To the Editor.—Thank you for giving us the opportunity to reply to Dr. Hockman's letter concerning our article which appeared in The Journal.
Our ophthalmoscopic findings in the patients with GSD, type 1 were not consistent with the classical description of lipemic retinalis. It is possible that the changes described in a patient with type V hyperlipoproteinemia1 are "intermediate between typical lipemic retinalis and our findings."
We agree with Dr. Hochman that additional data are necessary before an adequate classification is possible.
