RESUMO

PURPOSE: To evaluate the visual field after anti-vascular endothelial growth factor (VEGF) therapy and laser treatment for retinopathy of prematurity. METHOD: Retrospective cohort study. Infants with retinopathy of prematurity treated by anti-VEGF therapy or laser treatment were included in the study. Degrees of visual field in eight directions examined by Goldmann perimeter (intensity, 1000 apostilb; size, V4e = 64 mm2) were compared between the anti-VEGF therapy and laser treatment groups. The visual acuity (VA) and spherical equivalent refraction were also compared between the two groups. RESULTS: Nine eyes with anti-VEGF therapy and 12 eyes with laser treatment were enrolled in the analysis. The total, upper, nasal upper, nasal, nasal lower, temporal lower, and temporal upper visual fields were significantly wider in the eyes with anti-VEGF therapy than in those with laser treatment (496 vs 416, P = .002; 53 vs 45, P = .008; 56 vs 43, P = .003; 58 vs 39, P < .001; 55 vs 44, P = .01; 72 vs 65, P = .01; and 62 vs 56, P = .03, respectively). The logarithm of the minimum angle of resolution VA tended to be better in the eyes with anti-VEGF therapy than in those with laser treatment (0.01 vs 0.15, P = .06). Eyes with anti-VEGF therapy had significantly lower myopia than those with laser treatment (spherical equivalent refraction: -0.72 vs -5.7, P = .001). CONCLUSION: Anti-VEGF therapy may provide a wider visual field, better VA, and less myopia compared with laser treatment.

RESUMO

PURPOSE: To investigate the blood neutrophil-to-lymphocyte ratio (NLR) as a risk factor for retinopathy of prematurity (ROP) development or treatment. METHODS: Retrospective cohort study. Infants who underwent ROP screening at Shiga University of Medical Science Hospital and Omihachiman Community Medical Center between April 2010 and December 2021 were included in this study. Screening criteria were gestational age (GA) < 32 weeks or birth weight (BW) < 1500 g. Multivariate logistic regression analysis was applied to investigate whether the NLR constituted an independent risk factor for ROP development or treatment. The objective variable was ROP development or treatment, and the explanatory variables were GA, BW, NLR, maternal infection or clinical chorioamnionitis and corticosteroid use by the mother. Maternal infection or clinical chorioamnionitis and corticosteroid use by the mother was included in the explanatory variables to adjust for factors affecting the NLR. RESULTS: In total, 220 infants met the inclusion criteria, of whom 125 developed ROP, whereas 95 infants did not display ROP. GA was significantly associated with ROP development (odds ratio (OR): 0.41, p < 0.001); however, the NLR was not significantly associated with ROP development (OR: 1.0, p = 0.74). Thirty-eight infants received treatment for ROP, whereas 182 infants had no such treatment. BW and the NLR were significantly associated with ROP treatment (OR: 1.6 and 0.66, p < 0.001 and 0.003, respectively). CONCLUSION: The NLR was not a risk factor for ROP development but was a risk factor for ROP treatment.

RESUMO

PURPOSE: To evaluate 1-year efficacy, durability, and safety of faricimab among patients from Asian countries in the TENAYA/LUCERNE trials of neovascular age-related macular degeneration (nAMD). METHODS: Treatment-naïve patients with nAMD were randomly assigned (1:1) to faricimab 6.0 mg up to every 16 weeks (Q16W), based on disease activity at weeks 20 and 24, or aflibercept 2.0 mg Q8W. The primary endpoint was change in best-corrected visual acuity (BCVA) from baseline averaged over weeks 40, 44, and 48. RESULTS: In the pooled TENAYA/LUCERNE trials, there were 120 (9.0%) and 1209 (91.0%) patients in the Asian (faricimab n = 61; aflibercept n = 59) and non-Asian country (faricimab n = 604; aflibercept n = 605) subgroups, respectively. In the Asian country subgroup, mean BCVA change from baseline at the primary endpoint visits was 7.1 (95% CI, 4.3-9.8) letters with faricimab and 7.2 (4.4-10.0) letters with aflibercept. In non-Asian country patients, mean vision gains were 6.1 (5.2-7.1) and 5.7 (4.8-6.7) letters with faricimab and aflibercept, respectively. At week 48, 59.6% of Asian country patients in the faricimab group achieved Q16W dosing (vs. 43.9% non-Asian) and 91.2% achieved ≥ Q12W dosing (vs. 77.5% non-Asian). Central subfield thickness reductions were similar between the subgroups, with meaningful and similar reductions from baseline observed at the primary endpoint visits and over time. Faricimab was well tolerated in both subgroups, with an acceptable safety profile. CONCLUSION: Consistent with the global TENAYA/LUCERNE findings, faricimab up to Q16W showed sustained visual and anatomical benefits in patients with nAMD from Asian and non-Asian countries.

