Abstract
PURPOSE Vemurafenib, a BRAF inhibitor, has revolutionized the prognosis of late-stage melanoma patients, rising at the same time concerns about its potential adverse effects. Here is a case of vemurafenib-induced uveitis, peculiar in both its presentation and management. METHODS Case report, diagnostic, and therapeutic challenge. RESULTS Uveitis is a known side effect of vemurafenib. It is generally bilateral, moderate, manageable with topical steroids, and does not require cancer therapy cessation. We present a patient who suffered from a unilateral, severe uveitis after vemurafenib treatment that fully recovered thanks to intravitreal methotrexate injections because conventional corticosteroid therapy was contraindicated. CONCLUSION Uveitis can be a serious ocular adverse effect of vemurafenib, whereas its risk factors and mechanisms remain unknown. As BRAF inhibitors are now used on a regular basis, it is important for clinicians to be aware of this potentially sight-threatening side effect. Intravitreal methotrexate injections may be considered as an effective treatment choice in severe targeted agents-induced uveitis.

Abstract
Subretinal hyperreflective material (SHRM) is a common and remarkable optical coherence tomography (OCT) biomarker whose importance is emerging in several retinal and chorioretinal diseases, including age-related macular degeneration, central serous chorioretinopathy, polypoidal choroidal vasculopathy, pathologic myopia, posterior uveitis, vitelliform lesions and macular dystrophies, and rarer disorders. Multimodal imaging, also thanks to the introduction of OCT angiography, allowed a deeper characterisation of SHRM components and its morphological changes after treatment, suggesting its usefulness in clinical practice. We discuss and summarize the nature, multimodal imaging characteristics, and prognostic and predictive significance of SHRM in the different retinal and choroidal disorders in which it has been described.

OPHTHALMOLOGY SCIENCE 2024; 4:100403. [PMID: 38027419 PMCID: PMC10630780 DOI: 10.1016/j.xops.2023.100403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 09/08/2023] [Accepted: 09/11/2023] [Indexed: 12/01/2023]
Abstract
Objective To examine the long-term efficacy and safety of the intravitreal 0.2-μg/day fluocinolone acetonide implant (FAi) to treat noninfectious uveitis (NIU) of the posterior segment (PS). Design Three-year, phase III, multicenter, randomized, double-masked, controlled, prospective study (clinicaltrials.gov, NCT02746991). Participants Overall, 153 patients in India with NIU-PS in ≥ 1 eye (with or without anterior uveitis) for ≥ 1 year who had ≥ 2 separate recurrences of uveitis requiring ocular injections or systemic therapy in the prior 12 months. Methods Patients were randomized 2:1 for baseline FAi or sham injection and monitored for main outcome measures. Main Outcome Measures Incidence and timing of uveitis recurrence, use of adjunctive therapy, best-corrected visual acuity, central foveal thickness, and monitoring of intraocular pressure (IOP)- and cataract-related events over 36 months. Results Overall, 153 patients (FAi, n = 101; treated sham, n = 52) were enrolled. Fluocinolone acetonide implant-treated eyes had significantly reduced uveitis recurrence rates versus treated sham (46.5% vs. 75.0%, respectively; P = 0.001) and a longer median time to recurrence (1116.0 [95% confidence interval, 847.00 to not evaluable] vs. 190.5 [95% confidence interval, 100.0-395.0] days for treated sham). Systemic adjunctive treatments were similar between groups, but fewer FAi-treated eyes required adjunctive injections (8.9% vs. 51.9% for treated sham). Visual outcomes were similar between groups, and residual macular edema was more common at 36 months in treated sham versus FAi-treated eyes (46.2% vs. 24.2%, respectively). The FAi-treated group had a lower central foveal thickness from month 12 onward. Intraocular pressure-lowering surgeries were stable in both groups, but, as expected, rates of IOP elevations were more frequent in the FAi-treated group than in the treated sham (IOP > 25 mmHg: 23.8% vs. 3.8%; IOP > 30 mmHg: 16.8% vs. 1.9%, respectively), and FAi-treated eyes had a higher incidence of cataract surgery than the treated sham (70.5% vs. 26.5%, respectively). Conclusions In patients with NIU-PS, the 0.2-μg/day FAi is associated with reduced-uveitis recurrence and increased time to first recurrence while controlling macular edema, maintaining stable IOP levels, and providing an expected safety profile, including a higher occurrence of cataract formation over 36 months.

