Effect of the COVID-19 pandemic on cataract surgery by residents who had routine surgical simulator training during residency

ABSTRACT Purpose: To assess the effect of the coronavirus disease 2019 (COVID-19) pandemic on cataract surgery by residents who had mandatory surgical simulator training during residency. Methods: In this retrospective, observational analytical study, the total number of cataract surgeries and surgical complications by all senior residents of 2019 (2019 class; prepandemic) and 2020 (2020 class; affected by the reduced number of elective surgeries due to the COVID-19 pandemic) were collected and compared. All residents had routine mandatory cataract surgery training on a virtual surgical simulator during residency. The total score obtained by these residents on cataract challenges of the surgical simulator was also evaluated. Results: The 2020 and 2019 classes performed 1275 and 2561 cataract surgeries, respectively. This revealed a reduction of 50.2% in the total number of procedures performed by the 2020 class because of the pandemic. The incidence of surgical complications was not statistically different between the two groups (4.2% in the 2019 class and 4.9% in the 2020 class; p=0.314). Both groups also did not differ in their mean scores on the simulator's cataract challenges (p<0.696). Conclusion: Despite the reduction of 50.2% in the total number of cataract surgeries performed by senior residents of 2020 during the COVID-19 pandemic, the incidence of surgical complications did not increase. This suggests that surgical simulator training during residency mitigated the negative effects of the reduced surgical volume during the pandemic.

Firework-related ocular trauma in Pernambuco, Brazil / Trauma ocular por fogos de artifício em Pernambuco, Brasil

ABSTRACT Purpose: This study aimed to describe the demographic and clinical characteristics of victims of fireworkrelated ocular trauma treated at the ophthalmologic emergency de partments of two reference centers in Pernambuco, Brazil, and to identify risk factors related to poor visual prognosis. Methods: We retrospectively evaluated the medical records of patients admitted in emergency departments with a report of firework-related trauma between January 2012 and December 2018. Data collected included patient's age, sex, place of origin, month and year of the accident, ocular structures affected, characteristics of the injuries, and type of treatment that patients received. For patients who were followed for >30 days, the final visual acuity and patient's origin were analyzed. Results: Three hundred and seventy eyes from 314 patients were included, of which 248 (79.0%) were male and 160 (51.0%) were from the metropolitan region of Recife. The mean patient age was 25.6 ± 18.8 years. In 56 (17.8%) patients, the ocular trauma was bilateral. A total of 152 (48.4%) cases occurred in June. The most affected sites were the eyelids in 91 (24.6%) eyes and ocular surface in 252 (68.1%). Surgical treatment was required in 87 (23.5%) eyes. After clinical and surgical management, 37 (10.0%) eyes presented final visual acuity of <20/400. Of these, 34 (91.9%) eyes were from patients from the countryside or from another state. Patients from the countryside presented higher risk of developing blindness after a firework trauma than those from the metropolitan area (odds ratio of 5.46). Conclusions: Victims of firework-related ocular trauma were mostly male, from the metropolitan region of Pernambuco state and mainly pediatric patients or economically active. Those coming from the countryside and other states had higher risk of developing blindness

RESUMO Objetivos: Descrever as características demográficas e clínicas das vítimas de trauma ocular por fogos de artifício atendidas nas emergências oftalmológicas de dois centros de referência em Pernambuco e identificar fatores relacionados a mau prognóstico visual. Métodos: Avaliação retrospectiva dos prontuários de pacientes admitidos na emergência oftalmológica com história de trauma por fogos de artifício entre janeiro de 2012 e dezembro de 2018. A coleta de dados incluiu idade, gênero, procedência, mês e ano do acidente, estruturas oculares acometidas e características das lesões, além do tipo de tratamento a que os pacientes foram submetidos. Naqueles pacientes acompanhados por mais de 30 dias, analisou-se a acuidade visual final e a associação com sua procedência. Resultados: Foram incluídos 370 olhos de 314 pacientes. Destes, 248 (79,0%) vítimas eram do sexo masculino e 160 (51,0%) da região metropolitana do Recife, com uma média de idade de 25.6 ± 18.8 anos. Em 56 (17,8%) dos casos o trauma foi bilateral. No mês de junho ocorreu um total de 152 (48,4%) casos. Os sítios mais acometidos foram pálpebras em 91 (24,6%) olhos e superfície ocular em 252 (68,1%). O tratamento cirúrgico foi necessário em 87 (23,5%) olhos. Após manejo clínico-cirúrgico, 37 (10.0%) olhos desenvolveram visão pior do que 20/400. Destes, 34 (91,9%) olhos eram de pacientes do interior do estado de Pernambuco ou de outro estado. Os pacientes provenientes do interior do estado apresentaram maior chance de desenvolver cegueira quando comparados aos que eram provenientes da região metropolitana (Odds Ratio de 5,46). Conclusões: As vítimas de trauma ocular por fogos de artificio foram em sua maioria do sexo masculino, procedentes da região metropolitana do estado e das faixas etárias pediátrica e economicamente ativa. Aqueles provenientes do interior ou de outros estados apresentaram maior chance de desenvolver cegueira.

