Perioperative and Postoperative Continuous Nutritional Counseling Improves Quality of Life of Gastric Cancer Patient Undergoing Gastrectomy.

Post-gastrectomy syndrome (PGS) and body weight loss (BWL) decrease quality of life (QOL) and survival of the patient undergoing gastrectomy. We have introduced perioperative and post-discharge continuous nutritional counseling (CNC) to prevent BWL and improve QOL after gastrectomy. In the present study, we evaluated the effect of CNC on QOL using the Post-gastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Eighty-three patients with gastric cancer (GC) who underwent curative gastrectomy between March 2018 and July 2019 were retrospectively analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 45) or CNC (CNC group, n = 38) after gastrectomy. QOL at 12 months after gastrectomy was compared between the two groups. In QOL assessment, change in body weight (-7.98% vs. -12.77%, p = 0.0057), ingested amount of food per meal (7.00 vs. 6.07, p = 0.042) and ability for working (1.89 vs. 2.36, p = 0.049) were significantly better in CNC group than control group. Multiple regression analysis showed that CNC was a significantly beneficial factor for abdominal pain subscale (p = 0.028), diarrhea subscale (p = 0.047), ingested amount of food per meal (p = 0.012), Ability for working (p = 0.031) and dissatisfaction at the meal (p = 0.047). Perioperative and postoperative CNC could improve QOL in the patient undergoing gastrectomy in addition to preventing postoperative BWL.

Association Between Pancreatic Cysts and Diabetes Mellitus in Von Hippel-Lindau Disease.

INTRODUCTION: Pancreatic cysts are frequently observed in patients with von Hippel-Lindau disease (VHL), and they are considered clinically not important. This study aimed to evaluate the association between pancreatic cysts and diabetes mellitus (DM) in patients with VHL. METHODS: Among patients who were on a patient list at the VHL Center at Kyoto University Hospital as of December 2022, those who had undergone an upper abdominal magnetic resonance imaging study after 2010 were retrospectively evaluated. The presence or absence of DM and high glycated hemoglobin (HbA1c) levels (>6.0%) were assessed. Patients were divided into two groups: those with DM or high HbA1c levels, and those without DM or high HbA1c levels. The area of the whole pancreas, including the pancreatic cysts and tumors, the area of the pancreatic cysts, and the percentage of pancreatic cysts, calculated by dividing the area of pancreatic cysts by the area of the whole pancreas, were measured on T2-weighted magnetic resonance images and compared between the two groups. RESULTS: Thirty-six patients with VHL, comprising 22 men and 14 women, with a mean age of 36.4 years (range, 11-79 years), were identified. Seven patients had DM, and two additional patients had high HbA1c levels. The area of the pancreatic cysts (p = 0.0013) was significantly larger and the percentage of the pancreatic cysts (p = 0.0016) was significantly higher in patients with DM or high HbA1c levels (n = 9) than in patients without DM or high HbA1c levels (n = 27); however, the difference in the area of the whole pancreas was not significant (p = 0.068). CONCLUSION: Our findings suggest that patients with VHL who have a large area covered by pancreatic cysts are more likely to have DM than those without.

Short-Term Outcomes of 3 Monthly intravitreal Faricimab On Different Subtypes of Neovascular Age-Related Macular Degeneration.

Purpose: To evaluate the efficacy and safety of faricimab injections for treatment-naïve neovascular age-related macular degeneration (nvAMD) patients, including subtypes and pachychoroid phenotypes, and identify predictive factors for visual outcomes. Methods: nvAMD patients were prospectively recruited, receiving three monthly faricimab (6 mg) injections. Best-corrected visual acuity (BCVA) two months after the last injection (month 4) was compared between subtypes, and between pachychoroid neovasculopathy (PNV) and non-PNV eyes. Regression analysis determined factors influencing month 4 BCVA. Results: The study involved 23 patients (12 typical AMD [tAMD], 10 polypoidal choroidal vasculopathy [PCV], 1 retinal angiomatous proliferation [RAP]). Eleven exhibited PNV phenotype. Significant BCVA (P = 4.9 × 10-4) and central retinal thickness (CRT) (P = 1.3 × 10-5) improvements were observed post-faricimab treatment. The therapy demonstrated favourable results for both tAMD and PCV eyes, and non-PNV and PNV eyes. Faricimab achieved dry macula in 77.3% of eyes, with subretinal fluid resolution in most cases, although intraretinal fluid (IRF) often persisted. Multivariable analysis identified external limiting membrane (ELM) presence and IRF as BCVA contributors at month 4. Conclusion: Faricimab demonstrated significant effectiveness and safety in treatment-naïve nvAMD patients, particularly for PCV and PNV eyes. ELM presence and IRF is predictive of visual outcomes.

