RESUMEN
We report the familial occurrence of a severe phenotype of central serous chorioretinopathy (CSC). A 62-year-old man was referred to our institute to treat a macular lesion in his right eye. Best-corrected visual acuity (BCVA) in his right eye was 0.05 (decimal format). On the initial visit, swept-source optical coherence tomography (SS-OCT) demonstrated subretinal hyperreflective material (SHRM) and subretinal fluid involving the central macula in the right eye and a descending tract on fundus autofluorescence (FAF) in the left eye, and fluorescein angiography revealed focal leakage corresponding to choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA) of the right eye. He received photodynamic therapy (PDT) for the right eye and exudation disappeared. His 66-year-old elder brother had a medical history of CSC in both eyes and had received treatment at our hospital at 61 years old. On the initial presentation, ICGA showed multiple CVH in both eyes, and FAF showed hypofluorescence corresponding to retinal pigment epithelium (RPE) tears and RPE atrophy in both eyes. Bullous retinal detachment (RD) developed inferiorly in both eyes, and a vitrectomy was performed for the right eye to repair RD. The baseline BCVA was 0.3 in both eyes. Two years after the initial visit, recurrent serous RD developed in his left eye, and multiple PDT sessions were performed during the six-year follow-up. A severe phenotype of CSC may be associated with a genetic background.
RESUMEN
PURPOSE: We compared 12-month outcomes of eyes with polypoidal choroidal vasculopathy (PCV) with or without complete regression of polyps observed one month after three monthly intravitreal administrations (loading phase) of aflibercept (2.0 mg/0.05 mL) or brolucizumab (6.0 mg/0.05 mL). METHODS: All patients underwent indocyanine green angiography at both baseline and 3 months after initial injection and were followed up monthly with an as-needed regimen for up to 12 months. A total of 62 patients with PCV were included: 30 eyes were treated with brolucizumab, and 32 were treated with aflibercept. Eyes with complete regression of polyps (regression group) had significantly smaller maximum polyp diameter and were more frequently treated with brolucizumab than those without complete regression (non-regression) group. RESULTS: Best corrected visual acuity was comparable between the two groups at 12 months. Although the 12-month retreatment-free proportion was comparable between the two groups (33.0% versus 27.0%, p = 0.59), a retreatment-free period was significantly longer in the regression group than in the non-regression group (8.3 ± 3.3 versus 6.5 ± 3.6 months, p = 0.022), and the number of additional injections was significantly fewer in the regression group than in the non-regression group (1.2 ± 1.2 versus 3.0 ± 2.6, p = 0.007). CONCLUSIONS: Complete regression of polyps observed after the initial phase possibly prolongs the retreatment-free period and reduces the number of additional injections irrespective of aflibercept or brolucizumab.
RESUMEN
PURPOSE: To compare the genetic and clinical characteristics of central serous chorioretinopathy (CSC) in patients with and without steroid use. METHODS: A total of 407 consecutive patients with CSC were included. Demographic data and clinical factors, including subfoveal choroidal thickness, bilateral involvement, descending tracts, pachydrusen, fibrin, and dome-shaped pigment epithelial detachment, were obtained. Variants of complement factor H (CFH) I62V (rs800292) and rs1329428 were genotyped in all cases using TaqMan technology. RESULTS: Of the total patients, 48 (11.8%) were steroid users. The majority of males were non-steroid users (82.5%) than steroid users (58.3%) (p = 9.8 × 10-5). Demographic data and the prevalence of clinical factors were comparable between the two groups (all p-values > 0.10). Risk allele frequencies of CFH rs800292 and rs1329428 were also comparable between the two groups (p = 0.76, rs800292: steroid users = 52.1% vs. non-steroid users = 50.4%; p = 0.62, rs1329428: steroid users = 47.9% vs. non-steroid users = 45.3%). CONCLUSIONS: Except for the male/female ratio, there were no significant differences in the clinical presentation or genetic characteristics, including variants of the CFH gene, between the two groups.
RESUMEN
PURPOSE: To investigate the characteristics of patients with over a 12-month remission after 3 monthly intravitreal aflibercept injections followed by a pro re nata regimen for exudative age-related macular degeneration (AMD). METHODS: One hundred forty-four eyes with exudative AMD were included. All patients received 3 monthly intravitreal aflibercept injections as a loading dose, followed by an as-needed regimen for 60 months. Patients were classified into the remission and recurrence groups depending on the presence or absence of a 12-month remission. ARMS2 A69S and CFH I62V were genotyped in all cases. RESULTS: During the study, 82 eyes (56.9%) showed 12 months or more remission at least once. The cumulative incidence rate of a 12-month remission showed a plateau pattern and converged to 60% (y = -166.26x-2.172 + 0.6, R2 = 0.8168). Patients in the remission group were younger than those in the recurrence group (P < 0.001) and had less risk allele frequency of the ARMS2 gene than the recurrence group (P < 0.001). The longer the remission interval was prolonged, the better visual acuity was achieved at the 60-month visit (P < 0.001). CONCLUSION: Fifty-seven percent of patients showed a 12-month remission or more at least once during a 60-month follow-up, suggesting that patients with no reactivation can prolong the treatment interval.

