Anterior lamellar corneoscleral keratoplasty for the management of corneal thinning following treatment with mitomycin-C and interferon to treat highly suspected ocular surface squamous neoplasia: a case report

ABSTRACT A patient presented with corneoscleral thinning five months after the treatment of suspected ocular squamous surface neoplasia with mitomycin-C and interferon. For tectonic and aesthetic purposes, we decided to perform lamellar corneoscleral transplantation. The approach used established new tectonic support and corneal homeostasis. This technique might be an option in similar cases.

Clinical, epidemiological, and care profile of hospitalized patients with retinoblastoma in Brazil

ABSTRACT Purpose: To describe the epidemiological and clinical profile of hospitalized patients with retinoblastoma in Brazil. Methods: Using data from the Hospital Cancer Registry of the Instituto Nacional de Câncer, patients with the morphological codes of retinoblastoma who were diagnosed between 2000 to 2018, aged 0-19 years, and followed up in registered hospitals (analytical cases) were selected. The relative and absolute frequencies of demographic, clinical, diagnostic, therapeutic, and outcome variables were described. Hospital performance indicators were calculated and compared between hospitals qualified and not qualified to treat pediatric oncology cases and between hospitals with different case volumes (<20, 20-75, >75 cases). Results: Of the 2,269 identified analytical cases from 86 institutions, 48% were from the Southeast, 54% were male, and 66% were aged <4 years. The proportion of missing data (NA) was too high for several variables. Approximately 84% of the patients were from the public health system, 40% had a positive family history, and 88% had unilateral involvement. The first treatment included surgery in 58.3% of the patients (NA=2), Approximately 36.6% of these patients achieved complete remission, 10.8% achieved partial remission, and 12.7% died (NA=59%). Hospital performance indicators were within the target in >90% of the patients. The median time between the first appointment and diagnosis (6 days, interquartile range [IQR] 1-14) was significantly lower and the median time to death was longer (343 days, IQR, 212-539) in high-volume hospitals (>75 cases) than in medium- and low-volume hospitals. Conclusions: Despite the high proportion of missing data, we found that the delay in diagnosis is due to prehospital factors. Additionally, there is a need for educational programs for healthcare professionals and families that emphasize early identification and referral to specialized centers. Future studies should focus on the impact of Hospital Cancer Registry data completeness on outcomes, causes of delay in diagnosis, regional inequalities, and barriers to accessing specialized services.

New requirements and key points for review for research related to health information data in the Measures of Ethical Review of Life Sciences and Medical Research Involving Humans / 中国医学伦理学

To further standardize the ethical review of life science and medical research involving humans， the National Health Commission， the Ministry of Education， the Ministry of Science and Technology， and the State Administration of Traditional Chinese Medicine jointly issued the Measures of the Ethical Review of Life Science and Medical Research Involving Humans in 2023. The provisions concerning research related to health information data within it include： emphasizing the protection of personal information and privacy rights， personal information can only be collected， stored， and used under the premise that research participants know and permit， and must not be disclosed to third-party without the authorization of research participants； the ethical committee should focus on reviewing the adequacy of confidentiality measures of personal information； for research that provides information and data or cooperation with external organizations， it is necessary to fully understand the research， conduct a full ethical review， and clarify the use， processing， and disposal after completion of information data through an agreement. The research institutions should improve the information data governance and supervision system in conjunction with the key points of information data management in the new regulations. The initial ethical review should focus on the risk-benefit ratio of the research， the reasonableness of the informed consent procedure， the feasibility of the opt-out procedure， the protection measures for the privacy of the research participants， and the data management capability of the research team. The knowledge training of researchers should be strengthened， policy advisory services should be provided for them， and even a unified information data management platform should be built for them from the overall level of research institutions. The ethical follow-up review emphasizes whether the researchers continue to protect the participant’s right to independent information or personal information， and privacy. It is believed that through a series of governance measures， the health information data of research participants in China will be better protected， thus safeguarding their legitimate rights and interests.