Pigment Epithelial Detachment and Leak Point Locations in Central Serous Chorioretinopathy.

PURPOSE: To examine the associations between the vortex vein characteristics and locations of the pigment epithelial detachment (PED) and leak point in patients with central serous chorioretinopathy (CSC). DESIGN: Observational case series. METHODS: We evaluated 116 eyes of 104 patients with CSC. The PED and leak point locations were superimposed over the choroidal en face images using widefield swept-source optical coherence tomography and fluorescein angiography. We defined the draining areas of the superior and inferior vortex veins and analyzed their associations with the PED and leak point locations. RESULTS: One of the 116 eyes with a unique irrigation pattern dominated by the nasal vortex vein was excluded from the analysis. Sixty-nine (60%) of the remaining 115 eyes exhibited asymmetry between the superior and inferior vortex veins. PEDs and leak points were in the vortex vein draining area with greater dilation in 66 (96%) of 69 eyes with asymmetry, and none (0%) were in the opposite areas. Both the PEDs and leak points showed significant differences in their distributions (P < .001, respectively). Additionally, 74% of PEDs and 84% of leak points were located upstream of the vortex vein draining areas, whose frequency was significantly higher compared to other areas (P < .001, respectively). CONCLUSION: PED and leak point spatial distributions corresponded with the most terminal part of the dilated vortex veins, suggesting that blood flow disturbances, such as stasis within the affected vortex veins, may be essential in the pathogenesis of CSC.

MACULAR CHORIORETINAL ATROPHY AND VISUAL OUTCOMES IN RANIBIZUMAB- OR AFLIBERCEPT-TREATED MYOPIC CHOROIDAL NEOVASCULARIZATION.

PURPOSE: To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes. METHODS: This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept. RESULTS: Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months ( P < 0.001) in the non-PA group, but not in the PA group. In the PA group, macular chorioretinal atrophy progressed faster ( P < 0.0001), and CNV-MA was more frequent during the 2 years of treatments ( P = 0.04). Even non-PA group eyes sometimes developed CNV-MA (42% at Month 24) if they had a larger CNV and thinner subfoveal choroidal thickness at baseline, resulting in poorer visual prognosis ( P < 0.01). CONCLUSION: Macular PA at baseline was a risk factor for CNV-MA development and was associated with poor visual outcomes.

Exploring the genetic diversity of the Japanese population: Insights from a large-scale whole genome sequencing analysis.

The Japanese archipelago is a terminal location for human migration, and the contemporary Japanese people represent a unique population whose genomic diversity has been shaped by multiple migrations from Eurasia. We analyzed the genomic characteristics that define the genetic makeup of the modern Japanese population from a population genetics perspective from the genomic data of 9,287 samples obtained by high-coverage whole-genome sequencing (WGS) by the National Center Biobank Network. The dataset comprised populations from the Ryukyu Islands and other parts of the Japanese archipelago (Hondo). The Hondo population underwent two episodes of population decline during the Jomon period, corresponding to the Late Neolithic, and the Edo period, corresponding to the Early Modern era, while the Ryukyu population experienced a population decline during the shell midden period of the Late Neolithic in this region. Haplotype analysis suggested increased allele frequencies for genes related to alcohol and fatty acid metabolism, which were reported as loci that had experienced positive natural selection. Two genes related to alcohol metabolism were found to be 12,500 years out of phase with the time when they began to increase in the allele frequency; this finding indicates that the genomic diversity of Japanese people has been shaped by events closely related to agriculture and food production.

Therapeutic effects of faricimab on aflibercept-refractory age-related macular degeneration.

