A case of orbital hypertelorism with recovery of binocular vision after surgical treatment.

Orbital hypertelorism is defined as an abnormally wide bony interorbital distance. The aims of surgery are both correction of ocular dystopia and cosmetic reconstruction of the nasal crest. Marked improvement of visual function, especially binocular vision, by surgery is not expected. Here we report that surgical treatment unexpectedly resulted in a significant visual improvement for a 13-year-old boy with orbital hypertelorism who also had bilateral cleft lip and palate.
