ABSTRACT

Purpose:

To investigate the effects of topically applied 1% cyclopentolate hydrochloride on anterior segment parameters obtained with a Pentacam rotating Scheimpflug camera in healthy young adults.

Methods:

Anterior segment analyses of 25 eyes from 25 young adults (Group 1), before and after 45 min of 1% cyclopentolate hydrochloride application, were performed. For a control group (cycloplegia-free, Group 2), 24 eyes of 24 age- and sex-matched healthy cases were evaluated twice at 45 min intervals. The results obtained from the groups were compared statistically.

Results:

The mean ages of the groups were 23.04 ± 3.42 (range, 18-29) and 22.4 ± 2.05 (range, 18-27) years for Groups 1 and 2, respectively (p=0.259). In Group 1, measurements between the two analyses were significantly different for the values of anterior chamber depth (ACD), anterior chamber angle (ACA), and anterior chamber volume (ACV) (p<0.05), whereas no statistical difference was found for the central corneal thickness (CCT) and keratometry (K1, K2) measurements. In Group 2, none of these parameters were statistically different between the two analyses.

Conclusions:

Topically applied 1% cyclopentolate hydrochloride caused an increase in the ACD and ACV values, and a decrease in the ACA value. However, it had no significant effect on the CCT and keratometry measurements. It is important to consider these effects when using the Pentacam device on young adults with cycloplegia and when applying it for various reasons. .
RESUMO

Objetivo:

Pesquisar os efeitos do cloridrato de ciclopentolato a 1%, aplicado topicamente, em parâmetros do segmento anterior medidos com a câmera de Scheimpflug Pentacam em adultos jovens e saudáveis.

Métodos:

A análise do segmento anterior, de 25 olhos de 25 jovens adultos (Grupo 1), antes e após 45 minutos da aplicação de cloridrato ciclopentolato a 1%, foram realizados. Como grupo controle (sem cicloplegia, Grupo 2), 24 olhos de 24 pacientes saudáveis pareados por idade e sexo, foram avaliados duas vezes em intervalos de 45 minutos. Os resultados obtidos com os grupos foram comparados estatisticamente.

Resultados:

A média de idade dos grupos foram 23,04 ± 3,42 (18-29 anos) e 22,4 ± 2,05 (18-27) anos, respectivamente (p=0,259). No Grupo 1, as medidas entre os dois exames foram significativamente diferentes para os valores de profundidade da câmara anterior (ACD), ângulo da câmara anterior (ACA), e do volume da câmara anterior (ACV) (p<0,05 para todos), enquanto que não foram diferentes para a espessura corneana central (CCT) e ceratometria valores (K1, K2). No Grupo 2, nenhum destes parâmetros foi diferente entre os dois exames.

Conclusões:

Aplicação tópica de cloridrato de ciclopentolato a 1% causou um aumento nos valores de ACD e ACV e uma diminuição nos valores da ACA. No entanto, ele não teve nenhum efeito significativo sobre as medidas de CCT e ceratometria. É importante considerar esses efeitos sobre as medidas tomadas com Pentacam em adultos jovens com cicloplegia quando aplicá-las em diferentes situações. .
