Long-Term Refractive Outcomes and Visual Quality of Multifocal Intraocular Lenses Implantation in High Myopic Patients: A Multimodal Evaluation.

Purpose: To perform a multimodal assessment of refractive outcomes and quality of vision (QoV) in patients with high myopia submitted to multifocal intraocular lens (IOL) implantation. Methods: Retrospective study that included consecutive eyes with high myopia (axial length [AL] >26.00mm) submitted to multifocal IOL implantation between January 2014 and February 2020. Minimum follow-up time was 3 years. QoV was evaluated with the Objective Scatter Index (OSI) and the Modular Transfer Function (MTF) by HD Analyzer®. Two QoV questionnaires were applied to patients in which both eyes were included: the McAlinden and the Catquest-9 SF. Results: We included 50 eyes (28 patients). The mean follow-up time was 5.4±1.0 years. Comparing to month 1 after surgery, at the last follow-up visit, there was a decrease in the uncorrected visual acuity (0.14±0.13 vs 0.08±0.09 LogMAR, p=0.024), a negative increase in the spherical equivalent (-0.31±0.60 vs -0.02±0.20, p=0.006) and no changes in the best-corrected visual acuity (p>0.999). An uncorrected near visual acuity of at least J2 was achieved in 89% of eyes one month after surgery and in 91% of eyes at the last follow-up visit (p=0.829). At the last follow-up, the mean OSI was 5.1±1.8 and the mean MTF was 17.5±10.6. Some degree of near vision difficulty was reported by 91% of patients, and 74% of patients reported photic phenomena (halos, glare, starbursts). However, most patients reported that these symptoms caused none to little bothersome. At the last follow-up, 87% of patients were at least fairly satisfied with the surgery. Conclusion: Even after a mean follow-up time of 5 years, patients maintained good uncorrected visual acuity. Even though most patients experienced some degree of near vision difficulty and visual symptoms, globally, our patients were satisfied with their current vision, and the experienced symptoms did not have a significant impact on their daily lives.

Retinal changes after fluocinolone acetonide implant (ILUVIEN®) for DME: SD-OCT imaging assessment using ESASO classification.

INTRODUCTION: A detailed understanding of the anatomical and structural changes occurring in the retina following intravitreal fluocinolone acetonide implantation may help improve the management and prognosis of persistent or recurrent diabetic macular edema (DME). METHODS: Overall, 45 eyes (from 35 patients) with refractory center-involved DME received an intravitreal fluocinolone acetonide implant. They were monitored at baseline and at 6, 12, 24, and 36 months for best-corrected visual acuity (BCVA), central foveal thickness (CFT), and the seven retinal parameters used in the classification of diabetic maculopathy recently developed at the European School for Advanced Studies in Ophthalmology (ESASO). RESULTS: Within 6 months of implantation, significant improvements were evident in BCVA, CFT, maculopathy stage, and the percentage of eyes with: intraretinal cysts; CFT > 30% above the upper normal value; and disrupted or absent ellipsoid zone (EZ) and/or external limiting membrane (ELM). Significant improvements were still maintained at 36 months post-implantation. At month 36, early treatment with the implant (i.e., after < 6 previous intravitreal injections for DME) trended toward being more effective than later treatment in improving BCVA, CFT, maculopathy stage, and the percentage of eyes with CFT > 30% above the upper normal value. However, statistical significance was not achieved. CONCLUSION: In persistent or recurrent DME, fluocinolone acetonide implantation can be effective in improving maculopathy stage and reducing the percentage of eyes with: intraretinal cysts; CFT > 30% above the upper normal value; and disrupted or absent EZ and/or ELM. It can also increase BCVA and reduce CFT.

Refractive Management of Surgical-Induced Presbyopia in a Young Patient with Vision-Related Quality of Life Complaints: A Case Report.

Visual difficulties can negatively impact life quality. Our purpose was to report the refractive surgical planning and outcomes of a young patient with mixed astigmatism and phacoemulsification-induced presbyopia due to congenital cataracts who was unsatisfied with her vision-related quality of life. A 32-year-old woman, submitted to phacoemulsification with implantation of a monofocal intraocular lens (IOL) and Nd:YAG laser posterior capsulotomy 3 years before, due to congenital cataracts, was referred to the Refractive Surgery Unit of Centro Hospitalar Universitário de Santo António. She had mixed astigmatism (+1.00-4.00 × 10° in the right eye [RE] and +0.50-1.75 × 180° in the left eye [LE]) and surgical-induced presbyopia, was intolerant to contact lenses, and felt that her vision significantly impaired her life quality. A trifocal Sulcoflex® (Rayner) IOL was implanted to correct the spherical and near refractive errors. In a second surgical time, a photorefractive keratectomy was performed to correct the residual astigmatism (-3.50 × 10° in the RE and -1.50 × 170° in the LE). In the last visit, distance and near uncorrected visual acuity were 20/20 (Snellen) and Jaeger 1, respectively, in both eyes, and the patient was very satisfied. When assessing the surgical options of young, working-age patients, clinicians should, when possible, consider alternative solutions to monofocal IOLs. In this patient, the combination of corneal and intraocular procedures allowed the correction of both the distance and near refractive errors, with a subsequent significant improvement in the patient's quality of life.

