Real-world experience with fluocinolone acetonide intravitreal implant in patients with diabetic macular edema.

OBJECTIVES: to evaluate long-term effectiveness and safety of fluocinolone acetonide (FAc) implant used as second-line treatment in patients with persistent diabetic macular edema (DME). METHODS: retrospective data chart review of 241 pseudophakic eyes of 178 patients treated with FAc from July 2017 to December 2021 in 10 medical retinal units in Italy. The primary endpoint was the change of best-corrected visual acuity (BCVA) and central macular thickness (CMT) at 2 years. A Student's paired t-test was used. Additional therapies for DME and intraocular pressure (IOP)-related events were also evaluated. RESULTS: efficacy of FAc was assessed in a subset of 111 eyes with at least 24 months of follow-up. Mean BCVA increased at 2 years by 5.1 ETDRS letters (95%CI = 2.6-7.5; p < 0.001) while mean CMT decreased by 189 µm (95% CI 151-227; p < 0.001). Thirty-eight of these eyes (34.2%) needed additional intravitreal treatments, mainly anti-VEGF. Safety was evaluated on the entire cohort of 241 eyes treated with FAc. Overall, 66 eyes (27.4%) required emergent IOP-lowering medications (typically within the first-year post FAc) while 14 eyes (5.8%) underwent trabeculectomy, mostly during the second year of follow-up. CONCLUSION: FAc implant provides a substantial long-term functional and anatomical benefit when used as second-line treatment in eyes with DME. IOP rise can be adequately managed with topical agents although some eyes may require IOP-lowering surgery.

Factors associated with the response to fluocinolone acetonide 0.19 mg in diabetic macular oedema evaluated as the area-under-the-curve.

OBJECTIVES: The area-under-the-curve (AUC) measures the average drug effect over time. We investigated the impact of baseline clinical and optical coherence tomography (OCT) factors on the response to fluocinolone acetonide (FAc) 0.19 mg implant in patients with diabetic macular oedema (DMO) as the AUC over 36 months. METHODS: Retrospective study of DMO eyes undergoing FAc with follow-up from 12 to 36 months. The AUC of the best-corrected visual acuity (BCVA) and the central macular thickness (CMT) were calculated with the trapezoidal rule. Demographic and clinical data at the time of FAc administration were collected, and associations with BCVA and CMT changes were investigated with linear mixed models. RESULTS: Eighty-nine eyes of 63 patients were enroled; median follow-up was 26 months. Mean±standard deviation (SD) AUCBCVA and AUCCMT after FAc injection were 0.24 ± 0.17 LogMAR/month and 179.6 ± 54.3 µm/month, respectively. Worse baseline BCVA (ß = 0.30 LogMAR/month, p < 0.001), higher AUCCMT after FAc administration (ß = 0.08 LogMAR/month, p < 0.001), diagnosis of type 1 diabetes (ß = -0.04 LogMAR/month, p = 0.04), and absent ELM/EZ layers (ß = 0.06 LogMAR/month, p = 0.01) were associated with worse vision over time (higher AUCBCVA). Eyes with higher CMT at baseline (ß = 9.61 µm/month, p < 0.001) and those with tractional DMO (ß = 24.7 µm/month, p = 0.01) had worse anatomic outcomes (higher AUCCMT). The need for additional treatments after FAc was also associated with higher AUCCMT (ß = 33.9 µm/month, p = 0.001). CONCLUSION: Baseline better visual acuity, lower macular thickness, and photoreceptors' layers integrity are associated with better functional response to FAc in DMO. Eyes with severe DMO at the time of implant or tractional oedema have worse anatomic response. These findings might guide clinicians in a more informed decisional algorithm in treating DMO.

Foveal eversion patterns in diabetic macular edema.

