“…20 As with all ultrasound procedures, reproducibility and quality depend on the operator. The reproducibility of UBM echograms and their analysis has been studied by Yang, et al, 32 de Souza Filho et al, 33 and Spaeth et al 34 These 3 studies confirmed low interobserver and intraobserver variability and validated the method of Pavlin and Foster. 6 In our study, there was a strongly significant difference between the groups in ACD, with the posterior technique having a 55% deeper mean ACD.…”

“…Pupillary block and PIC are the most common mechanisms of primary angle closure, and they can coexist (20) . Changes in ocular dimensions with aging, especially in the anterior segment, have already been studied (21)(22) . It is assumed that the lens of these eyes is proportionally thicker than that of normal eyes, or of younger patients.…”

“…Após a obtenção das imagens, foram feitas as medidas consideradas de importância no estudo da morfometria do segmento anterior do olho, de acordo com a descrição encontrada na literatura, que são (2) : a) profundidade da câmara anterior (PCA); b) distância de contato írido-lenticular (ILCD); c) distância de abertura do ângulo a 250 e a 500 micrômetros do esporão escleral (AOD 250 e AOD 500); d) distância da faixa trabecular ao processo ciliar (TCPD); e) espessura iriana (ID1); f) distância írido-zonular (IZD). Além desses parâmetros, foram também medidas as seguintes variáveis, empregando-se técnica proposta em trabalho anterior pelos autores (11) : a) espessura escleral a 2,0 e a 3,0 mm do esporão escleral (EE2 e EE3) e b) espessura do corpo ciliar a 2,0 e a 3,0 mm do esporão escleral (ECC2 e ECC3). Cada variável de interesse foi comparada entre olhos direitos e esquerdos de acordo com o meridiano.…”