Simultaneous unilateral central retinal vein occlusion and branch retinal artery occlusion after Coronavirus Disease 2019 (COVID-19) mRNA vaccine / Oclusão unilateral simultânea da veia retiniana central e artéria retiniana ramificada após vacina mRNA COVID-19

ABSTRACT A 51-year-old non-obese woman presented with a one-week history of progressive blurry vision within the inferior visual field of her left eye. Her only relevant past medical history was long-standing hypothyroidism and recent vaccination against Coronavirus Disease 2019 (COVID-19) with an mRNA vaccine 12 days before the onset of symptoms. At examination, the anterior segment was unremarkable, but the retinal fundus revealed a central retinal vein occlusion associated with a branch retinal artery occlusion of the superior temporal branch in her left eye. Ancillary tests to rule out thrombophilia, hyperviscosity, hypercoagulability, or inflammation were negative. Ultrasound tests were also negative for a cardiac or carotid origin of the branch retinal artery occlusion. At two-month follow-up, no new retinal vascular occlusive events were observed. Although the best-corrected visual acuity at presentation was 8/10 in the left eye, the final best-corrected visual acuity remained 3/10.

RESUMO Uma mulher de 51 anos, não obesa, apresentou história de uma semana de visão embaçada progressiva no campo visual inferior do olho esquerdo. Seu único histórico médico anterior relevante era hipotireoidismo de longa data e uma recente vacinação contra a Doença de Coronavírus 2019 (COVID-19), com vacina de mRNA, 12 dias antes do início dos sintomas. O exame mostrou segmento anterior normal, mas o fundo da retina revelou uma oclusão da veia central da retina associada a uma oclusão de ramo arterial da retina do ramo temporal superior no olho esquerdo. Testes auxiliares para descartar trombofilia, hiperviscosidade, hipercoagulabilidade ou inflamação apresentaram resultados negativos. Testes de ultrassom também foram negativos quanto a uma origem cardíaca ou da carótida da oclusão do ramo da artéria da retina. Após dois meses de acompanhamento, nenhum novo evento vascular oclusivo retiniano foi observado. Embora, a acuidade visual melhor corrigida na apresentação tenha sido de 8/10 no olho esquerdo, a acuidade visual final melhor corrigida permaneceu em 3/10.

Mycobacterium abscessus keratitis after LASIK surgery / Ceratite por Mycobacterium abscessus após cirurgia LASIK

ABSTRACT A 33-year-old male presented with unilateral subacute infectious keratitis 4 weeks after surgery. Corneal inflammation was resistant to standard topical antibiotic regimens. During diagnostic flap lifting and sampling, the corneal flap melted and separated. Through flap lifting, corneal scraping, microbiological diagnosis of atypical mycobacteria, and treatment with topical fortified amikacin, clarithromycin, and systemic clarithromycin, clinical improvement was achieved.

RESUMO Paciente do sexo masculino, 33 anos, apresentou ceratite infecciosa subaguda unilateral 4 semanas após a cirurgia. A inflamação da córnea foi resistente aos regimes de antibióticos tópicos padrão. A aba da córnea foi derretida e seccionada durante o levantamento e amostragem para diagnóstico. A melhora clínica só foi alcançada após levantamento do retalho, raspagem e diagnóstico microbiológico de micobactérias atípicas e tratamento com amicacina fortificada tópica, claritromicina e claritromicina sistêmica.

Descemet's membrane endothelial keratoplasty for primary graft failure after penetrating keratoplasty / Transplante endotelial de membrana de Descemet para falência primária após transplante penetrante

ABSTRACT Primary graft failure (PGF) is a known complication following penetrating keratoplasty (PKP). The usual approach to treat this complication is to repeat a penetrating keratoplasty. Here, we report a case of Descemet's membrane endothelial keratoplasty (DMEK) for the treatment of PGF after PKP. A patient that underwent PKP, developed PGF with persistent graft edema and very poor visual acuity despite aggressive steroid use and a proof anti-viral treatment. Three months after the initial surgery, a DMEK was performed under the PKP graft. There was progressive early corneal clearing and, by the end of the first month, the patient already had no corneal edema. Uncorrected visual acuity (UCVA) improved to 20/40 and best corrected visual acuity (BCVA) to 20/20. DMEK may be an alternative to a second PKP for the treatment of PGF. This technique is a less invasive option when compared to the standard PKP procedure.