The aim of the present study was to describe foveal eversion patterns in diabetic macular edema (DME) and to assess their relationship with the course of the disease and the outcome. The study was designed as prospective, observational, with two years of follow-up. DME patients were divided in two groups, one treated by combined anti-VEGF injections and dexamethasone (DEX) implants, and the other treated by fluocinolone acetonide (FAc) implant with additional anti-VEGF retreatments if needed. Main outcome measures were foveal eversion prevalence, foveal eversion patterns, best-corrected visual acuity (BCVA), central macular thickness (CMT), structural OCT metrics, number of intravitreal injections. One hundred and forty-six eyes (146 patients; 80 males; mean age 67 ± 8 years) affected by already treated DME, with 84 eyes treated with anti-VEGF/DEX treatments (mean of 10 ± 3 injections) and 62 treated with FAc implant. Looking at the treatments administered before the inclusion into the study, 84 eyes (58%) were treated with anti-VEGF injections, whereas 62 eyes (42%) underwent a combination of anti-VEGF and corticosteroids implants. DME eyes showed statistically significant improvements of LogMAR BCVA and CMT over the 2-year follow-up. Foveal eversion was found in 83 eyes (57%), categorized as follows: Pattern 1a (16;19%); Pattern 1b (22;27%) and Pattern 2 (45;54%). BCVA improvement was detected in all the subgroups, excepting for Pattern 2, which showed also significantly worse structural OCT parameters. Pattern 1b and Pattern 2 were characterized by significantly higher prevalence of persistent DME (64% and 89% of cases, respectively). Foveal eversion patterns were correlated with progressively worse DME outcome. Foveal eversion may be associated to the loss of foveal homeostasis, with consequent poor response to intravitreal treatments and worse DME outcome.

Changes in Macular Perfusion After ILUVIEN® Intravitreal Implant for Diabetic Macular Edema: An OCTA Study.

INTRODUCTION: The aim of this study was to investigate changes in macular perfusion in patients affected by diabetic macular edema (DME) and treated with ILUVIEN® (fluocinolone acetonide intravitreal implant) 0.19 mg using optical coherence tomography angiography (OCTA). METHODS: This was a retrospective cohort study that included patients aged > 18 years with type 2 non-proliferative diabetic retinopathy (DR) and DME at baseline. All patients were treated with the ILUVIEN® implant. A minimum of two 6 × 6-mm OCTA scans were required to ensure that all cases had a baseline OCTA and an OCTA performed at 4 months of follow-up. Qualitative and quantitative comparisons were performed. RESULTS: Ten eyes from ten subjects were included in the analysis. Mean (± standard deviation) age of the study cohort was 57.1 ± 8.3 years. Mean parafoveal perfusion density (PD) at baseline was 64.1 ± 1.8% at baseline, increasing to 66.1 ± 2.9% (p = 0.013) at the 4-month follow-up visit. Mean parafoveal PD at baseline was 64.4 ± 2.1%, increasing to 65.2 ± 2.6% (p = 0.024) after 4 months. In the qualitative assessment, 60 regions (10 areas for each subject) were graded to assess changes in retinal perfusion between the baseline and follow-up visits. This assessment revealed that 24 regions (40.0%) were characterized by a qualitative increase in perfusion after treatment, while 22 (36.7%) and 14 (23.3%) regions were featured by a stability and reduction in retinal perfusion, respectively. CONCLUSION: OCTA analysis detects improvements in macular perfusion after treatment with ILUVIEN®. This improvement in macular perfusion may be associated with corticosteroid-related beneficial effects on leukostasis.

Efficacy of 0.19 mg Fluocinolone Acetonide Implant in Non-infectious Posterior Uveitis Evaluated as Area Under the Curve.

INTRODUCTION: This study reports the outcomes of fluocinolone acetonide intravitreal implant (FAc, Iluvien®, SIFI, Italy) in patients affected by macular edema secondary to chronic non-infectious uveitis of the posterior segment (NIU-PS). METHODS: This was a retrospective study of patients with NIU-PS and macular thickening undergoing FAc implant at San Raffaele Hospital (Milan, Italy). Clinical data, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), and central macular thickness (CMT), were collected at the time of FAc administration (baseline) and at 1, 6, and 12 months. The area under the curve (AUC) of the BCVA (AUCBCVA) and CMT (AUCCMT) was correlated with baseline factors; ß estimates and 95% confidence interval (CI) are provided. RESULTS: Ten eyes of seven patients (60 ± 12 years; 4 male, 57%) were included. The BCVA significantly improved from month 6 (p = 0.03). The CMT improved from month 1 and was persistently lower than baseline until month 12 (p < 0.001). The AUCBCVA correlated with baseline BCVA (ß = 2.5 logMAR; 95% CI 1.59-3.41; p < 0.001), while the mean AUCCMT positively correlated with the baseline CMT (ß = 2.1 µm; 95% CI 0.41-3.80; p = 0.02). No adverse events were recorded over 1 year. CONCLUSIONS: Better visual acuity at the time of FAc administration was associated with better visual function after FAc. Less severe macular edema correlated with better anatomic response. The FAc implant was a safe option for resolving macular edema secondary to NIU-PS.

