One-year outcomes and safety assessment of faricimab in treatment-naïve patients with neovascular age-related macular degeneration in Japan.

This multicentre retrospective study evaluated the 1-year outcomes and safety profile of faricimab in treatment-naïve patients with neovascular age-related macular degeneration (nAMD). Fifty-five patients (57 eyes) underwent loading therapy comprising three monthly faricimab injections. If dryness was achieved by the third month, subsequent treat-and-extend (TAE) follow-up continued at a minimum 8-week interval thereafter. If wet macula persisted at the third month, a fourth dose was administered, followed by the TAE regimen. After 1 year, improvements in visual acuity (0.44 ± 0.46 [baseline] to 0.34 ± 0.48; p < 0.01) and central foveal thickness (326 ± 149 [baseline] to 195 ± 82 µm; p < 0.0001) were significant. Dry macula, characterised by the absence of intraretinal or subretinal fluid, was achieved in 65% of cases. Treatment intervals varied, ranging from 8 to 16 weeks, with 44% of eyes extending to a 16-week interval, followed by 33% at 8 weeks, 16% at 12 weeks, 5% at 14 weeks, and 2% at 10 weeks. Notably, 50% of the polypoidal choroidal vasculopathy patients exhibited complete regression of polypoidal lesions between 12 and 15 months. Faricimab treatment in nAMD patients induced significant improvements in central vision and retinal morphology. Two cases of retinal pigment epithelial tears and one case of iritis were reported as ocular complications.

Efficacy, durability, and safety of faricimab up to every 16 weeks in patients with neovascular age-related macular degeneration: 2-year results from the Japan subgroup of the phase III TENAYA trial.

PURPOSE: To evaluate 2-year efficacy, durability, and safety of faricimab in the TENAYA Japan subgroup and pooled global TENAYA/LUCERNE cohort of patients with neovascular age-related macular degeneration (nAMD). METHODS: Subgroup analysis of TENAYA/LUCERNE (NCT03823287/NCT03823300): phase III, multicentre, randomised, active comparator-controlled, double-masked, non-inferiority trials. Treatment-naïve patients aged ≥ 50 years with nAMD were randomised (1:1) to intravitreal faricimab (6.0 mg up to every 16 weeks [Q16W] after 4 initial Q4W doses) or aflibercept (2.0 mg Q8W after 3 initial Q4W doses). Outcomes were assessed through year 2 for the TENAYA Japan subgroup (N = 133) and global pooled TENAYA/LUCERNE cohort (N = 1329). RESULTS: Vision and anatomic improvements achieved with faricimab at year 1 were maintained over 2 years and were generally comparable between the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Adjusted mean best-corrected visual acuity (BCVA) change from baseline at year 2 for the TENAYA Japan subgroup and global pooled TENAYA/LUCERNE cohort was +7.1 (3.7-10.5) and +4.4 (3.2-5.5) letters in the faricimab arm, respectively, and +5.2 (1.9-8.6) and +4.3 (3.1-5.4) letters in the aflibercept arm, respectively. At week 112, the proportion of faricimab-treated patients on Q16W dosing was 61.0% and 63.1% in the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Faricimab was well tolerated through year 2. CONCLUSION: Year 2 TENAYA Japan subgroup findings for faricimab were generally consistent with the pooled global TENAYA/LUCERNE results in patients with nAMD. Vision and anatomical benefits with faricimab were similar to those with aflibercept but with fewer injections.

Six-Year Outcomes in Subjects with Polypoidal Choroidal Vasculopathy in the EVEREST II Study.

