RESUMO
In an aging population, the prevalence and burden of diabetes mellitus, diabetic retinopathy, and vision-threatening diabetic macular edema (DME) are only expected to rise around the world. Similarly to other complications of diabetes mellitus, DME requires long-term management. This article aims to review the current challenges associated with the long-term management of DME, opportunities to improve outcomes for patients, and to develop a treat-to-target strategy based on macular morphology. At present, intravitreal anti-vascular endothelial growth factor (VEGF) therapy is the standard of care for the management of DME; however, best-achievable vision outcomes with treatment are reliant on frequent injections and close monitoring, which are difficult to maintain in current clinical practice because of the burden this imposes on patients. Achieving and maintaining good vision with treatment are the most important factors for patients with DME. Landmark trials have shown that vision gains with anti-VEGF therapy are typically accompanied by anatomical improvements (e.g., reductions in retinal thickness); therefore, multimodal imaging measures of macular morphology are often used in patients with DME to guide real-world treatment decisions. We would like to propose a hypothetical treat-to-target algorithm to guide physicians on treatment strategies for the long-term management of DME. Alternative measures of retinal fluid (e.g., persistence, stability, location) may be stronger predictors of visual acuity in DME, although further research is required to confirm whether alternate quantifiable biomarkers such as subretinal fluid and intraretinal fluid volumes can be used as a biomarker of clinical improvement. Identifying novel biomarkers and treatments that target neuroinflammation and neurodegeneration, improving patient-physician communication around treatment adherence, and using treat-to-target measures may help to ensure that the long-term benefits of treatment are realized.
RESUMO
Even in the post-coronavirus disease 2019 (COVID-19) era, it is prudent to exercise caution regarding the timing between intravitreal anti-vascular endothelial growth factor (VEGF) injections and COVID-19 vaccinations, as ocular inflammation can occur following both procedures. However, this perspective has not been sufficiently discussed thus far. Herein, we report a case of acute noninfectious anterior ocular inflammation following an intravitreal injection of ranibizumab biosimilar (RBZ BS, Senju Pharmaceuticals, Japan) in a patient recently vaccinated against COVID-19. A 74-year-old male with myopic choroidal neovascularization (CNV) in the left eye was treated with RBZ BS intravitreal injection. He received his fourth COVID-19 vaccination with messenger ribonucleic acid (mRNA)-1273 (Moderna) two days prior to his second RBZ BS intravitreal injection. He reported no systemic symptoms associated with the fourth COVID-19 vaccination. The second RBZ BS intravitreal injection was safely performed without complications. However, a few hours later, he experienced blurred vision without ocular pain in his left eye, a symptom not observed after the first injection. He visited a local ophthalmologic clinic the following day and was subsequently referred to our hospital due to anterior ocular inflammation in the left eye. His vision in the left eye was 0.3 decimal best-corrected visual acuity. Examination revealed non-granulomatous anterior ocular inflammation with 3+ cells and 2+ flare in the left eye. Anterior vitreous inflammation, keratic precipitates, or conjunctivitis was absent. Fundus examination also showed no signs of posterior inflammation. Both fluorescence angiography and indocyanine green angiography revealed staining corresponding to CNV without retinal vasculature leakage. There is nothing abnormal with the right eye based on the examination. Given that the noninfectious ocular inflammation was likely, based on the acute onset of symptoms within less than 24 hours following the RBZ BS intravitreal injection, and the presence of non-granulomatous inflammation only in the anterior segment without ocular pain, betamethasone eye drops four times daily was initiated in the left eye on the first day following the second RBZ BS intravitreal injection. Then, his ocular inflammation improved to mild by the fourth day post-injection. His eye eventually cleared, with no cells or flare in the anterior chamber at five months. Eventually, given the clinical course of good response to only topical steroid therapy, the diagnosis of noninfectious anterior ocular inflammation following RBZ BS in the case of a recent episode of COVID-19 vaccination was retrospectively confirmed. Although this case represents one of the initial instances of noninfectious ocular inflammation following RBZ BS (Senju Pharmaceuticals) administration, sterile ocular inflammation after other intravitreal anti-VEGF therapy has already been well-reported. In addition, given the recent COVID-19 vaccination, the ocular inflammation might be influenced by the vaccination, synergistically leading to vaccine-associated uveitis with similar signs and symptoms. In conclusion, to prevent such a complex situation, it is advisable to consider an adequate interval between COVID-19 vaccination and intravitreal anti-VEGF injections.
