Development of schematic representations for globe removal and formation of the supporting-motor stump for use in ophthalmological and radiological practice

Abstract

BACKGROUND: Today, the issue of globe endoprosthetics is an extremely important problem due to several reasons: the presence of various methods for globe removal, the variety of implants and surgical installation techniques, non-standard cavities before prosthetics, the lack of a unified algorithm for examining the patients at the pre- and postoperative stages, as well as difficulties in the rehabilitation of patients with anophthalmos and high aesthetics requirements. AIM: Development of schematic images of performing various surgical techniques for globe removal and forming a supporting-motor stump for a cosmetic prosthesis. MATERIALS AND METHODS: During 2020–2023, in different institutions, 43 patients (100%) were examined for globe endoprosthetics, from 18 to 65 years old, 23 men, 20 women. The authors analyzed CT data obtained at the radiological department No. 2 of Sechenov University and at the 1586 Military Clinical Hospital of the Russian Ministry of Defense. RESULTS: All patients (n = 43; 100%) underwent a globe removal in various modifications depending on the initial condition, in 39 cases (78%) — reconstructive surgery for the endoprosthesis installation in order to form a volumetric supporting-motor stump, and further external cosmetic prosthetics. In 10 patients (22%), the endoprosthesis was installed after enucleation of the globe, in 33 (78%) — after evisceration in various modifications. CONCLUSIONS: This paper presents schematic images of various techniques for surgical globe removal, formation of a supporting-motor stump, types of endoprostheses, the options of external cosmetic prosthetics and the presence of complications, as well as a CT protocol for the description of obtained images.
