Ocular Immunology and Inflammation Jun 2024To report a challenging case of serologically confirmed posterior uveitis due to leptospirosis.
PURPOSE
To report a challenging case of serologically confirmed posterior uveitis due to leptospirosis.
METHODS
Review of medical records.
RESULTS
Thirteen-year-old boy presented focal necrotizing retinochoroiditis after flood exposure. Laboratory work-up confirmed leptospirosis infection and proper antibiotic treatment was done. The patient evolved well. but during late follow-up he developed nummular keratitis.
CONCLUSION
Leptospirosis is a possible etiology of necrotizing posterior uveitis. The use of antimicrobial therapy is controversial but was used in this case, in association with corticosteroids, leading to resolution of retinal inflammation. Despite treatment, the patient developed late corneal opacities, which did not lead to visual impairment.

PURPOSE
Explore the visual outcome and complications of iris fixation intraocular lenses (IFIOL) and sutureless scleral-fixated intraocular lenses (SSFIOL) in the surgical management of patients without exchanging dislocated posterior chamber intraocular lenses (PCIOLs) in the vitreous.
METHODS
Retrospectively, 14 IFIOL and 15 SSFIOL reimplantations for dislocated PCIOLs were analyzed. Mean follow-up of reIFIOL group and reSSFIOL group: 11.3±2.0 (range: 9-15) months and 11.8±2.2 (range: 9-16) months, respectively. Preoperative and postoperative outcomes, operative indications, and complications were evaluated.
RESULTS
Primary surgical indications were pseudoexfoliation (PXE) (21.4%), post-cataract surgery (PCS) (35.7%), trauma (42.8%) in the reIFIOL group, and PXE (26.6%), PCS (40%) trauma (33.3%) in reSSFIOL group, respectively. At the latest follow-up, there was an improvement in best-corrected visual acuity (BCVA) (0.053±0.051 to 0.53±0.13, P<0.0001) in reIFIOL group and (0.05±0.02 to 0.64±0.16, P<0.0001) in reSSFIOL group. Postoperative complications of reIFIOL group and reSSFIOL group included corneal edema (14.2%; nil), IOP elevation (21.4%; 7.1%), bullous keratopathy (14.2%; nil), anterior uveitis (35.7%; 13.3%), cystoid macular edema (CME) (21.4%; 7.1%), pupil ovalization (21.4%; nil), broken haptic (none; 13.3%), IOL exchange (nil; 13.3%), and vitreous hemorrhage (nil; 14.2%).
CONCLUSIONS
Self-dislocated IOL reimplantation may enable much earlier visual rehabilitation in the reSSFIOL group than in the reIFIOL group. Moreover, the 27G trocar-assisted reSSFIOL technique takes a shorter operation time and relatively lower complication rates. However, further prospective studies with larger series and longer follow-up periods are required.

PURPOSE
Uveitis is a common ocular manifestation in individuals with sarcoidosis, a multisystem inflammatory disorder. This study aimed to explore clinical and genetic factors associated with the presence or absence of uveitis in sarcoidosis patients.
METHODS
Total 625 Dutch sarcoidosis patients were included. Among these, 170 underwent ophthalmic examination, and 61 were diagnosed with uveitis. Demographic and clinical data, including age, gender, race, biopsy status, chest radiography findings, TNF-α inhibitor treatment, and uveitis classification were collected retrospectively from medical records. Genetic data was available for HLA haplotypes, G-308A, and G16071A polymorphisms.
RESULTS
The majority of the patients presented with bilateral uveitis (80.3%). The proportion of women was higher in the uveitis group compared to the non-uveitis group (67.2% and 47.7%; = 0.014). Pulmonary involvement (chest radiographic stage II-III) was significantly lower in patients with uveitis (36.1% versus 64.2%; < 0.001). Patients with uveitis were more often treated with TNF-α inhibitors (67.2% versus 29.4%; < 0.001) and the outcome was better compared with the non-uveitis group, 92% vs 68%, responders ( < 0.012). Uveitis patients treated with TNF-α inhibitors (either adalimumab or infliximab) were more likely to suffer from intermediate or posterior uveitis than anterior uveitis. Genetic analysis identified a significant association between the G16071A GG genotype and uveitis ( = 0.012).
CONCLUSION
This study highlights distinctive demographic, clinical and genetic features associated with uveitis in sarcoidosis patients. Ocular sarcoidosis was more prevalent in women. Further research is warranted to explore the implications of these findings for treatment strategies and prognostic assessments.

