Description
Summary:Background Retrospective analysis of morphological and functional outcomes after pars-plana vitrectomy and Silicone-Oil (SO) endotamponade in acute postoperative endophthalmitis (APOE). Methods Minimum follow-up was 6 months. Every included patient received best-corrected visual acuity (BCVA) assessment, pre-operatively and at last follow-up. Spectralis OCT was used to investigate disorganization of inner (DRIL) and outer (DROL) retinal layers at 1, 3, 6 months and at last follow-up. OCT-A was performed to assess foveal avascular zone (FAZ) and vascular perfusion density (VPD) at 6 months and at last follow-up. Results Seventeen eyes were recruited. Postoperative findings: BCVA ≥ 20/40 (in 14 eyes); epiretinal membranes (13); hyperreflective epiretinal material soon after surgery in (6) SO-filled eyes; inner retinal layers atrophy (5); macular edema (2); DROL (4) with persistent EZ disruption at final visit (2); no significant difference between study and fellow eyes in central macular thickness, FAZ and VPD; VPD decreased in all cases with prominent disorganization of retinal architecture. Conclusion OCT changes after APOE can be persistent or completely/partially self-resolving and seems related to the outward progression path of the infection/inflammation from the vitreous cavity to the inner and outer retina, rather than to the surgery.