RESUMO A falência primária do enxerto é uma complicação conhecida que pode ocorrer após o transplante penetrante de córnea. O tratamento usual dessa complicação é com um novo transplante penetrante. Apresentamos um caso em que foi usado o transplante endotelial de membrana de Descemet (DMEK - do inglês Descemet membrane endo-thelial keratoplasty) para o tratamento da falência primária após o transplante penetrante. Uma paciente submetida a transplante penetrante evoluiu com falência primária do enxerto a despeito do uso intenso de corticoide tópico e uma prova terapêutica de antivirais. Três meses após a cirurgia inicial, foi optado pela realização do transplante endotelial de membrana de Descemet sob o transplante penetrante. Houve um clareamento precoce e progressivo do enxerto com melhora importante da visão. Após um mês, a visão sem correção era de 20/40 melhorando para 20/20 com refração. O transplante endotelial de membrana de Descemet pode ser uma alternativa a um novo transplante penetrante como tratamento da falência primária.

Morphofunctional evaluation of peripapillary retinoschisis associated with myopic posterior staphyloma and hyaloid traction: does it cause peripapillary vitreoretinal traction? / Avaliação morfofuncional da retinosquise peripapilar associada ao estafloma posterior miópico e à tração hialoidea: isso causa tração vitreo-retiniana peripapilar?

ABSTRACT This case report presents the details of a 33-year-old female patient who was referred to a specialized retina service because of mild vision loss in her right eye). The patient's visual acuity was 20/25 in right eye and 20/50 in the left eye (; amblyopic); the spherical equivalent was -12.75 diopters (right eye) and -14.75 diopters (left eye). Multimodal retinal imaging showed peripapillary schisis in both the inner and outer retinal layers, grade II posterior vitreous detachment, and a tessellated fundus. Using Humphrey perimetry and MP-3 microperimetry, the functional evaluation indicated macular sensitivity within normal limits and decreased sensitivity in the peripapillary region, especially in right eye. The pattern-re versal visual evoked potential was measured. The N75 and P100 latency and amplitude in right eye were within normal values for checks of 1º. However, the amplitude was low for checks of 15′. Highly myopic patients who have posterior staphyloma that involves the optic nerve are susceptible to posterior hyaloid traction, and the resulting peripapillary vitreous traction may compromise vision.

RESUMO Este relato de caso apresenta um paciente feminino de 33 anos encaminhado para um serviço especializado de retina devido à leve perda de visão em olho direito. A acuidade visual foi de 20/25 no olho direito e 20/50 no olho esquerdo, o equivalente esférico foi de -12,75 dioptrias e -14,75 dioptrias, respectivamente. Avaliações multimodais revelaram isquese peripapilar nas camadas internas e externas da retina, descolamento vítreo posterior grau II e fundo tesselado. Avaliação funcional com perimetria Humphrey e microperimetria MP-3 revelaram sensibilidade macular normais e diminuição da sensibilidade na região peripapilar, especialmente no olho direito. Potencial visual evocado de padrão reverso apresentou no olho direito latência e amplitude N75 e P100 dentro dos valores normais para verificação de 1º. Entretanto, a amplitude foi baixa para a de 15′. Pacientes alto míopes com esfiloma posterior envolvendo o nervo óptico são suscetíveis à tração da hialoide posterior. Portanto a tração vitreopapilar resultante pode causar comprometimento da visão.