Though vascular endothelial growth factors (VEGF) and other proangiogenic factors, such as angiopoietins (Ang), may be involved in the development of neovascular age-related macular degeneration (nvAMD), only drugs that inhibit the VEGF family are available for the treatment. The newly approved anti-VEGF drug faricimab, which also inhibits Ang-2, is expected to be effective in patients with AMD refractory to conventional anti-VEGF drugs. Therefore, we prospectively investigated the efficacy of faricimab in the treatment of aflibercept-refractory nvAMD. Patients with nvAMD who had been treated with aflibercept in the last year and required bimonthly injections were recruited. 25 eyes showed persistent exudative changes immediately before the faricimab injection (baseline). In these 25 eyes, switching to faricimab did not change visual acuity or central retinal thickness 2 months after the injection; however, 56% of eyes showed reduction or complete absorption of fluid. Notably, 25% of the eyes that showed dry macula at month 2 had no fluid recurrence for up to 4 months. These results indicate that faricimab could benefit some patients with aflibercept-refractory nvAMD.

Widefield choroidal vasculature associated with future condition of subretinal fluid in central serous chorioretinopathy.

Purpose: To examine choroidal angiographic features in the posterior pole associated with resolution or persistency of subretinal fluid (SRF) in eyes with central serous chorioretinopathy (CSC). Design: Observational case series. Methods: Twenty-nine patients with treatment-naïve CSC were divided into two groups based on the presence or absence of SRF 3 months after the initial visit (month 3) without any treatment. Using enhanced depth imaging of widefield swept-source optical coherence tomography, the choroidal thickness (CT), vessel density (VD), and vessel diameter index (VDI) in the superotemporal and inferotemporal subfields on the temporal side of the 18-mm circle from the disc were measured at the initial visit. We calculated the vertical difference in CT and other choroidal angiographic parameters and evaluated their association with the SRF condition at 3 months. Results: The SRF-resolved and SRF-persistent groups included 10 and 19 patients, respectively. At the initial visit, sex, age, axial length, symptom duration, the logarithm of the minimum angle of resolution visual acuity, and foveal thickness were not significantly different between the two groups. The SRF status at month 3 was not associated with the vertical difference in CT and choroidal VD (P = .614, .065, respectively). However, the vertical difference in choroidal VDI was positively associated with the future presence of SRF (P = .017). Conclusions: Vertically asymmetric dilation of choroidal vessels in the posterior pole may be a vasculature feature associated with SRF from CSC and may be a good predictor of future SRF status.

Extensive reduction in choroidal thickness after photodynamic therapy in eyes with central serous chorioretinopathy.

We examined the effect of reduced fluence (rf)-photodynamic therapy (PDT) of the macular area on the wide-field choroidal thickness in 20 eyes with central serous chorioretinopathy (CSC) and 20 age- and sex-matched control eyes. The choroidal thickness at the posterior pole was measured before and after rf-PDT, using a grid with inner and outer rings, each divided into superotemporal, inferotemporal, superonasal, and inferonasal quadrants, respectively, making up a total of nine subfields including the central 3 mm ring. Before treatment, all eyes showed wide-field choroidal thickening from the dilated vortex vein ampulla to the fovea, along the course of the vein. After rf-PDT of the macular area, the choroidal thickness significantly decreased, not only in the irradiated macular area but also outside the arcade vessels in all quadrants (p < 0.001 for all inner subfields; p = 0.035 and p = 0.024 for the outer superonasal and inferonasal subfields, respectively; p < 0.001 and p = 0.004 for the outer superotemporal and inferotemporal subfields, respectively). For control eyes, the choroidal thickness did not differ between the initial visit and follow-up 1.2 ± 0.7 months after the initial visit (p > 0.05 for all subfields). These findings provide new insights into the pathogenesis of CSC and explain the reasons for the effectiveness of rf-PDT for this condition.

Analysis of widefield choroidal thickness maps of healthy eyes using swept source optical coherence tomography.