Descemet Stripping Without Endothelial Keratoplasty in Early-Stage Central Fuchs Endothelial Dystrophy: Long-term Results.

PURPOSE: The purpose of this study was to report long-term results of Descemet stripping without endothelial keratoplasty (DWEK) associated with phacoemulsification in patients with early-stage central Fuchs endothelial corneal dystrophy. METHODS: This is a retrospective study, including all patients submitted to DWEK associated with cataract surgery with a minimum follow-up of 24 months. Included patients had central confluent guttae confirmed with specular microscopy, a clear peripheral endothelium (with a peripheral endothelial count >1500 cells/mm 2 ), and a central pachymetry <600 µm. The main end points were the presence of a clear cornea and time that was needed to achieve transparency, best-corrected visual acuity in logMAR, endothelial central cell count (ECC), and central pachymetry. RESULTS: A total of 22 eyes were included with a mean follow-up of 40.8 ± 10.5 months. At baseline, mean central pachymetry was 536 ± 34 mm and 6 eyes had countable ECC (mean 1138 ± 190 cells/mm 2 ). Twenty eyes (90.9%) achieved good corneal transparency 3.2 ± 1.1 months after surgery. There was a significant improvement in logMAR best-corrected visual acuity compared with baseline (0.13 ± 0.10 vs. 0.48 ± 0.24, respectively, P < 0.001). Endothelial central repopulation was observed in all successful cases. Twelve months after DWEK, ECC was 1449 ± 344 cells/mm 2 and 1393 ± 450 cells/mm 2 at the end of follow-up, without a significant decrease between this period ( P = 0.081). Only 2 eyes (9.1%) did not achieve corneal transparency and were submitted to an endothelial keratoplasty. CONCLUSIONS: According to our results, DWEK is a safe and effective procedure in selected cases of early-stage central Fuchs endothelial corneal dystrophy. This seems to be a promising technique, delaying or avoiding endothelial transplantation.

Posterior Capsular Rupture during Cataract Surgery in Eyes Previously Treated with Intravitreal Injections.

INTRODUCTION: Intravitreal injections (IVIs) are currently the most common intraocular surgical procedure worldwide. Some studies have reported a higher risk of intraoperative complications, namely, posterior capsular rupture (PCR), during cataract surgery. The aim of this retrospective and observational study, conducted at Department of Ophthalmology, Centro Hospitalar Universitário do Porto, was to assess the risk of PCR during cataract surgery in eyes previously treated with IVIs with anti-vascular endothelial growth factor (anti-VEGF) and/or corticosteroids. METHODS: Eyes undergoing cataract surgery between June 2019 and May 2021 were included. Combined surgeries, such as glaucoma surgery and pars plana vitrectomy, were excluded. The occurrence of PCR during cataract surgery in treated and previously untreated eyes with IVI was analyzed. RESULTS: A total of 5,813 cataract surgeries were analyzed; 4.1% of the cases had previously undergone IVI. The PCR rate in cataract surgery was 1.8%: 6.7% in eyes previously treated with IVI and 1.6% without previous IVI (OR = 4.5, 95% CI: 2.6-7.7, p < 0.001). The combined therapy (anti-VEGF with corticosteroids) presents a higher risk compared to the two therapies alone as monotherapy (OR = 11.6, 95% CI: 4.7-28.5, p < 0.001), as well as treated eyes treated with ≥10 IVI (OR = 2.1, 95% CI: 0.8-6.1, p = 0.144) and a time interval between the last IVI and cataract surgery was ≤6 months (OR = 1.9, 95% CI: 0.6-6.1, p = 0.296). CONCLUSION: These results demonstrate that eyes that require IV treatment prior to cataract surgery are at increased risk of CPA during cataract surgery, and careful assessment of the characteristics of the cataract and posterior capsule is critical.

Evaluation of Functional Vision and Eye-Related Quality of Life in Children with Strabismus.