The social impact of glaucoma is worth of note: primary open-angle glaucoma (POAG) is one of the leading causes of irreversible blindness worldwide, affecting some 68.56 million people with overall prevalence of 2.4%. Since one of the main risk factors for the development of POAG is the increase of intraocular pressure (IOP) causing retinal ganglion cells death, the medical treatment of POAG consists in the use of drugs endowed with neuroprotective effect and able to reduce IOP. These drugs include beta-blockers, prostaglandin analogues, carbonic anhydrase inhibitors, alpha or cholinergic agonists and rho kinase inhibitors. However, not all the patients respond to the same extent to the therapy in terms of efficacy and safety. Genetics and genome wide association studies have highlighted the occurrence of mutations and polymorphisms influencing the predisposition to develop POAG and its phenotype, as well as affecting the response to pharmacological treatment. The present systematic review and meta-analysis aims at identifying genetic variants and at verifying whether these can influence the responsiveness of patients to therapy for efficacy and safety. It follows the most updated Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 recommendations. The literature search was conducted consulting the most relevant scientific databases, i.e. PubMed/MEDLINE, Scopus, Web of Science and Public Health Genomics and Precision Health Knowledge Base up to June 14th, 2023. The search retrieved 1026 total records, among which eight met the eligibility criteria for inclusion in the analysis. The results demonstrated that the most investigated pharmacogenetic associations concern latanoprost and timolol, and that efficacy was studied more in depth than safety. Moreover, the heterogeneity of design and paucity of studies prompt further investigation in randomized clinical trials. In fact, adequately powered and designed pharmacogenetic association studies are needed to provide body of evidence with good certainty for a more appropriate use of medical therapy in POAG.PROSPERO registration: CRD42023434867.

PURPOSE: To compare the one-year visual and anatomic outcomes of an as-needed regimen of brolucizumab and aflibercept for polypoidal choroidal vasculopathy (PCV). STUDY DESIGN: A retrospective comparative study. METHODS: A retrospective medical chart review was performed for consecutive 56 eyes from 56 patients with PCV initially treated with thee monthly intravitreal aflibercept (n = 33, 2.0 mg/0.05 ml) or brolucizumab (n = 23, 6.0 mg/0.05 ml) followed by as-needed administration, followed up for at least 12 months. All patients were followed up monthly, and fluorescein and indocyanine green angiography (ICGA) were performed at baseline, 3-month, and 12-month visits. RESULTS: At the 12-month visit, best-corrected visual acuity significantly improved from 0.30 ± 0.31 to 0.21 ± 0.29 (p = 0.042) in the brolucizumab-treated group and from 0.24 ± 0.25 to 0.14 ± 0.25 (p = 7.7×10-3) in the aflibercept-treated group, suggesting comparable visual improvement in both groups. Central retinal thickness and subfoveal choroidal thickness decreased by 38.4% and 14.2%, respectively, in the brolucizumab-treated group and by 34.8% and 13.9%, respectively, in the aflibercept-treated group at the 12-month visit. The mean number of additional injections was significantly higher in the aflibercept-treated group (2.9 ± 2.7) than in the brolucizumab-treated group (1.3 ± 1.2, p = 0.045). The complete resolution of polypoidal lesions on ICGA was higher in the brolucizumab-treated group than in the aflibercept-treated group (3-month visit: 56.5% vs 30.3%, 12-month visit: 56.5% vs 30.3%). CONCLUSIONS: In treatment-naïve eyes with PCV, the as-needed administration regimen of brolucizumab was comparable to aflibercept in terms of visual and anatomical outcomes, with fewer additional injections during the 12-month follow-up.