Analysis of ocular surface and quality of life in patients with corneal and conjunctival tumors / Análise da superfície ocular e qualidade de vida em pacientes com tumores córneo-conjuntivais

ABSTRACT Purpose: To evaluate the impact of corneal and conjunctival tumors on the ocular surface and quality of life of patients before and after surgical treatment. Methods: This prospective study conducted a preoperative and 30- and 90-day postoperative assessment of patients diagnosed with conjunctival and corneal tumors. Demographic data were collected preoperatively. The 12-Item Short-Form Health Survey (SF-12) and Ocular Surface Disease Index (OSDI) questionnaires were applied to assess patients' quality of life and perception of their vision-related functions. The tear breakup time and Schirmer tests were performed for ocular surface evaluation. The tumor extensions were measured using ImageJ image analysis software. Results: Twenty-three patients were enrolled. The mean age at examination was 52.8 ± 17.3 years (range: 27-9 years). The most common tumor type was squamous cell carcinoma (61.5%). The patients' visual acuity improved significantly at 1 month and 3 months (p=0.018 and p=0.036, respectively). No significant differences were found between tear breakup time and Schirmer tests preoperatively and at 3 months postoperatively (p=0.150 and p=0.490, respectively). The SF-12 scores demonstrated significant differences between the preoperative and 30- and 90-day postoperative mental components (p=0.008 and p=0.026, respectively). Tumor extension was 868.7 ± 344.9 pixels (range, 224.6-1481.6 pixels) and were significantly correlated with the preoperative (p=0.011), 30-day postoperative (p=0.017), and 90-day postoperative (p=0.012) SF-12 mental components, as well as the emotional component at the 30th postoperative day (p=0.016). Conclusion: Patients with corneal and conjunctival tumors improved their ocular symptoms, visual acuity, and the emotional component of their quality of life after surgical excision of the tumor.

RESUMO Objetivo: Avaliar o impacto dos tumores cór­neo-conjuntivais na superfície ocular e na qualidade de vida dos pacientes antes e após o tratamento cirúrgico. Métodos: Este estudo prospectivo conduziu uma avaliação pré-operatória e com 30 e 90 dias de pós-operatório de pacientes com diagnóstico de tumores de córnea e conjuntiva. Os dados demográficos foram coletados no pré-operatório. Os questionários Health Survey Short-Form (SF-12) e Ocular Surface Disease Index (OSDI) foram aplicados para avaliar a qualidade de vida dos pacientes e a percepção de suas funções relacionadas à visão. Os testes tear break-up time (TBUT) e Schirmer foram realizados para avaliação da superfície ocular. A extensão do tumor foi medida usando o programa ImageJ. Resultados: Vinte e três pacientes foram incluídos. A média de idade foi de 52,8 ± 17,3 anos (27-79 anos). O tipo mais comum de tumor foi o carcinoma de células escamosas (61,5%). A acuidade visual dos pacientes melhorou significativamente em 1 mês e 3 meses (p=0,018 e p=0,036, respectivamente). Não houve diferenças significativas entre os testes tear break-up time e Schirmer no pré-operatório e com 3 meses de pós-operatório (p=0,150 e p=0,490, respectivamente). Os escores do SF-12 demonstraram que o componente mental apresentou diferença estatisticamente significante entre o pré-operatório e no 30 e 90 dias de pós-operatório (p=0,008 e p=0,026, respectivamente). A extensão do tumor foi de 868,7 ± 344,9 pixels (intervalo, 224,6-1481,6 pixels) e foram significativamente correlacionados com o componente mental de SF-12 no pré-operatório (p=0,011), 30 (p=0,017) e 90 dias de pós-operatório (p=0,012), e o componente emocional no 30º dia de pós-operatório (p=0,016). Conclusão: Pacientes com tumores córneo-conjuntivais melhoraram os sintomas oculares, a acuidade visual e o componente emocional da qualidade de vida após a excisão cirúrgica do tumor.