Background: Understanding how strabismus impacts a child's quality of life, as well as their families, should be an important key to guide treatment, not only from the ophthalmological point of view but also regarding psychological and social aspects, which are fundamental for a healthy and harmonious development. Methods: A cross-sectional study was performed to evaluate the functional vision and eye-related quality of life (ER-QOL) in a population of children with strabismus submitted or not to corrective surgery, using the recently developed Pediatric Eye Questionnaire (PedEyeQ) and to compare with age and gender-matched visually normal children. The PedEyeQ was applied to non-operated children with strabismus (n = 18), operated children with strabismus (n = 24), and visually normal children (n = 21). This instrument is composed of 3 components (Child, Proxy, and Parent) and has different versions according to the child's age (0-4, 5-11, or 12-17 years-old versions). Clinical data such as age, type of strabismus, angle of deviation, amblyopia, occlusion treatment, and surgical outcome were also recorded. Results: All PedEyeQ domain scores were significantly lower in children with strabismus compared with visually normal children, except the Child "functional vision" domain. Children with strabismus with successful corrective surgery had significantly lower scores in many domains of the Child, Proxy, and Parent components, compared with visually normal children. Conclusion: This study showed that strabismus has an important impact on affected children and their families, as assessed by PedEyeQ. Interestingly, children with prior successful corrective strabismus surgery had worse PedEyeQ scores compared to visually normal children. Educational programs and psychosocial rehabilitation interventions should be implemented in children with strabismus and their families.

Changes in Ganglion Cell Layer Thickness after Treatment with the 0.2 µg/day Fluocinolone Acetonide Implant in Vitrectomized and Nonvitrectomized Eyes with Diabetic Macular Edema.

INTRODUCTION: The objective of this study is to compare changes in ganglion cell layer (GCL) between vitrectomized and nonvitrectomized eyes with diabetic macular edema (DME) over a 2-year period following treatment with 0.2 µg/day fluocinolone acetonide (FAc) implant. METHODS: Eighteen vitrectomized (group 1) and 8 nonvitrectomized (group 2) eyes were included in this cohort study. Changes in central macula GCL thickness were measured using the Spectralis spectral domain-optical coherence tomography at baseline and 6, 12, and 24 months of follow-up. Other parameters analyzed included best-corrected visual acuity (BCVA), central foveal thickness (CFT), and intraocular pressure (IOP). RESULTS: Treatment with the FAc implant led to small reductions in mean global GCL thickness versus baseline and contrasts with the control group that was stable or slightly increased versus baseline. FAc therapy also led to improvements in mean BCVA and CFT that were observed at Month 6 and maintained to Month 24. For vitrectomized and nonvitrectomized eyes, no differences were observed between mean global GCL, BCVA, and CFT values during follow-up. Linear correlations revealed that in all groups mean BCVA at Month 24 positively correlated with mean GCL thickness at baseline and at Month 24. IOP remained stable throughout the 24 months. CONCLUSION: There was no evident retinal neurodegeneration in the 2-year period following treatment with FAc in both groups. GCL thickness may be a useful biomarker for assessing safety and effectiveness in patients with DME.

Dealing with rhegmatogenous retinal detachment in patients under 40 years old: a tertiary center results.

PURPOSE: The risk of rhegmatogenous retinal detachment (RRD) increases with age, but some studies report a secondary peak in younger patients. Since visual recovery in RRD depends on surgical treatment and, considering the personal, social and economic burden of low vision in the working-age population, our purpose was to analyze the features and outcomes of RRD in young patients. METHODS: Clinical data of patients under 40 years old submitted to surgery for first time RRD, consecutively selected between 2016 and 2019, was analyzed. Patients with less than 3 months follow-up were excluded. RESULTS: Eighty-nine eyes from 89 patients were included. Mean age was 31.2 ± 7.8 years (minimum 10 years) and 56% were female gender. Most patients (63%) had high myopia. Pars plana vitrectomy (79%) alone, combined with scleral buckling (1%) or scleral buckling alone (20%) was performed. Primary anatomical success was 72%, and final anatomical success was 91%. Final visual acuity of 20/40 or better was achieved in 29% of cases, but 28% remained under 20/400. The presence of myopia (p = 0.022), localized RRD (p = 0.007) and attached macula at presentation (p < 0.001) was associated with a better final visual acuity. CONCLUSION: Management of RRD in young patients must be thorough. In younger patients, anatomical outcomes may be worse than in older patients. Myopia may be recognized as a major risk factor for RRD in this age group, but also as a protective factor for retinal function after surgery.

