Clinical characteristics and treatment outcomes of myopic children and adolescents with acute acquired comitant esotropia.

CLINICAL RELEVANCE: Acute acquired comitant esotropia (AACE) is becoming increasingly common in young children. Understanding clinical characteristics and treatment outcomes can inform future practice. BACKGROUND: To evaluate clinical characteristics of myopic children and adolescents with AACE, and the outcomes of varying treatments. METHODS: A retrospective review of medical records was conducted to identify patients diagnosed with AACE and diplopia between 2016 and 2020. The duration of smartphone use, angle of deviation, refractive error, stereopsis, and treatment options were analysed. The motor outcomes were evaluated at the earliest 6-month postoperative visit (6-30 months), and orthotropia or esodeviation ≤10 prism dioptres (PD) was defined as success. Successful sensory outcomes were defined as the elimination of diplopia in primary gaze or the presence of stereoacuity. RESULTS: Twelve patients diagnosed with AACE were identified. Ages were between 9 and 19 years (15.6 ± 3.3 years). All patients showed convergent and comitant esotropia ranging from 12 to 40 PD at distance fixation that was nearly equivalent for distance and near fixation. The mean age at the initial visit was 15.6 ± 3.3 years. Post-treatment esodeviations were significantly lower at both distance and near compared to pretreatment (p < 0.001, for both). Eight patients required surgery and were treated with bilateral medial rectus muscle recession, two patients were treated with botulinum toxin, and two patients were followed with prismatic glasses. Nine of 10 patients (%90) treated with either surgery or botulinum toxin had successful motor and sensory outcomes. CONCLUSIONS: Surgery is the most efficient treatment option; botulinum toxin and prismatic glasses could be useful treatment options in patients who refuse to have surgery or for whom the amount of deviation is small and variable.

Retinal vessel density and choroidal flow changes in oligoarticular juvenile idiopathic arthritis with and without uveitis.

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.

Congenital superior oblique palsy in a patient with VACTERL association.

Different types of ophthalmological defects have been reported to be accompanying vertebral anomalies, anal atresia, cardiac malformations, tracheoesophageal fistula, renal anomalies, and limb anomalies (VACTERL) association. A 7-year-old girl with a history of VACTERL association presented with upward drifting of the left eye and anomalous head posture to the right side and was diagnosed with congenital fourth nerve palsy. We report the first case representing a combination of congenital fourth nerve palsy with VACTERL association.

The effect of transepithelial corneal collagen cross-linking treatment on optical quality of the cornea in keratoconus: 12-month clinical results.

PURPOSE: To evaluate the effect of transepithelial corneal collagen crosslinking (CXL) treatment on the optical performance of the cornea at 12-month follow-up after CXL in patients with progressive keratoconus. METHODS: One hundred and ten eyes of 67 patients were included. The following corneal optical aberrations over the 4-mm-diameter pupil were recorded via Sirius dual-scanning corneal tomography: total, anterior and posterior amount of corneal higher order aberrations [HOAs], vertical coma, horizontal coma, vertical trefoil, oblique trefoil, and spherical aberration, and Strehl ratio of point spread function (PSF). RESULTS: There were significant improvements in mean root mean square error values for corneal total HOA, total coma, anterior HOA, anterior coma, and vertical coma following CXL (P > 0.05, for all). No significant changes were found in the posterior aberometric parameters. PSF value did not change after CXL (P > 0.05). The corneal topographic measurements not revealed a change in the mean simulated keratometry-1, simulated keratometry-2, and maximum keratometry compared with the baseline measurements (P > 0.05, for all). At 12 months, there was a significant improvement in the uncorrected (UCVA) and best corrected (BCVA) visual acuity (P < 0.001, both). Most corneal aberrations correlated significantly with postoperative BCVA, but changes in HOAs were not statistically associated with improvements in visual acuity. CONCLUSIONS: Transepithelial CXL was effective in stabilizing the keratometric indices and improving the most corneal aberrations in keratoconic eyes 1 year after the procedure. While the healing effect on aberrations after CXL was in total and anterior parameters, no significant changes were observed in the posterior surface. In addition, it was observed that transepithelial CXL treatment did not cause a significant change in PSF distribution data.

