Abstract
INTRODUCTION Uveitis is a heterogeneous group of ocular conditions characterized by inflammation of the uveal tract and is one of the leading causes of vision impairment. In developed countries, noninfectious uveitis (NIU) represents most cases and is challenging to treat due to its severity, chronicity, and high recurrence rates. The advent of anti-tumor necrosis factor-α (anti-TNF-α) agents have dramatically improved outcomes and changed treatment paradigms in NIU. AREAS COVERED The index article summarizes the present experience of anti-TNF-α agents in NIU pharmacotherapy and highlights the barriers to further research and development of anti-TNF-α agents for uveitis. Common challenges faced in NIU clinical drugs trials, specific difficulties in anti-TNF-α drug development, and promising competitor drug candidates are discussed and evaluated. EXPERT OPINION Anti-TNF-α agents have revolutionized NIU pharmacotherapy and greatly improved outcomes with good safety profiles. The great success of systemic infliximab and adalimumab in NIU treatment has resulted in little impetus for further development of this class of medication. Attempts have been made to deliver anti-TNF-α agents intravitreally but that has not been successful thus far. With expiring patents, competition from biosimilars and newer, novel molecules, it may not be viable to continue pursuing anti-TNF-α drug development.

Abstract
OBJECTIVE To evaluate the functional implications of angiographic macular leakage without the presence of intraretinal fluid on optical coherence tomography (OCT) in eyes with intermediate, posterior, or panuveitis. METHODS Retrospective study on patients with a diagnosis of intermediate, posterior, or panuveitis. Patients who had fluorescein angiography, OCT, and multifocal electroretinography (mfERG) within a predetermined time frame were included. Demographic and clinical data including types of ocular inflammation and best-corrected visual acuity (BCVA), in addition to OCT, fluorescein angiography, and mfERG data were collected. The study cohort was divided into 2 groups based on the presence of angiographic macular leakage and macular edema (ME): group 1 (no ME and no macular leakage) and group 2 (presence of macular leakage without ME). RESULTS A total of 29 patients (43 eyes) were included in the study, with 13 patients (17 eyes) in group 1 and 16 patients (26 eyes) in group 2. No statistically significant differences in age, sex, anterior-chamber cells, lens status, vitreous cells, vitreous haze, BCVA, or mean central subfoveal thickness were found between groups 1 and 2. All mfERG values, including N1 and P1 response densities and timings for rings 1-5, did not show any statistically significant difference between group 1 and 2. No correlation was found between either BCVA or central subfoveal thickness and any of mfERG values for rings 1-3. CONCLUSIONS In absence of ME, angiographic macular leakage in eyes with uveitis might not be associated with worse macular function when compared with eyes without angiographic macular leakage.

Abstract
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.

Abstract
AIM To describe and correlate electroretinographic responses with clinical and angiographic findings in retinal vasculitis (RV). METHODS Medical records of patients with diagnosis of RV at a tertiary eye centre from December 2017 to May 2021 were reviewed. Cases in which fluorescein angiography (FFA) and full field electroretinography (ffERG) were done within 1 month were included. FFAs were graded according to the Angiography Scoring for Uveitis Working Group from 0 to 40, where 0 is normal. A novel ffERG grading system was implemented where individual waves were graded for timing and amplitude and general ffERG score was determined with 6 being a perfect score. RESULTS 20 patients (34 eyes) were included. Mean age was 43.9±19.8 years; 70% were female. Median best-corrected visual acuity was 0.8 (0.08-1). Mean FFA score was 12.6±6.5. Median general ffERG score was 5 (0-6). 68% and 91% of eyes had responses with general ffERG scores ≥5 and 4, respectively. Flicker timing was most commonly affected.FFA scores weakly correlated with delayed photopic cone b-wave and flicker timing (p=0.03 and 0.016, respectively). Vitreous haze moderately correlated with delayed cone b-wave timing (p<0.001), delayed flicker timing (p=0.002) and weakly correlated with lower flicker amplitude (p=0.03). Underlying systemic disease was associated with poor ffERG responses. CONCLUSION In this study, RV was not frequently associated with severe global retinal dysfunction Higher FFA scores, and vitreous haze grading were weakly, but significantly, correlated with cone-generated ffERG responses.

