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 2024:104263. [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] [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 guides the treatment process of this patient.

Abstract
PURPOSE To evaluate microvasculature alterations of the peripapillary retina and macula and to assess whether the changes can detect preclinical retinopathy in systemic lupus erythematosus patients. METHODS Cross-sectional study of 32 systemic lupus erythematosus patients without retinopathy and 22 normal controls. Optical coherence tomography angiography was used to measure the microvasculature of the peripapillary retina and macula. Vessel densities (VD, %) and fractal dimensions of superficial capillary plexus (SCP) and deep capillary plexus were calculated. RESULTS Compared with controls, macular vessel densities of the whole image SCP (macular vessel density of SCP-wi) and macular vessel density of inferior SCP (macular vessel density of SCP-i) were significantly reduced in systemic lupus erythematosus patients ( P < 0.05). The peripapillary vessel densities (peripapillary vessel density [pVD]) of a 2.5-mm circle of SCP (pVD of SCP Φ2.5 ), pVD of SCP Φ3.5 , and pVD of inferior region of the inner circle of SCP (pVD of SCP-ii) were significantly reduced in patients treated with hydroxychloroquine >5 years. Macular vessel density of SCP-wi declined with age (β = -0.12; P < 0.01) and pVD of SCP-ii declined with hydroxychloroquine cumulative dose (β = -0.01; P < 0.01). Macular vessel density of SCP-i had the best discrimination power of 0.77 ( P < 0.01). CONCLUSION Systemic lupus erythematosus patients without ocular involvement had microvasculature alterations that were particularly evident in the SCP. Peripapillary retina microvasculature may be reduced in patients with longer hydroxychloroquine treatment.

Abstract
Purpose The aim of this study is to measure retinal vessel density and flow rate area by optical coherence tomography angiography (OCTA) in patients with autoimmune diseases taking hydroxychloroquine (HCQ). Methods The cross-sectional study included 98 patients divided into three groups. Group I included patients with the diagnosis of an autoimmune disease, for whom the introduction of HCQ was planned. Group II implied low-risk patients for retinal toxicity (≤5 years of HCQ use), whereas Group III implied patients that were at high-risk (>5 years of drug use). All patients underwent a computerized visual field, central macular thickness by optical coherence tomography, and OCTA measurements. Results The vascular density was found to be statistically significantly decreased in the high-risk group compared to the control group in the superficial parafoveal zone (P = 0.030), whereas it was decreased compared to the low-risk and control groups in the deep layers whole (P = 0.006, P = 0.010, respectively) and perifoveal zones (P = 0.003, P = 0.010, respectively). The foveal avascular zone was significantly enlarged in the high-risk group compared to the control (P < 0.018). Retinal flow rates did not show statistically significant differences between the groups (P > 0.05). Conclusion Patients treated with HCQ for more than 5 appear have a significant loss of vascular density in the parafoveal and perifoveal regions, and FAZ area is significantly increased compared to low-risk patients and controls. These findings indicate that OCTA may be beneficial for monitoring high-risk patients and may stratify their risk of further retinal damage.

Abstract
This review provides an overview of conventional and novel retinal imaging modalities for hydroxychloroquine (HCQ) retinopathy. HCQ retinopathy is a form of toxic retinopathy resulting from HCQ use for a variety of autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus. Each imaging modality detects a different aspect of HCQ retinopathy and shows a unique complement of structural changes. Conventionally, spectral-domain optical coherence tomography (SD-OCT), which shows loss or attenuation of the outer retina and/or retinal pigment epithelium-Bruch's membrane complex, and fundus autofluorescence (FAF), which shows parafoveal or pericentral abnormalities, are used to assess HCQ retinopathy. Additionally, several variations of OCT (retinal and choroidal thickness measurements, choroidal vascularity index, widefield OCT, en face imaging, minimum intensity analysis, and artificial intelligence techniques) and FAF techniques (quantitative FAF, near-infrared FAF, fluorescence lifetime imaging ophthalmoscopy, and widefield FAF) have been applied to assess HCQ retinopathy. Other novel retinal imaging techniques that are being studied for early detection of HCQ retinopathy include OCT angiography, multicolour imaging, adaptive optics, and retromode imaging, although further testing is required for validation.

