SANTOS HERCOS, BV; MUINOS, SJ  and  CASAROLI-MARANO, RP. Utility of ultrasonography in toxoplasmic uveitis. Arch Soc Esp Oftalmol [online]. 2004, vol.79, n.2, pp.59-65. ISSN 0365-6691.

Purpose: To analyze the main indications and the most common ultrasonographic features observed in uveitis due to toxoplasmosis. Material and 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.
