Abstract
Background/Objectives: To investigate changes in visual acuity and retinal sensitivity and thickness after intravitreal ranibizumab injection (IRI) for macular edema in branch retinal vein occlusion (BRVO) patients. Methods: This study evaluated 34 patients with treatment-naïve BRVO and at least 6 months' follow-up after pro re nata IRI. Best-corrected visual acuity (BCVA) was determined as the logarithm of the minimum angle of resolution (logMAR). In nine retinal regions, retinal sensitivity was calculated by MP-3 microperimetry; and in nine macular subfields, retinal thickness was measured by optical coherence tomography (OCT); evaluations were performed before IRI and then monthly for 6 months. Results: IRI significantly improved visual acuity and retinal sensitivity and thickness. In patients with good improvement in BCVA (change in logMAR > 0.2), IRI significantly improved retinal sensitivity in eight of nine regions, i.e., in all except the outer non-occluded region, and in patients with poor improvement in BCVA (change in logMAR < 0.2), in six of nine regions, i.e., not in the inner, outer non-occluded, and outer temporal regions. We found significant differences in the trend profile in the foveal, outer occluded, and inner nasal regions between patients with good and poor improvement in BCVA. Conclusions: The findings suggest that IRI improves visual acuity and retinal sensitivity and thickness and that retinal effects may vary between patients with good and poor visual improvement.

Abstract
PURPOSE This study aimed to evaluate anterior flare intensity (AFI) after intravitreal injection of brolucizumab (IVBr) in patients with diabetic macular edema (DME), and to identify the factors associated with the change of AFI after IVBr. METHODS This prospective multicenter study was conducted at five sites in Japan for patients with DME who underwent a single IVBr. AFI and central retinal thickness (CRT) were measured using a laser flare meter and spectral-domain optical coherence tomography, respectively, at weeks 0 and 6. RESULTS Sixty-five patients (phakia, 37 eyes; pseudophakia, 28 eyes) were enrolled. Six weeks after IVBr, CRT and best-corrected visual acuity significantly improved (p < 0.0001). AFI (p = 0.0003) and age (p = 0.0054) were significantly higher in patients with pseudophakic eyes than those with phakic eyes. The AFI of the phakic eyes decreased after IVBr (p = 0.043). As the AFI before injection is higher (p = 0.0363) and the age is lower (p = 0.0016), the AFI decreases after IVBr. There was a significant positive correlation between the rates of change in CRT and AFI (p = 0.024). CONCLUSION After IVBr, AFI decreases in phakic eyes but not in pseudophakic eyes. The age, AFI and CRT before injection and changes of CRT are involved in the change in AFI after IVBr.

Abstract
Background and Objectives: To investigate associations among the aqueous humor levels of novel inflammatory factors, including FMS-related tyrosine kinase 3 ligand (Flt-3L), fractalkine, CXC chemokine ligand 16 (CXCL-16), and endocan-1; the severity of macular edema in central retinal vein occlusion (CRVO); and the prognosis of CRVO with macular edema after antivascular endothelial growth factor (VEGF) therapy. Materials and Methods: Aqueous humor was obtained during anti-VEGF treatment with intravitreal ranibizumab injection (IRI) in patients with CRVO and macular edema (n = 19) and during cataract surgery in patients with cataracts (controls, n = 20), and the levels of VEGF and novel inflammatory factors were measured. Macular edema was evaluated by central macular thickness (CMT) and neurosensory retinal thickness (TNeuro), and improvement was evaluated by calculating the percentage change in CMT and TNeuro from before to 1 month after IRI. Results: The levels of VEGF and the novel inflammatory factors were significantly higher in the CRVO group, and the levels of Flt-3L, CXCL-16, and endocan-1 were significantly correlated with each other and with the aqueous flare value. Baseline levels of Flt-3L, CXCL-16, and endocan-1 had a significantly negative correlation with the change in CMT, and the baseline level of CXCL-16 was significantly negatively correlated with the change in TNeuro. Conclusions: Relations among novel inflammatory factors should be further investigated. These findings may help improve understanding of macular edema in CRVO patients and aid the development of new treatments targeting novel inflammatory factors.

Abstract
Purpose In branch retinal vein occlusion (BRVO), administering steroid injections to inhibit expression of inflammatory factors in the first phase of macular edema may reduce recurrence of the edema. The purpose of our study was to investigate the functional and morphological prognosis and frequency of recurrence after injection of an anti-vascular endothelial growth factor (VEGF) with and without initial steroid therapy to treat macular edema with BRVO. Patients and Methods Patients with BRVO and macular edema (41 eyes) received intravitreal ranibizumab injection (IRI) alone (IRI group, 21 eyes) or subtenon triamcinolone (STTA) injection and IRI (combination group, 20 eyes). Patients in both groups with recurrent macular edema received further IRI as appropriate. A laser flare meter was used to assess aqueous flare values, and an optical coherence tomography device was used to measure central macular thickness (CMT). Before the first treatment, we obtained samples of aqueous humor and analyzed them by the suspension array method to evaluate VEGF, placental growth factor (PlGF), platelet-derived growth factor (PDGF)-AA, soluble intercellular adhesion molecule (sICAM)-1, monocyte chemoattractant protein 1 (MCP-1), interleukin (IL)-6, IL-8, and interferon-inducible 10-kDa protein (IP-10). Results The two groups were not significantly different with regard to levels of VEGF, PlGF, PDGF-AA, sICAM-1, MCP-1, IL-6, IL-8, or IP-10. Best-corrected visual acuity, CMT, and aqueous flare value (IRI group, baseline 8.69 ± 4.55 photon counts/ms; combination group, baseline 9.21 ± 3.72 photon counts/ms) improved significantly in both groups without significant intergroup differences. Analyses showed no significant intergroup differences in the mean number of IRIs during the 12-month follow-up, but the proportion of patients without recurrence (ie, who received only one IRI) was significantly higher in the combination group than in the IRI group (P = 0.032). Furthermore, the time to initial recurrence was significantly longer in the combination group than in the IRI group (P = 0.003). Conclusion These findings suggest that initial STTA injection and IRI may have a synergistic effect in patients with BRVO and macular edema in that they increase the time between anti-VEGF treatments.

Abstract
INTRODUCTION Little research has examined the effects of anti-vascular endothelial growth factor therapy on subfoveal choroidal thickness (SCT), choroidal blood flow, aqueous flare, and humor levels of growth and inflammatory factors in patients with macular edema due to central retinal vein occlusion (CRVO). METHODS In 58 patients with macular edema due to CRVO treated by intravitreal ranibizumab injection (IRI), we retrospectively assessed best-corrected visual acuity (BCVA, assessed as the logarithm of the minimum angle of resolution [logMAR]), 8 aqueous factors (by suspension array), mean blur rate (MBR; estimated by laser speckle flowgraphy as a measure of choroidal blood flow), aqueous flare (with a laser flare meter), and SCT and central macular thickness (CMT; by optical coherence tomography). RESULTS After 4 weeks, IRI resulted in a significant improvement in BCVA and CMT and a significant reduction in SCT, choroidal MBR, and aqueous flare. SCT was significantly positively correlated with placental growth factor and significantly negatively correlated with platelet-derived growth factor-AA, and change in SCT was significantly negatively correlated with change in BCVA (logMAR). Aqueous flare was significantly negatively correlated with SCT. CONCLUSION Growth and inflammatory factors may be associated with SCT, and changes in SCT may be associated with changes in BCVA after IRI to treat macular edema due to CRVO.