Abstract
Behçet's uveitis (BU) is a debilitating manifestation of Behçet's disease, often requiring prompt and aggressive treatment to prevent vision loss. Glucocorticoids (GCS) serve as a first-line therapy for BU; however, their long-term, high-dose use can result in significant adverse effects. This review summarizes the efficacy, adverse effects, and advances in combination therapy involving GCS for the management of BU. We discuss the benefits and drawbacks of various GCS administration routes, including periocular and intravitreal injections, intravitreal sustained-release devices, and systemic therapy, highlighting the role of fluocinolone acetonide and dexamethasone as primary sustained-release formulations. Moreover, we underscore the importance of combining GCS with immunosuppressive drugs and biological agents to minimize adverse reactions and optimize therapeutic outcomes. The review concludes that, while GCS remain a crucial component of BU treatment, careful consideration of their administration and combination with other therapies is essential to achieve long-term remission and improved visual outcomes for patients with BU.

Abstract
Non-infectious uveitis (NIU) is a disorder with various etiologies and is characterized by eye inflammation, mainly affecting people of working age. An accurate diagnosis of NIU is crucial for appropriate therapy. The aim of therapy is to improve vision, relieve ocular inflammation, prevent relapse, and avoid treatment side effects. At present, corticosteroids are the mainstay of topical or systemic therapy. However, repeated injections are required for the treatment of chronic NIU. Recently, new drug delivery systems that may ensure intraocular delivery of therapeutic drug levels have been highlighted. Furthermore, with the development of immunosuppressants and biologics, specific therapies can be selected based on the needs of each patient. Immunosuppressants used in the treatment of NIU include calcineurin inhibitors and antimetabolites. However, systemic immunosuppressive therapy itself is associated with adverse effects due to the inhibition of immune function. In patients with refractory NIU or those who cannot tolerate corticosteroids and immunosuppressors, biologics have emerged as alternative treatments. Thus, to improve the prognosis of patients with NIU, NIU should be managed with different drugs according to the response to treatment and possible side effects.

Abstract
PURPOSE To study the types of uveitis examined in a hospital serving indigent populations in need of low-cost care. METHODS A retrospective chart review examined the electronic medical records of all patients with uveitis-related at Drexel Eye Physicians. Data collected included demographics, anatomic location of the uveitis, systemic disease associations, treatment modalities and insurance. Statistical analysis was performed using χ² or Fischer exact tests. RESULTS 270 patients (366 eyes) were included for analysis, 67% of patients identified as African American. Most eyes (95.3%, N = 349) were treated with topical corticosteroid drops, and only 6 (1.6%) received an intravitreal implant. Immunosuppressive medications were started in 24 patients (8.9%). Nearly 80% depended to some extent on Medicare or Medicaid Assistance for treatment coverage. There was no association between insurance type and use of biologics or difluprednate. CONCLUSION We found no association between insurance type and the prescription of medications for uveitis that should be used at home. There was a minimal number of patients prescribed medications for implantation in the office. The adherence of use of medications at home should be investigated.

Abstract
Purpose The present study aimed to assess the efficacy and safety associated to the treatment of patients with non-infectious posterior uveitis with intravitreal dexamethasone (DEX) implants in a real-world clinical setting. Patients and Methods This is a retrospective, single center analysis of the data from 29 patients with non-infectious posterior uveitis in whom 38 eyes were treated with dexamethasone intravitreal implants in routine clinical practice between January 2012 and October 2017. The parameters of visual acuity (VA), intraocular pressure (IOP) and central retinal thickness (CRT) were recorded 6 weeks after the first implant was administered, in accordance with the clinical guidelines for the use of these implants, and after a 6-month follow-up period. In addition, the formation of cataracts was evaluated at 12 months. Results Treatment with the DEX implant caused a significant improvement in the VA from baseline at 6 weeks in eyes treated with 2-6 implants and for eyes without cataracts. A significant decrease in CRT was observed relative to the baseline at 6 weeks for eyes treated with 1 and 2-6 implants, which was maintained at 6 months for those eyes treated with 2-6 implants. This significant improvement in CRT at 6 weeks and 6 months was evident in eyes with and without cataracts. During the study period, the IOP was found to increase significantly from baseline at 6 weeks in some eyes but this was managed topically, and no surgical intervention was necessary. Conclusion Intravitreal DEX implants represent an effective and safe therapy for the treatment of non-infectious uveitis in routine clinical practice, producing favorable visual and anatomical outcomes after the administration of just 2-6 DEX implants.

