Vision-Related Quality of Life in Patients with Systemic Lupus Erythematosus.

PURPOSE: To assess vision-related quality of life (VRQoL) in patients with systemic lupus erythematosus (SLE) under treatment with hydroxychloroquine (HCQ), and to find the influencing factors. METHODS: Cross-sectional study enrolling SLE patients for less than ten years (Group 1), SLE patients for more than ten years (Group 2), and healthy controls (Group 3). SLE patients should be under treatment with HCQ but without ophthalmological affection. Schirmer test, best-corrected visual acuity (BCVA), axial length (AL) with optical biometry, and swept-source optical coherence tomography-angiography (OCTA) Triton (Topcon) were performed. All participants fulfilled the Impact of Visual Impairment questionnaire, and SLE patients answered the Lupus Impact Tracker (LIT) questionnaire. Additional data were obtained from clinical records. RESULTS: A totals of 41 eyes (41 patients), 31 eyes (31 patients) and 45 eyes (45 volunteers) were enrolled in the study groups. The mean ages were 41.09 ± 9.56, 45.06 ± 8.47 and 40.25 ± 10.83 years, respectively (p = 0.10). The LIT outcomes were 33.49 ± 20.74 and 35.98 ± 22.66 (p = 0.63), respectively. Group 3 referred to a better VRQoL than Group 2 in all categories and than Group 1 in some of them. A linear regression analysis showed that serum ferritin, SLE activity scales, body-mass index (BMI), age, and BCVA influenced VRQoL. The LIT questionnaire was correlated to two categories of the Impact of Visual Impairment questionnaire (IVI). CONCLUSIONS: Despite no ophthalmological affection, SLE patients refer to poorer VRQoL because of disease activity and a low health-related quality of life, which has a negative influence on VRQoL. This masks the effect of other ophthalmological conditions such as dry eyes. Other variables influencing VRQoL are age and BMI, and BCVA, to a lesser extent.

Relación del tratamiento y coste con la ganancia de agudeza visual en la degeneración macular asociada a la edad / Relationship between treatment and cost with visual acuity improvement in age-related macular degeneration

Fundamento. Relacionar la ganancia de agudeza visual (AV) con el coste asistencial y de tratamiento con terapia anti-factor de cre-cimiento endotelial vascular (antiVEGF) en pacientes diagnostica-dos de degeneración macular asociada a la edad exudativa (DMAE exudativa).Pacientes y métodos. Estudio observacional, longitudinal, retros-pectivo, de pacientes ≥50 años diagnosticados de DMAE exudativa, con AV logMAR entre 0,6 y 0,06, en seguimiento y tratamiento en nuestro hospital de tercer nivel entre el 01/01/2014 y el 31/12/2018.Resultados. Se incluyeron 778 pacientes, 62,2% mujeres y media de edad 79,83±7,94 años, con 957 ojos con DMAE exudativa. La AV final global (0,65±0,45) aumentó un 3,2% respecto de la inicial. El 60,3% de los ojos recibieron antiVEGF con ranibizumab, el 10,2% con aflibercept y el 29,5% con ambos (mixto). El grupo mixto in-crementó significativamente la AV respecto de la inicial, sin dife-rencias entre grupos. Aunque el seguimiento/tratamiento fue más largo para el grupo mixto, este recibió menos inyecciones antiVE-GF y tomografías de coherencia óptica (OCT). El gasto total por año y ojo tratado fue de 1.972,7 €±824,5; los costes fueron mayores para visita, OCT y tratamiento en el grupo de aflibercept, y menores para angiografías con fluoresceína, tratamiento antiVEGF y costes totales en el grupo mixto. La ganancia decimal de AV tuvo un coste de 872 €±1.077,7 sin diferencias significativas entre grupos.Conclusiones. Los tratamientos antiVEGF con ranibizumab, afli-bercept y ambos mantuvieron la AV en pacientes con DMAE exu-dativa. En general, los costes asistenciales y de tratamiento fueron menores en el grupo que recibió ambos fármacos (AU)

