Abstract
INTRODUCTION We aimed to analyze the thicknesses of the retinal sublayer and peripapillary retinal nerve fiber layer (pRNFL) in patients with juvenile systemic lupus erythematosus (JSLE) without lupus retinopathy. METHODS Thirty-six patients with JSLE (36 eyes) and 30 control subjects (30 eyes) were included retrospectively. Demographic data, disease duration, and clinical manifestations were recorded. Optical coherence tomography was used to examine the macula and optic disc. The thicknesses of the retina, ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), retinal pigment epithelium (RPE), and pRNFL were measured. The correlation between the thickness of retina and disease duration, erythrocyte sedimentation rate (ESR) were investigated. RESULTS The retinal thicknesses of I3 and T3 were thinner in the JSLE group than in the control group (P = 0.019, P = 0.043, respectively). The thicknesses of the I3 and S6 sectors of the GCL decreased significantly (P = 0.013, and P = 0.022, respectively). The thickness of the S6 sector of the IPL was reduced in the JSLE group compared with the control group (P = 0.047). The JSLE group showed significant decrease in the thickness of the central sector of the ONL (P = 0.034). No statistically significant differences in INL, OPL, RPE, and pRNFL thicknesses were found. The retinal thicknesses of I3 (r = -0.386, P = 0.020) and T3 (r = -0.384, P = 0.021) presented negative associations with ESR, but had no significant correlations with disease duration. CONCLUSIONS Retinal thinning was observed in patients with JSLE without lupus retinopathy, and this change was more pronounced in the inner layer. Key Points • Retinal thinning occurs in JSLE patients without lupus retinopathy. • Changes in retinal thicknesses are related to the ESR.

Comparison of the quantitative values of peripapillary, macular and choriocapillary microvascular structures according to the presence of lupus nephritis in patients with systemic lupus erythematosus. Photodiagnosis Photodyn Ther 2024; 48:104263. [PMID: 38955255 DOI: 10.1016/j.pdpdt.2024.104263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 06/26/2024] [Accepted: 06/28/2024] [Indexed: 07/04/2024]
Abstract
PURPOSE To determine whether there are quantitative changes in macular, choriocapillary, and peripapillary microvascular structures using optical coherence tomography angiography (OCTA) due to the presence of lupus nephritis (LN) in patients with systemic lupus erythematosus (SLE) and to investigate the correlation between these quantitative values and disease duration. METHODS Fifty -five patients followed up in the rheumatology clinic with an SLE diagnosis were evaluated. As the control group, 61 eyes of 61 age- and gender-matched healthy individuals were included. The patients with SLE were further divided into two groups: those with LN (29 eyes) and those without LN (26 eyes). Macular, choriocapillary, and peripapillary microvascular structures were quantitatively analyzed with OCTA and compared between the three study groups. A correlation analysis of the measured quantitative values and disease duration was also performed. RESULTS In macular microvascular (MMV) analysis, the vessel densities (VDs) of the superficial capillary plexus (SCP) decreased in both SLE groups, while those of the deep capillary plexus (DCP) decreased only in the SLE group with LN. The foveal density significantly decreased in the SLE group with LN compared to the control group, there were no significant differences in terms of the radial peripapillary capillary VDs or the choriocapillaris flow area. Disease duration was not correlated with any of the quantitative parameters measured by OCTA in either SLE group. CONCLUSIONS Identifying differences in retinal microvascular circulation in SLE patients with kidney damage helps predict possible nephropathy and therefore may guide the treatment process of the patient.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that affects multiple organs and systems. Ocular involvement is estimated to manifest in one-third of individuals with SLE, of which lupus retinopathy and choroidopathy represent the severe subtype accompanied by vision impairment. Advancements in multimodal ophthalmic imaging have allowed ophthalmologists to reveal subclinical microvascular and structural changes in fundus of patients with SLE without ocular manifestations. Both ocular manifestations and subclinical fundus damage have been shown to correlate with SLE disease activity and, in some patients, even precede other systemic injuries as the first presentation of SLE. Moreover, ocular fundus might serve as a window into the state of systemic vasculitis in patients with SLE. Given the similarities of the anatomy, physiological and pathological processes shared among ocular fundus, and other vital organ damage in SLE, such as kidney and brain, it is assumed that ocular fundus involvement has implications in the diagnosis and evaluation of other systemic impairments. Therefore, evaluating the fundus characteristics of patients with SLE not only contributes to the early diagnosis and intervention of potential vision damage, but also holds considerate significance for the evaluation of SLE vasculitis state and prediction of other systemic injuries.