Abstract
Behçet's disease is a rare and poorly understood vasculitis affecting blood vessels of all types and sizes. Uveitis and oral and genital ulcers represent the typical clinical triad. Populations along the ancient trading route connecting the Mediterranean basin with the Middle and Far East are most affected. Up to a quarter of the cases has a pediatric onset, typically around puberty. The aim of the treatment is early intervention to control inflammation, with symptom relief and prevention of relapses, damage, and complications. The heterogeneous clinical presentation often requires a multidisciplinary and tailored approach. Ocular, neurological, gastrointestinal, and vascular involvement is associated with a worse prognosis and needs more aggressive treatments. In young patients with expected prolonged disease, treatment should also focus on preventive measures and lifestyle advice. In recent years, the pharmacological armamentarium has grown progressively, although only a limited number of drugs are currently authorized for pediatric use. Most evidence for these drugs still derives from adult studies and experience; these are prescribed as off-label medications and are only available as adult formulations. Corticosteroids frequently represent the mainstay for the management of the initial acute phases, but their potential serious adverse effects limit their use to short periods. Different conventional disease-modifying anti-rheumatic drugs have long been used. Many other biologic drugs targeting different cytokines such as interleukin-1, interleukin-6, and interleukin-17 and treatments with small molecules including the phosphodiesterase 4 and Janus kinase inhibitors are emerging as novel promising therapeutic agents. In recent years, a growing interest has developed around anti-tumor necrosis factor agents that have often proven to be effective in severe cases, especially in those with a gastrointestinal and ocular involvement.

Abstract
(1) Background: To determine the diagnostic value of vitreous cytology in patients with vitreoretinal lymphoma (VRL) and evaluate its diagnostic accuracy relative to that of other diagnostic tests. (2) Methods: In total, 38 eyes from 38 patients with VRL who underwent diagnostic vitrectomy and were followed up for at least 6 months were analyzed. The clinical manifestations and VRL diagnostic rates for all diagnostic tests were determined. (3) Results: The presence of vitreous cells/opacity was the most common ophthalmic finding (97.4%), followed by sub-retinal pigment epithelial infiltration (65.8%) and retinal hemorrhage (21.1%). The VRL diagnostic rates were 89.3% for interleukin (IL)-10 levels > 50 pg/mL; 82.1% for IL-10/IL-6 ratios > 1; 60.0% and 63.3% for immunoglobulin heavy chain and kappa light chain clonality assays, respectively; and 44.4% for vitreous cytology. The VRL diagnostic rate for vitreous cytology was significantly lower in the steroid pretreatment group than in the non-steroid pretreatment group (p = 0.007). (4) Conclusions: The VRL detection rate for vitreous cytology was lower than that for the other tests, especially in patients who received steroid pretreatment. These findings suggest that even if vitreous cytology findings are negative, other tests and characteristic fundus findings should be evaluated to confirm VRL diagnosis.