Abstract
Background and Objectives: To investigate peripheral blood flow in retinal vessels and vessel diameters after intravitreal ranibizumab injection (IRI) and the relationship between these parameters and cytokines in branch retinal vein occlusion (BRVO) with macular edema. Materials and Methods: We assessed relative flow volume (RFV) and the width of the main and branch retinal arteries and veins in the occluded and non-occluded regions before and after IRI in 37 patients with BRVO and macular edema. Measurements were made using laser speckle flowgraphy (LSFG). When performing IRI, we obtained samples of aqueous humor and analyzed them using the suspension array method to evaluate vascular endothelial growth factor (VEGF), placental growth factor (PlGF), platelet-derived growth factor (PDGF)-AA, soluble intercellular adhesion molecule (sICAM)-1, monocyte chemoattractant protein 1 (MCP-1), interleukin (IL)-6, IL-8, and interferon-inducible 10-kDa protein (IP-10). Results: In both retinal regions, before and after IRI, the RFV in the main artery and vein showed a significant correlation with the summed RFV in the respective branch vessels 1 and 2. In the occluded region, the RFV in the main vein was significantly negatively correlated with MCP-1, PDGF-AA, IL-6, and IL-8; the RFV in branch vein 1 was significantly negatively correlated with PlGF, MCP-1, IL-6, and IL-8; PDGF-AA was significantly negatively correlated with the width of the main and branch veins; and the RFVs of the main artery and vein decreased significantly from before to 1 month after IRI. Conclusions: Contrary to expectations, the study found that anti-VEGF therapy does not affect RFV in arteries and veins in patients with BRVO and macular edema. Furthermore, retinal blood flow is poor in patients with high MCP-1, IL-6, and IL-8. Finally, high PDGF-AA may result in smaller venous diameters and reduced retinal blood flow.

Abstract
We evaluated the long-term (24-month) efficacy of a novel individualized treatment protocol with 2 mg aflibercept for treatment-naive BRVO with macular edema. Each patient received an initial aflibercept injection and was then examined every 2 weeks until recurrence of edema. At recurrence, each patient received a second injection of aflibercept. The period of efficacy was defined as the time between the first and second injections. Subsequently, each patient was examined and re-injected with aflibercept at their personalized treatment interval, which was defined as 1 week shorter than the period of efficacy. Thirty-seven eyes of 48 patients showed recurrence after the initial injection. The mean period of efficacy was 92.5 ± 40.8 days, and the mean number of visits before recurrence, 7.6 ± 2.9. The mean 24-month best corrected visual acuity (BCVA) was significantly better than the mean baseline BCVA but significantly worse than the best BCVA during the period of efficacy. The mean gain of BCVA at 24 months was 0.07 ± 0.18 logMAR. The mean 24-month central macular thickness (CMT) was significantly lower than the mean baseline CMT but showed no difference from the mean best CMT (p = 0.060). The mean total number of visits during the 24 months was 15.8 ± 3.4. We conclude that the individualized treatment protocol that was based on the period of efficacy in treatment-naïve BRVO eyes with macular edema achieved satisfactory long-term visual outcome.

Abstract
Objective We report the 2-year visual and psychological outcomes of the MERCURY study, examining the long-term effectiveness and safety of ranibizumab and subsequent therapy in Japanese patients with diabetic macular oedema with impaired visual acuity (VA) in the real-world setting. Methods and analysis This was a 24-month, phase 4, open-label, single-arm, multicentre, prospective, observational study. Following an initial dose of ranibizumab (0.5 mg) by intravitreal injection (0.05 mL), treatment was administered as needed after month 1. The primary treated eye (PTE) was the first eye that received a ranibizumab injection. Results In total, 209 patients were enrolled; 192 (91.9%) and 174 (83.3%) completed months 12 and 24, respectively. In the PTE set, mean±SD changes in best-corrected VA (BCVA) from baseline to months 12 (primary endpoint) and 24 were −0.08±0.35 (p=0.015) and −0.13±0.30 (p<0.001) logarithmic minimum angle of resolution, respectively. Mean±SD central subfoveal thickness (CSFT) changes from baseline to months 12 and 24 were −102.3±146.1 µm (p<0.001) and −103.6±157.2 µm (p<0.001), respectively. Patients receiving three injections during the first 2 months had greater BCVA improvements throughout the study than those receiving 1–2 consecutive injections. Overall, 91 (43.5%) and 130 (62.2%) patients had ocular and non-ocular adverse events, respectively. At month 24, the mean±SD Hospital Anxiety and Depression Scale (HADS)-Anxiety and HADS-Depression scores decreased by 0.44±3.75 (p=0.196) and 0.19±3.38 (p=0.541), respectively. Conclusions At 24 months after initiation of ranibizumab and subsequent treatment, patients showed significant BCVA and CSFT improvements. Long-term treatment was considered safe and tolerable and did not lead to worsened psychological status.

Abstract
Diabetic macular edema (DME) induces visual disturbance, and intravitreal injections of anti-vascular endothelial growth factor (VEGF) drugs are the accepted first-line treatment. We investigate its impact on glycemic control after starting VEGF treatment for DME on the basis of a questionnaire and changes in hemoglobin A1c (HbA1c). We conducted a retrospective multicenter study analyzing 112 patients with DME who underwent anti-VEGF therapy and their changes in HbA1c over two years. Central retinal thickness and visual acuity significantly improved at three months and throughout the period after initiating therapy (p < 0.0001); a significant change in HbA1c was not found. A total of 59.8% of patients became more active in glycemic control through exercise and diet therapy after initiating therapy, resulting in a significantly lower HbA1c at 6 (p = 0.0047), 12 (p = 0.0003), and 18 (p = 0.0117) months compared to patients who did not. HbA1c was significantly lower after 18 months in patients who stated that anti-VEGF drugs were expensive (p = 0.0354). The initiation of anti-VEGF therapy for DME affects HbA1c levels in relation to more aggressive glycemic control.

Abstract
Background Patients with central retinal vein occlusion (CRVO) and macular edema often are treated by intravitreal ranibizumab injection (IRI). The role of changes in macular sensitivity in the positive effects of IRI on visual functions is unclear. Therefore, we assessed the relationship between macular sensitivity and improvement of visual functions. Methods We included 15 eyes of 15 patients with treatment-naïve CRVO and followed patients for 6 months after pro re nata IRI. IRI was repeated if the central macular thickness was greater than or equal to 300 µm. Microperimetry-3 was used to measure macular sensitivity within the central 1-mm, 3-mm, and 6-mm fields before and monthly for 6 months after IRI. Results IRI significantly improved mean macular sensitivity over time within the central 1-mm, 3-mm, and 6-mm fields (all P < 0.001). None of the fields showed significant differences in the change of mean macular sensitivity between patients with little improvement in best corrected visual acuity (BCVA; i.e., in patients with a change in logarithm of the minimum angle of resolution [logMAR] BCVA < 0.3) and those with marked improvement in BCVA (change in logMAR BCVA > 0.3). The mean macular sensitivity before IRI showed correlations with the improvement of macular sensitivity in every field. Conclusion These findings suggest that IRI improves macular sensitivity in patients with CRVO and macular edema independent of any improvement in BCVA and that macular sensitivity before treatment is associated with improvement of macular sensitivity after treatment.

