[Histological particularities of sclerocorneal limbus--implications in ocular pathology]

The study tried to compare the sclerocorneal limbus in human eyes and animal eyes, using the same histological technique (preserving in paraphine and stained with hematoxylin-eosine, trichromic Goldner-Szekelly and orceine method). The sclerocorneal limbus represents the passage zone between cornea and sclera, and its importance for medical practice, consists on the implications of this area in the ocular physiology. We have demonstrated in this study that the two structures are not interrupted briefly; the corneal epithelium at the limbus send in the deeper structure a ramification which represents a modality of stronger anchorage of subjacent conjunctiva. At that level it is detectable a gradual translation between corneal conjunctival tissue and scleral conjunctival tissue. The vascular and neural structures are important in this area with an important role in ocular surgery, their presence of this level permeating the cicatrisation.
