Biopsy of human scleral-chorioretinal tissue.

The usefulness of a technique for scleral-chorioretinal biopsies was evaluated on a human eye destined for enucleation due to a malignant melanoma of the choroid. The operative procedure was without complication. The biopsy specimen was removed and carefully evaluated both by light and electron microscopy. The underlying choroid and retinal tissues were successfully preserved by this technique.