A 35-year-old gentleman came to the ophthalmology outpatient department with complaints of bilateral ocular pain, redness and photophobia since three weeks with similar prior history. The patient was a diagnosed case of systemic sarcoidosis since two years with pulmonary, dermatological and neurological involvement for which he was already on treatment which included oral immunosuppressants, steroids, anticonvulsants and multivitamins. On examination, the best corrected visual acuity was 6/18 in the right eye and 6/12 in the left eye. On slit lamp and fundus examination, the patient showed signs of anterior and posterior uveitis in both eyes, the right eye more than the left eye. Treatment was initiated with topical corticosteroids and beta blockers and the patient improved following medical management.

A 12-year-old boy with underlying severeand poorly controlled atopic dermatitis (AD) associated with atopic conjunctivitis and rhinitis presented with a right painless blurring of vision for two weeks. On examination, his right eye visual acuity was 1/60,with grade 1 relative afferent pupillary defect (RAPD). Anterior segment examination revealed anterior uveitis with dense posterior subcapsular cataract and hazy fundus view. B-scan ultrasound suggested a shallow total retinal detachment. Intraoperatively, a large retinal dialysis was found. This paper highlights the need for a high index of suspicion of retinal dialysis in a child with underlying AD and the importance of good control of this systemic condition to prevent ocular morbidity.

Even in the post-coronavirus disease 2019 (COVID-19) era, it is prudent to exercise caution regarding the timing between intravitreal anti-vascular endothelial growth factor (VEGF) injections and COVID-19 vaccinations, as ocular inflammation can occur following both procedures. However, this perspective has not been sufficiently discussed thus far. Herein, we report a case of acute noninfectious anterior ocular inflammation following an intravitreal injection of ranibizumab biosimilar (RBZ BS, Senju Pharmaceuticals, Japan) in a patient recently vaccinated against COVID-19. A 74-year-old male with myopic choroidal neovascularization (CNV) in the left eye was treated with RBZ BS intravitreal injection. He received his fourth COVID-19 vaccination with messenger ribonucleic acid (mRNA)-1273 (Moderna) two days prior to his second RBZ BS intravitreal injection. He reported no systemic symptoms associated with the fourth COVID-19 vaccination. The second RBZ BS intravitreal injection was safely performed without complications. However, a few hours later, he experienced blurred vision without ocular pain in his left eye, a symptom not observed after the first injection. He visited a local ophthalmologic clinic the following day and was subsequently referred to our hospital due to anterior ocular inflammation in the left eye. His vision in the left eye was 0.3 decimal best-corrected visual acuity. Examination revealed non-granulomatous anterior ocular inflammation with 3+ cells and 2+ flare in the left eye. Anterior vitreous inflammation, keratic precipitates, or conjunctivitis was absent. Fundus examination also showed no signs of posterior inflammation. Both fluorescence angiography and indocyanine green angiography revealed staining corresponding to CNV without retinal vasculature leakage. There is nothing abnormal with the right eye based on the examination. Given that the noninfectious ocular inflammation was likely, based on the acute onset of symptoms within less than 24 hours following the RBZ BS intravitreal injection, and the presence of non-granulomatous inflammation only in the anterior segment without ocular pain, betamethasone eye drops four times daily was initiated in the left eye on the first day following the second RBZ BS intravitreal injection. Then, his ocular inflammation improved to mild by the fourth day post-injection. His eye eventually cleared, with no cells or flare in the anterior chamber at five months. Eventually, given the clinical course of good response to only topical steroid therapy, the diagnosis of noninfectious anterior ocular inflammation following RBZ BS in the case of a recent episode of COVID-19 vaccination was retrospectively confirmed. Although this case represents one of the initial instances of noninfectious ocular inflammation following RBZ BS (Senju Pharmaceuticals) administration, sterile ocular inflammation after other intravitreal anti-VEGF therapy has already been well-reported. In addition, given the recent COVID-19 vaccination, the ocular inflammation might be influenced by the vaccination, synergistically leading to vaccine-associated uveitis with similar signs and symptoms. In conclusion, to prevent such a complex situation, it is advisable to consider an adequate interval between COVID-19 vaccination and intravitreal anti-VEGF injections.

