UNASSIGNED: Polypoidal choroidal vasculopathy (PCV) is a hemorrhagic fundus disease that can lead to permanent vision loss. Predicting the treatment response to anti-VEGF monotherapy in PCV is consistently challenging. We aimed to conduct a prospective multicenter study to explore and identify the imaging biomarkers for predicting the anti-VEGF treatment response in PCV patients, establish predictive model, and undergo multicenter validation.
UNASSIGNED: This prospective multicenter study utilized clinical characteristics and images of treatment naïve PCV patients from 15 ophthalmic centers nationwide to screen biomarkers, develop model, and validate its performance. Patients from Peking Union Medical College Hospital were randomly divided into a training set and an internal validation set. A nomogram was established by univariate, LASSO regression, and multivariate regression analysis. Patients from the other 14 centers served as an external test set. Area under the curve (AUC), sensitivity, specificity, and accuracy were calculated. Decision curve analysis (DCA) and clinical impact curve (CIC) were utilized to evaluate the practical utility in clinical decision-making.
UNASSIGNED: The eye distribution for the training set, internal validation set, and external test set were 66, 31, and 71, respectively. The \'Good responder\' exhibited a thinner subfoveal choroidal thickness (SFCT) (230.67 ± 61.96 vs. 314.42 ± 88.00 μm, p < 0.001), lower choroidal vascularity index (CVI) (0.31 ± 0.08 vs. 0.36 ± 0.05, p = 0.006), fewer choroidal vascular hyperpermeability (CVH) (31.0 vs. 62.2%, p = 0.012), and more intraretinal fluid (IRF) (58.6 vs. 29.7%, p = 0.018). SFCT (OR 0.990; 95% CI 0.981-0.999; p = 0.033) and CVI (OR 0.844; 95% CI 0.732-0.971; p = 0.018) were ultimately included as the optimal predictive biomarkers and presented in the form of a nomogram. The model demonstrated AUC of 0.837 (95% CI 0.738-0.936), 0.891 (95% CI 0.765-1.000), and 0.901 (95% CI 0.824-0.978) for predicting \'Good responder\' in the training set, internal validation set, and external test set, respectively, with excellent sensitivity, specificity, and practical utility.
UNASSIGNED: Thinner SFCT and lower CVI can serve as imaging biomarkers for predicting good treatment response to anti-VEGF monotherapy in PCV patients. The nomogram based on these biomarkers exhibited satisfactory performances.

UNASSIGNED: To evaluate the safety, pharmacokinetics, and exploratory efficacy of tivozanib eye drops in healthy volunteers and patients with neovascular age-related macular degeneration (nAMD).
UNASSIGNED: This multicenter group-sequential dose escalation phase I study consisted of a placebo-controlled double-masked study of healthy volunteers (cohorts 1 and 2) and an open-label study of patients with nAMD (cohort 3).
UNASSIGNED: Healthy volunteers: Japanese or White men aged 20 to <50 years. Patients with nAMD with central subfield thickness (CST) ≥300 μm and best-corrected visual acuity score ≥23 letters in the study eye.
UNASSIGNED: In the single-dose cohort of healthy men (cohort 1: steps 1-5), 1 or 2 tivozanib eye drops (30 μL/drop, 5-minute interval; 0.5, 1.0, and 2.0 w/v%) or placebo were administered in 1 eye once. In the multiple-dose cohort of healthy men (cohort 2: steps 1-6), 1 or 2 tivozanib eye drops (0.5, 1.0, and 2.0 w/v%) or placebo were administered 3 times daily in 1 eye for 21 days. In the multiple-dose cohort of patients with nAMD (cohort 3, steps 1-3), 1 or 2 tivozanib eye drops (0.5 and 1.0 w/v%) were administered 3 times daily in 1 affected eye for 21 days.
UNASSIGNED: The safety outcome measures included adverse events (AEs). The pharmacokinetic outcome was serum tivozanib concentration. Among the exploratory efficacy outcomes, CST was evaluated.
UNASSIGNED: In total, 40, 48, and 28 participants were enrolled in cohorts 1, 2, and 3, respectively. Serious AEs did not occur in cohorts 1 to 3. The most frequent AE in multiple-dose cohorts was reversible punctate keratitis: placebo arm, 8.3% (healthy men, 1/12); tivozanib arm, 47.2% (healthy men, 17/36) and 14.3% (nAMD, 4/28). Serum tivozanib exposure increased dose-dependently and was similar in healthy men and patients with nAMD. In patients with nAMD, mean CST changes from baseline to day 22 were -27.6 ± 54.88 (0.5 w/v%; 1 drop, 3 times daily), -35.6 ± 49.64 (1.0 w/v%; 1 drop, 3 times daily), and -43.7 ± 55.19 μm (1.0 w/v%; 2 drops, 3 times daily).
UNASSIGNED: Tivozanib eye drops showed a favorable safety profile in healthy Japanese and White men and Japanese patients with nAMD.