RESUMO

BACKGROUND: Primary cilia are sensory organelles crucial for organ development. The pivotal structure of the primary cilia is a microtubule that is generated via tubulin polymerization reaction that occurs in the basal body. It remains to be elucidated how molecules with distinct physicochemical properties contribute to the formation of the primary cilia. RESULTS: Here we show that brain expressed X-linked 1 (Bex1) plays an essential role in tubulin polymerization and primary cilia formation. The Bex1 protein shows the physicochemical property of being an intrinsically disordered protein (IDP). Bex1 shows cell density-dependent accumulation as a condensate either in nucleoli at a low cell density or at the apical cell surface at a high cell density. The apical Bex1 localizes to the basal body. Bex1 knockout mice present ciliopathy phenotypes and exhibit ciliary defects in the retina and striatum. Bex1 recombinant protein shows binding capacity to guanosine triphosphate (GTP) and forms the condensate that facilitates tubulin polymerization in the reconstituted system. CONCLUSIONS: Our data reveals that Bex1 plays an essential role for the primary cilia formation through providing the reaction field for the tubulin polymerization.

RESUMO

Retinopathy of prematurity (ROP) is a leading cause of childhood blindness and intravitreal anti-vascular endothelial growth factor (VEGF) injection is becoming a first-line choice for treatment of ROP. However, there is a major concern that intravitreally injected anti-VEGF agents could escape from the eye into the systemic circulation and impair systemic development. Moreover, escaped anti-VEGF agents could have an effect on the retina of the fellow eye. In this study, we investigated the hematogenous effect of a single intravitreal anti-VEGF injection in a mouse model of ROP. Here, we showed that single intravitreal aflibercept injection to one eye can affect body weight gain, the fellow eye, and renal vessels, although no apparent effect was observed in brain vessels. Furthermore, this hematogenous effect was dose-dependent. Our results provide very important insights into the clinical use of anti-VEGF agents for ROP treatment.

RESUMO

PURPOSE: To create a model for prediction of postoperative visual acuity (VA) after vitrectomy for macular hole (MH) treatment using preoperative optical coherence tomography (OCT) images, using deep learning (DL)-based artificial intelligence. METHODS: This was a retrospective single-center study. We evaluated 259 eyes that underwent vitrectomy for MHs. We divided the eyes into four groups, based on their 6-month postoperative Snellen VA values: (A) ≥ 20/20; (B) 20/25-20/32; (C) 20/32-20/63; and (D) ≤ 20/100. Training data were randomly selected, comprising 20 eyes in each group. Test data were also randomly selected, comprising 52 total eyes in the same proportions as those of each group in the total database. Preoperative OCT images with corresponding postoperative VA values were used to train the original DL network. The final prediction of postoperative VA was subjected to regression analysis based on inferences made with DL network output. We created a model for predicting postoperative VA from preoperative VA, MH size, and age using multivariate linear regression. Precision values were determined, and correlation coefficients between predicted and actual postoperative VA values were calculated in two models. RESULTS: The DL and multivariate models had precision values of 46% and 40%, respectively. The predicted postoperative VA values on the basis of DL and on preoperative VA and MH size were correlated with actual postoperative VA at 6 months postoperatively (P < .0001 and P < .0001, r = .62 and r = .55, respectively). CONCLUSION: Postoperative VA after MH treatment could be predicted via DL using preoperative OCT images with greater accuracy than multivariate linear regression using preoperative VA, MH size, and age.

RESUMO

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.

