Quantitative Microvascular Change Analysis Using a Semi-Automated Algorithm in Macula-on Rhegmatogenous Retinal Detachment Assessed by Swept-Source Optical Coherence Tomography Angiography. Diagnostics (Basel) 2024; 14:750. [PMID: 38611663 PMCID: PMC11011992 DOI: 10.3390/diagnostics14070750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 03/21/2024] [Accepted: 03/27/2024] [Indexed: 04/14/2024] Open
Abstract
PURPOSE The purpose of this study was to objectively evaluate the longitudinal changes observed in the retinal capillaries in eyes with macula-on rhegmatogenous retinal detachment (RRD), assessed with optical coherence tomography angiography (OCTA), and to assess the role of these microvascular measures as potential biomarkers of postoperative visual outcomes. METHODS This was a prospective, longitudinal study conducted on consecutive patients who underwent 25 G pars plana vitrectomy for primary RRD. The vessel area density (VAD), vessel skeleton density (VSD), and vessel diameter index (VDI) were assessed in the superficial (SCP) and deep (DCP) capillary plexuses. RESULTS Twenty-three eyes with macula-on RRD were included in the study. The mean preoperative VDI, VAD, and VSD of the RRD eye were 18.6 ± 1.1, 0.43 ± 0.02, and 0.17 ± 0.01 in the SCP; and 18.6 ± 0.6, 0.38 ± 0.03, and 0.15 ± 0.01 in the DCP, respectively. At month 6, eight (34.8%) eyes achieved a best-corrected visual acuity (BCVA) gain ≥ 0.1 LogMAR. A preoperative VDI > 17.80, VSD > 0.170, and VDI-change > -0.395 in the SCP; and VDI > 18.11 and VDI change > -0.039 in the DCP were predictors of achieving a BCVA-gain ≥ 0.1 LogMAR. CONCLUSIONS The preoperative VDI in SCP and DCP, the preoperative VSD in SCP, and their changes from preoperative values were predictors of visual outcomes. A quantitative OCTA analysis of capillary density and morphology may represent a potential predictive tool for surgical outcomes in RRD. The results reported in this study suggest that OCTA is a useful ancillary test for clinical disease management.

Abstract
Purpose: To evaluate the effect of mean ocular perfusion pressure on the foveal avascular zone (FAZ) area in eyes with successful retinal detachment (RD) surgery. Methods: This prospective pilot fellow eye-controlled study measured the intraoperative mean ocular perfusion pressure in eyes having surgery for rhegmatogenous RD (RRD). Postoperatively, the FAZ area was measured; the change was calculated as the difference in the FAZ area between the operated eye and the contralateral control eye. Results: The study comprised 8 patients with a mean age (±SD) of 53.38 ± 13.92 years. The mean superficial FAZ area was not different between operated eyes and control eyes, while the deep FAZ area was significantly larger in operated eyes. There was a strong negative correlation between the mean ocular perfusion pressure and the change in the deep FAZ area (Spearman ρ, -0.73; P = .04); the correlation between the mean ocular perfusion pressure and the change in the superficial FAZ area was not significant (Spearman ρ, -0.24; P = .57). A significant linear regression was found between the mean ocular perfusion pressure and the change in the deep FAZ area (R2 = 0.388). The predicted enlargement of the deep FAZ area was 0.03 mm with every 1 mm Hg decrease in the mean ocular perfusion pressure. Conclusions: Lower intraoperative mean ocular perfusion pressure is associated with enlargement of the deep FAZ area in eyes having successful RRD surgery.

Abstract
PURPOSE The current study utilizes microperimetry and optical coherence tomography angiography (OCTA) to assess the optic nerve head vasculature, retinal microvasculature, and retinal sensitivity before and after silicone oil (SO) removal. METHODS This prospective observational case series study involved 30 eyes subjected to silicone oil endotamponade. Microperimetry and OCTA were utilized to assess the vascular density (VD) of the macula and optic nerve head, as well as the retinal sensitivity (RS), of the participants preoperatively and 1 month following SO removal. The correlation between the various parameters of OCTA and microperimetry was evaluated. RESULTS There was a significant improvement in the postoperative best-corrected visual acuity (BCVA) (p-value < 0.001) and the postoperative total RS, which was 6.38 ± 2.34 dB as compared to a mean preoperative total RS of 5.04 ± 2.06 dB (p-value < 0.001) and showing a significant increase in all rings. However, there was no significant difference in the pre and postoperative macular VD. On the other hand, there was a significant increase in the postoperative VD of the whole disk and the peripapillary capillary plexus, p-values < 0.001 and 0.002, respectively. CONCLUSION The removal of SO resulted in significant improvements in retinal sensitivity, vision, and optic nerve perfusion. However, no significant change was observed in macular VD.

