The efficacy of adjunctive mitomycin C and/or anti-VEGF agents on glaucoma tube shunt drainage device surgeries: a systematic review.

PURPOSE: The effectiveness of mitomycin C (MMC) in trabeculectomy has long been established. The aim of this review is to evaluate the efficacy and safety of adjunctive agents in tube shunt drainage device surgery for glaucoma or ocular hypertension, since controversy still exists regarding their benefit. METHODS: We searched CENTRAL, PubMed, Embase, Web of Science, Scopus, and BASE for RCTs, which have used adjuvant antimetabolites-either MMC or 5-Fluorouracil (5-FU)-and/or anti-vascular endothelial growth factors (anti-VEGF) agents. The main outcome was IOP reduction at 12 months. RESULTS: Ten studies met our inclusion criteria. Nine used the Ahmed Glaucoma Valve (AGV) implant, while the double-plate Molteno implant was used in one study. Four studies used MMC. The remaining six studies used an anti-VEGF drug - either bevacizumab, ranibizumab or conbercept. Only one MMC-study reported a significant difference in the IOP reduction between groups at 12 months, favouring the MMC group (55% and 51%; p < 0.01). A significant difference was also reported by two out of five bevacizumab-studies, both favouring the bevacizumab group (55% and 51%, p < 0.05; 58% and 27%, p < 0.05), with the highest benefit seen in neovascular glaucoma cases, especially when panretinal photocoagulation (PRP) was also used. Neither ranibizumab nor conbercept were found to produce significant differences between groups regarding IOP reduction. CONCLUSION: There is no high-quality evidence to support the use of MMC in tube shunt surgery. As for anti-VEGF agents, specifically bevacizumab, significant benefit seems to exist in neovascular glaucoma patients, especially if combined with PRP.

Outcomes of minimally invasive isolated tricuspid valve repair and replacement through right mini-thoracotomy.

Objective: Isolated tricuspid valve surgery is uncommon and associated with high perioperative morbidity and mortality. We aimed to study the overall outcomes of patients who underwent minimally invasive right thoracotomy tricuspid valve surgery (Mini-TVS), consisting of either tricuspid valve repair (TVre) or replacement (TVR). Methods: We performed a retrospective analysis of all Mini-TVS procedures (2017-2022), through which we identified isolated tricuspid valve surgeries. We examined in-hospital outcomes, survival analysis over a 4-year period, and competing risk analysis for reoperative surgery. Results: Among a total of 51 patients, the average age was 60 ± 16 years, and 67% (n = 34) were female. Severe tricuspid regurgitation was present in all cases. Infective endocarditis was noted in 7.8% (n = 4), and 24% (n = 12) had preexisting pacemakers. Mini-TVS included TVre in 18 patients (35%) and TVR in 33 patients (65%). The in-hospital and 30-day mortality rates were 4% (n = 2) and 6% (n = 3), respectively. At 4 years, the overall TVS survival was 76% (confidence interval, 62-93%), with no significant difference between TVre and TVR (91% vs 69%, P = .16). At follow-up, 3 patients required repeat surgery for recurrent regurgitation after 2.6, 3.3, and 11 months, with a reoperation rate of 7.3% (confidence interval, 2.4-22%) at 2 years. Factors associated with worse overall survival included nonelective surgery, right ventricular dysfunction, serum creatinine >2 g/dL, and concomitant left-sided valve disease. Conclusions: A nonsternotomy minimally invasive approach is a feasible option for high-risk patients. Midterm outcomes were similar in repair or replacement. Patients with right ventricular dysfunction and left-sided disease had worse outcomes.

Differentiating Ischemic Optic Neuropathy from Glaucoma Using Diagnostic Tests.