Central retinal artery occlusion with cilioretinal artery sparing secondary to COVID-19: Additional ocular complication

We describe a 68-year-old female patient with unilateral central retinal artery occlusion (CRAO) with cilioretinal artery sparing post-coronavirus disease 2019 (COVID-19) infection. The patient presented with acute vision loss in the left eye 11 days after discharge from a severe COVID-19 infection, with altered D-dimer, C-reactive protein, and fibrinogen levels. The best-corrected visual acuity (BCVA) in the left eye was 20/400; fundoscopic examination revealed diffuse pallor retina with a patent arterial branch from the optic disk to the fovea, confirmed by fluorescein angiography. CRAO with a cilioretinal artery sparing post-COVID-19 may be considered an additional ocular manifestation of the post-acute COVID-19 syndrome spectrum.

Epidemiological and clinical analyses of corneal transplants performed in a reference eye center in Recife, Brazil / Análise epidemiológica e clínica dos transplantes de córnea realizados em um centro de referência oftalmológica em Recife, Brasil

ABSTRACT Purpose: To evaluate the epidemiological and clinical profiles of corneal transplants performed in a reference eye center in Recife, state of Pernambuco, Northeastern Brazil. Methods: This cross-sectional study collected epidemiological and clinical data from the medical records of patients who underwent keratoplasty at the Altino Ventura Foundation between January and December 2017. Results: A total of 356 procedures were performed in 327 patients, of whom 165 (50.5%) were female. The mean age at surgery was 50.9 ± 22.6 years (range, 10-89 years). Most patients (n=152 [46.5%]) were from the capital and metropolitan areas. The mean waiting time for keratoplasty was 52.4 ± 58.9 days (range, 0-460 days). The main indications for keratoplasty were infectious keratitis (n=88 [24.7%]), keratoconus (n=80 [22.5%]), and previous transplant failure (n=75 [21.1%]). Penetrating keratoplasty was the most common surgical technique performed (n=213 [59.9%]) and more frequently performed in men (n=132 [76.7%]), whereas posterior lamellar transplant (n=143 [41.1%]) was more frequently performed in women (p<0.001). Conclusion: Infectious keratitis was the main indication for keratoplasty, which was similarly performed in economically active adults of both sexes. Penetrating keratoplasty was more frequently performed in men and lamellar transplants in women.

RESUMO Objetivo: Avaliar o perfil clínico e epidemiológico dos transplantes de córnea realizados em um centro de referência oftalmológica de Recife no estado de Pernambuco, localizado no nordeste do Brasil. Métodos: Esse estudo transversal coletou através de prontuários médicos dados clínicos e epidemiológicos de pacientes submetidos a ceratoplastia na Fundação Altino Ventura, de janeiro a dezembro de 2017. Resultados: Um total de 356 procedimentos foram realizados em 327 pacientes dos quais 165 (50.5%) eram mulheres. A média de idade na cirurgia foi de 50.9 ± 22.6 anos (variação, 10 - 89 anos). A maioria dos pacientes (n=152 [46.5%]) era da capital e região metropolitana. A média de tempo de espera na fila para o transplante de córnea foi de 52.4 ± 58.9 dias (variação, 0 - 460 dias). As principais indicações de transplante foram ceratite infecciosa (n=88 [24.7%]), ceratocone (n=80 [22.5%]) e falência de transplante prévio (n=75 [21.1%]). Transplante penetrante foi a técnica mais realizada (n=213 [59.9%]) e foi mais comum em homens (n=132 [76.7%]), enquanto os transplantes lamelares posteriores (n=143 [41.1%]) foram mais realizados nas mulheres (p<0.001). Conclusão: Ceratites infecciosas foram a causa mais comum de transplante, com prevalência similar em adultos economicamente ativos de ambos os sexos. Transplante penetrantes foram os prevalentes em homens e os transplantes lamelares em mulheres.