Abstract
BACKGROUND To describe longitudinal changes in patients with non-paraneoplastic autoimmune retinopathy (npAIR) by utilizing different diagnostic modalities/tests. METHODS The index study is a retrospective longitudinal review of sixteen eyes of eight patients from a tertiary care eye hospital diagnosed with npAIR. Multiple diagnostic modalities such as wide-angle fundus photography (WAFP), WA fundus autofluorescence (WAFAF), spectral-domain optical coherence tomography (SD-OCT), Goldmann visual field (GVF) perimetry, microperimetry (MP), electrophysiologic testing, and adaptive optics scanning laser ophthalmoscopy (AOSLO) were reviewed and analyzed. RESULTS At the baseline visits, anomalies were detected by multimodal diagnostic tests on all patients. Subjects were followed up for a median duration of 11.5 [3.0-18.7] months. Structural changes at the baseline were detected in 14 of 16 (87.5%) eyes on WAFP and WAFAF and 13 of 16 (81.2%) eyes on SD-OCT. Eight of the ten (80%) eyes that underwent AOSLO imaging depicted structural changes. Functional changes were detected in 14 of 16 (87.5%) eyes on GVF, 15 of 16 (93.7%) eyes on MP, and 11 of 16 (68.7%) eyes on full-field electroretinogram (ff-ERG). Multifocal electroretinogram (mf-ERG) and visual evoked potential (VEP) tests were performed in 14 eyes, of which 12 (85.7%) and 14 (100%) of the eyes demonstrated functional abnormalities, respectively, at baseline. Compared to all the other structural diagnostic tools, AOSLO had a better ability to demonstrate deterioration in retinal microstructures occurring at follow-ups. Functional deterioration at follow-up was detected on GVF in 8 of 10 (80%) eyes, mf-ERG in 4 of 8 (50%) eyes, and MP in 7 of 16 (43.7%) eyes. The ff-ERG and VEP were stable in the majority of cases at follow-up. CONCLUSIONS The utilization of multimodal imaging/tests in the diagnosing and monitoring of npAIR patients can aid in identifying anomalous changes over time. Analysis of both the anatomical and functional aspects by these devices can be supportive of detecting the changes early in such patients. AOSLO shows promise as it enables the capture of high-resolution images demonstrating quantifiable changes to retinal microstructure.

Abstract
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.

Abstract
PURPOSE To evaluate the efficacy of infliximab (IFX, 5-10 mg/kg) (Group 1) and tocilizumab (TCZ, 4-8 mg/kg) (Group 2) infusions in non-infectious retinal vasculitis (RV) using Angiographic Scoring for the Uveitis Working Group fluorescein angiography (FA) scoring system. METHODS Records of 14 patients (24 eyes) in Group 1 and 8 patients (11 eyes) in Group 2 were retrospectively evaluated to assess visual acuity (VA), anterior chamber cell and flare, vitreous haze, central subfield thickness (CST), and FA scoring at baseline and 6 months of follow-up. The measurements were employed to grade in each group. RESULTS In Group 1 and 2, respectively, there was no underlying disease in 9 (60%) and 3 (42.9%) patients. Three (42.9%) patients in Group 2 had juvenile idiopathic arthritis (JIA) as the most common identified cause. Mean improvement in VA (log MAR) and CST were 0.04 ± 0.14 and 40.3 ± 78.5 µm in Group 1; 0.04 ± 0.09 and 47.3 ± 82.3 µm in Group 2, respectively. Mean FA scores were significantly reduced from 12.4 ± 5.2 and 11.6 ± 4.4 at baseline to 6.4 ± 5.0 and 5.8 ± 3.9 at 6-month in Group 1 and 2, respectively. In Group 2, 9 eyes of 6 patients (75%) had the history of IFX use prior to TCZ initiation. There was no significant safety concern requiring treatment discontinuation during the follow-up in either group. CONCLUSION IFX and TCZ infusions showed statistically significant improvement of non-infectious RV as shown by ASUWOG FA Scoring System. TCZ, as well as IFX, appeared to be effective treatment options for non-infectious RV.