We aimed to obtain widefield (WF) swept source optical coherence tomography (SS-OCT) data and examine the features of choroidal thickness maps in healthy eyes. The posterior pole choroidal thickness was examined in 127 eyes using enhanced depth imaging of SS-OCT with a viewing angle of 20 (vertical) × 23 (horizontal) mm, and choroidal thickness maps were generated. For SS-OCT image analysis, we developed a grid with inner and outer rings, each divided into superotemporal, inferotemporal, superonasal, and inferonasal quadrants, comprising a total of nine subfields, including the central 3-mm ring. The posterior pole choroidal thicknesses were significantly lower at the periphery than in the central area, in the inferior field than in the superior field, and in the nasal field than in the temporal field (p < 0.001 for all). We also evaluated the effects of age and axial length (AL) on the WF choroidal thickness. The choroidal thickness in all subfields was negatively associated with advanced age (p < 0.05). The choroidal thicknesses in the central and inferonasal inner and outer subfields were negatively associated with AL (p = 0.042, 0.034, and 0.022, respectively). These findings provide insights into the two-dimensional characteristics of choroidal thickness and its association with age and AL.

PREDICTORS OF 3-MONTH AND 1-YEAR VISUAL OUTCOMES AFTER VITRECTOMY WITH SUBRETINAL TISSUE PLASMINOGEN ACTIVATOR INJECTION FOR SUBMACULAR HEMORRHAGE.

PURPOSE: To investigate factors associated with 3-month or 1-year best-corrected visual acuity (BCVA) after vitrectomy with subretinal tissue plasminogen activator injection for submacular hemorrhage (SMH) and to identify the predictors of early displacement. METHODS: This prospective cohort study included consecutive eyes with SMH complicating neovascular age-related macular degeneration or retinal macroaneurysm that underwent vitrectomy with subretinal tissue plasminogen activator injection and were followed up for at least 3 months. Parameters that correlated with 3-month BCVA, 1-year BCVA, and 2-week displacement grade (0-3) were identified. RESULTS: Twenty-nine eyes of 29 patients (73.1 ± 8.4 years; neovascular age-related macular degeneration, 25 eyes) were included. Logarithm of the minimum angle of resolution BCVA improved 3 months after the surgery (baseline, 0.76 [20/115] ± 0.35; 3-month, 0.51 [20/65] ± 0.32; P = 0.006). In multivariable analyses, 1-year logarithm of the minimum angle of resolution BCVA correlated with age ( P = 0.007, ß = 0.39) and SMH recurrence within 1 year after surgery ( P < 0.001, ß = 0.65). Two-week displacement grade correlated with the contrast-to-noise ratio of SMH ( P = 0.001, ß = -0.54). Macular hole occurred in three eyes (10%) with small SMH size and was closed in all eyes via additional vitrectomy with an inverted internal limiting membrane flap technique. CONCLUSION: The recurrence of SMH negatively affected the 1-year visual outcome after vitrectomy with subretinal tissue plasminogen activator injection for SMH. The contrast-to-noise ratio was a useful predictor of early SMH displacement, but not of 1-year BCVA. Further research is necessary to determine the optimal treatment to prevent SMH recurrence.

Striatal dopamine transporter binding differs between dementia with Lewy bodies and Parkinson's disease with dementia.

123I-ioflupane single-photon emission computed tomography (SPECT) is a highly sensitive and established neuroimaging technique for parkinsonian syndromes (PS). However, differentiating PS by visual inspection or analysis of regions of interest is challenging. To date, image analysis has not been able to differentiate dementia with Lewy bodies (DLB) from Parkinson's disease with dementia (PDD). This study aimed to differentiate PS based on the characteristics of striatal dopamine transporter (DAT) binding using voxel-based analysis. We acquired 123I-ioflupane SPECT data from patients with DLB (n = 30), Parkinson's disease (PD; n = 122), PDD (n = 19), multiple system atrophy with predominant parkinsonism (MSA-P; n = 18), and progressive supranuclear palsy (PSP; n = 45). DAT binding was reduced in the posterior striatum of patients with PD and PDD, whereas it was similar in MSA-P, PSP, and DLB. Hippocampal atrophy, visually evaluated by cerebral magnetic resonance imaging, did not affect striatal DAT binding in DLB. DAT binding in the anterior striatum was inversely correlated with the severity of parkinsonism in PD and PDD but not in DLB. Thus, the appearance of striatal DAT binding might indicate different pathological processes in DLB and PDD.

