The authors describe a case report of idiopathic asymptomatic giant retinal cyst with underlying hyperpigmentation. Low- and high-frequency ultrasound (ultrasound biomicroscopy) revealed an anechoic giant cyst with two hyper-reflective traction bands between the ciliary body and the anterior base of the retinal cyst. There was no retinal detachment.

A nterior segment optical coherence tomography (OCT) is a noninvasive, painless, noncontact technique that provides accurate and reproducible images. This technique correlates well with ultrasound biomicroscopy, allows observation of iridocorneal angle abnormalities in the presence of opaque media, and is easier to perform than ultrasound biomicroscopy. A cyclodialysis cleft results from separa...

The present work applies Gabor filters bank for texture analysis of skin lesions images, obtained by ultrasound biomicroscopy. The regions affected by the lesions were differentiated from surrounding tissue in all the analyzed cases; however the accuracy of the traced borders showed some limitations in part of the images. Future steps are being contemplated, attempting to enhance the technique ...

PURPOSE To evaluate the visual acuity outcomes and to investigate the intraocular lens (IOL) and endocapsular ring positions with ultrasound biomicroscopy in 17 eyes of 10 patients with congenital lens subluxation who underwent the same surgical technique, by the same surgeon. METHODS The study was performed in the ''Hospital de Olhos de Pernambuco'' and ''Fundação Altino Ventura''. The surgi...

IMPORTANCE Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare paraneoplastic syndrome with characteristic findings, including exudative retinal detachment, rapid cataract formation, and uveal melanocytic tumors. We report a case notable for bilateral iris and ciliary body cysts--a rare presentation of the disease. OBSERVATIONS A woman in her 50s presented with bilateral decre...

PURPOSE To describe the morphologic alterations in ultrasound biomicroscopy (UBM) present in peripheral vitreoretinal toxocariasis. METHODS An observational prospective study of case series. Fifteen eyes of 15 patients with clinical and laboratory diagnosis of peripheral vitreoretinal toxocariasis were enrolled. The patients were submitted to UBM examination of the region corresponding to the...

UBM is a high-frequency ultrasound technology that provides exceptionally detailed two-dimensional gray-scale images of the various anterior segment structures and evaluates them both quantitatively and qualitatively. It allows noninvasive in vivo imaging of structural details of the anterior ocular segment at near microscopic resolution and thus, there are many other applications of this new i...

Ultrasound biomicroscopy (UBM) is being used increasingly in cataract and refractive surgery to evaluate phacomorphic lenses, dislocated intraocular lenses, misplaced haptics, sulcus-to-sulcus measurements for implantable Collamer lenses (ICLs), ciliary body cysts before ICL implantation, retained lens fragments, and anterior effusions. In a previous report, biometry apparatus grew pathogenic f...

Anterior segment imaging allows for an objective method of visualizing the anterior segment angle. Two of the most commonly used devices for anterior segment imaging include the anterior segment optical coherence tomography (AS-OCT) and the ultrasound biomicroscopy (UBM). AS-OCT technology has several types, including time-domain, swept-source, and spectral-domain-based configurations. We perfo...

PURPOSE To report the occurrence of an astrocytoma of the ciliary body. METHODS The patient was evaluated by ophthalmoscopic examination (including color ultrasonography and ultrasound biomicroscopy) as well as operating therapy. Histopathology and immunocytochemical analysis were performed. RESULTS A 29-year-old woman was found to have a left ciliary body tumor. Color ultrasonography revea...
