    Abstract Purpose: To present four cases of posterior ophthalmic manifestations associated with a temporal relationship to SARS-CoV-2 vaccination.
    Methods: Retrospective case series with a review of clinical findings.
    Results: Four patients presented with various posterior ophthalmic findings including uveitis, maculopathy, and optic neuropathy. Each of their clinical courses varied in terms of ophthalmic imaging and exam findings.
    Conclusion: The coronavirus disease 2019 (COVID-19) pandemic has ushered in a new wave of challenges to healthcare, epidemiological endeavors, and widespread vaccination efforts. Novel vaccines have been developed for the SARS-CoV-2 virus, including both mRNA and viral vector-based platforms. The ocular manifestations and side effects related to the SARS-CoV-2 vaccine is not well established or understood. There may be an association between vaccination and posterior ophthalmic manifestations.

    Abstract Purpose: To determine the rate, clinical features, and outcomes of filtering-associated endophthalmitis in eyes that underwent trabeculectomy or tube-shunt implantation.
    Design: Retrospective database study with selective chart review.
    Participants: Eyes that underwent incisional glaucoma surgery at our institution between January 1, 2012, and December 31, 2019.
    Methods: An electronic medical record database was used to identify all eyes that underwent trabeculectomy or tube-shunt implantation during the study period. Date of surgery, date of last ophthalmology clinic visit, and filtering-associated endophthalmitis diagnoses were obtained and used to perform a Kaplan-Meier analysis. The log-rank test was used to compare rates of filtering-associated endophthalmitis after trabeculectomy and tube-shunt implantation. Microbiology, management, and clinical outcomes data from patients with filtering-associated endophthalmitis were also collected and analyzed.
    Main outcome measures: Cumulative risk of filtering-associated endophthalmitis as determined by Kaplan-Meier analysis. Visual acuity improvement to within 2 lines of baseline at 3 months of follow-up and globe salvage at last available follow-up in eyes with filtering-associated endophthalmitis.
    Results: Kaplan-Meier analysis of 1582 eyes that underwent incisional glaucoma surgery yielded a 5-year cumulative incidence for filtering-associated endophthalmitis of 1.32%. No statistically significant differences were found between rate of endophthalmitis after trabeculectomy or tube-shunt implantation (P = 0.761, log-rank test). Seven of 16 cases (43.8%) of filtering-associated endophthalmitis showed positive culture results from either a vitreous sample or explanted tube shunt. Recovery of vision to within 2 lines of pre-endophthalmitis baseline was achieved in 53% of patients at 3 months of follow-up. Rate of globe salvage was 100% at last available follow-up.
    Conclusions: Risk of filtering-associated endophthalmitis is persistent and relatively constant for at least 5 years after incisional glaucoma surgery. The overall prognosis of filtering-associated endophthalmitis remains poor; however, good visual and anatomic outcomes can be achieved in some patients with prompt intervention.

    Abstract Purpose: This work reports a case of long-standing punctate inner choroidopathy (PIC) presenting with acute-onset multiple evanescent white dot syndrome.
    Methods: A 44 year-old man presented with new onset of flashes and a peripheral spot of blurry vision in the right eye. His ocular history included PIC in both eyes.
    Results: Corrected visual acuities and intraocular pressures were normal. Posterior segment examination of the right eye demonstrated old PIC lesions and new, deep-yellow lesions in the posterior pole and midperiphery. Four months later, these lesions had resolved.
    Conclusions: Coexistence of PIC and multiple evanescent white dot syndrome has been rarely reported, and more research is warranted to investigate a possible shared etiology.

    Abstract Purpose: To report a case of varicella zoster virus associated neuroretinitis confirmed via polymerase chain reaction analysis of ocular fluid.
    Observations: A 30-year-old man presented with a 1-week history of decreased vision in his left eye and ulcerative skin lesions above his left eyebrow. On exam, he had clinical findings consistent with neuroretinitis characterized by optic disc edema and formation of a macular star. Polymerase chain reaction analysis of aqueous fluid was positive for varicella zoster virus. He was treated with oral valacyclovir with excellent resolution of his symptoms and clinical findings.
    Conclusions and importance: Varicella zoster virus is a rare cause of neuroretinitis. We report for the first time a case of varicella zoster virus associated neuroretinitis confirmed by polymerase chain reaction analysis of ocular fluid. Molecular testing of ocular tissue may lead to a definitive diagnosis.

    Abstract Purpose of review: The intestinal microbiome is thought to play a role in the pathogenesis of inflammatory bowel disease (IBD). There are many shared clinical manifestations between IBD and spondyloarthritis (SpA), of which the most common are peripheral arthritis and uveitis. Clinical overlap along with similar genetics between these diseases suggests a possible shared pathogenetic mechanism, which might center on the intestinal microbiota. In this review, we discuss the available evidence that SpA is a microbiome-driven disease and indicate how SpA-associated uveitis could be tied to gut dysbiosis. We conclude by discussing different treatment paradigms targeting the intestinal microbiome for SpA.
    Recent findings: Recent studies support the growing evidence of the intestinal microbiome as a crucial player in SpA disease pathogenesis. There is emerging evidence that the gut microbiome may play a causative role in uveitis.
    Summary: The field is beginning to discover a new level of understanding how the intestinal microbiome is involved in SpA. Treatment methods to alter intestinal microbiota to treat SpA-related diseases are still in its infancy.