We aimed to investigate whether a treat-and-extend regimen of intravitreal brolucizumab (6.0 mg/0.05 mL) is effective for eyes with exudative age-related macular degeneration (AMD) refractory to aflibercept for 12 months. Sixty eyes from 56 patients receiving brolucizumab for exudative AMD refractory to aflibercept were included. Patients received a mean of 30.1 aflibercept administrations for a mean 67.9-month follow-up. All patients exhibited exudation on optical coherence tomography (OCT) despite regular 4-8 weeks of aflibercept administration. Visit 1 was scheduled at the same interval from the last aflibercept injection to the baseline. The treatment interval was extended or shortened by 1-2 weeks depending on the presence or absence of exudation on OCT. After switching to brolucizumab, the follow-up interval significantly extended at 12 months (before switching: 7.6 ± 3.8 weeks vs. at 12 months: 12.1 ± 6.2 weeks, p = 1.3 × 10-7). Forty-three percent of the eyes achieved a dry macula at 12 months after switching. However, the best-corrected visual acuity did not improve at any visit. Morphologically, the central retinal thickness and subfoveal choroidal thickness significantly decreased from baseline at 12 months (p = 3.6 × 10-3 and 1.0 × 10-3, respectively). Switching to brolucizumab can be considered to extend the treatment interval in eyes with exudative AMD refractory to aflibercept.
RESUMEN
PURPOSE: To compare the clinical and genetic characteristics of simple and complex central serous chorioretinopathy using central serous chorioretinopathy international group criteria. METHODS: Patients with idiopathic central serous chorioretinopathy were included. Depending on the presence or absence of retinal pigment alterations greater than 2-disc areas in either eye, patients were classified into complex or simple types. Demographic factors and clinical findings were compared between groups. CFH variants, including rs800292 and rs1329428, were genotyped using TaqMan technology. RESULTS: A total of 319 consecutive patients were evaluated at the initial presentation. Of them, 53 (16.6%) had the complex type. The complex type was exclusively seen in men (100% vs. 79.0%, P = 2.0 × 10 -4 ) and demonstrated a significantly higher proportion of bilateral involvement (75.5% vs. 17.7%, P = 6.2 × 10 -18 ) and descending tract(s) (83.0% vs. 0%, P = 1.2 × 10 -57 ) than the simple type. Increased choroidal thickness (425 ± 131 vs. 382 ± 110, P = 0.02) and decreased central retinal thickness (274 ± 151 vs. 337 ± 136, P = 2.9 × 10 -4 ) were observed for the complex versus simple type. The risk allele frequencies of both variants were significantly higher in the complex versus simple type (rs800292: 61.3% vs. 48.7%, P = 0.018; rs1329428: 65.1% vs. 54.3%, P = 0.04). CONCLUSION: In this new classification system, the complex type has distinct genetic and clinical characteristics compared with the simple type.

Drusen are extracellular material considered a precursor lesion to advanced age-related macular degeneration (AMD), located either on the retinal pigment epithelium (RPE) or the sub-RPE; they contain various proteins associated with inflammation and lipids. Previous studies suggest that the lifecycle of drusen varies depending on drusen type and size. In general, conventional drusen grow and aggregate/coalesce in the first stage, and in the second stage, they regress with or without showing RPE atrophy. The risk of advanced AMD also varies depending on the drusen and drusenoid deposit types' along with their size and RPE abnormalities. In eyes with macular neovascularization (MNV), specific drusen/drusenoid deposits are closely associated with the MNV subtype. Recently, pachychoroid-associated drusen (pachydrusen) were proposed and clinical findings regarding this entity have been accumulating, as more attention is focused on drusen as well as pachychoroid diseases. With the advance in imaging modalities, various modalities can show specific characteristics depending on drusen types. To assess the risk of advanced AMD, it is essential for physicians to have accurate clinical knowledge about each druse/drusenoid lesion and correctly evaluate its imaging characteristics using multimodal imaging. This review summarizes the latest clinical knowledge about each druse/drusenoid lesions and documents their imaging characteristics on multimodal imaging, allowing clinicians to better manage patients and stratify the risk of developing advanced AMD. The most representative cases are illustrated, which can be helpful in the differential diagnosis of drusen and drusenoid deposits.