Background. We examined the relationship between visual acuity changes (VA) and the cost of care and treatment with anti-vascular endothelial growth factors (antiVEGF) in patients diagnosed with age-related exudative macular degeneration(exudative AMD).Methods. Observational, longitudinal, retrospective study of pa-tients ≥50 years of age diagnosed with exudative AMD, with a log-MAR VA between 0.6 and 0.06. and 0.06. Follow-up and treatment were done in our tertiary hospital between January 1, 2014 and December 31, 2018.Results. The study included 778 patients; 62.2% female and mean age 79.83±7.94 years; 957 eyes had exudative AMD. Mean of final VA (0.65±0.45) increasing 3.2% compared to initial values. Ranibi-zumab was administered to 60.3% of the eyes, aflibercept to 10.2% and ranibizumab + aflibercept (mixed group) to 29.5%. Significant increase in VA was seen in the group with the mixed treatment, with no inter-group differences. Although follow-up/treatment was longer for the mixed group, they received fewer anti-VEGF injections and optical coherence tomography (OCT). The total expenditure per year and treated eye was €1,972.7±824.5; costs were higher for visit, OCT, and treatment in the aflibercept group, and lower for fluorescein angiography, antiVEGF treatment, and total costs in the mixed group. Decimal VA gain had a cost of €872±1,077.7 with no significant inter-group differences.Conclusion. AntiVEGF treatments (ranibizumab, aflibercept, or both) maintained VA in patients with exudative AMD. Overall, care and treatment costs were lower in the group that received both drugs (AU)

Influence of inflammatory plasma biomarkers on choroidal thickness in type 2 diabetes mellitus.

PURPOSE: To assess the influence of inflammatory plasma biomarkers on choroidal thickness (CT) in patients with type 2 diabetes (T2D). METHODS: Cross-sectional study enrolling T2D patients and age-matched healthy controls (>55 years of age, Caucasian, axial length <26 mm, no macular edema, and naïve). Patients were examined with swept-source OCT Triton, obtaining automatic measurements. CT was analyzed using the ETDRS grid and the recently proposed choroidal division. A blood analysis was commanded: general biochemical profile, liver status, T2D status, thyroid and parathyroid activity, coagulation, general immunological profile, and inflammatory biomarkers. RESULTS: 124 eyes of 124 patients with a mean age between 66 and 68 years were examined. The new choroidal division showed differences between groups (p < 0.05) in more sectors than the ETDRS grid, and more biomarkers influenced these new sectors. T2D patients had higher levels of IL-8, TNF-α, MCP1, adiponectin and L-selectin. CT was influenced by TNF-α, IL-17, leukocytes and erythrocyte sedimentation rate, as well as by HDL cholesterol, albumin, liver function biomarkers, and TSH. HbA1c showed little influence on CT. CONCLUSIONS: T2D patients present increased plasma inflammatory biomarkers, exhibiting an influence on CT. IL-17 is related to a thicker choroid but TNF-α is related to a thinner choroid. HbA1c has little influence on CT. The recently proposed choroidal division is more sensitive to CT changes than the ETDRS grid. Some sectors are more sensitive to plasma biomarkers.

Influence of ocular biometric factors on the defocus curve in an enlarged depth-of-focus intraocular lens.

BACKGROUND: To assess the influence of biometric measurements on the defocus curve after the implantation of enlarged depth-of-focus (EDoF) intraocular lens (IOL). METHODS: Patients who underwent cataract surgery with bilateral implantation of Tecnis Symfony IOL were enrolled. Preoperatively, axial length (AL), corneal keratometry (K), pupil size and corneal aberrations were measured. 1 month after surgery, distance, intermediate, and near visual acuities (VA) were recorded. At 3 months, monocular and binocular corrected contrast sensitivities under photopic and mesopic lighting conditions were measured with CSV-1000E test. At 6-months, the defocus curve between -5.00 to + 3.00 diopters (D) was assessed in steps of 0.50 D, and NEI-RQL-42 questionnaire was administered. RESULTS: One hundred thirty one eyes of 66 patients were included. Binocular logMAR VA better than 0.1 for intermediate vision was obtained in 90% of patients, whereas only 17.7% obtained that result in near vision. The rate of satisfaction was high (96%) and most of them (85.5%) had no or little difficulties in near vision. The mean amplitude of the defocus curve was 2.35D ± 0.73D, and smaller AL, smaller pupils, younger age, and male sex were associated with wider range of clear vision. CONCLUSIONS: Tecnis Symfony IOL enables functional vision at all distances, but demographic variables and preoperative biometric measurements like AL and pupil size influence the postoperative amplitude of the defocus curve. These parameters could be used to predict the performance of EDoF IOLs.

