Introduction: There are a few reports investigating the treatment of aneurysmal type 1 neovascularization (AT1) in Caucasian patients. The aim of this study is to evaluate the 2-year results of a treat and extend regimen with aflibercept in Caucasian patients with AT1. Methods: We conducted an observational retrospective study in 28 eyes of 26 patients with naïve AT1 treated with a treat an extend regimen of intravitreal aflibercept. Best corrected visual acuity (BCVA), central macular thickness (CMT), pigment epithelium detachment (PED) height, presence of dry macula, and regression rate of polypoidal lesions were assessed at baseline and at 12 and 24 months. Results: BCVA was significantly increased by 9.03 ± 16 letters ( p < 0.01) and 9.2 ± 16.87 letters ( p < 0.01) after the 12 and 24 months follow-up. A significant decrease of CMT was found at 12 and 24 months ( p < 0.01). Nevertheless, significant changes in PED height were not observed (0.1 <  p > 0.05). At 12 and 24 months of follow-up, dry macula was achieved in a total of 10 eyes (35.71%) and 15 eyes (53.57%). The regression rate of polypoidal lesions was 25% (7 eyes) and 35.71% (10 eyes) after 12 and 24 months. The mean number of intravitreal injections was 7.81 ± 3.20 the first year and 6.11 ± 3.49 the second year. Conclusion: To the best of our knowledge, treat and extend regimen with intravitreal aflibercept in Caucasian patients may be effective for improving BCVA, CMT, wet macula, and regression rate of polypoidal lesions.

AbstractThis prospective, open-label, single-arm, non-randomized clinical trial, assessed the efficacy of a 2-year treat-and-extend (T&E) regimen involving intravitreal aflibercept injection (IAI), with the longest treatment interval set to 16 weeks, and adjunct focal/grid laser in diabetic macula edema (DME) patients. We examined 40 eyes (40 adults) with fovea-involving DME from 8 Japanese centers between April 2015 and February 2017. Participants received IAI with an induction period featuring monthly injections and a subsequent T&E period featuring 8–16-week injection interval, adjusted based on optical coherence tomography findings. The primary endpoints were mean changes in the best-corrected visual acuity (BCVA) and central subfield macular thickness (CST) from baseline. Thirty patients (75%) completed the 2-year follow-up. The mean BCVA and CST changed from 60.5 ± 15.6 letters and 499.2 ± 105.6 µm at baseline to 66.6 ± 17.1 letters (P = 0.217) and 315.2 ± 79.0 µm (P < 0.001), respectively, after 2 years. The treatment interval was extended to 12 and 16 weeks in 6.7% and 66.7% of patients, respectively, at the end of 2 years. The T&E aflibercept regimen with the longest treatment interval set to 16 weeks, with adjunct focal/grid laser may be a rational 2-year treatment strategy for DME.

AbstractThe aim of this observational study was to assess the use and outcome of intravitreal aflibercept in a treat and extend regimen in treatment-naïve neovascular AMD patients in routine practice. This both retrospective and prospective study was conducted in four larger Swiss retina clinics (ASTERIA study). The primary endpoint was the mean change in best-corrected visual acuity (BCVA) in ETDRS letters from baseline to 12 months. Between December 2017 and August 2018, 160 patients were included. For patients with available data, the mean change in BCVA was + 8.4 (± 14.4) letters at month 12 (n = 139) and + 5.0 (± 11.4) letters at month 24 (n = 95). A mean number of 8.3 (± 2.4) injections were administered within the first year and 5.4 (± 2.9) injections during the second year. On average, the observed treatment interval at month 12 was 63.3 (± 22.0) days and increased to 69.1 (± 28.6) days at month 24. For 37% of the patients, a treatment interval ≥ 12 weeks was attained at month 24. In conclusion,  intravitreal aflibercept in a Swiss real-life treat and extend regimen resulted in comparable anatomic and functional outcomes as were observed in the prospective registration trials of aflibercept for nAMD treatment.

Purpose: To report the visual and anatomic outcomes in treatment-naïve neovascular age-related macular degeneration (nAMD) patients treated with aflibercept under a standardized Treat and Extend (T&E) protocol for up to 3 years of follow-up in “real-life” practice. Methods: This retrospective, observational, multicenter study included patients with treatment-naïve nAMD and at least 12 months of follow-up. T&E regimen adjustment was initiated after loading phase. At each visit best-corrected visual acuity (BCVA) and optical coherence tomography parameters were performed. Results: One hundred and thirty-six eyes of 115patients had at least 1 year of follow-up with 114 and 82 eyes completing at least 2 and 3 years of follow-up, respectively (mean follow-up duration: 2.7 ± 1.3 years). Mean age was 78.6 ± 8.6 years old and 52% were women. Mean BCVA increased from 60.6 ± 18.7 letters at diagnosis to 66.9 ± 16.2 letters at 1 year (+6.3 letters, p = 0.003) and remained stable throughout the follow-up period (63.1 ± 20.3 letters (+2.5, p = 0.1) and 64.0 ± 20.1 letters (+3.4, p = 0.27) at 2 and 3 years, respectively). The mean central retinal thickness decreased significantly from 358.2 ± 87.9 µm at baseline to 302 ± 71.7 µm at 12 months and maintained stable after 36 months of follow-up (297.1 ± 76 µm, p < 0.0001). Mean number of injections was 6.6 ± 2.2, 4.8 ± 1.9, and 5.6 ± 1.7 at 1, 2, and 3 years, respectively. Mean cumulative number of 16.4 ± 5.6 injections after 3 years. Mean treatment interval was 6.8 ± 2.5 weeks at 1 year. Eight-week and 12-week treatment interval were achieved in 59.5% and 19.1%, 65.8%, and 36.8% and 69.5% and 41.5% at 1, 2, and 3 years, respectively. Conclusions: Our study demonstrated that intravitreal injections of aflibercept initiated under a standardized T&E for patients with treatment-naïve nAMD allow for significant visual improvement at 12 months, which was maintained over a 3-year follow-up period.

