Self-indentation During Chandelier-assisted Peripheral Vitrectomy Under Air for Primary Retinal Detachment



To report the incidence of iatrogenic retinal breaks in eyes for whom self-indentation during chandelier-assisted peripheral vitrectomy under air, for primary retinal detachment, had been performed, compared to eyes for whom a non-indentation chandelier-assisted peripheral vitrectomy under air had been performed.


Retrospective cohort study. One hundred and thirty eyes with primary rhegmatogenous retinal detachment were identified. All the patients had undergone a chandelier-assisted peripheral vitrectomy under air. Self-indentation had been used in 68 eyes (study group) (Indentation group), while non-indentation had been used in 62 eyes (comparison group) (Non-indentation group). Outcome variables included trimming-induced retinal breaks, other iatrogenic retinal breaks (whether during posterior vitreous detachment or sclerotomy-related), redetachment rate, and final LogMAR BCVA.


The number of eyes with trimming-induced retinal breaks was statistically less in the indentation group than in non-indentation group (0/68 and 3/62 eyes, zero % and 4.8%, respectively). Number of trimming-induced retinal breaks was zero with indentation, and four with non-indentation. Other iatrogenic retinal breaks occurred in 1 eye with indentation (1/68), and in 3 eyes with non-indentation (3/62). Redetachment was observed in 1 eye with indentation (1/68) and in 3 eyes without indentation (3/62). There was no statistically significant difference in LogMAR BCVA between both groups.


Self-indentation during chandelier-assisted peripheral vitrectomy under air enables complete trimming of the vitreous base without causing iatrogenic retinal breaks, and allows for a higher retinal reattachment rate.