Corneal ectasia following photorefractive keratectomy: a confocal microscopic case report and literature review / Ectasia corneana após ceratectomia fotorrefrativa: relato de caso de microscopia confocal e revisão da literatura

ABSTRACT The occurrence of corneal ectasia after photorefractive keratectomy is a rare but serious complication of refractive surgery. Possible risk factors are not well assessed, but a probable reason is the failure to detect keratoconus preoperatively. In this report, we describe a case of corneal ectasia after photorefractive keratectomy in a patient who presented a suspicious tomography pattern preoperatively but had no degenerative alterations associated with pathologic keratoconus, as revealed by in vivo corneal confocal microscopy. We also review eligible case reports of post-photorefractive keratectomy ectasia to find similar characteristics.

RESUMO A ocorrência de ectasia corneana após ceratectomia fotorrefrativa é uma complicação rara, porém grave, em cirurgia refrativa. Os possíveis fatores de risco não são bem avaliados, mas a opinião atual é que a falha na detecção de ceratocone pré-operatório possa ser o principal motivo. Neste relato, descrevemos um caso de ectasia corneana após ceratectomia fotorrefrativa em paciente apresentando padrão tomográfico suspeito no pré-operatório, mas sem alterações degenerativas associadas a ceratocone patológico, conforme revelado por microscopia confocal in vivo da córnea. Além disso, revisamos, na literatura, relatos de casos elegíveis de ectasia pós-ceratectomia fotorrefrativa para encontrar características semelhantes.

Apical bleeding: a rare cause of blindness after orbital decompression / Sangramento apical: uma causa rara de cegueira pós descompressão orbitária

ABSTRACT Orbital decompression is widely performed for the management of proptosis for cosmetic and functional cases of Graves orbitopathy. The main side effects include dry eye, diplopia, and numbness. Blindness after orbital decompression is extremely rare. The mechanisms of vision loss after decompression are not well described in the literature. Considering the devastating effect and rarity of this complication, this study presented two cases of blindness after orbital decompression. In both cases, vision loss was provoked by slight bleeding in the orbital apex.

RESUMO A descompressão orbitária é uma cirurgia amplamente empregada para correção da proptose em casos cosméticos e funcionais da orbitopatia de Graves. Os principais efeitos colaterais induzidos pela descompressão são olho seco, diplopia e parestesias. Amaurose pós descompressão é uma complicação extremamente rara e cujos mecanismos são pouco discutidos na literatura. Considerando o efeito devastador representado pela perda visual e a escassez de relatos dessa complicação, os autores apresentam dois relatos de amaurose após descompressão orbitária. Nos dois casos a perda visual ocorreu devido a sangramento de pequena monta no ápice orbitário.

Primary basal cell carcinoma of the caruncle: case report and review of the literature

ABSTRACT We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

Evaluation of corneal tomography in children and adolescents without ocular or systemic allergy / Avaliação da tomografia de córnea em crianças e adolescentes sem alergia ocular ou sistêmica

ABSTRACT Purpose: To determine normal corneal tomographic parameters in children and adolescents without corneal disease or atopy diagnosis. Methods: This descriptive cross-sectional study evaluated patients aged 8-16 years who underwent a complete slit-lamp biomicroscopic examination and tomographic corneal evaluation by a dual Scheimpflug analyzer, excluding those with ocular disease (including allergic conjunctivitis) or a positive prick test for systemic atopies. Results: A total of 170 patients were evaluated, and 34 patients (68 eyes) were analyzed once the exclusion criteria were applied. The sample's mean age was 10.76 ± 2.31 years; with 19 (55.9%) men and 15 (44.1%) women. The mean keratometry in the flat meridian (Kflat), steep meridian (Ksteep), and maximum (Kmax) were 42.37 ± 1.63D, 43.53 ± 1.65D, and 43.90 ± 1.73D, respectively. The mean values for corneal asphericity (ε2) and thinnest point were 0.28 ± 0.11 and 550.20 ± 37.90 μm, respectively. The inferior-superior asymmetry ratio (I-S) and coma were 0.74 ±0.59D and 0.28 ± 0.12D, respectively. Conclusion: The knowledge of normal corneal tomographic parameters and their variation in children and adolescents without corneal disease or atopy may be useful for diagnosing keratoconus and initiating early disease treatment.