AbstractBackground:Hereditary tyrosinemia type 1 (HT1) is a rare, inborn error of tyrosine metabolism. It is a fatal disorder without treatment. Early treatment may prevent acute liver failure, renal dysfunction, liver cirrhosis, hepatocellular carcinoma (HCC) and improves survival. The aim of the present study is to describe the clinical, biochemical, imaging and follow-up of seven patients with HT1 and to define the consequences of the late and interrupted treatment.Methods:A retrospective study was carried out with seven HT1 patients.Results:The median age at onset of clinical symptoms was 11.2 months (range, 3–28 months) and the median age at diagnosis was 22 months (range, 6–58 months). Liver enzymes and coagulation parameters were back to normal in all symptomatic patients in about 2 weeks. Alfa-fetoprotein (AFP) levels were normalized within the first year of therapy. Hypoechoic nodule formation was detected in two of the seven patients despite drug treatment without an increase of AFP and any dysplastic changes in the biopsies. One patient died due to metastatic HCC because of the late diagnosis and the poor compliance of the follow-up.Conclusions:This study showed once again that adherence to the treatment and a follow-up schedule of the patients are very important. Also it should not be forgotten that nodule formation can occur despite nitisinone treatment without an increase of AFP. Despite nitisinone treatment, HT1 patients still carry the risk of HCC. HCC must be detected before metastasis to other organs otherwise, patients may lose the chance for liver transplantation.

Purpose. To compare the visual and anatomic outcomes in patients with persistent diabetic macular edema (DME) who switched from ranibizumab to aflibercept with those who continued with previous ranibizumab therapy. Methods. In this retrospective comparative study, medical records of consecutive patients with center-involved DME ≥ 350 μm who had at least three recent consecutive monthly ranibizumab injections followed by as-needed therapy with either aflibercept or ranibizumab were reviewed. Data were collected at presentation (preinjection), at the intermediary visit, and at the last visit (at the end of the follow-up period). Results. Forty-three eyes of 43 patients were divided into two groups: the switch group (n=20) and the ranibizumab group (n=23). Though no significant improvement was found in the mean BCVA from the intermediary visit to the last visit, there was a difference in the mean CMT in the switch group and the ranibizumab group (p<0.001 and p=0.03, resp.). The mean CMT decreased after the intermediary visit by 188.6 ± 120.5 μm in the switch group and by 60.3 ± 117.1 μm in the ranibizumab group (p=0.003). Conclusions. Both aflibercept and ranibizumab decreased CMT in patients with persistent DME who showed a poor response to ranibizumab injections. However, switching to aflibercept provided only morphologic improvement.

Fifty-four subjects (36 females and 18 males) affected by clinically definite multiple sclerosis (MS) and with onset of the disease at 15 years of age or before were prospectively studied in five Italian MS centres. Female/male ratio was 4.7 in subjects with age ≥12 years, suggesting a role of hormonal changes in triggering MS onset. The mean follow-up duration was 10.9-5.6 years. The functional systems more frequently involved at onset were the pyramidal and brainstem (both in 28% of cases). The onset was monosymptomatic in 31 subjects (57%). The course was relapsing-remitting in 39 subjects (72%) and relapsing-progressive in 15 (28%). Disability was assessed by the Expanded Disability Status Scale (EDSS): the mean score after 8 years of follow up was 3.5 (-2.5). The score was <4 in 68% of cases, between 4 and 6 in 8% of cases, > 6 in 24% of cases. Disability after 8 years was highly predicted by disability in the first year (p=0.008). There was a tendency to a worse prognosis in relation to the number of relapses in the first 2 years (p=0.08). The outcome was not influenced by the characteristics of symptoms at onset, age and gender.