Abstract
Aims/Introduction In older patients, the management of diabetic macular edema (DME) can be complicated by comorbidities, geriatric syndrome, and socioeconomic status. This study aims to evaluate the effects of aging on the management of DME. Materials and Methods This is a real‐world clinical study including 1,552 patients with treatment‐naïve center‐involved DME. The patients were categorized into 4 categories by age at baseline (C1, <55; C2, 55–64; C3, 65–74; and C4, ≥75 years). The outcomes were the change in logarithm of the minimum angle of resolution best‐corrected visual acuity (logMAR BCVA) and central retinal thickness (CRT), and the number of treatments from baseline to 2 years. Results From baseline to 2 years, the mean changes in logMAR BCVA from baseline to 2 years were −0.01 in C1, −0.06 in C2, −0.07 in C3, and 0.01 in C4 (P = 0.016), and the mean changes in CRT were −136.2 μm in C1, −108.8 μm in C2, −100.6 μm in C3, and −89.5 μm in C4 (P = 0.008). Treatments applied in the 2 year period exhibited decreasing trends with increasing age category on the number of intravitreal injections of anti‐VEGF agents (P = 0.06), selecting local corticosteroid injection (P = 0.031), vitrectomy (P < 0.001), and laser photocoagulation outside the great vascular arcade (P < 0.001). Conclusions Compared with younger patients with DME, patients with DME aged ≥75 years showed less frequent treatment, a lower BCVA gain, and a smaller CRT decrease. The management and visual outcome in older patients with DME would be unsatisfactory in real‐world clinical practice.

Abstract
PURPOSE To examine possible associations between subfoveal choroidal thickness (SCT), choroidal blood flow, aqueous flare value, and aqueous humor levels of multiple growth factors, cytokines, and other inflammatory mediators in patients with branch retinal vein occlusion and macular edema who received antivascular endothelial growth factor (anti-VEGF) therapy. METHODS We recruited 65 patients with macular edema due to branch retinal vein occlusion who received intravitreal ranibizumab injection and measured aqueous levels of eight factors by the suspension array method. Furthermore, we evaluated choroidal blood flows by laser speckle flowgraphy and quantified them as the mean blur rate and measured aqueous flare values using a laser flare meter and SCT and central macular thickness by optical coherence tomography. RESULTS At 1 month after intravitreal ranibizumab injection, central macular thickness was significantly improved and SCT, choroidal mean blur rate, and aqueous flare value were significantly decreased. SCT was significantly correlated with vascular endothelial growth factor and placental growth factor, and the change in both SCT and central macular thickness was significantly correlated with the change in aqueous flare value. However, only SCT was significantly negatively correlated with the aqueous flare value. CONCLUSION Growth factors seem to play a role in SCT. In macular edema with branch retinal vein occlusion, antivascular endothelial growth factor agents may decrease SCT by reducing inflammation.

Abstract
Purpose To report on the safety and effectiveness of intravitreal aflibercept (IVT-AFL) for macular edema secondary to central retinal vein occlusion (CRVO) in clinical practice in Japan. Patients and Methods This prospective, noninterventional, multicenter post-authorization safety study enrolled patients who were treated with IVT-AFL for macular edema secondary to CRVO and followed up for 24 months. The primary outcome was the occurrence of safety events. Other pre-specified outcomes were indicators of effectiveness, including best corrected visual acuity (BCVA), central retinal thickness (CRT), and frequency of injections. Results The safety analysis included 377 patients who received at least one IVT-AFL. Adverse events (AEs) occurred in 22 patients (5.84%) and adverse drug reactions occurred in 5 (1.33%) over 24 months. Of the 22 patients with AEs, 72.7% experienced their first AEs by the third injection. The effectiveness analysis set comprised 360 patients for whom data on each outcome could be collected. The number of injections over 24 months was 3.4 ± 2.4 (mean ± standard deviation [SD]). BCVA (logarithm of the minimum angle of resolution) was 0.709 ± 0.535 (mean ± SD) (n = 357) at baseline and 0.543 ± 0.559 (n = 97) after 24 months of treatment with IVT-AFL. CRT was 552.6 ± 211.3 μm (mean ± SD) (n = 214) at baseline and 331.5 ± 144.0 μm (n = 54) at 24 months. Conclusion There were no new safety issues concerning routine administration of IVT-AFL for macular edema secondary to CRVO. BCVA recovered during 24 months of IVT-AFL treatment in the real-world setting. However, there was a trend toward less improvement compared with the results of randomized controlled trials, likely due in part to undertreatment.

Abstract
Purpose:
The role of inflammation and cytokines in AMD and anti-Vascular Endothelial Growth Factor (anti-VEGF) treatment remains unclear. Therefore, this study aimed to examine whether anti-VEGF treatment for exudative Age-related Macular Degeneration (AMD) affects aqueous flare value (an indicator of inflammation), functional-morphologic parameters, and aqueous humor levels of cytokines or inflammatory mediators.
Methods:
We compared aqueous humor levels of 8 cytokines, growth factors (including VEGF), and inflammatory mediators in 43 patients who received anti-VEGF treatment with aflibercept for AMD and 24 healthy controls by the suspension array method. In addition, we measured aqueous flare values with a laser flare meter and Central Macular Thickness (CMT) and Macular Volume (MV) by optical coherence tomography.
Results:
The patient group had a significantly higher aqueous flare value than the control group. At baseline, CMT showed significant correlations with aqueous humor levels of soluble intercellular adhesion molecule-1 (sICAM-1), monocyte chemoattractant protein 1 (MCP-1), interleukin (IL)-6, and IL-8 and MV, with aqueous humor levels of VEGF, sICAM-1, MCP-1, IL-6, and IL-8. Moreover, we found significant correlations between aqueous flare value and aqueous humor levels of MCP-1, IL-6, IL-8, and interferon-gamma–inducible protein 10. One month after anti-VEGF treatment, the patient group showed a significant correlation between the change in MV and improvement in best-corrected visual acuity (BCVA); CMT showed no such correlation.
Conclusion:
Inflammation appears to be involved in AMD. Change in MV may be an index of improvement in BCVA in patients receiving anti-VEGF treatment for AMD.

Abstract
PURPOSE The MERCURY study aimed to evaluate the effects on visual acuity and psychological symptoms, and safety, of ranibizumab and subsequent treatment in patients with diabetic macular oedema (DME) and impaired visual acuity (VA). We report data from the prespecified 12-month interim analysis. METHODS This was a 24-month, phase 4, open-label, single-arm, prospective, observational study conducted at 20 specialised retinal centres in Japan. Participants were 209 patients with DME and impaired VA, not previously treated with either intravitreal or systemic anti-vascular endothelial growth factor (anti-VEGF) agents, who initiated ranibizumab 0.5 mg per investigator discretion. Following ranibizumab administration, patients were treated per routine clinical practice. Other treatments were allowed. The main outcome measure was the mean change in best-corrected VA (BCVA) in logarithmic minimum angle of resolution (logMAR) from baseline to month 12. An exploratory objective was to assess patients' psychological status using the Hospital Anxiety and Depression Scale (HADS). RESULTS The mean ± standard deviation BCVA at baseline was 0.43 ± 0.39 logMAR. The mean number of injections of ranibizumab and anti-VEGF agents from baseline to month 11 was 3.2 ± 2.0 and 3.6 ± 2.4, respectively. The BCVA change from baseline to 12 months was - 0.08 ± 0.34 logMAR (p = 0.011), showing a significant improvement; the HADS-anxiety score also decreased significantly (p = 0.001) and the depression score decreased numerically (p = 0.080). CONCLUSION MERCURY study data confirm the effectiveness of real-world treatment initiated with ranibizumab in Japanese patients with DME. In addition, treatment was able to positively influence anxiety via VA improvement.