Abstract
PURPOSE Diopsys® NOVA™ is a novel full-field electroretinography (ffERG) device that can make rapid measurements of retinal electrophysiologic function. Diagnosys® Espion 2™ is a clinical gold-standard ERG device. This study aimed to investigate whether light-adapted Diopsys® NOVA™ fixed-luminance flicker ffERG magnitude and implicit time (converted from phase) measurements correlate with light-adapted Diagnosys® Espion 2™ flicker ffERG amplitude and implicit time measurements, respectively. METHODS Twelve patients (22 eyes) with various retinal and uveitic diseases underwent light-adapted Diagnosys® Espion 2™ and Diopsys® NOVA™ fixed-luminance flicker testing. Diopsys® magnitude and implicit time (converted from phase) measurements were compared to Diagnosys® amplitude and implicit time measurements, and a Pearson correlation was used to evaluate any existing correlation. Groups were also compared using generalized estimating equations. Bland-Altman plots were utilized to determine agreement between the comparison groups. RESULTS Age of patients ranged from 14 to 87 years. 58% (n = 7/12) of patients were female. A significant, positive correlation (r = 0.880, P < 0.001) was observed between magnitude (Diopsys®) and amplitude (Diagnosys®) measurements. Amplitude increases by 6.69 µV for each 1 µV increase in Magnitude (p-value < 0.001). A statistically significant, strong positive correlation was observed between Diopsys® implicit time measurements (converted from phase) and Diagnosys® implicit time measurements (r = 0.814, p-value < 0.001). For each 1 ms increase in Diopsys® implicit time, Diagnosys® implicit time increases by 1.13 ms (p-value < 0.001). CONCLUSIONS There is a statistically significant positive correlation between light-adapted Diopsys® NOVA™ fixed-luminance flicker amplitude and Diagnosys® flicker magnitude values. Additionally, there is a statistically significant positive correlation between Diopsys® NOVA™ fixed-luminance flicker implicit time (converted from phase) and Diagnosys® flicker implicit time values. These results imply that the Diopsys® NOVA™ module, which utilizes the nonstandard shortened International Society for Clinical Electrophysiology of Vision (ISCEV) ERG protocol, can produce reliable light-adapted flicker ffERG measurements.

Abstract
Purpose To present a case of birdshot chorioretinopathy (BCR) in a Chinese patient with HLA-A29 positivity. Observations A 45-year-old Chinese female presented at a tertiary Ophthalmology Clinic with complaints of frequent headaches as well as blurred vision, photophobia, and pressure in the left eye (OS). The patient had a significant ocular history of left orbital cavernous hemangioma status post lateral orbitotomy and resection. Uncorrected visual acuity was 20/20 in the right eye (OD) and 20/40 in OS (pinhole 20/30). Funduscopic examination demonstrated optic disc edema, left eye worse than right eye, and vascular tortuosity in both eyes (OU). Late phase fluorescein angiography (FA) showed extensive perivascular and optic disc leakage and peripheral capillary leakage in OU. Laboratory evaluations were positive for human leukocyte antigen-A29 (HLA-A29). The patient was started on 40 mg prednisone daily; mycophenolate mofetil 500 mg twice daily was subsequently added.At the 3-month consultation visit to the Uveitis Clinic, dilated funduscopic examination revealed 1+ vitreous cells and improved optic disc edema in OU. FA showed improved vascular and optic disc leakage in OS but worsened leakage in OD. At this point, indocyanine green angiography (ICGA) was ordered which revealed hypocyanescent lesions throughout the choroid that were centered on the optic disc, supporting and confirming the diagnosis of BCR. Conclusions and Importance The index patient is the first reported case of BCR in an HLA-A29 positive Asian patient.

Abstract
A 58-year-old male who underwent cataract extraction with combined intraocular lens and Hydrus® Microstent (Ivantis Inc, Irvine, CA, US) implantation 2 years ago in the right eye (OD) due to advanced glaucoma presented with blurry vision in right eye (OD) for 3 months. The visual acuity was 20/60 and slit-lamp examination indicated mild anterior chamber inflammation with unexposed, functioning tube shunt superotemporally in OD. Optical coherence tomography demonstrated cystoid macular edema (CME) with subretinal fluid. Fluorescein angiography demonstrated petaloid pattern leakage of CME. Gonioscopy revealed a kinked appearance of a Hydrus® Microstent protruding into the anterior chamber and causing iris chafing. Topical ketorolac tromethamine and prednisolone acetate were started. At the 2nd month of follow-up, the anterior chamber was quiet, and the CME resolved completely. Protruded kinked Hydrus® Microstent may lead to acute iridocyclitis and CME through iris chafing, which may be responsive to topical anti-inflammatory drops.

Abstract
Purpose Diopsys® NOVA fixed-luminance flicker full-field electroretinogram (ffERG) device is a potential adjunct to conventional flicker ffERG testing for assessing cone cell function. Magnitude of measured electrical response is known to vary with pupil size in conventional ffERG testing. The index study characterizes the relationship between magnitude of measured electrical activity and pupil size, both pupil diameter and pupil area, for this device. Methods Seventeen patients (34 eyes) with no known ocular diseases were enrolled in the study. Electrophysiologic function of cone cells was evaluated using fixed-luminance flicker ffERG before and after dilation. Linear regression models, with inter-eye correlations controlled as fixed-effects, were used to characterize the effect of pupil dilation on the magnitude of the measured responses. Results Mean age of study patients was 33.5 (standard deviation 7.4 years), and 35.3% of the subjects were female. Mean value of electrical response magnitude was 10.07±2.79µV before dilation and 15.30±4.08µV after dilation. The correlations of ERG magnitude with pupil diameter and with pupil area were not significant for either dilated or undilated eyes considered separately but were highly significant (p<0.001) for dilated and undilated eyes considered in aggregate. ERG magnitude tended to increase by 1.08 µV for every 1 mm increase in pupillary diameter. Conclusion An increase in pupil size, both pupil diameter and pupil area, is significantly associated with an increase in flicker ffERG magnitude recorded by the Diopsys device, suggesting that pupil size should be measured and considered when making clinical judgments based on the flicker ffERGs recorded by the device, and that pupil size-specific reference ranges could improve the clinical utility of the device.

