The Surgical Outcomes of Modified Intraocular Lens Suturing with Forceps-Assisted Haptics Extraction: A Clinical and Basic Evaluation.

Background/Objectives: Postoperative intraocular lens (IOL) tilt is a risk associated with IOL scleral fixation. However, the cause of IOL tilt during IOL suturing remains unclear. Therefore, this study aimed to evaluate the surgical outcomes of a modified IOL suturing technique and investigate the factors contributing to postoperative IOL tilt and decentration. Methods: We included 25 eyes of 22 patients who underwent IOL suturing between April 2018 and February 2020. A modified IOL suturing technique that decreased the need for intraocular suture manipulation was used. Factors contributing to IOL tilt and decentration were investigated using an intraoperative optical coherence tomography (iOCT) system. Results: The mean postoperative best-corrected visual acuity improved from 0.15 ± 0.45 to -0.02 ± 0.19 (p = 0.02). The mean IOL tilt angle at the last visit after surgery was 1.84 ± 1.28 degrees. The present study reveals that the distance of the scleral puncture site from the corneal limbus had a stronger effect on IOL tilt; meanwhile, the suture position of the haptics had a greater effect on IOL decentration. Conclusions: The modified IOL suturing technique, which avoids intraocular suture handling, had favorable surgical outcomes with improved postoperative visual acuity and controlled IOL tilt and decentration. Accurate surgical techniques and careful measurement of distances during surgery are crucial for preventing postoperative IOL tilt and decentration.

Removal of Subinternal Limiting Membrane Hemorrhage Secondary to Valsalva Retinopathy Using a Fovea-Sparing Internal Limiting Membrane Fissure Creation Technique.

Introduction: Valsalva retinopathy can cause submacular hemorrhage (SMH), which may lead to visual disturbances. SMH can extend into the subinternal limiting membrane (ILM) and vitreous spaces, sometimes occurring concomitantly with full-thickness macular holes (FTMHs). Herein, we describe a case in which sub-ILM hemorrhage was removed without peeling the ILM of the central fovea, thus preserving the foveal ILM. Case Presentation: A 48-year-old female patient developed rapid-onset bilateral visual impairment due to SMH secondary to Valsalva retinopathy. The SMH predominantly consisted of sub-ILM hemorrhage. However, detailed observation was challenging due to the dense sub-ILM hemorrhage in the left eye. Initial best-corrected visual acuity (BCVA) in the right and left eyes were 1.2 and 0.03, respectively. Intravitreal tissue plasminogen activator (tPA) and sulfur hexafluoride (SF6) gas injections were initially administered to displace the SMH in the left eye; however, the SMH could not be successfully displaced. A vitrectomy was then performed. Intraoperatively, an ILM fissure beyond the foveal region was created using ILM forceps. The balanced salt solution was sprayed onto the ILM, and the sub-ILM hemorrhage was drained into the vitreous cavity from the ILM fissure. The surgery successfully displaced the sub-ILM hemorrhage while preserving the foveal ILM. No postoperative complications were observed. Visual acuity remained at 1.2 in the right eye and improved to 1.2 in the left eye 6 months postoperatively. Conclusion: Removing foveal sub-ILM hemorrhage without peeling the foveal ILM can be a viable treatment option to preserve the foveal ILM.

Acute Noninfectious Anterior Ocular Inflammation Following Ranibizumab Biosimilar Intravitreal Injection in a Patient With Recent COVID-19 Vaccination.

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.

The Role of Corticosteroids and Immunomodulatory Therapy in the Management of Infectious Uveitis.

PURPOSE: The index review aims to provide an update on the role of corticosteroids and steroid-sparing immunomodulatory therapy (IMT) in managing patients with infectious uveitis. METHOD: Narrative literature review. RESULTS: Corticosteroids and immunomodulatory therapy (IMT) focus on the host defense system instead of the pathogen, adjusting exaggerated inflammatory reactions to reduce potential harm to ocular tissues. Systemic or local corticosteroids are primarily selected as adjunctive medication for infectious uveitis. Concomitant corticosteroids have also been used in cases of paradoxical worsening in ocular tuberculosis and immune recovery uveitis in cytomegalovirus (CMV) retinitis. While there is no well-established evidence to support the use of IMT in infectious uveitis, it is occasionally used in clinical settings to treat persistent inflammation following resolution of infection such as cases of ocular tuberculosis and ocular syphilis where an insufficient response is observed with corticosteroids. CONCLUSION: There is no consensus on the position of immunomodulatory therapy in the management of infectious uveitis with different etiologies. The index review provides an overview of available adjunctive corticosteroids and IMT options to assist clinicians in managing such disease entities more efficiently.

Color enhancement and achromatization to increase the visibility of indocyanine green-stained internal limiting membrane during digitally assisted vitreoretinal surgery.

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.