Intraocular Pressure Changes Are Predictive of Ocular Hypertension Onset After Fluocinolone Acetonide Implant: Significant Cutoffs and the Role of Previous DEX Implant.

Background: Fluocinolone acetonide (FAc) implant represents a long-term strategy for the management of diabetic macular edema (DME). Because of the 3-year duration, the careful monitoring of the intraocular pressure (IOP) is necessary. The main aim of the study was to provide quantitative IOP cutoffs associated with the onset of IOP increases. Methods: The study was retrospectively conducted with 2-year of follow-up. We separately considered eyes with good IOP control (Group 1), eyes requiring IOP-lowering medications (Group 2) and eyes undergoing IOP-lowering surgery (Group 3). The statistical analysis assessed Delta% IOP changes over the 2-year follow-up. ROC analysis was performed to detect significant cutoffs associated with Group 2 and Group 3. IOP changes occurring after a previously administered dexamethasone (DEX) implant were also evaluated. Results: We included 48 eyes (48 patients), stratified as follows: Group 1 (25/48; 52%), Group 2 (19/48; 40%) and Group 3 (4/48; 8%). ROC analysis performed on IOP values detected 2-months later DEX implant showed a mean Delta IOP increase>24% significantly associated with IOP-lowering medications after FAc implant, whereas a mean Delta IOP increase>35% was significantly associated with IOP-lowering surgery after FAc implant. With respect to IOP changes occurred after FAc implant, our ROC analysis showed a mean Delta IOP increase>8% significantly associated with IOP-lowering medications, whereas a mean Delta IOP increase>15% was significantly associated with IOP-lowering surgery. DEX-related IOP changes showed 52% sensitivity and 100% specificity of FAc-related IOP increases. Conclusions: IOP changes provides clinically relevant cutoffs associated with the onset of FAc-related IOP increases.

Foveal Eversion: A Possible Biomarker of Persistent Diabetic Macular Edema.

INTRODUCTION: We aimed to evaluate the impact of foveal eversion on treatment response and persistent diabetic macular edema (DME). METHODS: The study was designed as interventional and prospective. DME eyes were treated with ranibizumab and/or dexamethasone (DEX) implants, or with fluocinolone acetonide (FAc) implants. FAc-treated eyes were eventually retreated by additional ranibizumab injections. Main outcome measure was the relationship between foveal eversion and both clinical outcome and persistent DME. RESULTS: Sixty-eight DME eyes (68 patients) treated by anti-VEGF/DEX and 50 FAc-treated eyes (50 patients) were recruited. The follow-up was 16 ± 3 months. The anti-VEGF/DEX group and FAc-treated group were statistically matched for age, sex, DME duration and previous number of injections (p > 0.05). Both groups experienced statistically significant improvements of both BCVA and central macular thickness (p < 0.01) at the end of the follow-up. Persistent DME was shown by 46% of anti-VEGF/DEX eyes and 42% of FAc-treated eyes. Foveal eversion was found in 50% of anti-VEGF/DEX eyes and in 44% of FAc-treated eyes. Its presence was associated with worse anatomical and visual outcome and higher persistence of DME in both groups (p < 0.01) and with higher retreatment percentages in FAc-treated eyes (p < 0.01). CONCLUSION: Foveal eversion is associated with worse clinical and morphological outcomes in DME.

The outcome of fluocinolone acetonide intravitreal implant is predicted by the response to dexamethasone implant in diabetic macular oedema.

