Study reviews axial length growth rate in children




Children’s eyes with a shorter axial length than the fellow eye showed post-op rate of axial growth that exceeded the growth rate of eyes with a longer interocular axial length.

Rupal H. Trivedi M.D., MSCR, Storm Eye Institute, Medical University of South Carolina, Charleston, and her colleague performed a retrospective chart review of 47 eyes and presented their results in a recent issue of the Journal of American Association for Pediatric Ophthalmology and Strabismus.

For the review, Dr. Trivedi excluded eyes with traumatic and secondary cataract, lens subluxation or post-op glaucoma. In bilateral cataract cases, only right eye data were included. In addition, eyes were included only if axial length data for both eyes were available before surgery and at follow-up equal to or greater than the age at surgery. Three groups were formed based on the pre-op interocular axial length difference: group 1, < ?0.2; group 2, ? ?0.2 and ? 0.2; and group 3, > 0.2. The change in interocular axial length difference (post-op interocular axial length difference minus pre-op interocular axial length difference) was significant between the three groups (0.3, 0.2, ?0.4 mm, respectively; P= 0.02). The average rate of axial length growth was significantly different between three groups (3.7, 2.4, 2.5 mm, respectively; P= 0.03).

These growth rates resulted in a post-op trend of intraocular axial length difference toward zero, Dr. Trivedi said.
