Title	Amniotic membrane plugging for posterior retracted retinal breaks and breaks asssociated with chorioretinal atrophy: A silicone oil–sparing technique

Purpose	To evaluate the mid-term safety and efficacy of amniotic membrane plugs as a surgical technique for treating posterior retinal breaks, either retracted or associated with chorioretinal atrophy, in tractional retinal detachment with the aim of avoiding silicone oil tamponade
Methods	This study included patients with rhegmatogenous retinal detachment associated with at least grade C proliferative vitreoretinopathy, or with tractional retinal detachment, in whom posterior retinal breaks, either retracted or associated with chorioretinal atrophy were sealed using amniotic membrane plugs with gas tamponade. Minimum follow-up was 12 months. The main outcome was retinal detachment recurrence. Measures included visual acuity, optical coherence tomography, fundus photography, intraocular pressure, and re-detachment rate.
Results	Fifteen eyes of 15 patients were included. Mean best-corrected visual acuity at 12 months postoperatively was 0.71 logMAR, compared with 2.15 preoperatively. Fundus photography and optical coherence tomography showed that the plugs remained in place at 1, 3, 6, and 12 months, with no dislocation. Glial tissue regeneration was observed, without restoration of the original retinal layers. Only one eye (6.67%) did not meet the primary outcome, with recurrent retinal detachment occurring 2 months after surgery, requiring silicone oil tamponade. No elevation of intraocular pressure or signs of inflammation were recorded
Conclusion	With a success rate of 93.33% (14/15 eyes) at 12 months, amniotic membrane plugging appears to be a safe and effective technique to avoid silicone oil tamponade in posterior retinal breaks, whether retracted or associated with chorioretinal atrophy, potentially overcoming some limitations of laser retinopexy.
