BACKGROUND: To determine the agreement of central corneal thickness (CCT) measurements taken with ultrasonic pachymetry (USP), spectral domain optical coherence tomography (SD-OCT) and noncontact specular microscopy (NSM). METHODS: A prospective, observational, cross-sectional study was performed in the outpatient ophthalmology clinic. CCT was measured in a total of 147 eyes of 147 consecutive healthy patients with USP, NSM, and SD-OCT. Same examiner performed all examinations...

PURPOSE: To report the case of a 65-year-old metalworker with no known history of ocular trauma, who suffered from intense ocular pain during magnetic resonance imaging (MRI) of the brain, due to a retained intraocular metallic foreign body (IOFB). CASE REPORT: Meticulous ophthalmological examination was inconclusive. An IOFB was confirmed with X-ray scan, whereas its exact localization was enabled by means of ultrasonography and ultrasound biomicroscopy (UBM). CONCLUSIONS: Despite appropriate screening protocols, MRI-related ocular complications might occur in the presence of a hidden metallic IOFB...

A 9-year-old girl was reviewed by a tertiary ophthalmology service after being hit in her right upper eyelid by a fish whilst swimming. Initial wound exploration demonstrated fish scales in the wound. She was first treated conservatively with washout of the 5-mm wound and was discharged with oral ciprofloxacin. Five days later, the patient re-presented with a worsened ptosis due to periorbital swelling. Ultrasound of the upper lid demonstrated a foreign body in the upper lid. The patient was taken to theatre and, with the assistance of intraoperative ultrasound, the jaws of a needle fish were removed from the upper lid...

Retinal detachment is an ophthalmologic emergency that requires immediate medical attention as it can potentially lead to permanent vision loss. The gold standard for diagnosing retinal detachment is dilated funduscopic exam. However, when this exam is not feasible such as in an emergency room setting or if visualization of the posterior portion of the eye is not possible due to vitreous hemorrhage or dense cataracts, ocular ultrasound provides a readily available and effective alternative. We present the sonographic appearance of chronic retinal detachment in a 24-year-old female with a longstanding history of poorly controlled type 1 diabetes who could not undergo dilated funduscopic exam due to intra-ocular hemorrhage...

PURPOSE: The aim of the study was to evaluate the bacterial contamination level of contact surfaces on slit lamps and the grip areas of lenses. METHODS: Within unannounced audits, two regions of the slit lamps (headrest and joystick), indirect ophthalmoscopy devices, and ultrasound probes were obtained with rayon-tipped swab. Non-contact lenses used for indirect fundoscopy were pressed on RODAC (Replicate Organism Detection and Counting) plates. One hundred and eighty-one surfaces were sampled...

METHODS: A chart review was performed of patients who had transscleral fixation of IOLs between January 1, 2012, and December 31, 2013. Eyes were divided into 2 groups depending on whether the IOL was pupillary captured...

A 39-week-old male newborn presented at birth with atrophic erythematous and purpuric skin lesions, in a typical right-sided segmental distribution. Lesions were persistent and unaffected by rewarming in the postpartum period. Postnatal echocardiogram showed a predominance of the right cavities and an upper atrial septal defect. Cerebral and abdominal ultrasound were normal along with ophthalmological examination. On follow-up, lower limbs asymmetry was noted. The right lower limb was shorter in length and had a smaller diameter...

The aim of this study was to evaluate the feasibility of ocular ultrasound in the follow-up of pseudotumor cerebri syndrome and to correlate ultrasound with clinical parameters. In a cohort study of 22 consecutive adult patients, ocular ultrasound was performed measuring optic nerve sheath diameter, optic nerve diameter, and optic disc elevation compared with symptoms referred by the patients. The patients showed increased optic nerve sheath diameter [median, 6.51 mm (interquartile range 6.13-7.10)], optic nerve diameter [3...

PurposeTo describe the ocular and systemic phenotype in IQCB1-related disease.MethodsFour cases (3 males, 1 female) with molecularly confirmed IQCB1-related disease underwent ophthalmological examination including best-corrected visual acuity (BCVA) measurement, fundus evaluation, electroretinography (ERG), and spectral-domain optical coherence tomography (SD-OCT). Systemic evaluation including abdominal ultrasound was performed in all cases.ResultsBCVA ranged from perception of light (Case-2; 1 year) to 20/125 (Case-1; 9 years)...

PURPOSE: To evaluate B-mode ultrasound as a novel method for the examination of pupillary function and to provide normal values for the pupillary reflex as assessed by B-mode ultrasound. METHODS: 100 subjects (49 female, 51 male, mean [range] age 51 [18-80 years]) with no history of ophthalmologic disease, no clinically detectable pupillary defects, and corrected visual acuity ≥ 0.8 were included in this prospective observational study. B-mode ultrasound was performed with the subjects eyes closed using an Esaote-Mylab25 system according to current guidelines for orbital insonation...

Purpose: To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods: Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body...

Objective: To examine the features and values of ultrasonic diagnosis for retinal detachment in eyes with silicone oil tamponade (SOT). Methods: A prospective study. A total of 257 eyes (257 patients) were filled with silicone oil between December 1, 2015 and August 1, 2016 in the Department of Ophthalmology at a hospital in Beijing. All of the patients underwent a color Doppler ultrasound examination in the supine and sitting positions a week prior to surgery. The pre-surgery conditions were compared with the subsequent observations during the surgery to analyze the features and values of ultrasonic diagnosis for retinal detachment in eyes with SOT...

PURPOSE OF REVIEW: We review new applications of optical coherence tomography (OCT) technology in neuro-ophthalmology. We also describe new technologies for visualizing the extracranial vessels in the diagnosis of giant cell arteritis (GCA). RECENT FINDINGS: Newer OCT modalities are expanding the evaluation of the optic disc, and are being applied to a number of neurologic conditions such as demyelinating and neurodegenerative disease. Swept-source OCT and enhanced-depth imaging OCT are refining the fine-grained analysis of the optic nerve head in the diagnosis of papilledema and optic nerve drusen...
