title: [A morphological study of tissues in the posterior segment of the eye after modified experimental revascularization of the choroid].
abstract: Morphologic examination of ocular tissues at the site of revascularization with two flaps was carried out to detect the changes in the architectonics of these flaps' vessels, vascular coating at the site of intervention, and assess the formation of relation with the vascular system of the external tissues of the eye. Experiments were carried out on the eyes of 8 cats. All the animals were subjected to local revascularization of the vascular coating with two flaps. Enucleation was carried out 1 to 6 months after the operation. The eyes were fixed in 10% neutral formalin solution, paraffin slices and blocks were prepared, stained with hematoxylin and eosin, with pyrofucin after Van Gieson, and with toluidine blue after Lison. Histologic study of ocular tissue slices 2-3 weeks after surgery showed that the flaps introduced into the supra-arachnoidal space tightly fitted each other forming a subconjunctival-episcleral transplant in which a moderate number of newly formed vessels was detected. Three to six months after surgery vascularization of the transplant proper and around it grew more and more intensive, the number of new vessels increased with their walls looking more compact; basal membrane appeared well shaped. The walls of new vessels did not differ by structure from normal vascular walls in the vascular coating.
