[Intraoperative ultrasound diagnosis in the removal of intraocular foreign bodies].

ABSTRACT

The paper provides a rationale and indications for diascleral removal of foreign bodies from the anterior chamber of the eyeball, by intraoperatively using ultrasound study. The clinical material presents 148 cases of diascleral removal of foreign (49 magnetic and 49 amagnetic) bodes impacted into the tunics of the anterior eye without evident opacities of optical media and without signs of endophthalmitis. The paper provides a pathogenetic rationale for the method that is lowly traumatic and highly effective (foreign bodies being removed in 99.9% of cases) due to the high precision of location of a scleral cut in the projection of foreign body bedding owing to intraoperative sound usage. A model clinical case of fragment removal is also shown in the paper. The specific features of criteria for using the method are described, by taking into account the anatomic characteristics of orbital eyeball location.
