An international, expert-led consensus initiative to develop systematic, evidence-based recommendations for the treatment of noninfectious uveitis in the era of biologics. The availability of biologic agents for the treatment of human eye disease has altered practice patterns for the management of noninfectious uveitis. Current guidelines are insufficient to assure optimal use of noncorticosteroid systemic immunomodulatory agents. An international expert steering committee comprising 9 uveitis specialists (including both ophthalmologists and rheumatologists) identified clinical questions and, together with 6 bibliographic fellows trained in uveitis, conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol systematic review of the literature (English language studies from January 1996 through June 2016; Medline [OVID], the Central Cochrane library, EMBASE, CINAHL, SCOPUS, BIOSIS, and Web of Science). Publications included randomized controlled trials, prospective and retrospective studies with sufficient follow-up, case series with 15 cases or more, peer-reviewed articles, and hand-searched conference abstracts from key conferences. The proposed statements were circulated among 130 international uveitis experts for review. A total of 44 globally representative group members met in late 2016 to refine these guidelines using a modified Delphi technique and assigned Oxford levels of evidence. In total, 10 questions were addressed resulting in 21 evidence-based guidance statements covering the following topics: when to start noncorticosteroid immunomodulatory therapy, including both biologic and nonbiologic agents; what data to collect before treatment; when to modify or withdraw treatment; how to select agents based on individual efficacy and safety profiles; and evidence in specific uveitic conditions. Shared decision-making, communication among providers and safety monitoring also were addressed as part of the recommendations. Pharmacoeconomic considerations were not addressed. Consensus guidelines were developed based on published literature, expert opinion, and practical experience to bridge the gap between clinical needs and medical evidence to support the treatment of patients with noninfectious uveitis with noncorticosteroid immunomodulatory agents.

To describe the clinical and angiographic features of a series of patients with acute syphilitic posterior placoid chorioretinitis (ASPPC) in the context of previously published cases. A retrospective, noncomparative, multicenter chart review was performed on 16 patients with active ASPPC. Positive serologic tests supported the diagnosis in all patients. Color and red-free photographs as well as fluorescein angiography were obtained in each case. Indocyanine green angiography, optical coherence tomography, and fundus autofluorescence were performed on selected patients. A total of 44 previously published cases of ASPPC were identified using both a Medline Search and references listed in articles identified. Ocular involvement was bilateral in 9 of our 16 patients (56.3%). The mean and median ages at presentation were 40 and 38 years, respectively (range 28–57 years). Nine patients (56.3%) were human immunodeficiency virus positive, with most recent CD4 cell counts ranging from 160 cells/μL to 450 cells/μL and a median CD4 cell count of 250 cells/μL. Seven of 16 patients (43.8%) had a history of mucocutaneous manifestations of secondary syphilis, whereas 4 (25.0%) had evidence of neurosyphilis. Anterior chamber and/or vitreous inflammation was evident in 13 patients (81.3%). Fifteen of 16 patients had positive venereal disease research laboratory or rapid plasma regain titers, and 13 of 13 tested patients had a positive serum fluorescent treponemal antibody absorption. The initial vision in the 25 affected eyes ranged from 20/20 to counting fingers, with a median of 20/80. In all patients, posterior segment examination in the involved eyes revealed a large, yellowish, placoid, outer retinal lesion. Fluorescein angiography showed progressive hyperfluorescence in the area of the lesion, often with scattered focal hypofluorescence, or leopard spotting. Inflammation subsided, the yellowish lesions resolved, and vision improved shortly after antibiotic therapy in 20 of 25 affected eyes. Visual acuity at last visit ranged from 20/20 to 20/150, with a median final vision of 20/25. A review of the literature revealed 44 previously reported cases of ASPPC. Shared demographic, clinical, and angiographic features were summarized. Acute syphilitic posterior placoid chorioretinitis is an uncommon but clinically and angiographically distinct manifestation of ocular syphilis. All patients with characteristic clinical and angiographic findings of ASPPC should be tested for both neurosyphilis and human immunodeficiency virus coinfection. Vision recovery typically followed completion of appropriate antibiotic therapy.