Monocyte-to-high-density lipoprotein ratio and systemic immune-inflammation index: Potential parameters for the evaluation of disease activity and severity in Graves' ophthalmopathy?

PURPOSE: To assess changes in monocyte-to-high-density lipoprotein (HDL) ratio (MHR), neutrophil-to-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) with Graves' ophthalmopathy (GO) and their possible relation with GO disease activity and severity. METHODS: A total of 20 patients with GO and 24 healthy controls were involved in the study. The thyroid status, MHR (monocyte count/HDL cholesterol level), NLR (neutrophil count/lymphocyte count) and SII [(neutrophil count × platelet count)/lymphocyte count] were compared between the groups. The relation of systemic inflammation parameters with disease activity and severity was evaluated. RESULTS: The mean Clinical Activity Score (CAS) was 0.75 ± 0.78 in the GO group. None of the patients were active. The severity was mild for 14 (70.0%) patients and moderate-to-severe for 6 (30.0%) patients. MHR (17.28 ± 5.56 vs. 13.28 ± 5.08), NLR (2.51 ± 1.09 vs. 1.69 ± 0.53) and SII [600.42 (391.79-837.16) vs. 413.69 (344.26-603.82)] values were significantly increased in GO patients than in the controls (p = 0.017, p = 0.005 and p = 0.036, respectively). CAS was significantly correlated with MHR (r = 0.815, p < 0.001), NLR (r = 0.768, p = 0.017) and SII (r = 0.837, p < 0.001). The severity of GO was associated with increased MHR, NLR and SII (p = 0.019, p = 0.036 and p = 0.008, respectively). ROC analysis demonstrated that MHR, NLR and SII have a good ability to differentiate GO patients from healthy individuals. CONCLUSION: GO patients have higher MHR and SII levels than healthy controls. Higher MHR, NLR and SII values were associated with increasing disease severity and activity, supporting the efficacy of these non-invasive, low-cost markers in determining the course of GO. Future prospective controlled trials are needed to elucidate the relation between inflammatory markers and GO.

Retinal and Choroidal Vascularity Evaluation in Pediatric Radiologically Isolated Syndrome and Multiple Sclerosis.

BACKGROUND: To assess vessel density (VD) and flow of retinal plexuses and peripapillary region related with the pediatric radiologically isolated syndrome (RIS) and multiple sclerosis (MS). METHODS: We analyzed 24 eyes of 12 participants with the diagnosis of RIS, 24 eyes of 12 participants with the diagnosis of MS, and 26 eyes of 13 age- and sex-matched healthy controls in this prospective, cross-sectional study. The superficial capillary plexus (SCP) and deep capillary plexus, foveal avascular zone, and the flow of choriocapillaris were investigated using optical coherence tomography angiography. RESULTS: Parafoveal VD and all subregion parameters in SCP were significantly decreased in the MS group compared with the controls, whereas only nasal and inferior VD were significantly decreased in the pediatric RIS group compared with the controls. Ganglion cell layer (GCL) thickness of all subregions of the inner ring was significantly decreased in the pediatric MS group compared with the control group. No significant difference was observed between the pediatric RIS group and the control group regarding thickness. CONCLUSIONS: We showed lower parafoveal VD in all subregions of SCP in pediatric MS, whereas only parafoveal nasal and inferior VD were decreased in pediatric RIS. GCL thickness of inner ring was significantly decreased in the pediatric MS, whereas GCL thickness did not change in pediatric RIS. Therefore, a decrease of parafoveal nasal and inferior VD without a decrease in thickness implies an early impairment of microvasculature in the RIS before impairment of thickness and that microvascular alterations begin from highly vascular superficial parafovea.

Is tear proteome profile a predictor of developing uveitis in ANA-positive patients with oligoarticular juvenile idiopathic arthritis?