Abstract
Alterations in microvasculature represent some of the earliest pathological processes across a wide variety of human diseases. In many organs, however, inaccessibility and difficulty in directly imaging tissues prevent the assessment of microvascular changes, thereby significantly limiting their translation into improved patient care. The eye provides a unique solution by allowing for the non-invasive and direct visualization and quantification of many aspects of the human microvasculature, including biomarkers for structure, function, hemodynamics, and metabolism. Optical coherence tomography angiography (OCTA) studies have specifically identified reduced capillary densities at the level of the retina in several eye diseases including glaucoma. This narrative review examines the published data related to OCTA-assessed microvasculature biomarkers and major systemic cardiovascular disease. While loss of capillaries is being established in various ocular disease, pilot data suggest that changes in the retinal microvasculature, especially within the macula, may also reflect small vessel damage occurring in other organs resulting from cardiovascular disease. Current evidence suggests retinal microvascular biomarkers as potential indicators of major systemic cardiovascular diseases, including systemic arterial hypertension, atherosclerotic disease, and congestive heart failure.

Abstract
BACKGROUND This study evaluated the vascular changes in the macular and peripapillary regions before and after silicone oil (SO) removal in patients with rhegmatogenous retinal detachment. METHODS This single-center case series assessed patients who underwent SO removal at one hospital. Patients who underwent pars plana vitrectomy and perfluoropropane gas tamponade (PPV + C3F8) were selected as controls. Superficial vessel density (SVD) and superficial perfusion density (SPD) in the macular and peripapillary regions were assessed by optical coherence tomography angiography (OCTA). Best-corrected visual acuity (BCVA) was assessed using LogMAR. RESULTS Fifty eyes were administered SO tamponade, 54 SO tamponade(SOT) contralateral eyes, 29 PPV + C3F8 eyes, and 27 PPV + C3F8 contralateral eyes were selected. SVD and SPD in the macular region were lower in eyes administered SO tamponade compared with SOT contralateral eyes (P < 0.01). Except for the central area, SVD and SPD in the other areas of the peripapillary region were reduced after SO tamponade without SO removal (P < 0.01). No significant differences were found in SVD and SPD between PPV + C3F8 contralateral and PPV + C3F8 eyes. After SO removal, macular SVD and SPD showed significant improvements compared with preoperative values, but no improvements in SVD and SPD were observed in the peripapillary region. BCVA (LogMAR) decreased post-operation and was negatively correlated with macular SVD and SPD. CONCLUSIONS SVD and SPD are decreased during SO tamponade and increased in the macular region of eyes that underwent SO removal, suggesting a possible mechanism for reduced visual acuity during or after SO tamponade.

Abstract
BACKGROUND The goal of this study was to investigate macular microvascular changes using optical coherence tomography angiography (OCTA) at one year after successful rhegmatogenous retinal detachment (RRD) surgery. METHODS We performed a cross-section study including RRD treated by pars plana vitrectomy (PPV) with or without scleral buckling and SF6 tamponade. After 12 months, DRI-Triton SS-OCTA was performed. Superficial and deep retinal capillary plexuses (SCP and DCP), choriocapillaris (CC) vessel density (VD), and foveal avascular zone (FAZ) morphology were analyzed. Results were compared with the unaffected contralateral eye. RESULTS Sixty eyes were included. We observed an increase in VD in the central area of both the SCP and DCP in macula-off eyes treated with PPV + SB and in the SCP of macula-off eyes treated with PPV. Macula-off eyes had a diminished VD for both plexuses in the superior quadrant and in the SCP inferior quadrant in those treated with PPV + SB. The CC flow was diminished in the temporal quadrant of macular-off eyes treated with PPV + SB. Healthy eyes presented higher diameter values than macula-off eyes treated with PPV + SB. FAZ horizontal and vertical diameters were smaller in patients with macula-off RRD vs. macula-on RRD and control groups. CONCLUSION Macular vascularity remains almost unchanged one year after successful RRD surgery, irrespective of the surgical technique or prior macular status.