INTRODUCTION
The aim of this study was to investigate if a negative test result for L265P mutation, associated with vitreoretinal lymphoma (VRL) and primary CNS lymphoma, in liquid biopsies from intraocular fluids can be a useful adjuvant test to diagnose chronic lymphocytic leukemia in clinically challenging cases.
CASE PRESENTATIONS
We selected patients with a past medical history or examinations findings suspicious for intraocular lymphoma. We evaluated both vitreous and aqueous humor-derived (AHD) L265P mutation from patients that had suspected intraocular lymphoma that warranted a liquid biopsy procedure. Gold-standard cytopathology, flow cytometry, and gene rearrangement studies were also performed. All 4 patients had negative AHD L265P mutation testing. Gold-standard testing (cytology) either showed paucicellular specimens (1/4) or specimens with high background inflammation (3/4). One case showed a rare B-cell clonal population (CD5, Kappa-restricted by flow cytometry), but this was not sufficient to make any definitive diagnosis. All patients were subsequently initiated on systemic therapy and had improvement in their disease burden.
CONCLUSIONS
Negative AHD L265P mutation testing can serve as an adjuvant molecular test to diagnose difficult cases of intraocular CLL.

PURPOSE
Putative microglia were recently detected using adaptive optics ophthalmoscopy in healthy eyes. Here we evaluate the use of nonconfocal adaptive optics scanning light ophthalmoscopy (AOSLO) for quantifying the morphology and motility of presumed microglia and other immune cells in eyes with retinal inflammation from uveitis and healthy eyes.
DESIGN
Observational exploratory study.
PARTICIPANTS
Twelve participants were imaged, including 8 healthy participants and 4 posterior uveitis patients recruited from the clinic of 1 of the authors (M.H.E.).
METHODS
The Pittsburgh AOSLO imaging system was used with a custom-designed 7-fiber optical fiber bundle for simultaneous confocal and nonconfocal multioffset detection. The inner retina was imaged at several locations at multiple timepoints in healthy participants and uveitis patients to generate time-lapse images.
MAIN OUTCOME MEASURES
Microglia and macrophages were manually segmented from nonconfocal AOSLO images, and their morphological characteristics quantified (including soma size, diameter, and circularity). Cell soma motion was quantified across time for periods of up to 30 minutes and their speeds were calculated by measuring their displacement over time.
RESULTS
A spectrum of cell morphologies was detected in healthy eyes from circular amoeboid cells to elongated cells with visible processes, resembling activated and ramified microglia, respectively. Average soma diameter was 16.1 ± 0.9 μm. Cell movement was slow in healthy eyes (0.02 μm/sec on average), but macrophage-like cells moved rapidly in some uveitis patients (up to 3 μm/sec). In an eye with infectious uveitis, many macrophage-like cells were detected; during treatment their quantity and motility decreased as vision improved.
CONCLUSIONS
In vivo adaptive optics ophthalmoscopy offers promise as a potentially powerful tool for detecting and monitoring inflammation and response to treatment at a cellular level in the living eye.