INTRODUCTION: Anterior ischemic optic neuropathy (AION) can mimic glaucoma and consequently cause difficulties in differential diagnosis. The purpose of this paper was to summarize differences in diagnostic tests that can help perform a correct diagnosis. METHODS: The search strategy was performed according to the PRISMA 2009 guidelines, and four databases were used: MEDLINE, Embase, Web of Science, and Cochrane. Totally, 772 references were eligible; 39 were included after screening with respect to inclusion criteria that included English language and published in the 20 years before search date. RESULTS: Ninety percent (n = 35) of included studies used optical coherence tomography (OCT). Glaucomatous eyes had a significantly greater cup area, volume and depth, cup-to-disk ratio, a lower rim volume and area, and a thinner Bruch's membrane opening-minimum rim width. Retinal nerve fiber layer (RNFL) thinning in glaucomatous eyes occurred primarily at the superotemporal, inferotemporal, and inferonasal sectors, while AION eyes demonstrated mostly superonasal thinning. Glaucoma eyes showed greater macular ganglion cell layer thickness, except at the inferotemporal sector. OCT angiography measurements demonstrated a significant decrease in superficial and deep macular vessel density (VD) in glaucoma compared to AION with similar degree of visual field damage; the parapapillary choroidal VD was spared in AION eyes compared to glaucomatous eyes. CONCLUSION: By use of OCT imaging, optic nerve head parameters seem most informative to distinguish between glaucoma and AION. Although both diseases affect the RNFL thickness, it seems to do so in different sectors. Differences in structure and vascularity of the macula can also help in making the differential diagnosis.

Nationwide consensus on quality indicators to assess glaucoma care: A modified Delphi approach.

PURPOSE: Performance assessments are essential to tracking and improving quality in health care systems. Key aspects of the care process that act as indicators must be measured in order to gain an in-depth understanding of a care unit's operation. Without standardized quality indicators (QIs), it is difficult to characterize and compare the abilities of institutions to achieve excellence. The aim of this study is to reach a consensus among glaucoma specialists concerning the development of a set of QIs to assess the performance of glaucoma care units. METHODS: A two-round Delphi technique was performed among glaucoma specialists in Portugal, using a 7-point Likert scale. Fifty-three initial statements (comprising process, structure, and outcome indicators) were evaluated and participants had to agree on which ones would be part of the final set of QIs. RESULTS: By the end of both rounds, 28 glaucoma specialists reached consensus on 30/53 (57%) statements, including 19 (63%) process indicators (mainly relating to the proper implementation of complementary exams and the setting of follow-up intervals), 6 (20%) structure indicators, and 5 (17%) outcome indicators. Of the indicators that were part of the final list, functional and structural aspects of glaucoma progression and the availability of surgical/laser procedures were the most prevalent. CONCLUSIONS: A set of 30 QIs for measuring the performance of glaucoma units was developed using a consensus methodology involving experts in the field. Their use as measurement standards would provide important information about unit operations and allow further implementation of quality improvements.

Predictors of Glaucoma After Pediatric Cataract Surgery.

PRCIS: Glaucoma after pediatric cataract surgery is common and challenging. Age at surgery and the presence of microcornea or other anterior segment (AS) abnormalities can be used to identify those at greatest risk. OBJECTIVE: To establish risk factors for developing glaucoma after pediatric cataract surgery [glaucoma following cataract surgery (GFCS)]. METHODS: Single-center, retrospective, longitudinal study of patients who underwent lensectomy for pediatric cataracts from 2008 to 2020. Included eyes presented with congenital or acquired pediatric cataracts or an anterior form of persistent fetal vasculature, and a follow-up of at least 1 year. Exclusion criteria were the presence of preexisting intraocular pressure elevation, congenital glaucoma, syndromic cataracts, and a history of trauma or uveitis. Demographic and clinical data were collected. Our primary outcome was the development of GFCS. Multivariable logistic regression with generalized estimating equations was used to model the association between potential predictors and the risk of GFCS. RESULTS: A total of 110 eyes from 74 patients were included, 38 with unilateral and 36 with bilateral pediatric cataract surgery. The average surgery age was 24.71 ± 37.26 months, with 74 eyes (67.3%) undergoing surgery ≤12 weeks of age. Patients were followed for 9.96 ± 3.64 years after surgery. Twenty-eight eyes (25.45%) developed GFCS, all requiring glaucoma surgery. In multivariable analysis, surgery before 12 weeks of age [odds ratio (OR): 34.74; P < 0.001], presence of microcornea (OR: 12.90; P = 0.002), and presence of other AS abnormalities (OR: 52.71; P < 0.001) were significantly associated with the development of GFCS. CONCLUSIONS: The development of GFCS is a common and relevant adverse event after pediatric cataract surgery whose management is challenging. Age at surgery, the presence of microcornea, and the presence of other AS abnormalities can be used to identify those at greatest risk.