UNASSIGNED: Limited data is available on treatment satisfaction with the management of wet age-related macular degeneration (wAMD) among patients in Italy. In this cross-sectional real-world study, treatment satisfaction with anti-vascular endothelial growth factor (anti-VEGFs) was assessed in patients with wAMD in Italy.
UNASSIGNED: This was a non-interventional, cross-sectional survey involving patients with wAMD receiving anti-VEGFs. The survey was administered through a virtual assistant via phone. Patients\' treatment satisfaction was assessed using a newly developed Novartis Tailored Treatment Satisfaction Questionnaire (NVS TTSQ) and the validated Macular Disease Treatment Satisfaction Questionnaire (MacTSQ).
UNASSIGNED: Overall, 154 evaluable patients were enrolled in 5 centers across Italy. The mean (SD) age of the patients was 76.8 years (7.01). Overall treatment satisfaction score assessed by NVS TTSQ was 40.50 (7.11), with a mean of 9.97 (1.84) on the information domain and 22.98 (4.57) on the unmet need domain. Patients were satisfied with diagnosis communication (4.99 [1.30]), information provided on treatment administration (4.58 [1.49], range 0-6), the waiting room (4.40 [1.43]), and management of visits and injections at the center (5.14 [1.12]), general management of maculopathy at the center (5.22 [1.01]). Patients were not satisfied with their independence in terms of disease management (2.56 [2.45]); they would like additional information about the disease (5.38 [1.03]) and to discuss the injection procedures (4.02 [1.94]) with already-treated patients. The overall treatment satisfaction score on MacTSQ scale was 55.84 (10.13).
UNASSIGNED: Patients with wAMD are satisfied with the overall management of their disease in Italy. However, patients would like to have more information on prognosis and management of the disease.

UNASSIGNED: To evaluate the responses of different optical coherence tomography (OCT) patterns of diabetic macular edema (DME) to intravitreal injection therapy.
UNASSIGNED: In this retrospective, comparative, and multicenter study, patients who had previously untreated DME, who received intravitreal ranibizumab (IVR) or aflibercept (IVA) and/or steroid treatment with the pro re nata (PRN) treatment regimen after a 3-month loading dose, and had a 12-month follow-up in the MARMASIA Study Group were included. Morphological patterns of DME were divided into four groups based on OCT features diffuse/spongious edema (Group 1), cystoid edema (Group 2), diffuse/spongious edema+subretinal fluid (SRF) (Group 3), and cystoid edema+SRF (Group 4). Changes in central macular thickness (CMT) and best-corrected visual acuity (BCVA) at months 3, 6, and 12, and the number of injections at month 12 were compared between the DME groups.
UNASSIGNED: 455 eyes of 299 patients were included in the study. The mean baseline BCVAs [Logarithm of the Minimum Angle of Resolution (logMAR)] in groups 1, 2, 3, and 4 were 0.54 ± 0.24, 0.52 ± 0.25, 0.55 ± 0.23, and 0.57 ± 0.27, respectively. There was no significant difference between the baseline mean BCVAs between the groups (p = .35). The mean BCVAs were significantly improved to 0,47 ± 0,33 in group 1, 0,42 ± 0,33 in group 2, 0,47 ± 0,31 in group 3, and 0,45 ± 0,43 at month 12. There was no significant difference between the groups in terms of BCVA change at month 12 (p = .71). The mean baseline CMTs in groups 1, 2, 3, and 4 were 387,19 ± 128,19, 447,02 ± 132,39, 449,12 ± 109,24, and 544,19 ± 178,61, respectively. At baseline, the mean CMT was significantly higher in Group 4 than in the other groups (p = .000). The mean CMTs were significantly decreased to 325,16 ± 97,55, 334,94 ± 115,99, 324,33 ± 79,20, and 332,08 ± 150,40 in four groups at month 12 respectively (p > .05). The groups had no significant difference in mean CMT at month 12 (p = .835). The change in CMT was significantly higher in Group 4 than in the other groups at month 12 (p = .000). The mean number of intravitreal anti-VEGF injections at month 12 was 4.51 ± 1.57 in Group 1, 4.63 ± 1.54 in Group 2, 4.88 ± 1.38 in Group 3, and 5.07 ± 1.49 in Group 4. The mean number of anti-VEGF injections in Group 1 and Group 2 was significantly lower than in Group 4 (p = 0,014 and p = 0,017).
UNASSIGNED: In real life, there was no significant difference between the DME groups in terms of visual improvement at month 12. However, better anatomical improvement was achieved in Group 4 than in the other DME groups.

