Antepartum Rupture of the Posterior Uterine Wall in a Woman With Two Previous Cesarean Deliveries.

Uterine rupture is a rare pregnancy complication. In patients with a previous cesarean delivery, it usually involves the scarred area. Uterine rupture of the posterior wall is even rarer and mostly described during labor. Conditions that confer fragility to the posterior uterine wall have been associated with an increased risk of uterine rupture. There are very few cases of spontaneous posterior uterine wall rupture in a non-labor setting in pregnant women without risk factors. We report the case of a pregnant woman admitted to the hospital due to placental abruption at 26 weeks' gestation. Once fetal and maternal stability were assured, expectant management was maintained. At 29 weeks, an emergent cesarean delivery due to fetal bradycardia was performed, and a large rupture of the posterior uterine wall was diagnosed. Subsequently, a hysterectomy was performed. The patient was discharged nine days after the procedure and the newborn on the 64th day of life.

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.

Validation of a community-based application of the Portuguese version of the survey on Social and Emotional Skills - Child/Youth Form.

Introduction: Children and adolescents' social and emotional skills have been gaining attention in diverse settings. With over 100 conceptual frameworks available, there is now a common move toward framing these skills as social and emotional learning (SEL), assuming that they are not only amiable to development, but also malleable to change as a product of intervention. As such, there is a strong need for a comprehensive measure to effectively evaluate such skills, validated for different age groups in children and young people, and applicable to both educational contexts and community settings. Methods: This paper presents the validation of the Portuguese adaptation of the Child/Youth form of the Survey on Social and Emotional Skills (SSES), in the scope of the Gulbenkian Academies for Knowledge initiative with a sample of 7,831 participants between 8 and 17 years old (M = 11.79, SD = 2.94). Results: Results show that the measure has good internal consistency and sensitivity, while also being sensitive to change over time. Preliminary factor analysis shows promise, although further research is necessary. Discussion: Discussion reflects on the value of the Child/Youth form of the SSES as a comprehensive measure to be used by community and educational professionals to monitor skill development and improve their work on SEL.

Comparison of Light-Based Devices in the Treatment of Meibomian Gland Dysfunction.

PURPOSE: To compare different light-based devices, namely, intense pulsed light (IPL) and IPL with low-level light therapy (LLLT), in the treatment of meibomian gland dysfunction (MGD). METHODS: This was a prospective, observational study that included patients with MGD. Group 1 included 58 eyes treated with IPL (eye-light®, Espansione Marketing S.p.A., Bologna, Italy), followed by LLLT (my-mask®, Espansione Marketing S.p.A., Bologna, Italy); Group 2 included 60 eyes treated with IPL (E>Eye®, E-Swin, Houdan, France); and Group 3 included 58 eyes treated with IPL (Thermaeye Plus®, OptiMed, Sydney, Australia). The presence of symptoms (Ocular Surface Disease Index (OSDI)) and ocular surface changes were evaluated at baseline, three weeks, and six months after treatment. RESULTS: At week three, there was an improvement in the OSDI in all groups (p<0.001), without differences among them (p=0.339). The lipid layer thickness (LLT) increased in Groups 1 and 2 (p<0.001), with a similar variation (p=0.144). Patients with superior OSDI and lower LLT at baseline had the greatest improvement in the respective parameters (p<0.001). The basal tear flow increased in Group 1 (p=0.012). Corneal staining (CS) significantly decreased in Groups 2 (p<0.001) and 3 (p<0.001). At six months, compared to three weeks, there was further improvement in the OSDI (p<0.001) and the LLT (p=0.007), in Group 1, and an increase in the presence of CS in Group 3 (p=0.011). CONCLUSION: IPL treatment led to a sustained decrease in patients' symptoms, even after six months. Different IPL devices seem to have different beneficial effects. Adding LLLT to IPL appears to have an additional long-term beneficial effect as well as positive effects on the lacrimal gland.

Comparison of Color Fundus Photography and Multicolor Fundus Imaging for Detection of Lesions in Diabetic Retinopathy and Retinal Vein Occlusion.