RESUMO
AIMS/INTRODUCTION: To conduct a multicenter survey of visually impaired patients with diabetes mellitus (DM) and to identify the physical and ocular characteristics that lead to blindness in Japan. MATERIALS AND METHODS: Visually impaired patients with diabetes mellitus in Japan were divided into blind and low-vision groups according to the World Health Organization classification. Data on parameters related to diabetes mellitus and ocular complications in the right and left eyes were collected from 19 highly advanced medical facilities and compared between the two groups. RESULTS: Among 408 visually impaired persons (blind group: 257, low-vision group: 151), 72.1% were under 70 years of age. The rates of neovascular glaucoma (NVG) (right eye, P = 0.041; left eye, P = 0.0031) or proliferative diabetic retinopathy (PDR) (right eye: P = 0.014, left eye: P = 0.0047) and the rate of proliferative membrane beyond half of the retinal area (right eye: P = 0.0263, left eye: P = 0.037) were significantly higher in the blind group. The direct cause of visual impairment was retinal atrophy, common in both groups. Neovascular glaucoma and diabetic macular edema were equally prevalent in the blind and low-vision groups, respectively. CONCLUSIONS: In Japan, blind patients with diabetes mellitus are characterized by severe conditions such as neovascular glaucoma and progressive proliferative diabetic retinopathy upon their initial visit to an advanced care facility. These results highlight the importance of monitoring retinopathy through regular ophthalmological examinations, internal medicine, and appropriate therapeutic intervention.

To investigate the association between lactate metabolism and glaucoma, we conducted a multi-institutional cross-sectional clinical study and a retinal metabolomic analysis of mice with elevated intraocular pressure (IOP) induced by intracameral microbead injection. We compared lactate concentrations in serum and aqueous humor in age-matched 64 patients each with primary open-angle glaucoma (POAG) and cataract. Neither serum nor aqueous humor lactate concentrations differed between the two groups. Multiple regression analysis revealed that only body mass index showed a significant positive correlation with serum and aqueous humor lactate concentration in POAG patients (rs = 0.376, P = 0.002, and rs = 0.333, P = 0.007, respectively), but not in cataract patients. L-Lactic acid was one of the most abundantly detected metabolites in mouse retinas with gas chromatography and mass spectrometry, but there were no significant differences among control, 2-week, and 4-week IOP elevation groups. After 4 weeks of elevated IOP, D-glucose and L-glutamic acid ranked as the top two for a change in raised concentration, roughly sevenfold and threefold, respectively (ANOVA, P = 0.004; Tukey-Kramer, P < 0.05). Glaucoma may disrupt the systemic and intraocular lactate metabolic homeostasis, with a compensatory rise in glucose and glutamate in the retina.

PURPOSE: To investigate the impact of using digital assisted vitrectomy (DAV) for color enhancement in color channel and achromatization in color profile on the visibility of indocyanine green (ICG)-stained internal limiting membrane (ILM). STUDY DESIGN: Retrospective observational study. METHODS: Twenty eyes from 20 patients (7 men, 13 women) who underwent 27-gauge pars plana vitrectomy for epiretinal membrane removal were included. The presettings of five different imaging modes of the NGENUITY® 3D visualization system (Alcon laboratories, Inc.), were adjusted, and intraoperative images of ILM removal were captured under each presetting. The color contrast ratios (CCR) between the ICG-stained ILM area and peeled ILM area were compared across presettings objectively. Subjective visibility of ILM in each patient for different presettings was ranked using a Likert scale and evaluated by five examiners. Data on sex, age, preoperative and postoperative best-corrected visual acuity (BCVA), preoperative and postoperative intraocular pressure (IOP), and postoperative complications were analyzed. RESULTS: Compared to other presettings the best CCR was achieved by adjusting the color channel to enhance red and by modifying the color profile to create a monochrome image (P<0.01). The same presetting resulted in a highest subjective visibility (P<0.01). Mean preoperative BCVA and 6-month postoperative BCVA (logMAR) were 0.11±0.18 and 0.05±0.19, respectively (p=0.24). Mean preoperative IOP and 6-month postoperative IOP were 13.8±2.8 mmHg and 13.3±3.4 mmHg, respectively (p=0.51). No apparent intra- and post-operative complications were observed. CONCLUSION: Color enhancement and achromatization using DAV may offer potential advantages to enhance the visibility of ICG-stained ILM.