PURPOSE: Although less than one-third of anti-nuclear antibody (ANA) positive patients with oJIA develop uveitis, ANA positivity is still the most well-known marker for assessing the risk of uveitis in oligoarticular JIA (oJIA). Therefore, novel biomarkers are needed to better assess the risk of developing uveitis. For this purpose, we performed a comparative tear proteome analysis of uveitis patients to reveal the identity of differentially regulated proteins. DESIGN: Tear samples were collected using the Schirmer strips in 7 oJIA and 7 oJIA patients with uveitis (oJIA-U). All oJIA-U patients had developed bilateral anterior uveitis and were inactive and topical treatment-free. METHODS: The nHPLC LC-MS/MS system was used for protein identification and label-free proteome comparisons. The PANTHER and STRING analyses were carried out using UniProt accession numbers of the identified proteins. RESULTS: Patient characteristics, e.g., age, gender, disease duration, and treatments were similar. For protein identification, three different databases were searched. Twenty-two, 147, and 258 database searches, respectively. Of these, 15 were common to all three proteome databases. Of these 15 proteins, 10 proteins were upregulated, and 2 were downregulated, based on the twofold regulation criteria. The upregulated proteins were, namely, cystatin-S, secretoglobin family 1D member, opiorphin prepropeptide, mammaglobin-B, lysozyme C, mesothelin, immunoglobulin kappa constant, extracellular glycoprotein lacritin, beta-2-microglobulin, and immunoglobulin J chain. The downregulated proteins were dermcidin and prolactin-inducible protein. Among the differentially regulated proteins, cystatin-S was the most regulated protein with an 18-fold upregulation ratio in tear samples from uveitis patients. CONCLUSION: Here, the identities and regulation ratios of several proteins were revealed when tear samples from uveitis patients were compared to patients without uveitis. These proteins are putative biomarkers for assessing uveitis risk and require further attention.

Idiopathic Orbital Inflammatory Disease Attack Associated with Large Serous Detachment Without Anterior and Posterior Segment Inflammation.

Idiopathic orbital inflammatory disease is a benign, non-infectious, and non-neoplastic space-occupying orbital and peri-orbital inflammation with no identifiable local or systemic causes. Patients usually present with eyelid and periorbital erythema and edema, proptosis, and decreased eye movements. In this report, a case of large serous retinal detachment accompanying a unilateral idiopathic orbital inflammatory disease attack is discussed. It demonstrates that very extensive and highly serous retinal detachment may accompany idiopathic orbital inflammatory disease attacks. Dramatic improvement in clinical findings and imaging can be observed with high-dose steroid treatment in a short time.

Comparative Proteomic Analysis of the Aqueous Humor from Patients with Pseudoexfoliation Syndrome.

Purpose: The goal of this study was to pinpoint potential molecular pathways that may have contributed to the onset of pseudoexfoliation syndrome (PEX), a systemic illness associated with aging that has no known cause and is brought on by the deposition of fibrillary white flaky debris in ocular tissues. Materials and methods: Protein pools representing each group were created using two-dimensional gel electrophoresis (2DE) in conjunction with a matrix-assisted laser desorption ionization-time of flight/time of flight (MALDI-TOF/TOF) mass spectrometer. Aqueous humor (AH) from patients with PEX and cataracts was also collected for a comprehensive study of the data; ingenuity pathway analysis (IPA) was used for the discovered proteins. Results: In comparison to controls, 2DE showed that 10 sites in PEX patients had differently altered gene expression. Two of these proteins, transthyretin (TTR) and apolipoprotein A4 (ApoA4) were significantly overexpressed in PEX patients, but the remaining proteins were only mildly altered. The liver X receptor (LXR) and the retinoid X receptors (RXR) may play a crucial role in the pathophysiology of PEX according to IPA employing these 10 proteins. Conclusion: The altered proteins, particularly ApoA4 and TTR, may be important in revealing the molecular process behind PEX, as anticipated by IPA.

Decrease of over-elevation in adduction after surgery of medial rectus muscles in partially refractive accommodative esotropia.