RESUMO Objetivo: Identificar parâmetros tomográficos de normalidade em córneas de crianças e adolescentes sem a presença de atopias sistêmicas e alergias oculares. Métodos: Este estudo descritivo transversal avaliou pacientes com idade entre 8 e 16 anos que foram submetidos a exame biomicroscópico completo por lâmpada de fenda e avaliação tomográfica da córnea por tomógrafo dual Scheimpflug, excluindo pacientes com doença ocular (incluindo conjuntivite alérgica) ou prick test positivo para atopias sistêmicas. Resultados: Cento e setenta pacientes foram avaliados e após cumpridos os critérios de exclusão, 34 (68 olhos) foram analisados. A média etária da amostra foi 10,76 ± 2,31 anos; 19 (55,9%) eram meninos e 15 (44,1%) meninas. A média da ceratometria em dioptrias (D) no meridiano mais plano (Kflat), mais curvo (Ksteep) e máxima (Kmax) foram 42,37 ± 1,63D, 43,53 ± 1,65D e 43,90 ± 1,73D, respectivamente. Os valores médios da asfericidade corneana (ε2) e do ponto mais fino da córnea foram 0,28 ± 0,11 e 550,20 ± 37,90 micras (μm). A assimetria corneana inferior-superior (I-S) e coma foi em média 0,74 ± 0,59D e 0,28 ± 0,12D, respectivamente. Conclusão: O conhecimento dos valores médios e sua variação de parâmetros tomográficos da córnea em crianças e adolescentes sem atopias sistêmicas ou alergias oculares pode ser útil para o diagnóstico precoce do ceratocone e o seu tratamento em estágio inicial.

Glioma of the optic nerve and chiasm: a case report / Glioma óptico-quiasmático: um relato de caso

ABSTRACT This article reports the case of an 11-year-old male patient with a history of proptosis and low progressive visual acuity in the left eye. He presented with a best corrected visual acuity of 20/25 in the right eye and light perception in the left eye. Exotropia and limitation in adduction were observed in the left eye. On automated perimetry, inferiortemporal quadrantopsia was observed in the right eye, while total scotoma was observed in the left eye. On magnetic resonance imaging, there was an expansive lesion in the left optic nerve, extending to the brainstem with chiasmatic involvement. This article aims to report a case of optic pathway glioma, as well as to discuss its clinical findings and their interconnection with the current literature.

RESUMO Este artigo relata o caso de um paciente do sexo masculino, 11 anos de idade, com história de proptose e baixa de acuidade visual progressiva. Ao exame oftalmológico apresentava melhor acuidade visual de 20/25 em olho direito e percepção de luz em olho esquerdo. Existia exotropia e limitação à adução no olho esquerdo. À campimetria automatizada, observou-se quadrantopsia temporal inferior em olho direito e escotoma total em olho esquerdo. À ressonância magnética, evidenciou-se lesão expansiva em trajeto do nervo óptico esquerdo estendendo-se até região do tronco encefálico, com acometimento quiasmático. O objetivo deste artigo é relatar o glioma de vias ópticas, bem como discutir os achados e sua interligação com a literatura atual.