PURPOSE: This pilot study aims to comprehensively evaluate the effects of sub-Tenon's injection of triamcinolone acetonide (STTA) on glycemic control in patients with diabetic macular edema (DME) using professional continuous glucose monitoring (CGM). METHODS: This retrospective study analyzed changes in glycemic control in 20 patients with type 2 mellitus and DME following single STTA (20 mg/0.5 mL) using The FreeStyle Libre Pro system. Professional CGM provides core CGM metrics such as the percentage of time that glucose levels fall within a target range and include the time in range (TIR) (70-180 mg/dL), time above range (TAR) (> 180 mg/dL), and time below range (TBR) (< 70 mg/dL). Outcome measures were the changes in CGM metrics (TIR, TAR and TBR) and the percentage of patients in whom TAR increased by at least 10 percentage points (ppt) 4 days before to 4 days after STTA administration. RESULTS: The mean CGM metrics (TIR/TAR/TBR) were 75.5%/19.9%/4.4% 4 days before STTA and 73.7%/22.4%/3.5% 4 days after STTA; the metrics 4 days before and 4 days after STTA were not significantly different (P = 0.625 for TIR, P = 0.250 for TAR, and P = 0.375 for TBR). TAR increased by more than 10 ppt in four (20%) patients treated with sulfonylurea and/or insulin. CONCLUSION: Although there were no significant changes in the CGM metrics, four patients developed CGM-measured hyperglycemia after STTA for DME.

PURPOSE: To investigate the incidence of intraocular inflammation (IOI) and its risk factors following intravitreal injections of brolucizumab for neovascular age-related macular degeneration in Japan. METHODS: A total of 1,351 Japanese consecutive patients with neovascular age-related macular degeneration who were treated with brolucizumab from May 2020 to May 2022 at 14 institutions were examined. The variables analyzed were the number of brolucizumab injections, time to onset of IOI, and risk factors. RESULTS: Intraocular inflammation developed in 152 eyes (11.3%). Retinal vasculitis and/or retinal occlusion occurred in 53 eyes (3.9%). Ninety-four patients received bilaterally, bilateral IOI occurred in five patients (5.3%). Sixteen eyes (1.2%) had irreversible visual acuity loss and nine eyes (0.67%) had visual loss of three lines or more due to retinal vasculitis and/or retinal occlusion. The cumulative IOI incidence was 4.5%, 10.3%, and 12.2% at 30, 180, and 365 days (1-year), respectively. History of IOI (including retinal vasculitis) and/or retinal occlusion (odds ratio [OR], 5.41; P = 0.0075) and female sex (OR, 1.99; P = 0.0004) were significantly associated with IOI onset. CONCLUSION: The 1-year cumulative incidence of IOI in Japanese neovascular age-related macular degeneration patients treated with brolucizumab was 12.2%. History of IOI (including retinal vasculitis) and/or retinal occlusion and female sex were significant risk factors.