Clinical Characteristics and Progression of Geographic Atrophy in a Japanese Population.

PURPOSE: To elucidate the clinical characteristics and progression rate of geographic atrophy (GA) associated with age-related macular degeneration (AMD) in a Japanese population. DESIGN: Retrospective, multicenter, observational study. PARTICIPANTS: A total of 173 eyes from 173 patients from 6 university hospitals in Japan were included. Of 173 study eyes, 101 eyes from 101 patients were included in the follow-up group. All patients were Japanese, aged ≥ 50 years and had definite GA associated with AMD in at least 1 eye. METHODS: The GA area was measured semiautomatically using fundus autofluorescence (FAF) images. In the follow-up group followed for > 6 months with FAF images, the GA progression rate was calculated by 2 methods: mm2 per year and mm per year using the square-root transformation (SQRT) strategy. Simple and multiple linear regression analyses were used to identify the baseline factors associated with the GA progression rate. MAIN OUTCOME MEASURES: Clinical characteristics of GA and the GA progression rate. RESULTS: The mean age was 76.8 ± 8.8 years, and 109 (63.0%) were males. Sixty-two (35.8%) patients had bilateral GA. The mean GA area was 3.06 ± 4.00 mm2 (1.44 ± 1.00 mm [SQRT]). Thirty-eight eyes (22.0%) were classified as having pachychoroid GA. Drusen and reticular pseudodrusen were detected in 115 (66.5%) and 73 (42.2%) eyes, respectively. The mean subfoveal choroidal thickness was 194.7 ± 105.5 µm. In the follow-up group (follow-up period: 46.2 ± 28.9 months), the mean GA progression rate was 1.01 ± 1.09 mm2 per year (0.23 ± 0.18 mm/year [SQRT]). In the multivariable analysis, the baseline GA area (SQRT; P = 0.002) and the presence of reticular pseudodrusen (P < 0.001) were significantly associated with a greater GA progression rate (SQRT). CONCLUSIONS: Certain clinical characteristics of GA in Asian populations may differ from those in White populations. Asian patients with GA showed male dominance and relatively thicker choroid than White patients. There was a group with GA without drusen but with features of pachychoroid. The GA progression rate in this Asian population was relatively lower than that in White populations. Large GA and reticular pseudodrusen were associated with a greater GA progression rate.

TEN-YEAR VISUAL OUTCOME AND CHANGE IN CHORIORETINAL ATROPHY AFTER INTRAVITREAL RANIBIZUMAB FOR MACULAR NEOVASCULARIZATION IN PATHOLOGIC MYOPIA.

PURPOSE: To investigate the 10-year visual outcome and chorioretinal atrophy after a single intravitreal ranibizumab injection followed by a pro re nata regimen for myopic macular neovascularization in pathologic myopia, and to identify the factors associated with 10-year best-corrected visual acuity (BCVA). METHODS: This retrospective observational study evaluated 26 consecutive treatment-naïve eyes (26 patients) with myopic macular neovascularization in pathologic myopia who underwent a single intravitreal ranibizumab followed by a pro re nata regimen of intravitreal ranibizumab and/or intravitreal aflibercept injection and observed over 10 years. We assessed changes in BCVA and morphological parameters, including the META-PM Study category as a chorioretinal atrophy index. RESULTS: The logarithm of the minimum angle of resolution BCVA changed from 0.36 (Snellen, 20/45) ± 0.39 to 0.39 (20/49) ± 0.36 over 10 years of observation. Compared to baseline, 1-year BCVA improved ( P = 0.002), whereas 2 to 10-year BCVA was not significantly different. Total injection frequency was 3.8 ± 2.6. In none of the eyes, 10-year BCVA was 20/200 or less. Ten-year BCVA correlated with baseline BCVA ( P = 0.01, r = 0.47). The META-PM Study category progressed in 60% of eyes. There were no drug-induced complications. CONCLUSION: Best-corrected visual acuity in eyes with myopic macular neovascularization in pathologic myopia was maintained for 10 years after a single intravitreal ranibizumab followed by a pro re nata regimen without drug-induced complications. The META-PM Study category progressed in 60% of eyes, especially those with older baseline age. Early diagnosis and treatment of myopic macular neovascularization are essential to maintain good long-term BCVA.