RATIONALE: Drusen are precursor lesions to advanced age-related macular degeneration. Although cuticular drusen are located between the retinal pigment epithelium and Bruch's membrane, as are conventional drusen, they possess unique characteristics that are distinct from those of conventional drusen on clinical presentations. Central serous chorioretinopathy (CSC) is a rare complication in eyes with cuticular drusen. PATIENT CONCERN: A 58-years-old man was referred to our institute for the treatment of persistent subretinal fluid (SRF) in both eyes. Spectral-domain optical coherence tomography revealed focal SRF that did not involve the central macula of the right eye and SRF in the central macula of the left eye. Fluorescein angiography exhibited focal leakage corresponding to SRF and hyperfluorescence resembling a "stars in the sky" appearance in both eyes. On initial presentation, the best-corrected visual acuity values were 1.2 and 0.9 in the right and left eye decimal formats, respectively. DIAGNOSIS: Cuticular drusen presenting with CSC in both eyes. INTERVENTIONS: No treatment was administered for CSC in the right eye, whereas photodynamic therapy was administered for CSC in the left eye. OUTCOMES: At the 6-month visit, extrafoveal SRF persisted in the right eye and resolved in the left eye. Best-corrected visual acuity improved from 0.9 to 1.2 in the decimal format in the left eye. LESSONS: Although cuticular drusen presenting with CSC are rare, physicians should be aware of the possibility of CSC development in eyes with cuticular drusen.

Primary open-angle glaucoma (POAG) is characterized by a progressive optic neuropathy with visual field loss. To investigate the genetic variants associated with visual field loss in POAG, Japanese POAG patients (n = 426) and control subjects (n = 246) were genotyped for 22 genetic variants predisposing to POAG that can be classified into those associated with intraocular pressure (IOP) elevation (IOP-related genetic variants) and optic nerve vulnerability independent of IOP (optic nerve-related genetic variants). The genetic risk score (GRS) of the 17 IOP-related and five optic nerve-related genetic variants was calculated, and the associations between the GRS and the mean deviation (MD) of automated static perimetry as an indicator of the severity of visual field loss and pattern standard deviation (PSD) as an indicator of the focal disturbance were evaluated. There was a significant association (Beta = - 0.51, P = 0.0012) between the IOP-related GRS and MD. The severity of visual field loss may depend on the magnitude of IOP elevation induced by additive effects of IOP-related genetic variants. A significant association (n = 135, Beta = 0.65, P = 0.0097) was found between the optic nerve-related, but not IOP-related, GRS and PSD. The optic nerve-related (optic nerve vulnerability) and IOP-related (IOP elevation) genetic variants may play an important role in the focal and diffuse visual field loss respectively. To our knowledge, this is the first report to show an association between additive effects of genetic variants predisposing to POAG and glaucomatous visual field loss, including severity and focal/diffuse disturbance of visual field loss, in POAG.

We aimed to investigate the characteristics and visual outcomes of farm work-associated eye injuries at vineyards. We retrospectively reviewed medical charts of patients with farm work-associated eye injuries. The eyes were divided into two groups according to the type of farming that contributed to the eye injury: the vineyard and other farming groups. Injury types, surgical procedures, and changes in visual acuity were statistically evaluated. After initial treatment, patients were followed up at different periods. We examined 30 eyes, including 14 eye injuries in the vineyard group and 16 eye injuries in the other farming group. The mean age of the patients was 58.8 ± 16.7 years, and 83.3% were male. None of the patients wore any safety eyewear at the time of injury. After initial treatment, the mean best-corrected visual acuity significantly improved from 0.83 ± 0.94 at baseline to 0.30 ± 0.57 at the final follow-up (p = 5.8 × 10-4). Eye injuries in the vineyard group were mostly caused by the penetration of wires of grape shelves and were frequent from winter to spring. We concluded that farm work-associated eye injuries at vineyards have characteristic properties compared with those during other farm work. The use of safety eyewear is strongly recommended to prevent eye injuries during farm work.
RESUMEN
Hyperreflective foci (HRF) are the findings observed in optical coherence tomography (OCT) in several retinal diseases and are believed to be associated with the increased risk of atrophy in eyes with age-related macular degeneration (AMD). In this study, we investigated the clinical and genetic characteristics of intermediate AMD with HRF. We reviewed the medical charts for 155 patients with intermediate AMD, in whom macular neovascularization (MNV) was observed in the contralateral eye. The presence or absence of an HRF was evaluated using a spectral-domain OCT volume scan spanning the macular region. Patients were followed longitudinally for at least 12 months, and the maximum follow-up period was 60 months. Genotyping of ARMS2 A69S and CFH I62V was performed in all participants. Of the 155 patients (mean age: 77.8 ± 7.6 years, male/female: 103/52), HRF was observed in 53 eyes (34.2%) and was significantly associated with type-3 MNV (p = 1.0 × 10-5) in the contralateral eye, pseudodrusen (p = 5.0 × 10-4), thinner subfoveal choroidal thickness (p = 0.013), and risk of ARMS2 A69S (p = 0.023). During follow-up (40.8 ± 17.5), 38 eyes (24.5%) developed advanced AMD. The mean time to the onset of advanced AMD was 29.8 ± 12.9 months in eyes with intermediate AMD. HRF was associated with MNV (p = 1.0 × 10-3), but not with atrophy.