Abstract
INTRODUCTION To investigate the relationship between retinal blood flow and the presence or absence of macular edema (ME) recurrence after intravitreal ranibizumab injection (IRI) in patients with central retinal vein occlusion (CRVO). METHODS We reviewed the medical records of 16 eyes with ME associated with CRVO. All eyes had received pro re nata IRI. Repeat IRI was performed if the central macular thickness was ≥300 µm. At 12 months, patients without additional IRI in the past 6 months were assigned to the resolved group, and those with additional IRI, to the recurrence group. We used laser speckle flowgraphy (LSFG) to measure the mean blur rate (MBR) of the optic disc before and after IRI. RESULTS Ten of the 16 eyes were assigned to the resolved group, and the other 6 eyes to the recurrence group. At several visits in the 12 months after IRI, MBR was significantly higher in the resolved group than in the recurrence group. Percent change of MBR (%Δ MBR) from baseline was significantly higher in the resolved group than in the recurrence group at 1 month (initial %Δ MBR) and 11 and 12 months. Multivariate stepwise analysis showed that the initial %Δ MBR was significantly and negatively correlated with the number of IRIs. DISCUSSION/CONCLUSION These findings suggest that determining %Δ MBR in LSFG may be a useful way to determine the likelihood of ME recurrence in CRVO patients.

Abstract
Objective To evaluate the effectiveness, treatment patterns and long-term safety of ranibizumab 0.5 mg in treatment-naïve patients with central retinal vein occlusion (CRVO) in a real-world setting. Methods LUMINOUS, a 5-year, global, prospective, multicentre, multi-indication, observational, open-label study, recruited treatment naïve or prior treated patients who were treated as per the local ranibizumab label. Here, we report the mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters), treatment exposure over year (Y) 1 and 5-year safety in treatment-naïve CRVO patients. Results At baseline, the mean age of treatment-naïve CRVO patients (n = 327) was 68.9 years, with a mean (Standard deviation [SD]) VA of 40.6 (23.9) letters. At Y1, patients (n = 144) had a mean (SD) VA gain from baseline of 10.8 (19.66) letters, with a mean (SD) of 5.4 (2.65) ranibizumab injections. Patients demonstrated mean (SD) VA gains of 2.7 (19.35), 11.6 (20.56), 13.9 (18.08), 11.1 (18.46) and 8.2 (24.86) letters with 1, 2–3, 4–5, 6–8 and >8 ranibizumab injections, respectively. Mean (SD) VA gains at Y1 in patients receiving loading (67.4%) and no loading dose (32.6%) was 11.9 (20.42) and 8.4 (17.99) letters, respectively. Over five years, the incidence of ocular/non-ocular adverse events (AEs) and serious AEs was 11.3%/8.6% and 1.2%/6.7%, respectively. Conclusions These results demonstrate the effectiveness of ranibizumab in treatment-naïve CRVO patients at Y1 with clinically meaningful VA gains and no new safety findings over five years. These findings may help inform routine practice and enable better clinical management to achieve optimal visual outcomes.

Abstract
Many studies have demonstrated that rhegmatogenous retinal detachment (RRD) leads to impaired retinal circulation. However, the involvement of inflammation in the RRD-induced worsening of retinal circulation was obscure. This retrospective observational study included 150 patients with primary RRD (macula-on, n = 63; macula-off, n = 87) who underwent 25-gauge microincision vitrectomy surgery (25G MIVS). Total retinal blood flow was represented by the mean blur rate (MBR) of the optic nerve head vessel, measured by laser speckle flowgraphy preoperatively and until 6 months postoperatively. Aqueous humor samples were obtained during surgery to determine cytokine concentrations by enzyme-linked immunosorbent assay. At 3 and 6 months postoperatively, there were no significant differences between eyes with macula-on RRD and fellow eyes. However, in macula-off RRD, MBR remained significantly lower in RRD eyes 6 months postoperatively (P < 0.05). Log-transformed levels of soluble intercellular adhesion molecule-1 (sICAM-1) were negatively correlated with relative MBR (r-MBR, RRD eye/fellow eye) before surgery (r = − 0.47, P = 0.01) in macula-on, but not macula-off, RRD. Six months postoperatively, r-MBR correlated significantly with sICAM-1 levels (r = − 0.36, P = 0.02) in macula-off RRD. ICAM-1 may play a role in RRD-induced deterioration of retinal circulation.

Abstract
We investigated the relationship between aqueous cytokine levels, changes in ocular blood flow, and morphological and functional improvements after intravitreal ranibizumab injection (IRI) in treatment-naïve eyes with center-involving diabetic macular edema (DME). Thirty-three eligible patients with DME (33 eyes) were recruited. At the first IRI, we collected a sample of aqueous humor from each eye and measured levels of the cytokines/chemokines. Mean blur rate (MBR) was used to evaluate retinal and choroidal flow by laser speckle flowgraphy at the time of the first IRI and 1 month later. One month after IRI, both retinal and choroidal MBR had significantly decreased from baseline. The reduction ratio of the retinal MBR was significantly correlated with aqueous levels of monocyte chemotactic protein (MCP)-1 and interleukin-8, and with reduction of central macular thickness, but not with improvement of best corrected visual acuity. The reduction ratio of choroidal MBR showed no statistical correlation with any cytokine levels or changes in clinical parameters. We conclude that IRI reduces both retinal and choroidal blood flow in treatment-naïve DME. Reduction of retinal blood flow correlated with regression of morphological pathology, which is regulated by the initial aqueous levels of some cytokines.

Abstract
Background We evaluated the relationship between retinal blood flow and aqueous humor levels of cytokines/growth factors in patients with central retinal vein occlusion (CRVO). Methods In an observational study, 64 eyes of 64 CRVO patients were examined before anti-vascular endothelial growth factor (VEGF) therapy. Blood flow was assessed in large vessels around and at the optic disk by determining the mean blur rate using laser speckle flowgraphy. Aqueous humor samples were obtained from the patients during anti-VEGF therapy and levels of the following molecules were measured by the suspension array method: soluble VEGF receptor (sVEGFR)-1, sVEGFR-2, VEGF, plancental growth factor (PlGF), platelet-derived growth factor (PDGF)-AA, soluble intercellular adhesion molecule (sICAM)-1, monocyte chemotactic protein (MCP)-1, interleukin (IL)-6, IL-8, IL-12(p70), and IL-13. Results The mean blur rate of the affected eye was significantly lower than that of the unaffected eye. The mean blur rate showed a significant negative correlation with the log-transformed aqueous humor levels of PlGF, sICAM-1, and IL-8, but not VEGF. Conclusions These findings suggest that retinal blood flow velocity might be more strongly correlated with inflammatory factors than VEGF in patients with nonischemic CRVO and macular edema.