Population confidence in the health system in 15 countries: results from the first round of the People's Voice Survey.

Population confidence is essential to a well functioning health system. Using data from the People's Voice Survey-a novel population survey conducted in 15 low-income, middle-income, and high-income countries-we report health system confidence among the general population and analyse its associated factors. Across the 15 countries, fewer than half of respondents were health secure and reported being somewhat or very confident that they could get and afford good-quality care if very sick. Only a quarter of respondents endorsed their current health system, deeming it to work well with no need for major reform. The lowest support was in Peru, the UK, and Greece-countries experiencing substantial health system challenges. Wealthy, more educated, young, and female respondents were less likely to endorse the health system in many countries, portending future challenges for maintaining social solidarity for publicly financed health systems. In pooled analyses, the perceived quality of the public health system and government responsiveness to public input were strongly associated with all confidence measures. These results provide a post-COVID-19 pandemic baseline of public confidence in the health system. The survey should be repeated regularly to inform policy and improve health system accountability.

Central obesity, body mass index, metabolic syndrome and mortality in Mediterranean breast cancer patients.

Obesity and metabolic disorders have been associated with poor outcomes in non-Mediterranean breast cancer (BC) patients. The purpose of this study was to investigate the prognostic potential of anthropometric variables in patients with early BC living in Southern Mediterranean region of Italy. We enrolled 955 consecutive early BC patients treated in hospitals in Naples between 2009 and 2013 (median follow-up 11.8-year ending 15/09/2022). Body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and metabolic syndrome (MetS) were collected. All-cause and BC-specific mortality were calculated. At the last day of contact 208 (22%) patients had died, 131 (14%) from BC. High WC (≥ 88 cm) or WHR (> 0.85) and the MetS were significantly associated with moderately increased risk of all-cause mortality (HR=1.39, 1.62, 1.61, respectively). A significant increased risk of BC-specific mortality was found in obese patients, in those with high WC, high WHR and those with MetS (HR=1.72, 1.71, 1.80, 1.81, respectively). Central obesity significantly increased total and BC-specific mortality particularly in pre-menopausal women and in luminal subtypes, while in post-menopause MetS was a stronger risk factor. Obesity and MetS may impair the effectiveness of BC therapies hence active lifestyle interventions are encouraged.

Suboptimal Intake of Fruits and Vegetables in Nine Selected Countries of the World Health Organization European Region.

The objective of this study was to characterize fruit and vegetable consumption in 9 selected countries of the World Health Organization (WHO) European Region. We analyzed data on fruit and vegetable intake and participant sociodemographic characteristics for 30,455 adults in 9 Eastern European and Central Asian countries via standardized STEPS survey methodology. Fruit and vegetable consumption across all countries was suboptimal, with a high percentage of populations not meeting the WHO-recommended intake of at least 5 servings (400 g) per day. Strengthened implementation of evidence-based policies to increase intake of fruit and vegetables is needed to reduce the burden of and disparities in NCDs.

Effect of Repeated Intravitreal Injections in Glaucoma Spectrum Diseases.

