[Value of echography for diagnosis and follow-up of perforating eye injuries].

The introduction of vitreous surgery with its multiple capabilities of intraocular manipulations makes it possible to operate on cases which had been considered as hopeless up to now. With these techniques the importance of ultrasonic examination increased especially in cases with severe perforating injuries and their follow-up, to detect the onset of intravitreal fibrosis and early traction detachment, when no fundus view is possible. An other indication for ultrasonic examination is the exact localization of foreign bodies. Out of 484 perforating injuries which were examined and treated in our clinic during the last 10 years, ultrasonographic diagnosis was helpful in 18% and had further therapeutic consequences: In 24% a detachment operation or vitreous surgery was necessary, in 30% ultrasonography showed severe damage and surgery was considered to be ineffective. 42% were follow-up examinations of the posterior segment.
