“…Out of 16 articles reviewed, the findings of 11 articles were meta-analyzed [ 13 – 18 , 20 , 22 – 25 ]. The findings of the other five articles are presented only quantitatively due to the lack of necessary information in the statistical analysis [ 5 , 6 , 19 , 21 , 26 ]. Of the selected articles, 13 studies were retrospective, two were prospective, and one was cross-sectional.…”

Background To evaluate the effects of intravitreal silicone oil (SO) on the retinal and choroidal thickness in eyes with rhegmatogenous retinal detachment (RRD). Methods A literature search was performed in Web of Science, Scopus, ProQuest, Embase, Clinical Key, Science Direct, Cochrane Library, and Springer, as well as Persian databases, including IranDoc, MagIran, SID, MOH thesis, and MOH articles until June 2020. Two reviewers independently searched and extracted the data. Results Sixteen studies (n = 391) met the inclusion criteria. The meta-analysis showed that the SO tamponade could significantly reduce the central macular thickness (CMT) in patients with RRD as compared to gas tamponade WMD = − 14.91; 95% CI: − 22.23, − 7.60; P < 0.001, I2 = 71%). No significant change was found in CMT between the eye with SO tamponade (after SO removal) and the fellow healthy eye in patients with RRD (WMD = − 3.52; 95% CI: − 17.63, 10.59; I2 = 68.6%). Compared to the preoperative stage, the SO tamponade could significantly reduce the subfoveal choroidal thickness in patients with RRD (WMD = − 18.67, 95% CI: − 30.07, − 1.28; I2 = 80.1%). However, there was no significant difference in the subfoveal choroidal thickness before and after SO removal (WMD = − 1.13, 95% CI: − 5.97, 3.71; I2 = 87.6%). Conclusion The SO tamponade had a significant effect on the reduction of retinal layers and the subfoveal choroidal thickness.

“…Besides, the results of these two studies showed a decrease in the inner retinal layers in eyes with SO tamponade as compared to the fellow healthy eyes. Moreover, a study by Roohipoor et al showed that CMT was significantly reduced after SO tamponade removal compared to the fellow healthy eye (P = 0.002) [ 26 ].…”

“…Recently, several studies have reported the anatomical and functional changes in eyes that underwent SO tamponade [9,19]. Roohipoor et al [20] demonstrated decreased retinal VD as well as decreased retinal thickness in the fovea in macular-off RRD with SO tamponade when compared with that in healthy control eyes. However, they only included patients with macular-off RRD.…”

Purpose We aimed to evaluate microvascular changes on optical coherence tomography angiography (OCTA) in patients with rhegmatogenous retinal detachment (RRD) who underwent silicone oil (SO) tamponade and compare changes according to macular involvement. Methods This retrospective study included 48 patients with unilateral RRD who underwent vitrectomy and SO tamponade and were stable after SO removal. Control data were obtained from the fellow healthy eye. Ophthalmic examinations, including best corrective visual acuity (BCVA) and OCTA, were conducted. Differences in vascular density (VD) in different sections of the macula and differences in the foveal avascular zone (FAZ) were analyzed between the affected eyes and control eyes. Subgroup analyses according to macular involvement were performed. Results Baseline BCVA and duration of SO tamponade were associated with postoperative BCVA (p<0.001, p = 0.03, respectively). The average VD in the deep capillary plexus (DCP) and the VD of the nasal parafoveal area in both the superficial capillary plexus (SCP) and the DCP decreased relative to those in the control eyes (p = 0.026, p = 0.028, and p = 0.031, respectively). The FAZ area in the DCP and in the SCP also increased when compared with that in the controls (p = 0.043, p = 0.002, respectively). In addition, the macular-off RRD group had lower VD in the nasal parafoveal area of the DCP than the macular-on RRD group. Conclusion SO tamponade could cause microvascular changes, especially in the nasal parafoveal area. The macular-off RRD group were affected more than the macular-on RRD group.

“…Retinal microvasculature of the two capillary plexuses (SCP and DCP) and choriocapillary network are evaluated in detail, while ICP is not always included in most studies due to projection artifact [9][10][11]. Notably, the currently available evidence concerning potential macular alterations as seen on OCT-A after RRD repair has stirred controversy as the results of the studies have not been unequivocally confirmed [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”

“…Obviously, gas is a widely utilized tamponading agent and its use accounts for a large fraction of cases [32][33][34][35][36][37][38][39]. Indeed, most studies comprehensively examine OCT-A characteristics of RRD eyes after PPV with gas tamponade [13][14][15][16][17][18][19][20][21][22][23][29][30][31], while there is limited evidence of those treated by PPV with SO or by scleral buckle [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. The primary anatomical success rates for RRD repair by PPV have been found to range from 64% to 96%.…”