SIGNIFICANCE: The course of over-elevation in adduction after strabismus surgery has been evaluated in a small number of research in the literature, we believe our study is the first to report the results in a specific group of esotropia (ET) patients. AIM: To report the course of postoperative over-elevation in adduction in patients who underwent surgery for horizontal deviation on the medial recti in partially accommodative ET. METHODS: The medical charts of patients who had partially accommodative ET with over-elevation in adduction were reviewed retrospectively. A scale from -4 to +4 was used to grade the oblique muscle function. Among these, 17 patients who were operated solely on the horizontal rectus muscles were identified. The primary outcome measure was the degree of improvement in over-elevation in adduction after medial rectus surgery. RESULTS: Nine (52.9%) of the 17 patients (mean age: 5.18 ± 2.24 months) were males and 8 (47.1%) were females. The mean follow-up period was 17.06 ± 15.32 months. Overall, 15 patients (88.2%) achieved surgical success. The mean inferior oblique overaction was found 1.44 ± 0.56 preoperatively and the final postoperative mean inferior oblique overaction was 0.53 ± 0.51 (P = 0.001). Postoperative over-elevation in adduction after 3 months was significantly decreased compared to the preoperative value (P = 0.003, P = 0.001, P = 0.001 at 3rd and 6th months and final visits respectively). CONCLUSION: Over-elevation in adduction accompanying partially refractive accommodative ET seems to regress after medial rectus weakening surgery. This finding should be considered in the presurgical evaluation of these patients.

Suprachoroidal spheroidal mesenchymal stem cell implantation in retinitis pigmentosa: clinical results of 6 months follow-up.

PURPOSE: This prospective clinical case series aimed to evaluate the effect of suprachoroidal implantation of mesenchymal stem cells (MSCs) in the form of spheroids as a stem cell therapy for retinitis pigmentosa (RP) patients with relatively good visual acuity. METHODS: Fifteen eyes of 15 patients with RP who received suprachoroidal implantation of MSCs in the form of spheroids were included. Best-corrected visual acuity (BCVA), 10-2 and 30-2 visual field examination and multifocal electroretinography (mfERG) recordings were recorded at baseline, postoperative 1st, 3rd and 6th months during follow-up. RESULTS: Baseline median BCVA of RP patients was 1.30 (1.00-2.00) logMAR. BCVA has improved to 1.00 (0.50-1.30), 0.80 (0.40-1.30) and 0.80 (0.40-1.30) at the postoperative 1st, 3rd and 6th months, respectively. The improvements from baseline to the 3rd and 6th months were statistically significant (p = 0.03 and p < 0.001, respectively). In the 30-2 VF test, median MD was significantly improved at the 6th month compared to baseline (p = 0.030). In the 10-2 VF test, the median MD value was significantly different at the 6th month compared to the baseline (p = 0.043). The PSD value of the 10-2 VF test was significantly different at the 6th month compared to the 3rd month (p = 0.043). The amplitudes of P1 waves in < 2°, 5°-10° and 10°-15° rings improved significantly at the postoperative 6th month (p = 0.014, p = 0.018 and p = 0.017, respectively). There was also a statistically significant improvement in implicit times of P1 waves in 10°-15° ring at the postoperative 6th month (p = 0.004). CONCLUSION: Suprachoroidal implantation of MSCs in the form of spheroids as a stem cell therapy for RP patients with relatively good visual acuity has an improving effect on BCVA, VF and mfERG recordings during the 6-month follow-up period. Spheroidal MSCs with enhanced effects may be more successful in preventing apoptosis and improving retinal tissue healing in RP patients.

Pseudoexfoliation Glaucoma: Clinical Presentation and Therapeutic Options.

Pseudoexfoliation syndrome (PES) is one of the most common causes of open-angle glaucoma, with a higher risk of vision loss, a higher maximum and mean intraocular pressure (IOP) at diagnosis, and a wider range of IOP fluctuation compared to primary open-angle glaucoma. Patients with this syndrome have a ten-fold higher risk of developing glaucoma than the normal population. A definite diagnosis can be made by the observation of pseudoexfoliation material (PEM) on the anterior lens surface, ciliary processes, zonules, and iris. PEM deposits on the zonules may explain the clinically observed zonular weakness and lens subluxation or dislocation. An increased incidence of cataract development is also associated with PES. There is growing evidence for systemic associations of PES with peripheral, cardiovascular, and cerebrovascular system diseases, Alzheimer's disease, hearing loss, and increased plasma homocysteine levels. Indications for surgery are markedly more common in patients with pseudoexfoliation glaucoma than primary open-angle glaucoma. The goal of this article is to review the latest perspectives on the clinical features, therapy, and systemic associations of this clinically and biologically challenging disease.

