PURPOSE To introduce a new convenient and accurate method to measure the angle kappa using ultrasound biomicroscopy (UBM) and corneal topography. METHODS Data from 42 eyes (13 males and 29 females) were analyzed in this study. The angle kappa was measured using Orbscan II and calculated with UBM and corneal topography. The angle kappa of the dominant eye was compared with measurements by Orbs...

OBJECTIVE To assess the agreement between findings obtained at dark-room gonioscopy and ultrasound biomicroscopy (UBM) in the diagnosis of iridotrabecular apposition in light and dark conditions. METHODS We enrolled patients with appositional angle closure at dark-room gonioscopy performed using a 1-mm slitlamp beam that did not cross the pupil. Ultrasound biomicroscopic images were acquired ...

PURPOSE To report a case with anterior and posterior nodules associated with systemic sarcoidosis. METHODS A patient with decreased vision underwent complete ophthalmologic examination, ultrasound biomicroscopy, fluorescein and indocyanine green (ICG) angiography. RESULTS The patient presented a nodule of the iris of the OS and of the optic nerves of both eyes. Chest computed tomography and...

Ultrasound biomicroscopy (UBM) remains a potent tool in the diagnosis and characterization of uveal lesions. In the setting of malignancy, it can confirm both placement of and response to brachytherapy. We present a case of iris melanoma with aggressive BAP-1 mutation, treated successfully with I-131 brachytherapy which was both characterized and followed with UBM and thereafter discuss the cur...

CASE REPORT A 61-year-old pseudophakic male with recurrent blurred vision episodes associated with uveitis, hyphema, glaucoma and vitreous hemorrhage. Iris transillumination defects and apposition of the optic and iris were found. The patient was diagnosed with Uveitis-Glaucoma-Hyphema (UGH) Syndrome. DISCUSSION Mechanical irritation of the iris is a consequence of intraocular lens malpositio...

Background. To evaluate the clinical efficacy of suture fixation of foldable intraocular lens (IOL) in ciliary sulcus guided by ultrasound biomicroscopy (UBM). Methods. Thirty-five eyes of 32 cases needing suture fixation of foldable IOL in ciliary sulcus in our hospital were collected and divided into two groups: group A and group B. In group A, UBM was performed on 19 eyes of 17 cases before ...

Dear Editor: I read the article “Epilens membrane simulating cataract in children with uveitis: a report of three cases” by Paiva et al. with great interest. Three cases were presented that were diagnosed as cataract secondary to uveitis but that were understood to have received treatment for pupillary membrane intraoperatively. I congratulate the authors for their attention and good management...

During a 2-year period, 31 cases of a hereditary retinal degeneration in dogs bred in India were found mainly suspected for progressive retinal atrophy (PRA) with typical history of initial nyctalopia followed by hemeralopia. Out of 31 PRA suspected dogs, 8 dogs (26%) were from the age group of 1-5 years, 15 (48%) 6-10 years and the rest (26%) 11-15 years. The most predominant breed was Spitz (...

AIMS To assess the intraocular pressure (IOP) lowering mechanism of deep sclerectomy with collagen implant (DSCI), a non-penetrating glaucoma surgery. METHODS Nine eyes of nine patients with medically uncontrolled open angle glaucoma underwent DSCI. Ultrasound biomicroscopy (UBM) of the sclerectomy site was performed 1 month after surgery. The following factors were assessed: length and heigh...