RESUMO

PURPOSE: To report the 2-year efficacy and safety of abicipar every 8 weeks and quarterly (after initial doses) compared with monthly ranibizumab in patients with treatment-naïve neovascular age-related macular degeneration (nAMD). DESIGN: Two multicenter, randomized, phase 3 clinical trials with identical protocols (CEDAR and SEQUOIA). Analyses used pooled trial data. PARTICIPANTS: The trials enrolled 1888 patients (1 eye/patient) with active choroidal neovascularization secondary to age-related macular degeneration and best-corrected visual acuity (BCVA) of 24 to 73 Early Treatment Diabetic Retinopathy Study letters. METHODS: At enrollment, patients were assigned to study eye treatment with abicipar 2 mg every 8 weeks after initial doses at baseline and weeks 4 and 8 (abicipar Q8, n = 630), abicipar 2 mg every 12 weeks after initial doses at baseline and weeks 4 and 12 (abicipar Q12, n = 628), or ranibizumab 0.5 mg every 4 weeks (ranibizumab Q4, n = 630). MAIN OUTCOME MEASURES: Efficacy measures included stable vision (<15-letter loss in BCVA from baseline) and change from baseline in BCVA and central retinal thickness (CRT). Safety measures included adverse events (AEs). RESULTS: For patients who completed the study, efficacy of abicipar after initial doses was maintained through week 104. At week 104, the proportion of patients with stable vision was 93.0% (396/426), 89.8% (379/422), and 94.4% (470/498); mean change in BCVA from baseline was +7.8 letters, +6.1 letters, and +8.5 letters, and mean change in CRT from baseline was -147 µm, -146 µm, and -142 µm in the abicipar Q8 (14 injections), abicipar Q12 (10 injections), and ranibizumab Q4 (25 injections) groups, respectively. The overall incidence of intraocular inflammation (IOI) AEs was 15.4%, 15.3%, and 0.3% from baseline through week 52 and 16.2%, 17.6%, and 1.3% from baseline through week 104 in the abicipar Q8, abicipar Q12, and ranibizumab Q4 groups, respectively. CONCLUSIONS: Two-year results show efficacy of abicipar Q8 and Q12 in nAMD. First onset of IOI events with abicipar was much reduced in the second year and comparable with ranibizumab (0.8% and 2.3% vs. 1.0%). The extended duration of effect of abicipar allows for quarterly dosing and reduced treatment burden.

RESUMO

PURPOSE: To investigate acquired color vision deficiency (CVD) using the Rabin cone contrast test (RCCT) in patients with retinal vein occlusion (RVO). METHODS: We retrospectively evaluated 39 patients with macular edema due to RVO who were treated with intravitreal injections of anti-VEGF agents and demonstrated improvement of best-corrected visual acuity to 20/20 Snellen VA or better. The acquired CVD was evaluated by the RCCT and standard pseudo-isochromatic plates-part 2 (SPP-2). RESULTS: Mean L, M, and S color contrast test (CCT) scores were significantly lower in RVO eyes than in the fellow eyes (L CCTs, 70.0 ± 13.3 vs. 90.0 ± 8.0, respectively, P < 0.01; M CCTs, 85.0 ± 16.6 vs. 95.0 ± 5.7, respectively, P < 0.01; S CCTs, 80.0 ± 21.5 vs. 95.0 ± 7.1, respectively, P < 0.01). Acquired CVD was diagnosed in 25 eyes of 39 patients by the RCCT and in 15 eyes of 39 patients by SPP-2. The RCCT was performed on two different days in 21 patients. It revealed acquired CVD in 17 eyes on the first day and in 10 eyes on the second day. Acquired CVD was improved in 9 eyes, unchanged in 8 eyes, and worsened in 2 eyes. CONCLUSIONS: The RCCT revealed eyes with RVO had acquired CVD. Acquired CVD caused by RVO can be improved further in some cases even after recovery of vision to 20/20. The RCCT may be able to quantitatively diagnose acquired CVD status.