Continuous glucose monitoring metrics following sub-Tenon's injection of triamcinolone acetonide for diabetic macular edema.

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.

Birdshot Chorioretinopathy in Early Adulthood: Review of Current Literature and Case Report.

Purpose: We describe the course of a patient diagnosed with birdshot chorioretinopathy (BSCR) in early adulthood and summarize clinical findings from similar BSCR patients reported in the literature. Observations: A 37-year-old male presented to our tertiary uveitis facility with bilateral ocular discomfort, hazy vision, and floaters. Ocular examination was notable for vitritis, optic disc edema, and ovoid hypopigmented chorioretinal lesions, visible on indocyanine green chorioangiography as multiple hypocyanescent spots in the intermediate phase. Full-field electroretinography and visual evoked potential showed global retinal dysfunction and optic nerve dysfunction. Laboratory evaluations were notable only for human leukocyte antigen (HLA)-A29 positivity. The patient was diagnosed with BSCR and started on oral prednisone and eventually managed with infliximab. Conclusions and Importance: BSCR can affect patients in early adulthood. Proper diagnostic work-up, including assessing HLA-A29 positivity, is needed to manage atypical cases.

Aniseikonia after reduced-fluence photodynamic therapy in patients with central serous chorioretinopathy.

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.

Short-Term Outcomes of Faricimab Treatment in Aflibercept-Refractory Eyes with Neovascular Age-Related Macular Degeneration.

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.

Pars plana vitrectomy with internal limiting membrane flap versus pars plana vitrectomy with conventional internal limiting membrane peeling for large macular hole.

BACKGROUND: Macular hole (MH) is a full-thickness defect in the central portion of the retina that causes loss of central vision. According to the usual definition, a large MH has a diameter greater than 400 µm at the narrowest point. For closure of MH, there is evidence that pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling achieves better anatomical outcomes than standard PPV. PPV with ILM peeling is currently the standard of care for MH management; however, the failure rate of this technique is higher for large MHs than for smaller MHs. Some studies have shown that the inverted ILM flap technique is superior to conventional ILM peeling for the management of large MHs. OBJECTIVES: To evaluate the clinical effectiveness and safety of pars plana vitrectomy with the inverted internal limiting membrane flap technique versus pars plana vitrectomy with conventional internal limiting membrane peeling for treating large macular holes, including idiopathic, traumatic, and myopic macular holes. SEARCH METHODS: The Cochrane Eyes and Vision Information Specialist searched CENTRAL, MEDLINE, Embase, two other databases, and two trials registries on 12 December 2022. SELECTION CRITERIA: We included randomized controlled trials (RCTs) that evaluated PPV with ILM peeling versus PPV with inverted ILM flap for treatment of large MHs (with a basal diameter greater than 400 µm at the narrowest point measured by optical coherence tomography) of any type (idiopathic, traumatic, or myopic). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane and assessed the certainty of the body of evidence using GRADE. MAIN RESULTS: We included four RCTs (285 eyes of 275 participants; range per study 24 to 91 eyes). Most participants were women (63%), and of older age (range of means 59.4 to 66 years). Three RCTs were single-center trials, and the same surgeon performed all surgeries in two RCTs (the third single-center RCT did not report the number of surgeons). One RCT was a multicenter trial (three sites), and four surgeons performed all surgeries. Two RCTs took place in India, one in Poland, and one in Mexico. Maximum follow-up ranged from three months (2 RCTs) to 12 months (1 RCT). No RCTs reported conflicts of interest or disclosed financial support. All four RCTs enrolled people with large idiopathic MHs and compared conventional PPV with ILM peeling versus PPV with inverted ILM flap techniques. Variations in technique across the four RCTs were minimal. There was some heterogeneity in interventions: in two RCTs, all participants underwent combined cataract-PPV surgery, whereas in one RCT, some participants underwent cataract surgery after PPV (the fourth RCT did not mention cataract surgery). The critical outcomes for this review were mean best-corrected visual acuity (BCVA) and MH closure rates. All four RCTs provided data for meta-analyses of both critical outcomes. We assessed the risk of bias for both outcomes using the Cochrane risk of bias tool (RoB 2); there were some concerns for risk of bias associated with lack of masking of outcome assessors and selective reporting of outcomes in all RCTs. All RCTs reported postoperative BCVA values; only one RCT reported the change in BCVA from baseline. Based on evidence from the four RCTs, it is unclear if the inverted ILM flap technique compared with ILM peeling reduces (improves) postoperative BCVA measured on a logarithm of the minimum angle of resolution (logMAR) chart at one month (mean difference [MD] -0.08 logMAR, 95% confidence interval [CI] -0.20 to 0.05; P = 0.23, I2 = 65%; 4 studies, 254 eyes; very low-certainty evidence), but it may improve BCVA at three months or more (MD -0.17 logMAR, 95% CI -0.23 to -0.10; P < 0.001, I2 = 0%; 4 studies, 276 eyes; low-certainty evidence). PPV with an inverted ILM flap compared to PPV with ILM peeling probably increases the proportion of eyes achieving MH closure (risk ratio [RR] 1.10, 95% CI 1.02 to 1.18; P = 0.01, I2 = 0%; 4 studies, 276 eyes; moderate-certainty evidence) and type 1 MH closure (RR 1.31, 95% CI 1.03 to 1.66; P = 0.03, I² = 69%; 4 studies, 276 eyes; moderate-certainty evidence). One study reported that none of the 38 participants experienced postoperative retinal detachment. AUTHORS' CONCLUSIONS: We found low-certainty evidence from four small RCTs that PPV with the inverted ILM flap technique is superior to PPV with ILM peeling with respect to BCVA gains at three or more months after surgery. We also found moderate-certainty evidence that the inverted ILM flap technique achieves more overall and type 1 MH closures. There is a need for high-quality multicenter RCTs to ascertain whether the inverted ILM flap technique is superior to ILM peeling with regard to anatomical and functional outcomes. Investigators should use the standard logMAR charts when measuring BCVA to facilitate comparison across trials.

