Resumo: O objetivo deste estudo foi determinar os valores médios da freqüência crítica de fusão (FCF), a flutuação a curto prazo e a variabilidade inter e intra-individual, analisar a influência da idade e sexo e investigar a ocorrência de efeito aprendizado em indivíduos normais submetidos à perimetria ¿flicker¿. A investigação foi dividida em dois estudos. No estudo 1, 95 indivíduos normais foram submetidos à perimetria ¿flicker¿ com o perímetro Octopus 301 (programa G1, estratégia dinâmica) em um olho. Determinaram-se os seguintes valores da FCF: média global, média dos pontos centrais, média dos pontos periféricos, média foveal e média dos quadrantes. Os valores médios foram comparados entre ambos os sexos e a influência da idade foi avaliada utilizando análise de regressão linear. No estudo 2, 20 indivíduos normais foram submetidos à perimetria ¿flicker¿ cinco vezes. Os três primeiros exames foram realizados em dias diferentes, separados por intervalos que variaram de um a 30 dias, enquanto os três últimos exames foram realizados no mesmo dia com intervalos de pelo menos 15 minutos. Os valores obtidos nos três primeiros exames foram utilizados para investigar o efeito aprendizado. A flutuação a curto prazo foi definida como a média das diferenças obtidas entre o valor da FCF mais alto e o mais baixo para cada ponto testado considerando-se os três últimos exames. Também determinou-se a variabilidade média dos valores de FCF inter e intra-individual. No estudo 1, os valores médios de FCF global, foveal, central e periférica foram, respectivamente, 38,2±4,3Hz, 36,4±3,5Hz, 38,7±3,7Hz e 37,9±5,0Hz. O valor médio de FCF periférica foi significativamente menor do que o valor médio de FCF central (p=0,007). A análise de regressão linear demonstrou que os valores médios FCF global, foveal, central, periférico e por quadrante diminuíram significativamente com a idade, porém com baixo coeficiente de determinação (R2 variando entre 0,074 e 0,163). Não houve diferença estatisticamente significante nos valores médios de FCF entre os indivíduos do sexo masculino e feminino (p>0,05) com exceção da área central e do quadrante nasal inferior, onde os valores foram significativamente menores no sexo feminino (p=0,029 e p=0,008 respectivamente). No estudo 2, a comparação entre os três primeiros exames não mostrou diferença estatisticamente significante em relação à duração do teste, porcentagem de respostas falso-positivas e falso-negativas (p>0,05). Os valores médios de FCF global (p=0,010), central (p=0,13) e periférico (p=0,033) foram significativamente menores no 1º exame em relação ao 2º exame . A média global da flutuação a curto prazo foi 5,06±1,13Hz, a li variabilidade média inter-individual foi 11,2±2,3% e a variabilidade média intra-individual foi 6,4±1,5%. Este estudo sugere que os valores da FCF diminuem com a idade e não são influenciados significativamente pelo sexo. Também sugere que a perimetria ¿flicker¿ está associada a efeito aprendizado e que flutuação a curto prazo e variabilidade inter e intra-individual moderadas são esperadas em indivíduos normais submetidos a este teste
Abstract: The aim of this study was to determine the mean critical fusion frequency (CFF), the short term fluctuation and inter and intraindividual variability, to analyze the influence of age and gender, and to investigate the occurrence of a learning effect in healthy subjects undergoing flicker perimetry. The investigation was divided in two study. In study 1, 95 normal subjects underwent flicker perimetry (Octopus 301, G1 program, dynamic strategy) in one eye. Mean global, central, peripheral, and foveal CFF values were determined, as well as mean CFFs per quadrant. Mean CFF values were compared between the two genders, and the influence of age was evaluated using linear regression analysis. In study 2, 20 normal subjects underwent flicker perimetry 5 times. The first 3 sessions were separated by an interval of 1 to 30 days, whereas the last 3 sessions were performed within the same day, with 15-minute intervals. The analysis of the first 3 sessions was used to investigate the presence of a learning effect. The mean of the differences between the highest and the lowest CFF value for each tested point during the last 3 tests were used to calculate the short term fluctuation (SF). Mean interindividual and intraindividual variabilities were determined. In study 1, mean global, foveal, central, and peripheral CFFs were 38.2±4.3Hz, 36.4±3.5Hz, 38.7±3.7Hz, and 37.9±5.0Hz, respectively. The mean peripheral CFF was significantly lower than the mean central CFF (p=0.007). Linear regression analysis demonstrated that mean global, foveal, central, and CFF per quadrant significantly decreased with age, however with a low correlation coefficient (R2 ranging between 0.074 and 0.163). There were no statistically significant differences in mean CFF values between males and females (p> 0.05), with the exception of the central area and the inferonasal quadrant, where the values were significantly lower in females (p=0.029 and p=0.008, respectively). In study 2, there were no statistically significant differences among the first three sessions regarding test duration, rates of false positive and false negative responses (p>0.05). The mean global (p=0.010), central (p=0.013), and peripheral (p=0.033) CFFs were significantly lower in first session compared to the second session. The mean global SF was 5.06+1.13Hz, the mean interindividual variability was 11.2±2.8%, and the mean intraindividual variability was 6.4+1.5%. This study suggests that CFFs decrease with age, and that CFFs are not significantly influenced by gender. It also suggests that flicker perimetry is associated with a learning effect, and that moderately high short term fluctuation and inter and intraindividual variability were expected in normal subjects undergoing such test