Abstract
Treatment of posterior eye diseases with intravitreal injections of drugs, while effective, is invasive and associated with side effects such as retinal detachment and endophthalmitis. In this work, we have formulated a model compound, rapamycin (RAP), in nanoparticle-based eye drops and evaluated the delivery of RAP to the posterior eye tissues in a healthy rabbit. We have also studied the formulation in experimental autoimmune uveitis (EAU) mouse model with retinal inflammation. Aqueous RAP eye drops were prepared using N-palmitoyl-N-monomethyl-N,N-dimethyl-N,N,N-trimethyl-6-O-glycolchitosan (Molecular Envelope Technology - MET) containing 0.23 ± 0.001% w/v RAP with viscosity, osmolarity, and pH within the ocular comfort range, and the formulation (MET-RAP) was stable in terms of drug content at both refrigeration and room temperature for one month. The MET-RAP eye drops delivered RAP to the choroid-retina with a Cmax of 145 ± 49 ng/g (tmax = 1 hour). The topical application of the MET-RAP eye drops to the EAU mouse model resulted in significant disease suppression compared to controls, with activity similar to dexamethasone eye drops. The MET-RAP eye drops also resulted in a reduction of RORγt and an increase in both Foxp3 expression and IL-10 secretion, indicating a mechanism involving the inhibition of Th17 cells and the up-regulation of T-reg cells. The MET-RAP formulation delivers RAP to the posterior eye segments, and the formulation is active in EAU.

Abstract
Systemic corticosteroids and immunosuppressant agents are the mainstay of therapy for non-infectious uveitis (NIU). However, the risks associated with systemic administration and the need of delivering an effective and safe anti-inflammatory treatment targeted to the site of inflammation have prompt the use of local therapy in the management of NIU. This review will analyse the different local treatment options available, including corticosteroids, anti-vascular endothelial growth factor (VEGF), methotrexate and the recent biologics.

Abstract
ABSTRACT Uveitic macular edema is a significant cause of visual impairment in most uveitis types. Treatment options of uveitis have advanced remarkably in recent years. Up to now, corticosteroids remain the mainstay of treatment. Nonsteroidal immunomodulators, and recently the biologic agents, which can reinforce efficacy and enable discontinuation or reduction of steroids to maintenance doses, are becoming increasingly popular in the management of uveitic macular edema. Several medications can be used in intraocular delivery and more and more sustained releasing implants are being developed. This review will briefly focus on the review of local therapy for the management of cystoid macular edema in uveitis, as many of these novel approaches are currently being evaluated in clinical trials.

Abstract
PURPOSE To review the current regimens and novel therapeutic modalities in various stages of research and development for the management of non-infectious posterior uveitis (NIPU). METHODS We performed a thorough review of current literature using PubMed, Google Scholar and Clinicaltrials.gov to identify the published literature about the available therapeutics and novel drugs/therapies in different stages of clinical trials. RESULTS The current management regimen for non-infectious posterior uveitis includes corticosteroids, immunomodulatory therapies and anti-metabolites. However, NIPU requires long-term management for efficacious remission of the disease and to prevent disease relapse. Long-term safety issues associated with steroids have led to efforts to develop novel therapeutic agents including biological response modulators and immunosuppressants. The current therapeutic agents in various stages of development include calcineurin inhibitors, biologic response modifiers and a more a comprehensive modalities like ocular gene therapy as well as novel drug delivery mechanisms for higher bioavailability to the target tissues, with minimal systemic effects. CONCLUSION Novel efficacious therapeutic modalities under development will help overcome the challenges associated with the traditional therapeutic agents.

Abstract
Purpose Drug delivery by intravitreal injection remains problematic, small agents and macromolecules both clearing rapidly. Typical carriers use microparticles (>2 μm), with size-related liabilities, to slow diffusion. We recently described cationic nanoparticles (NP) where conjugated Arg peptides prolonged residence in rat eyes, through ionic interaction with vitreal poly-anions. Here we extended this strategy to in vivo tracking of NP-conjugate (NPC) clearance from rabbit eyes. Relating t1/2 to zeta potential, and varied dose, we estimated the limits of this charge-based delivery system. Methods NPC carried covalently attached PEG8-2Arg or PEG8-3Arg pentapeptides, having known sequences from human eye proteins. Peptides were conjugated (61–64 per NPC); each NP/NPC also carried a cyanine7 tag (<0.5 dye/particle). In vivo imaging system (IVIS), after intravitreal injection, estimated NPC loss by 800-nm photon emission (745-nm excitation) at 1 to 3-week intervals following initial scan at day 10. Results NPC of 2Arg-peptides or 3Arg-peptides showed clearance t1/2 of 7 days and 17 days respectively, unconjugated NP t1/2 was <<5 days. Doses of 90, 180, and 360 μg of PEG8-2Arg NPC were compared. The lower doses showed dose-proportional day-10 concentration, and similar clearance. Higher early loss was seen with a 360-μg dose, exceeding rabbit vitreal binding capacity. No inflammation was observed. Conclusions This type of cationic NPC can safely increase residence t1/2 in a 1 to 3-week range, with dose <100 μg per mL vitreous. Human drug load may then range from 10 to 100 μg/eye, usefulness depending on individual drug potency and release rate, superimposed on extended intravitreal residence.