Quantitative analysis of preclinical ocular microvascular changes in Multisystemic Inflammatory Syndrome in Children (MIS-C) detected by optical coherence tomography angiography.

OBJECTIVES: To evaluate the macular and optic nerve head (ONH) vascular density, foveal avascular zone area, and outer retina and choriocapillaris flow in Multisystemic Inflammatory Syndrome in Children (MIS-C) using optical coherence tomography angiography (OCTA). METHODS: Thirty-four eyes of 34 patients with MIS-C and 36 age and sex-matched healthy controls were investigated in this prospective, cross-sectional study. The superficial capillary plexus (SCP) and deep capillary plexus (DCP), ONH, FAZ parameters, the flow area of the outer retina, and choriocapillaris were evaluated using OCTA. RESULTS: All VD parameters in SCP were significantly lower in MIS-C patients. There was no significant difference between the groups in VD parameters of both DCP and ONH, as well as FAZ area and FAZ perimeter. However, foveal density (FD-300) was significantly decreased in the MIS-C group. (p = 0.024). The outer retina flow area at 1 mm, 2 mm, and 3 mm radius and CC flow area at 1 mm and 2 mm radius were significantly lower in the MIS-C group than in the control group. Although CC flow area at 3 mm radius was decreased in the MIS-C group compared to healthy controls, the difference was not statistically significant. CONCLUSIONS: We demonstrated a decreased vessel density in SCP, choriocapillaris flow area, and outer retinal flow area in MIS-C patients. Hence, we proposed that OCTA could reveal retinal and choroidal microvascular changes in MIS-C patients who were completely healthy before the diagnosis of MIS-C.

In vivo confocal microscopy of corneal nerve fiber damage in early course of multiple sclerosis.

PURPOSE: To evaluate the corneal nerve fiber morphology in patients with multiple sclerosis (MS) by in vivo corneal confocal microscopy (CCM). METHODS: Retinal nerve fiber layer thickness (RNFLT), central macular thickness (CMT), corneal nerve fiber length (CNFL), corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD) and corneal nerve fiber tortuosity (CNFT) were measured. Correlation of corneal nerve findings with duration and clinical severity of MS was calculated. RESULTS: CNFL (9.50 ± 0.60 vs. 11.20 ± 0.57 mm/mm2, P = 0.046) and CNBD (57.46 ± 5.04 vs. 77.65 ± 3.41 no/mm2, P = 0.001) were significantly lower with no significant difference in CNFD (21.24 ± 1.20 vs. 23.62 ± 0.95 no/mm2, P = 0.125), CNFT (2.00 ± 0.15 vs. 1.73 ± 0.12, P = 0.180), CMT (269.57 ± 12.53 vs. 271.10 ± 18.84 µm, P = 0.716) or RNFLT (102.82 ± 6.98 vs. 105.33 ± 12.70 µm, P = 0.351) between patients with RRMS compared to controls. There was no significant correlation between CCM parameters with EDSS and duration of disease in MS patients. CONCLUSION: The current study demonstrated that a decrease in CNFL, CNFD and CNBD in CCM analysis in the early course of MS.

Subclinical Retinal Capillary Abnormalities in Juvenile Systemic Lupus Erythematosus without Ocular Involvement.

PURPOSE: This study aimed to evaluate subclinical retinal microvascular changes with OCTA in juvenile systemic lupus erythematosus (JSLE) patients without ocular involvement. METHODS: Ten eyes of 10 JSLE and 13 eyes of 13 age and sex-matched healthy controls (HCs) were enrolled. The superficial (SCP) and deep capillary plexus (DCP), FAZ parameters, the flow area of the outer retina, and choriocapillaris were evaluated using OCTA. RESULTS: All vessel density (VD) parameters in DCP were significantly lower in JSLE group compared to HCs. There was no significant difference between the groups in VD parameters of both SCP and ONH, FAZ, outer retina and choriocapillaris flow area. All DCP VD parameters showed a good ability to differentiate JSLE from HCs. CONCLUSION: OCTA could detect retinal vascular impairment in the deep macular region in JSLE patients with normal ocular examination. Furthermore, all DCP VD parameters have a good ability to discriminate JSLE from HCs.

