RESUMO

OBJETIVO:

Comparar a acurácia do teste de fixação preferencial quando o paciente olha e toca o objeto alvo ao invés de apenas olhá-lo, como convencionalmente descrito.

MÉTODOS:

Estudo piloto transversal e prospectivo, incluindo 40 pacientes estrábicos, com desvios maiores que 10 dioptrias prismáticas entre 7 e 30 anos.

RESULTADOS:

O teste modificado mostrou sensibilidade de 93% (IC 95%=68,53 -98,73%) e especificidade de 77% (IC 95%=57,95 - 88,97%). O teste convencional apresentou sensibilidade de 93% (IC 95%=68,53 - 98,73%) e especificidade 46% (IC 95%= 28,76 - 64,54%).

CONCLUSÕES:

Estes resultados sugerem que a modificação no teste de fixação preferencial, solicitando que o paciente toque o objeto alvo, possa reduzir os resultados falsos positivos do teste.
ABSTRACT

PURPOSE:

To compare the accuracy of the fixation preference test performed with the patient touching and looking at the fixation target, to the conventional method test done with the patient only looking at it.

METHODS:

A pilot transversal and prospective study was done with 40 strabismic patients with deviations greater than 10 prism diopters, from 7 to 30 years old.

RESULTS:

The modified test had a sensitivity of 93% (IC 95%=68.53 - 98.73%) and specificity of 77% (IC 95%=57.95 - 88.97%); while the conventional test had a sensitivity of 93% (IC 95%=68.53 - 98.73%) and a specificity of 46% (IC 95%=28.76 - 64.54%).

CONCLUSIONS:

Our results suggest that the modification of the fixation preference test by asking the patient to touch the fixation target might reduce the number of false positive results of the test.
