Abstract

Purpose: to evaluate the functional changes in children with amblyopia

Methods: we analyzed 10 consecutive pediatric patients (10 eyes) with monocular amblyopia. All patients were submitted to a complete ophthalmic examination and microperimetry. Microperimetry with analysis of retinal sensitivities and fixation patterns were performed using a MP-1 (NIDEK Technologies) with a red cross of 2° as the fixation target, white background illumination of 4 asb, Goldman III stimuli with a projection time of 200 ms, and a customized grid of 68 stimuli around 10° centered on the fovea. Fixation was assessed according to Fuji et all and with evaluation of behavior countour ellipse area (BCEA).

Results: we analyzed 4 males and 6 females, age between 4 and 12 years. In 6 eyes we found a relatively unstable and central fixation, mean BCEA (68.2%) was 3.51 deg2 and mean retinal sensitivity was 15.4 dB. In these eyes, mean BCVA was 20/50. These children completed the full examination in about 07 minutes and 35 seconds (average time). In 4 eyes we found a stable and central fixation, mean BCEA (68.2%) was 0.94 deg2 and mean retinal sensitivity was 17.5 dB. In these eyes, mean BCVA was 20/32. These children completed the full examination in about 03 minutes and 18 seconds (average time).

Conclusions: our data suggest that fixation not change significantly in children with amblyopia and macular sensitivity is reduced. However, is also important to remember that evaluation of fixation in children may be also sensibly altered because of their poor cooperation, especially in infants.