Isolated abducens nerve palsy associated with coronavirus disease: an 8-month follow-up / Paresia isolada do nervo abducente associada ao COVID-19: 8 meses de seguimento

ABSTRACT We report the case of a previously healthy 48-year-old man who developed an isolated abducens nerve palsy 18 days after presenting with coronavirus disease (COVID-19) confirmed by reverse transcriptase polymerase chain reaction. His main complaint at arrival was double vision. Ocular examination revealed a sixth cranial nerve palsy in the left eye. The incomitant esotropia at arrival was 30 prism diopters. Abduction was markedly limited, while adduction was normal in the left eye. The patient underwent complete clinical, neurological, and neuroimaging investigations, including cerebrospinal fluid sample analysis to rule out infectious causes. A conservative approach with orthoptic therapy and Fresnel prism was opted. Eight months after the onset of COVID-19, regression of the strabismus was observed, and the patient reported complete recovery of the diplopia. This case suggests that isolated abducens nerve palsy caused by severe acute respiratory syndrome coronavirus 2 infection may improve with a conservative approach.

RESUMO Reportamos o caso de homem previamente hígido, 48 anos, com paralisia isolada do nervo abducente 18 dias após infecção pelo novo coronavírus (COVID-19) confirmada por reação cadeia polimerase de transcriptase reversa. A principal queixa do paciente na admissão era diplopia. O exame ocular revelou paralisia do sexto nervo craniano do olho esquerdo. Esotropia incomitante no exame inicial media 30 dioptrias prismáticas. Abdução estava limitada com adução completa no olho esquerdo. O paciente foi submetido a investigação clínica e neurológica com exame de neuroimagem, incluindo análise de amostra do líquido cefalorraquidiano para descartar causas infecciosas. Optou-se por abordagem conservadora com terapia ortóptica e prisma de Fresnel. Oito meses após a infecção pelo COVID-19, o paciente evoluiu com regressão do estrabismo e informou recuperação completa do quadro. Este relato sugere que paralisia isolada do nervo abducente causada por SARS-CoV-2 pode melhorar com abordagem conservadora.

Effects of COVID-19 pandemic on stress level of residents and fellows during ophthalmology training

Purpose: To evaluate the impact of coronavirus disease 2019 (COVID?19) on the mental health of residents and fellows in ophthalmology. Methods: A questionnaire composed of 42 questions was applied to Brazilian residents and fellows in Ophthalmology. The questionnaire addressed the demographics of participants, their working conditions before and during the COVID?19 pandemic, and the Perceived Stress Scale (PSS?10). Results: The study had a total of 271 participants in Ophthalmology training, from which 100 were fellows and 171 were residents. Before the pandemic, Ophthalmology residents and fellows had a higher workload (P < 0.001), and residents worked more hours than fellows (P = 0.001). During the pandemic, the workload of both residents and fellows decreased and equalized (P = 0.195). No correlation was found between the working hours during the pandemic and their stress level were observed (P = 0.760). Higher stress scores were identified in women ophthalmologists (P = 0.001) as well as in residents and fellows that had their surgical training interrupted during the pandemic (P < 0.001). Conclusion: The stress level of residents and fellows during the COVID?19 pandemic was similar, however, those that had their surgical training interrupted during the pandemic presented higher level of stress. Female physicians also presented higher level of stress compared to male physicians

Ophthalmological manifestations of the Schuurs-Hoeijmakers syndrome: a case report / Manifestações oftalmológicas da Síndrome de Schuurs-Hoeijmakers: relato de caso

ABSTRACT This is a case report of a 2-year-old male patient with cognitive delay, facial abnormalities, and microcornea in the right eye, who was referred for ophthalmological investigation. The initial ophthalmological examination revealed hypertelorism, epicanthus, nystagmus, esotropia, and microcornea in the right eye. The examination under anesthesia revealed microphthalmia in the right eye, and iris, retina, and optic nerve coloboma in both eyes. Whole exome sequencing revealed evidence of a heterozygotic pathogenic variant in PACS1. The PACS1 pathogenic variant in association with the clinical findings confirmed the diagnosis of Schuurs-Hoeijmakers syndrome. To our knowledge, this is the first report to describe microcornea and microphthalmia as additional ocular manifestations of Schuurs-Hoeijmakers syndrome.