This study investigated aniseikonia after reduced-fluence photodynamic therapy (RFPDT) for central serous chorioretinopathy (CSC). We examined 48 eyes of 48 patients (38 men; mean age, 49.2 ± 9.9 years) with CSC resolved after RFPDT. Horizontal and vertical aniseikonia were measured using the New Aniseikonia Test at baseline, 6 months, and 12 months after RFPDT. The maximum absolute value of the horizontal and vertical measurements indicated the aniseikonia score. The aniseikonia score was 2.2 ± 2.3 at 6 months and 2.2 ± 2.0 at 12 months after RFPDT, both of which improved significantly from the baseline score of 4.1 ± 2.9 (P < 0.05 and P < 0.01, respectively). The 12-month aniseikonia score significantly correlated with the baseline aniseikonia score (P = 0.047), outer nuclear thickness at baseline (P = 0.027) and 12 months after RFPDT (P = 0.014), baseline SRD area (P = 0.005), and ellipsoid zone disruption at 12 months after RFPDT (P = 0.021). In multivariate analysis, baseline serous retinal detachment (SRD) area (P = 0.034) was significantly associated with aniseikonia score at 12 months after RFPDT. Eyes with a larger SRD area might have higher aniseikonia scores even after SRD resolution following RFPDT.

INTRODUCTION: Astrocyte-to-neuron lactate shuttle (ANLS) plays an important role in the energy metabolism of neurons, including retinal ganglion cells (RGCs). Aquaporin 9 (AQP9), which is an aquaglyceroporin that can transport lactate, may be involved in ANLS together with monocarboxylate transporters (MCTs) to maintain RGC function and survival. This study aimed to investigate the impact of elevated intraocular pressure (IOP) on AQP9-MCT interaction and RGC survival. METHODS: IOP was elevated in Aqp9 knock-out (KO) mice and wild-type (WT) littermates by anterior chamber microbead injection. RGC density was measured by TUBB3 immunostaining on retinal flat mounts. Immunolabeling, immunoblot, and immunoprecipitation were conducted to identify and quantitate expressions of AQP9, MCT1, MCT2, and MCT4 in whole retinas and ganglion cell layer (GCL). RESULTS: Aqp9 KO and WT mice had similar RGC density at baseline. Microbead injection increased cumulative IOP by approximately 32% up to 4 weeks, resulting in RGC density loss of 42% and 34% in WT and Aqp9 KO mice, respectively, with no statistical difference. In the retina of WT mice, elevated IOP decreased the amount of AQP9, MCT1, and MCT2 protein and changed the AQP9 immunoreactivity and reduced MCT1 and MCT2 immunoreactivities in GCL. Meanwhile, it decreased MCT1 and increased MCT2 that interact with AQP9, without affecting MCT4 expression. Aqp9 gene deletion increased baseline MCT2 expression in the GCL and counteracted IOP elevation regarding MCT1 and MCT2 expressions. CONCLUSION: The compensatory upregulation of MCT1 and MCT2 with Aqp9 gene deletion and ocular hypertension may reflect the need to maintain lactate transport in the retina for RGC survival.

To evaluate the functional and anatomical effects of switching to faricimab for patients with neovascular age-related macular degeneration (nAMD) refractory to intravitreal aflibercept, this retrospective study evaluated patients with nAMD who received intravitreal injections of aflibercept (IVA) every <8 weeks and were switched to faricimab. After switching, the patients were treated with a treatment and extended regimen that started with the interval just before switching and received at least three injections. We evaluated changes in the best-corrected visual acuity (BCVA), central retinal thickness (CRT), central choroidal thickness (CCT), treatment interval, and presence of retinal fluid. Overall, 55 eyes from 55 patients were examined. After three injections of faricimab, the BCVA and CCT did not change significantly. However, the CRT decreased significantly (p < 0.05), the injection interval was significantly extended (7.5 ± 2.3 vs. 5.9 ± 1.5 weeks, p < 0.01), and the rates of the presence of intraretinal fluid and subretinal fluid decreased significantly to 16.4% and 40% of eyes, respectively (both p < 0.01). An ocular adverse event (retinal pigment epithelium tear) developed in one eye. Switching to faricimab was effective for anatomic changes. It may be an additional treatment option for some eyes refractory to IVA.