Conjunctival leiomyosarcoma in a patient with xeroderma pigmentosum: 5-year follow-up without recurrence / Leiomiossarcoma da conjuntiva em paciente com xeroderma pigmentoso: acompanhamento de 5 anos sem recidivas

ABSTRACT Conjunctival leiomyosarcoma is a very rare soft tissue malignancy. Herein, we describe a conjunctival leiomyosarcoma case in a patient with another rare disease, xeroderma pigmentosum. The 27-year-old single-eyed xeroderma pigmentosum patient complained of exophytic mass covering the ocular surface in her left eye. A vascular, hemorrhagic mass covering the entire ocular surface of the left eye was identified on the examination. Thus, total mass excision surgery was performed. The pathological diagnosis was compatible with conjunctival leiomyosarcoma. Additional chemotherapy, radiotherapy, or surgery were not accepted by the patient. No recurrence or metastasis was observed during the 5-year follow-up. Both primary conjunctival leiomyosarcoma and xeroderma pigmentosum are very rare diseases. Conjunctival masses in xeroderma pigmentosum patients should be approached carefully, and histopathological examination is warranted. For conjunctival leiomyosarcoma, early diagnosis, localized, unspread disease, and complete resection provide the best prognosis.

RESUMO O leiomiossarcoma da conjuntiva é um tumor ma­ligno de tecidos moles muito raro. Aqui é descrito um caso de leiomiossarcoma da conjuntiva em um paciente com xeroderma pigmentoso, que também é uma doença rara. Um paciente de 27 anos de idade com xeroderma pigmentoso de olho único queixou-se de uma massa exofítica cobrindo a superfície ocular do olho esquerdo. Ao exame, foi observada uma massa vascular hemorrágica cobrindo toda a superfície ocular do olho esquerdo. Foi realizada uma cirurgia de excisão total dessa massa. O diagnóstico patológico foi compatível com leiomiossarcoma da conjuntiva. O paciente recusou qualquer quimioterapia, radioterapia ou cirurgia adicional. Nenhuma recidiva ou metástase foi observada durante o acompanhamento de 5 anos. Tanto o leiomiossarcoma primário da conjuntiva quanto o xeroderma pigmentoso são doenças muito raras. Massas conjuntivais em pacientes com xeroderma pigmentoso devem ser abordadas com cuidado e deve-se realizar um exame histopatológico. Para o leiomiossarcoma conjuntival, o diagnóstico precoce, uma doença localizada e não disseminada e a ressecção completa proporcionam o melhor prognóstico.

Findings of ocular examinations in healthy full-term newborns / Achados de exame ocular realizado em recém-nascidos a termo saudáveis

ABSTRACT Purpose: To assess the anterior and posterior segments of full-term neonates over a 1.5-year period. Methods: The findings of full-term neonates who underwent ophthalmological examinations between June 2019 and December 2020 were analyzed, and the results were retrospectively recorded. Results: The study comprised 2972 neonates with a mean birth week of 38.7 ± 1.2 weeks and a mean birth weight of 3235 ± 464 g. The neonates were examined on an average of 49.3 ± 18.9 postnatal days. Of the examined neonates, 185 (6.2%) showed abnormal ophthalmological findings, the most prevalent of which were retinal hemorrhage in 2.3% (n=68) and white changes in the peripheral retina in 1.9% (n=55) of the neonates. Cases of optic disc pathologies (n=20), choroidal nevus (n=10), iris-choroidal coloboma (n=5), subconjunctival hemorrhage (n=6), non-specific retinal pigmentary change (n=4), congenital cataract (n=3), posterior synechia (n=3), iris nevus (n=3), corneal opacity (n=1), choroidal coloboma (n=1), iris coloboma (n=1), buphthalmos (n=1), anophthalmos (n=1), microphthalmia (n=1), lid hemangioma (n=1), and vitreous hemorrhage (n=1) collectively accounted for approximately 2% of all neonates. Pathologies that could potentially impair vision, which were detected by ophthalmological examination, accounted for 1.2% of all neonates (n=37). Conclusion: The most prevalent finding of the ophthalmological examinations of neonates in the present study was retinal hemorrhage. Ophthalmological examinations of neonates can help in identifying diseases that may affect their vision and are curable or may lead to amblyopia in the long term.

