[Block-excision of intraocular processes. II. Epithelial ingrowth into the anterior segment of the eye (author's transl)].

Extensive posttraumatic epithelial ingrowth was completely removed by block-excision of 10 to 11 nm diameter from 3 eyes. The cyst is excised together with adjacent cornea, sclera, iris and ciliary body as a single "block". Thus direct manipulation of the delicate wall of the intact cyst is avoided, the invading epithelium is totally eradicated and a recurrence impossible. The defect of the globe extending up to 6 mm beyond the limbus is covered by a tectonic corneal graft. This procedure was derived from a clinicopathologic study of 35 epithelial ingrowths among 1300 enucleations between 1966-1974. Attempts of excision confined to cornea and iris always have been incomplete. 25 enucleated globes with epithelial ingrowth revealed an attached retina in 16 eyes indicating probably useful visual acuity in case of early complete "block-excision".