RESUMO

PURPOSE: To explore the relationship between retinal fluid status and best-corrected visual acuity (BCVA) in patients treated with intravitreal aflibercept (IVT-AFL) treat-and-extend (T&E) in the ALTAIR study. METHODS: Outcomes were investigated according to overall fluid status at week 16 (predefined) and the relationship between any fluid, intraretinal fluid (IRF), subretinal fluid (SRF), or pigment epithelial detachment with BCVA at baseline, and weeks 16, 52, and 96 (post-hoc). The analyses involved treatment-naïve patients (N = 246) with exudative age-related macular degeneration (AMD), aged ≥ 50 years with BCVA of 73-25 Early Treatment Diabetic Retinopathy Study letters, who participated in the ALTAIR study. RESULTS: The mean (standard deviation) change in BCVA from baseline to week 52 was + 10.6 (10.9) and + 6.5 (16.0) letters in patients without and with fluid at week 16, respectively; and to week 96 was + 9.1 (14.3) and + 4.3 (16.1) letters in patients without and with fluid at week 16, respectively. The last injection interval was 16 weeks in 33.6% and 2.0% (week 52), and 62.9% and 17.6% (week 96) of patients without or with fluid at week 16, respectively. At baseline, 35.7% of patients had IRF and 85.2% of patients had SRF, which decreased to 11.8% (IRF) and 31.7% (SRF) of patients, 8.5% (IRF) and 18.7% (SRF), and 6.5% (IRF) and 20.7% (SRF) at weeks 16, 52, and 96, respectively. Presence of IRF at all timepoints was associated with poorer BCVA than if IRF was absent, while the presence of SRF was not associated with poorer BCVA compared with the absence of SRF. CONCLUSION: IVT-AFL T&E dosing was effective at clearing fluid regardless of fluid type in ~ 80% of patients with exudative AMD. Patients without fluid at week 16 had numerically better BCVA than those with fluid at week 16. Over 60% of patients without fluid at week 16 achieved the maximum treatment interval of 16 weeks by study end, compared with < 20% of patients with fluid at week 16. IRF (weeks 16, 52, 96), although evident in a small number of patients, was associated with poorer BCVA, whereas SRF was not. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02305238.

RESUMO

PURPOSE: We investigated 10-year changes in baseline best-corrected visual acuity (BCVA), as well as functional and anatomical changes at 1 and 2 years after initial treatment, in eyes with treatment-naïve neovascular age-related macular degeneration (nAMD). METHODS: This retrospective, multicenter, case series reviewed patients with treatment-naïve nAMD who underwent initial treatment from 2006 to 2015, using photodynamic therapy (PDT), anti-vascular endothelial growth factor (VEGF), or a combination of PDT and anti-VEGF. BCVA and central retinal subfield thickness (CRST), were measured at baseline and at 1 or 2 years of follow-up. RESULTS: In total, 3096 eyes of 3096 patients were included from 14 hospitals. Mean BCVA at baseline became significantly better over the 10-year study period (P < 0.001). BCVA at 1 year significantly improved from baseline in patients who underwent initial treatment from 2009 to 2015 (P = 0.001, 2009; P = 0.004, 2010; P = 0.01, 2011; P < 0.001, 2012-2015). BCVA at 2 years significantly improved from baseline in patients who underwent initial treatment from 2012 to 2015 (P < 0.001, 2012; P < 0.001, 2013-2015). CRST at 1 year decreased significantly from CRST at baseline, each year from 2006 to 2015 (P < 0.001, 2006-2015). CRST at 2 years decreased significantly from CRST at baseline, each year from 2006 to 2015 (P = 0.03, 2006; P < 0.001, 2007-2015). CONCLUSION: Baseline BCVA with treatment-naïve nAMD tended to become better during the study period. BCVA at 1 year improved in the era of anti-VEGF; BCVA at 2 years improved in patients who underwent initial treatment in 2012 or later; and CRST decreased in each year during the study period.