Abstract
BACKGROUND To identify factors differently affecting the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in healthy eyes using their vessel density (VD) ratio. METHODS Healthy eyes were enrolled. The ratio between the VD of SCP and DCP (SVD/DVD ratio) was calculated. Pearson correlation analyses were performed to identify the relationships between this ratio and other factors. RESULTS The mean SVD and DVD were 36.2 ± 5.7 and 37.7 ± 4.9%, respectively, and the mean SVD/DVD ratio was 0.96 ± 0.15. The SVD was significantly correlated with the best-corrected visual acuity (BCVA) (r = - 0.368, P < 0.001), age (r = - 0.408, P < 0.001), and OCTA quality (r = 0.520, P < 0.001). The DVD was significantly correlated with the BCVA (r = - 0.150, P = 0.008), age (r = - 0.229, P < 0.001), and OCTA quality (r = 0.555, P < 0.001). Among various factors, age (r = - 0.296, P < 0.001), the BCVA (r = - 0.237, P < 0.001), axial length (r = 0.234, P < 0.001), and OCTA quality (r = 0.270, P < 0.001) were significantly correlated with the SVD/DVD ratio. CONCLUSIONS Age, BCVA, axial length, and OCTA image quality were significantly correlated with the SVD/DVD ratio. Age, the BCVA, and OCTA quality were more strongly correlated with the SCP, and the axial length was more strongly correlated with the DCP.

Abstract
INTRODUCTION There is only a unique report with a small sample size studying hydroxychloroquine (HCQ) retinal toxicity with swept-source (SS) optical coherence tomography angiography (OCTA). The aim of this study was to quantify OCTA quantitative parameters in patients who underwent HCQ therapy. METHODS We conducted a retrospective study. The study included 43 eyes of 22 patients taking HCQ for more than 5 years (high-risk group), 57 eyes of 29 patients taking HCQ for 5 years or less (low-risk group) and 25 eyes of 50 age-matched healthy controls. OCTA quantitative parameters (vessel density (VD) and foveal avascular zone (FAZ) area in superficial capillary plexus (SCP), middle capillary plexus (MCP), deep capillary plexus (DCP), total capillary plexus (TCP), and choriocapillaris (CC)) were recorded. RESULTS In the low-risk group, VD in the SCP and MCP was increased compared to control group (p value <.05). In the high-risk group, VD in the SCP, MCP and TCP was increased (p value <.05). The subgroup analysis revealed an increased VD at SCP in systemic lupus erythematosus (SLE) high-risk patients, an increased VD at TCP and CC in rheumatoid arthritis (RA) high-risk subjects, and a decreased VD at CC level in the high-risk group patients with Sjögren's syndrome (SS) and connective tissue disease (CTD) (p value <.05). Furthermore, we demonstrated a significant enlargement of FAZ area at MCP level in the high-risk group patients with SS and CTD (p value <.05). CONCLUSION We demonstrated an increase of VD in patients who underwent HCQ treatment, so we suggest that HCQ retinal toxicity is not vascular mediated.

Abstract
Hydroxychloroquine retinopathy is an increasingly recognized cause of iatrogenic, irreversible visual impairment due to the expanding use of hydroxychloroquine in combination with improvements in disease detection following advances in retinal imaging techniques. The prevalence of disease is estimated to be greater than 5% amongst individuals who have used the drug for 5 years or more. In addition to conventional imaging modalities, such as spectral-domain optical coherence tomography (OCT) and fundus autofluorescence (FAF), novel retinal imaging techniques such as en face OCT, OCT angiography, fluorescence lifetime imaging ophthalmoscopy, quantitative autofluorescence, and retromode imaging are capable of detecting structural changes in the retina. These novel retinal imaging techniques have shown promise in detecting earlier disease than is possible with current mainstream imaging modalities. Moreover, these techniques may identify disease progression as well as enabling functional correlation. In the future, these novel imaging techniques may further reduce the risk of visual loss from hydroxychloroquine retinopathy through the earlier detection of pre-clinical disease.