INTRODUCTION: The EVEREST II study previously reported that intravitreally administered ranibizumab (IVR) combined with photodynamic therapy (PDT) achieved superior visual gain and polypoidal lesion closure compared to IVR alone in patients with polypoidal choroidal vasculopathy (PCV). This follow-up study reports the long-term outcomes 6 years after initiation of the EVEREST II study. METHODS: This is a non-interventional cohort study of 90 patients with PCV from 16 international trial sites who originally completed the EVEREST II study. The long-term outcomes were assessed during a recall visit at about 6 years from commencement of EVEREST II. RESULTS: The monotherapy and combination groups contained 41 and 49 participants, respectively. The change in best-corrected visual acuity (BCVA) from baseline to year 6 was not different between the monotherapy and combination groups; - 7.4 ± 23.0 versus - 6.1 ± 22.4 letters, respectively. The combination group had greater central subfield thickness (CST) reduction compared to the monotherapy group at year 6 (- 179.9 vs - 74.2 µm, p = 0.011). Fewer eyes had subretinal fluid (SRF)/intraretinal fluid (IRF) in the combination versus monotherapy group at year 6 (35.4% vs 57.5%, p = 0.032). Factors associated with BCVA at year 6 include BCVA (year 2), CST (year 2), presence of SRF/IRF at year 2, and number of anti-VEGF treatments (years 2-6). Factors associated with presence of SRF/IRF at year 6 include combination arm (OR 0.45, p = 0.033), BCVA (year 2) (OR 1.53, p = 0.046), and presence of SRF/IRF (year 2) (OR 2.59, p = 0.042). CONCLUSION: At 6 years following the EVEREST II study, one-third of participants still maintained good vision. As most participants continued to require treatment after exiting the initial trial, ongoing monitoring and re-treatment regardless of polypoidal lesion status are necessary in PCV. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01846273.

Six-month outcomes of switching from aflibercept to faricimab in refractory cases of neovascular age-related macular degeneration.

PURPOSE: To assess 6-month outcomes of switching from aflibercept to faricimab in eyes with refractory neovascular age-related macular degeneration (nAMD) previously requiring monthly injections. METHODS: This multicenter retrospective study examined nAMD eyes receiving monthly aflibercept injections switched to faricimab administered monthly up to 4 injections followed by injections at a minimum of 2-month intervals as per drug labeling. Data regarding age, sex, number of previous injections, treatment intervals, and best-corrected visual acuity (BCVA) were collected. Central retinal thickness (CRT), subfoveal choroidal thickness (SFCT), and maximal pigment epithelial detachment (PED) height were measured by optical coherence tomography. RESULTS: The study included 130 eyes of 124 patients. At 6 months, 53 eyes (40.8%) continued on faricimab treatment (Group 1), while 77 eyes (59.2%) discontinued faricimab for various reasons (Group 2) the most common being worse exudation. There were no significant differences between the two groups at baseline. In Group 1, CRT and SFCT significantly decreased at 1 month (P = 0.013 and 0.008), although statistical significance was lost at 6 months (P = 0.689 and 0.052). BCVA and maximal PED height showed no significant changes; however, mean treatment intervals were extended from 4.4 ± 0.5 weeks at baseline to 8.7 ± 1.7 weeks at 6 months (P < 0.001) in Group 1. No clear predictors of response were identified. CONCLUSION: Switching from aflibercept to faricimab allowed for extension of treatment intervals from monthly to bimonthly in roughly 40% of eyes, suggesting that faricimab may be considered in refractory nAMD cases.

A COMPARATIVE STUDY OF MEDIUM-SIZED MACULAR HOLE SURGERY WITH INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE VERSUS CONVENTIONAL PEELING.

PURPOSE: To investigate surgical results for medium-sized (251-400 µ m) macular holes (MHs). METHODS: This retrospective observational study involved 266 eyes of 262 consecutive patients who underwent internal limiting membrane (ILM) peeling (147 eyes in the ILM peeling group) or inverted ILM flap cover technique (119 eyes in the inverted flap group) for primary medium-sized full-thickness MHs. Macular hole associated with retinal detachment, recurrent MH, and traumatic MH were excluded. RESULTS: The primary closure rate for overall medium-sized MHs was 100% (119 of 119 eyes) in the inverted flap group, which was significantly higher than that (94.6% [139/147 eyes]; P = 0.010) in the ILM peeling group. Notably, even after adjusting for the minimum MH diameter, presence of high myopia, or preexisting posterior vitreous detachment, the primary closure rate was significantly better in the inverted flap group than in the ILM peeling group (Cochran-Mantel-Haenszel test, overall adjusted P = 0.006, 0.009, 0.005, respectively). The preoperative and postoperative restoration of the outer retinal layers and visual acuity were comparable between the inverted ILM flap and ILM peeling techniques. CONCLUSION: Primary closure for medium-sized MHs was significantly superior in the inverted flap group than in the ILM peeling group.

INCIDENCE AND RISK FACTORS OF INTRAOCULAR INFLAMMATION AFTER BROLUCIZUMAB TREATMENT IN JAPAN: A Multicenter Age-Related Macular Degeneration Study.

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.

Maximum carotid intima-media thickness and NT-pro BNP in association with retinal vein occlusion.

