“…It has to be considered, that RD can have several different stages, and the surgical technique is variable, including endotamponade material. In a recent review Christou summarizes, that the exact macular vascular density changes are still not clear due to the diversity of RRD and surgical techniques [24].…”

The study aimed at a quantitative evaluation of macular vasculature after primary repair of rhegmatogenous retinal detachment (RRD) in correlation with the elapsed postoperative time. Optical coherence tomography angiography (OCT-A) was performed in 66 eyes of 33 patients in a retrospective case-control study: superficial and deep retinal vessel density (VD) of the whole image, fovea, parafovea, non-flow area, and foveal avascular zone (FAZ) were measured. Data of eyes with RRD were compared to the healthy fellow eyes in 3 groups according to the elapsed time after surgery: RD1: 6–12 months (n = 10), RD2: 1–2 years (n = 10), and RD3: 2–10 years (n = 13). In RD1 VD was significantly lower in the superficial parafoveal, deep parafoveal, and deep whole area compared to the fellow eyes. In RD3 VD was significantly lower in the superficial fovea, parafovea, whole image, and deep fovea, the non-flow area was significantly enlarged. OCT-A demonstrated a significant reduction in the superficial and deep regions of the macular vasculature after the repair of RRD. The deep area is more affected in the early postoperative period and the superficial region and the extent of the non-flow area are more involved after a longer postoperative time.

“…OCT-A, even though it is not a dynamic evaluation (as fluorescein angiography), is able to detect vessel architecture thus evaluate the perfusion function of macular vessels. The normal scan mode can precisely reflect surface or deep capillary flow densities on the macula and precisely capture the changes in the foveal avascular zone (FAZ) [ 13 , 14 ].…”

Changes of macular vessel density and thickness in gas and silicone oil tamponades after vitrectomy for macula-on rhegmatogenous retinal detachment

Purpose To investigate the macular vessel density and thickness in macular-on rhegmatogenous retinal detachment (RRD) after vitrectomy with gas and silicone oil (SO) tamponade. Methods Patients with macular-on RRD eyes, treated with a single successful vitrectomy with gas or SO tamponade and a minimum 30 months follow-up, were reviewed. Best-corrected visual acuity (BCVA), macular vessel density and retinal thickness by using optical coherence tomography angiography, were compared to the contralateral eyes. Results Sixteen eyes with gas tamponade and 17 eyes with SO tamponade were included in the study. LogMAR best-corrected visual acuity (BCVA) slightly improved from 0.25 ± 0.18 (Snellen 20/36) to 0.17 ± 0.23 (Snellen 20/30) in eyes with gas tamponade, and decreased from 0.30 ± 0.22 (Snellen 20/40) to 0.49 ± 0.28 (Snellen 20/62) in eyes with SO tamponade. The parafoveal vessel densities in superficial vascular complex (SVC) and the corresponding inner retinal thickness (IRT) were similar between the affected eyes and the contralateral eyes in gas tamponade group (P = 0.578, P = 0.943), while significantly reduced in the affected eyes, compared to the contralateral eyes in SO tamponade group (P < 0.001, P < 0.001). Conclusion Eyes in SO tamponade group had worse BCVA, lower SVC vessel densities and thinner corresponding IRT after vitrectomy for macular-on RRD, than those in gas tamponade 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].…”

“…The diversity of their results possibly reflects the reasons for variability of final VA. Therefore, we sought to investigate the potential for recovery of postoperative VA by analyzing OCT-A based studies and identifying parameters in macular capillary plexus as biomarkers [12].…”

“…Changes in the foveal capillary plexus indicate the presence of ischemic damage to retinal vessels causing distortion of FAZ area. Of note, authors do not serve unequivocal perspectives in literature [12][13][14][15]17,19,20,[22][23][24]28]. Enlargement of SCP or DCP FAZ area has been attributed to tissue hypoxia leading to foveal derangement and capillary dropout [14].…”