To investigate the differences in clinical and genetic characteristics between males and females with central serous chorioretinopathy (CSC). Consecutive 302 patients (mean age; 56.3 ± 11.7, male/female: 249/53) with CSC were evaluated on the initial presentation. All CSC patients underwent fluorescein angiography and indocyanine green angiography (FA/ICGA), swept-source or spectral-domain optical coherence tomography (OCT), and fundus autofluorescence (FAF) to confirm a diagnosis. All patients were genotyped for rs800292 and rs1329428 variants of CFH using TaqMan technology. On the initial presentation, female patients were significantly older (p = 2.1 × 10-4, female 61.6 ± 12.4 vs male 55.1 ± 11.3) and had thinner subfoveal choroidal thickness (p = 3.8 × 10-5) and higher central retinal thickness (p = 3.0 × 10-3) compared to males. A descending tract was more frequently seen in males than in females (p = 8.0 × 10-4, 18.1% vs 0%). Other clinical characteristics were comparable between the sexes. The risk allele frequency of both variants including CFH rs800292 and CFH rs1329428 was comparable between males and females (CFH rs800292 A allele male 51.2% vs female 47.2%, CFH rs1329428 T allele male 56.2% vs 52.8%). On the initial presentation, age, subfoveal choroidal thickness and central retinal thickness differ between males and females in eyes with CSC. A descending tract may be a strong male finding in CSC.

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.

BACKGROUND/AIMS: To analyse the long-term anatomic and visual outcomes of patients with peripapillary pachychoroid syndrome (PPS), a recently described entity in the pachychoroid disease spectrum. METHODS: This study retrospectively included patients from several retina centres worldwide. Visual acuity (VA), retinal thickness and choroidal thickness at baseline, 6 months and final follow-up were assessed. Temporal trends in VA and anatomic characteristics were evaluated. Visual and anatomic outcomes in eyes that were observed versus those that were treated were analysed. RESULTS: Fifty-six eyes of 35 patients were included with mean follow-up of 27±17 months. Median VA was 20/36 at baseline and remained stable through follow-up (p=0.77). Retinal thickness significantly decreased subfoveally (p=0.012), 1.5 mm nasal to the fovea (p=0.002) and 3.0 mm nasal to the fovea (p=0.0035) corresponding to areas of increased thickening at baseline. Choroidal thickness significantly decreased subfoveally (p=0.0030) and 1.5 mm nasal to the fovea (p=0.0030). Forty-three eyes were treated with modalities including antivascular endothelial growth factor injection, photodynamic therapy, and others. VA remained stable in treated eyes over follow-up (p=0.67). An isolated peripapillary fluid pocket in the outer nuclear layer was characteristic of PPS. CONCLUSION: Patients with PPS experienced decreased retinal oedema and decreased choroidal thickening throughout the course of disease. While some patients experienced visual decline, the overall visual outcome was relatively favourable and independent of trends in retinal or choroidal thickening.

