Abstract
Objetivo: Fornecer informações sobre a ocorrência e a eficácia do aconselhamento sobre o uso de tabaco por oftalmologistas a pacientes com doenças oculares associadas à tireoide.
Métodos: Analisamos os prontuários médicos eletrônicos de uma coorte digital de pacientes atendidos por oftalmologistas no Sistema de Saúde da Universidade da Pensilvânia entre o início de 2012 e o final de 2017 com os códigos da Classificação Internacional de Doenças (CID) para a doença de Graves, exoftalmia tireotóxica ou doença ocular associada à tireoide. Os históricos de uso de tabaco foram registrados na primeira e na última visita ao consultório de Oftalmologia, ou na visita mais próxima no tempo. A quantidade de maços/dia (mpd) e todas as anotações feitas nas visitas ao consultório de Oftalmologia foram analisadas para aconselhamento sobre o uso de tabaco.
Resultados: Um total de 435 indivíduos preencheram os critérios de inclusão, dos quais 72 (16,6%) estavam fumando ativamente no momento do primeiro encontro. Apenas 57 (79,2%) desses indivíduos que fumam ativamente registraram queixas relacionadas ao tabagismo, sendo que 34 (59,6%) deles receberam alguma forma de aconselhamento sobre o uso de tabaco. Ao todo, 9 (26,5%) indivíduos dentre os que receberam aconselhamento sobre tabaco e 1 (4,3%) que não teve aconselhamento registrado pararam de fumar (diferença de risco de 22,1%; IC 95%, [1,7%, 39,1%]; p=0,04). Dentre aqueles que receberam aconselhamento, 17 (50,0%) reduziram seus mpd, além de 7 (30,4%) daqueles que não tiveram aconselhamento (diferença de risco de 19,6%; IC 95% [-6,3%, 41,3%]; p=0,18). No geral, 14 (25,5%) dos 55 oftalmologistas que tiveram um paciente fumante ativo registraram evidências de aconselhamento sobre o uso de tabaco.
Conclusões: Os resultados deste estudo revelam tanto as oportunidades perdidas de aconselhamento sobre o uso do tabaco quanto a eficácia do aconselhamento no contexto de doenças oculares associadas à tireoide.

Abstract
PURPOSE: To report the ophthalmological signs, symptoms, and clinical management observed during an unprecedented outbreak of chemical ocular injuries related to cosmetic hair ointments in Brazil.
METHODS: This descriptive, cross-sectional study reviewed medical records of patients treated at the emergency center of Fundação Altino Ventura for chemical ocular trauma associated with cosmetic hair ointment use between February 2022 and February 2023. Records with incomplete medical information were excluded.
RESULTS: The study included 168 patients (95.2% [n=160] female), with a mean age of 30.8 ± 9.7 years. The most frequently reported symptoms at presentation were pain (167/168, 99.4%) and photophobia (92/168, 54.8%). Severe pain was reported by 137 patients (80%). Keratitis was present in 280 of 336 eyes (83.3%), conjunctival hyperemia in 256 eyes (76.4%), and corneal abrasions in 174 eyes (51.8%). A decrease in visual acuity (worse than 20/25) was documented in 18.5% (31/168) of cases. Lubricants, antibiotics, and re-epithelialization
ointments were prescribed to 64.8% (109/168) of the patients. Topical corticosteroids and oral vitamin C were administered to 34% (57/168) and 1.2% (2/168) of patients, respectively. Followup visits were required in 19% (33/168) of cases.
CONCLUSION: The outbreak of chemical ocular injuries linked to cosmetic ointments used for braiding and hair modeling in Brazil was marked by intense ocular pain, conjunctival hyperemia, keratitis, and corneal abrasions. Most patients were treated with lubricants, antibiotics, and re-epithelialization ointments, although approximately one-fifth required followup care, and one-third received additional treatment with either topical corticosteroids and/or oral vitamin C.