RESUMO

PURPOSE: The aim of the current study was to investigate the correlation between the pretreatment aqueous level of vascular endothelial growth factor (VEGF) and clinical activity in neovascular age-related macular degeneration. METHODS: Patients with neovascular age-related macular degeneration treated by intravitreal ranibizumab injections and followed for 12 months were included in the current study. The treatment regimen consisted of three consecutive monthly intravitreal ranibizumab injections (loading treatment) followed by a pro re nata (PRN) treatment regimen. The aqueous VEGF levels were measured by enzyme-linked immunosorbent assay using aqueous humor samples obtained just before the first intravitreal ranibizumab injections. RESULTS: Sixty-four eyes of 64 patients were included in the current study. The mean number of intravitreal ranibizumab injections during 12 months was 4.6 ± 1.4, and 17 eyes had no recurrence after loading treatment. The mean aqueous VEGF level was significantly higher in eyes with recurrence after loading treatment than in eyes without recurrence (107.6 vs. 83.8 pg/mL, respectively; P = 0.04) and significantly higher in eyes with recurrence within 3 months after loading treatment than in other eyes (114.9 vs. 86.7 pg/mL, respectively; P < 0.01). CONCLUSION: Pretreatment aqueous VEGF level was significantly correlated with the likelihood of recurrence in neovascular age-related macular degeneration. The measurement of pretreatment aqueous VEGF level may be useful to determine the best treatment options for patients with neovascular age-related macular degeneration.

RESUMO

PURPOSE: To determine the characteristics of fundus autofluorescence (FAF) images and visual functions in eyes with Stickler syndrome using ultra-widefield FAF images. METHODS: Forty-six eyes of 26 patients with mutations in the COL2A1 gene underwent ultra-widefield FAF imaging. The eyes were categorized into three types; no signs of abnormal AF, predominantly hyperfluorescent AF (hyper-AF), and predominantly hypofluorescent AF (hypo-AF). Goldmann perimetry was performed on 34 eyes, and line-scan images of the abnormal AF lesions were obtained by swept-source optical coherence tomography in 4 eyes. RESULTS: Abnormal AF lesions were found in 37 eyes of 21 (80.7%) of the 26 patients. Hyper-AF was found in 15 eyes and hypo-AF was found in 22 eyes. The FAF changes corresponded with the funduscopically observed radial paravascular retinal degeneration. The average age at the examination was significantly younger in patients who had eyes with hyper-AF or no abnormal AF than in those with hypo-AF (12.8 vs. 28.4 years; P = 0.009). Abnormal AF-associated visual field defects were found in 5/10 (50%) eyes with hyper-AF and 17/18 (94%) eyes with hypo-AF. Hyper-AF changes tended to appear before retinal changes were detectable by fluorescein angiography. An absence of the ellipsoid zone and the outer nuclear layer and a thinning of the overall retinal thickness were found corresponding to the hypo-AF lesions in the swept source optical coherence tomography images. CONCLUSION: Abnormal FAF is characteristic of eyes with Stickler syndrome. Age-related alterations of the FAF was associated with visual field defects and disruption of the photoreceptors and retinal pigment epithelial cells.

RESUMO

PURPOSE: To compare the efficacy and safety of abicipar every 8 weeks and quarterly (after initial doses) versus ranibizumab every 4 weeks in treatment-naïve patients with neovascular age-related macular degeneration (AMD). DESIGN: Two randomized, multicenter, double-masked, parallel-group, active-controlled, phase 3 clinical trials (CEDAR, SEQUOIA) with identical protocols were conducted. Data from both trials were pooled for analysis. PARTICIPANTS: Patients with active choroidal neovascularization secondary to AMD and best-corrected visual acuity (BCVA) of 24-73 Early Treatment Diabetic Retinopathy Study letters in the study eye were enrolled. METHODS: Patients (n = 1888) were randomized in a 1:1:1 ratio to study eye treatment with abicipar 2 mg every 8 weeks after 3 initial doses at baseline and weeks 4 and 8 (Q8), abicipar 2 mg every 12 weeks after 3 initial doses at baseline and weeks 4 and 12 (Q12), or ranibizumab 0.5 mg every 4 weeks (Q4). MAIN OUTCOME MEASURES: The primary efficacy end point was proportion of patients with stable vision (defined as <15-letter loss in BCVA from baseline) in the study eye at week 52. Secondary end points included change from baseline in BCVA and central retinal thickness (CRT) at week 52. Safety measures included adverse events (AEs). RESULTS: The proportion of patients with stable vision at week 52 was 93.2%, 91.3%, and 95.8% in the abicipar Q8, abicipar Q12, and ranibizumab Q4 groups, respectively, with both abicipar Q8 and Q12 noninferior to ranibizumab Q4. Week 52 mean change from baseline in BCVA was 7.5, 6.4, and 8.4 letters and in CRT was -144, -145, and -144 µm in the abicipar Q8, abicipar Q12, and ranibizumab Q4 groups, respectively. Incidence of intraocular inflammation (IOI) AEs was 15.4%, 15.3%, and 0.3%, respectively. The IOI AEs were typically mild or moderate in severity and treated with topical corticosteroids; 62 of 192 patients (32.3%) received oral and/or injectable corticosteroids. CONCLUSIONS: Abicipar Q8 and Q12 were both noninferior to ranibizumab Q4 in the primary end point of stable vision at week 52. Intraocular inflammation was more frequent with abicipar. Quarterly and Q8 abicipar reduce nAMD disease and treatment burden compared with monthly treatment.