Purpose: To evaluate the agreement between conventional fundus photography (CFP) and multicolor fundus imaging (MFI) for the detection of lesions of diabetic retinopathy (DR) and retinal vein occlusion (RVO). Methods: Cross-sectional analysis of eyes with DR or RVO who underwent CFP and MFI. All images were independently analyzed by two observers (O1 and O2), and the evaluated lesions were classified as "present" or "absent". Then, a paired comparison between both exams of the same eye was performed, to assess which made it easier to detect the lesions. Results: Considering DR, the agreement was substantial for cotton wool spots and photocoagulation scars for both observers (O1: κ=0.75 and κ=0.67; O2: κ=0.71 and κ=0.64, respectively) and for hard exudates for O1 (κ=0.80). These lesions were detected more frequently on MFI. Regarding RVO, the agreement was considered substantial for venous sheathing by O1 (κ=0.64) and moderate for optociliary shunts by O2 (κ=0.60). Optociliary shunts were detected more frequently in CPF by both observers and venous sheathing on MFI by O1. For microaneurysms, retinal hemorrhages, retinal neovascularization, and proliferative membranes, in DR, and retinal hemorrhages, venous engorgement, and retinal neovascularization in RVO, the agreement was almost perfect (κ>0.82). In the paired analysis, both observers considered that, in DR, microaneurysms and retinal hemorrhages were easier to detect on CFP and that retinal neovascularization, cotton wool spots, and photocoagulation scars were easier to identify on MFI. Regarding RVO, optocilliary shunts were easier to identify on CFP and venous engorgement on MFI. Conclusion: The agreement of MFI and CFP was substantial to almost perfect for most lesions. MFI seems better to detect cotton wool spots and photocoagulations scars in DR and venous sheathing in RVO. Optocilliary shunts seem easier to detect on CFP.

Ocular Surface Changes in Primary Open Angle Glaucoma Patients Treated With Topical Antihypertensive Drugs.

PRCIS: In this study, patients with glaucoma undergoing topical antihypertensive (TAH) drugs had changes in the ocular surface and more dry eye symptoms than controls. Clinicians should recognize the influence of TAH drops on exacerbating ocular surface disease. PURPOSE: The purpose of this study was to evaluate the ocular surface of eyes with glaucoma treated with TAH drugs. METHODS: Cross-sectional study that included eyes undergoing TAH drugs due to primary open angle glaucoma and controls. The parameters evaluated were: the basal tear flow (basic secretion test); the tear film osmolarity (TearLab); and the noninvasive break-up time, blink score, lipid layer thickness, tear meniscus height, and loss area of the meibomian glands, measured with the IDRA Ocular Surface Analyser. Presence of symptoms [Ocular Surface Disease Index (OSDI)], dry eye disease (DED, TFOS DEWS II criteria), and corneal fluorescein staining were assessed. RESULTS: We included 154 eyes (154 patients), 77 undergoing TAH drugs for glaucoma (group 1) and 77 of controls (group 2). The tear film osmolarity ( P =0.003) and the loss area of the meibomian glands ( P =0.004) were higher in group 1. The noninvasive break-up time ( P =0.005), lipid layer thickness ( P =0.006), and tear meniscus height ( P =0.001) were lower in group 1. The global OSDI score ( P <0.001), the proportion of eyes with severe disease ( P =0.002), according to the OSDI, and with DED ( P <0.001), according to the TFOS DEWS II criteria, were higher in group 1. The proportion of patients with corneal fluorescein staining was higher in group 1 ( P <0.001). There were no significant differences in eyes taking TAH drugs with and without preservatives ( P >0.127). CONCLUSIONS: DED, in patients with glaucoma, is a multifactorial disease, with a strong contribution from TAH drugs. These eyes had changes in almost every measured parameter, translating into the presence of more dry eye symptoms and corneal damage when compared with controls.

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.

PARACENTRAL ACUTE MIDDLE MACULOPATHY AFTER COVID-19: MULTIMODAL EVALUATION.

PURPOSE: To report the case and multimodal imaging findings of a healthy young woman who developed paracentral acute middle maculopathy 9 weeks after COVID-19. METHODS: Case report. Ultra-widefield fundus photography, macular spectral domain optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography were performed. RESULTS: A 36-year-old woman went to the emergency department with sudden, painless, left eye vision loss. The only relevant medical history was COVID-19 9 weeks before. The best-corrected visual acuity was 20/200, a left eye relative afferent pupillary defect was present, and superficial hemorrhages throughout the macular area and peripheral retina were found. Nearly 4 hours after admission, the left eye best-corrected visual acuity recovered to 20/20 without relative afferent pupillary defect. Five days after presentation in the emergency department, the patient returned with recurrent left eye vision loss, with spontaneous recovery within 12 hours. Macular spectral domain optical coherence tomography revealed hyperreflectivity of the inner plexiform and inner nuclear layers, and the diagnosis of paracentral acute middle maculopathy was established. The patient started oral acetylsalicylic acid and oral prednisolone. The patient did not report any new episodes of vision loss, and there was a progressive resolution of abnormal fundus findings. CONCLUSION: SARS-CoV-2 infection increases the risk of vascular thrombotic events with possible involvement of the retinal circulation, and paracentral acute middle maculopathy may present as a possible complication. Ophthalmologists should be able to recognize it promptly through multimodal imaging findings.