RESUMO Objetivo: Avaliar os segmentos anterior e posterior em recém-nascidos a termo durante um período de 1,5 anos. Métodos: Foram analisados recém-nascidos a termo que tiveram os olhos examinados entre junho de 2019 e dezembro de 2020, e os resultados foram registrados retrospectivamente. Resultados: O estudo foi composto por 2.972 recém-nascidos com média de uma semana de nascimento de 38,7 ± 1,2 semanas e um peso médio ao nascer de 3235 ± 464 g. Os recém-nascidos foram examinados em média pós-natal de 49,3 ± 18,9 dias. Dos recém-nascidos, 185 (6,2%) apresentaram resultados oculares anormais. Os achados oculares anormais mais prevalentes foram hemorragia da retina em 2,3% (n=68) e alterações brancas na retina periférica em 1,9% (n=55) dos recém-nascidos. Casos de patologias de disco óptico (n=20), nevo de coroide (n=10), coloboma iris-coroide (n=5), hemorragia subconjuntival (n=6), alteração pigmentar da retina não específica (n=4), catarata congênita (n=3), Sinequia posterior (n=3), nevo da íris (n=3), opacidade da córnea (n=1), coloboma de coroide (n=1), coloboma de íris (n=1), buftalmos (n=1), anoftalmia (n=1), microftalmia (n=1), hemangioma de pálpebra (n=1) e hemorragia vítrea (n=1) contabilizaram coletivamente cerca de 2% dos recém-nascidos. As patologias que potencialmente prejudicam a visão, detectadas por exame ocular, representaram 1,2% dos recém-nascidos (n=37). Conclusão: O achado mais prevalente de exames oculares de recém-nascidos neste estudo foi hemorragia da retina. Exames oftalmológicos em recém-nascidos podem ser úteis na identificação de doenças que podem impactar a visão deles, podendo ser curáveis ou levar à ambliopia no longo prazo.

Retinal vein and artery occlusion as the first manifestation of primary antiphospholipid syndrome in a pediatric patient / Oclusão arterial e venosa como primeira manifestação da síndrome antifosfolipide primária em criança

ABSTRACT Antiphospholipid syndrome is an acquired autoimmune disease characterized by hypercoagulability associated with recurrent venous and arterial thromboembolism in the presence of antiphospholipid antibodies. Herein, we report a case of rapid sequential retinal vein and artery occlusion as the first manifestation of a primary antiphospholipid syndrome triggered by an acute Mycoplasma infection in a previously healthy 11-year-old patient. On day 1, ophthalmoscopy revealed a central retinal vein occlusion. The patient developed temporal branch retinal artery occlusion the next day. On day 3, a central retinal artery occlusion was observed. Serum lupus anticoagulant, immunoglobulin (Ig) G anticardiolipin, IgG anti-β2-glycoprotein 1 antibody, and Mycoplasma pneumoniae IgM antibody levels were increased. Thus, retinal vascular occlusions can be the first manifestation of primary antiphospholipid syndrome. Although it may not improve visual prognosis, prompt diagnosis and treatment are essential to avoid further significant morbidity.

RESUMO A síndrome antifosfolipide é uma doença autoimune adquirida caracterizada por hipercoagulabilidade associada a tromboembolismo venoso e arterial recorrente na presença de anticorpos antifosfolipídicos. Aqui, relatamos um caso clínico de oclusão sequencial de veia e artéria da retina como primeira manifestação de uma síndrome antifosfolipíde primária desen­cadeada por uma infeção aguda por Mycoplasma num paciente de 11 anos previamente saudável. No primeiro dia, a oftalmoscopia revelou uma oclusão da veia central da retina. No dia seguinte, o paciente desenvolveu uma oclusão do ramo temporal da artéria central da retina. No terceiro dia, uma oclusão da artéria central da retina foi diagnosticada. Os níveis de anticoagulante lúpico sérico, anticorpos IgG anticardiolipina e IgG anti-β2-glicoproteína 1 e anticorpos IgM para Mycoplasma pneumoniae estavam aumentados. As oclusões vasculares retinianas podem ser a primeira manifestação da síndrome antifosfolipíde primária. Apesar do prognóstico visual ser reservado, o seu diagnóstico e o tratamento imediatos são essenciais para evitar outras morbilidades associadas.

