Resumo
Purpose: To evaluate the influence of 2% ibopamine eye
drops on the results of computerized visual field exams. Me-
thods: Normal volunteers from CEROF-UFG were selected,
with no variance in the ophthalmologic examination that could
affect the visual field test. The volunteers underwent compu-
terized visual field test before and after dilation with 2% ibo-
pamine eye drop or cyclopentolate, with a minimum interval of
three days between them and in a random order. Global indices
and number of altered points were compared between the
groups. Results: Thirty eyes of 30 normal individuals were
selected. There was no statistically significant difference on
Mean Deviation (MD) before and after dilation with ibopa-
mine (MD: -1.05 ± 0.26 dB vs. -1.47 ± 0.20 dB, P=0.08). Ho-
wever, after cycloplegia (MD: -3.19 ± 0.29 dB), there was a
significant difference on MD (P<0.001 for both ibopamine and
pre-dilation). No significant difference was detected in the
Pattern Standard Deviation when comparing ibopamine with
pre-dilation and cycloplegia values, but it was statistically
significant comparing pre-dilation to cycloplegia (P=0.04).
The number of altered points in the Pattern Deviation graphic
were not significant comparing all pairs. There was a sta-
tistically significant difference in the number of altered points
in the total deviation graphic before dilation and after cyclo-
plegia (n: 8.86 ± 1.51 vs. 25.72 ± 2.96 points, P<0.001), and
comparing cycloplegia with ibopamine (ibopamine: 9.75 ± 1.85
points, P<0.001). Conclusion: Ibopamine 2% eye drops seem
to not modify the results of visual field tests in normal
individuals.