Hyperreflective foci (HRF) is a term coined to depict hyperreflective dots or roundish lesions within retinal layers visualized through optical coherence tomography (OCT). Histopathological correlates of HRF are not univocal, spacing from migrating retinal pigment epithelium cells, lipid-laden macrophages, microglial cells, and extravasated proteinaceous or lipid material. Despite this, HRF can be considered OCT biomarkers for disease progression, treatment response, and prognosis in several retinal diseases, including diabetic macular edema, age-related macular degeneration (AMD), retinal vascular occlusions, and inherited retinal dystrophies. The structural features and topographic location of HRF guide the interpretation of their significance in different pathological conditions. The presence of HRF less than 30 µm with reflectivity comparable to the retinal nerve fiber layer in the absence of posterior shadowing in diabetic macular edema indicates an inflammatory phenotype with a better response to steroidal treatment. In AMD, HRF overlying drusen are associated with the development of macular neovascularization, while parafoveal drusen and HRF predispose to macular atrophy. Thus, HRF can be considered a key biomarker in several common retinal diseases. Their recognition and critical interpretation via multimodal imaging are vital to support clinical strategies and management.
RESUMEN
We investigated the efficacy and safety of red (670 nm) subthreshold micropulse laser (SMPL) treatment for diabetic macular edema (DME) and compared the 1-year treatment outcomes of red and yellow (577 nm) SMPL for DME. A medical chart review was performed in 43 consecutive eyes of 35 patients who underwent red or yellow SMPL treatment for DME and were followed up for 12 months. There were 26 and 17 eyes in the yellow and red SMPL groups, respectively. The mean best-corrected visual acuity (BCVA) was maintained throughout the follow-up period of 12 months in the yellow and red SMPL groups (p = 0.39, p = 0.70, respectively). The central retinal thickness (CRT) measured by spectral-domain optical coherence tomography (SD-OCT) was significantly decreased at 12 months from baseline in the yellow and red SMPL groups (p = 0.047, p = 0.03, respectively). Although the amount of CRT reduction in the red SMPL group was significantly greater than that in the yellow SMPL group at 8 months from baseline (p = 0.02), the significance disappeared at the final follow-up period (p = 0.44). The red SMPL maintained the BCVA in patients with center-involving DME. The mean CRT in the red SMPL group significantly decreased, and the amount of CRT reduction was equivalent to that in the yellow SMPL group.
RESUMEN
RATIONALE: Brolucizumab is a novel anti-vascular endothelial growth factor agent with clinical trials demonstrating excellent efficacy for neovascular age-related macular degeneration (AMD) in both visual and anatomic outcomes. However, there is concern of intraocular inflammation (IOI), and we propose concurrent subtenon triamcinolone acetonide (STTA) to prevent IOI. PATIENT CONCERN: A 73-year-old man was treated with aflibercept for neovascular AMD in his right eye. Despite 11âmonths of monthly intravitreal aflibercept injections, optical coherence tomography demonstrated persistent exudation. Ten days following his second brolucizumab injection, the patient presented with decreased vision due to vitritis in his right eye. DIAGNOSIS: Brolucizumab-related IOI in neovascular AMD refractory to aflibercept. INTERVENTIONS: A combination therapy involving of intravitreal brolucizumab and STTA. OUTCOMES: The anti-vascular endothelial growth factor inhibitor was changed back to aflibercept; however, exudation persisted. Therefore, a combination therapy involving STTA (5âmg/0.5âmL) and intravitreal injection of brolucizumab (6.0âmg/0.05âmL) was performed to treat the exudation and as prophylaxis to recurrent IOI. Combination therapy achieved no recurrent IOI and resolution of exudation with 8-week treatment intervals. LESSONS: This case might indicate that STTA is not only an optimal treatment option for brolucizumab-related IOI but also a preventive agent for this condition.

We compared the short-term outcomes between 3-monthly aflibercept and brolucizumab injections for treatment-naïve polypoidal choroidal vasculopathy (PCV). A total of 52 eyes were included. Patients received 3 monthly intravitreal aflibercept (n = 38) or intravitreal brolucizumab (n = 14). Indocyanine green angiography (ICGA) was performed at baseline and at the 3-month visit. Selection of anti-VEGF agents depended on time. In the brolucizumab-treated group, best-corrected visual acuity (BCVA) improved from 0.27 ± 0.34 (log MAR unit) at baseline to 0.20 ± 0.24 at 3-month visit, which is comparable with the aflibercept-treated group (p = 0.87), after adjustment of confounding factors. Central retinal thickness significantly decreased by 43%-44% in both groups. Subfoveal choroidal thickness also significantly decreased by 20.5% during this interval in the brolucizumab-treated group, which was greater than the aflibercept-treated group. The complete resolution rate of polypoidal lesions on ICGA was significantly higher (p = 0.043) in the brolucizumab-treated group (78.6%) than in the aflibercept-treated group (42.1%). Intraocular inflammation was observed in 14.3% (2/14) in the brolucizumab-treated group only. In short-term follow-up, intravitreal injection of 3-monthly brolucizumab was comparable with aflibercept in terms of BCVA and morphological improvement along with higher resolution of polypoidal lesion(s) on ICGA.