BACKGROUND/OBJECTIVES: To investigate if the visual and anatomic response to the first dexamethasone implant (DEX) predicts the 12-month clinical outcome after shifting to fluocinolone acetonide (FAc) implant in patients with diabetic macular oedema (DMO). METHODS: Retrospective cohort study including pseudophakic patients with previously treated DMO, undergone one or more DEX injections before FAc. Functional and morphologic response to DEX was defined based on the best-corrected visual acuity (BCVA) and central macular thickness (CMT) changes after the first DEX, respectively. Steroid-response was defined as intraocular pressure (IOP) elevation ≥5 mmHg or IOP > 21 mmHg after any previous DEX exposure. Pairwise comparisons for BCVA, CMT, and IOP after FAc were performed with linear mixed models and a repeated-measure design. RESULTS: Forty-four eyes of 33 patients were included. Patients were shifted to FAc after a mean ± standard deviation of 4.6 ± 3.2 DEX injections. Overall, BCVA and CMT improved during the first 12 months after switching to FAc (p = 0.04 and p < 0.001, respectively). Only eyes with a good morphologic response to DEX had a significant CMT reduction after FAc (p < 0.001), while no significant relationship was found between BCVA improvement after DEX and after FAc. IOP elevation occurred in 9 eyes (20%) following DEX implant. These eyes carried a 20-fold increased risk of having an IOP rise after FAc (p < 0.001), with a non-linear relationship between the IOP increase after DEX and the one after FAc. CONCLUSION: The response to previous DEX may anticipate the morphologic response to subsequent FAc. Eyes with steroid-induced IOP elevation after DEX are at a high risk of IOP increase after FAc. The visual response after FAc was not associated with the visual response to previous steroids, indicating that FAc may have a role also in patients refractory to DEX implant.

Choriocapillaris flow impairment could predict the enlargement of geographic atrophy lesion.

AIM: To analyse the choriocapillaris (CC) flow status in the area that subsequently showed geographic atrophy (GA) expansion secondary to age-related macular degeneration (AMD) during 1-year follow-up, matching optical coherence tomography angiography (OCT-A) and fundus autofluorescence (FAF). METHODS: In this prospective longitudinal observational study, 30 eyes of 20 consecutive patients with GA secondary to AMD (mean age 75.5±7.4 years) were included. All patients underwent OCT-A and FAF at baseline and 1-year follow-up. Main outcome measures included analysis of perfusion density (PD) in the 'area surrounding GA margin' (between the GA border and 500 µm distance) in comparison with the 'control area' (area outside the 500 µm line), and of the 'expansion area' (area that subsequently developed GA expansion during 1-year follow-up). RESULTS: During the 1-year follow-up, visual acuity significantly decreased from 0.34±0.38 Logarithm of the Minimum Angle of Resolution (LogMAR) to 0.39±0.40 LogMAR (p<0.001), and mean GA area increased from 6.82±5.47 mm2 to 8.76±6.28 mm2 (p<0.001). CC PD of the area surrounding the GA margin revealed a significant flow impairment compared with control area (PD 0.679±0.076 and 0.734±0.057, respectively (p<0.001)). Furthermore, the PD of the expansion area showed a greater CC flow impairment in comparison to the remaining area surrounding GA margin (p<0.001). CONCLUSIONS: We reported a greater CC impairment in the area that subsequently developed GA expansion, suggesting that the CC flow impairment could predict the enlargement of GA lesion. The CC impairment could be considered as a new a risk factor for GA progression and a biomarker to be measured to determine efficacy of new interventions aiming to slow progression of GA.

Optical Coherence Tomography Biomarkers of Inflammation in Diabetic Macular Edema Treated by Fluocinolone Acetonide Intravitreal Drug-Delivery System Implant.

INTRODUCTION: The fluocinolone acetonide (FAc) intravitreal drug-delivery system implant is a recent, second-line, intravitreal drug for the management of diabetic macular edema (DME). FAc acts against DME with a major anti-inflammatory effect. Despite the already proved efficacy, a number of patients still show persistent DME and require anti-VEGF retreatment. The main aim of the present study was to assess the relationship between quantitative biomarkers of inflammation and both DME recovery and the need for additional anti-VEGF in eyes treated by FAc implant. METHODS: The study was designed as prospective and interventional with 1 year of follow-up. We analyzed structural optical coherence tomography (OCT) quantitative biomarkers of inflammation, namely choroidal hyperreflective foci (HF) and the choroidal vascularity index (CVI), and we assessed the relationship with other clinically relevant biomarkers and the outcome achieved after 1 year. Moreover, we stratified DME eyes in good and poor responders to FAc implant to highlight clinically relevant differences. RESULTS: Our study included 50 eyes (50 patients) treated by FAc implant. We found significant best-corrected visual acuity (BCVA) and central macular thickness (CMT) improvements after 1 year. Good responders started with worse visual acuity and higher CMT than poor responders, but gained letters significantly at the end of the follow-up, whereas poor responders showed stable BCVA values. Good responders were characterized by significantly higher choroidal HF and lower CVI than poor responders. Poor responders required significantly higher additional anti-VEGF treatments. CONCLUSIONS: Quantitative structural OCT biomarkers of inflammation allowed distinguishing different inflammatory profiles of DME. The inflammatory component helped to categorize DME eyes in good and poor responders to FAc implant.