    Abstract Purpose: Idiopathic uveitis is frequently the most common diagnosis in series from uveitis clinics. This study sought to determine the percentage of patients initially diagnosed as idiopathic, noninfectious uveitis referred to a tertiary uveitis center who were subsequently found to have an identifiable cause of uveitis.
    Design: Retrospective case series.
    Methods: We performed a computerized database analysis of 179 consecutive patients who were referred to our practice with the diagnosis of idiopathic, noninfectious uveitis between 2008 and 2016. Patients were evaluated by a thorough history and ophthalmic examination with selected laboratory testing targeted by clues from the history and examination. Standardization of Uveitis Nomenclature (SUN) criteria were used to better assess different types of uveitis.
    Results: Fifty-two out of 179 (29.0%) patients initially diagnosed with idiopathic uveitis were subsequently diagnosed with an underlying condition. Among patients referred with a diagnosis of idiopathic disease, female patients were most commonly affected (121/179; 67.6%). Among subsequent diagnoses, sarcoidosis was the most common (19/52 or 36.5%), followed by HLA-B27-associated uveitis (11/52, 21.1%), infectious uveitis (6/52, 11.5%), tubulointerstitial nephritis with uveitis (6/52, 11.5%), and juvenile idiopathic uveitis (4/52, 7.7%). Other diagnosable conditions included Behçet disease, multifocal choroiditis, panuveitis, Crohn disease, multiple sclerosis, and relapsing polychondritis. An underlying condition was not found in 127 of 179 (70.9%) patients.
    Conclusions: We report that 29% of patients referred to our tertiary uveitis center diagnosed as "idiopathic" had an associated identifiable cause. Identifying an underlying condition associated with uveitis could be potentially lifesaving for some illnesses (eg, sarcoidosis with cardiac involvement) and is critical to management (eg, infection). Although we were able to use limited testing to classify many patients who had been previously incorrectly labeled with idiopathic uveitis, idiopathic uveitis remains the most common diagnosis in our uveitis clinic.

    Abstract Purpose: To report the clinical course of a patient with ocular manifestations of hyperviscosity syndrome associated with Waldenström macroglobulinemia, and for the first time, video imaging of mobile emboli in the conjunctival and retinal vasculature.
    Methods and patient: A 60-year-old woman with newly diagnosed Waldenström macroglobulinemia, with no visual complaints was evaluated by the Ophthalmology service for a baseline ocular examination.
    Results: At presentation, ocular examination revealed a visual acuity of 20/25 in each eye. Slit lamp examination showed mobile white emboli throughout the conjunctival vasculature of both eyes, which was captured on video. Dilated fundus examination revealed peripheral vascular occlusion along with extensive collateral formation in both eyes and as dilation of vessels at the posterior pole of the left eye. Mobile arterial and venous emboli were also observed in the retinal vasculature, which were captured with slit-lamp color and infrared reflectance video imaging.
    Conclusion: Hyperviscosity syndrome is a rare circulation sequelae that occurs when blood is thickened secondary to an increase in immunoglobulins or a hyperproliferation of blood components as in bone marrow dyscrasias. The increase in viscosity is plainly observable in the retinal circulation, and this syndrome is often diagnosed based on visual symptoms and fundus examination. We report a patient with Waldenström macroglobulinemia who presented with multiple ocular manifestations of hyperviscosity syndrome despite the absence of visual complaints. Ophthalmologists should be aware that regardless of the lack of any subjective visual changes, ocular findings of hyperviscosity syndrome should prompt quick referral to a Hematology Oncologist for evaluation of other end-organ damage. We also for the first time, provide video documentation of mobile emboli in the conjunctival and retinal vasculature.

    Abstract Background/purpose: To report two novel cases of intermediate uveitis associated with Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome.
    Methods: Observational case reports and review of the literature.
    Results: Both patients in this report had an established diagnosis of Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome before the onset of ocular inflammation. Infectious and noninfectious systemic conditions known to be associated with intermediate uveitis were excluded. Intermediate uveitis was confirmed clinically in both patients by the presence of vitritis, snowballs, and peripheral snowbanks in the region of the pars plana. Both cases had a course characterized by recurrent inflammation; in which systemic steroid treatment, and in one case, immunomodulatory therapy was necessary.
    Conclusion: Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome is an auto-inflammatory fever disorder in childhood. Although other auto-inflammatory disorders such as, Blau syndrome, Muckle-Wells syndrome, and Behcets disease have been associated with various forms of uveitis, Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis has never been reported to be associated with any type of ocular inflammation. We describe for the first time, two cases of Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome presenting with intermediate uveitis.

    Abstract Purpose: To review a case of bilateral diffuse chorioretinopathy as a presenting sign of juvenile dermatomyositis (JDM) and review the literature regarding retinal manifestations associated with this disease.
    Methods: Review of case record and literature regarding retinal manifestations related to juvenile dermatomyositis.
    Results: A 13-year-old girl presented with bilateral diffuse chorioretinopathy as the presenting sign of juvenile dermatomyositis. A review of the literature suggests that retinopathy associated with JDM is a rare finding that is symptomatic to patients and often responds to systemic treatment of juvenile dermatomyositis. This is also the first documented case of paracentral acute middle maculopathy in the setting of juvenile dermatomyositis.
    Conclusion: Chorioretinopathy is a rare finding in juvenile dermatomyositis. While all patients with JDM likely do not warrant screening ophthalmologic examinations, any patient who has visual symptoms should have a careful dilated examination to evaluate for retinopathy or steroid-induced cataracts.