Abstract
Objetivo: Avaliar as características clínicas de pacientes pediátricos com blefaroptose adquirida unilateral, transitória e de início agudo.
Métodos: Neste estudo retrospectivo, foram revisados prontuários clínicos entre abril de 2015 e junho de 2020. Os pacientes foram avaliados em termos de características demográficas, manifestações neurológicas e oftalmológicas associadas, duração dos sintomas, etiologia e achados de imagem. Foram excluídos pacientes com blefaroptose congênita e com blefaroptose adquirida de etiologia crônica.
Resultados: Foram incluídos neste estudo 16 pacientes pediátricos (10 masculinos e 6 femininos) com blefaroptose adquirida transitória unilateral de início agudo. A média de idade dos pacientes foi de 6,93 ± 3,16 anos. As causas etiológicas mais comumente identificadas foram trauma em 7 pacientes (43,75%) e infecção (casos parainfecciosos) em 5 pacientes (31,25%). Além disso, a síndrome de Miller-Fisher, a síndrome de Horner secundária a neuroblastoma, a síndrome de Brown adquirida e pseudotumor cerebral foram determinados como causas etiológicas em um paciente cada uma. Achados oculares adicionais estavam associados à blefaroptose em 7 pacientes (58,33%). Foi observada a resolução espontânea da blefaroptose, sem tratamento, em todos os pacientes, exceto nos pacientes com síndrome de Miller-Fisher, neuroblastoma e pseudotumor cerebral. Nenhum paciente precisou de tratamento cirúrgico. Morbidades oculares, como ambliopia, não foram encontradas em nenhum paciente.
Conclusão: Este estudo demonstrou que a blefaroptose transitória unilateral de início agudo, rara na infância, pode regredir sem a necessidade de tratamento cirúrgico na população pediátrica. No entanto, também não deve ser esquecido que patologias graves que requerem tratamento podem se apresentar com blefaroptose.

Abstract
Objetivo: Determinar a incidência de emergências oculares em um centro oftalmológico de referência no Brasil.
Métodos: O banco de dados de prontuários da Fundação Altino Ventura, Recife, Brasil, foi analisado retrospectivamente e incluiu pacientes atendidos, entre janeiro de 2017 e janeiro de 2018, na sala de emergência oftalmológica. Foram excluídos os prontuários com dados incompletos e com quadros ambulatoriais. Apenas o primeiro atendimento na emergência foi considerado para análise.
Resultados: Em um ano, 134.788 pacientes (idade média de 38,7 ± 22 anos [0-99 anos]) foram admitidos na emergência da Fundação Altino Ventura. Os diagnósticos mais frequentes foram conjuntivite (52.732 casos [37,3%]), blefarite (7.213 casos [5,1%]) e corpo estranho na córnea/conjuntiva (6.925 casos [4,9%]). Corpo estranho na córnea/conjuntiva e trauma ocular foram cerca de 8 vezes e 2 vezes mais incidente em indivíduos do sexo masculino, respectivamente (p<0,001 em ambos). Triquíase e blefarite afetaram ~2 vezes mais pacientes do sexo feminino, respectivamente (p<0,001 em ambos). Corpo estranho na córnea/conjuntiva e trauma ocular afetaram mais pacientes em idade produtiva (>15 anos), enquanto úlcera, blefarite e triquíase da córnea afetaram mais pacientes idosos. Todos os grupamentos de diagnóstico (doenças infecciosas, trauma ocular, corpos estranhos, retinopatias, doenças das pálpebras, doenças da córnea, crise glaucomatosa e doenças neurooftalmológicas) foram mais incidentes na primavera (valor de p<0,001).
Conclusão: As emergências oftalmológicas mais comuns no presente estudo foram as doenças infecciosas e o corpo estranho. Porém, a incidência das emergências oculares são fluências pela faixa etária e gênero do paciente, além da época do ano.

Abstract
PURPOSE: This clinical study aimed to assess the effectiveness of microemulsion artificial tears containing povidone and propylene glycol in the management of dry eye disease. Secondary objectives included evaluating improvements in tear-film stability, measured by tear break-up time and corneal staining scores, along with the tolerability and safety of the formulation.
METHODS: This was a prospective, single-arm interventional study involving 30 participants (52 eyes) diagnosed with dry eye disease. Participants self-administered the investigational eye drops twice daily for 28 consecutive days. Primary and secondary outcomes included changes in the Ocular Surface Disease Index, tear break-up time, and corneal staining scores. Adverse events were documented throughout the study period.
RESULTS: Significant improvements in Ocular Surface Disease Index scores were observed, reflecting a reduction in dry eye disease symptoms. Tear break-up time increased notably between baseline and follow-up assessments, with the proportion of eyes exhibiting tear break-up time ≥10 srising from 25.0% to 63.5%. Additionally, the percentage of eyes with a corneal staining score of zero improved from 23.1% to 69.2%. Conjunctival staining also decreased, with the proportion of eyes with scores of 2 and 3 dropping from 11.5% to 3.8% and 5.8% to 0%, respectively.
CONCLUSIONS: The findings suggest that povidone and propylene glycol-based artificial tears significantly enhance tear-film stability and alleviate symptoms in patients with mild to moderate dry eye disease, with minimal adverse effects. This formulation represents a safe and effective short-term treatment option for dry eye disease management.