PURPOSE
This cross-sectional optical coherence tomography angiography (OCTA) study aimed to assess the macular and optic nerve head (ONH) vascular density, foveal avascular zone, and outer retina and choriocapillaris flow in oligoarticular juvenile idiopathic arthritis (oJIA).
STUDY DESIGN
Prospective.
METHODS
Twenty-two eyes of 22 oJIA patients with uveitis (oJIA-U), 20 eyes of 20 oJIA patients without uveitis (isolated oJIA), and 26 healthy volunteers of similar ages and sexes were investigated. The superficial capillary plexus (SCP) and deep capillary plexus (DCP), ONH, foveal avascular zone (FAZ) parameters, the flow area of the outer retina, and choriocapillaris were evaluated.
RESULTS
Compared with the control group, both the oJIA-U group and isolated oJIA group showed significantly decreased vessel density of parafovea (p = 0.031 and p = 0.047, respectively) in DCP. Choriocapillaris flow area at 1 mm radius was significantly lower in the oJIA-U group compared to the control group (p = 0.001). Choriocapillaris flow area at 2- and 3-mm radius were significantly lower in the oJIA-U group compared to the control group (p < 0.001, for both) and isolated oJIA-U group compared to the control group (p = 0.008 and p = 0.001, respectively). The VD and thickness parameters of SCP and ONH, FAZ, and outer retina flow area were similar between the groups.
CONCLUSIONS
oJIA patients with and without uveitis revealed a decreased vessel density in the deep parafoveal region and choriocapillaris flow. Our findings suggest that retinal choroidal microvascular changes could be evident in oJIA-U patients without posterior segment involvement as well as oJIA patients without uveitis.

Comparative Study
BACKGROUND
Vitreoretinal lymphoma (VRL) is a rare intraocular malignancy that poses a diagnostic challenge due to the non-specific clinical presentation that resembles uveitis. The use of spectral domain optical coherence tomography (SD-OCT) has emerged as a valuable imaging tool to characterize VRL. Therefore, we sought to determine the specific OCT features in VRL compared to the uveitides.
METHODS
Retrospective chart review of patients who were seen at Mayo Clinic from January 1, 2010 through December 31, 2022. The medical records and SD-OCT images at time of initial presentation were reviewed in patients with biopsy-proven VRL, intermediate uveitis, or biopsy-confirmed sarcoid posterior uveitis. Patients with VRL or similar uveitides including intermediate uveitis or sarcoid posterior uveitis were included.
RESULTS
There were 95 eyes of 56 patients in the VRL group and 86 eyes of 45 patients in the uveitis group, of whom 15 (33.3%) were diagnosed with intermediate uveitis and 30 (66.7%) with sarcoid chorioretinitis. The SD-OCT features more commonly seen at initial presentation in VRL patients (vs. uveitis) included preretinal deposits (31.6% vs. 9.3%, p = 0.002), intraretinal infiltrates (34% vs. 3.5%, p < 0.001), inner retinal hyperreflective spots (15.8% vs. 0%, p < 0.001), outer retinal atrophy (22.1% vs. 2.3%, p < 0.001), subretinal focal deposits (21.1% vs. 4.7%, p = 0.001), retinal pigmented epithelium (RPE) changes (49.5% vs. 3.5%, p < 0.001), and sub-RPE deposits (34.7% vs. 0%, p < 0.001). Features more frequently seen in uveitis included epiretinal membrane (ERM) (82.6% vs. 44.2%, p < 0.001), central macular thickening (95.3% vs. 51.6%, p < 0.001), cystoid macular edema (36% vs. 11.7%, p < 0.001), subretinal fluid (16.3% vs 6.4%, p = 0.04), and subfoveal fluid (16.3% vs. 3.2%, p = 0.003). Multivariate regression analysis controlling for age and sex showed absence of ERM (OR 0.14 [0.04,0.41], p < 0.001) and absence of central macular thickening (OR 0.03 [0,0.15], p = 0.02) were associated with VRL as opposed to uveitis.
CONCLUSION
OCT features most predictive of VRL (vs. uveitis) included absence of ERM and central macular thickening.