RESUMO

PURPOSE: To evaluate the effectiveness, safety, and treatment patterns of ranibizumab 0.5 mg in treatment-naive patients with neovascular age-related macular degeneration enrolled in LUMINOUS study. METHODS: This 5-year, prospective, multicenter, observational study recruited 30,138 adult patients (treatment-naive or previously treated with ranibizumab or other ocular treatments) who were treated according to the local ranibizumab label. RESULTS: Six thousand two hundred and forty-one treatment-naive neovascular age-related macular degeneration patients were recruited. Baseline (BL) demographics were, mean (SD) age 75.0 (10.2) years, 54.9% females, and 66.5% Caucasian. The mean (SD) visual acuity (VA; letters) gain at 1 year was 3.1 (16.51) (n = 3,379; BLVA, 51.9 letters [Snellen: 20/92]) with a mean (SD) of 5.0 (2.7) injections and 8.8 (3.3) monitoring visits. Presented by injection frequencies <3 (n = 537), 3 to 6 (n = 1,924), and >6 (n = 918), visual acuity gains were 1.6 (14.93), 3.3 (16.57), and 3.7 (17.21) letters, respectively. Stratified by BLVA <23 (n = 382), 23 to <39 (n = 559), 39 to <60 (n = 929), 60 to <74 (n = 994), and ≥74 (n = 515), visual acuity change was 12.6 (20.63), 6.7 (17.88), 3.6 (16.41), 0.3 (13.83), and -3.0 (11.82) letters, respectively. The incidence of ocular/nonocular adverse events was 8.2%/12.8% and serious adverse events were 0.9%/7.4%, respectively. CONCLUSION: These results demonstrate the effectiveness and safety of ranibizumab in treatment-naive neovascular age-related macular degeneration patients.

RESUMO

PURPOSE: To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) in Japanese patients with diabetic macular edema (DME). METHODS: VIVID-DME was a Phase 3 study comprising patients with DME randomized 1:1:1 to IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 4 weeks until Week 16 then 8-week dosing (2q8), and laser. A total of 403 patients (76 Japanese) were included in this study. VIVID-Japan (72; all Japanese patients) was a nonrandomized, open-label study comprising Japanese patients with DME receiving IAI 2q4 until Week 16, then 2q8. Primary efficacy endpoint (Week 52) of VIVID-DME was mean change from baseline in best-corrected visual acuity; VIVID-Japan evaluated safety and tolerability. RESULTS: Mean change in best-corrected visual acuity (letters) for 2q4, 2q8, and laser groups was +10.6, +10.9, and +1.2 and +9.8, +9.5, and +1.1 in the non-Japanese and Japanese populations of VIVID-DME, respectively. In VIVID-Japan, it was +9.3 for IAI 2q8. Intravitreal aflibercept injection also provided consistently greater benefits for anatomical outcomes versus laser. Adverse events were consistent with the known safety profile of IAI. CONCLUSION: In Japanese patients with DME, IAI treatment was superior to laser for visual and anatomical outcomes and resulted in efficacy and safety outcomes similar to those in a non-Japanese patient population.