RESUMO Trata-se de um relato de caso de um paciente do sexo masculino de 2 anos de idade com atraso cognitivo, anormalidades faciais e microcórnea no olho direito encaminhado para investigação oftalmológica. O exame oftalmológico inicial evidenciou hipertelorismo, epicanto, nistagmo, esotropia e microcórnea no olho direito. O exame sob anestesia revelou microftalmia no olho direito e coloboma de íris, retina e nervo óptico em ambos os olhos. Foi realizado sequenciamento completo do exoma que mostrou uma variante patogênica heterozigótica no PACS1. A variante patogênica no PACS1 em associação com os achados clínicos apresentados confirmou o diagnóstico da síndrome de Schuurs-Hoeijmakers). Acredita-se este seja o estudo a descrever microcórnea e microftalmia como manifestações oculares adicionais da síndrome de Schuurs-Hoeijmakers.

Evaluation of microbial contamination in multi-dose fluorescein eyedrops in a reference eye center / Avaliação da contaminação microbiana em colírios multi-dose de fluoresceína em um centro oftalmológico de referência

ABSTRACT Purpose: To analyze the presence of microorganisms in fluorescein eyedrops used in a reference eye center in Recife-PE. Methods: This real-life and masked study evaluated fluorescein eyedrops used at the Altino Ventura Foundation in May 2019. Cultures were performed according to exposure times; I) three eyedrop bottles were analyzed after one day of use, II) three eyedrop bottles after 4 d of use, III) three eyedrop bottles after 8 d of use, and IV) three unopened bottles used as control. Samples were collected from the bottle's tip, instilled drop, and residual fluid. After incubation, all colonies were analyzed and identified through biochemical tests. Results: The contamination rate of the fluorescein eyedrop bottles in this study was 55.5% (5/9 vials). There was no contamination in the control group. The highest contamination was seen in one day exposed eyedrops, in 100% of the bottles. The bottle's tip had a higher rate of contamination compared to the drop and residual fluid. Gram-positive bacteria were isolated in 7/27 (25.9%) samples. Growth of fungi or gram-negative bacteria was not observed. Conclusion: The identification of gram-positive bacteria predominantly on the tip of the fluorescein eyedrop bottles suggests inadequate handling as the main cause of contamination.

RESUMO Objetivo: Analisar a presença de microrganismos nos colírios de fluoresceína utilizados em um centro oftalmológico de referência em Recife-PE. Métodos: Este estudo de vida real e mascarado avaliou colírios de fluoresceína utilizados na Fundação Altino Ventura em maio/2019. As culturas foram realizadas de acordo com os diferentes tempos de exposição: I - três frascos de colírio foram analisados após 1 dia de uso; II - três frascos de colírio após 4 dias de uso; III - três frascos de colírio após 8 dias de uso; IV - três garrafas fechadas foram usadas como grupo controle. As amostras foram coletadas da ponta do frasco, da gota instilada e do líquido residual interior. Após incubação, todas as colônias foram analisadas e identificadas através de testes bioquímicos. Resultados: A taxa de contaminação dos frascos de colírio de fluoresceína neste estudo foi de 55,5% (5/9 frascos). Não houve contaminação no grupo controle. A maior contaminação foi observada os colírios expostos de um dia - 100% dos frascos. A ponta da garrafa teve uma maior taxa de contaminação em comparação com as culturas de gota e de fluido residual inferior. Bactérias gram-positivas foram isoladas em 7/27 amostras (25,9%). Não houve crescimento de fungos ou bactérias Gram-negativas. Conclusão: A identificação de bactérias Gram-positivas predominantemente na ponta dos frascos de colírio de fluoresceína sugere manuseio inadequado como a principal causa de contaminação de colírios multidose.

Vogt-Koyanagi-Harada syndrome: a discussion about resistance to corticotherapy / Vogt-Koyanagi-Harada: uma discussão sobre resistência à corticoterapia

ABSTRACT Vogt-Koyanagi-Harada (VKH) syndrome is an inflammatory condition of unknown etiology that can affect the eye. The most common ocular manifestation related to VKH is bilateral diffuse uveitis associated to exudative retinal detachment. Although these patients respond well to steroid pulse therapy, we report a case of a 44-year-old female patient presenting bilateral exudative retinal detachment and clinical diagnosis of VKH, who did not respond to the first cycle of 3-day pulse therapy with methylprednisolone. The exudation was reabsorbed only after a second cycle of steroid therapy.

