RESUMO
Os autores relatam a rara associação de efusão uveal e tuberculose ocular presumida em paciente do sexo masculino que apresentou melhora clínica com o uso sistêmico de prednisona 40 mg/d e rifampicina 600 mg/d. Descrevem, ainda, aspectos relevantes da efusão uveal, como etiopatogenia, evolução da doença, diagnóstico diferencial e tratamento, por meio de revisão da literatura.
The authors report a rare association of uveal effusion with presumed ocular tuberculosis in a male patient who presented clinical improvement with the systemic use of prednisone 40 mg/d and rifampicin 600 mg/d. In addition, relevant aspects of the uveal effusion such as the pathogenesis, evolution of the disease, differential diagnosis and treatment are described through a revision of the literature.

PURPOSE: To determine the pathogenesis of transient myopia after blunt eye trauma. METHODS: In one patient, the refraction of both eyes (the left eye was injured, but the right eye was not) was measured with an autorefractometer. The cycloplegic refraction was measured at the early stage of trauma and again 3 months after the blunt eye injury. The angle and depth of the anterior chamber, the ciliary body, and the choroids were examined by ultrasound biomicroscopy (UBM) over 3 months. The depth of the anterior chamber, the thickness of the lens, and the axial length were measured by A-scan ultrasonography in both eyes. During the 3 months after the injury, we made comparisons between the menifest and the cycloplegic refractions, the depths of anterior chambers, the thickness of the lenses, the axial lengths, and the UBM-determined appearances of the angles and depths of the anterior chambers, the ciliary bodies, and the choroids in both eyes. RESULTS: We suspect that the depth reduction in the anterior chamber, the increase in anterior to posterior lens diameter, and the edema in the ciliary body are all related to the change in the refractive power following the blunt trauma. CONCLUSIONS: Ultrasound biomicroscopy (UBM) and ultrasonography of the anterior segment in the eye may be helpful to diagnose and confirm changes in the refractive power that occur after trauma.

A total of 424 leprosy patients were screened for uveal involvement. Uveal changes were found in 11.2% of these patients. Uveal involvement was more common in patients with greater duration of the disease and in patients on irregular Dapsone therapy. Of the patients with uveal involvement 82% were lepromatous, 16% were borderline and 2% were of tuberculoid leprosy. Uveal changes in form of active iridocyclitis (21.3%), healed iridocyclitis (58.5%), iris atrophy (10.6%), iris pearls (7.4%), small irregular pupil (46.7%), pupil refractory to dilatation (56.3%) were seen. Posterior segment involvement was rare. Lepromatous and borderline leprosy patients with no clinical evidence of uveal involvement had decreased power of accommodation as compared to normal subjects.