J Clin Med 2022; 11:jcm11123498.

Abstract
Background: In this study we aimed at investigating macular perfusion/anatomical changes in eyes with early onset rhegmatogenous retinal detachment (RRD) after prompt surgery within 24 hours, comparing a bisected macula and not bisected macula RRD. Methods: In this prospective observational study, 14 eyes of 14 patients who underwent within-24 hours vitreoretinal surgery for early onset RRD were enrolled. Patients were further divided into two subgroups: the not bisected macula group (NBM group) and the bisected macula group (BM group). At baseline and 3-month follow up, macular architecture and vessel analysis were assessed using optical coherence tomography angiography (OCTA) imaging. In detail, quantitative and qualitative analyses of the macular area were performed to quantify topographical retinal perfusion changes after surgery, calculating the foveal avascular zone (FAZ), vessel density (VD) and vessel length density (VLD) at the superficial capillary plexus (SCP) and deep capillary plexus (DCP). Results: Most cases (43%) were superotemporal RRD. Primary retinal reattachment was obtained in all cases, without recurrences within 3-month follow up. After surgery, a significant FAZ enlargement was observed at both the SCP and DCP level (p < 0.001; p < 0.05), with a significant effect of time noted between the two time points in the NBM and BM subanalysis (F = 3.68; p < 0.017). An excellent functional outcome was maintained for the whole follow-up. On the other hand, after surgery, perfusion parameters did not change significantly apart from the vessel density of the inferior macular sector at the DCP level (p = 0.03). Conclusions: Our findings suggest that the macular perfusion of eyes with RRD is still preserved if the surgery is performed really promptly, thus highlighting the great importance of a correct timing for surgery. OCTA analysis allows for a better understanding of the pathophysiological mechanisms underneath early vascular microarchitecture modifications of the posterior pole in retinal detachment, differentiating the two types of RRD not completely involving the fovea (BM and NBM).

Abstract
PURPOSE To evaluate macular microvascular changes and their correlation with visual outcomes after rhegmatogenous retinal detachment (RRD) surgery. DESIGN Retrospective case series PARTICIPANTS: Seventy-four eyes successfully operated for RRD were included in the study. METHODS The area of the foveal avascular zone in the superficial capillary plexus, the vessel density in the superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillary plexus (CCP) were evaluated using optical coherence tomography angiography (OCTA) at 1 and 6 months postoperatively. The fellow eyes were used as controls for comparison. MAIN OUTCOME MEASURES The correlation between OCTA parameters and postoperative best-corrected visual acuity (BCVA) was assessed using a hybrid linear mixed model. We also analyzed the relationship between OCTA parameters and the integrity of the external limiting membrane (ELM) and ellipsoid zone (EZ) of photoreceptors. RESULTS The median vessel density in the DCP was significantly decreased in RRD eyes at 1 month (p=0.019), but gradually improved over time to reach the value of the fellow eyes at 6 months (p=1). There was no significant difference between the 2 groups in median foveal avascular zone area, vessel density in the SCP and in the CCP (p=0.579, p=0.618, p=0.068 and p=0.819, p=1 and p=1, respectively) at both 1 and 6 months postoperatively. Postoperative BCVA was positively correlated with the vessel density in the DCP (p=0.009) in multivariate analysis. Eyes with low 1-month vessel density in the DCP tended to have worse final BCVA (p=0.067). There was no correlation between the vessel density in the DCP and ELM and/or EZ integrity at both 1 (p=0.156) and 6 months postoperatively (p=0.161). Eyes with intact ELM and EZ at 6 months, however, had significantly higher 1-month vessel density in the DCP than those with disrupted ELM and/or EZ (p=0.027). CONCLUSION The vessel density in the DCP was affected in RRD eyes as well as associated with postoperative BCVA and the restoration of photoreceptor layers. It might thus serve as a predictor for visual recovery following successful RRD surgery.