RESUMO A doença de Vogt-Koyanagi-Harada é inflamatória e de etiologia desconhecida, podendo afetar o olho. A manifestação ocular mais comum relacionada à doença de Vogt-Koyanagi-Harada é a uveíte difusa bilateral associada ao descolamento exsudativo da retina. Embora esses pacientes respondam bem à pulsoterapia com esteroides, relatamos um caso de paciente de 44 anos que apresentou descolamento exsudativo bilateral da retina com diagnóstico clínico de doença de Vogt-Koyanagi-Harada que não respondeu ao primeiro ciclo de pulsoterapia de 3 dias com metilprednisolona. A exsudação apenas reabsorveu após uma segunda rodada de terapia com esteroides.

Descemets membrane endothelial keratoplasty for acute corneal hydrops: a case report / Ceratoplastia endotelial com membrana de descemet para hidrópsia corneana aguda: relato de caso

ABSTRACT Here, we describe the result of a Descemet's membrane endothelial keratoplasty for acute corneal hydrops in a 45-year-old female with keratoconus, who presented with severe visual loss in her OS. The patient's best-corrected visual acuity was 20/80 in the right eye and hand motion in the OS. Slit-lamp examination revealed an extensive tear of the Descemet's membrane and stromal corneal edema in the OS. We opted for Descemet membrane endothelial keratoplasty. Twelve months postoperatively, the patient had a best-corrected visual acuity of 20/50 in the OS.

RESUMO Trata-se de uma paciente do sexo feminino, de 45 anos, portadora de ceratocone, submetida a uma ceratoplastia endotelial com membrana Descemet após apresentar um quadro de perda de visão severa devido a uma hidrópsia corneana aguda no olho esquerdo. Inicialmente, a acuidade visual corrigida da paciente era de 20/80 no olho direito e de movimento de mãos no olho esquerdo. Após exame de biomicroscopia que detectou uma extensa rotura da membrana de Descemet e edema estromal, optamos por tratar esse caso com o ceratoplastia endotelial com membrana Descemet. Doze meses após o procedimento cirúrgico, percebeu-se uma melhora do edema corneano, não havia sinais de rejeição do botão óptico e a acuidade visual corrigida da paciente era de 20/50 no olho afetado.

Ophthalmological findings in infants with microcephaly and presumable intra-uterus Zika virus infection / Achados oftalmológicos em lactentes com microcefalia e infecção presumida pelo vírus Zika

ABSTRACT Purpose: In 2015, a twenty-fold increase in the prevalence of microcephaly in Brazil was reported, and the Ministry of Health associated this abnormal prevalence with the maternal-fetal Zika virus (ZIKV) transmission. Methods: We assessed the ophthalmological findings of ten mothers and their infants that had been clinically diagnosed with ZIKV-related microcephaly and presented ocular abnormalities, born from May to December 2015. Results: Seven mothers (70.0%) referred symptoms during pregnancy (malaise, rash and arthralgia), of which six (85.7%) were in the first trimester. At the time of exam, no ophthalmological abnormalities were identified in the mothers and they did not report ocular symptoms during pregnancy. Serology was negative in all infants for Toxoplasmosis, Rubella, Cytomegalovirus, Syphilis and Human Immunodeficiency Viruses. Ocular findings included macular alterations (gross pigment mottling and/or chorioretinal atrophy) in fifteen eyes (75.0%), and optic nerve abnormalities (hypoplasia with double-ring sign, pallor, and/or increased cup-to-disk ratio) in nine eyes (45.0%). Conclusions: Patients presented normal anterior segment and important macular and optic nerve abnormalities. Further studies will assess the visual significance of these alterations.