RESUMO

PURPOSE: To compare the ability of wide-angle optical coherence tomography angiography (OCTA) with that of ultra-wide field fluorescein angiography (UWFFA) to detect non-perfusion areas (NPAs) or retinal neovascularization (NV) in eyes with diabetic retinopathy (DR). METHODS: Patients with DR underwent UWFFA using the Optos® panoramic 200Tx imaging system and wide-angle OCTA with 12 × 12 mm fields of five visual fixations using the PLEX Elite 9000®. We compared the abilities of UWFFA and OCTA to detect NPAs and NV. RESULTS: Fifty-eight eyes of 33 patients (mean age, 60.0 years old; female/male, 16/17) with DR were evaluated. NPAs were detected in 47 out of 58 eyes using UWFFA and in 48 eyes using OCTA. NVs were detected in 25 out of the 58 eyes using UWFFA and in 26 eyes using OCTA. The sensitivity for detection of NPA using OCTA was 0.98, and the specificity was 0.82. The sensitivity for detection of NV was 1.0, and the specificity was 0.97. CONCLUSION: The wide-angle OCTA seems to be clinically useful for the detection of NPAs or NV.

RESUMO

IMPORTANCE: Clinical evidence supports the efficacy of bimonthly aflibercept injection for age-related macular degeneration. BACKGROUND: The study aimed to evaluate aqueous vascular endothelial growth factor and aflibercept concentrations and the efficacy of bimonthly aflibercept in patients with age-related macular degeneration. DESIGN: This study is a prospective, interventional case series. PARTICIPANTS: Enrolled were 35 eyes with exudative age-related macular degeneration from 35 patients. METHODS: Patients received three bimonthly intravitreal aflibercept without loading doses. We collected the aqueous humor just before each injection, measured vascular endothelial growth factor and aflibercept concentrations by enzyme-linked immunosorbent assay and measured best-corrected visual acuity and central retinal subfield thickness before and after the injections. MAIN OUTCOME MEASURES: Aqueous vascular endothelial growth factor and aflibercept concentrations were measured. RESULTS: The vascular endothelial growth factor concentration was 135.4 ± 60.5 pg/mL (mean ± standard deviation, range 60.6-323.4) at baseline and below the lowest detectable limit in all eyes at month 2 and in 32 eyes at month 4 (P < 0.001 [month 2] and P < 0.001 [month 4]). The mean aflibercept concentration was 20.3 ng/mL at month 2 and 28.0 ng/mL at month 4. The mean logarithm of the minimum angle of resolution visual acuity improved from 0.50 ± 0.36 at baseline to 0.36 ± 0.40 at month 6 (P < 0.001). The mean central retinal subfield thickness decreased from 353 ± 100 µm at baseline to 236 ± 45 µm at month 6 (P < 0.001). CONCLUSIONS AND RELEVANCE: Bimonthly aflibercept injections without loading doses may be considered a treatment option for age-related macular degeneration.

RESUMO

PURPOSE: To determine the microstructure of the fovea in patients with Stickler syndrome using imaging by spectral-domain optical coherence tomography (SD OCT) and swept-source OCT. DESIGN: Retrospective case series study. PARTICIPANTS: A total of 39 eyes of 25 patients with genetically confirmed Stickler syndrome were studied. METHODS: All of the patients had mutations in the COL2A1 gene and were diagnosed with Stickler syndrome. Cross-sectional OCT images, OCT angiography (OCTA), and en face OCT images were assessed. The ratio of the foveal inner retinal layer (fIRL) thickness to the parafoveal inner retinal layer (pIRL) thickness, the ratio of the foveal outer retinal layer (fORL) thickness to the parafoveal outer retinal layer (pORL) thickness, and the size of the foveal avascular zone (FAZ) were determined. MAIN OUTCOME MEASURES: The degree of foveal hypoplasia and the best-corrected visual acuity in patients with Stickler syndrome. RESULTS: A persistence of the inner retinal layers in the fovea with an fIRL/pIRL ratio >0.2 was present in 32 of the 39 eyes (82%). Optical coherence tomography angiography showed that the FAZ was smaller, 0 to 0.19 mm2, than that of normal eyes, in 25 eyes of 17 patients who underwent OCTA. There was no significant correlation between the visual acuities and the fIRL/pIRL ratios. CONCLUSIONS: A mild foveal hypoplasia with a persistence of the IRL is characteristic of eyes with Stickler syndrome. The visual acuities were not correlated with the fIRL/pIRL ratios.