Abstract
BACKGROUND To investigate the longitudinal retinal vascular and structural alterations by using OCTA following successful repair of retinal detachment (RD) by using silicone oil (SO) endotamponade. METHODS A prospective cohort study was performed on 24 eyes of 24 subjects; 17 of them with macula-off and seven with macula-on RD. At least four OCTA scans were generated for each study eye; two before and two after SO removal (SOR). At each session, retinal thickness (RT), vascular density (VD) in the superficial (SCP) and deep capillary plexuses (DCP) and foveal avascular zone(FAZ) size were measured within the fovea, parafovea and whole macular image. The changes in repeated measures of the same parameters especially before and after SOR were performed and compared within macula-on and macula-off groups and between fellow eyes. RESULTS "In the macula-off eyes, RT measurements within the whole macula, fovea and parafovea reduced as compared with their fellow eyes(p < 0.0001, p = 0.001 and p < 0.0001, respectively) and did not improve after SOR. Additionally, all of the whole macular, foveal, and parafoveal VD measurements at SCP and foveal VD at DCP were less than their fellow eyes after SOR (p = 0.026, p = 0.023 p = 0.026, and p = 0.002, respectively). In macula-on eyes, RT measurements decreased within the parafovea and whole macular area before SOR (p = 0.018 and p = 0.011, respectively) but improved after SOR. Also, VD measurements did not change during follow-up and were not statistically different than their fellow eyes (p > 0.05). FAZ enlargement was found in eyes with macular-off RD after SOR, whereas it was not observed with macular-on RD (p = 0.038and p = 0.237, respectively). CONCLUSIONS Treatment of macula-off RD with SO tamponade has been associated with vascular retinal abnormalities which did not improve following SOR. On the contrary, successful treatment of RD with SO tamponade in macula-on eyes VD measurements of SCP and DCP were not statistically different than their fellow eyes.

Abstract
Purpose: To evaluate the peripapillary changes after vitrectomy and silicone oil (SO) tamponade in eyes with rhegmatogenous retinal detachment (RRD). Methods: In this study, 25-gauge vitrectomy with SO tamponade was performed in 22 eyes with RRD. The radial peripapillary capillary (RPC) vessel density (VD) and retinal nerve fiber layer thickness (RNFLT) were assessed by optical coherence tomography angiography at 2, 4, 8, and 12 weeks postoperatively. The values of healthy fellow eyes were used as controls. Results: The global RPC VDs were significantly lower in the eyes with RRD than in fellow healthy eyes at 2 weeks (P < 0.001), and increased at 4 weeks, then decreased over time after surgery (F = 1.046, P = 0.377). The RPC VDs in the superior-hemifield were lower than those in the inferior-hemifield at 12 weeks postoperatively (t = −2.844, P = 0.010). The global RNFLTs decreased gradually after vitrectomy in the eyes with RRD (F = 1.312, P = 0.276). The RNFLTs in the superior-hemifield were thinner than those in the inferior-hemifield at 12 weeks postoperatively (t = −2.222, P = 0.037). The global, superior, and inferior RNFLTs were correlated with corresponding RPC VDs in the eyes with RRD at all time-points postoperatively (P < 0.05). Conclusion: RRD resulted in the decrease of RPC VDs. The RPC VDs recovered in the early postoperative period but were still lower than the normal level. Long-term application of SO tamponade resulted in the reduction of peripapillary VDs secondary to loss of RNFLTs.

Abstract
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.

Abstract
AIM To evaluate macular microvasculature changes in eyes after pars plana vitrectomy (PPV) and intraocular silicone oil (SO) tamponade for macula-off rhegmatogenous retinal detachment (RRD) using optical coherence tomography angiography (OCTA). METHODS Totally 19 eyes (19 patients) with macula-off RRD who underwent PPV and intraocular SO tamponade were retrospectively reviewed. The parafoveal superficial capillary plexus (SCP) vessel density (VD), deep capillary plexus (DCP) VD, choriocapillaris plexus (CCP) VD, and foveal macular thickness were evaluated using OCTA throughout 16wk postoperatively. The values of healthy fellow eyes were used as control. RESULTS The parafoveal SCP, DCP, and CCP VDs were significant increased over time in RRD eyes during the 12wk postoperatively, then decreased at 16wk postoperatively (all P<0.01). The ratios of RRD eyes and fellow healthy eyes (r/f ratios) of the SCP and DCP VDs were lower than those of the CCP VD postoperatively (all P<0.05). There were not significant differences in the r/f ratios between SCP and DCP VDs postoperatively (all P>0.05). CONCLUSION The parafoveal SCP, DCP, and CCP VDs gradually recover over time after PPV surgery with SO tamponade. Long-time SO tamponade might decrease postoperative macular VDs. Compared to parafoveal CCP VD, the parafoveal SCP and DCP VDs were more vulnerable in RRD eyes postoperatively.