Abstract
PURPOSE Correlations among the aqueous flare value (an indicator of inflammation), several functional-morphologic parameters, and aqueous humor levels of multiple cytokines or inflammatory factors were investigated in patients with diabetic macular edema (DME) receiving intravitreal rani-bizumab injection (IRI). METHODS Aqueous humor levels of 12 cytokines, growth factors, or inflammatory factors were measured in 46 DME patients who received IRI. Vascular endothelial growth factor (VEGF), soluble VEGF receptor (sVEGFR), and the other cytokines/inflammatory factors were measured by the suspension array method. In addition, aqueous flare values were measured with a laser flare meter, and central macular thickness (CMT) was examined by optical coherence tomography. RESULTS At 1 month after IRI therapy, the aqueous flare value showed a significant decrease compared with before treatment (baseline). Significant correlations were noted between the aqueous flare value and the aqueous humor levels of 6 factors/cytokines, including sVEGFR-1, placental growth factor, monocyte chemoattractant protein 1, soluble intercellular adhesion molecule-1, interleukin (IL)-6, and interferon-inducible 10-kDa protein (IP-10). There was also a significant correlation between the change in aqueous flare value and improvement in CMT 1 month after IRI. CONCLUSIONS These findings suggest that IRI reduces subclinical inflammation and that the aqueous flare value is influenced by inflammatory factors/cytokines. In addition, the change in the aqueous flare value may be an indicator of the response of CMT to IRI in patients with DME.

Abstract
Background/aims To investigate the yearly change of real-world outcomes for best corrected visual acuity (BCVA) after 2-year clinical intervention for treatment-naïve diabetic macular oedema (DMO). Methods Retrospective analysis of aggregated, longitudinal medical records obtained from 27 retina specialised institutions in Japan from Survey of Treatment for DMO database. A total of 2049 treatment-naïve centre involving DMO eyes of which the initial intervention started between 2010 and 2015, and had been followed for 2 years, were eligible. As interventions, antivascular endothelial growth factor (VEGF) agents, local corticosteroids, macular photocoagulation and vitrectomy were defined. In each eye, baseline and final BCVA, the number of each intervention for 2 years was extracted. Each eye was classified by starting year of interventional treatment. Results Although baseline BCVA did not change by year, 2-year improvement of BCVA had been increased, and reached to +6.5 letters in the latest term. There is little difference among starting year about proportions of eyes which BCVA gained >15 letters, in contrast to those which lost >15 letters were decreased by year. The proportion of eyes receiving anti-VEGF therapy was dramatically increased, while those receiving the other therapies were gradually decreased. The proportion of eyes which maintained socially good vision of BCVA>20/40 has been increased and reached to 59.0% in the latest term. Conclusion For recent years, treatment patterns for DMO have been gradually but certainly changed; as a result, better visual gain, suppression of worsened eyes and better final BCVA have been obtained. Anti-VEGF therapy has become the first-line therapy and its injection frequency has been increasing.

Abstract
Background/Aims To investigate real-world outcomes for best-corrected visual acuity (BCVA) after 2-year clinical intervention for treatment-naïve, centr-involving diabetic macular oedema (DME). Methods Retrospective analysis of longitudinal medical records obtained from 27 institutions specialising in retinal diseases in Japan. A total of 2049 eyes with treatment-naïve DME commencing intervention between 2010 and 2015 who were followed for 2 years were eligible. Interventions for DME included anti-vascular endothelial growth factor (VEGF) therapy, local corticosteroid therapy, macular photocoagulation and vitrectomy. Baseline and final BCVA (logMAR) were assessed. Eyes were classified by the treatment pattern, depending on whether anti-VEGF therapy was used, into an anti-VEGF monotherapy group (group A), a combination therapy group (group B) and a group without anti-VEGF therapy (group C). Results The mean 2-year improvement of BCVA was −0.04±0.40 and final BCVA of >20/40 was obtained in 46.3% of eyes. Based on the treatment pattern, there were 427 eyes (20.9%) in group A, 807 eyes (39.4%) in group B and 815 eyes (39.8%) in group C. Mean improvement of BCVA was −0.09±0.39, –0.02±0.40 and −0.05±0.39, and the percentage of eyes with final BCVA of >20/40 was 49.4%, 38.9%, and 52.0%, respectively. Conclusion Following 2-year real-world management of treatment-naïve DME in Japan, BCVA improved by 2 letters. Eyes treated by anti-VEGF monotherapy showed a better visual prognosis than eyes receiving combination therapy. Despite treatment for DME being selected by specialists in consideration of medical and social factors, a satisfactory visual prognosis was not obtained, but final BCVA remained >20/40 in half of all eyes.

Abstract
PURPOSE To investigate the relations of vascular endothelial growth factor, growth factors, soluble vascular endothelial growth factor receptors, and inflammatory factors to recurrence of macular edema after anti-vascular endothelial growth factor therapy in patients with branch retinal vein occlusion. METHODS This study retrospectively investigated 17 patients with branch retinal vein occlusion who received intravitreal ranibizumab injection three times within 6 months for recurrent macular edema. Aqueous humor samples were obtained from these patients at every recurrence. Levels of soluble vascular endothelial growth factor receptor-1, soluble vascular endothelial growth factor receptor-2, vascular endothelial growth factor, placental growth factor, platelet-derived growth factor-AA, soluble intercellular adhesion molecule-1, monocyte chemoattractant protein-1, interleukin-6, interleukin-8, interleukin-12(p70), and interleukin-13 were measured by the suspension array method. Aqueous flare values were measured with a laser flare meter and central macular thickness was determined by optical coherence tomography. RESULTS Mean best-corrected visual acuity and central macular thickness improved significantly over time after intravitreal ranibizumab injection, but the aqueous flare value at recurrence after intravitreal ranibizumab injection showed no significant change compared with baseline. Aqueous humor levels of soluble vascular endothelial growth factor receptor-1, soluble vascular endothelial growth factor receptor-2, vascular endothelial growth factor, platelet-derived growth factor-AA, monocyte chemoattractant protein-1, and interleukin-8 decreased significantly over time after intravitreal ranibizumab injection. However, there were no significant changes of the other five factors/cytokines (placental growth factor, soluble intercellular adhesion molecule-1, interleukin-6, interleukin-12, and interleukin-13) at recurrence after intravitreal ranibizumab injection compared with baseline. CONCLUSION These findings suggest that persistent inflammation may influence the recurrence of macular edema in branch retinal vein occlusion patients, and that adding steroid therapy might be an effective strategy for preventing recurrence.

Abstract
PURPOSE To evaluate real-world evidence for young Japanese patients with rhegmatogenous retinal detachment (RRD) by retrospectively examining surgical procedures and clinical outcomes in the Japan Clinical Retina Study group. METHODS This was a multicentre retrospective study of the medical records of 562 young patients (384 males and 178 females; mean age: 33.0 ± 11.8 years) who had been diagnosed with RRD and who underwent surgical procedures in participating centres during the period between April 2013 and August 2016. RESULTS The selected surgeries were scleral buckling (SB) for 295 eyes (49.7%) and pars plana vitrectomy (PPV) for 262 eyes (44.1%). Between the two surgical procedures, there was no significant difference in the primary anatomical reattachment rate (PARR, SB = 92.2%, PPV = 93.9%); improvements in vision were noted in both groups. The incidences of proliferative vitreoretinopathy and cataract formation within 1 year of PPV were 2.3% (p = 0.0047) and 6.5% (p = 0.0005), whereas they were 0% and 1.0% in the SB group, respectively. CONCLUSION Scleral buckling (SB) and PPV were chosen with almost equal frequency for young patients with RRD. Clinical outcomes for SB and PPV exhibited a similar PARR. The incidence of cataract formation after PPV may constitute an important limitation of the procedure.

