The lecture provides a detailed description of the development of retinal vessels, vasculogenesis and angiogenesis. The cascade of protective mechanisms of the organism of the system of combating hyperoxia, the system of combating circulatory hypoxia and the key growth factors of the vascular endothelium during angiogenesis are shown. The pathogenesis of retinopathy of prematurity is described and the first phase of ROP development is analyzed in detail, the reasons for the delay in the maturation of vascular autoregulation are explained. The author proposed to distinguish the first preclinical phase in the ROP classification. In contrast to the modern concentration of attention of ophthalmologists on the active and cicatricial stages, the author proposes to pay special attention to the study of the preclinical stage of ROP, where its pathogenesis is formed.

Retinoblastoma is the most frequent ocular malignancy in the pediatric population and intra-arterial chemotherapy has emerged as the first-line treatment of this entity with cure rates ranging from 33–100%, depending on the severity of the disease. We present the case of an advanced retinoblastoma in a pediatric patient who underwent intra-arterial chemotherapy through a contralateral route due to unsuccessful catheterization of the ophthalmic artery. The patient was diagnosed with a class D retinoblastoma which underwent the catheterization of the ophthalmic artery through the contralateral internal carotid and through the anterior communicating artery. In this case, intra-arterial chemotherapy administration was successfully delivered without complications. Contralateral routes for intra-arterial chemotherapy are safe and allow adequate penetration of the chemotherapeutic drugs in cases where a well-developed anterior communicating artery is present.
