Ocular fundus changes and association with systemic conditions in systemic lupus erythematosus

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.

Clinical features of ocular damage in systemic lupus erythematosus and risk factors for hydroxychloroquine-related complications

Ocular damage in systemic lupus erythematosus (SLE) may cause insidious visual impairment, but its clinical features and the risk of hydroxychloroquine (HCQ)-related complications are still controversial. We performed a meta-analysis to evaluate ocular damage in SLE, the correlation between eye and systemic involvement, and the ocular side effects of treatment. The database PubMed, Embase, and Ovid were used for literature from reception to July, 2023, and the calculation was carried out with R. About 48,693 patients from 66 studies were included. The results indicated that ocular damage in SLE was insidious, appearing in 28 % of patients with no complaints. The most common symptoms and manifestations were dry eye (30 %) and keratoconjunctivitis sicca (26 %). Retinopathy was detected in 10 % of patients and was related to antiphospholipid antibodies (25 % versus 8 %). The proportion of retinopathy also significantly increased in patients with lupus nephropathy or neuropsychiatric systemic lupus erythematosus (risk ratio of 2.29 and 1.95, respectively). HCQ was used in 82 % of patients, of which 4 % suffered from ocular toxicity. HCQ-related retinopathy was dose-dependent. Dosage below 5 mg/kg/d was relatively effective and safe for long-term use, while routine examination was recommended.

Unveiling Ocular Manifestations in Systemic Lupus Erythematosus

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.

Scleral changes in systemic lupus erythematosus patients using swept source optical coherence tomography

Purpose

This study aims to examine scleral thickness in patients with systemic lupus erythematosus (SLE) without clinically evident scleritis and episcleritis, utilizing swept-source optical coherence tomography (SS-OCT).

Methods

This cross-sectional single center study compared scleral thickness (Nasal scleral thickness 1mm, 2mm, 3mm, 6mm from scleral spur; Temporal scleral thickness 1mm, 2mm, 3mm, 6mm from scleral spur) in 73 SLE patients without clinically evident scleritis and episcleritis and 48 healthy volunteers with SS-OCT. Further, we investigated the correlation between scleral thickness in SLE patients and various parameters including laboratory markers, disease duration, disease activity, and organ involvement.

Results

Across all measured sites (nasal scleral thickness at distances of 1mm, 2mm, 3mm, and 6mm from the scleral spur, and temporal scleral thickness at the same distances), the scleral thickness in the SLE group was significantly greater than that in the control group (all p-values <0.001). SLE patients with a disease duration of 5 years or less exhibited a higher scleral thickness compared to those with a more prolonged disease duration. Patients with a higher erythrocyte sedimentation rate (ESR) had a thinner temporal scleral thickness. However, no significant associations were identified between scleral thickness and disease activity, organ involvement, or other laboratory markers.

Conclusion

Scleral thickness measured by SS-OCT was higher in SLE patients than healthy controls. Changes in scleral thickness in SLE patients are related to disease duration and ESR. SS-OCT can detect asymptomatic structural changes in SLE patients and may be a useful tool in the evaluation of early scleral abnormality.

Risks of posterior segment ocular ischaemic events in patients with systemic lupus erythematosus: a population-based cohort study in Taiwan

BACKGROUD/AIM

Ocular involvement in systemic lupus erythematosus (SLE) is often primarily recognised by ophthalmologists rather than internists. This study aims to investigate the incidence and risk factors for the occurrence of posterior ocular ischaemic events (OIE), including retinal vein occlusion (RVO), retinal artery occlusion (RAO) and ischaemic optic neuropathy (ION), in patients with SLE.

METHODS

A national database in Taiwan was used to identify 24 472 patients newly diagnosed with SLE and 244 720 age-matched and sex-matched controls between 1997 and 2012. New occurrences of OIE and confounding factors were recorded. The Kaplan-Meier method was used to compare the risk of OIE between the two groups. Fixed effect models were applied to evaluate the risk factors for OIE.

