“…However, Xiang et al, despite showing a diminished retinal thickness, did not find changes in the FAZ area or VD in both retinal plexuses [39]. Bayraktar et al showed changes in VD only in their macula-off RRD group [40]. Maqsood et al [41] observed no significant difference in the FAZ between macula-off RRD eyes and healthy eyes at 12 weeks after the intervention.…”

“…Most of the published studies that analyzed the vascular density after RD surgery reported a decrease of either superficial or deep vascular plexus. 3,8 Bayraktar, 3 in a cohort of 24 eyes with macula-off detachments, observed a reduction in both SCPvd and DCPvd associated with FAZ enlargement and a thinner CMT, as compared with the fellow eye after 3 months. Interestingly, none of these studies found an increased SCPvd after surgery as we did.…”

“…Optical coherence tomography angiography parameters demonstrated modifications of the capillary density in those cases. 2,3 Hypothesis have been made that these modifications may be because of hypoxia or local conditions during the SO tamponade period. 4 Dormegny et al 7 recently reported a microvascular remodeling after vitreoretinal surgery with SO tamponade, which was associated with the presence of macular cysts.…”

Purpose: To determine the long-term microvascular alterations associated with macular cystic changes after retinal detachment surgery with silicone oil tamponade.Methods: The results of two optical coherence tomography angiographies performed at 11 months and 38 months after silicone removal were retrospectively analyzed for 30 eyes. The data were compared between both measurements and between eyes with macular cysts (MC+) and without macular cysts (MC2). Two patterns of cysts were identified and compared: cysts exclusively involving the inner nuclear layer (INLc) and cysts present in all retinal layers.Results: At both end points, 20 eyes (67%) presented with macular cysts, 12 of them (40%) had INLc. At the first end point, vascular density of superficial capillary plexus was higher and superficial foveal avascular zone was smaller in MC+ eyes than in MC2 eyes (P = 0.04 and P = 0.017, respectively). At the second end point, vascular density of superficial capillary plexus significantly decreased in MC+ eyes as compared with the first end point (P , 0.001) and superficial foveal avascular zone enlarged (P , 0.001). Macular central thickness decreased between follow-ups only in eyes with INLc (P , 0.01). The final best-corrected visual acuity was better in eyes with INLc than in eyes with cysts present in all retinal layers (P , 0.01). There was no difference between the final best-corrected visual acuity in eyes with INLc and MC2 eyes.Conclusion: Macular cysts are a common finding long after silicon removal. Vascular remodeling seems characterized by an initial increase of the vascular density of superficial capillary plexus in eyes with cysts, which is followed by its progressive decrease. The INLc is the most common pattern of cysts. They are associated with a progressive decrease of the central macular thickness without visual impairment.

“…So far, OCTA based studies mainly evaluated the impact of SO filling, in which alterations of the microvasculature were present [ 6 , 14 , 15 ]. However, data on the impact of SO removal is limited, and studies on choroidal changes in this context do not exist as far as we know [ 16 , 17 ]. An OCTA study by Bayraktar et al evaluated the superficial and deep capillary plexus of the retina before and after SO removal and compared patients with attached and detached macula before vitreoretinal surgery [ 17 ].…”

An OCTA study by Bayraktar et al evaluated the superficial and deep capillary plexus of the retina before and after SO removal and compared patients with attached and detached macula before vitreoretinal surgery [ 17 ]. Removal of SO resulted in permanent morphological and vascular alterations as compared with the healthy fellow eyes, which did not disappear after SO removal in the group of eyes with macula-off retinal detachment.…”

Impact of Silicone Oil Removal on Macular Perfusion

(1) Background: Silicone oil (SO) can be used as an endotamponade during vitreoretinal surgery for retinal detachment. There is emerging evidence that SO filling of the vitreous cavity and its removal may impact macular perfusion. So far, studies have not focused on choroidal sublayer perfusion, yet. (2) Methods: Optical coherence tomography angiography was applied in 19 patients with SO endotamponade before and four weeks after removal of SO. (3) Results: Perfusion of choriocapillaris increased significantly after SO removal, while perfusion of Haller’s and Sattler’s layer decreased significantly. (4) Conclusions: Removal of SO impacts choroidal perfusion and leads to a perfusion shift within choroidal sublayers. This study underlines that it is worth to conduct larger prospective studies that evaluate the choroidal perfusion and its functional implications in more detail.