The purpose is to clarify the relationship between patients with retinal vein occlusion (RVO), maximal intima-media complex thickness (Max IMT), and N-terminal pro-brain natriuretic peptide (NT-proBNP), which is useful in assessing atherosclerosis. This was a retrospective observation, single center study. The patients were 86 RVO patients (male: female = 43:43, mean age 63.3 years), 25 with central retinal vein occlusion (CRVO) and 61 with branch retinal vein occlusion (BRVO), classified as ≧50 years old and <50 years old, Max IMT≧1.1 and less, NT-pro BNP≧55 and less. Results showed that Max IMT ≧1.1 was significantly more common in both the CRVO and BRVO groups at ≧50 years, and NT-pro BNP ≧55 was significantly more common in the CRVO group. Max IMT≧1.1 was seen in 80% of the BRVO group and in 85% of patients aged ≧50 years. Sixty-eight percent of patients in the CRVO group had Max IMT≧1.1, but none of those < 50 years had Max IMT≧1.1. Forty-eight percent of RVO patients had NT-pro BNP≧55, and significantly more patients had Max IMT≧1.1 than those who did not have NT-pro BNP more than 55 (p = 0.02). Multiple regression analysis with Max IMT as the dependent variable showed that age and NT-pro BNP were significantly associated with RVO (p = 0.015, 0.022). RVO patients were more likely to have a Max IMT≧1.1, which was associated with atherosclerosis. Max IMT and NT-pro BNP were also associated with RVO patients, so NT-pro BNP may be a marker of RVO.

Three-month outcomes of faricimab loading therapy for wet age-related macular degeneration in Japan.

This multicenter study aimed to assess the short-term effectiveness and safety of faricimab in treatment-naïve patients with wet age-related macular degeneration (wAMD) in Japan. We retrospectively reviewed 63 eyes of 61 patients with wAMD, including types 1, 2, and 3 macular neovascularization as well as polypoidal choroidal vasculopathy (PCV). Patients received three consecutive monthly intravitreal injections of faricimab as loading therapy. Over these 3 months, visual acuity improved gradually compared to baseline. Moreover, the central foveal thickness decreased significantly at 1, 2, and 3 months compared to baseline (p < 0.0001). At 3 months after initiation of faricimab therapy, a dry macula (defined as absence of intraretinal or subretinal fluid) was achieved in 82% of the eyes. Complete regression of polypoidal lesions was observed in 52% of eyes with PCV. Subfoveal choroidal thickness also decreased significantly at 1, 2, and 3 months compared to baseline (p < 0.0001). Although retinal pigment epithelium tears developed in two eyes, there were no other ocular or systemic complications observed during the 3 months of loading therapy. In conclusion, loading therapy using faricimab resulted in improved visual acuity and retinal morphology in Japanese patients with wAMD without particular safety issues.

Efficacy, durability, and safety of faricimab up to every 16 weeks in patients with neovascular age-related macular degeneration: 1-year results from the Japan subgroup of the phase 3 TENAYA trial.

PURPOSE: To evaluate the 1-year efficacy, durability, and safety of faricimab versus aflibercept in patients with neovascular age-related macular degeneration (nAMD) enrolled in the Japan subgroup of the TENAYA trial. STUDY DESIGN: TENAYA (NCT03823287) was a global, phase 3, multicenter, randomized, active comparator-controlled, double-masked, noninferiority, parallel-group, 112-week trial. After completion of global enrollment, additional patients were enrolled in the Japan extension of TENAYA. METHODS: Treatment-naïve patients aged ≥ 50 years with nAMD were randomized (1:1) to intravitreal faricimab 6 mg up to every 16 weeks (Q16W) after 4 initial Q4W doses based on disease activity at weeks 20 and 24 or aflibercept 2 mg Q8W after 3 initial Q4W doses. Primary endpoint was mean change in best-corrected visual acuity (BCVA) from baseline averaged over weeks 40, 44, and 48. Anatomical/durability outcomes were assessed. RESULTS: Overall, 133 patients were included in the TENAYA Japan subgroup analysis (faricimab, n = 66; aflibercept, n = 67). The adjusted mean (95% confidence interval) BCVA changes were + 7.1 (4.6‒9.7) and + 7.7 (5.2‒10.1) letters in the faricimab and aflibercept treatment groups, respectively. At week 48, 66.1%, 22.6%, and 11.3% of patients in the faricimab group were on Q16W, Q12W, Q8W and dosing intervals, respectively. Ocular adverse event rates were similar between treatment groups (faricimab, n = 14 [21.2%] versus aflibercept, n = 17 [25.4%]). CONCLUSION: The TENAYA Japan subgroup analysis showed that faricimab up to Q16W had sustained efficacy with an acceptable safety profile. These findings are consistent with the global TENAYA and LUCERNE findings.