Abstract
Background Correlations among the aqueous flare value (an indicator of inflammation), functional-morphologic parameters, and aqueous humor levels of growth factors/receptors and inflammatory factors/cytokines were investigated in patients with central retinal vein occlusion (CRVO) and macular edema who received intravitreal ranibizumab injection (IRI) and were followed for 6 months. Methods Aqueous humor levels of 11 cytokines or growth inflammatory/factors were measured in 20 CRVO patients with macular edema receiving IRI. Patients with recurrent macular edema were administered further IRI as needed. Aqueous humor levels of vascular endothelial growth factor (VEGF), soluble VEGF receptor (sVEGFR), and other cytokines/inflammatory factors were measured by the suspension array method. Aqueous flare values were measured with a laser flare meter and macular edema was examined by optical coherence tomography. Results Compared with before treatment (baseline), the aqueous flare value showed a significant decrease at both 1 month and 6 months after IRI therapy. There were significant correlations between the aqueous flare value and the aqueous levels of sVEGFR-1, placental growth factor, monocyte chemoattractant protein 1, soluble intercellular adhesion molecule-1, interleukin (IL)-6, and IL-8. In addition, a significant correlation was noted between the change of the aqueous flare value and improvement of central macular thickness at 6 months after IRI, as well as a significant correlation between the change of the aqueous flare value and improvement of best-corrected visual acuity at 6 months. Conclusions These findings suggest that IRI reduces inflammation and that the aqueous flare value is influenced by inflammatory factors/cytokines. In addition, the change of the aqueous flare value may be an indicator of the long-term prognosis in CRVO patients receiving IRI therapy for macular edema.

Abstract
AIMS/INTRODUCTION To determine the current clinical preferences of anti-vascular endothelial growth factor (VEGF) treatment protocols for diabetic macular edema (DME) in Japan. MATERIALS AND METHODS This was a descriptive cross-sectional study. Answers to a questionnaire consisting of 16 questions were obtained from 176 of 278 (63.3%) surveyed ophthalmologists. RESULTS The results showed that 81.2% preferred intravitreal injections of anti-VEGF antibodies as the first-line therapy. The most important indicators for beginning anti-VEGF therapy were: the best-corrected visual acuity in 44.3% and the retinal thickness in 30.7%. In the loading phase, 53.4% preferred a single injection, and in the maintenance phase, 75.0% preferred the pro re nata regimen. Financial limitation (85.8%) was reported as the most important difficulty in the treatment. For combination therapy with anti-VEGF treatment, panretinal photocoagulation, focal photocoagulations and a sub-Tenon steroid injection were preferred. The contraindications for anti-VEGF therapy were: prior cerebral infarction (72.7%). Regarding the use of both approved anti-VEGF agents in Japan, ranibizumab and aflibercept, 39.8% doctors used them appropriately. CONCLUSIONS Our results present the current clinical preferences of anti-VEGF treatment for DME in Japan. The best-corrected visual acuity and the retinal thickness are important indicators to institute this therapy. The majority of the ophthalmologists use anti-VEGF treatment as first-line therapy and prefer the 1 + pro re nata regimen.

Abstract
Background Intravitreal ranibizumab injection (IRI) is effective for patients with exudative age-related macular degeneration (AMD) and decreases intraocular levels of vascular endothelial growth factor (VEGF), but VEGF receptor intraocular dynamics after IRI are unclear. Therefore, we evaluated changes in the aqueous humor levels of soluble vascular endothelial growth factor receptor (sVEGFR)-1, sVEGFR-2, and their ligands for these receptors (VEGF) patients with AMD receiving IRI. Methods The subjects were 24 patients with AMD (24 eyes) who received 3 doses of IRI at monthly intervals. Aqueous humor samples were obtained when each IRI dose was given (visits 0, 1, and 2 at 4-week intervals). Then the suspension array method was employed to measure sVEGFR-1, sVEGFR-2, VEGF, and placental growth factor (PlGF) in aqueous humor samples from the 24 AMD patients and 13 cataract patients (as controls). Best corrected visual acuity (BCVA; logMAR) chart and central macular thickness (CMT; optical coherence tomography) were also assessed over time. Results At baseline, the aqueous humor levels of sVEGFR-1, sVEGFR-2, VEGF, and PlGF were significantly higher in the AMD group than in the control group. There was a significant correlation between VEGF and PlGF or between sVEGFR-1 and sVEGFR-2. BCVA and CMT both improved significantly after IRI, and the aqueous humor levels of VEGF, PlGF, and sVEGFR-1 also decreased significantly. Conclusions VEGFRs may be involved in the pathogenesis of AMD. IRI improves clinical parameters in AMD patients by suppressing intraocular levels of VEGF, PlGF, and sVEGFR-1.

Abstract
Leber hereditary optic neuropathy (LHON) is a mitochondrial disorder predominantly affecting young men. Characteristic features of an early stage of LHON are peripapillary telangiectatic microangiopathy with optic disc hyperaemia and swelling of the retinal nerve fibre layers. We evaluated the microcirculation of the optic nerve head (ONH) by laser speckle flowgraphy (LSFG) in a 79-year-old man and a 36-year-old woman with LHON. The ONH microcirculation of the tissue area was markedly increased in the early stage in both patients. LSFG may be a useful noninvasive method to suspect individuals to have an early stage of LHON.

Abstract
PURPOSE To compare aqueous humor levels of various cytokines between patients with age-related macular degeneration (AMD) and cataract patients. METHODS Thirteen eyes with wet-type AMD (AMD group) and 14 eyes with cataract (cataract group) were studied. Aqueous humor levels of 11 factors (vascular endothelial growth factor receptors, growth factors, and inflammatory factors) were measured by the suspension array method. RESULTS Aqueous humor levels of vascular endothelial growth factor, soluble vascular endothelial growth factor receptor (sVEGFR)-1, sVEGFR-2, and inflammatory factors (monocyte chemotactic protein (MCP)-1, interleukin (IL)-6, and IL-8) were significantly higher in the AMD group than in the cataract group (all p < 0.05). In contrast, aqueous humor levels of placental growth factor (PGF), tumor necrosis factor-α, soluble intercellular adhesion molecule (sICAM)-1, IL-12 (p70), and IL-13 showed no significant difference between the two groups. There were significant correlations between sVEGFR-1 or sVEGFR-2 levels and some of the inflammatory molecules (PGF, sICAM-1, MCP-1, IL-6, and IL-8). CONCLUSIONS These findings suggest that various cytokines/growth factors involved in inflammation and angiogenesis may be associated with the pathogenesis of AMD.

Abstract
PURPOSE To investigate dynamic changes in aqueous humor levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), and inflammatory factors in patients receiving intravitreal ranibizumab injection (IRI) or intravitreal aflibercept injection (IAI) to treat central retinal vein occlusion (CRVO) with macular edema. METHODS In 22 CRVO patients scheduled to receive 3 doses of ranibizumab (11 eyes) or aflibercept (11 eyes) at monthly intervals, aqueous samples were collected at the time of intravitreal injection. The concentrations of VEGF, PlGF, soluble intercellular adhesion molecule-1, monocyte chemotactic protein (MCP)-1 (CCL2), platelet-derived growth factor-AA, interleukin (IL)-6, IL-8 (CXCL8), IL-12(p70) (IL12B), and IL-13 in aqueous samples were measured by the suspension array method. RESULTS Visual acuity and foveal thickness improved significantly in both the IRI group and the IAI group. In addition, aqueous levels of VEGF and PlGF as well as MCP-1 and IL-6 decreased significantly over time in both groups. These parameters did not significantly differ between both groups. CONCLUSIONS In CRVO patients, both ranibizumab and aflibercept achieved similar improvement in clinical parameters and similar reductions in aqueous VEGF, PlGF, MCP-1, and IL-6 levels.