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.

Size does matter: intraspecific geometric morphometric analysis of wings of the blowfly Chrysomya albiceps (Diptera: Calliphoridae).

Blowflies have forensic, sanitary and veterinary importance, as well as being pollinators, parasitoids and ecological bioindicators. There is still little work with real data and from experiments assessing the relationship between blowflies' morphologic features and environmental and demographic factors. The present work tests whether the variation, in the shape and size, of Chrysomya albiceps (Wiedemann, 1819) wings is influenced by the following factors: 1) time; 2) temperature; 3) sex and; 4) different types of carcasses (pig, dog/cat and whale). Male and female wings from four different sites collected in six different years were used to obtain wing size and shape of C. albiceps. Analyses between wing shape and the variables tested had low explanatory power, even though they had statistical support. However, it was possible to identify differences in wing shape between males and females, with good returns in sex identification. The comparison between wing size and the variables tested showed that wing size has a negative relationship with temperature, significant differences between sexes, slight variation over time and no influence by carcass types. Furthermore, wing size influenced wing shape. Understanding population-specific characteristics of C. albiceps provide important insights about how the species reacts under specific conditions.

Perceptions of Sexual Abuse in Sport: A Qualitative Study in the Portuguese Sports Community.

Child sexual abuse is a complex issue that can take place in different contexts. Sports settings have specific features which pose increased risk for sexual abuse to occur. Recently, a country-specific roadmap for effective child safeguarding in sport was launched. Considering the need to achieve a comprehensive picture of violence against children in sports settings in Portugal, we analyzed the perceptions of the sports community in Portugal regarding child sexual abuse, its victims and perpetrators, and the specific risk factors in sports settings, as studies about this specific topic are scarce at the national level. A descriptive exploratory study was conducted using an online questionnaire with open-ended questions. Three hundred participants, i.e., sports managers, coaches, and athletes over 18 years of age (M = 33.13; SD = 13.062), of which 55.7% were female, answered. A thematic analysis of these data was conducted using NVivo software. Inter-rater agreement was strong for almost all variables. Results indicated that sexual abuse is perceived as being associated with physical and emotional abusive behaviors for which there is no consent from the victim, in a relationship that is guided by a relationship with power imbalances. Victims were mainly perceived as being female children, and perpetrators as adult males in a powerful position over the victim. As to possible signs of sexual abuse victimization, results showed that the participants identify behaviors, such as isolation, and physical evidence, such as marks and injuries. Risk factors specific to sports setting included the physical contact involved in many modalities, as well as the close and trustful relationship established between coach and athlete. Results are in line with previous studies showing that coaches, athletes, and sports managers share a common understanding of sexual abuse, although not always accurate. These results shed light on important practical and policy implications relevant to country-specific sport policies for effectively safeguarding children.

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.

Choroidal changes and associations with visual acuity in diabetic patients.

BACKGROUND: The variable visual function observed in diabetic retinopathy (DR) patients is not fully explained by the classic staging system. Our purpose was to evaluate choroidal changes, in standardized sectors, in DR patients and to find associations between choroidal measurements and visual function. METHODS: Cross-sectional study that included the right eye of diabetic patients (n = 265) without active edema, ischemia or neovascularization and age-matched controls (n = 73). Optical coherence tomography (OCT) imaging was performed with enhanced depth imaging protocol. Choroidal vascularity index (CVI) was calculated in a 5 mm scan centered in the fovea. RESULTS: CVI decreased with age (p < 0.001) but was not influenced by axial length. A multivariate analysis adjusting for age confirmed a significant difference in CVI between DR eyes that had previous treatments (intravitreal injections and/or photocoagulation) compared to control eyes (p = 0.013) and to DR eyes that never required treatment (p = 0.002). There was no significant difference between non-DR diabetic patients and normal controls. Considering the group of DR patients that had previous treatments, in eyes without optic media opacification, BCVA correlated with CVI (r = - 0.362, p < 0.001), whereas full retina thickness and individual retinal layer thickness did not (p > 0.066). CONCLUSIONS: A reduction in CVI was observed in patients with a more advanced stage of DR. In treated DR patients with stable disease, choroidal biomarkers correlated with best-corrected visual acuity whereas retinal biomarkers did not. TRIAL REGISTRATION: N/A.

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.

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.

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.

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 %.