Genome-Wide Association Study of Age-Related Macular Degeneration Reveals 2 New Loci Implying Shared Genetic Components with Central Serous Chorioretinopathy.

PURPOSE: To investigate the genetic architecture of age-related macular degeneration (AMD) in a Japanese population. DESIGN: Genome-wide association study (GWAS). PARTICIPANTS: Three thousand seven hundred seventy-two patients with AMD and 16 770 control participants from the Japanese population were enrolled in the association analyses. METHODS: We conducted a meta-analysis of 2 independent GWASs that included a total of 2663 patients with AMD and 9471 control participants using the imputation reference panel for genotype imputation specified for the Japanese population (n = 3541). A replication study was performed using an independent set of 1109 patients with AMD and 7299 control participants. MAIN OUTCOME MEASURES: Associations of genetic variants with AMD. RESULTS: A meta-analysis of the 2 GWASs identified 6 loci significantly associated with AMD (P < 5.0 × 10-8). Of these loci, 4 were known to be associated with AMD (CFH, C2/FB, TNFRSF10A, and ARMS2), and 2 were novel (rs4147157 near WBP1L and rs76228488 near GATA5). The newly identified associations were confirmed in a replication study (P < 0.01). After the meta-analysis of all datasets, we observed strong associations in these loci (P = 1.88 × 10-12 and P = 1.35 × 10-9 for meta-analysis for rs4147157 and rs76228488, respectively). When we looked up the associations in the reported central serous chorioretinopathy (CSC) GWAS conducted in the Japanese population, both loci were associated significantly with CSC (P = 4.86 × 10-3 and P = 4.28 × 10-3 for rs4147157 and rs76228488, respectively). We performed a genetic colocalization analysis for these loci and estimated that the posterior probabilities of shared causal variants between AMD and CSC were 0.39 and 0.60 for WBP1L and GATA5, respectively. Genetic correlation analysis focusing on the epidemiologically suggested clinical risk factors implicated shared polygenic architecture between AMD and smoking cessation (rg [the measure of genetic correlation] = -0.33; P = 0.01; false discovery rate, 0.099). CONCLUSIONS: Our findings imply shared genetic components conferring the risk of both AMD and CSC. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

Short-term results for brolucizumab in treatment-naïve neovascular age-related macular degeneration: a Japanese multicenter study.

PURPOSE: To investigate short-term treatment outcomes of intravitreal brolucizumab (IVBr) for treatment-naïve neovascular age-related macular degeneration (AMD) in a Japanese multicenter study. STUDY DESIGN: Retrospective case control study METHODS: The subjects were 58 eyes of 57 patients with neovascular AMD (43 men and 14 women, mean age 74.6 years) of whom 43 eyes of 42 patients completed initial loading of 3 monthly IVBr injections and were followed for more than 3 months. Best-corrected visual acuity (BCVA) changes, anatomical outcomes, and complications were investigated. RESULTS: Of the 43 eyes that completed loading doses, the AMD subtype was type 1 and type 2 macular neovascularization (MNV) in 51%, polypoidal choroidal vasculopathy (PCV) in 42%, and type 3 MNV in 7%. At 3 months after initiating treatment, BCVA significantly improved (P = 0.002) and central retinal thickness significantly decreased (P < 0.0001). At 3 months, complete retinal and subretinal fluid resolution was achieved in 91% of all eyes and complete regression of polypoidal lesions was achieved in 82% of PCV eyes. Iritis occurred in 8 eyes of 8 patients (14%), but resolved using topical or subtenon corticosteroid injection without visual loss in all cases. CONCLUSIONS: IVBr for treatment-naïve neovascular AMD was effective in the short-term, achieving significantly improved BCVA, good retinal fluid resolution, and a high rate of polypoidal lesion regression. However, iritis was noted in 14% of patients which may limit use of this drug.

One-Year Outcome of Intravitreal Tissue Plasminogen Activator, Ranibizumab, and Gas Injections for Submacular Hemorrhage in Polypoidal Choroidal Vasculopathy.