Abstract
PURPOSE To evaluate the macular microvascularity with optical coherence tomography angiography (OCTA) in rhegmatogenous retinal detachment (RRD) which were successfully treated with pneumatic retinopexy (PR). METHODS Thirty eyes of thirty patients who were treated with PR (12 eyes with macula-off RRD and 18 eyes with macula-on RRD) were included in this prospective study. OCTA was used to evaluate the macular perfusion changes postoperatively at 1 and 3 months. The fellow eyes (30 eyes) were used as control for comparison. Parafoveal retinal thickness (RT) and best-corrected visual acuity (BCVA) were evaluated. RESULTS Vessel density (VD) in SCP, DCP and choriocapillaris plexus (CCP) flow area was significantly lower in the macula-off group one month after the PR (p < 0.001). In the macula-off group, VD in SCP, DCP and CCP flow area significantly increased at months 3 (p < 0.001, p < 0.001, p = 0.009). The inner RT, RT and FAZ decreased three months after PR (p < 0.001, p = 0.001, <0.001). The FAZ was significantly larger in the macula-off group at third months after PR (p < 0.001). The inner RT was higher in the macula-off group at third month (p = 0.012). There was no significant difference between the groups in means of final VD, CCP flow area and RT. There was also a negative correlation between the final BCVA (logMAR) and FAZ at month 3 (r = 0.776, p = 0.003). CONCLUSION Optical coherence tomography angiography evaluation of macular capillary plexuses may be useful for predicting vascular structural changes in patients undergoing PR.

Abstract
PURPOSE Emerging evidence has suggested that macular microcirculation and microstructural changes after rhegmatogenous retinal detachment (RRD) successful reattachment surgery are currently evaluated in detail by OCT-Angiography (OCT-A). New imaging technology has revealed the existence of microscopic macular changes, even in cases that retinal morphology appears to be normal in fundus biomicroscopy. The use of OCT-A for the examination of foveal characteristics has attracted significant attention in recent years as the technique offers a potential explanation of the suboptimal recovery of visual acuity and incomplete restoration of the macula despite anatomical repair. However, the available evidence that is needed to establish the OCT-A parameters as predicting factors in clinical practice is both limited and contradictory. METHODS A detailed review of the literature was conducted. The association of OCT-A characteristics with postoperative visual acuity after RRD surgery, including vitrectomy with gas tamponade and in some cases scleral buckle, was extensively analyzed. RESULTS A comprehensive update on microcirculation and microstructural changes of the macula using OCT-A after RRD repair may indicate potential factors of functional outcomes in clinical practice. CONCLUSION A review of the existing literature sheds light on the microvascular changes of the macular capillary plexus that may significantly affect functional outcomes after RRD surgery. The current article discusses important aspects of key publications on the topic, highlights the importance of long-term effectiveness of these possible prognostic factors and proposes the need for further future research.

Abstract
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.

Abstract
Purpose: To evaluate macular capillary plexus changes with OCT-angiography with regard to macular detachment duration in macula-off rhegmatogenous retinal detachment (RRD).Methods: 23 eyes of 23 patients were included in this retrospective case-control study and were divided into 2 groups. Group-A had a macular detachment duration of 0 to 10 days and group-B of 11 to 30 days. All eyes underwent a single successful pars plana vitrectomy (PPV) and gas tamponade. We analysed the OCT-A characteristics and visual outcomes at 12 weeks postoperatively in the 2 groups. The fellow eye was used as control.Results: Vessel density (VD) and flow density (FD) in the superficial capillary plexus (SCP) were significantly lower in group-B (p < .01) than in group-A and control. FAZ SCP in both groups was significantly larger than the control (p < .01), although it did not differ significantly between the two groups (p = 1.000). BCVA was significantly lower in group-B compared to group-A (p < .01). BCVA was positively correlated with VD SCP in group B (p = .015), but not in group-A. Postoperative BCVA had no correlation with FAZ SCP in both groups.Conclusions: The macular detachment duration could be a predicting factor of flow density in macular capillary plexus which in turn might be an indicator of visual outcomes in chronic cases.

