ОСТЕОМА ХОРИОИДЕИ: КЛИНИКО-ДИАГНОСТИЧЕСКИЕ ОСОБЕННОСТИ

Abstract

Objective: To present own experience of choroidal osteoma (CO) management. Methods: The study included 4 patients (4 eyes), who were monitored from 2018 to 2019. The age of the patients ranged from 17 to 45 years (average age – 29 years). According to the indications, an angiogenesis inhibitor was injected intravitreally to one patient. One patient underwent diode laser thermotherapy. Follow-up without treatment was recommended for two patients. Results: In all cases, CO was presented by a yellowish paramacular or juxtapillary mass, which flatly elevated into the vitreous body. In one case, the presence of choroidal neovascularization (CNV) in the tumor area was noted, in another – retinal detachment on the basis of the CO. In the ultrasonic B-scan, the CO looked like a high acoustic signal mining formation, giving a shadow into the retrobulbar space. According to CT scans in all patients, the osteoma looked like a plaque of bone density in the choroid. As a result of the treatment in both patients, the height of the foci decreased from 0.77 and 1.8 mm to 0.5 and 1 mm, respectively. In addition, there was a significant reduction in the number of newly formed vessels. In patients under dynamic, no changes were detected. Conclusion: CO has a polymorphic clinical picture, the manifestations of which depend on the location of the tumor and the complications caused by it. Auxiliary diagnostic methods are B-scan, optical coherent tomography and CT scans of the orbits. In most cases, CO requires only dynamic observation. In such complications as CNV and the detachment of neuroepithelium, the treatment is aimed at reducing the number of newly formed vessels, reducing exudation and serous detachment of the retina to restore the maximum possible visual functions of the eye.
