Background: Monoclonal gammopathy of undetermined significance (MGUS) is a plasma cell dyscrasia and precursor to multiple myeloma. It has known ocular manifestations, but has not previously been shown to have an association with autoimmune retinopathy.
Case Presentation: A 57 year-old female presented with 1 year of progressive, bilateral, peripheral vision loss, photopsias, and nyctalopia. Her fundus examination and extensive ancillary testing were concerning for hereditary versus autoimmune retinopathy. The patient was found to have anti-retinal antibodies against carbonic anhydrase II and enolase proteins with a negative genetic retinal dystrophy panel. Malignancy work-up was negative, but the patient was diagnosed with MGUS, a premalignant condition. The patient was treated with immunosuppressive therapies, with rituximab demonstrating the most robust therapeutic response with respect to patient symptoms and ophthalmic testing.
Conclusions: MGUS should be considered as a potential etiology of autoimmune retinopathy in patients without other autoimmune or malignant disease processes. Immunosuppressive therapy may be helpful in limiting disease progression, with rituximab showing efficacy in retinopathy refractory to other agents.

Purpose: Polymorphism and mutations of human leukocyte antigens (HLAs) and calreticulin are risk factors for uveitis. Here, we sought to determine the therapeutic effects of Clarstatin, a cyclic peptide antagonist of the HLA shared-epitope-calreticulin interaction, in experimental autoimmune uveitis (EAU) models.
Methods: Mice were injected with Clarstatin intraperitoneally and its effect was compared to that of corticosteroid.

Previous observational studies have reported inconsistent associations between air pollution and autoimmune eye diseases (AEDs). The primary objective of this Mendelian randomization (MR) study was to investigate the causal link of air pollution with AEDs risk. The instrumental variables were selected based on genome-wide association study data.

To investigate for the risk of uveitis among such patients. A retrospective cohort study utilized the TriNetX database and recruited pediatric autoimmune patients diagnosed between January 1st 2004 and December 31st 2022. The non-autoimmune cohort were randomly selected control patients matched by sex, age, and index year.

Background: Lupus podocytopathy (LP) is a non-immune complex-mediated glomerular lesion in systemic lupus erythematosus (SLE), characterized by the diffuse effacement of podocyte processes without immune complex deposition or with only mesangial immune complex deposition. LP is a rare cause of nephrotic syndrome in SLE patients with implications for prognosis and treatment.
Case Report: We present the case of a 28-year-old woman with a medical history of type 1 diabetes mellitus (T1DM) who presented with lower limb edema, dyspnea, hypercholesterolemia, with nephrotic range proteinuria, without acute kidney injury, and laboratory findings compatible with auto-immune hemolytic anemia.
Paraneoplastic retinopathy (PR) is a rare autoimmune condition typically associated with progressive visual loss and is often linked to anti-recoverin antibodies. Paraneoplastic optic neuropathy (PON) is classically associated with collapsin response-mediator protein (CRMP-5). We present a unique case of non-progressive CRMP-5-associated perifoveal retinitis in a 79-year-old female with a history of breast carcinoma, who has maintained a stable visual acuity over an extended follow-up period of three years.
