (ELM) on OCT imaging compared with PPV repair. • Click • Retinal Detachment Treatment—Pars Pla... for a parallel video illustration of retinal reattachment following PPV repair and https://ja.ma/3emjlYh for full article details.
