ABSTRACT

Determinar la prevalencia del error de refracción (RE) como causa en los ojos en los niños en niños de esta edad (6-12 años) en la ciudad de Sulaimania. El estudio de tasa de prevalencia entre los pacientes que asisten al Shahed Dr. Aso Eye Hospital para el período del 1 de octubre de 2008 al 1 de junio de 2009. Un total de 116 niños (6-12 años) asisten al departamento de entrecerrares durante aproximadamente 8 meses. El estudio incluyó ambos sexos, eran niños de 55 años y niñas 61. Se sometieron a un examen ocular completo. Encontramos que (72) pacientes (62.02 %) tenían un error de refracción, incluyen: 33 pacientes (45.9 %) = hipermetropia (H); 22 pacientes (29.16%) = miopía [m]; 18 pacientes (24.3%) astigmatismo (AST.); 4 mixtos; 6 h-as. y 8 m-as. En conclusiones, la causa más frecuente del entrecerrar de la infancia a este ancho [6-12 años) es el error refractivo, mientras que las otras causas en su conjunto constituyen solo 1/3 de las causas, y el error de refracción más común es la hipermetropía


To determine the prevalence of refractive error (RE) as a cause in squinted in children in this aged (6-12 years) in Sulaimania city. The prevalence rate study among patient attending Shahed Dr. Aso eye hospital for the period from 1st October 2008 - 1st June 2009. A total of 116 children ( 6-12 years) attending squint department for about 8 months. The study included both sexes, were boys 55 and girls 61. Underwent full ocular examination. We found that (72) patients (62.02%) had refractive error, include: 33 patients (45.9 %) = Hypermetropia (H); 22 patients (29.16%) = Myopia [M]; 18 patients (24.3%) Astigmatism (Ast.); 4 mixed; 6 H-Ast. and 8 M-Ast. In conclusions, the most prevalent cause of childhood squint at this aged [6-12 years) is refractive error while the other causes as a whole constitute only 1/3 of the causes, and most common refractive error is hypermetropia

ABSTRACT

OBJETIVO: Analisar o segmento anterior com aparelho de câmera rotatória de Scheimpflug (Pentacam®) em candidatos à cirurgia refrativa, estabelecendo o padrão de variabilidade do volume corneano, do volume e da profundidade da câmara anterior e da paquimetria óptica nesta população. MÉTODOS: Estudo retrospectivo de 297 olhos (149 pacientes) que foram examinados com Pentacam®. Os pacientes foram divididos conforme o equivalente esférico em míopes (n=242 olhos) e hipermétropes (n=55 olhos) para analisar o volume corneano, o volume e a profundidade da câmara anterior e a paquimetria óptica. RESULTADOS: No grupo dos míopes, a média do volume corneano total foi de 59,37 ± 3,51 mm³; do volume nos 3 mm de 3,87 ± 0,23 mm³, nos 5 mm de 11,31 ± 0,67 mm³, e nos 7mm de 24,30 ± 1,43 mm³; do volume da câmara anterior 198,74 ± 32,40 mm³; da profundidade da câmara anterior 3,19 ± 0,28 mm e da paquimetria óptica 533,33 ± 33,47 mm. No grupo dos hipermétropes, a média do volume corneano total foi de 60,77 ± 3,31 mm³, do volume nos 3 mm de 4,01 ± 0,20 mm³, nos 5 mm de 11,73 ± 0,58 mm³, e nos 7 mm de 25,09 ± 1,21 mm³; do volume da câmara anterior 146,61 ± 32,86 mm³; da profundidade da câmara anterior 2,76 ± 0,38 mm e da paquimetria de 550,52 ± 29,49 mm. A diferença entre os grupos foi significativa para todas as variáveis (p<0,05). CONCLUSÃO: Concluímos nesta amostra, por meio da análise pelo Pentacam®, que os olhos míopes apresentaram menor média de volume corneano e paquimetria óptica, e maior profundidade e volume de câmara anterior em relação aos hipermétropes.


PURPOSE: To analyze the anterior segment of refractive surgery candidates and establish the variability pattern in this population regarding corneal volume, anterior chamber volume and depth and corneal thickness, using the noncontact three dimensional analyzer Pentacam®. METHODS: A retrospective study of 297 eyes of 149 patients was conducted using Pentacam®. According to the spherical equivalent value two groups were created, myopia (n=242 eyes) and hyperopia (n=55 eyes), to analyze the variables of corneal volume, anterior chamber volume and depth and corneal thickness. RESULTS: The mean values of the myopia group were: corneal total volume 59.37 ± 3.51mm³, corneal volume at 3 mm 3.87 ± 0.23 mm³, at 5 mm 11.31 ± 0.67 mm³, and at 7 mm 24.30 ± 1.43 mm³, anterior chamber volume 198.74 ± 32.40 mm³, anterior chamber depth 3.19 ± 0.28 mm and corneal thickness 533.33 ± 33.47 mm. In the hyperopia group, the mean total corneal volume was 60.77 ± 3.31 mm³, corneal volume at 3 mm from the apex was 4.01 ± 0.20 mm³, at 5 mm was 11.73 ± 0.58 mm³, and at 7 mm was 25.09 ± 1.21 mm³, the anterior chamber volume was 146.61 ± 32.86 mm³, the anterior chamber depth was 2.76 ± 0.38 mm and the corneal thickness was 550.52 ± 29.49 mm. The difference between the groups was significant for all variables (p<0.05). CONCLUSION: We observed in this study that patients with myopia had lesser mean corneal volume and pachymetry, and greater anterior chamber depth and volume compared with hyperopic patients.