RESULTS

The mean age was 36.24±15.82 years and women accounted for 88.4%. Patients with SLE had significantly increased risk of overall OIE (HR 3.89, 95% CI 3.36 to 4.50, p<0.001) as well as each OIE subtype. End-stage renal disease (ESRD; HR 2.91, 95% CI 2.05 to 4.14, p<0.001), hypertension (HR 1.77, 95% CI 1.21 to 2.58, p=0.003) and congestive heart failure (HR 1.67, 95% CI 1.12 to 2.48, p=0.01) were associated with RVO development. Hypertension (HR 2.89, 95% CI 1.10 to 3.96, p=0.02) and ischaemic stroke (HR 3.58, 95% CI 1.97 to 6.48, p<0.001) had increased risk of RAO. ESRD was associated with ION (HR 3.03, 95% CI 1.41 to 6.51, p=0.004). Intravenous steroid was associated with RVO development (HR 2.54, 95% CI 1.67 to 3.84, p<0.001).

CONCLUSIONS

SLE increases the risk of developing OIE. Systemic comorbidities and higher dosage of steroid in patients with SLE are associated with severe ocular ischaemic complications.

Posterior segment involvement in systemic lupus erythematosus - A series from South India

Purpose

To report the spectrum of posterior segment manifestations and visual outcomes in a large series of patients with systemic lupus erythematosus (SLE).

Methods

Retrospective study at a tertiary referral eye center in south India between 2016 and 2022.

Results

Charts of 109 patients diagnosed to have SLE were retrieved from our medical database. Only nine cases of SLE (8.25%) had posterior segment involvement. The male: female ratio was 1:8. The mean age was 28 years. Unilaterality was the most common presentation in eight cases (88.89%). Lupus nephritis was the most common systemic presentation in five cases (55.56%). Antiphospholipid antibodies (APLA) positivity was seen in two cases (22.22%). Ocular manifestations included microangiopathy (cotton wool spots) in one case, occlusive retinal vasculitis with cotton wool spots in four cases (five eyes), optic disc edema with combined venous and arterial occlusion (one case), central retinal vein occlusion with cotton wool spots and hemorrhages (one case), macular edema (four cases), posterior scleritis with optic disc edema and exudative retinal detachment in the posterior pole (one case), and tubercular choroidal granuloma (one case). Treatment included systemic steroids, hydroxychloroquine sulfate (HCQS), and immunosuppression in all cases, blood thinners in two cases, and laser photocoagulation in four cases. HCQS-related retinal toxicity was not seen in any of the 109 cases. Ocular manifestation was the initial presentation of SLE in one case. Visual outcome was poor in three cases.

Conclusion

Presence of posterior segment findings in cases with SLE may suggest a severe systemic disease. Early detection and aggressive treatment result in better visual outcomes. Ophthalmologists could play a vital role in guiding systemic therapy.

Optical Coherence Tomography-Based Diagnosis and Monitoring of Systemic Lupus Erythematosus-Associated Choroidopathy