Mapping of choriocapillaris vascular density in young and aged healthy subjects.

PURPOSE: To compare macular vascular density (VD) of the choriocapillaris (CC) between young and aged healthy individuals. METHODS: A cross-sectional study was performed enrolling young and senior healthy individuals of Caucasian race and an axial length (AL) lower than 26 mm, and without systemic or ophthalmological diseases. CC VD was imaged with DRI Triton OCTA using a 6 × 6 mm macular analysis. Internal software delimited CC boundaries and gave colour pictures, which were analysed and codified into numbers, and a grid of 30 × 30 VD values was obtained. Two-dimension (2D) and three-dimension (3D) representations were created. RESULTS: 53 eyes of 53 young healthy individuals and 30 eyes of 30 senior healthy individuals were enrolled. Mean age was 27.17 ± 3.90 years, and 67.00 ± 7.41 years, respectively (p < 0.001). There were no differences in intraocular pressure (IOP) or AL (23.73 ± 0.79 mm, 23.18 ± 0.80 mm, respectively, p = 0.24). There were differences in foveal VD and in temporal perifoveal macula, but not in nasal perifoveal macula. Foveal VD was the highest in both groups. CONCLUSIONS: Foveal CC VD has been found to be considerably high with this method, and it is the area which most decreases with age. Nasal perifoveal VD is not reduced in older individuals. These outcomes are opposite to other studies using different methods but they are in line with previous histological findings.

Ocular related emergencies in Spain during the COVID-19 pandemic, a multicenter study.

PURPOSE: To evaluate ophthalmological emergencies (OE) during the COVID-19 pandemic comparing them with the same period of the previous year. METHODS: Retrospective observational study of all OE visits in four tertiary hospitals in Spain comparing data from March 16th to April 30th, 2020 (COVID-19 period) and the same period of 2019 (pre-COVID-19 period). Severity of the conditions was assessed following Channa et al. publication. Data on demographics, diagnosis and treatments were collected from Electronic Medical Records. RESULTS: During lockdown, OE significantly declined by 75.18%, from 7,730 registered in the pre-COVID-19 period to 1,928 attended during the COVID-19 period (p < 0.001). In 2019, 23.86% of visits were classified as emergent, 59.50% as non-emergent, and 16.65% could not be determined. In 2020, the percentage of emergent visits increased up to 29.77%, non-emergent visits significantly decreased to 52.92% (p < 0.001), and 17.31% of the visits were classified as "could not determine". During the pandemic, people aged between 45 and 65 years old represented the largest attending group (37.89%), compared to 2019, where patients over 65 years were the majority (39.80%). In 2019, most frequent diagnosis was unspecified acute conjunctivitis (11.59%), followed by vitreous degeneration (6.47%), and punctate keratitis (5.86%). During the COVID-19 period, vitreous degeneration was the first cause for consultation (9.28%), followed by unspecified acute conjunctivitis (5.63%) and punctate keratitis (5.85%). CONCLUSIONS: OE visits dropped significantly during the pandemic in Spain (75.18%), although more than half were classified as non-urgent conditions, indicating a lack of understanding of the really emergent ocular pathologies among population.

Sickle cell disease associated with thalassemia; description of a rare mutation.

Sickle cell disease (SCD) is a common hemoglobinopathy, secondary to alterations in the ß globin chain, resulting in an abnormal hemoglobin variant named as hemoglobin S. These disorders show a wide phenotypical spectrum, and the prevalence of these disorders has significantly changed over the time because of multiple factors such as migration. We report a case of a 17-year-old black male, born in Gambia, diagnosed with sickle cell disease, who presented an associated mutation only described in a Japanese family (Oshima et al., 1996).

Comparison of posterior capsule opacification between Clareon CNA0T0 and Tecnis ZCB00 intraocular lenses.