Purpose: To evaluate whether repeated intravitreal injections (IVI) with an anti-vascular endothelial growth factor (anti-VEGF) agent are associated with glaucomatous progression in eyes with glaucoma spectrum diseases (GSD). Methods: Single-center, retrospective, longitudinal study of patients with bilateral and similar GSD who: (1) received ≥8 IVI in only one eye during the study period; (2) had ≥2 retinal nerve fiber layer thickness (RNFL) measurements obtained by spectral-domain optical coherence tomography (SD-OCT) at least 12 months apart. The primary outcome was the absolute RNFL thickness change, comparing injected and fellow uninjected eyes. Linear mixed effects models were constructed, including a multivariable model. Results: Sixty-eight eyes from 34 patients were included, 34 injected and 34 fellow uninjected eyes. Average baseline age was 67.68±21.77 years with a follow-up of 3.66±1.89 years and 25.12±14.49 IVI. RNFL thickness decreased significantly from 80.92±15.78 to 77.20±17.35 µm (p<0.001; -1.18±1.93 µm/year) in injected eyes and from 79.95±17.91 to 76.61±17.97 µm (p<0.001; -1.07±0.98 µm/year) in uninjected eyes. In a multivariable linear mixed model of injected eyes, only higher baseline RNFL thickness (p < 0.001) significantly predicted higher absolute RNFL thickness loss. Neither absolute RNFL thickness variation (p=0.716) nor RNFL rate (p=0.779) was significantly different between paired injected and uninjected eyes. Absolute IOP variation was not significantly different between groups (16.62±4.77 to 15.09±4.34 mmHg in injected eyes and 17.68±5.01 to 14.50±3.39 mmHg in fellow uninjected eyes; p=0.248). The proportion of eyes receiving glaucoma medical treatment increased significantly in both groups (55.9% to 76.5% in injected eyes; p=0.039; 58.8% to 76.5% in uninjected eyes; p = 0.031). The number of glaucoma medications also increased significantly in both groups (1.03±1.11 to 1.59±1.18 glaucoma medications in injected eyes; p=0.003; 1.09±1.11 to 1.56±1.19 glaucoma medications in uninjected eyes; p=0.003). Conclusion: Repeated IVI do not seem to accelerate glaucomatous progression. Future studies with a longer follow-up are needed.

Pertinence of Salt-Related Knowledge and Reported Behaviour on Salt Intake in Adults: A Cross-Sectional Study.

The association between salt-related knowledge, attitude, behaviour (KAB) and actual salt consumption in Greek adults is uncertain. This study investigates the correlation between salt intake, gauged by 24-h urinary sodium excretion, with salt-related KAB. It further explores how socio-demographic factors influence these behaviors. Salt consumption was evaluated using a 24-h urinary sodium test, and compared to self-reported KAB data. Knowledge and behavior scores related to salt were computed. An overall cohort-adjusted model examined the relationship between daily salt consumption, knowledge and behavior scores, and certain covariates. Through the stratification by the cohort random effect, two models were established (Cohort I Adults; Cohort II Students) examining the same relationships of the overall cohort model. 463 Greek adults participated. The average salt intake was 9.54 g/day, nearly double the WHO recommendation. Significant differences in knowledge scores were noted based on sex, age, education, and BMI. A trend suggesting lower discretionary salt use with increased salt intake was observed (p = 0.06). However, comprehensive analysis revealed no direct correlation between salt intake and either knowledge (p = 0.562) or behavior scores (p = 0.210). The results emphasize the need for food product reforms by industry stakeholders and accelerated efforts towards reducing salt intake.

A generalizable deep learning regression model for automated glaucoma screening from fundus images.