Abstract
PURPOSE To examine the changes in retinal microvasculature in association with retinal layers' condition in patients with rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 89 patients with macula off RRD, who were successfully treated with PPV and gas tamponade without internal limiting membrane peeling, in two centers. All participants underwent best corrected visual acuity (BCVA) measurement, slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography (SD-OCT) and optical coherence tomography angiography (OCTA) at week 5, month 3 and month 6 postoperatively. The fellow untreated eyes were also examined and served as control data. RESULTS A statistically significant enlargement in foveal avascular zone (FAZ) in both superficial capillary plexus (SCP) and deep capillary plexus (DCP), accompanied with a statistically significant thinning of inner retinal layers, was noticed 5 weeks postoperatively. These changes, namely FAZ enlargement and thinning of inner retinal layers, in the operated eyes compared to the fellow eyes, remained unchanged till month 6 postoperatively. BCVA improved significantly from week 5 to months 3 and 6 postoperatively. The improvement in BCVA was associated with the gradual ellipsoid zone (EZ) recovery from the first (week 5) till the last examination (month 6). CONCLUSIONS The FAZ enlargement in the operated eyes was accompanied with a statistically significant thinning in the inner retinal layers. Inter-correlation of BCVA and EZ integrity was noticed.

Abstract
PURPOSE The purpose of this prospective study was to evaluate potential predictive factors of long-term postoperative outcomes in patients with macula-off rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 86 patients diagnosed with macula-off RRD, who underwent PPV. Demographic characteristics and preoperative characteristics of RRD were recorded, while best corrected visual acuity (BCVA) was measured preoperatively and at specific postoperative time points (6 weeks and 6, 12, and 24 months). In addition, spectral domain-optical coherence tomography (SD-OCT) characteristics at postoperative week 6 were assessed as potential factors affecting the long-term postoperative visual outcome 24 months after PPV for RRD. RESULTS Increasing age, duration of RD of more than 1 week, presence of proliferative vitreoretinopathy, increasing central retinal thickness, ellipsoid zone disruption, and external limiting membrane disruption were significantly associated with a worse BVCA. BCVA was not associated with gender, lens status, the location of breaks, the gas tamponade agent used in PPV, the presence of subretinal fluid, and intraretinal fluid. CONCLUSIONS It is important to determine predictive factors for visual outcomes in order to inform patients about their prognosis and help in the decision-making process for patient management.

Abstract
PURPOSE To analyse the postoperative foveal avascular zone (FAZ) area, superficial vessel density (SVD) and deep vessel density (DVD) and their correlation with functional (best-corrected visual acuity, BCVA) and anatomical outcomes (foveal macular thickness, FMT) after surgery for rhegmatogenous retinal detachment (RRD) repair. METHOD Patients with RRD eyes, successfully treated with a single pars plana vitrectomy (PPV) with gas tamponade and a minimum 12 months follow-up, were re-examined. Foveal avascular zone (FAZ) area, SVD, DVD and FMT were evaluated by using optical coherence tomography angiography (OCTA) and compared to fellow eye. RESULTS Fifty-six patients with macula-on and 37 with macula-off RRD were included in the study. In both groups, no difference in FMT and FAZ area was found compared to fellow eyes. In macula-on RRD eyes, a lower parafoveal DVD (p = 0.001) was detected; FAZ area was related to FMT (p = 0.025), and the postoperative BCVA was correlated with parafoveal DVD (p = 0.010) and FAZ area (p = 0.003). In macula-off RRD eyes, lower parafoveal SDV (p = 0.012), and foveal and parafoveal DVD (p = 0.012 and p < 0.001, respectively) were observed. BCVA was related to FAZ area (p = 0.012), foveal SVD (p = 0.005) and parafoveal DVD (p = 0.010). CONCLUSION Rhegmatogenous retinal detachment eyes successfully treated with PPV had lower vessel density in the superficial and deep retinal plexus compared to fellow healthy eyes; BCVA was related to FAZ area and vessel density.