Erdheim-Chester disease with chorioretinal and orbital involvement: a case report / Doença de Erdheim-Chester com envolvimento coriorretiniano e orbitário: relato de caso

ABSTRACT A 42-year-old woman presented with bilateral proptosis, chemosis, leg pain, and vision loss. Orbital, chorioretinal, and multi-organ involvement of Erdheim-Chester disease, a rare non-Langerhans histiocytosis, with a negative BRAF mutation was diagnosed based on clinical, radiological, and pathological findings. Interferon-alpha-2a (IFNα-2a) was started, and her clinical condition improved. However, 4 months later, she had vision loss with a history of IFNα-2a cessation. The same therapy was administered, and her clinical condition improved. The Erdheim-Chester disease is a rare chronic histiocytic proliferative disease that requires a multidisciplinary approach and can be fatal if left untreated because of multisystemic involvements.

RESUMO Uma mulher de 42 anos apresentou proptose bi-lateral, quemose, dor nas pernas e perda de visão. Com base em achados clínicos, radiológicos e patológicos, foi diag-nosticada doença de Erdheim-Chester com acometimento orbitário, coriorretiniano e multiorgânico. Trata-se de uma rara histiocitose não Langerhans negativa para a mutação BRAF. Foi iniciado tratamento com interferon alfa-2a (IFNα-2a) e o quadro clínico melhorou. No entanto, quatro meses depois, a paciente apresentou perda visual após a cessação do IFNα-2a. A mesma terapia foi administrada novamente e sua condição clínica melhorou novamente. A doença de Erdheim-Chester é uma doença proliferativa histiocítica crônica rara que necessita de uma abordagem multidisciplinar e pode ser fatal se não tratada, devido a envolvimentos multissistêmicos.

Bilateral acute depigmentation of the iris (BADI) and bilateral acute iris transillumination (BAIT): A case series from a center in Brazil

ABSTRACT Bilateral acute depigmentation of the iris and bilateral acute iris transillumination (BAIT) are similar clinical entities. The former causes acute-onset depigmentation of the iris stroma without transillumination, whereas the latter causes depigmentation of the iris pigment epithelium with transillumination. The etiopathogenesis of these conditions is not yet fully understood, but the proposed causes include the use of systemic antibiotics (especially moxifloxacin) and viral triggers. We present a case series of five female patients with a mean age of 41 (32-45) years, all of whom suffered acute onset of bilateral pain and redness of the eyes after moxifloxacin use (oral or topical). It is important for ophthalmologists to be aware of the two forms of iris depigmentation since this case series suggests that SARS-CoV-2 or its empirical treatment with moxifloxacin may trigger iris depigmentation. If this is the case, clinicians will likely see increased incidences of bilateral acute depigmentation of the iris and bilateral acute iris transillumination during and after the COVID-19 pandemic.

Endogenous endophthalmitis due to Escherichia coli: a case report

ABSTRACT Endophthalmitis is a severe form of purulent inflammation caused by the infection of the intraocular tissues or fluids. This infection infrequently occurs through endogenous routes, which are often correlated with major risk factors. Escherichia coli, a gram-negative rod, can cause endophthalmitis through hematogenous spread. We here report a 59-year-old man who presented to our service with acute visual impairment in his left eye, preceded by floaters. He was taking sirolimus and azathioprine for a transplanted kidney, had undergone catheterization for bladder atresia, and had a history of recurrent E. coli urinary tract infections. On evaluation, the left eye exhibited visual acuity of hand motion, anterior chamber reaction (3+/4+), and intense vitritis (4+/4+) with white flake clusters, which prevented appropriate retinal evaluation. Pars plana vitrectomy was performed, and the culture yielded E. coli. The present case highlights the importance of identifying the signs and symptoms of infection early so that diagnosis and treatment of endophthalmitis can be promptly initiated.