Is Corneal Subbasal Nerve Loss Associated With Meibomian Gland Loss in Inactive Mild and Moderate-to-Severe Graves' Ophthalmopathy?

PURPOSE: To evaluate meibomian gland and subbasal nerve plexus parameters in Graves' Ophthalmopathy (GO) and association of meibomian gland loss with corneal subbasal nerve plexus loss. METHODS: Fifty-two eyes of 52 mild and moderate-to-severe GO patients and 32 eyes of 32 healthy controls were enrolled. The meibomian gland dropout area (MGDA) and meibography scores were evaluated using noncontact meibography. In vivo confocal microscopy of corneal subbasal nerve plexus were conducted. ACCMetrics was used to obtain corneal parameters. RESULTS: Compared with healthy subjects, GO patients had worse upper and lower eyelid MGDA ( p < 0.001, for all) and upper, lower and total meibography scores ( p < 0.001, p = 0.001, and p < 0.001, respectively). Eyelid margin scores were worse in the GO group ( p < 0.001) and showed correlation with all noncontact meibography parameters ( p < 0.001 for all). All corneal subbasal nerve parameters were significantly lower in the GO group compared with the controls ( p < 0.05 for all). Subbasal nerve parameters of GO patients did not reveal a correlation with MGDA and meibography scores but showed correlations with ocular surface disease index score and Schirmer I test (r = -0.304; p = 0.042 and r = 0.336; p = 0.021, respectively). CONCLUSION: Meibomian gland and corneal nerve loss could be observed even in the inactive phase and mild GO. The lack of a correlation between meibomian gland loss and subbasal nerve loss suggests that meibomian gland loss is not a significant additional component in the pathogenesis of subbasal nerve damage in GO. Furthermore, our study revealed new evidence regarding the use of eyelid margin score to represent meibomian gland loss in GO.

Analysis of Meibomian Glands in Juvenile Systemic Lupus Erythematosus Patients without Dry Eye Symptoms and Signs.

PURPOSE: To evaluate meibomian gland loss and its possible association with disease duration and activity in Juvenile Systemic Lupus Erythematosus (JSLE) patients' without dry eye symptoms or signs. STUDY DESIGN: Prospective clinical study. METHODS: Ten eyes of 10 JSLE patients were evaluated using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and 14 eyes of 14 healthy controls were also enrolled. Ocular Surface Disease Index (OSDI) questionnaire and Schirmer I test were performed. Lid margin score, meibum quality and expressibility scores were evaluated. Noninvasive first breakup time (NIF-BUT) and noninvasive average breakup time (NIAvg-BUT), meibomian gland dropout area (MGDA) and meibography scores were evaluated using non-contact meibography (Sirius; CSO). RESULTS: There was no significant difference between the JSLE patients and the healthy controls in the OSDI, NIF-BUT, NIAvg-BUT and Schirmer I tests. Also lid margin score, meibum quality and expressibility scores were not significantly different between the groups. However, JSLE patients had increased upper and lower lid MGDA and increased upper lid, lower lid and total meibography scores compared to the healthy subjects. Furthermore, the duration of JSLE showed a high positive correlation with upper and lower lid MGDA and meibography scores. CONCLUSION: Meibomian gland loss could be observed in JSLE patients with no clinical signs and symptoms of dry eye. Considering the longer life expectancy of children, the positive correlation of disease duration with the meibomian gland reveals the importance of routine eye examinations from the diagnosis of the disease.

The Effect of Radiologically Isolated Syndrome on Retinal and Choroidal Hemodynamics - An Optical Coherence Tomography Angiography Study.

