Study of the safety of long-term drainage of the suprachoroidal space with a polyurethane drainage tube (experimental study)

Abstract

The article describes the results of an experimental study of the safety of long-term drainage of the suprachoroidal space (SCS) with a polyurethane drainage tube. The work was performed on 10 rabbits (20 eyes) of the Chinchilla breed, in which a polyurethane drainage tube was implanted in the SCS. The safety of the proposed method was assessed using histopathological examination, eye biomicroscopy, ophthalmoscopy, fluorescein angiography. The study results show the safety of the polyurethane tube presence in the suprachoroidal space for up to 30 days. At the same time, the presence of the polyurethane drainage tube in the SCS for more than 30 days leads to irreversible pathological changes of inner eye tunics.