Background/aimsTo evaluate the time needed for patients with Boston type 1 keratoprosthesis (KPro) to reach their best-corrected visual acuity (BCVA) and all contributing factors.MethodsWe retrospectively reviewed 137 consecutive eyes from 118 patients, measured how long they needed to reach their BCVA and looked at factors that might affect this time duration including patient demographics, ocular comorbidities and postoperative complications.ResultsThe mean follow-up was 5.49 years. The median time to BCVA postoperatively was 6 months, with 47% of patients achieving their BCVA by 3 months. The mean best achieved logMAR visual acuity was 0.71, representing a gain of 6 lines on the Snellen visual acuity chart. Postoperative glaucoma, retroprosthetic membrane (RPM) and endophthalmitis prolonged this duration. We found no correlation between the following factors and time to BCVA: gender, age, indication for KPro surgery, primary versus secondary KPro, number of previous penetrating keratoplasties, previous retinal surgery, intraoperative anterior vitrectomy and preoperative glaucoma.ConclusionIn our retrospective cohort, the majority of subjects reached their BCVA between 3 and 6 months after KPro implantation. This duration was significantly prolonged by the development of postoperative glaucoma, RPM and endophthalmitis.

AimTo characterise macular neovascularisation (MNV) developing in eyes affected by geographic atrophy (GA).MethodsIn this multicentric longitudinal study involving three retina referral centres, patients previously affected by GA who developed an active MNV were included. Patients were investigated using structural optical coherence tomography (OCT), fundus autofluorescence, OCT-angiography and dye angiographies. Patients were treated with ProReNata antivascular endothelial growth factor (VEGF) injections and were revaluated after treatment.ResultsAmong 512 patients previously diagnosed with GA, 40 eyes of 40 patients (mean age 80.8±7.9 years, mean GA area 8.73±7.39 mm2) presented with treatment-naïve exudative MNV (accounting for an estimated prevalence of 7.81%; 5.49 to 10.13, 95% CIs) and thus were included in the analysis. 67.5% of MNVs were classified as type 2 MNV, 25% as type 1, 2.5% as type 3 and 5% as mixed phenotype. In 92.5% of cases, active MNV in GA showed subretinal hyperreflective material with or without evidence of subretinal/intraretinal hyporeflective exudation. During a mean follow-up of 28±25 months, patients were treated with 6.6±6.3 anti-VEGF injections, with 2.9±1.4 injections in the first year of treatment. No patient developed GA enlargement in the area of MNV.ConclusionsMNVs in GA showed different features and therapeutic response in comparison to previously reported features of MNV in age-related macular degeneration (AMD) without GA. For these reasons, the combined phenotype (ie, GA with neovascular AMD) should be considered as a distinct entity in the research and clinical setting.

Abstract Purpose: To compare the effect of intravitreal ranibizumab (IVR) or intravitreal dexamethasone implants (IVD) on regression of hyperreflective dots (HRDs) on optical coherence tomography (OCT) B-scan in patients with branch retinal vein occlusion (BRVO). Methods: 37 eyes of 37 patients with cystoid macular edema who received IVR or IVD and followed up for at least 12 months were included in this study. The patients were divided into three groups according to intravitreal treatment. Group 1 consisted of 12 eyes who received only IVD, group 2 consisted of 10 eyes who received only IVR on a pro re nata and group 3 consisted of 15 eyes who received both IVD and IVR. OCT parameters (CMT, number of HRDs, status of external limiting membrane (ELM) and ellipsoid zone (EZ)) and best-corrected visual acuity (BCVA) were compared between the groups over the follow-up time. HRDs were categorized as HRD in inner retinal layers (from the internal limiting membrane to the inner nuclear layer) or HRD in outer retinal layers (from the outer plexiform layer to the outer border of the photoreceptor layer).Results: There was no significant difference between groups in terms of BCVA, CMT, HRDs in the inner and the outer retinal layers at baseline visit. (p˃0.05 for all) Comparing the baseline values in all groups, a significant decrease was observed in CMT in the first year. (For group 1; p=0.013, group 2; p=0.010; group 3, p<0.001) The BCVA was significantly increased after 1 year in all groups. (p=0.001, p=0.006, p<0.001) The mean number of HRDs in inner and outer retinal layers were significantly decreased in group 1 and group 3. (For group 1; p<0.001, p=0.001, for group 3; p<0.001, p<0.001) However, there was no significant difference in terms of the mean number of HRDs in inner and outer retinal layers for group 2. (p=0.134, p=0.477) At the first year, the number of HRDs in inner and outer retinal layers was significantly lower in group 1 and group 3 than group 2. (For inner HRDs; group 1 vs. group 2 p=0.007, group 2 vs. group 3 p<0.001. For outer HRDs group 1 vs. group 2 p<0.001, group 2 vs. group 3 p<0.001.) The BCVA was higher in group 3 than group 2 at 1year. (p=0.048). There was no significant difference in terms of post-treatment CMT and the number of HRDs between group 1 and group3 in posthoc tests (p=0.621, p=0.876, and p=0.632).Conclusion: The reduction in HRDs at 12 months and better BCVA after IVD intimates that the HRDs should be considered as inflammatory markers in the follow-up of CME in BRVO. Thus, IVD injection could be more appropriate for patients with higher HRDs after BRVO.