Return of phacoemulsification after emergency status related to COVID-19: experience of a tertiary referral center.

PURPOSE: To present a protocol of priority criteria for phacoemulsification after the backlog due to severe acute respiratory syndrome coronavirus (SARS-CoV)-2 pandemic status. SETTING: Ophthalmology department of Centro Hospitalar e Universitário do Porto (CHUP), Oporto, Portugal. DESIGN: Cross-sectional, nonrandomized, retrospective study. METHODOLOGY: Data of all patients waiting for cataract surgery were analyzed at the beginning of May 2020, after 2 months without performing elective surgery. The waiting time since surgical inscription was considered an independent and overriding factor. In addition, higher priority was given to patients with white or brunescent cataracts and patients with low visual acuity: corrected distance visual acuity (CDVA) of 20/200 or less in binocular patients or CDVA of 20/63 or less in monocular patients. Criteria of medium priority included patients who remained with anisometropia and patients with glaucoma or low to moderate risk for chronic angle closure. Data of scheduled surgeries in the following months were then analyzed. RESULTS: A total of 717 patients were waiting for phacoemulsification. One hundred ninety-one patients (26.64%) were on the waiting list more than 4.5 months; the medium waiting time was 3.51 ± 1.57 months. According to both priority criteria and waiting time, 348 (48.6%) were categorized as priority cases. A total of 158 patients (22.0%) met the highest priority; 61 patients (8.5%) met the medium priority criteria. In 129 patients (18.0%), priority was considered based solely on higher waiting time. This algorithm allowed surgeons to operate on all priority cases within the first 3 months. CONCLUSIONS: The presented protocol showed to be effective, providing a timely surgical opportunity for priority cases.

Logistics reorganization and management of the ambulatory pharmacy of a local health unit in Portugal.

The Hospital Pharmacy of a Local Health Unit (LHU) in greater Oporto plays a major role in the community. In addition to providing medicines to the entire Internal Unit, it has created a service called "Hospital Ambulatory Pharmacy", which allows continued hospital treatments at home, in a more comfortable and familiar environment. This is mostly due uderfunding which has hindered recruitment of health professionals as well a growing concern for the comfort of patients as they convalesce. The Hospital Ambulatory Pharmacy's main problems are both recurring stock-outs and over-stocks; the fact that medicines's delivery routes are not completed, and that medical staff lacks awareness of the techniques to overcome the logistic issues involved. As a methodology, a context analysis was carried out, KPI's were created to quantify the problems and raise health professionals' awareness of what was happening. Solutions for storage were analysed and visits were made to a central hospital to analyse the solutions adopted to solve the same problems. The most appropriate inventory management policies were considered for the organization of existing and further resources. We chose to create an Advanced Warehouse with Level Replenishment. The levels were defined considering the demand of each medicine and divided into three different classes to use the best strategy for each type of demand. Then, and with the help of the LHU IT team, the inventory management module of the information system was parameterized, so stock replenishment could be done electronically. All these changes resulted in a 30 % reduction in stock-out. At the beginning of the study, stock-outs would reach peaks of 6 %. These were reduced to 4.5 % at a point at which professionals were already more aware of the logistic problem, and finally to 1.5 %, in the final phase, at a time when the proposal had already been implemented. Over-stock was reduced by 66 %. Delivery routes were stipulated, and compliance was verified. A novel service developed to increase the well-being of patients monitored at home which it is intended to improve the service provided to the users and at the same time reduce operational costs. As a contribution to the knowledge, in addition to the case study presented to be a novelty in terms of scientific articles published because it is a service implemented in the distribution of medications to patients at home, mostly with oncologic diseases. Several methods from Lean Thinking were used, such as, Kanban System and Advanced Warehouse for inventory management levelling and optimization techniques, as well as, operational KPIs, with the purpose to reach out the improvement of program planning and evaluation. This approach resulted in some improvements, namely, the increase of the quality of the healthcare services for the population. And, in terms to reduce stock and excess stock-outs, to reduce inventory costs, setting the delivery routes, raising the entire medical team's awareness of the problem and committing to optimization a reality.

Incontinence surgery in obese women: comparative analysis of short- and long-term outcomes with a transobturator sling.