Abstract
PURPOSE To examine the retinal layers' changes and alterations in retinal microvasculature in patients with rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 103 patients with RRD, 85 macula off and 18 macula on, who were treated with PPV and gas tamponade without internal limiting membrane peeling, in two centers. All participants underwent best corrected visual acuity measurement, slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography and optical coherence tomography angiography at week 5 and at month 6 postoperatively. The fellow untreated eyes were also examined and served as control data. RESULTS A statistically significant enlargement in foveal avascular zone (FAZ) in both superficial capillary plexus (SCP) and deep capillary plexus (DCP) was noticed 5 weeks postoperatively in patients with RRD treated with PPV compared to the fellow eyes and remained 6 months after surgery. The FAZ enlargement in the operated eyes was accompanied with a statistically significant thinning of the inner retinal layer. In addition, there was a significant decrease in foveal and parafoveal vessel density (VD) in both SCP and DCP in the operated eyes compared to control eyes at week 5 postoperatively, which also remained at postoperative month 6. CONCLUSIONS The study demonstrated that patients with RRD treated with PPV presented changes in the retinal microvasculature in both SCP and DCP, including enlargement of FAZ and decrease in VD. These changes seemed to be associated with inner retinal layer thinning.

Abstract
Objective To characterize the microvascular retinal changes after repair of macula-off rhegmatogenous retinal detachment (RRD) using optical coherence tomography angiography (OCT-A). Patients and Methods A retrospective review of patients who underwent repair of macula-off RRD. Fellow unaffected eyes were used as controls. Post-operative OCT-A allowed comparison of vessel density (VD) and foveal avascular zone (FAZ) area in the superficial and deep retinal capillary plexus (DCP) as well as VD in the choriocapillaris layer. Results Seventeen eyes of 17 RRD patients were included in the final analysis. There was a reduction in VD of the deep retinal capillary plexus in affected eyes compared to fellow eyes (p = 0.046). RRD eyes with reduced VD in DCP compared with their fellow control eyes had worse visual acuity after repair compared to those without (p = 0.032). No significant microvasculature changes were detected in the FAZ area and VD in the superficial capillary plexus and choriocapillaris compared to fellow eyes. Conclusion In macula-off RRD eyes, significant microvascular changes were detected in the DCP using OCT-A even after successful anatomical repair. Decreased VD in the DCP compared to the fellow healthy eyes was correlated with worse visual acuity.

Abstract
BACKGROUND To investigate different tamponade effects of intravitreal silicone oil (SO) and sterilized air on macular vasculature and structure after successful retinal repair for macular-on rhegmatogenous retinal detachment (RRD) patients. METHOD 21 eyes (21 patients) with macular-on RRD underwent single pars plana vitrectomy following intravitreal SO or sterilized air (Gas) tamponade. Optical Coherence Tomography (OCT) and angiography were used to evaluate retinal layer thickness and flow density (FD) changes throughout the observation period of 12 weeks. Retinal layers were segmented into 7 sets: NFL, GCL + IPL, INL, OPL, ONL + IS, OS+RPE and BRM. Macular perfusion system was segmented into superficial and deep capillary plexus flow density (SCPFD, DCPFD), and choriocapillaries plexus flow density (CCPFD). RESULT Compared to Gas tamponade, SO tamponade led to more decrease in both superficial and deep retinal blood flow during observation. NFL thickness was found to decrease in both Gas tamponade and SO tamponade eyes. SO tamponade resulted in more pronounced decrease which led to significant intergroup difference. Opposite changing trends were found in GCL + IPL and ONL + IS thicknesses due to different means of tamponade. SO tamponade caused thicknesses of these two segmented layers to decrease, which led to significant intergroup differences. SO tamponade also led to more decrease in INL, OPL thicknesses. No significant intergroup difference of choroidal thickness was observed. CONCLUSION Compared to gas, silicone oil could have more negative tamponade effects on both fundus vasculature and structure.

