[Utility of ultrasonography in toxoplasmic uveitis].
OBJECTIVE
To analyze the main indications and the most common ultrasonographic features observed in uveitis due to toxoplasmosis.


METHODS
We carried out a retrospective, observational and descriptive study performed in 97 exams corresponding to 89 patients with uveitis during 7 consecutive years (1994-2000) using B-ultrasonography evaluation.


RESULTS
The main ultrasonographic indication in toxoplasmosis was vitreous opacity. We observed that the most frequent findings were: a) intravitreous punctiform echoes, b) thickening of posterior hyaloid, c) partial or total posterior vitreous detachment and d) focal retinochoroidal thickening. This last finding should be highlighted due to its significant correlation (p<0.01) with toxoplasmosis.


CONCLUSIONS
Our results suggest that ultrasonography plays an important role in the diagnosis and clinical follow-up of toxoplasmic uveitis.
