Ultrasonographic characteristics of active ocular toxoplasmosis
Morais,Fábio Barreto; Arantes,Tiago Eugênio Faria e; Muccioli,Cristina; Allemann,NormaABSTRACT 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, po...
Anterior segment optical coherence tomography findings in type I Boston keratop...
Silva,Luzia Diegues; Santos,Albert; Sousa,Luciene Barbosa de; Allemann,Norma; Oliveira,Lauro Augusto deABSTRACT Purpose: To report the results of high-resolution anterior segment optical coherence tomography of patients implanted with a type 1 Boston keratoprosthesis (KPro). Methods: The retrospective study cohort included 11 eyes of 11 patients (average age, 58.4 years; range, 34-83 years). All subjects underwent anterior segment optical coherence tomography at a single posteoperative time point. The main outco...
Comparisons of choroidal nevus measurements obtained using 10- and 20-MHz ultra...
Martins,Maíra de França; Kiefer,Kelcia; Kanecadan,Liliane Almeida Andrade; Garcia,Patricia Novita; Belfort,Rubens N.; Allemann,NormaABSTRACT Purpose: To compare measurements of lesions clinically diagnosed as choroidal nevi using spectral domain optical coherence tomography (SD-OCT) and 10- and 20-MHz ultrasound (US). Methods: This prospective study, which was conducted between May 2011 and December 2011, evaluated eyes diagnosed with choroidal nevus via photographic documentation using 10- or 20-MHz A- and B-mode US (experienced examiner u...
Ultrasound parameters of normal lacrimal sac and chronic dacryocystitis
Machado,Marco Antonio de Campos; Silva,João Amaro Ferrari; Garcia,Eduardo Alonso; Allemann,NormaABSTRACT Purpose: To compared the ultrasound findings of the lacrimal sac between subjects with normal lacrimal systems those with chronic dacryocystitis. Methods: A retrospective study of 10 subjects with a normal lacrimal system (Group 1) and 10 with chronic dacryocystitis (Group 2) diagnosed according to B-mode ultrasound with a 10-MHz transducer and the direct-contact technique (AVISO, Quantel Medical) for ...
Aqueous misdirection syndrome in persistent fetal vasculature (PFV)
Kato,Renata Tiemi; Borba,Paula Delegrego; Moura,Christiane Rolim de; Allemann,Norma; Moraes,Nilva Simeren Bueno deABSTRACT We report a case of a 5-year-old girl with persistent fetal vasculature who presented with unilateral acute angle closure caused by aqueous misdirection syndrome that was apparently associated with regression of cycloplegia. Initial treatment with topical steroids, anti-glaucomatous drops, and atropine showed insufficient control of the intraocular pressure (IOP). Surgical treatment with lensectomy and...
Using thermography for an obstruction of the lower lacrimal system
Machado,Marco Antonio de Campos; Silva,João Amaro Ferrari; Brioschi,Marcos Leal; Allemann,NormaABSTRACT Obstructions in the lacrimal pathways quite often require accurate and reliable image scanning for confirmation and documentation. Infrared thermal imaging, known as thermography, is a resource that complements diagnosis; it does not require touching the patient or applying contrast materials and has been used in various medical procedures for decades. However, there have been few studies in the litera...
Ophthalmic Doppler in persistent hyperplastic primary vitreous atypical present...
Morales,Maira Saad de Avila; Tartarella,Márcia Beatriz; Gouveia,Enéias Bezerra; Mandello,Maria Helena; Allemann,NormaABSTRACTThe purpose is to document a case of persistent hiperplastic primary vitreous (PHPV) with atypical Bergmeister's papilla and patent hialoid artery that had its conclusive diagnosis done by doppler ultrasound. We report a case of child, who had unilateral leucokoria. This child's fundoscopic examination showed a white mass on the optic nerve that extended over to adjacent retina. Performed ultrasound tha...
Direct cyclopexy surgery for post-traumatic cyclodialysis with persistent hypot...
Murta,Fabiola; Mitne,Somaia; Allemann,Norma; Paranhos Junior,AugustoCyclodialysis is a relatively rare condition usually caused by ocular injury; however, it can also be caused iatrogenically during intraocular surgery. Hypotony maculopathy is the most important complication and the primary reason for visual loss. Clinical diagnosis using gonioscopy may be difficult, and ultrasound biomicroscopy (UBM) can be an alternative. There are different kinds of treatments, and the optim...
Congenital dacryocystocele: diagnosis using ante and post-natal ultrasonography
Machado,Marco Antonio de Campos; Abreu Junior,Luiz de; Silva,João Amaro Ferrari; Allemann,NormaCongenital dacryocystocele is an unusual type of nasolacrimal obstruction. Treatment with antibiotics or surgical removal is practiced to reduce the risks of infection (acute dacryocystitis) and potentially lethal septicemia. Here, we report a case of congenital dacryocystocele, antenatal ultrasonographic diagnosis (intrauterine), and postnatal reassessment.
Ultrasound biomicroscopy after palliative surgical procedures for bullous kerat...
Paris,Fabiana dos Santos; Gonçalves,Eliana Domingues; Morales,Maira Saad Ávila; Kanecadan,Liliane Andrade Almeida; Campos,Mauro Silveira de QueirozPurpose: To describe quantitative and qualitative features of eyes with advanced bullous keratopathy assessed using ultrasound biomicroscopy, before and after anterior stromal puncture (ASP) or amniotic membrane transplantation (AMT) procedures to relieve chronic pain. Methods: The present descriptive comparative study included 40 eyes of 40 patients with chronic intermittent pain due to bullous keratopathy who...
