The aim of this study was to conduct a detailed ophthalmological examination in children with systemic lupus erythematosus (jSLE), including choroidal thickness (ChT), choroidal vascularity index (CVI) and peripapillary retinal nerve fiber layer (RNFL). The study included all jSLE patients (n = 21) diagnosed according to the Systemic Lupus International Collaborating Clinics classification criteria between January 2017 and April 2017, and an age- and gender-matched control group (n = 21). The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) was used to assess disease activity. After routine eye examinations, ChT at five points (750 µ and 1500 µ from the center of the fovea both in the temporal and nasal quadrants and under the fovea), total subfoveal choroidal area (TCA), luminal area (LA), stromal area (SA), CVI and RNFL thickness at the optic disc were evaluated. One patient had active ocular involvement in the form of episcleritis. Another patient had corticosteroid-induced cataract. The median age of the patients was 16 years (6-19 years). ChT at five points, TCA, LA and SA were found to be higher in patients with jSLE, whereas RNFL thickness and CVI were similar to those of the healthy control individuals. No correlation was determined between optical coherence tomography findings, SLEDAI and the immunological parameters (antinuclear antibodies, anti-double-stranded DNA, complements 3 and 4, extracted nuclear antigen antibody, antiphospholipid antibody). Intraretinal and subretinal fluid was not present in any of the patients. The choroid was thicker in patients with jSLE than in the control group. The study results suggest that jSLE may affect the choroid. Ophthalmological evaluation is important in SLE patients, even in the absence of relevant complaints.

BACKGROUND AND OBJECTIVE: To evaluate the effects of obesity on choroidal thickness (CT) in childhood. PATIENTS AND METHODS: Forty-four patients with obesity (study group) and 42 healthy children (control group) were enrolled in the study. Subjects underwent a complete ocular examination. The mean CT was measured by enhanced depth imaging optical coherence tomography (EDI-OCT). Body mass index (BMI) was calculated. RESULTS: Mean BMI value was 31.8 ± 1.9 in the study group and 19.8 ± 4.4 in the control group. The mean subfoveal CT value 385.77 µm ± 6.09 µm in the study group and 348.43 µm ± 73.21 µm in the control group. There was a significant difference between the study and control groups with regard to subfoveal CT ( P = .017). Subfoveal CT and BMI were positively correlated (r = 0.288; P = .004). CONCLUSIONS: CT increases in childhood obesity. Findings revealed that adiposity causes a significant increase in CT, and it may be related to ocular complications.

Background/purpose: To assess EDI-OCT (enhanced depth imaging optical coherence tomography) of choroid for inflammatory signs in children with polyarteritis nodosa (PAN) and adenosine deaminase-2 deficiency (DADA-2). Methods: In this cross-sectional study conducted between June 2017 and September 2018, we evaluated children diagnosed with PAN (n = 11) and DADA-2 (n = 4) and an age- and sex-matched control group (n = 15). Demographic and laboratory data were retrospectively analyzed from patient charts. Disease activity was assessed using the pediatric vasculitis activity score (PVAS). Choroidal images were obtained with spectral domain-OCT to measure choroidal thickness (ChT) at 5 points (750 and 1500 μm from the foveal center in the temporal and nasal quadrants and beneath the fovea), and to calculate the total subfoveal choroidal area (TCA), luminal area (LA), stromal area (SA), and the choroidal vascularity index (CVI). Results: The median (min-max) age was 8 (4–16) years in PAN patients, 6 (5–16) years in DADA-2 patients and 8 (8–10) years in control group at the OCT visit (p = 0.214). The ChT at 3 points and the TCA, LA, and SA were higher in children with both PAN and DADA-2 patients compared to those of the control group (p < 0.0001, p = 0.049, p = 0.007, p = 0.007, p = 0.006, p = 0.033, respectively). The CVI was similar in both groups. No association was observed between the OCT findings, PVAS, and the erythrocyte sedimentation rate, and serum leukocyte and C-reactive protein levels. Conclusion: Similar CVI scores were obtained from PAN and DADA2 patients under treatment and from healthy controls. Increased subfoveal ChT without any other signs of ocular involvement may suggest choroidal thickening as a sign of mild subclinical inflammation.

We aimed to assess the association between retinal vascular caliber (RVC) scores and disease activity in rheumatoid arthritis (RA) patients. Forty-seven RA patients, 32 systemic lupus erythematosus (SLE) patients, and 45 healthy people were enrolled. RA and SLE patients were subdivided into groups according to C-reactive protein (CRP) levels. RA patients were also grouped according to Disease Activity Score-28 (DAS-28). Fundus photography was performed for all patients. RVC was summarized as the central retinal artery and vein equivalents (CRAE and CRVE). Mean CRVE for RA patients was 213.3 ± 17.8 μm compared with 209.2 ± 14.1 μm for SLE and 217.5 ± 26.2 μm for the control group (P = 0.17). RVC scores did not differ between the CRP-high and CRP-low groups. As the RA disease activity increased, the widening of CRVE became more prominent and statistically significant. When the DAS-28 > 5.1 (CRVE, 220.4 (211.8–246.5) μm) group and DAS-28 ≤ 3.2 (CRVE, 214.4 (172.4–242.3) μm) group were compared, statistical significance was more pronounced (P = 0.03) than when comparing the DAS-28 > 3.2 and DAS-28 ≤ 3.2 groups (P = 0.05). CRVE, which reflects systemic inflammation and possibly increased cardiovascular risk, was significantly increased in active RA patients. The association between retinal venular widening and disease activity, regardless of CRP, may be a sign that RA-related inflammation may have systemic vascular effects even with normal levels of CRP.

Objective: This study aimed to evaluate the impact of anti-TNF (biological) therapies on the incidence and progression of diabetic retinopathy. Materials and methods: A cross-sectional analysis of 50 diabetic patients with rheumatic diseases (group 1) was performed. An age-, sex-, and HbA1c-matched control group (group 2) was formed from a pool of diabetic patients who underwent regular eye examinations. The presence or absence of diabetic retinopathy was also assessed. Comorbidities such as hypertension, coronary artery disease, and hyperlipidemia were also evaluated as possible confounding factors. Results: Hundred eyes of 50 patients were evaluated in each group. Only three patients in group 1 had non-proliferative retinopathy. The median duration of rheumatic disease was 9 years, whereas that of diabetes was 11 years. The mean duration of anti-TNF therapy was 4 years. In the control group of diabetes-only patients, 13 patients developed some form of newly diagnosed diabetic retinopathy during the last five years. The calculated retinopathy occurrence between the groups was statistically significant (p < 0.05). In this study, the incidence rate ratio for patients receiving anti-TNF treatment was calculated as 0.4 in the study. Conclusion: TNF inhibitors, with their anti-inflammatory effects, positively impact diabetic complications by reducing the incidence of retinopathy. To our knowledge, this is the first study to evaluate retinopathy development after anti-TNF therapy.