A plethora of classification models for the detection of glaucoma from fundus images have been proposed in recent years. Often trained with data from a single glaucoma clinic, they report impressive performance on internal test sets, but tend to struggle in generalizing to external sets. This performance drop can be attributed to data shifts in glaucoma prevalence, fundus camera, and the definition of glaucoma ground truth. In this study, we confirm that a previously described regression network for glaucoma referral (G-RISK) obtains excellent results in a variety of challenging settings. Thirteen different data sources of labeled fundus images were utilized. The data sources include two large population cohorts (Australian Blue Mountains Eye Study, BMES and German Gutenberg Health Study, GHS) and 11 publicly available datasets (AIROGS, ORIGA, REFUGE1, LAG, ODIR, REFUGE2, GAMMA, RIM-ONEr3, RIM-ONE DL, ACRIMA, PAPILA). To minimize data shifts in input data, a standardized image processing strategy was developed to obtain 30° disc-centered images from the original data. A total of 149,455 images were included for model testing. Area under the receiver operating characteristic curve (AUC) for BMES and GHS population cohorts were at 0.976 [95% CI: 0.967-0.986] and 0.984 [95% CI: 0.980-0.991] on participant level, respectively. At a fixed specificity of 95%, sensitivities were at 87.3% and 90.3%, respectively, surpassing the minimum criteria of 85% sensitivity recommended by Prevent Blindness America. AUC values on the eleven publicly available data sets ranged from 0.854 to 0.988. These results confirm the excellent generalizability of a glaucoma risk regression model trained with homogeneous data from a single tertiary referral center. Further validation using prospective cohort studies is warranted.

Retinal OCT speckle as a biomarker for glaucoma diagnosis and staging.

This paper presents a novel image analysis strategy that increases the potential of macular Optical Coherence Tomography (OCT) by using speckle features as biomarkers in different stages of glaucoma. A large pool of features (480) were computed for a subset of macular OCT volumes of the Leuven eye study cohort. The dataset contained 258 subjects that were divided into four groups based on their glaucoma severity: Healthy (56), Mild (94), Moderate (48), and Severe (60). The OCT speckle features were categorized as statistical properties, statistical distributions, contrast, spatial gray-level dependence matrices, and frequency domain features. The averaged thicknesses of ten retinal layers were also collected. Kruskal-Wallis H test and multivariable regression models were used to infer the most significant features related to glaucoma severity classification and to the correlation with visual field mean deviation. Four features were selected as being the most relevant: the ganglion cell layer (GCL) and the inner plexiform layer (IPL) thicknesses, and two OCT speckle features, the data skewness computed on the retinal nerve fiber layer (RNFL) and the scale parameter (a) of the generalized gamma distribution fitted to the GCL data. Based on a significance level of 0.05, the regression models revealed that RNFL skewness exhibited the highest significance among the features considered for glaucoma severity staging (p-values of 8.6×10-6 for the logistic model and 2.8×10-7 for the linear model). Furthermore, it demonstrated a strong negative correlation with the visual field mean deviation (ρ=-0.64). The post hoc analysis revealed that, when distinguishing healthy controls from glaucoma subjects, GCL thickness is the most relevant feature (p-value of 8.7×10-5). Conversely, when comparing the Mild versus Moderate stages of glaucoma, RNFL skewness emerged as the only feature exhibiting statistical significance (p-value = 0.001). This work shows that macular OCT speckle contains information that is currently not used in clinical practice, and not only complements structural measurements (thickness) but also has a potential for glaucoma staging.

Should VV ECMO be considered as treatment option in COVID-19 infection after kidney transplant? A word of caution.

Several reports have shown that hospitalized kidney transplant recipients (KTR) had high mortality rates when infected with COVID-19. Extracorporeal Membrane Oxygenation (ECMO) has been shown to be an option for refractory respiratory failure in COVID-19 patients with variable rates of recovery. The outcome of ECMO in respiratory failure is highly related to cohort investigated and patient selection. Over a 10-month period in the height of COVID-19 pandemic 5 KTR patients were placed on ECMO with none of the patients surviving to discharge. All patients experienced multisystem organ failure (MSOF) and hematologic pathology while on ECMO. We concluded that COVID-19 in KTR patients presents with a refractory MSOF that is not well supported with ECMO in a traditional approach. Future work is needed to determine how to best support refractory respiratory failure in KTR patients with COVID-19.

Impact of COVID-19 lockdown on smoking and vaping: systematic review and meta-analysis.