Purpose The purpose of this study is to examine the impact of the timing of the steroid switch on both visual and anatomical outcomes in diabetic macular edema (DME) eyes that have shown an inadequate response to multiple intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. In the treatment of DME, anti-VEGF injections are typically the initial course of action. However, in cases where DME persists despite anti-VEGF treatment, intravitreal dexamethasone implants (Ozurdex®, Allergan Inc., Irvine, CA) are often utilized. Despite this, there remains a lack of consensus regarding the optimal timing for transitioning to steroid treatment. This study aims to shed light on the potential benefits of adjusting the timing of the steroid switch in cases of recalcitrant DME.  Methods The eyes (n = 105) of 77 patients with recalcitrant DME were included in this retrospective, interventional, comparative study comprising three groups: participants switched to steroid implants after three anti-VEGF injections (Group I), four to six anti-VEGF injections (Group II), and more than six anti-VEGF injections (Group III). Anti-VEGF treatment failure was defined as a central retinal thickness (CRT) of ≥300 microns and/or a lack of visual improvement (≤1 line of visual gain according to Snellen acuity). The last follow-up took place after 10-12 weeks of Ozurdex® injections. Results Improvement was observed in 19 eyes (46%), 17 eyes (50%), and 10 eyes (33%) in Groups I, II, and III, respectively, after switching to dexamethasone implants. The best overall results (an improvement in vision and stabilization) were seen in Group II (32 eyes, 94%). The decrease in CRT was statistically significant in all three groups.  Conclusion Intravitreal dexamethasone implants improved functional and morphological outcomes in anti-VEGF-resistant DME eyes. After four to six anti-VEGF injections, switching to a steroid implant resulted in the best functional results.

OBJECTIVE: To analyze cardiovascular and cerebrovascular adverse events (ADRs) after intravitreal anti-vascular endothelial growth factor (VEGF; aflibercept, bevacizumab, brolucizumab, and ranibizumab) treatment.
METHODS: VigiBase, a World Health Organization (WHO) global safety report database DESIGN: Pharmacovigilance study METHODS: The individual-case-safety reports (ICSR) of cardiovascular and cerebrovascular ADRs after intravitreal anti-VEGF treatment were compared with those reported in the full database. From 2004 to 2023, 23,129 ADRs after intravitreal anti-VEGF therapy and 25,015,132 ADRs associated with any drug (full database).
METHODS: The reporting odds ratio (ROR) and information components (IC) were calculated, and the 95% lower credibility interval endpoint of the information component (IC025) was used for disproportionate Bayesian reporting. Inter-drug comparisons were performed using the ratio of odd ratio (rOR).
RESULTS: Compared with the full database, anti-VEGFs were associated with an increased reporting of myocardial infarction (IC025 0.75; ROR: 1.78 [95% CI 1.70-1.86]), angina pectoris (IC025 0.53; ROR: 1.61 [95% CI 1.47-1.77]), arrythemias including atrial fibrillation, atrial flutter, ventricular fibrillation, supraventricular tachycardia (all IC025 >0, ROR>1), hypertension (IC025 2.22; ROR: 4.91 [95% CI 4.82-5.01]), and hypertensive crisis (IC025 1.97; ROR: 4.49 [95% CI 4.07-4.97]). Moreover, anti-VEGFs were associated with a higher reporting of cerebrovascular ADRs such as cerebral infarction (IC025 4.34; ROR: 23.19 [95% CI 22.10-24.34]), carotid artery stenosis (IC025 1.85; ROR: 5.24 [95% CI 3.98-6.89]), cerebral hemorrhage (IC025 2.29; ROR: 5.38 [95% CI 5.03-5.76]), and subarachnoid hemorrhage (IC025 1.98; ROR: 4.81 [95% CI 4.14-5.6]). Inter-drug comparison indicated that compared to ranibizumab, patients with aflibercept showed overall under-reporting of cardiovascular and cerebrovascular ADRs such as myocardial infarction (rOR 0.55 [95% CI 0.49-0.52]), atrial fibrillation (rOR 0.28 [95% CI 0.23-0.35]), cerebrovascular accident (rOR, 0.15 [95% CI 0.14-0.17]), and cerebral hemorrhage (rOR, 0.51 [95% CI 0.40-0.65]).
CONCLUSIONS: In this pharmacovigilance case-noncase study, significantly increased reporting of cardiovascular and cerebrovascular ADRs were identified after intravitreal anti-VEGF treatment. While ranibizumab may exhibit superior systemic safety regarding its biological characteristics, it is crucial not to overlook the occurrence of cardiovascular and cerebrovascular ADRs considering its higher reporting rate than bevacizumab or aflibercept.