This study investigated one-year outcomes of treatment with one session of intravitreal recombinant tissue plasminogen activator, ranibizumab, and gas injections for submacular hemorrhage secondary to polypoidal choroidal vasculopathy (PCV). An extended study of a previous prospective trial of this treatment modality in PCV patients was conducted in 64 patients (64 eyes). Early Treatment Diabetic Retinopathy Study (ETDRS) score, central retinal thickness (CRT), and central pigment epithelial detachment thickness (CPEDT) before and 1, 3, and 12 months after treatment were analyzed. Mean ETDRS score increased from 58 at baseline to 64 letters (p = 0.0122), CRT decreased from 543 to 192 µm (p < 0.0001), and CPEDT decreased from 161 to 103 µm (p = 0.0668) at 3 months and were maintained until 12 months. Complications requiring reoperation occurred within one month in four eyes. Recurrence was observed in 46 eyes (72%), and 1.6 ± 1.5 (0−7) intravitreal aflibercept injections were given pro re nata. Univariate and multivariate analyses identified CPEDT as the pre- and post-treatment factor affecting 12-month ETDRS score (p < 0.0001). Improved visual acuity stabilized 3 months after treatment. Although 72% of patients experienced recurrence, an average of 1.6 aflibercept injections/patient maintained visual acuity up to 12 months. CPEDT was the most important factor associated with visual outcome.

Outcomes of Vitrectomy with Fovea-Sparing and Inverted ILM Flap Technique for Myopic Foveoschisis.

Surgical treatment of myopic foveoschisis (MF) can result in a macular hole in 11−17% of patients that may lead to poor visual outcomes and progression to macular hole retinal detachment. We evaluated the benefit of vitrectomy to treat MF using the inverted internal limiting membrane (ILM) flap and fovea-sparing ILM techniques. We studied 20 eyes of 20 patients (7 men, 13 women) with high MF (mean axial length, 29.3 ± 1.7 mm). MF was classified by optical coherence tomography findings: retinoschisis (7 eyes) or foveal detachment (13 eyes). Between October 2013 and June 2021, we performed vitreous surgery in all 20 patients, employing both techniques. Air tamponade was used in 4 eyes, SF6 gas in 10 eyes, and C3F8 gas in 6 eyes. All patients stayed in the face-down position for one full day postoperatively. Visual acuity and foveal contour were analyzed using optical coherence tomography before surgery and at 3 and 6 months postoperatively. LogMAR visual acuity was 0.46 before surgery, with a significant improvement at 3 months (0.34) and at 6 months (0.2) postoperatively (p = 0.024, p < 0.001, respectively). In all patients, the foveal contour showed improvement without macular hole formation after surgery. These results show that vitrectomy, performed using the inverted ILM flap and fovea-sparing ILM technique, is effective for treating MF.

Incidence and risk of advanced age-related macular degeneration in eyes with drusenoid pigment epithelial detachment.

To investigate the incidence and risk of advanced age-related macular degeneration (AMD), including geographic atrophy (GA) and macular neovascularization (MNV), in eyes with drusenoid pigment epithelial detachment (PED). Eighty-five eyes with drusenoid PED from 85 patients (77.2 ± 7.0 years, male/female: 44/41) were included in this study. Patients were followed up every 1-3 months via spectral-domain optical coherence tomography (SD-OCT) and color fundus photography. If exudation was observed on SD-OCT, fluorescein and indocyanine green angiography were performed to confirm the MNV subtype accordingly. The maximum follow-up period was 60 months. During the study period, GA developed in 8 eyes while MNV also developed in 8 eyes. The Kaplan-Meier estimator revealed that the cumulative incidence for 60 months was 17.9% and 12.2% for GA and MNV, respectively. In eyes developing MNV, retinal angiomatous proliferation was the most common. Cox regression analysis revealed that baseline PED width was the only factor associated with advanced AMD. (p = 0.0026, Cox regression analysis). The 5-year cumulative incidence of advanced AMD, including GA and MNV, was approximately 30% in eyes with drusenoid PED among the Japanese elderly. A larger baseline PED width was the only risk factor for advanced AMD.

Progression of age-related macular degeneration in eyes with abnormal fundus autofluorescence in a Japanese population: JFAM study report 3.