Background/Aims To investigate whether intravitreal injection of triamcinolone acetonide (IVTA) combined with vitrectomy prevents postoperative inflammation in patients with vitreous haemorrhage (VH) due to proliferative diabetic retinopathy (PDR). Methods This prospective, multicentre, randomised study conducted at seven sites in Japan enrolled patients diagnosed as having VH following PDR. Patients underwent vitrectomy with (IVTA+VIT group) or without (VIT group) IVTA at the end of the surgery. Anterior flare intensity (AFI), central retinal thickness (CRT), best-corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured before and at 3 days, 1 week, 1, 3 and 6 months after surgery and compared. Results Number of patients who completed 6 months of follow-up was 40 and 41 in VIT group and IVTA+VIT group, respectively. AFI was significantly higher in the VIT group than in the IVTA+VIT group at 3 days (P=0.033), 1 week (P=0.019) and 1 month (P=0.037). There were no significant differences in CRT, BCVA and IOP between the groups through the observational periods. In the cases with macular oedema >350 µm of CRT at 3 days, CRT was significantly lower in the IVTA+VIT group than in the VIT group at 1 month (P=0.041). Conclusions IVTA combined with vitrectomy and cataract surgery contributed to inhibit the postoperative inflammation in patients with VH due to PDR. The effect of IVTA in the reduction of diabetic macular oedema may be limited to the early stage after surgery. Trial registration number UMIN000020376, Post-results.

Abstract
BACKGROUND Anatomical knowledge of the duodenojejunal flexure is necessary for abdominal surgeries, and also important for physiologic studies about the duodenum. But little is known about the anatomy of this region in mammals. Here, we examined comparative anatomy to understand the anatomical formation of the duodenojejunal flexure in mammals. MATERIALS AND METHODS The areas around the duonenojejunal flexure were ob-served in mouse, rat, dog, pig, and human, and the anatomical structures around the duodenojejunal junction in the animals were compared with those in human. RESULTS The superior and inferior duodenal folds, and the superior and inferior duodenal fossae were identified in all examined humans. In pig, the structures were not clearly identified because the duodenum strongly adhered to the retroperitoneum and to the mesocolon. In mouse, rat, and dog, only the plica duodenocolica, which is regarded as the animal counterpart of the superior duo-denal fold in human, was identified, and other folds or fossae were not observed, probably because the duodenum was not fixed to the parietal peritoneum in those animals. Transection of the plica duodenocolica could return the normally rotated intestine back to the state of non-rotation in rat. CONCLUSIONS This study showed the anatomical similarities and dissimilarities of the duodenojejunal flexure among the mammals. Anatomical knowledge of the area is useful for duodenal and pancreatic surgeries, and for animal studies about the duodenum. (Folia Morphol 2018; 77, 2: 286-292).

Abstract
WHAT IS KNOWN AND OBJECTIVE Adaptive design methods are expected to be ethical, reflect real medical practice, increase the likelihood of research and development success and reduce the allocation of patients into ineffective treatment groups by the early termination of clinical trials. However, the comprehensive details regarding which types of clinical trials will include adaptive designs remain unclear. We examined the practical characteristics of adaptive design used in clinical trials. METHODS We conducted a literature search of adaptive design clinical trials published from 2012 to 2015 using PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials, with common search terms related to adaptive design. We systematically assessed the types and characteristics of adaptive designs and disease areas employed in the adaptive design trials. RESULTS AND DISCUSSION Our survey identified 245 adaptive design clinical trials. The number of trials by the publication year increased from 2012 to 2013 and did not greatly change afterwards. The most frequently used adaptive design was group sequential design (n = 222, 90.6%), especially for neoplasm or cardiovascular disease trials. Among the other types of adaptive design, adaptive dose/treatment group selection (n = 21, 8.6%) and adaptive sample-size adjustment (n = 19, 7.8%) were frequently used. The adaptive randomization (n = 8, 3.3%) and adaptive seamless design (n = 6, 2.4%) were less frequent. Adaptive dose/treatment group selection and adaptive sample-size adjustment were frequently used (up to 23%) in "certain infectious and parasitic diseases," "diseases of nervous system," and "mental and behavioural disorders" in comparison with "neoplasms" (<6.6%). For "mental and behavioural disorders," adaptive randomization was used in two trials of eight trials in total (25%). Group sequential design and adaptive sample-size adjustment were used frequently in phase 3 trials or in trials where study phase was not specified, whereas the other types of adaptive designs were used more in phase 2 trials. Approximately 82% (202 of 245 trials) resulted in early termination at the interim analysis. Among the 202 trials, 132 (54% of 245 trials) had fewer randomized patients than initially planned. This result supports the motive to use adaptive design to make study durations shorter and include a smaller number of subjects. WHAT IS NEW AND CONCLUSION We found that adaptive designs have been applied to clinical trials in various therapeutic areas and interventions. The applications were frequently reported in neoplasm or cardiovascular clinical trials. The adaptive dose/treatment group selection and sample-size adjustment are increasingly common, and these adaptations generally follow the Food and Drug Administration's (FDA's) recommendations.

Abstract
PURPOSE To evaluate the dynamic changes of the aqueous humor levels of inflammatory factors between patients receiving intravitreal ranibizumab injection (IRI) and aflibercept injection (IAI) in patients with exudative age-related macular degeneration (AMD). METHODS The study was performed on 30 eyes with AMD that were scheduled to receive 3 doses of IRI (15 eyes) or IAI (15 eyes) at monthly intervals. Aqueous humor samples were collected when injection was done. The concentrations of VEGF, monocyte chemoattractant protein 1 (MCP-1), platelet-derived growth factor (PDGF)-AA, interleukin (IL)-6, and IL-8 were measured in aqueous humor samples from the 30 AMD patients and 10 cataract patients (as controls) by the suspension array method. RESULTS Aqueous levels of the inflammatory factors (MCP-1, PDGF-AA, IL-6, and IL-8) were significantly correlated with each other. In both the IRI-treated eyes and the IAI-treated eyes, visual acuity and central macular thickness improved significantly, and the aqueous level of VEGF showed a significant decrease. In IAI-treated eyes, the aqueous levels of MCP-1 and PDGF-AA were significantly decreased at 2 months. CONCLUSIONS These findings suggest that the inflammatory factors are involved in the pathogenesis of AMD and also the possibility that the interaction between these inflammatory factors and IRI or IAI is different.