OBJECTIVE: This study aimed to evaluate the treatment efficacy, anatomical outcomes, and refractive outcomes of laser photocoagulation (LPC) and intravitreal ranibizumab (IVR) in the treatment of type I retinopathy of prematurity (ROP) at one-year follow-up.
METHODS: This is a retrospective study on the treatment of type I ROP and aggressive ROP (A-ROP) using LPC or IVR in three Malaysian hospitals providing pediatric ophthalmology services from January 2019 to December 2021. Information on gestational age, birth weight, ROP zone and stage, and underlying comorbidities was collected. Parameters for evaluating treatment efficacy include the time taken to achieve complete regression, the regression rate, and the reactivation rate. The anatomical and refractive outcomes were evaluated at one year of adjusted age.
RESULTS: This study included 92 eyes from 46 infants. Of these, 42 eyes received LPC as the initial treatment, while 50 eyes underwent IVR. A higher percentage of infants with cardiovascular disease were treated with IVR (66.7%) compared to LPC (40%) (p<0.05). However, there were no significant differences in gestational age, birth weight, respiratory distress syndrome, sepsis, or intraventricular hemorrhage between the two treatment groups (p>0.05). Infants treated with LPC had a higher regression rate than those treated with IVR, but they were also significantly more myopic and had worse best-corrected visual acuity (BCVA). Conversely, infants treated with IVR experienced a significantly higher reactivation rate compared to those treated with LPC. Logistic regression analysis showed no significant associations between gestational age, birth weight, plus disease, zone 1 ROP, and the choice of initial treatment with the reactivation of ROP.
CONCLUSIONS: Both LPC and IVR effectively treat type I ROP in infants, with IVR yielding superior anatomical and refractive outcomes and LPC offering a lower reactivation rate. Understanding individual patient characteristics is crucial for treatment selection.

OBJECTIVE: In this study we investigated the efficacy of short-term intravitreal injections of anti-vascular endothelial growth factors (anti-VEGF) in treating traumatic submacular hemorrhage.
METHODS: A total of 115 patients were diagnosed with submacular hemorrhage between 2018 and 2022 at Shenzhen Eye Hospital. In a retrospective analysis, we examined 13 of these patients who presented with submacular hemorrhage and choroidal rupture due to ocular trauma. Eight patients were treated with intravitreal anti-VEGF injection and 5 with oral drugs. We systematically analyzed changes in their ocular conditions pre and post-treatment. The evaluations encompassed best-corrected visual acuity (BCVA), optical coherence tomography, fundus fluorescein angiography, and retinal imaging.
RESULTS: The 13 patients diagnosed with submacular hemorrhage comprised of 10 males and 3 female, with their age ranging between 27 and 64 years, with an average age of 38.1 years (standard deviation [SD]: 11.27). A statistically significant reduction in central foveal thickness (CFT) was observed following intravitreal injections of anti-VEGF drugs (P = 0.03). In control group, the CFT was reduced without statistical significance (P = 0.10). The BCVA of the patients in treatment group improved significantly from 1.15 (SD: 0.62. Range: 0.4-2) to 0.63 (SD: 0.59. Range: 0.1-1.6), indicating an average increase of 4.13 lines (SD: 3.36. Range: 0-9) as measured by the visual acuity test using an eye chart (P = 0.01). The difference between baseline visual acuity and final visual acuity was not statistically significant in control group (P = 0.51).
CONCLUSIONS: Short-term administration of anti-VEGF drugs exhibited significant efficacy in reducing submacular hemorrhage following ocular trauma and enhancing visual acuity.