Abstract
PURPOSE To assess efficacy and safety of sarilumab, a human anti-interleukin-6 receptor antibody, for treatment of posterior segment noninfectious uveitis (NIU). DESIGN Randomized, double-masked, placebo-controlled, phase 2 study. PARTICIPANTS Fifty-eight patients (eyes) with noninfectious intermediate, posterior, or panuveitis. METHODS Eyes received treatment every 2 weeks for 16 weeks with subcutaneous sarilumab 200 mg or placebo. MAIN OUTCOME MEASURES The primary end point was the proportion of patients with ≥2-step reduction in vitreous haze (VH) on the Miami scale or with a reduction of systemic corticosteroids (prednisolone or equivalent) to a dose of <10 mg/day at week 16. Primary end point was based on VH evaluation by a central reading center. Investigator evaluation of VH was a prespecified, planned secondary analysis. RESULTS At week 16, proportion of patients taking sarilumab or placebo with ≥2-step reduction in VH or corticosteroid dose <10 mg/day was 46.1% vs. 30.0% (P = 0.2354) based on central reading center assessment of VH and 64.0% vs. 35.0% (P = 0.0372) based on investigator assessment of VH, respectively. In the subgroup of eyes with VH grade ≥2 at baseline, the mean VH reduction from baseline to week 16 was significantly greater with sarilumab vs. placebo regardless of assessment by the central reading center (-2.1 [n = 11] vs. -1.7 [n = 3], respectively; P = 0.0255) or investigator (-2.5 [n = 19] vs. -1.2 [n = 11], respectively; P = 0.0170). The mean best-corrected visual acuity gain from baseline to week 16 was greater with sarilumab vs. placebo in the overall population (8.9 vs. 3.6 letters, respectively; P = 0.0333) and in the subgroup of eyes with central subfield thickness (CST) ≥300 μm at baseline (12.2 [n = 13] vs. 2.1 [n = 7] letters, respectively; P = 0.0517). Corresponding changes in CST were -46.8 vs. +2.6 μm (P = 0.0683) in the overall population and -112.5 [n = 13] vs. -1.8 [n = 6] μm (P = 0.1317) in the subgroup of eyes with CST ≥300 μm at baseline, respectively. The most common ocular adverse events were worsening of uveitis (0 [placebo] and 3 [sarilumab] patients) and retinal infiltrates (1 [placebo] and 2 [sarilumab] patients). CONCLUSIONS Subcutaneous sarilumab may provide clinical benefits in the management of NIU of the posterior segment, especially in eyes with uveitic macular edema.

Abstract
The management of uveitis is challenging for most treating ophthalmologists. The treatment of uveitis often requires the use of high dose of systemic corticosteroid and immunosuppressive agents, which are almost always associated with potential side effects. Intravitreal medications have become a popular mode of drug administration in uveitis patients as they provide high volume of drug to the target tissues, eliminating the risk of systemic toxicity. There has been tremendous development in the intravitreal therapeutics over the last few years. With the advent of sustained-release technique, increasing patient compliance, biodegradable nature of the implant, and introduction of newer agents with better safety profile, the intravitreal medications have become more popular in recent years. This review presents evidence in the scientific literature supporting the use of intravitreal medications for the management of uveitis and its complications.