Abstract
Purpose To present a case of acute anterior uveitis with macular edema associated with sildenafil citrate use in an HLA-B27 positive patient. Observations A 54-year-old Caucasian male presented at an ophthalmology tertiary center with complaint of pinkish discoloration, irritation, and photophobia in the left eye (OS). He noted that these symptoms appeared one day after using sildenafil for the first time to treat his erectile dysfunction. The patient had no significant ocular history besides refractive surgery in both eyes (OU) and his medical history was insignificant. Best-corrected visual acuity (BCVA) was 20/20 in the right eye (OD) and 20/25 in OS. Slit-lamp-examination (SLE) demonstrated trace cells and 1+ flare in the anterior chamber (AC) in OS and was nonrevealing in AC in OD. Spectral domain optical coherence tomography (SD-OCT) showed parafoveal subretinal hyperreflective deposits in OU. The patient was diagnosed with acute anterior uveitis (AAU) in the left eye and was placed on topical prednisolone acetate.At 2-week follow-up, the patient reported that his eye symptoms had improved since starting topical steroids but worsened again two days after he had used sildenafil for a second time. In OS, best-corrected visual acuity (BCVA) worsened to 20/40, and SLE revealed 1+ cells and 1+ flare in AC. SD-OCT revealed cystoid macular edema only in OS. Fluorescein angiography showed mild staining around the optic disc and significant macular leakage in OS and minimal macular leakage in OD. Uveitis evaluations revealed that the patient was human leukocyte antigen-27 (HLA-B27) positive. The patient was asked to remain off sildenafil and continue topical prednisolone acetate. At 3-month follow-up, BCVA improved to 20/20 in OS with no evidence of active inflammation. Conclusions and importance Sildenafil citrate use might be associated with new onset of intraocular inflammation in predisposed patients. Further studies are necessary to establish this relationship.

Abstract
Purpose To describe structural changes in corneal epithelium using anterior segment optical coherence tomography (AS-OCT) in two relapsed and refractory multiple myeloma (RRMM) patients with bilateral belantamab-associated superficial keratopathy (BASK). Observations case 1 A 56-year-old male who was diagnosed with RRMM and initiated on belantamab mafodotin, presented on day 42 (three weeks after the second infusion) with decreased pinhole visual acuity from 20/20 and 20/25 to 20/70 and 20/50 in the right eye and left eye, respectively. Slit-lamp examination revealed moderate superficial keratopathy with microcystic-like epithelial changes (MECs) in the paracentral cornea in both eyes. AS-OCT demonstrated increased bilateral heterogeneous signal intensity and hyperreflective lesions as well as increased thickness in the paracentral corneal epithelium with uninvolved central cornea. Given bilateral MECs, the third infusion was withheld, and then given on day 62 after five weeks of drug-free interval. Although MECs had improved on day 82, pinhole visual acuity remained at 20/50 and 20/40 in the right eye and the left eye. AS-OCT showed that hyperreflective lesions mostly resolved and corneal epithelial thickness returned to baseline, despite a slightly increased persisting heterogeneous signal intensity in the peripheral corneal epithelium in both eyes. Case 2 A 77-year-old male with RRMM was started on belantamab mafodotin infusions. His pinhole visual acuity decreased from 20/40 and 20/30 at baseline to 20/60 and 20/40 on day 41 (three weeks after the second infusion) in the right eye and left eye, respectively. Slit-lamp examination showed diffuse, moderate MECs in both eyes, which was more severe in the peripheral cornea. AS-OCT demonstrated increased bilateral heterogeneous signal intensity and hyperreflective lesions in the corneal epithelium, which are more severe in the right eye along with increased corneal epithelial thickness. Therefore, belantamab mafodotin was withheld. Conclusions and Impotance AS-OCT objectively demonstrated structural changes such as signal intensity and thickness alterations with hyperreflective lesions in the corneal epithelium related to BASK. AS-OCT might be useful for clinicians to monitor ocular surface adverse events in RRMM patients receiving belantamab mafodotin and to adjust therapeutic plans for the patients.