INTRODUCTION: The purpose is to compare posterior capsule opacification (PCO) and its impact on vision between Clareon CNA0T0 (Alcon) and Tecnis ZCB00 intraocular lenses (IOLs) (Johnson&Johnson) 1, 6, and 12 months after implantation. METHODS: A prospective observational study was performed at the Nuestra Señora de Gracia Hospital (Zaragoza, Spain). Fifty eyes (50 patients) with Tecnis IOL (group 1) and 60 eyes (60 patients) with Clareon IOL (group 2) were enrolled. One, 6, and 12 months after age-related cataract surgery by five different surgeons, the following tests were performed: mesopic corrected distance visual acuity (CDVA), CSV1000-E test, KR-1W wavefront analyzer, OQAS II, Catquest-9SF questionnaire and mydriatic slit-lamp pictures. PCO intensity was quantified and the area of opacification was measured using ImageJ (NIH). RESULTS: Mean age was 71.20 ± 6.79 years in group 1, and 71.73 ± 8.17 years in group 2 (p = 0.72); mean axial length was 23.46 ± 1.14 and 23.53 ± 0.91 mm, respectively (p = 0.72); mean IOL power was 21.69 ± 2.26 D and 21.28 ± 2.44 D, respectively (p = 0.37). One month after surgery there were differences in intensity of PCO (0.73 ± 0.60 and 1.05 ± 0.71, respectively, p = 0.02). Six months after surgery statistical differences were found in VA with 20% CS in mydriatic conditions (0.26 ± 0.21 logMAR (20/36) and 0.18 ± 0.17 logMAR (20/30), respectively, p = 0.04). Twelve months after surgery, no differences were detected between groups. As for the evolution of PCO within the Clareon group, high order aberrations (p < 0.05) and the Strehl ratio (p = 0.02) decreased. CONCLUSION: There are no differences in slit-lamp pictures or visual function between both IOLs during the first 12 months after implantation.

Relationship between vascular densities of choriocapillaris and the whole choroid using OCTA.

PURPOSE: To study the vascular density (VD) of choriocapillaris and the whole choroid using optical coherence tomography-angiography (OCTA). METHODS: Cross-sectional study enrolling healthy individuals between 18 and 35 years old and with an axial length (AL) lower than 26 mm, who were examined with swept-source OCTA Triton DRI (Topcon). Color pictures of both VD were obtained from a fovea-centered 6 × 6 mm macular exam, which were divided into 900 squares and codified into numbers. RESULTS: A total of 50 patients (100 eyes) with a mean age of 27.29 ± 3.90 years and a mean AL of 23.67 ± 0.74 mm were analyzed. The highest choroidal VD was found in juxtapapillary macula, being followed by the most temporal macula and fovea. The lowest was found in superior and inferior perifoveal areas. The highest VD in choriocapillaris was in the fovea. VD in this layer was uniform, with a decrease from temporal toward nasal. Both VD differed and but correlated, especially in the fovea and in inferior-temporal macula. CONCLUSION: VD of choriocapillaris and the whole choroid are not similar. The former is maximal in the fovea, and the latter is maximal in the juxtapapillary macula. In general lines, choroidal VD is higher than that of choriocapillaris. Both VD are directly correlated.

Mapping choroidal thickness in patients with type 2 diabetes.

OBJECTIVE: To determine and compare topographic features of the choroidal thickness (CT) between patients with type 2 diabetes (T2D) and age-matched healthy controls based on swept source-optical coherence tomography (SS-OCT). DESIGN: Cross-sectional study. PARTICIPANTS: 96 T2D patients and 33 healthy individuals aged above 18 years and with an axial length (AL) lower than 26 mm were included. METHODS: A macular 6 × 6 mm cube, comprising 900 200 × 200 µm cubes, was scanned with SS-OCT. The choroid was automatically segmented using the segmentation algorithm. Three-dimensional maps were created to represent the choroid. The scanned area was divided into different zones based on CT, and equivalent zones were compared between groups. RESULTS: Mean age (standard deviation) in the control group was 66.83 (7.3) years, and that of the T2D group was 67.94 (7.9) years (p = 0.48). Both groups were similar regarding AL and spherical equivalent. Overall, CT was significantly thinner in the T2D group; it was 203.78 (53.40) in healthy individuals and 169.98 (63.22) in T2D patients (p = 0.01). Outside the fovea, the mean CT was thicker in the superior hemiretina and decreased inferiorly, temporally, and nasally, with minimum thickness in the most distant points from the fovea. CONCLUSIONS: Choroidal thickness follows an ellipsoid pattern in both nondiabetic and diabetic eyes, with diabetic eyes showing thinner measurements diffusely. Understanding these differences is important for future studies aimed at understanding the pathophysiological underpinnings of diabetic retinopathy.