Ocular Features and Associated Systemic Findings in SARS-CoV-2 Infection.

PURPOSES: To describe the prevalence of ocular features among COVID-19 patients and their relationship with clinical data, inflammatory markers and respiratory support therapy (including CPAP); to investigate SARS-CoV-2 in ocular secretions of symptomatic patients. METHODS: 172 COVID-19 patients were evaluated for presence of ocular manifestations. Clinical and laboratory data were also reviewed. Conjunctival swabs were analyzed for SARS-CoV-2 by RT-PCR. RESULTS: Forty-five patients (26.2%) reported ocular manifestations. Patients treated with CPAP were more likely to have ocular abnormalities (p <.01). The presence of ocular symptoms was not associated with more significant alterations on blood tests. Conjunctival swabs from patients with suspect conjunctivitis yielded negative results for SARS-CoV-2. CONCLUSIONS: Ocular features are not infrequent in COVID-19 patients, but the presence of SARS-CoV-2 in ocular secretions is low. Ocular manifestations in hospitalized COVID-19 patients can also be a consequence of respiratory support therapy. Prevention of possible transmission through ocular secretions is still recommended.

Persistent or Recurrent Diabetic Macular Edema After Fluocinolone Acetonide 0.19 mg Implant: Risk Factors and Management.

PURPOSE: To investigate baseline characteristics of patients undergoing additional antivascular endothelial growth factor (VEGF) injections for residual or recurrent diabetic macular edema (DME) in the first year after 0.19-mg fluocinolone acetonide (FAc) implant. DESIGN: Prospective cohort study. METHODS: Ninety-four eyes of 66 patients received an FAc implant. Eyes with persistent or recurrent DME were managed with pro re nata anti-VEGF agents. Demographic data and medical history were collected at baseline. Best-corrected visual acuity and central macular thickness were measured every 2 months. The 3 outcomes explored were 1) the risk factors for administration of additional anti-VEGF agents, 2) the interval from FAc to first anti-VEGF injection; and 3) the number of anti-VEGF doses required to maintain regression of DME. RESULTS: Eighteen eyes (19.1%) of 13 patients received 1.3 ± 0.6 anti-VEGF injections. These eyes had significantly thicker central macular thickness at baseline and over the entire follow-up period (P < .001); best-corrected visual acuity was similar at every time point to eyes that were not receiving extra DME treatments. Eyes without preexistent panretinal photocoagulation (PRP) had a higher risk to undergo supplemental treatments (hazard ratio 1.5 [95% confidence interval 1.1-2.5, P = .03). The interval between FAc implant and the first anti-VEGF had a significant linear positive relationship with the number of dexamethasone implants before FAc implant (P = .002, R2 = 0.47). No association was found between baseline factors and the number of injections given. CONCLUSION: Anti-VEGF agents are efficient treatment to maintain visual acuity in residual/recurrent DME after FAc. Patients with higher baseline central macular thickness and with no previous central macular thickness are more likely to require additional treatments to control DME.

HYPERREFLECTIVE FOVEAL SPOTS IN PATIENTS WITH VITREORETINAL ANOMALIES: A Qualitative and Quantitative Analysis.

PURPOSE: To describe structural optical coherence tomography (OCT) and OCT angiography features in patients who have developed hyperreflective foveal spots with or without vitreomacular interface abnormalities or with vitreous adhesion alone. METHODS: The study design was observational and cross sectional. The presence of defined epiretinal membrane was considered an exclusion criterion. All patients underwent complete ophthalmologic examination, with structural OCT and OCT angiography acquisitions. Both qualitative and quantitative analyses of OCT angiography reconstructions were performed for superficial capillary plexus, deep capillary plexus, and choriocapillaris. RESULTS: Thirty patients (20 men; mean age, 55.2 years) showing hyperreflective foveal spots on structural OCT and 30 healthy control subjects (20 men; mean age, 54.7 years) were enrolled. Best-corrected visual acuity was 0.0 ± 0.0 logarithm of the minimum angle of resolution (20/20 Snellen) for both patients and control subjects. Following global and parafoveal/extrafoveal analyses, both superficial capillary plexus and deep capillary plexus showed significant reduction (P < 0.001). Significant superficial capillary plexus and deep capillary plexus changes were also detected in contralateral eyes (P < 0.001). CONCLUSION: Hyperreflective foveal spots might be seen as the initial effect of traction forces causing Müller cell and external retinal layer disruption, leading to the onset of vitreomacular disease. These changes also have an effect on the retinal vascular network. Further larger prospective studies are necessary to confirm our findings.