A 55-year-old female presented with bilateral lower limb swelling and facial swelling along with a decreased frequency of micturition. Baseline investigations revealed an elevated serum creatinine and blood urea nitrogen. Subsequent investigations revealed a positive antinuclear antibodies (ANA) +++ (titer 1:10,000, serum immunofluorescence method) and positive anti-double-stranded DNA (dsDNA) testing. A detailed ophthalmic evaluation was performed. Her visual acuity was 6/36 improving to 6/18 in either eye. The near vision was found to be N36 without any further improvement. A dilated fundus examination revealed multiple yellowish lesions throughout the posterior pole consistent with pockets of subretinal fluid in the right eye. A swept-source optical coherence tomography (OCT) was performed that revealed the presence of fluid in both the intraretinal and subretinal spaces. A bacillary layer detachment, with the accumulation of fluid in the intraretinal space, was noted. Similar fundus findings were seen in the left eye. A decision was made to employ plasmapheresis (PLEX) along with her routine thrice-weekly hemodialysis. Additionally, the systemic steroids were continued. At her third follow-up (day 22), her vision had improved to 6/9 unaided bilaterally and to N6 with the appropriate correction. There was a near-complete regression of the exudative retinal detachments bilaterally with pigmentary changes. The OCT scans revealed significant regression of the serous retinal and retinal pigment epithelium (RPE) detachments with a thin rim of residual subretinal fluid. Fundus examination and OCT studies established the diagnosis of systemic lupus erythematosus (SLE) choroidopathy and guided its further management with systemic immunosuppression, hemodialysis and plasmapheresis. There was a rapid resolution of the retinal and choroidal findings with visual recovery over the next month.

Choroidal involvement in systemic vasculitis: a systematic review

Systemic vasculitides are a large group of heterogeneous diseases characterized by inflammatory destruction of blood vessels targeting diverse organs and tissues including the eye. As the most vascularized layer of the eye, the choroid is expected to be affected in multiple systemic rheumatologic diseases with vascular involvement. While there are plenty of studies investigating retinal vascular involvement, choroidal vascular involvement in systemic vasculitides has not been investigated in isolation. However, choroidal manifestations including thickness changes, choroidal vasculitis and ischemia may be the earliest diagnostic features of systemic vasculitic diseases. Thus, multimodal imaging of the choroid may help early detection of choroidal involvement which may also have prognostic implications in these life-threatening diseases. This article aimed to review involvement of the choroid in systemic vasculitic diseases.

Retinopathy in newly-diagnosed systemic lupus erythematosus: should we screen for ocular involvement?

Background

Ocular manifestations are common in systemic lupus erythematosus (SLE). Retinopathy has previously been linked to disease severity and might have a significant impact on the patient’s quality of life and has also been associated with a poor prognosis in SLE. This study aimed to determine the prevalence of retinopathy among patients who are newly diagnosed with SLE.

Methods

In a cross-sectional study, patients diagnosed with SLE at a tertiary referral clinic were assessed for inclusion between March 2016 and March 2017. Patients who had received treatment for SLE at any time were excluded, as well as patients with hypertension, diabetes mellitus, and coagulopathy. Clinical findings and laboratory test results were recorded, and patients were examined by an ophthalmologist for evidence of retinal pathologies. SLE disease activity index was also calculated for all patients.

Results

With 114 patients included in the final analysis, we found a prevalence of 15.8% for retinopathy among newly-diagnosed SLE patients. Cotton-wool spots were the most common finding (78%). Patients with retinopathy had significantly lower hemoglobin levels, C3 and C4 concentrations, and higher ANA and Anti-dsDNA levels. Also, patients with retinopathy had a significantly higher SLE DAI score.

Conclusions

We found a relatively high rate of retinopathy in SLE patients at the time of their initial diagnosis. Our findings suggest that retinopathy is an early manifestation of the disease. Ophthalmologic screening might be considered for SLE patients at the time of diagnosis, especially for those with severe disease. We also encourage researchers to further evaluate the correlation between retinopathy and disease activity, and the prognosis of ocular involvement.

Prevalence of dry eye in patients with systemic lupus erythematosus: a meta-analysis

OBJECTIVES

To investigate dry eye disease (DED) in patients affected by systemic lupus erythematosus (SLE).

METHODS

We conducted a systematic search of the literature on PubMed, EMBASE and the Cochrane Library databases from conception to 30 April 2020 for studies related to dry eye, secondary Sjögren's syndrome (sSS) and SLE. Original full-text articles with the number of patients diagnosed with SLE of over 15 were included. The risk of bias was evaluated with a validated critical appraisal tool which assessed study quality based on confounding factors, selection bias, bias related to measurement and bias related to data analysis. Data were extracted and pooled to evaluate the overall prevalence of DED with the random-effect model and sSS with the fixed effect model.

