ABSTRACT

Resumo Objetivo: Determinar a frequência da microftalmia associada à catarata congênita e sua frequência etiológica. Comparar o resultado visual após a cirurgia da catarata congênita em olhos microftálmicos, com o resultado visual obtido em olhos não microftálmicos. Método: Estudo retrospectivo de 76 pacientes portadores de microftalmia e catarata congênita, selecionados após análise de 1050 prontuários dos pacientes atendidos no ambulatório de catarata congênita da UNIFESP. A microftalmia foi determinada pela ecobiometria ultrassonica. Exames oculares e complementares foram feitos para esclarecer a causa etiológica. O resultado visual pós- operatório do Grupo I (com microftalmia) foi confrontado com o resultado visual obtido no Grupo II (sem microftalmia). Resultados: O diâmetro ântero-posterior dos olhos microftálmicos variou de 13 à 21 mm. A frequência etiológica da catarata congênita associada aos olhos microftálmicos foi assim distribuída: doenças infecciosas (55,3%); seguidos de idiopáticas (26,3%), colobomas (7,9%), hereditárias (6,6%), persistência do vítreo primário hiperplásico (2,6%) e associada à síndrome de Lenz (1,3%) .A frequência da microftalmia foi de 7,23 %. 68,3% de olhos afácicos microftálmicos atingiram visão melhor e ou igual à 20/200. Conclusão: A frequência da microftalmia associada à catarata congênita foi de 7,23%. A maior frequência etiológica ocorreu nas doenças infecciosas (55,3%), Embora os olhos microftálmicos tenham tendência para piores resultados visuais quando comparados aos não microftálmicos, nesta pesquisa os olhos microftálmicos afácicos que atingiram visão melhor ou igual a 20/200 foram de 68,3%.


Abstract Objective: To determine the frequency of microphthalmia associated with congenital cataract and its etiological frequency. Compare the result of visual acuity in aphakic microphthalmus eyes, with the visual acuity result obtained in non microphthalmus eyes. Methods: Retrospective study of 76 patients with microphthalmia and congenital cataract, selected after analysis of 1050 medical records of patients seen in congenital cataract clinic of UNIFESP. All patients underwent complete ophthalmologic examination and microphthalmia determined by ultrasound biometry. Investigations were made to clarify the etiological cause. The postoperative visual outcome of Group I (with microphthalmia) was faced with the visual results obtained in Group II (control group without microphthalmia). Results: The anteroposterior diameter of microphthalmus eyes ranged from 13 to 21 mm. The etiological frequency of microphthalmia and congenital cataract was distributed as follows: infectious diseases (55.3%), idiopathic (26.3%), colobomas (7.9%), hereditary (6.6%), persistent hyperplastic vitreous (2.6%) and linked to the Lenz's syndrome (1.3%). The visual acuity in aphakic eyes that reached better view and or equal to 20/200 was 68.3%. Conclusion: The frequency of microphthalmia associated with congenital cataract was 7.23%. The etiological occurred more frequently in infectious disease (55.3%). The aphakics eyes with microphthalmia tend to have worse visual acuity results than the eyes without microphthalmia. If we consider the visual results same and above 20/200 as successful in this search, aphakic eyes with microphthalmia that hit these indices are 68.3%.

ABSTRACT

OBJETIVO: Conhecer as lesões oculares mais frequentes encontradas em crianças expostas à toxoplasmose congênita. MÉTODOS: Trata-se de um estudo retrospectivo, a partir de uma coorte histórica, de abordagem quantitativa. Foram avaliadas crianças encaminhadas de um serviço de infectologia pediátrica e inseridas apenas aquelas com diagnóstico confirmado de toxoplasmose congênita. A avaliação oftalmológica incluiu o mapeamento de retina sequencial, sob dilatação pupilar. RESULTADOS: Das 58 crianças presumivelmente expostas ao risco de doença durante a gestação, 20 apresentaram lesões oftalmológicas ao longo do primeiro ano de vida (34 olhos). Destas, 12 estavam assintomáticas ao nascimento. Estrabismo foi registrado em 14 crianças (70 por cento). Em uma criança observou-se ptose palpebral e em outra diminuição da fenda palpebral (microftalmia). Retinocoroidite foi a complicação mais frequente, presente em todas as 20 crianças. Sete crianças apresentaram alterações unilaterais (35 por cento) e 13 crianças apresentaram alterações bilaterais (65 por cento), prevalecendo a localização no polo posterior e mácula. CONCLUSÃO: Retinocoroidite e estrabismo destacaram-se como importantes sequelas da toxoplasmose congênita.


PURPOSE: This study aimed to know the most common ocular findings in children with congenital toxoplasmosis. METHODS: This is a retrospective study carried out from a historical cohort, with a quantitative approach. We evaluated children referred to a pediatric infectious disease service and included only those with confirmed diagnosis of congenital toxoplasmosis. The ophthalmologic evaluation included regular fundus examination under pupil dilation. RESULTS: Of 58 children presumably exposed to risk of the disease during the pregnancy, 20 had ocular lesions during the first year of life (34 eyes). Of these, 12 were asymptomatic at birth. Strabismus was noted in 14 children (70 percent). In one child there was ptosis, and another had decrease in the palpebral fissure (microphthalmia). Retinochoroiditis was the most common complication, present in all 20 children. Seven children (35 percent) showed unilateral changes and 13 children showed bilateral changes (65 percent), with emphasis on the location in the posterior pole and macula. CONCLUSION: Retinochoroiditis and strabismus were outstanding as important sequelae of congenital toxoplasmosis.

ABSTRACT

PURPOSE: To describe the ocular manifestations of congenital rubella syndrome (CRS), a common cause of congenital cataracts in developing countries. METHODS: Retrospective analysis of case records of 46 sero-positive infants under 12 months of age who presented at Aravind Eye Hospital, Madurai between July 1993 and February 2001. The ocular and systemic examination details were recorded. RESULTS: Both eyes were affected in 41 (89%) patients. Cataract was present in 81 (93.1%) eyes; most of them were nuclear cataract (79, 97.5%). Other common ocular presentations included microphthalmos in 74 (85.1%) eyes, iris abnormalities in 51 (58.6%) eyes, and pigmentary retinopathy in 33 (37.9%) eyes. Cataract, microphthalmos and iris hypoplasia was a common combination present in 49 (56.3%) eyes. Systemic manifestations included cardiac anomalies in 23 (50%) and neurological anomalies in 16 (34%) children. Multi-system involvement was present in 32 (70%) children. Low birth weight (below 2 kg) was seen in 30% infants. CONCLUSION: CRS may present with a wide spectrum of ocular and systemic findings and requires a high index of suspicion for diagnosis. Any sick infant with unilateral or bilateral congenital cataract should be investigated thoroughly for CRS.

ABSTRACT

En un período de cuatro años se revisan 80 casos de leucocoria, encontrándose dos casos anatomopatológicos de gliosis masiva de retina. Se efectúa estudios de microscopía electrónica y estudio inmunohistoquímico. Los hallazgos demostraron que la masa pseudotumoral se debía a proliferación de células fusiformes de citoplasma eosinofílico fibrilar y que el método de la peroxidasa antiperoxidasa confirmó como tejido glial. La microscopía electrónica demostró un patrón similar al presentado por las células de Muller
