A 59-year-old woman was seen by an ophthalmologist for blurred vision, ocular pain, headache, and nausea. She was diagnosed with acute primary angle closure (APAC) and successfully treated with medications. Using ultrasound biomicroscopy (UBM), engorged episcleral vein was observed and small uveal effusion was diagnosed after laser peripheral iridotomy (LPI). The uveal effusion disappeared and was again diagnosed by UBM together with anterior segment inflammation with ocular pain. Iritis caused by LPI after APAC might be a cause of uveal effusion in this specific case...

Canaliculops is a noninflammatory and noninfectious ectasia of the canaliculus with serous fluid accumulation. Currently, the etiology is uncertain. To the best of the authors' knowledge only 6 confirmed cases have been published earlier; however, the imaging features were not described. The authors report the ultrasound biomicroscopic and ocular coherence tomography features of a histopathologically proven canaliculops.

An 88-year-old woman with a history of complicated cataract extraction by phacoemulsification with sulcus intraocular lens (IOL) placement developed pseudophakic pupillary block after reverse implantation of the IOL. In the postoperative period, she had persistently elevated intraocular pressures (IOP) and was diagnosed with chronic angle-closure glaucoma that was treated medically. She presented 5 years later with acute pupillary block. The diagnosis of reverse IOL implantation was confirmed by ultrasound biomicroscopy...

PURPOSE: To report an unusual case of bilateral spontaneous scleral perforations. METHODS: A 34-year-old woman presented with bilateral conjunctival blebs and decreased vision in both eyes. There was no history of ocular trauma or surgery and no previous ophthalmic or systemic conditions that may have contributed to the scleral perforations. RESULTS: Best-corrected visual acuity was 20/40 in both eyes and intraocular pressures were 6 mm Hg in the right and 5 mm Hg in the left...

PURPOSE: Cysts of the iris pigment epithelium (IPE) can involve the pupillary margin, midzone, or peripheral location or can be free-floating in the aqueous or vitreous or lodged in the anterior chamber angle. Avariant of IPE cyst, known as iris flocculi, can be a marker for systemic thoracic aneurysm. DESIGN: Review of IPE cysts and description of new observations of the lesions. METHODS: Review of IPE cysts. RESULTS: Lesions in 672 eyes were classified as of the pupillary margin (n = 49; 7%), midzone (n = 188; 28%), peripheral (n = 424; 63%), or dislodged/free-floating (n = 11; 2%)...

BACKGROUND: Intravitreal injections are standard of care today and have the potential to change the anatomy of the anterior segment of the eye. This research was undertaken to evaluate the changes in anterior segment anatomy after intravitreal anti vascular endothelial growth factor (anti VEGF) injections. METHODS: We conducted a prospective interventional case series at a quaternary care center where patients undergoing intravitreal injection had pre and post injection ultrasound biomicroscopy (UBM) and intraocular pressure (IOP) measurement after intravitreal anti VEGF injection of 0...

PURPOSE: The aim of this study was to evaluate the safety and efficacy of deep sclerokeratodissection (DSKD), a new nonpenetrating technique in glaucoma surgery. MATERIALS AND METHODS: Retrospective comparison between patients treated with DSKS or deep sclerectomy (DS) between 2013 and 2014. In DSKD, the first and only flap is dissected directly into clear cornea with unroofing Schlemm's canal. Beside routine clinical follow-up (visual acuity, intraocular pressure [IOP] readings, slit lamp and fundus examination), postoperative ultrasound biomicroscopy (UBM) investigation and quality of life (QoL) assessment were performed...

INTRODUCTION: We herein report a case of bilateral unusually thick non-edematous keratoconic corneas with associated endothelial features of posterior polymorphous corneal dystrophy (PPCD). CASE REPORT: We report the case of a 27-year-old myopic woman who presented for refractive surgery. Slit lamp exam showed bilateral corneal protrusion with diffuse deep stromal and endothelial vesicular opacities and small paracentral bands. Topography showed generalized advanced corneal steepening in both eyes with increased anterior and posterior central corneal elevations in comparison to the best fit sphere...

PURPOSE: To report the clinical investigation of isolated microspherophakia involving a Senegalese family in order to appreciate its functional impact. OBSERVATIONS: This is a rural family comprised of 7 members. The sibship included three girls and two boys. One of the girls, who lived in a distant zone, was unable to be examined. Of all the examined members of the family, only the father was unaffected by the illness. There was no consanguinity. The general medical examination was normal...

OBJECTIVE: To evaluate the feasibility of ultrasound biomicroscopy (UBM) and tonometry in pigeons and to provide biometric reference ranges for normal pigeon eyes. ANIMALS STUDIED: Ten pigeons (Columba livia var. domestica) with ophthalmologically normal eyes. PROCEDURES: Ophthalmic examinations, including slit-lamp biomicroscopy and tonometry, were performed to confirm that the eyes were normal. UBM was then performed on the left eye. On each obtained image, the ciliary cleft (CC) length, CC width, and CC area, and iridocorneal angle (ICA) were measured...

PURPOSE: Trabeculectomy has been regarded as a mainstay of initial treatment in eyes of angle closure glaucoma (ACG) with peripheral anterior synechia > 180° in the Chinese population while its efficacy in secondary ACG with BEST1 gene mutation remains unclear. We set out to investigate the treatment outcome of trabeculectomy for secondary ACG in a group of patients with autosomal recessive bestrophinopathy (ARB). METHODS: In this retrospective case series study, 8 secondary ACG patients with ARB and their 4 recruited family members underwent a thorough ophthalmic examination including best-corrected visual acuity, Goldmann applanation tonometry, gonioscopy, and fundus examinations...

PURPOSE: To compare the movement of a modular intraocular lens (IOL) with that of a standard single-piece hydrophobic acrylic IOL in a human cadaver eye perfusion model. SETTING: Department of Ophthalmology, University of Colorado, Aurora, Colorado, USA. DESIGN: Experimental study. METHODS: Eight phakic human donor eyes of 4 patients had standard phacoemulsification with lens removal. One of 2 IOLs was then implanted in the capsular bag: a modular IOL (Harmoni) or a standard single-piece IOL (Acrysof SN60)...

PURPOSE: To report the results and complications of scleral buckling for the treatment of rhegmatogenous retinal detachment (RRD) using 25-gauge chandelier endoillumination. METHODS: A total of 61 patients (61 eyes) with RRD were treated with scleral buckling.

PURPOSE: To describe IOL haptic with iris or ciliary body touch on ultrasound biomicroscopy (UBM) in pseudophakic patients with unexplained recurrent hyphema or vitreous hemorrhage. METHODS: Retrospective chart review of 10 patients who presented with unexplained recurrent hyphema and or vitreous hemorrhage. RESULTS: There were eight posterior chamber intraocular lenses (PCIOL) and two sulcus lenses. Four cases had a history of glaucoma; two cases which had a history of trabeculectomy were found to have some bridging vessels along the sclerostomy requiring argon laser gonioplasty...

AIM: To analyze changes in various biometric parameters after vitrectomy. MATERIAL AND METHODS: A total of 50 patients (50 eyes) were followed up. All of them underwent vitrectomy for idiopathic epiretinal fibrosis and macular hole. In addition to the standard ophthalmic examination, we performed a combined ultrasound study and ultrasound biomicroscopy before and after the surgery (at 2-3 weeks and 6 months). Variation statistics was applied to assess the results using the SPSS Statistica 20 software...