RESUMO
To report the usefulness of intraoperative real-time adjustment of intraocular lens (IOL) tilt during the intrascleral fixation with intraoperative optical coherence tomography (iOCT) as a clinical evaluation and investigate the factors contributing to IOL tilt using iOCT as an experimental evaluation. Retrospective cohort study and experimental research. As a clinical evaluation, the medical records of 43 eyes of 41 patients who underwent intrascleral IOL fixation combined with real-time iOCT observation were retrospectively reviewed. As an experimental evaluation, in order to investigate the factors contributing to IOL tilt, the four experiments were performed using iOCT. The mean IOL tilt angle (°) at the end of surgery and 3 months after surgery were 1.81 ± 1.15 and 2.10 ± 1.66, respectively (p = 0.46). No apparent intra- or postoperative complications occurred during the follow-up period. The experimental evaluation indicated that the IOL tilt was influenced by the insertion angle of the haptic in the vertical direction. The mean IOL tilt angle (°) was 1.94 ± 0.09, 4.67 ± 0.11, 8.90 ± 0.11, and 15.78 ± 0.85 when the insertion angle of the haptic was 0°, 10°, 27.5°, and 45° in the vertical direction, respectively (p < 0.01). Clinical and experimental IOL tilt assessment using iOCT is interactively useful for better quality surgery and better postoperative outcome.

PURPOSE: To compare the two-year outcome of half-time photodynamic therapy (htPDT) in chronic central serous chorioretinopathy (cCSC) with and without choroidal neovascularization (CNV). METHODS: In this retrospective study, we included 88 eyes of 88 patients with cCSC who underwent htPDT and were followed up for more than 24 months. Patients were divided into two groups with (21 eyes) or without (67 eyes) CNV before htPDT treatment. The best-corrected visual acuity (BCVA), central retinal thickness (CRT), subfoveal choroidal thickness (SCT), and the presence of subretinal fluid (SRF) were evaluated at baseline and at 1, 3, 6, 12, and 24 months after PDT. RESULTS: A significant intergroup difference was noted in terms of age (P = 0.038). Significant improvements in the BCVA and SCT were found at all time points in eyes without CNV but only at 24 months in eyes with CNV. CRT was significantly reduced in both groups at all time points. No significant intergroup differences were noted in terms of BCVA, SCT and CRT at all time points. There were significant differences in the rate of recurrent and persistent SRF between groups (22.4% (without CNV) vs. 52.4% (with CNV), P = 0.013, and 26.9% (without CNV) vs. 57.1% (with CNV), P = 0.017, respectively). The presence of CNV was significantly associated with the recurrence and persistence of SRF after initial PDT (P = 0.007 and 0.028, respectively). Logistic regression analyses showed that the baseline BCVA, and not the presence of CNV, was significantly associated with BCVA at 24 months after initial PDT (P < 0.01). CONCLUSIONS: A htPDT for cCSC was less effective in eyes with CNV than in those without CNV regarding the recurrence and persistence of SRF. Additional treatment might be required in eyes with CNV during 24-month follow-up periods.

The appropriate surgical technique to improve the closure rate of perioperative full-thickness macular hole (FTMH) secondary to submacular hemorrhage (SMH) with sub-internal limiting membrane (ILM) hemorrhage caused by retinal arterial macroaneurysm (RAM) rupture remains an unsolved clinical problem. Several ILM transplantation techniques have been attempted, but these are challenging. Our new technique can remove sub-ILM hemorrhage with the central fovea ILM intact, without peeling the ILM. The medical records of three eyes from three patients with SMH and sub-ILM hemorrhage secondary to RAM rupture were retrospectively reviewed. During the surgery, a small ILM fissure was made outside the central fovea with ILM forceps, and sub-ILM hemorrhage was washed out through it by manually spraying balanced salt solution. Sub-ILM hemorrhage removal was achieved successfully in all eyes, with no occurrences of FTMH or other complications. Best-corrected decimal visual acuity improved from 0.05 (Snellen equivalent (SE), 20/400), 0.05 (SE, 20/400), and 0.05 (SE, 20/400) preoperatively to 0.3 (SE, 20/63), 0.4 (SE, 20/50), and 0.15 (SE, 20/125) at 3 months postoperatively, respectively. This new technique may help keep the foveal ILM intact and prevent perioperative FTMH formation.
