Measurements of ocular coat dimensions by means of combined A- and B-scan ultrasonography.

In various states of refraction axial eye length and thickness of the posterior ocular coats were measured echographically. As proved in previously performed experimental studies, retina, choroid and sclera were resolved in a considerable percentage of cases by combining the A- and B-mode techniques of modern ultrasonic equipment. The supposed close negative correlation between length of the globe and ocular coat dimensions was confirmed by statistical analysis of our data. This result should provide additional help, when interpreting the reflections of the ocular wall under normal and pathological conditions.