Abstract
Systemic Lupus Erythematosus (SLE) is a complex autoimmune disorder characterized by immune dysregulation and multi-organ involvement. In this concise brief review, we highlight key insights into Ocular Systemic Lupus Erythematosus (SLE), an intricate autoimmune disorder with diverse organ involvement. Emphasizing the formation of autoantibodies and immune complex deposition, we delve into the inflammation and damage affecting ocular structures. Clinical presentations, ranging from mild dry eye syndrome to severe conditions like retinal vasculitis, necessitate a comprehensive diagnostic approach, including clinical exams, serological testing, and imaging studies. Differential diagnosis involves distinguishing SLE-related ocular manifestations from other autoimmune and non-inflammatory ocular conditions. The multidisciplinary management approach, involving rheumatologists, ophthalmologists, and immunologists, tailors treatment based on ocular involvement severity, encompassing corticosteroids, immunosuppressive agents, and biologics. Follow-up is crucial for monitoring disease progression and treatment response. Future perspectives revolve around advancing molecular understanding, refining diagnostic tools, and exploring targeted therapies. Novel research areas include genetic factors, microbiome composition, and biotechnology for tailored and effective SLE ocular treatments.

Abstract
OBJECTIVE The aim is to evaluate subclinical alterations of macular microvasculature in patients with juvenile systemic lupus erythematosus (JSLE). METHODS This is a cross-sectional study of 29 eyes of 29 patients diagnosed with JSLE and 29 eyes of 29 healthy controls. The vessel density (VD) of the superficial capillary plexus (SCP), intermediate capillary plexus (ICP), deep capillary plexus (DCP), choriocapillaris (CC), and area of foveal avascular zone (FAZ) was measured using optical coherence tomography angiography (OCTA). A multiple linear regression analysis was performed to evaluate the effects of disease duration and activity on OCTA parameters. RESULTS The VD of total (p = .007) and the superior (p = .014) and inferior (p = .004) quadrants in SCP was significantly lower in children with JSLE. The VD of total and all quadrants in ICP decreased (p = .015, p = .0045, p = .015, p = .033), except that of the temporal quadrant (p = .366). The total (p = .011) and superior quadrant (p<.01) DCP-VD showed a significant decrease in children with JSLE. The decrease in VD in the total (p = .003) and nasal quadrant (p = .017) of CC was also remarkable. No significant difference in the FAZ area was found between the two groups (p = .774). Multiple linear regression analyses adjusted for age, spherical equivalent, and intraocular pressure were conducted. No contributing factor to OCTA parameters was found. CONCLUSIONS We demonstrated decreased VD in all layers of the retina and CC in patients with JSLE without ocular involvement. Early screening and close follow-up were recommended.

Abstract
Systemic lupus erythematosus (SLE) is a chronic, systemic, autoimmune connective tissue disease that affects several vascular territories. We sought to assess the role of optical coherence tomography angiography in detecting subclinical microvascular alterations in SLE patients. PubMed, Scopus, and Web of Science databases were systematically searched until January 21, 2023. Studies using optical coherence tomography angiography as a primary diagnostic method to evaluate the macular microvasculature of SLE patients versus healthy controls were included. Primary outcomes were macular vessel density and foveal zone parameters. A meta-analysis was performed using a random-effects model. Of 301 screened abstracts, 15 were found eligible, enrolling 1,246 eyes from 1,013 patients. SLE patients presented a reduction of macular vessel density at both plexuses in all zones (whole scan, fovea, parafovea, and perifovea), and of foveal density compared with healthy controls. No differences were found at foveal avascular zone parameters. SLE patients presented a reduction of macular vessel density without signs or symptoms of SLE ocular involvement. Optical coherence tomography angiography application for the assessment of subclinical microvascular changes needs to be elucidated with longitudinal studies.

Abstract
OBJECTIVE The aim of the present study was to detect preclinical changes in SLE patients in retinal microvascularization or retinal and optical nerve structure by optical coherence tomography. METHODS This cross-sectional, single-centre study aimed to describe structural changes [macular and retinal nerve fibre layer (RNFL) thickness] by structural spectral-domain optical coherence tomography (SD-OCT) and perifoveal vascular [vessel density (VD) and vascular perfusion (VP) and foveal avascular zone (FAZ) structural parameters] findings by OCT angiography (OCTA) in 78 SLE patients and 80 healthy volunteers. In addition, we analysed their association with clinical and laboratory parameters, medications received, disease duration, and SLE activity and damage. RESULTS Structural parameters by SD-OCT and perifoveal vascular parameters by OCTA were decreased in SLE patients compared with controls. OCTA parameters (VD, VP and FAZ circularity) and macular thickness were also decreased in patients with longer disease duration (>10 years). The presence of aPLs was associated with a decreased RNFL thickness, mainly in the inferior quadrants. Patients developing APS also showed decreased RNFL thickness and OCTA flow changes. SD-OCT and OCTA results were not associated with disease activity. Foveal structural parameters were lower in patients with higher damage score. CONCLUSION SD-OCT and OCTA can detect preclinical structural and microcirculatory changes in SLE patients. Structural and perifoveal vascular macular changes in SLE patients are related to disease duration. Macular structural parameters were impaired in patients with higher disease damage. APS seems to be associated with preclinical damage to the optic nerve and impairment of the perifoveal microvasculature.