Abstract
In recent decades, the treatment paradigm for noninfectious intermediate uveitis, posterior uveitis, and panuveitis, a group of intraocular inflammatory diseases, has included systemic and local (periocular or intraocular) corticosteroids, biologics, and other steroid-sparing immunomodulatory therapy agents. Recently, an intravitreal formulation of sirolimus, an immunosuppressant that inhibits the mammalian target of rapamycin, a key regulator of cell growth in the immune system, was developed. On the basis of this mechanism and the local method of delivery, it was hypothesized that intravitreal sirolimus can improve ocular inflammation in patients with noninfectious intermediate uveitis, posterior uveitis, and panuveitis, with minimal systemic exposure and systemic adverse events (AEs). This review summarizes the pharmacokinetics, efficacy, and safety results of intravitreal sirolimus from 3 preclinical studies and 4 phase 1-3 clinical studies. Preclinical studies in rabbits showed that 22 to 220 μg intravitreal sirolimus results in sustained release of sirolimus in the vitreous for 2 months or more, with systemic concentrations below the threshold for systemic immunosuppression (approximately 8 ng/ml). Subsequently, 2 phase 1 studies (n = 50 and n = 30) established that intravitreal sirolimus improves ocular inflammation in humans. Further investigation in phase 2 and 3 studies (n = 24 and n = 347, respectively) suggested that 440 μg has the best benefit-to-risk profile. In the phase 3 study, the proportion of patients who showed complete resolution of ocular inflammation at month 5 was significantly higher in the 440-μg group than in the 44-μg group (22.8% vs. 10.3%; P = 0.025, Fisher exact test). In addition, 47 of 69 patients (68.1%) who were treated with systemic corticosteroids at baseline discontinued corticosteroid use at month 5. No sirolimus-related systemic AEs were reported in phase 1-3 studies. Collectively, these preclinical and clinical study data of intravitreal sirolimus support the therapeutic rationale of treating noninfectious uveitis with a local mammalian target of rapamycin inhibitor and suggest that 440 μg intravitreal sirolimus has the potential to be an effective and well-tolerated anti-inflammatory and corticosteroid-sparing treatment for noninfectious intermediate uveitis, posterior uveitis, and panuveitis.

Abstract
Background Sarcoidosis constitutes one of the leading causes of ocular inflammation. Chronic ocular sarcoidosis can affect any segment of the eye and its adnexa, producing a wide range of clinical manifestations and severity. If left untreated, permanent visual impairment or even blindness may ensue. Treatment approaches vary from topical therapy to systemic agents that induce immunosuppression to different levels according to disease severity. Objective To review the published literature on the management options for chronic ocular sarcoidosis and provide a comprehensive list of available treatment strategies, including the newer biologics. Summary Ocular disease remains a challenging aspect of sarcoidosis and may even be the presenting sign of the disease. Prompt and effective therapy may reverse visual damage and prevent permanent loss of vision. Because of the complexity of the disease, a multidisciplinary approach is often required, with a view to addressing both the ocular and other systemic manifestations of sarcoidosis. Recent data suggest that achieving overall optimal systemic control is of paramount importance in controlling eye inflammation as well. Cytotoxic immunosuppressive agents for refractory chronic ocular disease, as well as biologic anti-TNFα therapies, have advanced the management of chronic disease and should be considered corticosteroid-sparing strategies before the onset of significant steroid-induced morbidity.

Abstract
PURPOSE To analyze the safety and efficacy of sustained-release intravitreal dexamethasone implant (Ozurdex) in management of TB-associated multifocal serpiginoid choroiditis (MSC). METHODS Retrospective review of TB-associated MSC patients, treated with anti-TB therapy (ATT) and adjunctive intravitreal Ozurdex. RESULTS Nine eyes of six patients were included. Four patients required Ozurdex implant for progressive or new lesions following ATT and two for additional systemic contraindications to corticosteroids - hyperglycemia and uncontrolled hypertension, respectively. The mean time to resolution was 9.17 ± 7.71 weeks. The mean follow-up post-injection was 13.11 ± 6.05 months (median 12 months [range 6-24.5 months]). Only one of nine eyes developed recurrent MSC lesions and this was attributed to possible autoimmune etiology. Two eyes (22.2%) developed steroid-induced glaucoma - one required implant removal. CONCLUSIONS Sustained-release intravitreal dexamethasone is a safe and efficacious adjunctive anti-inflammatory therapy for TB-associated MSC patients with contraindication for systemic corticosteroids or requiring supplemental anti-inflammatory therapy.