Abstract
Aqueous levels of soluble vascular endothelial growth factor receptor (sVEGFR) and inflammatory factors were measured in 35 patients (37 eyes) with diabetic macular edema (DME) receiving anti-vascular endothelial growth factor (VEGF) therapy. Aqueous levels of growth factors (VEGF, placental growth factor [PlGF], and platelet-derived growth factor AA [PDGF-AA]), sVEGFR-1 and -2, soluble intercellular adhesion molecule 1, monocyte chemotactic protein (MCP)-1, interleukin (IL)-6, -8, -12, and -13, and interferon-inducible 10-kDa protein (IP-10) were significantly higher in the DME group than in the nondiabetic control group. The sVEGFR-2 level was significantly correlated with the neurosensory retinal thickness, as well as with the levels of growth factors (VEGF and PDGF-AA) and inflammatory factors (MCP-1, IL-6, and IL-8). Three growth factors (VEGF, PlGF, and PDGF-AA) were also significantly correlated with each other, as were sVEGFR-1 or -2 and the inflammatory factors (MCP-1, IL-6, IL-8, and IP-10). These findings suggest that sVEGFRs and growth/inflammatory factors have an important role in DME.

Abstract
BACKGROUND/AIMS To investigate the relations between aqueous humour levels of cytokines/growth factors and treatment response to intravitreal ranibizumab (IVR) for diabetic macular oedema (DME) METHODS: Sixty-eight eyes of 68 patients with treatment-naïve centre-involved DME, central macular thickness (CMT) greater than 400 μm and visual acuity (VA) worse than logMAR 0.3 were recruited. Each patient received monthly IVR injection (0.5 mg/0.05 mL) until CMT was reduced to below 300 μm. Additional IVR was given to maintain CMT below 300 μm during the clinical course of 6 months with monthly follow-up. Aqueous concentrations of cytokines/chemokines and growth factors were measured using samples obtained just before first IVR injection. CMT and VA were monitored monthly for up to 6 months. The number of monthly IVR injections given during the 6-month study period was also recorded. RESULTS Twenty-four eyes showed CMT <300 μm soon after the first IVR injection (good responders), while 12 eyes did not reach the goal after six consecutive injections (poor responders). Baseline CMT and VA were not significantly different between the two groups. However, the good responders showed significant increases in baseline aqueous concentrations of vascular endothelial growth factor (VEGF), placenta growth factor, soluble VEGF receptor-1 (sVEGFR1), monocyte chemoattractant protein-1, intercellular adhesion molecule-1, interleukin 6 and inducible protein-10, but not of sVEGFR2, compared with poor responders. CONCLUSIONS Response to ranibizumab treatment for DME appears to be associated with aqueous concentrations of VEGFR1 family and certain inflammatory cytokines, but not with clinical parameters.

Abstract
Background A few reports have described ocular complications of influenza A infection, such as impaired ocular movement, parasympathetic ocular nerve, keratitis, macular lesion, and frosted branch angiitis. We encountered a rare case of acute anterior uveitis and optic neuritis associated with influenza A infection. Case presentation A 70-year-old man presented with symptoms of upper respiratory tract infection. A rapid diagnostic test showed a positive result for influenza A. At the same time, he developed ocular symptoms including blurred vision with optic disk edema and hemorrhage in the left eye, and bilateral red eyes. Multiplex polymerase chain reaction performed on aqueous humor sample detected no viral infection. Visual field testing with a Goldmann perimeter showed central and paracentral scotomas in the left eye. In addition to antiviral agent (oseltamivir phosphate 75 mg), the patient was prescribed topical prednisolone acetate ophthalmic suspension eye drops every 5 hours and high-dose intravenous methylprednisolone 1,000 mg daily for 3 days. Two months later, his best-corrected visual acuity improved to 20/50 with regression of visual field defects in his left eye. Conclusion We report a case of bilateral acute anterior uveitis and unilateral optic neuritis concomitant with influenza A infection. Topical and systemic corticosteroids were effective to resolve acute anterior uveitis and neuritis. Analysis of aqueous humor sample suggested that acute anterior uveitis and optic neuritis in this case were not caused by influenza A virus infection per se but by autoimmune mechanism.

Abstract
The aqueous humor levels of cytokines and growth/inflammatory factors were measured in 46 branch retinal vein occlusion (BRVO) patients with macular edema (ME) who were treated with intravitreal ranibizumab injection (IRI). Patients with recurrence of ME received further IRI as needed. The number of IRIs was significantly correlated with age, baseline best-corrected visual acuity, and baseline central macular thickness (CMT), as well as the baseline aqueous levels of 5 cytokines/factors (soluble vascular endothelial growth factor receptor-1, platelet-derived growth factor-AA [PDGF-AA], soluble intercellular adhesion molecule-1, interleukin-6 [IL-6], and IL-8). Multivariate linear regression analysis with stepwise selection confirmed that age, baseline CMT, and baseline PDGF-AA level were independent determinants of the number of IRIs. These findings suggest that inflammatory factors may influence the recurrence of ME in BRVO patients, and that PDGF-AA might be a useful indicator of the number of IRIs required to control ME.

Abstract
BACKGROUND Although intravitreal injection of bevacizumab (IVB) is effective for macular edema in patients with branch retinal vein occlusion (BRVO), the changes of retinal hemodynamics remain unclear. We investigated retinal hemodynamic changes in BRVO patients after IVB by performing laser speckle flowgraphy (LSFG). METHODS In 35 BRVO patients with macular edema, the relative flow volume (RFV) of the retinal artery and vein passing through the optic disc was measured in both the occluded and non-occluded regions of the retina before IVB and 1 month after IVB by LSFG. The ischemic region of retina was measured with the Scion Image program and the severity of retinal ischemia was assessed by dividing the non-perfused area by the disc area. RESULTS Macular edema improved significantly by 1 month after IVB. The venous RFV ratio showed a significant increase in the non-occluded region at 1 month after IVB. There was a significant negative correlation between the venous RFV ratio and the severity of retinal ischemia in the occluded region. On the other hand, arterial RFV ratio showed no significant change after IVB in either the occluded or non-occluded region. In addition, there was no significant correlation between the arterial RFV ratio and the severity of retinal ischemia in either the occluded or non-occluded region. CONCLUSIONS These results suggest that an increase of retinal venous outflow after IVB may possibly influence the resolution of macular edema and that the response of venous outflow after IVB depends on the severity of retinal ischemia in the occluded region.

Abstract
PURPOSE To investigate changes of cytokines after intravitreal anti-vascular endothelial growth factor (VEGF) therapy in patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO). METHODS Monthly doses of intravitreal bevacizumab (IVB) were administered for 6 months to treat macular oedema associated with BRVO or CRVO. Aqueous humour levels of 11 factors were measured using samples obtained from 24 patients during IVB treatment (16 BRVO patients and 8 CRVO patients). Levels of VEGF, placental growth factor (PlGF), soluble VEGF receptor (sVEGFR)-1, sVEGFR-2, soluble intercellular adhesion molecule (sICAM)-1, monocyte chemoattractant protein (MCP)-1, platelet-derived growth factor (PDGF)-AA, interleukin (IL)-6, IL-8, IL-12 (p70), and IL-13 were measured by suspension array. RESULTS Vision and macular oedema improved significantly after monthly IVB. Furthermore, there was a significant decrease in sVEGFR-1, VEGF, PDGF-AA, MCP-1, and IL-8 after monthly IVB. On the other hand, there were no significant changes of sVEGFR-2, PlGF, sICAM-1, or IL-6 after monthly IVB. After 1 dose of bevacizumab, changes of VEGF, visual acuity, and optical coherence tomography parameters almost occurred in parallel. CONCLUSIONS These findings suggest an important role of the cytokine network in both BRVO and CRVO, and may contribute to a new strategy for macular oedema associated with retinal vein occlusion.
