ABSTRACT
ABSTRACT This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye. The patient underwent therapeutic keratoplasty the next day. Orbital reconstruction with costochondral graft and shunt revision of the intracranial hypotension were performed the next month to prevent further progression.
RESUMO Este relato de caso descreve as características clínicas e o manejo cirúrgico de um paciente que teve perfuração da córnea devido à enoftalmia grave consistente com a "síndrome do cérebro silencioso". Um homem de 27 anos com história de hidrocefalia congênita e derivação ventrículo-peritoneal foi encaminhado com queixas de "afundamento dos globos oculares" e diminuição progressiva da visão no olho esquerdo. O exame revelou enoftalmo bilateral importante, além de perfuração superonasal da córnea com prolapso iriano no olho esquerdo. A paciente foi submetida à ceratoplastia terapêutica no dia seguinte. Foi realizado no mês seguinte a reconstrução da órbita com enxerto costocondral e revisão do shunt para evitar progressão e piora do caso.

ABSTRACT Purpose: The purpose of the present work is to measure the interocular upper lid contour symmetry using a new method of lid contour quantification. Methods: The Bézier curve tool of the Image J software was used to extract the right and left upper eyelid contours of 75 normal subjects. Inter-observer variability of 29 right lid contours obtained by two independent observers was estimated using the coefficient of overlap of two curves and an analysis of the differences of the contour peak location. A two-way analysis of variance was used to test the mean value of the coefficient of overlap of the right and left contours in males and females and lid segments. The same analysis was performed to compare the location of the contour peak of the right and left contours. Results: The coefficient of contour overlap obtained by independent observers ranged from 93.5% to 98.8%, with a mean of 96.1% ± 1.6 SD. There was a mean difference of 0.02 mm in the location of the contour peak. Right and left contour symmetry did not differ between females and males and was within the range of the method variability for contour overlap and location of the contour peak. Conclusions: The upper eyelid contour is highly symmetrical. Bézier lines allow a quick and fast quantification of the lid contour, with a mean inter-observer variability of 3.9%.
RESUMO Objetivo: O objetivo do presente estudo é mensurar a simetria interocular do contorno da pálpebra superior por meio de um novo método de quantificação de contorno palpebral com curvas de Bézier. Métodos: A ferramenta de curva de Bézier do software ImageJ foi utilizada para extrair os contornos palpebrais direito e esquerdo de 75 sujeitos normais. A variabilidade interobservador de 29 contornos palpebrais do olho direito obtidos por dois observadores diferentes foi estimada pelo coeficiente de superposição de duas curvas e pela análise das diferenças das posições do pico do contorno. Análise de variância de dois fatores foi empregada para testar a média do coeficiente de superposição entre os contornos direito e esquerdo quanto ao sexo e segmento palpebral. A mesma análise foi utilizada para comparar a localização do pico do contorno dos olhos direito e esquerdo. Resultados: O coeficiente de superposição obtidos por observadores independentes variou ente 93,5% e 98,8% com média de 96,1% ± 1,6 DP. A diferença das médias da localização do pico do contorno palpebral foi de 0,02 mm. A simetria entre os contornos dos olhos direito e esquerdo não diferiu entre o sexo feminino e masculino e esteve na faixa de variabilidade do método para o coeficiente de superposição e localização do pico do contorno. Conclusões: O contorno da pálpebra superior é altamente simétrico. As linhas Bézier permitem uma rápida e prática quantificação do contorno palpebral com uma média de variabilidade interobservador de 3,9%.

A gestação e o puerpério são períodos da vida da mulher que necessitam ser avaliados com atenção especial, pois envolvem inúmeras alterações físicas, hormonais, e, sobretudo psíquicas e de inserção social. Essas refletem diretamente na saúde mental das pacientes e em suas funções e cuidados maternos necessários ao bebê, podendo repercutir de maneira negativa no desenvolvimento físico e emocional de seus filhos.