RESUMO Introdução: No ano de 2015, foi identificado no Brasil um aumento da prevalência de microcefalia em vinte vezes. Esta malformação foi associada pelo Ministério da Saúde à transmissão vertical do Zika vírus (ZIKV). Método: Investigamos dez lactentes com diagnóstico clínico presumido de microcefalia relacionada à ZIKV, que apresentavam anormalidades oculares, nascidos entre maio e dezembro de 2015. Resultados: Sete mães (70,0%) relataram sintomas (mal-estar, rash e artralgia) durante a gestação, sendo seis (85,7%) no primeiro trimestre. No dia da avaliação nenhuma alteração ocular foi identificada nas mães e elas não relataram sintomas oculares durante a gestação. Sorologia foi negativa para toxoplasmose, rubéola, citomegalovírus, sífilis e vírus da imunodeficiência adquirida (HIV) em todos os lactentes. Os achados oculares incluíram alterações maculares (depósito pigmentar grosseiro e/ou atrofia coriorretiniana) em 15 olhos (75,0%) e alterações do nervo óptico (hipoplasia do disco com sinal do duplo anel, palidez e/ou aumento da escavação papilar) em nove olhos (45,0%). Conclusões: Os pacientes apresentaram segmento anterior normal e importantes e anormalidades maculares e do nervo óptico. Estudos futuros vão avaliar a importância destas alterações visuais.

Teratogen exposure and congenital ocular abnormalities in Brazilian patients with Möbius sequence / Exposição à teratógenos e anormalidades oculares congênitas em pacientes brasileiros portadores da sequência de Möbius

Purpose: To assess the sociodemographic profiles, teratogen exposures, and ocular congenital abnormalities in Brazilian patients with Möbius sequence. Method: Forty-four patients were recruited from the Brazilian Möbius Sequence Society. This cross-section comprised 41 patients (age, mean ± standard deviation, 9.0 ± 5.5 years) who fulfilled the inclusion criteria. The parent or caregiver answered a questionnaire regarding sociodemographic data and pregnancy history. Patients underwent ophthalmological assessments. They were subdivided into groups according to misoprostol exposure during pregnancy, and the two groups were compared. Results: Mothers/caregivers reported unplanned pregnancies in 36 (88%) cases. Of these, 19 (53%) used misoprostol during their first trimesters. A stable marital status tended to be more frequent in the unexposed group (P=0.051). Incomplete elementary school education was reported by two (11%) mothers in the exposed group and by three (14%) mothers in the unexposed group (P=0.538). The mothers' gestational exposures to cocaine, marijuana, alcohol, and cigarettes were similar in both groups (P=0.297, P=0.297, P=0.428, and P=0.444, respectively). One (5%) case of Rubella infection during pregnancy was found in the unexposed group. The main malformations in the exposed and unexposed groups were the following: strabismus (72% and 77%, respectively), lack of emotional tearing (47% and 36%, respectively), and lagophthalmos (32% and 41%, respectively). Conclusion: Stable marital statuses tended to be more frequent among mothers that did not take misoprostol during pregnancy. Exposures to other teratogens and the main ocular abnormalities were similar in both groups. .

Objetivo: Descrever o perfil sóciodemográfico, exposição à teratógenos e anormalidades oculares congênitas em pacientes brasileiros portadores da sequência de Möbius Método: Quarenta e quatro pacientes recrutados da Sociedade Brasileira de Sequência de Möbius foram examinados. Este estudo transversal incluiu 41 pacientes que preencheram os critérios de inclusão do estudo (média das idades: 9,0 ± 5,5 anos). Mãe/responsável dos pacientes responderam a um questionário sobre perfil sóciodemográfico e história gestacional. Foi realizado exame oftalmológico de todos os pacientes. Eles foram agrupados em dois grupos de acordo com a exposição ao misoprostol durante a gestação e seus dados foram comparados. Resultados: Mães/responsáveis referiram gravidez indesejada em 36 (88%) dos casos. Destas, 19 (53%) fizeram uso de misoprostol no primeiro trimestre de gestação. Houve uma tendência do grupo de mães não expostas ao misoprostol de terem um estado civil estável (P=0,051). Duas (11%) mães do grupo de expostas ao misoprostol relataram primeiro grau incompleto e três (14%) do grupo de não expostas (P=0,538). A exposição das mães à cocaína, maconha, álcool e cigarro foi similar em ambos os grupos (P=0,297, P=0,297, P=0,428, P=0,444, respectivamente). Houve um caso (5%) de Rubéola no grupo de mães não expostas. As principais malformações associadas nos pacientes expostos e não expostos foram, respectivamente: estrabismo (72% e 77%), e diminuição da lágrima emocional (47% e 36%) e lagoftalmia (32% and 41%). Conclusão: Estado civil estável foi mais frequente em mães que não fizeram uso de misoprostol durante a gestação. Exposição à outros ...