INTRODUCTION AND HYPOTHESIS: Midurethral slings (MUS) are still discussed in complex incontinence situations, such as obesity, lacking sustained efficacy validation in this particular sub-population. We hypothesized that the outcomes of a transobturator MUS, such as TVT-O, do not differ according to body mass index (BMI) over a 4-year period. METHODS: We conducted a retrospective analysis of 281 women who underwent TVT-O at our institution, between 2004 and 2012. Patients were stratified into obese (BMI ≥ 30 kg/m(2)) or non-obese (BMI < 30 kg/m(2)). We compared preoperative and postoperative parameters, including objective cure (negative stress test), complications, and quality of life scores. Data were collected at 0, 6, 12, 24, and 48 months. We used Fisher's exact test for categorical variables and Student's t test or the Mann-Whitney U test for continuous variables. RESULTS: Baseline characteristics of the obese (n = 122) and non-obese groups (n = 159) were similar. We found no significant differences between groups in terms of objective cure rates at all follow-up evaluations, with 95.8 % and 95 % at 48 months in the non-obese and obese groups respectively. There were no significant differences in the cumulative complication rates of both groups. Quality of life assessment also showed no significant differences between groups at all follow-up visits. At 48 months our follow-up rate was 59 % (n = 96) and 60.4 % (n = 72) in the non-obese and obese group respectively (p = 0.9). CONCLUSIONS: The TVT-O procedure is effective and safe in the long term for stress incontinence treatment, regardless of BMI.

Dois pares de irmãos com artrite idiopática juvenil (AIJ): relato de casos / Two pairs of brothers with juvenile idiopathic arthritis (JIA): case reports

Relato de casos de ocorrência de Artrite Idiopática Juvenil (AIJ) em dois pares de irmãos acompanhados no serviço de reumatologia pediátrica da Universidade Federal da Bahia. O envolvimento genético na patogênese da AIJ está claro e o risco de recorrência entre irmãos corrobora esta contribuição. Um importante marco dessa descoberta envolve a confirmação da contribuição dos polimorfismos do complexo principal de histocompatibilidade (MHC) na susceptibilidade ao desenvolvimento da AIJ. Apesar de muitos progressos, os inúmeros estudos existentes ainda não são capazes de explicar diversos mecanismos implícitos na patogênese da AIJ.

This is a case report of juvenile idiopathic arthritis in two pairs of brothers followed in the Department of Pediatric Rheumatology, Universidade Federal da Bahia. Genetic involvement in juvenile idiopathic arthritis pathogenesis is clear and the risk of recurrence among siblings supports this contribution. An important landmark of this discovery involves the acknowledgment of major histocompatibility complex polymorphism contribution to juvenile idiopathic arthritis development susceptibility. Despite many advances, the numerousavailable studies cannot explain several implicit mechanisms in juvenile idiopathic arthritispathogenesis yet.

The role of fibrin E on the modulation of endothelial progenitors adhesion, differentiation and angiogenic growth factor production and the promotion of wound healing.

Severe skin loss constitutes a major unsolved clinical problem worldwide. For this reason, in the last decades there has been a major push towards the development of novel therapeutic approaches to enhance skin wound healing. Neo-vessel formation through angiogenesis is a critical step during the wound healing process. Besides the contribution of pre-existing endothelial cells (EC), endothelial progenitor cells (EPCs) have also been implicated in wound healing acting either by differentiating into EC that incorporate the neo-vessels, or via the production of paracrine factors that improve angiogenesis. Here we tested the importance of different extracellular matrices (ECM) in regulating the angiogenic and wound healing potential of cord blood-derived EPC (CB-EPC). We compared the properties of several ECM and particularly of fibrin fragment E (FbnE) in regulating EPC adhesion, proliferation, differentiation and healing-promotion in vitro and in vivo. Our results show that CB-EPCs have increased adhesion and endothelial differentiation when plated on FbnE compared to collagens, fibronectin or fibrin. Using integrin neutralizing antibodies, we show that CB-EPC adhesion to FbnE is mediated by integrin α5ß1. Gene expression analysis of CB-EPCs plated on different substrates revealed that CB-EPC grown on FbnE shows increased expression of paracrine factors such as VEGF-A, TGF-ß1, SDF-1, IL-8 and MIP-1α. Accordingly, conditioned media from CB-EPC grown on FbnE induced EC tube formation and monocyte migration in vitro. To test the wound healing effects of FbnE in vivo we used an FbnE enriched scaffold in a cutaneous wound healing mouse model. In accordance with our in vitro data, co-administration of the FbnE enriched scaffold with CB-EPC significantly accelerated wound closure and wound vascularization, compared FbnE enriched scaffold alone or to using collagen-based scaffolds. Our results show that FbnE modulates several CB-EPC properties in vivo and in vitro, and as such promotes wound healing. We suggest the use of FbnE-based scaffolds represents a promising approach to resolve wound healing complications arising from different pathologies.