A CASE OF RAPIDLY PROGRESSIVE RETINOPATHY ASSOCIATED WITH PEMBROLIZUMAB IMMUNOTHERAPY FOR METASTATIC UROTHELIAL CARCINOMA.

PURPOSE: To describe a novel case of bilateral rapidly progressive retinopathy after immunotherapy with pembrolizumab for metastatic urothelial carcinoma. METHODS: Case report. RESULTS: A 64-year-old man undergoing pembrolizumab immunotherapy was referred to our hospital because of bilateral acute vision loss. His best-corrected visual acuity was 20/30 in the right eye and 20/320 in the left eye, and a visual field test revealed central and paracentral scotomas in the right eye and central scotoma in the left eye. We suspected immune-related retinopathy based on the progressive photoreceptor damage with abnormal electroretinogram findings, absence of overt intraocular inflammation, and presence of malignancy. Cessation of pembrolizumab and steroid pulse therapy followed by decreasing oral prednisolone improved visual function and photoreceptor damage, although there was recurrence after pembrolizumab was restarted. CONCLUSION: We reported a case of rapidly progressive retinopathy that may have been triggered by pembrolizumab immunotherapy for metastatic urothelial carcinoma. High-dose corticosteroid pulse therapy was effective in reversing photoreceptor damage.

Usefulness of intraoperative optical coherence tomography to minimize the intraocular lens tilt during the intrascleral fixation: a clinical and experimental evaluation.

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.

ASSOCIATION OF ORAL MONTELUKAST WITH REDUCED ODDS OF DEVELOPING EXUDATIVE AGE-RELATED MACULAR DEGENERATION.

PURPOSE: This study was conducted to evaluate the association of oral montelukast, selective antagonism for cysteinyl leukotriene receptor 1, with reduced odds of exudative age-related macular degeneration (exAMD) development. METHODS: This case-control study was conducted using institutional cohort finder tool, and included 1913 patients with exAMD (ICD: H35.32 and 362.52) and 1913 age- and gender-matched control subjects without exAMD. Subanalysis among 1913 exAMD and 324 nonexudative AMD was also conducted. RESULTS: A total of 47 (2.5%) exAMD cases were identified to have a history of oral montelukast use before exAMD diagnosis, compared with 84 (4.4%) controls. Montelukast usage was significantly associated with reduced odds of exAMD in the multivariable analysis (adjusted odds ratio [OR]: 0.50, 95% confidence interval: 0.31-0.80) and nonsteroidal anti-inflammatory drug usage (adjusted OR: 0.69). Caucasian race, history of smoking, and nonexudative macular degeneration in either eye were also found to have a significant relationship with increased odds of exAMD. In the subanalysis, montelukast usage showed significant association with reduced odds of developing exAMD from nonexudative AMD (adjusted OR: 0.53, 95% confidence interval: 0.29-0.97) and the presence of atopic disease (adjusted OR: 0.60). CONCLUSION: The study results suggested that oral montelukast is linked to reduced odds of exAMD development.

Removal of Sub-Internal Limiting Membrane Hemorrhage Secondary to Retinal Arterial Macroaneurysm Rupture: Internal Limiting Membrane Non-Peeling Technique.

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.

Two-year outcome of half-time photodynamic therapy for chronic central serous chorioretinopathy with and without choroidal neovascularization.

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.

Short-Term Outcomes of Intravitreal Faricimab Injection for Diabetic Macular Edema.

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.

Clinical features and associated factors of intraocular inflammation following intravitreal brolucizumab as switching therapy for neovascular age-related macular degeneration.

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.

Characteristics of Cellular Infiltration into Posterior Vitreous in Eyes with Uveitis on the Classification Basis Assessed Using Optical Coherence Tomography.

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.