OBJECTIVES: COVID-19 and the implementation of lockdowns have impacted daily lives worldwide. This systematic review and meta-analysis aimed to investigate the impact of lockdowns on the smoking and vaping behaviours of adults during the pandemic. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: A systematic literature search was conducted up to 28 April 2022 in the following databases: PubMed, Embase and Web of Science. RESULTS: In total, 77 studies met the inclusion criteria for this review. In 34 studies, an increase in smoking behaviour was reported for the majority of participants; however, in 21 and 18 studies, 'no change' and 'decrease' in smoking were the predominant responses, respectively. The results from the meta-analysis, which examined the change in the number of cigarettes smoked per day, showed no difference between the pre- and post-lockdown periods: 0.81 weighted mean difference (95% confidence interval, -0.59 to 2.21). Regarding vaping, three of seven studies reported an increase in smoking for the majority of participants, whereas 'no change' and 'decrease' were the predominant answers in the other four studies. CONCLUSIONS: The results show that lockdowns led most participants to increase smoking/vaping, whereas a decrease or cessation of smoking/vaping was only reported in the minority of participants. Attention should be given to the non-communicable diseases that could arise as a result of the increase in smoking/vaping during lockdowns, and further research in this area is needed.

Children's exposure to television advertising of unhealthy foods and beverages across four countries of WHO European Region.

OBJECTIVE: To compare the frequency and healthfulness of foods being advertised to children and adolescents in four countries of WHO European region. DESIGN: Cross-sectional quantitative study, guided by an adapted version of the WHO protocol. All recorded food advertisements were categorised by categories and as either 'permitted' or 'not permitted' for advertising to children in accordance with WHO Regional Office for Europe Nutrient Profile Model. SETTINGS: Four countries: Russia, Turkey, Kazakhstan and Kyrgyzstan. PARTICIPANTS: TV channels most popular among children and adolescents. RESULTS: Analysis included 70 d of TV broadcasting for all channels, during which time there were 28 399 advertisements. The mean number of advertisements per hour varied from eleven in Turkey and Kazakhstan to eight and two in Russia and Kyrgyzstan. In all countries, the majority of the food and beverages advertised should not be permitted for advertising to children according to the WHO Nutrient Profile Model. The mean number of non-permitted food and beverage advertisements per hour was high in Turkey and Kazakhstan (8·8 and 8·5 ads) compared with Russia (5·1) and Kyrgyzstan (1·9). Turkey was the only country where nutritional information was fully available, and no values were missing that prevented coding for some product categories. CONCLUSIONS: Results revealed that children and adolescents in four countries are exposed to a considerable volume of food and beverage advertisements, including sugary products on broadcast television. As such, policymakers should consider protecting youth by developing regulations to restrict these marketing activities within media popular with children.

[Evaluation of the Manchester Triage System in Patients with Acute Primary Angle Closure Attack: A Retrospective Study]. / Avaliação do Sistema de Triagem de Manchester em Doentes com Crise de Encerramento Agudo Primário do Ângulo Iridocorneano: Um Estudo Retrospetivo.

