RESUMO

ABSTRACT Monkeypox disease is a viral zoonosis with symptoms similar to those seen in the past in smallpox (variola), although clinically less severe. Following the eradication of smallpox in 1980 and the subsequent cessation of smallpox vaccination, monkeypox has emerged as the most important orthopoxvirus from a public health standpoint. Monkeypox virus occurs primarily in central and western Africa, often in tropical forests, and has increasingly manifested in urban areas. Animal hosts include various rodents and nonhuman primates. We report the case of a patient with monkeypox disease who developed ocular complaints (eye discomfort and conjunctivitis) and had detectable conjunctival lesions on biomicroscopy and fluorescein testing. Its ophthalmological manifestations are still poorly known.


RESUMO Varíola do Macaco é uma zoonose viral com sintomas semelhantes aos observados no passado em pacientes com Varíola, embora seja clinicamente menos grave. Com a erradicação da varíola em 1980 e a subsequente cessação da vacinação contra a varíola, a varíola dos macacos emergiu como o ortopoxvírus mais importante em saúde pública. O vírus monkeypox ocorre principalmente na África central e ocidental, muitas vezes nas proximidades de florestas tropicais, e tem se manifestado cada vez mais em áreas urbanas. Os hospedeiros animais incluem uma variedade de roedores e primatas não humanos. O presente estudo relata o caso de um paciente com Monkeypox que evoluiu com queixa oftalmológica de desconforto ocular e conjuntivite e, à biomicroscopia e teste da fluoresceína, detecção de lesões conjuntivais. Alterações oftalmológicas da doença são, ainda, pouco conhecidas.

RESUMO

OBJECTIVES: To compare ocular surface changes induced via glaucoma treatment in patients using fixed combinations of prostaglandin analogues (travoprost, latanoprost and bimatoprost) with 0.5% timolol maleate METHODS: A prospective, multicenter, randomized, parallel group, single-blind clinical trial was performed in 33 patients with ocular hypertension or open angle glaucoma who had not been previously treated. The ocular surface was evaluated prior to and three months after treatment, with a daily drop instillation of one of the three medications. The main outcome measurements included the tear film break-up time, Schirmer's test, Lissamine green staining, the Ocular Surface Disease Index questionnaire, impression cytology using HE and PAS and immunocytochemistry for interleukin-6 and HLA-DR. Ensaiosclinicos.gov.br: UTN - U1111-1129-2872 RESULTS: All of the drugs induced a significant reduction in intraocular pressure. Decreases in the Schirmer's test results were observed with all of the drugs. Decreases in tear-film break-up time were noted with travoprost/timolol and latanoprost/timolol. An increase in the Lissamine green score was noted with travoprost/timolol and bimatoprost/timolol. The Ocular Surface Disease Index score increased after treatment in the travoprost/timolol group. Impression cytology revealed a significant difference in cell-to-cell contact in the same group, an increase in cellularity in all of the groups and an increase in the number of goblet cells in all of the groups. The fixed combinations induced an increase in IL-6 expression in the travoprost/timolol group, in which there was also an increase in HLA-DR expression. CONCLUSIONS: All of the fixed combinations induced a significant reduction in intraocular pressure, and the travoprost/timolol group showed increased expression of the inflammatory markers HLA-DR and interleukin-6. All three tested medications resulted in some degree of deterioration in the ocular surface after three months of glaucoma treatment.

RESUMO

PURPOSE: To report the results of Descemet stripping endothelial keratoplasty (DSEK) using the TAN EndoGlideTM device to facilitate the insertion of the endothelial membrane. METHODS: Prospective clinical study that included nine patients presenting corneal edema secondary to endothelial dysfunction. Best corrected visual acuity, refraction, central corneal thickness, endothelial cell density and complications were analyzed after a six-month follow-up. RESULTS: There was a significant improvement in the corneal edema and visual acuity in 7 patients (77.78%). The best corrected visual acuity ranged between 20/40 and 20/200. The average density of endothelial cells in six months varied between 1,305 cells/mm² and 2,346 cells/mm² with an average loss of 33.14% cells. Detachment of part of the graft was observed in one eye (11.11%) and primary failure of the endothelial transplantation occurred in 2 eyes (22.22%). CONCLUSION: The device TAN EndoGlideTM facilitates the introduction of the graft in Descemet stripping endothelial keratoplasty.

RESUMO

A Síndrome de Urrets-Zavalia apresenta achados oculares bem descritos, porém sua fisiopatologia ainda é incerta. A isquemia iriana é o mecanismo proposto mais comum. Descrevemos dois casos submetidos à ceratoplastia lamelar profunda (CLP) realizadas pelo mesmo cirugião que desenvolveram a síndrome. No primeiro caso, a indicação cirúrgica foi para o tratamento de opacidade corneana e, no segundo, para o de ceratocone. No pós-operatório, ambos os pacientes evoluíram com pupila dilatada fixa que não regrediu totalmente apesar do tratamento administrado.


The Urrets-Zavalia Syndrome presents well described ocular findings, even though its physiopathology is still unsure. Iris ischemia is the most common proposing mechanism. We describe two cases that underwent deep lamellar keratoplasty (DLK) performed by the same surgeon and developed the syndrome. In the first case, the surgical indication was for corneal opacity treatment and, in the second case, for keratoconus treatment. During the post-operatory, both patients developed fixed dilated pupil, which didn't regress completely inspite of the onset treatment.

RESUMO

OBJETIVO: Relatar os resultados da ceratoplastia endotelial com desnudamento da Descemet (DSEK) utilizando o dispositivo TAN EndoGlideTM para facilitar a introdução da membrana endotelial. MÉTODOS: Série de casos consecutivos, prospectiva. Foram incluídos 9 pacientes com edema corneano secundário à disfunção endotelial. Melhor acuidade visual corrigida, refração, astigmatismo ceratométrico, espessura corneana central, densidade das células endoteliais e complicações foram analisadas após seguimento de seis meses. RESULTADOS: Houve melhora do edema de córnea e da visão em 7 pacientes (77,78 por cento). A melhor acuidade visual corrigida ficou entre 20/40 e 20/200. A densidade endotelial média após 6 meses variou entre 1.305 céls/mm² e 2.346 céls/mm² com média de perda de 33,14 por cento. Desprendimento de parte do enxerto ocorreu em 1 olho (11,11 por cento), falência primária do transplante endotelial em 2 olhos (22,22 por cento). CONCLUSÃO: O dispositivo TAN EndoGlideTM facilita a introdução do enxerto na ceratoplastia endotelial com desnudamento da Descemet.