OBJECTIVE: The present study tested the hypothesis that repeated anti-VEGF injections are associated with reduced retinal nerve fiber layer (RNFL) and minimum rim width (MRW) of the optic nerve head.
METHODS: Sixty-six patients with a history of intravitreal injections due to neovascular age-related macular degeneration were included. RNFL and MRW were measured using optical coherence tomography (Spectralis OCT, Heidelberg Engineering, Heidelberg, Germany).
RESULTS: Mean global RNFL was 90.62 μm and both RNFL as well as MRW significantly decreased with advanced age (p = 0.005 and p = 0.019, respectively). Correlating for the number of injections, no significant impact on RNFL was found globally (p = 0.642) or in any of the sectors. In contrast, however, global MRW was significantly reduced with increasing numbers of intravitreal injections (p = 0.012). The same holds true when adjusted for the confounding factor age (RNFL p = 0.566 and MRW p = 0.023).
CONCLUSIONS: Our study shows that repeated intravitreal injections due to choroidal neovascularization seem to have a deleterious effect on MRW but not on RNFL. This suggests that MRW is a more sensitive marker than RNFL for evaluating the effect of frequent intravitreal injections on the optic nerve head since it seems to be the first structure affected.

BACKGROUND: Optimizing treatment protocols for wet age-related macular degeneration (wAMD) is an ongoing challenge, as it involves a delicate balance between achieving therapeutic efficacy and minimizing invasive procedures\' frequency. This study aimed to apply the Lean methodology and evaluate the effectiveness of this new setting on intravitreal therapy for wAMD, employing different anti-vascular endothelial growth factors (VEGF) drugs (bevacizumab, brolucizumab, aflibercept, ranibizumab), drawing data from the Bari Intravitreal Injections Registry (BIVIR).
METHODS: This was a retrospective, monocentric, nonrandomized, comparative study. Lean methodology was employed to design the new setting and the BIVIR collected information from electronic medical records. Clinical data of four groups, stratified based on the first-line anti-VEGF agents used, were compared. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) changes were compared between the four groups at 3 and 12 months.
RESULTS: Out of 4990 eyes and 41,323 intravitreal injections (IVs) recorded in BIVIR, 1421 eyes of 1182 patients were included. The mean number of IVs in first year was 6.1 ± 2.5, with no significant differences among the four subgroups. The mean change in BCVA was + 6.2 letters [95% confidence interval (CI) 5.6-6.8] after two IVs, and + 5.9 (95% CI 5.1-6.8) letters after three IVs; at three months, brolucizumab was associated with a greater mean increase in BCVA than bevacizumab (p = 0.050); aflibercept (p = 0.044) and ranibizumab p = 0.047). At the 1-year follow-up, the mean change was + 6.3 letters (95% CI 5.4-7.2), brolucizumab and ranibizumab were associated with a superior improvement in BCVA compared to aflibercept (p = 0.033). Regarding the CRT, a significant reduction was observed in the subgroup treated with brolucizumab at the 3-month follow-up, compared to bevacizumab (p = 0.003), aflibercept (p = 0.015), and ranibizumab (p < 0.001); Aflibercept exhibited a superior effect than ranibizumab (p = 0.001). At 1-year follow-up, aflibercept resulted in a more significant reduction of macular thickness compared to ranibizumab (p = 0.016) while no significant differences were observed among the other drugs.
CONCLUSIONS: Our practical experience showed the effectiveness of the new setting in the treatment of wAMD. This comparative study at 1 year suggested a predominant brolucizumab efficacy on functional outcomes. In addition, brolucizumab and aflibercept appeared to have similar efficacy in fluid control.