Distribution of Choroidal Thinning in High Myopia, Diabetes Mellitus, and Aging: A Swept-Source OCT Study.

PURPOSE: To compare the macular choroidal thinning between young healthy, aged healthy, young high myopic, and aged type 2 diabetic (T2D) patients using the Early Treatment Diabetic Retinopathy Study (ETDRS) grid and three-dimensional (3D) maps. METHODS: A prospective study including 102 eyes of 51 healthy young subjects, 60 eyes of 30 healthy aged subjects, 24 eyes of 12 high myopic patients, and 110 eyes of 55 T2D patients. Choroidal thickness (CT) was examined with swept-source optical coherence tomography Triton DRI (Topcon Corporation, Tokyo, Japan). The choroid was automatically segmented using the software algorithm, and mean CT values of a 6 × 6 mm macular cube were exported. 3D maps were created to represent CT, and its values were compared using the ETDRS grid. RESULTS: Mean age was 27.31 ± 3.95, 66.41 ± 7.54, 27.69 ± 3.89, and 66.48 ± 7.59 years in young healthy, aged healthy, young high myopic, and T2D patients, respectively. CT was not shown to be uniform, as superior and central zones were thicker. All ETDRS sectors were always thicker (p < 0.05) in young healthy individuals than in the others. It was found that the choroidal sector which got thinner was inferior in case of age (103.28 µm decrease), inferior-nasal in high myopia (86.19 µm decrease), and temporal in T2D (55.57 µm decrease). In addition, the choroid got thinner in those regions where it was thicker in healthy subjects. CONCLUSIONS: 3D maps allow a further comprehension of choroidal changes. The choroidal pattern in young healthy individuals resembles a mountain range; with age, a mountain peak; in high myopia, an inverted gorge; and in aged T2D, gathered hills. Not all choroidal regions are affected in a similar way, as it depends on the pathology. The thicker the zone is in healthy subjects, the thinner it becomes with any pathology.

Reading and quality of life differences between Tecnis ZCB00 monofocal and Tecnis ZMB00 multifocal intraocular lenses.

PURPOSE: To compare the NEI-RQL-42 quality of life questionnaire and the Radner Vissum reading test outcomes after bilateral cataract surgery with implantation of Tecnis ZCB00 monofocal and Tecnis ZMB00 multifocal intraocular lens (IOL). METHODS: Forty-two eyes of 21 patients who had phacoemulsification were implanted with Tecnis ZCB00 IOL and 82 eyes of 41 patients were implanted with Tecnis ZMB00 IOL. They answered the NEI-RQL-42 questionnaire before cataract surgery and 3 months after it. The Radner Vissum test was performed 3 months after the surgery with optical correction for near vision in patients with monofocal IOL, but without it in patients with multifocal IOL. RESULTS: Regarding the NEI-RQL-42 test, the multifocal group obtained better results in items 2, 7, 8, 11, 13, 31, and 40, and in the following categories: near vision, dependence on correction, and suboptimal correction (p<0.05). The monofocal group only showed better results in item 17. As for the Radner Vissum test, the multifocal group obtained significantly better results in phrases 1, 3, 4, and 5, and in the number of incorrect syllables (p<0.05). CONCLUSIONS: Patients with Tecnis ZMB00 multifocal IOL report a higher quality of life regarding the lack of need for optical correction for near vision in their daily activities, but halos in vision at night. Additionally, patients with multifocal IOL achieve similar or better reading quality at near vision and under photopic lighting conditions than patients with monofocal IOL with near vision optical correction.