Clinical features and risk factors of iodinated contrast media (ICM)-induced anaphylaxis.

PURPOSE: To evaluate the clinical features and risk factors of iodinated contrast media (ICM)-induced anaphylaxis. METHODS: This retrospective study included all patients undergoing contrast-enhanced computed tomography (CT) with intravenous ICM administration (iopamidol, iohexol, iomeprol, iopromide, ioversol) at our hospital between April 2016 and September 2021. Medical records of patients who experienced anaphylaxis were reviewed, and the multivariable regression model using generalized estimating equations was employed to eliminate the effect of intrapatient correlation. RESULTS: Of the 76,194 ICM administrations (44,099 men [58 %] and 32,095 women; age, median, 68 years) to 27, 696 patients, anaphylaxis occurred in 45 cases in 45 different patients (0.06 % of administration and 0.16 % of patients), all with onset within 30 min after administration. Thirty-one (69 %) had no risk factors for ADRs, including 14 (31 %) who had previously used the same ICM that caused anaphylaxis. Thirty-one patients (69 %) had a history of ICM use without any ADRs. Four patients (8.9 %) received oral steroid premedication. The only factor associated with anaphylaxis was the type of ICM, with an odds ratio (OR) of 6.8 (p < 0.001) for iomeprol with iopamidol as a reference. No significant differences in OR of anaphylaxis were found for patients' age, sex, or premedication. CONCLUSION: The overall incidence of anaphylaxis due to ICM was very low. More than half of the cases had no risk factors for ADRs and had no ADRs on past ICM administration, although the ICM type was associated with a higher OR.

A Rare Case of Blindness Caused by Syphilis with Malignant Hypertensive Nephropathy.

The number of patients with syphilis has been rapidly increasing. Without treatment, syphilis can damage various organs and become life-threatening. We herein report a 29-year-old woman diagnosed with neurosyphilis, acute hydrocephalus, syphilitic uveitis combined with hypertensive retinopathy, and malignant hypertensive nephropathy. To our knowledge, this is the first report of syphilis complicated with malignant hypertensive nephropathy proven by a renal biopsy. Neurosyphilis was successfully treated with intravenous penicillin G, and severe hypertension subsequently resolved. However, delayed medical examinations and complications of syphilitic uveitis and hypertensive retinopathy resulted in irreversible visual loss. To prevent irreversible organ damage, early treatment is essential.

Novel Manifestation of Retinal Hemangioblastomas Detected by OCT Angiography in von Hippel-Lindau Disease.

PURPOSE: To elucidate the clinical characteristics of atypical retinal vascular proliferation in patients with von Hippel-Lindau (VHL) disease using OCT angiography (OCTA). DESIGN: Prospective, observational study. PARTICIPANTS: Fifty-seven consecutive patients with a diagnosis of VHL disease who visited Kyoto University Hospital between January 2019 and March 2022. METHODS: Retinal hemangioblastomas (RHs) were assessed using multimodal imaging including OCTA. Retinal hemangioblastomas were classified into 2 phenotypes: nodular and flat. Nodular RHs were defined as typical RHs that were globular, well-circumscribed tumors, often accompanied with dilated feeder arterioles and draining venules. Flat RHs lacked a protruded red or colored mass, had variable and indistinct borders, and were not accompanied with feeder and draining vessels. MAIN OUTCOME MEASURES: The prevalence, distribution, and description of atypical flat RHs. RESULTS: Among 57 consecutive patients with VHL disease, 37 patients (64.9%) showed RHs in at least 1 eye. Bilateral RHs were seen in 23 patients (62.2%). Among 58 eyes of 37 patients with RHs, typical nodular RHs were detected in 54 eyes. Nodular RHs were seen mainly in the peripheral retina and occasionally in the peripapillary region, and they showed exudative changes in some cases. Flat RHs were detected in 7 eyes (12.1%). Four eyes showed only flat RHs, and 3 eyes showed both types in the same eye. Most flat RHs appeared as retinal hemorrhages or faint flat abnormal retinal vessels in the inner retina on the fundus examination, often within the macula area or peripapillary. In all eyes with flat RHs, OCTA showed abundant blood flow in the lesions. OCT revealed that flat RHs were seen mainly between the retinal nerve fiber layer and the ganglion cell layer, and occasionally within the inner nuclear layer. During a mean follow-up period of 20.4 ± 15.0 months, no flat RHs accompanied exudative change, tractional retinal detachment, or progression in size. CONCLUSIONS: Patients with VHL disease can demonstrate 2 distinct types of RHs: the classic nodular type and an atypical flat type. OCT angiography can be useful in improving the detection of atypical flat RHs, which can be difficult to detect clinically.

