[The interrelations between the pigment cells of the uveal tract and the cell population of the retina in ontogeny]. / Aspecte ale interrelatiilor dintre celulele pigmentare din tractul uveal si populatia celulara din retina în ontogeneza.

The authors suggest themselves to follow in dynamic the cellular retinal population in different ontogenetic phases and also the progress of pigmentagenesis in the uveal tract and in the enteral stratum of the retina. For this purpose there have been used eyes from embryos and fetuses from the interrupted pregnancies. The obtained material was processed in the classical hystological technique and for the objectiveness of the phenomena there have been used methods of biometry. The authors, reached the conclusion that the pigmenting of the uveal stratum is made simultaneously with the loading with pigment of the enteral stratum of the retina, under the influence of different factors, especially the humoral ones and the evolution of the cellular retinal population varies, depending on ontogenetic phases and ages till birth.