RESUMO
Background and Objectives: Faricimab is a novel bispecific antibody with Fab regions inhibiting both vascular endothelial growth factor-A and angiopoietin-2. Therefore, this study aimed to obtain short-term outcomes of intravitreal injection of faricimab (IVF) for the treatment of diabetic macular edema (DME) in daily clinical practice. Materials and Methods: A retrospective review was carried out on consecutive patients with DME who had been treated with IVF and were followed up for at least 1 month. Outcome measures included changes in logMAR best-corrected visual acuity (logMAR BCVA), central retinal thickness (CRT), number of IVF administrations, and safety. Clinical outcomes were also compared between the treatment-naïve and switch groups. Results: A total of 21 consecutive DME eyes from 19 patients were identified. The mean number of IVFs was 1.6 ± 0.8 during the mean follow-up time of 5.5 months. The overall mean logMAR BCVA following IVF was 0.236, 0.204, 0.190, and 0.224 at baseline, 1, 3, and 6 months, respectively, without a significant change from baseline to 1 month (p = 0.176) or for 6 months (p = 0.923). The overall mean CRT (µm) following IVF was 400.6, 346.6, 342.1, and 327.5 at baseline, 1, 3, and 6 months, respectively. CRT significantly decreased from baseline to 1 month (p = 0.001) but did not reach a significant level over 6 months following IVF (p = 0.070). No significant difference in BCVA or CRT was observed between the treatment-naïve and switch groups. No serious safety concerns were noted. Conclusions: IVF for the treatment of DME may preserve visual acuity and improve macular thickness without serious safety concerns in the short term in a real-world clinical setting.

PURPOSE: The aim of this study is to explore the clinical features and associated factors of intraocular inflammation (IOI) following intravitreal brolucizumab (IVBr) administration for neovascular age-related macular degeneration (nAMD). METHODS: This retrospective study included 87 eyes from 87 Japanese patients with nAMD who were followed up for 5 months after the initial administration of IVBr as switching therapy. Clinical pictures of IOI post-IVBr and changes in best corrected visual acuity (BCVA) at 5 months were evaluated between eyes with and without IOI (non-IOI). The association between IOI and baseline factors (age, sex, BCVA, hypertension, and/or arteriosclerotic changes in the fundus, subretinal hyperreflective material [SHRM], and macular atrophy) was evaluated. RESULTS: Of the 87 eyes, 18 (20.6%) developed IOI and 2 (2.3%) developed retinal artery occlusion. There were 9 (50%) cases of posterior or pan-uveitis among eyes with IOI. The mean interval from initial IVBr administration to IOI was 2 months. The mean changes in logMAR BCVA at 5 months were significantly worse in IOI eyes than in non-IOI eyes (0.09 ± 0.22 vs. - 0.01 ± 0.15, P = 0.03). There were 8 (44.4%) and 7 (10.1%) cases of macular atrophy and 11 (61.1%) and 13 (18.8%) cases of SHRM in the IOI and non-IOI groups, respectively. SHRM and macular atrophy were significantly associated with IOI (P = 0.0008 and P = 0.002, respectively). CONCLUSION: In IVBr therapy for nAMD, eyes with SHRM and/or macular atrophy should be observed more meticulously, given the increased risk of developing IOI, which is associated with insufficient BCVA gain.

