Mangement of infantile esotropia.
We evaluated the management of infantile esotropia-constant, alternating esotropia before 6 months of age-in 34 children. Planned one-state surgery for satisfactory mechanical alignment was highly predicatable (79 to 84%), and was obtained at any age. Stable bifoveal motor fusion was also obtained but was more frequent with alignment before 2 years of age. The use of postsurgical spectacle orthoptics (minus lenses or prisms, or both) increased the incidence of bifoveal fusion. Surgery alone resulted in bifoveal fusion in 6% of the cases, whereas an overall incidence of 33% bifoveal fusion resulted after the use of postsurgical spectacle orthoptics by some patients. Of those receiving postsurgical spectacle orthoptics, 53% obtained bifoveal fusion. This study demonstrated a correlation between the incidence of secondary A patterns (after surgery for V esotropia) and the amount of horizontal muscle surgery done in combination with bilateral inferior oblique muscle myectomies.
