Random dot stereoacuity following surgical correction of infantile XXXX .

@entity1 @entity5971
Surgical correction of infantile @entity5971 prior to age 2 is associated with a higher prevalence of fusion and stereopsis than surgical correction after 2 years of age. The advantages and disadvantages of surgical intervention at the early or late end of this window have been debated in the literature. In the present study, random dot (RD) stereoacuity outcomes were evaluated in order to determine whether a binocular sensory benefit is associated with early or late surgery. @entity1 were 73 healthy @entity1 enrolled in a prospective study of visual development in infantile @entity5971 . All @entity1 had initial surgical correction at 5 to 16 months of age. RD stereoacuity was evaluated at approximately 5 years of age (59.7 +/- 14.9 months). Overall, 41.1% of @entity1 demonstrated RD stereopsis. The percentage of @entity1 demonstrating RD stereopsis was not significantly different among groups that were surgically corrected at 5 to 8 months (43.8%), 9 to 12 months (47.4%), and 13 to 16 months (31.8%). However, among those @entity1 who achieved RD stereopsis, the prevalence of foveal (< 60 sec) or macular (61 to 200 sec) stereoacuity was significantly higher among those who had surgery at 5 to 8 months (42.9%; Z = 2.06, p < 0.02) or 9 to 12 months (55.6%; Z = 2.38, p < 0.009) than among those who had surgery at 13 to 16 months (0.0%). Although surgical correction of infantile @entity5971 during the first year of life is not associated with a higher prevalence of RD stereopsis, it is associated with better RD stereoacuity among those @entity1 who achieve stereopsis following surgery.