PURPOSE: We have previously demonstrated that prolonged use of glaucoma medications was associated with a poor surgical outcome of ab interno trabeculotomy (µTLO). Given that almost all types of glaucoma eye drop either enhance the drainage through the uveoscleral pathway or reduce aqueous humor production, we hypothesized that prolonged use of these medications might cause disuse atrophy of the conventional pathway. In contrast, ripasudil increases the conventional outflow and eventually shows a favorable outcome of µTLO. This study aimed to evaluate the effect of ripasudil use on µTLO outcomes. METHOD: The medical charts of 218 patients who underwent µTLO were analyzed retrospectively. We compared the 1-year outcome between ripasudil users versus nonusers by using propensity score matching. We set the covariates as age, sex, glaucoma types, preoperative intraocular pressure (IOP), the mean deviation values of visual field tests, the presence or absence of concomitant cataract surgery, trabecular meshwork incision range, the presence or absence of any glaucoma medication except ripasudil and duration of glaucoma medical therapy. Success was defined as a postoperative IOP between 5 and 21 mmHg, a ≥ 20% IOP reduction from baseline, and no additional glaucoma surgery at postoperative 1 year. RESULT: Fifty-seven patients each were allocated to the ripasudil users or nonusers. The 1-year success rates were 74% in ripasudil users and 51% in nonusers (p = 0.01). KaplanâMeier survival curves also showed that the ripasudil users had a higher survival distribution (p = 0.01). CONCLUSION: The patients who took ripasudil showed a favorable 1-year outcome of µTLO.

Purpose: To evaluate the characteristics of posterior vitreous cells in patients with uveitis on the classification basis using spectral domain optical coherence tomography (SD-OCT). Methods: In this retrospective chart review, all eyes were classified into three groups: infectious uveitis (IFU, n=7), noninfectious granulomatous uveitis (NIGU, n=13), and noninfectious nongranulomatous uveitis (NINGU, n=13). We measured the size, number, and density of vitreous hyperreflective particles in the posterior vitreous area that was defined as the space between the vitreous top and the internal limiting membrane on OCT. The correlations between vitreous haze and vitreous particles were also evaluated. Results: Thirty-three eyes from 23 patients with active posterior uveitis were included. IFU had significantly more particles than NIGU and NINGU (P=0.03 and P<0.001, respectively). The vitreous particle density was higher in IFU than in NIGU and NINGU (P=0.03 and P=0.003, respectively). The mean largest particle size was greater in IFU and NIGU than in NINGU (P=0.01 and P=0.03, respectively). The median vitreous haze of 2+ in IFU, 1+ in NIGU and NINGU showed no significant difference among three groups (P=0.21). Conversely, the correlation of the largest particle size with vitreous haze was significant at ρ= 0.44 (P=0.01). Conclusion: SD-OCT may be useful for assessing ocular inflammation based on morphological characteristics of vitreous particles on the uveitis classification basis.
RESUMO
PURPOSE: We investigated potential risk factors for visual prognosis in Japanese patients with exogenous endophthalmitis. METHODS: In this retrospective observational multicenter cohort study, risk factors for legal blindness at 12 weeks after treatment initiation were evaluated based on patient characteristics, initial BCVA, causative events, pathogens, ocular symptoms, duration from symptom onset to initial treatment, and selected treatments. RESULTS: Overall, 23.1% of eyes developed legal blindness. The six risk factors for legal blindness were presence of eye pain, pathogen identification, poor BCVA at the initial visit, longer duration from symptom onset to initial treatment, type of causative event, and type of causative pathogen. Regarding the type of causative pathogen, coagulase-negative staphylococci was associated with a better visual impairment outcome. CONCLUSION: Exogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatment, as well as other advances in medical knowledge and technology.
RESUMO
A 38-year-old man with deep vein thrombosis associated with Behçet's disease (BD) was admitted to our hospital due to worsening symptoms despite the initiation of direct oral anticoagulants (DOACs). Administration of oral prednisolone and an intravenous anti-tumor necrosis factor-alpha (TNF-α) monoclonal antibody dramatically improved his symptoms. In addition, he was incidentally diagnosed with autosomal dominant polycystic kidney disease, which increases the risk of aortic aneurysms. BD also increases the risk of aortic aneurysms. This case suggests that immunosuppressive treatment is effective in patients with inflammation-related DOAC-refractory venous thrombosis who also suffer from BD.