INTRODUCTION: Acute primary angle closure attack is an ophthalmological emergency. The aim of this study was to describe the cases diagnosed in the Emergency Department, by correlating the initial complaint with the Manchester triage level and ultimately the time needed until ophthalmological evaluation and iridotomy. MATERIAL AND METHODS: Retrospective analysis of the electronic medical records of patients with acute primary angle closure attack that attended the Ophthalmology Emergency Department of our tertiary center between January 2010 and December 2020. Overall, 2228 Emergency Department episodes coded with the diagnoses glaucoma or ocular hypertension were retrieved, followed by screening of each episode for correct identification of true acute primary angle closure attacks. Clinical data was gathered, including Manchester triage level, presenting complaint, intraocular pressure at presentation, first medical specialty that observed the patient, time until observation by Ophthalmology and time until laser iridotomy. RESULTS: Among the 120 patients identified, 84 (70%) were female and the mean age was 68 ± 12 years. Mean intraocular pressure at admission was 53.4 ± 12.4 mmHg, and 9.2% of patients presented only non-ocular complaints, while 9.2% presented mixed complaints (ocular and non-ocular). Most patients (68.1%) with only non-ocular or mixed complaints were triaged to a non-ophthalmologist (p < 0.001). Concerning the triage system, at admission, most patients (66.7%) were labelled yellow (urgent), while 9.2% and none were labelled as orange (very urgent) or red (emergent), respectively. Most patients (83.3%) were directly sent to Ophthalmology (properly triaged), while the remaining were incorrectly assigned to a non-ophthalmologist. Median time until observation by Ophthalmology was 49 minutes in the properly triaged group (min. 15, max. 404), while it was 288 minutes (min. 45, max. 871) in those who were incorrectly triaged (p < 0.001). Likewise, median time until treatment with laser iridotomy was 203 minutes in the properly triaged group (min. 22, max. 1440) and 353 minutes in the incorrectly triaged group (min.112, max. 947) (p < 0.001). CONCLUSION: Most patients with acute primary angle closure attack were not properly triaged according to the level of the Manchester triage system. There was a significant delay in the diagnosis and treatment of those patients who were first assigned to non-ophthalmologists. There is a need to raise awareness regarding the presenting signs and symptoms of an acute primary angle closure attack in order to avoid preventable vision loss.

Introdução: A crise de encerramento agudo primário do ângulo iridocorneano é uma emergência oftalmológica. O objetivo deste estudo foi descrever os casos admitidos no Serviço de Urgência do Centro Hospitalar Universitário São João, correlacionando a queixa inicial com o nível de triagem de Manchester atribuído e o tempo até observação por Oftalmologia e realização de iridotomia. Material e Métodos: Análise retrospetiva dos registos clínicos dos doentes com encerramento agudo primário do ângulo, admitidos no Serviço de Urgência entre janeiro de 2010 e dezembro de 2020. Foram revistos 2228 episódios com diagnóstico de glaucoma ou hipertensão ocular para identificação correta dos casos de crise de encerramento do ângulo. Foram extraídas variáveis, nomeadamente o nível de triagem de Manchester atribuído, queixa principal, pressão intraocular à admissão, especialidade responsável pelo primeiro contacto médico e tempos até observação por Oftalmologia e até iridotomia. Resultados: Foram identificados 120 doentes, 84 (70%) do sexo feminino, com idade média de 68 ± 12 (desvio padrão) anos. A pressão intraocular média à admissão foi de 53,4 ± 12,4 mmHg. Em 9,2% dos doentes a queixa principal foi não-ocular, enquanto 9,2% apresentavam queixas não-oculares e oculares associadas. A maioria (68,1%) dos doentes com queixas não-oculares ou mistas foi triada para um não-oftalmologista. Segundo o sistema de triagem, a maioria (66,7%) dos doentes foi triada com nível amarelo (urgente), 9,2% foram triados com laranja (muito urgente) e nenhum vermelho (emergente). O primeiro especialista a observar os doentes após a triagem foi um oftalmologista em 83,3% dos casos (corretamente triados), enquanto os restantes foram inicialmente observados por outra especialidade. O tempo mediano até observação por Oftalmologia foi de 288 minutos (min. 45, máx. 871) num doente incorretamente triado e 49 minutos (min. 15, máx. 404) (p < 0,001) em doentes corretamente triados. O tempo mediano até realização de iridotomia laser foi de 353 minutos (min. 112, máx. 947) nos doentes incorretamente triados e 203 minutos (min. 22, máx. 1440) nos corretamente triados (p < 0,001). Conclusão: A maioria dos doentes com crise de encerramento agudo primário do ângulo iridocorneano não foi triada de acordo com o grau de prioridade apropriado segundo o sistema de triagem de Manchester. Nos doentes que não foram imediatamente seguidos por Oftalmologia verificou-se um atraso significativo no diagnóstico e início do tratamento. Torna-se premente a consciencialização dos profissionais de saúde sobre esta condição clínica e a otimização do processo de triagem para minimizar a perda de visão.