Abstract
PURPOSE: This study aimed to evaluate the relationship between the objective severity of dry eye disease subjective symptoms, and corneal sensitivity.
METHODS: The study included 62 eyes from 31 healthy volunteers and 150 eyes from 75 patients diagnosed with dry eye disease . Participants underwent the Schirmer I test, tear break-up time assessment, and corneal staining evaluation using the Oxford Scale. Subjective symptoms were assessed through the Ocular Surface Disease Index questionnaire and a modified Ocular Surface Pain Score questionnaire. Corneal sensitivity was measured in five corneal regions using a Cochet-Bonnet esthesiometer. Dry eye disease severity was graded from 1 to 5 based on the Oxford Scale. Comparative analyses were performed.
RESULTS: Schirmer I and tear break-up time values were significantly lower in the DED group, while Ocular Surface Disease Index and Ocular Surface Pain Score were significantly higher (p<0.001 for all). Corneal sensitivity in all quadrants was significantly lower in DED patients (p<0.001 for all). A strong correlation was observed between the Ocular Surface Pain Score and the Ocular Surface Disease Index (r=0.983, p<0.001). Central corneal sensitivity exhibited a moderate positive correlation with Schirmer I and tear break-up time (p<0.001, r=0.583 and 0.657, respectively) and a moderate negative correlation with Ocular Surface Disease Index and Ocular Surface Pain Score (p<0.001, r=0.625 and −0.631, respectively). Disease severity progression was associated with increased Ocular Surface Disease Index and Ocular Surface Pain Score, but no statistically significant difference was found between Grades 3 and 5. Similarly, corneal sensitivity decreased with advancing disease severity, yet no significant difference was observed between Grades 4 and 5.
CONCLUSION: Corneal sensitivity decreases in dry eye disease and is negatively correlated with disease severity. Subjective symptoms increase with disease progression and show a positive correlation with severity. The absence of significant differences between the advanced stages suggests that neuropathic mechanisms and subbasal nerve plexus deterioration play a role in chronic and late-stage dry eye disease.

Abstract
PURPOSE: To describe a 2019 acute toxoplasmosis outbreak in the city of São Paulo, Brazil, and to evaluate the laboratory serological profile for toxoplasmosis for three consecutive years. The ophthalmological manifestations of the patients involved in the outbreak were also studied.
METHODS: A cross-sectional descriptive study of a toxoplasmosis outbreak in São Paulo, Brazil, between February and May 2019. Epidemiological data were described, as were the observed ocular manifestations. As part of this study the number of patients with positive IgM toxoplasmosis serology was obtained from a large laboratory network (DASA) for three consecutive years, including the year of the outbreak (2018, 2019, 2020).
RESULTS: Eighty-three individuals were identified in the outbreak and two clusters were studied. The clinical picture of at least 77% of the patients, the epidemiological analysis, and the short incubation period (5-8 days) suggested contamination by oocysts. Serological laboratory data analysis revealed an increase of positive toxoplasmosis IgM in 2019 of 73% compared to the previous year. Ophthalmological examination revealed that at least 4.8% of the patients developed toxoplasmic retinochoroiditis, none of whom had been treated during the acute systemic disease.
CONCLUSION: Our findings indicate vegetable contamination as the possible source of this outbreak, a high prevalence of toxoplasmosis in São Paulo during the outbreak period, and a drop in the number of tests during the COVID-19 pandemic. Retinochoroiditis was observed in at least 4.8% of the cases. We confirm the need to implement effective means for the prevention, diagnosis, and treatment of the disease. This may involve raising awareness among the population of the importance of vegetable hygiene, and improved quality control of food and water.