To describe the appearance of acute syphilitic posterior placoid chorioretinitis, a rare ocular manifestation of syphilis, on spectral domain optical coherence tomography (SD OCT) both before and after treatment. Ophthalmic examination and imaging studies of 30 eyes of 19 confirmed cases were analyzed both at the time of presentation and at each follow-up visit. Patients with SD OCT and fluorescein angiography at the time of presentation, and at least three documented follow-up visits after initiation of therapy, were included in the study. Standard treatment of neurosyphilis was given to each patient, including 4 million units of penicillin G administered intravenously every 4 hours for 14 days. Fundus examination and imaging studies were consistent with previous reports and confirmed the diagnosis of acute syphilitic posterior placoid chorioretinitis. In 13 eyes (43.3%), baseline SD OCT scans were performed within 1 to 2 days of presentation and revealed a small amount of subretinal fluid, disruption of the inner segment/outer segment junction, and hyperreflective thickening of the retinal pigment epithelium (RPE). All 30 eyes were again scanned between Days 7 and 9 after presentation and revealed loss of the inner segment/outer segment and OS/RPE bands, and irregular hyperreflectivity of the RPE with prominent nodular elevations but without subretinal fluid. Early disruption of the external limiting membrane and punctate choroidal hyperreflectivity were seen in 1 of the 30 eyes (3.3%) and 14 of the 30 eyes (46.6%), respectively. Vision improved and the outer retinal abnormalities normalized in 28 of the 30 eyes (93.3%) after the treatment of neurosyphilis. The external limiting membrane, inner segment/outer segment band, and/or linear outer segment/RPE junction remained substantially abnormal despite treatment in 2 eyes left with 20/200 vision. Patients with acute syphilitic posterior placoid chorioretinitis show characteristic outer retinal abnormalities on SD OCT imaging, including disruption of the inner segment/outer segment band, nodular thickening of the RPE with loss of the linear outer segment/RPE junction, and, in some cases, loss of the external limiting membrane, accumulation of subretinal fluid, and punctate hyperreflectivity in the choroid. Vision improved and these abnormalities reversed after treatment of neurosyphilis in most of the patients. Persistently, poor vision despite treatment was associated with long-term loss or disruption of outer retinal anatomy on SD OCT.

Homeostasis of the lacrimal functional unit is needed to ensure a well-regulated ocular immune response comprising innate and adaptive phases. When the ocular immune system is excessively stimulated and/or immunoregulatory mechanisms are disrupted, the balance between innate and adaptive phases is dysregulated and chronic ocular surface inflammation can result, leading to chronic dry eye disease (DED). According to the Tear Film and Ocular Surface Society Dry Eye Workshop II definition, DED is a multifactorial disorder of the ocular surface characterized by impairment and loss of tear homeostasis (hyperosmolarity), ocular discomfort or pain, and neurosensory abnormalities. Dysregulated ocular immune responses result in ocular surface damage, which is a further contributing factor to DED pathology. Several therapeutics are available to break the vicious circle of DED and prevent chronic disease and progression, including immunosuppressive agents (steroids) and immunomodulators (cyclosporine and lifitegrast). Given the chronic inflammatory nature of DED, each of these agents is commonly used in clinical practice. In this study, we review the immunopathology of DED and the molecular and cellular actions of current topical DED therapeutics to inform clinical decision making.

Non-infectious uveitis (NIU) is an immune-mediated disease with clinical symptoms such as eye pain, redness, floaters, and light sensitivity. NIU is one of the leading causes of preventable blindness. This review describes current and emerging therapies for NIU. PubMed searches were conducted using the terms uveitis, therapy, corticosteroids, immunomodulators, biologics, intravitreal injections, intraocular implants, and adverse events deemed relevant if they presented data relating to prevalence, diagnosis, and treatment of uveitis. Diagnosis and management of NIU may require collaboration among different healthcare providers, including ophthalmologists and rheumatologists. Although many patients with NIU respond to corticosteroid (CS) therapy, long-term CS use can be associated with potentially severe adverse events. Localized CS therapies have been developed to reduce adverse events; however, some intravitreal injections and intraocular implants were linked to elevated intraocular pressure and cataracts. CS-sparing therapies such as biologics have demonstrated efficacy and safety while reducing CS burden. Biologics targeting tumor necrosis factor provide CS-sparing options for patients with NIU. Additional studies are needed to address long-term efficacy and safety of biologics targeting IL-6 and inhibitors of JAK/STAT. Biologics, JAK/STAT inhibitors, and improved localized therapies may provide additional options for patients with NIU.
