Rare case of pathological biomineralization of eye tissue

Abstract

Авторами описан случай патологической биоминерализации задней камеры глаза. При гистологическом исследовании в оболочках пораженного глаза выявлено воспаление, отек, дисциркуляторные нарушения, признаки дистрофической кальцификации. При структурно-фазовом и химическом анализе материала кальцификата установлено, что биоминерал состоит из гидроксиапатита с относительно малыми размерами кристаллитов и дефектной кристаллической решеткой. В описанном случае образование патологического биоминерала в органе зрения было инициировано проникающим ранением. Травма глаза, вероятно, обусловила гемофтальм и хроническую воспалительную реакцию в оболочках, эти процессы со временем привели к субатрофии органа, развитию дистрофических и некробиотических изменений в тканях. Патологическая биоминерализация в пораженном органе зрения развивалась по типу дистрофической кальцификации. The authors have described the case of pathological biomineralization of ocular posterior chamber. Histological examination of affected eye shells revealed inflammation, oedema, dyscirculatory violations, and signs of dystrophic calcification. Structural-phase and chemical analyses of calcification have revealed that the biomineral consists of hydroxyapatite with relatively small crystallite size and defective crystal lattice. In the described case the formation of pathological biomineral in the vision organ was initiated by penetrating wound. Eye injury might have caused a hemophthalmus and chronic inflammatory reaction in the shells, these processes eventually led to the organ subatrophy and to the development of dystrophic and necrobiotic changes in the tissues. Pathological biomineralization in the affected organ developed as a type of dystrophic calcification.
