ABSTRACT

PURPOSE: To investigate the contribution of the individual ocular components, i.e. anterior chamber depth, lens thickness and vitreous chamber depth, to total axial length in patients with esotropic amblyopia. METHODS: The study population consisted of 74 children, aged between 5 and 8 years: thirty-seven patients with esotropic amblyopia and 37 healthy volunteers (control group). The participants underwent a comprehensive ophthalmological examination, including cycloplegic refraction and A-scan ultrasonography. Anterior chamber depth, lens thickness, vitreous chamber depth and total axial length were recorded. Paired Student's t-tests were used to compare biometric measurements between amblyopic eyes and their fellow eyes and between right and left eyes in the control group. To evaluate the contribution of the ocular components to the total axial length, we report the individual components as a percentage of total axial length. RESULTS: The comparison between amblyopic and fellow eyes regarding the individual contribution from ocular components to the total axial length revealed greater contribution from lens thickness (P=0.001) and smaller contribution from vitreous chamber depth (P=0.001) in amblyopic eyes, despite similar contribution from anterior chamber depth (P=0.434). The comparison between right and left eyes in the control group showed similar contributions from anterior chamber depth (P=0.620), lens thickness (P=0.721), and vitreous chamber depth (P=0.483). CONCLUSIONS: This study shows differences between amblyopic and non-amblyopic eyes when the total axial length is broken down into the individual contribution from the ocular components.


OBJETIVO: Investigar a contribuição individual da profundidade da câmara anterior, da espessura do cristalino e da profundidade da câmara vítrea para o comprimento axial total em pacientes com ambliopia por esotropia. MÉTODOS: Foram incluídas 74 crianças com idade entre 5 e 8 anos, sendo 37 pacientes com ambliopia por esotropia e 37 voluntários sadios (grupo controle). Foi realizado exame oftalmológico completo, incluindo refração sob cicloplegia e ultrassonografia modo A. Foram registrados profundidade da câmara anterior, espessura do cristalino, profundidade da câmara vítrea e comprimento axial total. A contribuição individual de cada componente para o comprimento axial total foi relatada como valor porcentual e teste t de Student pareado foi utilizado para a comparação entre olho amblíope e olho contralateral e entre olho direito e esquerdo no grupo controle. RESULTADOS: Olhos amblíopes, quando comparados aos olhos contralaterais, apresentaram maior contribuição da espessura do cristalino (P=0,001), menor contribuição da profundidade da câmara vítrea (P=0,001) e contribuição semelhante da profundidade da câmara anterior (P=0,434) para o comprimento axial total. A comparação entre olho direito e olho esquerdo no grupo controle mostrou contribuições semelhantes da profundidade da câmara anterior (p=0,620), da espessura do cristalino (P=0,721) e da profundidade da câmara vítrea (P=0,483) para o comprimento axial total. CONCLUSÕES: Este estudo mostrou diferenças entre olhos amblíopes e não amblíopes quando o comprimento axial total é dividido nas contribuições individuais dos seus componentes.

ABSTRACT

Os autores relatam o caso de uma paciente que apresentou quadro reincidente de esotropia aguda e diplopia durante o período gestacional. Não havia história de trauma ou qualquer alteração sistêmica, excetuando-se a gravidez. Tratamento oclusivo alternado foi instituído, e após o parto houve remissão espontânea dos sinais e sintomas.


The authors report a case of a female patient who presented, for the second time, diplopia and acute esotropia during pregnancy. There was no trauma involved neither was systemic disease. The patient was treated with conventional occlusion, and, soon after delivery, the squint was resolved.

ABSTRACT

Objetivo: Existen algunas esotropias congénitas (ET.C.) que presentan una evolución espontánea de la esodesviación hacia una exotropía, sin que medie tratamiento médico-quirúrgico alguno. El propósito de este trabajo es determinar qué porcentaje de ET.C. presentan esta evolución espontánea y sus características clínicas. Método: Estudio retrospectivo de pacientes portadores de ET.C visualmente adultos que no han recibido tratamiento médico-quirúrgico. Fueron seleccionados 86 pacientes. Resultados: De los 86 pacientes 14 evolucionaron espontáneamente desde la esotropia hacia la exo, estando 7 ortotrópicos y 7 exotrópicos. Conclusión: El 16.27 por ciento de las E T. C. evolucionarían espontáneamente a la exodesviación. Sus características clínicas permiten alertar cuáles pacientes podrían seguir esta tendencia y postergar una eventual cirugía.


Purpose: Some congenital esotropias progress spontaneously to an exodeviation, with no medical or surgical intervention. Our purpose is to asses this phenomenon and its clinical characteristics. Method: Retrospective study of 86 visually mature, untreated, congenital esotropia patients. Results: Out of 86 cases, 14 spontaneously evolutioned from esotropia to exo, being 7 ortotropic and 7 exotropic. Conclusion: 16.27 percent of congenital esotropias spontaneously evolutioned to exodesviations. Their clinical characteristics allows a recognition of cases potentially following this trend, and eventually delay surgery in this patients.

ABSTRACT

PURPOSE: To describe the clinical features of Duane's retraction syndrome (DRS) in Korean patients. METHODS: We retrospectively analyzed the 78 DRS cases that presented to our department between 1995 and 2004. The clinical features investigated included sex distribution, laterality, type of presentation, deviation in primary position, anomalous vertical movements, face turn, amblyopia and anisometropia. RESULTS: There were 38 (48.7%) affected males and 40 (51.3%) females. Left eye predominance (83.3%) was observed, as was type I presentation (85.9%). Orthotropia was found to be the most common primary position in 46 cases (59.0%). Face turn in unilateral DRS was noted in 13 patients (17.1%). There were 6 cases (7.7%) with anisometropia and 4 (5.1%) with amblyopia. CONCLUSIONS: The clinical manifestations of DRS in our study were different from those of equivalent Caucasian studies yet similar to those previously reported for Asian groups. Racial and regional differences were noted, for which further research is needed to elaborate the reasons and mechanisms.

ABSTRACT

Segundo a clássica teoria de Helmholtz, a posiçäo de repouso do sistema acomodativo é o infinito. Esse modelo näo é mais válido, visto que para a maioria das pessoas a posiçäo de repouso do sistema é intermediária. O presente trabalho discute algumas implicaçöes clínicas dessa nova abordagem, especialmente uma possível relaçäo entre a acomodaçäo tônica e deterioraçäo das esotropias acomodativas

ABSTRACT

Se hace un resumen del tratamiento ortóptico del estrabismo congénito en niños desde los 6 meses de edad. Se muestra las distintas formas de oclusión. La revisión de historias clínicas demuestra que las cirugías tempranas no garantizan al paciente visión binocular ni estereopsis. El seguimiento ortóptico postquirúrgico es ideal. Con su variedad de formas de tratamiento ayuda a complementar el éxito de la cirugía y mantener en lo posible una buena agudeza visual en ambos ojos