Quantitative changes in the ageing choriocapillaris as measured by swept source optical coherence tomography angiography.

AIM: To analyse quantitative optical coherence tomography angiography (OCTA) parameters of choriocapillaris (CC) at the foveal, perifoveal and parafoveal regions in healthy subjects of different age. METHODS: In this observational cross-sectional study, consecutive healthy subjects underwent swept source OCTA (PLEX Elite 9000, Carl Zeiss Meditec, USA). 3×3 mm and 6×6 mm scans centred on the fovea were acquired analysed and postprocessed with thresholding and binarisation processes. The main outcome measures included CC quantitative OCTA features (perfusion density (PD), vessel length density (VLD) and vessel diameter index (VDI)) at the foveal, perifoveal and parafoveal regions, and their relationship with age. RESULTS: Seventy-two eyes (72 patients, mean age 47.4±19.2 years, mean axial length 24.0±0.7 mm) were included. The mean PD was statistically lower in the foveal region compared with the parafoveal region in 3×3 mm scans (p=0.009). In subjects aged 70-80, PD of the foveal region was significantly reduced compared with the perifoveal region in 6×6 mm scans (p=0.008). A strong negative correlation was found between PD and ageing in the foveal, parafoveal and perifoveal regions (p<0.001 in all analyses). Furthermore, PD in the nasal-perifoveal region was significantly lower than the temporal-perifoveal region (p=0.005). No significant correlation was found between VLD and age in all regions, whereas VDI was strictly correlated with age (p<0.001). CONCLUSIONS: We reported in vivo a strong negative correlation between PD and ageing in the CC of healthy subjects. This reduction seems related to a reduced diameter, and not to a reduced number, of capillaries. The age-related changes were higher in the central area compared with the perifoveal area.

Advanced Optical Coherence Tomography Angiography Analysis of Age-related Macular Degeneration Complicated by Onset of Unilateral Choroidal Neovascularization.

PURPOSE: To analyze optical coherence tomography angiography (OCTA) quantitative features in patients affected by new-onset choroidal neovascularization (CNV) in 1 eye and early/intermediate age-related macular degeneration (AMD) in the fellow eye. DESIGN: Case-control study. METHODS: Setting: Clinical practice. STUDY POPULATION: Thirty patients and 30 age-matched controls. OBSERVATION PROCEDURES: Both cohorts underwent complete ophthalmologic examination, including best-corrected visual acuity (BCVA) measurement, biomicroscopy, fluorescein angiography (FA) and indocyanine green angiography (ICGA) examination, optical coherence tomography, and OCTA scans. The 1-way a test with Bonferroni correction was used to assess statistical significance and Tau Kendall's correlation analysis was performed. MAIN OUTCOME MEASURES: BCVA, choroidal thickness, vessel density, vessel tortuosity, vessel dispersion. and vessel rarefaction. RESULTS: Mean BCVA was 20/32 for CNV eyes and 20/20 for both fellow and control eyes. Choroidal thickness was 190.33 ± 63.98 µm for CNV eyes, 216.83 ± 50.31 µm for fellow eyes, and 310.52 ± 27.13 µm for controls. The quantitative analysis of retinal vessels revealed significant alterations, especially in the deep capillary plexus and radial peripapillary capillaries, both in CNV and in fellow eyes, compared with controls. In particular, decreased vessel density and tortuosity and increased dispersion and rarefaction were found. Several significant correlations were also found among the quantitative parameters adopted. CONCLUSIONS: New postprocessing OCTA parameters are able to detect deep retinal vascular alterations quantitatively, in both CNV-affected and fellow eyes of patients with new-onset CNV. Further investigations are warranted in order to explore the validity of these new approaches on follow-up.