RESULTS

A total of 29 studies were included and 18 273 participants were involved. The pooled data showed that the overall prevalence of DED was 16% (95% CI 10% to 21%, p<0.001) in patients of SLE. Dry eye symptoms and abnormal Schirmer's test were found in 26% (95% CI 20% to 32%, p<0.001) and 24% (95% CI 14% to 34%, p<0.001) of patients with SLE, respectively. 12% (95% CI 9% to 15%, p<0.001) of patients also met the criteria of sSS. The OR of DED in patients with SLE was 4.26 (95% CI 3.47 to 5.05, p<0.001) compared with healthy controls. The meta-regression analysis showed that the sample size (p=0.004) and study location (p=0.022) could be the source of heterogeneity.

CONCLUSIONS

DED and sSS are both common in patients with SLE.

The Risks of Corneal Surface Damage in Aqueous-Deficient Dry Eye Disease: A 17-Year Population-Based Study in Taiwan

PURPOSE

To investigate the epidemiologic characteristics and risk of corneal surface damage in patients with aqueous-deficient dry eye disease (DED) in Taiwan.

DESIGN

Retrospective, population-based cohort study.

METHODS

We used claims data in the Taiwan National Health Insurance Research Database from 1997 to 2013 of patients with DED, defined according to diagnoses, drug codes, and clinical follow-up. A comparison cohort without DED was selected through propensity score matching. The main outcome measures were corneal surface damage, including corneal erosion, corneal ulcers, or corneal scars.

RESULTS

Patients with DED had a significantly higher rate of corneal surface damage (hazard ratio [HR]: 2.70; 95% confidence interval [CI] 2.38-3.06, P < .001), especially higher in patients aged <18 years (HR 6.66; 95% CI 3.58-12.41) than in older patients and in women (HR 2.98; 95% CI 2.57-3.46) than in men (HR 2.22; 95% CI 1.78-2.77), compared to those in the non-DED cohort. DED with diabetes mellitus (P = .002), rheumatoid arthritis (P = .029), or systemic lupus erythematosus (P = .005) was positively associated with corneal surface damage. The overall prevalence of DED was 7.85%, higher among women (10.49%) than men (4.92%), and increased with age (0.53%, 3.94%, 10.08%, and 20.72% for ages <18, 18-39, 40-64, and >65 years, respectively). The prevalence increased gradually during the study period.

CONCLUSIONS

The younger age group (<18 years) had the highest risk of corneal surface damage in aqueous-deficient DED. Other predisposing factors included female sex, diabetes, and autoimmune diseases. To improve clinical care, special attention is required for patients with DED with these risk factors.

Secondary angle-closure glaucoma as an ocular presentation of systemic lupus erythematosus: a case report

Systemic lupus erythematosus (SLE) is a chronic idiopathic autoimmune disease. SLE can involve almost any part of the eyes. However, bilateral angle-closure glaucoma due to lupus choroidopathy that is accompanied by polyserositis and nephropathy is rare. We report a 21-year-old woman whose clinical manifestations were diagnosed as bilateral angle-closure glaucoma caused by ciliochoroidal effusion. Subsequently, SLE and lupus nephritis were diagnosed on the basis of malar rash, photosensitivity, proteinuria, positive anti-Smith and anti-DNA antibodies, and a renal histopathological biopsy. After 1 month of treatment with steroids and immunosuppressive drugs, the patient’s intraocular pressure returned to normal, visual acuity improved, and lupus nephritis was effectively controlled. Bilateral secondary acute angle closure caused by SLE choroidal disease can be an ocular manifestation of SLE, and is usually accompanied by polyserositis and nephropathy. High-dose steroids and immunosuppressive therapy should be immediately and actively provided for this condition.