Abstract
Purpose The aim of this study was to evaluate the foveal avascular zone (FAZ) of healthy subjects and examine the magnification effect. Methods A total of 33 healthy volunteers were enrolled and all subjects were eligible for analysis. Optical coherence tomography angiography (OCTA) examination scanned 3 × 3 mm of the macular area. The FAZ area was measured on the superficial OCTA en face image with and without correction by axial length. The relationship between changes in the FAZ area after correction with the axial length was examined. Results The mean age was 21.9 ± 0.6 years. The mean axial length was 24.87 ± 1.17 mm and mean spherical equivalent (SE) value was -3.64 ± 2.83 diopters (D). The FAZ area was 0.26 ± 0.10 mm2 before the axial length correction and 0.27 ± 0.10 mm2 after the correction. In the eyes that had an axial length longer than or equal to 26 mm or SE less than or equal to -6 D, the FAZ area after correction was significantly larger than that before correction (p < 0.01). The change of FAZ area after correction with axial length was significantly correlated with the axial length (R 2 = 0.88, p < 0.01) or SE value (R 2 = 0.55, p < 0.01). Conclusion FAZ areas were comparable to previous reports. In high myopic cases, the magnification effect needs to be considered when evaluating the FAZ area.

Abstract
Changes in retinal vasculature and ocular circulation may play an important role in the glaucoma development and progression. We evaluated the vertical asymmetry across the temporal raphe of the deep retinal layer vessel density, using swept-source optical coherence tomography angiography (SS-OCTA), and its relationship with the central visual field (VF) loss. Thirty-four eyes of 27 patients with open-angle glaucoma were included. SS-OCTA macular scanning was performed within a 3 × 3 mm (300 × 300 pixels) volume, centred on the fovea. The relationships between the vertical asymmetrical deep retinal vessel density reduction (ADRVD) across the temporal raphe and various ocular parameters were analysed. Twenty-two glaucomatous eyes with ADRVDs had central VF loss. Contrarily, ADRVDs were not found in any of the 12 eyes without central VF loss. Thirteen eyes (59.1%) with central VF loss had ADRVDs topographically corresponding to the central VF loss and macular ganglion cell complex thinning. The glaucomatous eyes with ADRVDs exhibited inferior rather than superior central VF loss (P = 0.032). Thus, ADRVD specifically indicates the glaucomatous central visual loss. Further analysis of ADRVD may improve our understanding on glaucoma pathogenesis, offering new treatment insights.

Abstract
Purpose: To investigate the efficacy and safety of intravitreal dexamethasone implant as initial and only treatment for macular oedema after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).Methods: This study included 14 patients, who were diagnosed with macular oedema after PPV for RRD and who were treated with intravitreal dexamethasone implant. Patients were examined at the time of macular oedema diagnosis (baseline) and 1, 6 and 12 months after treatment, using best corrected visual acuity (BCVA) measurement and optical coherence tomography (OCT).Results: The mean BCVA at baseline was 0.72 ± 0.29 logMAR and improved significantly to 0.37 ± 0.21, 0.42 ± 0.19 and 0.35 ± 0.22 logMAR at month 1, 6 and 12 after treatment with dexamethasone implant. The mean central retinal thickness (CRT) was 623 ± 142 μm at baseline and decreased significantly to 339 ± 163 μm, 428 ± 131 μm and 356 ± 147 μm at month 1, 6 and 12 after treatment. Total resolution of macular oedema was observed in 10 out of 14 patients (71.4%) at month 12. Ellipsoid zone was intact in 71.4% of patients at the end of the follow-up, while 71.4% of patients received only one implant until the end of the 12-month follow-up. No adverse events were observed.Conclusions: Intravitreal dexamethasone implant was found to be effective and safe as initial treatment for macular oedema after PPV for RRD.

Abstract
Purpose: To investigate the incidence of macular edema after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair, the factors affecting its development and the efficacy of intravitreal dexamethasone implant for its treatment.Methods: Participants in this study 86 patients with RRD. All patients were examined postoperatively and those with macular edema were treated with intravitreal dexamethasone implant and were followed-up for 12 months.Results: 14 out of 86 patients presented macular edema post PPV for RRD repair. Patients with preoperative macula off RRD, duration of RRD >1 week and proliferative vitreoretinopathy were more prone to develop macular edema. There was a statistically significant improvement in best corrected visual acuity and central retinal thickness at month 12 post intravitreal dexamethasone implant compared to baseline.Conclusions: The incidence of macular edema post PPV for RRD repair was found to be 16.3%. Intravitreal dexamethasone implant seemed to be safe and effective in cases with post-PPV macular edema after RRD repair.
