Ultrasonographic characteristics of active ocular toxoplasmosis
ABSTRACT Purpose: To evaluate ophthalmic ultrasonographic findings associated with active ocular toxoplasmosis. Methods: Forty-seven eyes with active ocular toxoplasmosis in 47 patients were subjected to ocular ultrasonography using the transpalpebral technique (10-MHz transducer) and fundus photography. Patient medical records were retrospectively reviewed. Results: Ocular ultrasonography revealed vitritis, posterior vitreous detachment, retinal wall thickening, and non-rhegmatogenous retinal detachment in 47 (100%), 36 [76.6%; partial in 12 (25.5%) and total in 23 (48.9%)], 12 (25.5%), and 5 eyes (10.6%). Thirty-five of the 36 eyes with posterior vitreous detachment (97.2%) exhibited posterior hyaloid thickening; moreover, adhesion to the exudative lesion and vitreoschisis were observed in 4 (11.1%) and 12 eyes (25.5%), respectively. Ultrasonography detected the location of the exudative focus in 12 eyes (25.5%). Conclusion: Ultrasonography is helpful for detecting important intraocular findings of acute ocular toxoplasmosis that can be hindered by medial opacity or posterior synechiae.