PURPOSE: To evaluate the progression of early age-related macular degeneration to neovascular age-related macular degeneration (nAMD), and identify the abnormal fundus autofluorescence (FAF) patterns and markers of choroidal neovascularization (CNV) in fellow eyes of patients with unilateral nAMD. METHODS: Sixty-six patients with unilateral nAMD who developed abnormal FAF in the fellow eyes were enrolled in this multicenter, prospective, observational study, and followed-up for 5 years. FAF images on Heidelberg Retina Angiogram Digital Angiography System (HRA) or HRA2 were classified into eight patterns based on the International Fundus Autofluorescence Classification Group system. The patients in which the fellow eyes progressed to advanced nAMD, including those who did not develop nAMD, were assessed based on the following factors: baseline FAF patterns, age, sex, visual acuity, drusen, retinal pigmentation, baseline retinal sensitivity, family history, smoking, supplement intake, hypertension, body mass index, and hematological parameters. RESULTS: Of the 66 patients, 20 dropped out of the study. Of the remaining 46 patients, 14 (30.42%, male: 9, female: 5) progressed to nAMD during the 5-year follow-up. The most common (50% eyes) FAF pattern in the fellow eyes was the patchy pattern. According to the univariate analysis, CNV development was significantly associated with age, supplement intake, and low-density lipoprotein levels (p<0.05). Multivariable analysis revealed that patients who showed non-compliance with the supplement intake were more likely to develop nAMD (p<0.05). No significant association was found between the patchy pattern and CNV development (p = 0.86). CONCLUSION: The fellow eyes (with abnormal FAF) of patients with unilateral nAMD may progress from early to advanced nAMD. However, no FAF pattern was found that predicted progression in nAMD.

Bilateral Pachychoroid disease with type 3 Uveal effusion syndrome in one eye and central serous Chorioretinopathy in contralateral eye: a case report.

BACKGROUND: We report a case of bilateral pachychoroid disease with type 3 uveal effusion syndrome (UES) in one eye and central serous chorioretinopathy (CSC) in the contralateral eye. CASE PRESENTATION: A 65-year-old man presented to our department because of decreased vision. Visual acuity was 16/20 in the right eye and 2/20 in the left eye, with normal axial lengths. The left eye was diagnosed with CSC and underwent photocoagulation 8 years ago. The right eye showed inferior non-rhegmatogenous retinal detachment and peripheral choroidal detachment. Macular optical coherence tomography showed submacular fluid in the right eye, pachychoroid in both eyes, and choroidal thickness of 565 µm in the right and 545 µm in the left eye. In both eyes, fluorescence angiography showed window defects and mild fluorescence leakage, and indocyanine green angiography showed dilated choroidal vessels, mild choroidal hyperpermeability, and mild dye leakage. The left eye was diagnosed with chronic CSC. Initially, chronic CSC was also suspected in the right eye. However, photodynamic therapy failed, with worsened retinal detachment and visual acuity. Pachychoroid in the peripheral fundus (choroidal thickness 820 µm) was observed only in the right eye. Based on these findings, UES was diagnosed in the right eye. Sclerectomies were performed. The absence of scleral thickening and glycosaminoglycan deposition led to a final diagnosis of type 3 UES. The procedure was not effective, due to connective tissue regeneration at the sclerectomy sites. In the revision surgery, mitomycin-C was used with sclerectomies. One month after surgery, retinal and choroidal detachment disappeared, visual acuity recovered to 8/20, pachychoroid in the macula and peripheral fundus decreased, and choroidal thickness decreased to 352 µm in the macula and 554 µm in inferior peripheral fundus. CONCLUSIONS: Pachychoroid in the posterior pole was the common finding in type 3 UES and CSC, although extensive pachychoroid in the peripheral fundus may have caused retinal and choroidal detachment in the eye with type 3 UES. Full-thickness sclerectomies with mitomycin-C improved pachychoroid in the peripheral fundus and resolved retinal and choroidal detachment, clearly indicating that the sclera was the main cause of type 3 UES.

Safety Measures for Maintaining Low Endophthalmitis Rate after Intravitreal Anti-Vascular Endothelial Growth Factor Injection before and during the COVID-19 Pandemic.

