Blocked tear ducts may be linked to lazy eye

A new study finds children younger than age 2 who have blocked tear ducts are at greater risk for lazy eye or amblyopia.

It is a condition that could result in permanent vision loss if not treated early enough.

In the study, after examining 375 children with blocked tear ducts, the investigators found that 22 percent of them had risk factors for amblyopia. That is eight times higher than the general population.

Authors of the study in the Journal of AAPOS point out that the findings support the need for early comprehensive eye examinations.