Seven-year outcome after 1-year fixed regimen of intravitreal aflibercept injections followed by pro re nata treatment for neovascular age-related macular degeneration.

PURPOSE: The study aims to investigate the 7-year best-corrected visual acuity (BCVA) course after 1-year fixed regimen of intravitreal aflibercept injection (IVA) for neovascular age-related macular degeneration (nAMD) and to identify factors affecting this BCVA. METHODS: This longitudinal, observational study included 63 treatment-naïve eyes (61 patients) with nAMD, treated with 1-year fixed regimen of IVA-3 monthly injections and 4 subsequent bimonthly injections-essentially followed by PRN regimen of IVA but sometimes followed by agent switching, photodynamic therapy (PDT), or vitrectomy, as needed. We assessed BCVA changes over a 7-year period. Morphologically, we assessed central retinal thickness (CRT), central choroidal thickness (CCT), subfoveal pigment epithelial detachment (PED) height, vitreomacular traction/adhesion (VMT/VMA), epiretinal membrane (ERM), and macular atrophy involving the fovea. RESULTS: Logarithm of the minimum angle of resolution (logMAR) BCVA changed from 0.20 ± 0.24 to 0.29 ± 0.45 over 7 years. BCVA improved significantly after years 1 and 2 (P = 0.002 and 0.001, respectively) and then slowly decreased. BCVA after years 3-7 did not significantly differ from baseline. CRT and CCT decreased significantly during follow-up, while PED height did not. VMT/VMA decreased significantly, whereas ERM and macular atrophy increased significantly. Seven-year and baseline BCVA positively correlated (P = 0.007, ß = 0.35). CONCLUSIONS: BCVA was maintained for 7 years in nAMD eyes after 1-year fixed regimen of IVA, essentially followed by PRN regimen, but sometimes followed by agent switching, PDT, or vitrectomy, without severe drug-induced complications. Thus, early diagnosis and treatment of nAMD are essential for maintaining good long-term BCVA, even in eyes with relatively poor baseline vision.

Macular atrophy at 5 years after photodynamic therapy for polypoidal choroidal vasculopathy.

PURPOSE: To investigate predictors for macular atrophy (MA) involving the fovea after photodynamic therapy (PDT) followed by pro re nata (PRN) treatment for polypoidal choroidal vasculopathy (PCV). METHODS: This prospective observational study analysed treatment-naïve eyes with symptomatic PCV without MA at baseline which were followed up for 5 years. All eyes were initially treated with PDT, followed by a PRN regimen of anti-vascular endothelial growth factor (VEGF) therapy and/or PDT. We assigned eyes with and eyes without development of MA involving the fovea 5 years after the initial treatment into MA and non-MA groups, respectively. Baseline parameters and the number of treatments were compared between the two groups. RESULTS: Seventy-two eyes of 69 consecutive patients were included, and 29 eyes of 29 patients were analysed. Twelve (41%) and 17 (59%) eyes were assigned into the MA and non-MA groups, respectively. There were significant differences in subfoveal choroidal thickness (226.2 ± 47.8 µm vs. 278.8 ± 68.1 µm, P = 0.03) and number of anti-VEGF injections (13.7 ± 9.6 vs. 5.4 ± 5.6, P = 0.007) between the MA and non-MA groups, but not in the number of PDT sessions (P = 0.71). Best-corrected visual acuity at 5 years in the MA group was lower than in the non-MA group (P = 0.048). CONCLUSION: Our long-term observation suggests that a thin subfoveal choroid at baseline and many followed anti-VEGF injections in a PRN regimen increase the risk for development of MA involving the fovea 5 years after PDT.