During the COVID-19 pandemic, intravitreal injections are performed with patients wearing masks. The risk of endophthalmitis after intravitreal injection is reported to increase due to an influx of exhaled air containing oral bacteria from the upper part of the mask onto the ocular surface. We retrospectively investigated the incidence of endophthalmitis when intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections were performed using the same infection control measures before and during the pandemic. Vitreoretinal specialists performed intravitreal injections of anti-VEGF agents in the outpatient room of a university hospital. Infection control measures before and during the pandemic included covering the patient's eye with adhesive face drape and irrigating the ocular surface with 0.25% povidone-iodine before draping, and immediately before and after injection. Before the COVID-19 pandemic (February 2016 to December 2019), one case of endophthalmitis occurred among 31,173 injections performed (0.0032%; 95% confidence interval (CI), 0.000008-0.017872%). During the COVID-19 pandemic (January 2020 to August 2021), one case of endophthalmitis occurred among 14,725 injections performed (0.0068%; 95% CI, 0.000017-0.037832%). There was no significant difference between the two periods (Fisher's exact test: p = 0.5387). Even during the COVID-19 pandemic, very low incidence of endophthalmitis after intravitreal injection can be maintained by implementing basic infection prophylactic measures, including face draping and 0.25% povidone-iodine irrigation, established before COVID-19 pandemic.

Subfoveal choroidal thickness after brolucizumab therapy for neovascular age-related macular degeneration: a short-term multicenter study.

BACKGROUND/PURPOSE: Observation of choroidal thickness after anti-vascular endothelial growth factor (VEGF) therapy may be important for the ideal management of neovascular age-related macular degeneration (AMD). This study investigated changes in subfoveal choroidal thickness (SCT) during loading doses of intravitreal injections of brolucizumab in eyes with neovascular AMD. METHODS: This study included 73 eyes of 72 patients with neovascular AMD at five university hospitals in Japan. All 73 eyes underwent three monthly 6.0 mg intravitreal injections of brolucizumab at baseline, 1 month, and 2 months. The SCT at 3 months was evaluated using optical coherence tomography. RESULTS: The 73 eyes were classified into the treatment-naïve group (43 eyes) and the switched group (30 eyes) that were switched from other anti-VEGF treatments. After three intravitreal injections of brolucizumab, SCT significantly decreased from 236.5 ± 98.8 µm at baseline to 200.4 ± 98.3 µm at 3 months (percent of baseline 84.7%, P < 0.001) in the treatment-naïve group. In the switched group, SCT also significantly decreased from 229.0 ± 113.2 µm at baseline to 216.9 ± 110.2 µm at 3 months (percent of baseline 94.7%, P = 0.039), although the decrease was not as marked compared to that of the treatment-naïve group. CONCLUSION: Intravitreal injections of brolucizumab for neovascular AMD significantly reduced the SCT in both the treatment-naïve and switched groups. Brolucizumab may cause significant anatomic changes in the choroid, particularly in treatment-naïve AMD eyes, possibly more than that previously reported for other anti-VEGF agents.

The second Japanese family with Malattia Leventinese/Doyne honeycomb retinal dystrophy.

PURPOSE: To describe the clinical and genetic findings of patients in the second Japanese family with Malattia Leventinese/Doyne honeycomb retinal dystrophy (ML/DHRD). METHODS: Two patients (a 41-year-old male proband and his third son) underwent comprehensive ophthalmic examinations, including full-field and multifocal electroretinography (ERG). Sanger sequencing was performed to detect an EFEMP1 gene variant (p.Arg345Trp), which was identified as the only causative pathogenic variant. RESULTS: Genetic analysis revealed that both patients carried the heterozygous variant, but the other unaffected family members did not. Although the proband exhibited innumerable radially distributed drusen in both the posterior poles and good visual acuity at initial presentation, bilateral choroidal neovascularization (CNV) developed during the 15-year follow-up. The proband received 15 intravitreal anti-vascular endothelial growth factor (VEGF) injections in the left eye (LE) and two injections in the right eye (RE). At 56 years of age, his decimal best-corrected visual acuity was 0.1 and 1.2 in the LE and RE, respectively. Full-field ERG showed that while the rod and combined responses were within normal amplitudes, the cone and 30-Hz flicker responses had slightly decreased amplitudes. Multifocal ERG revealed attenuated central responses in the LE and decreased temporal responses in the RE. In the 20-year-old son, multifocal ERG showed normal responses in both eyes. CONCLUSION: This is the first report of ML/DHRD in a patient who developed bilateral CNV and received anti-VEGF treatment in both eyes. Although multifocal ERG exhibited worsening of macular function, the generalized photoreceptor function was preserved until middle age.