PURPOSE: To evaluate vessel density of retinal plexuses and optic nerve head (ONH) and flow of choriocapillaris to detect possible subclinical retinal microvascular changes associated with the radiologically isolated syndrome (RIS). METHODS: We analyzed 26 eyes of 26 participants diagnosed with RIS and 39 age and sex-matched healthy controls in this prospective, cross-sectional study. The superficial (SCP) and deep capillary plexus (DCP), foveal avascular zone (FAZ) parameters, and the flow area of choriocapillaris were evaluated using optical coherence tomography angiography (OCTA). RESULTS: Vessel density (VD) of the parafovea (p = .045) and parafoveal subregions (p = .049 for superior hemifield, p = .016 for inferior hemifield, p = .038 for superior, p = .033 for nasal, p = .042 for inferior, and p = .005 for temporal) in SCP were significantly lower in the RIS group. There was no significant difference between the groups in VD parameters of both DCP and ONH, FAZ parameters, and choriocapillaris flow area as well as thickness parameters. (p > .05 for all). ROC analysis revealed that SCP para inferior hemifield VD, SCP para superior VD, SCP para nasal VD, and SCP para temporal VD showed good ability to differentiate RIS from healthy controls (p = .023, p = .035, p = .028, and p = .008, respectively). CONCLUSIONS: We demonstrated a decreased vessel density in the superficial parafoveal region in RIS. Hence, we propose that changes in parafoveal vessel density imply an early impairment in RIS and microvascular changes start from the vascular-rich superficial parafoveal area. Furthermore, SCP para inferior hemifield VD, SCP para superior VD, SCP para nasal VD and SCP para temporal VD parameters have a good ability to discriminate RIS from healthy controls.

Preclinical ocular microvascular changes in juvenile dermatomyositis: A pilot optical coherence tomography angiography study.

OBJECTIVES: To evaluate the macular and optic nerve head (ONH) vascular density, foveal avascular zone area, and outer retina and choriocapillaris flow in juvenile dermatomyositis (JDM) using optical coherence tomography angiography (OCTA). METHODS: Ten eyes of 10 patients with JDM and 15 age and sex-matched healthy controls were investigated in this prospective, cross-sectional study. 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 using OCTA. RESULTS: Vessel density (VD) of the parafovea (p = 0.036) and parafoveal subregions (p = 0.041 for superior hemifield, p = 0.031 for inferior hemifield, p = 0.012 for superior, p = 0.019 for nasal, p = 0.026 for inferior, and p = 0.048 for temporal) in DCP were significantly lower in the JDM group compared to healthy controls. A high inverse correlation between disease duration and these parameters was found except parafoveal superior VD in DCP. There was no significant difference between the groups in VD parameters of SCP and ONH, FAZ parameters, outer retina, and choriocapillaris flow area as well as thickness parameters. (p > 0.05 for all). Furthermore, ROC analysis revealed that all parafoveal DCP parameters showed good ability to differentiate JDM from healthy controls. CONCLUSIONS: We demonstrated a decreased vessel density in the deep parafoveal region in JDM. As a result, we hypothesized that OCTA could detect retinal microvascular changes in JDM patients who did not have clinical evidence of ocular involvement.

Evaluation of macular and peripapillary vascular parameter change in healthy subjects after caffeine intake using optical coherence tomography angiography.

PURPOSE: To observe the effects of caffeine intake on vessel densities in macular and peripapillary regions and to analyze the correlations of vascular properties of these two interlinked regions in healthy volunteers using optical coherence tomography angiography (OCTA). METHODS: In this prospective randomized, double-masked, placebo-controlled study, 120 participants were grouped into two groups: sixty subjects as a study group, which received caffeine and sixty subjects as a placebo group, which received a placebo. OCTA imaging was performed at baseline and 1 h after drug intake. Changes in macular and radial peripapillary capillary (RPC) vessel densities (VD) and foveal avascular zone (FAZ) parameters and correlation of these parameters were analyzed. RESULTS: Baseline macular and RPC VD and FAZ parameters showed no significant difference between study and placebo groups (P > 0.05 for all). VD parameters in all segments of superficial and deep macular regions and peripapillary region showed a statistically significant decrease after caffeine intake (P < 0.001 for all). All macular superficial VD parameters showed a positive correlation with deep perifovea VD (P < 0.05 for all). Also, superficial perifovea VD was positively correlated with all deep macular VD parameters except deep fovea VD (P < 0.05 for all). CONCLUSION: We show that caffeine causes a decrease in macular and peripapillary vessel densities in healthy subjects, and correlations were observed between macular and peripapillary VD parameters. We believe that future studies are needed to support the effect of caffeine on peripapillary VD and the idea of using deep perifovea VD as the main parameter to estimate superficial macular parameters.