Abstract
Introduction The aim was to detect subclinical structural retinal abnormalities in optical coherence tomography (OCT) in ophthalmologically asymptomatic systemic lupus erythematosus (SLE) patients without signs of lupus retinopathy or drug toxicity in fundus examination and in OCT and to assess the relationship between OCT parameters and disease activity, therapy type and burden on other organs to demonstrate the utility of OCT in early retinal impairment in SLE patients. Material and methods Cross-sectional study. Thirty-three SLE patients (57 eyes) and 31 healthy individuals (56 eyes) were enrolled in the study. We excluded patients with evidence of lupus retinopathy or hydroxychloroquine (HCQ) toxicity on OCT or fundus examination to reveal any subclinical changes. All patients underwent full ophthalmologic examination in the slit lamp including best corrected visual acuity, tonometry, and OCT. The Kolmogorov-Smirnov distribution test was used to assess the normal distribution in quantitative values. The differences between the individual measured parameters in the groups were analyzed using the Mann-Whitney U test. Spearman's rank correlation test was used to assess the correlation between the measured parameters and quantitative clinical data. Results There was no difference in the OCT findings between SLE and healthy control groups. Among the study group a negative correlation was found between disease duration and age and retinal nerve fiber layer thickness in the inferior quadrant (p = 0.0063, p = 0.0036). No correlations were observed between examined retinal parameters and duration of hydroxychloroquine therapy, hydroxychloroquine as well as chloroquine cumulative dose and disease activity indices. Conclusions Optical coherence tomography is a widespread ophthalmic modality used for SLE retinopathy and HCQ toxicity screening. Our study did not demonstrate its clinical potency in diagnosis of subclinical retinal involvement. An optical coherence tomography device seems to be less sensitive in subclinical retinal impairment detection than optical coherence tomography angiography.

Abstract
Objective This study aimed to investigate subclinical retinal microvascular changes with optical coherence tomography angiography (OCTA) in patients with systemic lupus erythematosus (SLE) and healthy controls (HCs), and to evaluate the relationship between OCTA findings and Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). Materials and Methods In this study, 47 eyes of SLE and 41 eyes of healthy control (HC) were evaluated. The SLE patients were divided into two subgroups: low disease activity (LDA) (SLEDAI≤5) and high disease activity (HDA) (SLEDAI>6). The results of OCTA were compared between SLE patients and HCs as well as the SLE subgroups. The relationship between OCTA results and SLEDAI-2K was evaluated. Results There were no differences in foveal avascular zone (FAZ) areas between the SLE patients and HCs. Central foveal thickness (CFT) was lower in SLE patients ( p = .046). Superficial capillary plexus (SCP) vessel density (VD) in SLE patients was significantly lower only in the foveal area compared to that in HCs ( p = .006). Deep capillary plexus (DCP) VD in SLE patients was significantly lower in all areas except the temporal parafoveal area compared to that in the HCs. There was no statistically significant difference between SLE groups with LDA and HDA in FAZ or any of the other areas, including SCP and DCP. When the correlation between OCTA findings and SLEDAI-2K was examined, both SCP and DCP VD were found to be negatively correlated. conclusions It was observed that DCP VDs were affected in SLE patients with LDA, and SCP VDs were also affected in addition to DCP with HDA. This suggests that DCP may be the first capillary plexus to be comprised in SLE. VDs were negatively correlated with disease activity. It was concluded that OCTA can be a useful tool in assessing subclinical retinal microvascular pathology and disease activity in patients with SLE.

Abstract
PURPOSE Retinal manifestations are present in 10% of patients with systemic lupus erythematosus (SLE) and consist of vascular changes that can be sight-threatening. Optical coherence tomography angiography (OCTA) is a novel imaging modality that detects movement inside the blood vessels without dye injection and transforms this movement into an angiographic map. The aim of this study is to describe subclinical vessels changes in the eyes of patients with SLE but no retinal manifestations. METHODS In this cross-sectional study, 15 patients with SLE but no clinical ophthalmic manifestations were scanned through OCTA of the iris and at the level of the macula. Qualitative aspects of the iris vessels, and measure of the foveal avascular zone (FAZ) and vessel density were compared to a cohort of 15 normal controls. RESULTS Patients with SLE, even in the absence of ophthalmic manifestations, present a qualitative increase in the iris vessels flow, and enlargement of the FAZ (0.22 ± 0.12 mm2) and a decrease in the vascular density (11.221 ± 1.933 mm-1) of the superficial capillary plexus on OCTA that cannot be highlighted clinically. DISCUSSION OCTA can be used in a noninvasive way to detect subclinical vascular changes in patients with SLE. How this information will influence the follow-up and management of these cases will require further prospective studies with a collaborative effort between ophthalmologists and rheumatologists.
