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...

OBJECTIVE: Slit-lamp ophthalmologic examination and ocular B-scan sonography of the globe are frequently constrained by technical limitations in the setting of traumatic orbital injury. The main purpose of this study was to evaluate the diagnostic performance of CT in acute anterior segment ocular injuries as an adjunctive diagnostic modality. MATERIALS AND METHODS: We retrospectively identified 122 patients who presented to the emergency department from April 2011 through April 2016 with recent direct trauma to the anterior segment of the eye...

PURPOSE: The aim of the study was to identify potential failure modes (FMs) having a high risk and to improve our current quality management (QM) program in Collaborative Ocular Melanoma Study (COMS) ocular brachytherapy by undertaking a failure modes and effects analysis (FMEA) and a fault tree analysis (FTA). METHODS AND MATERIALS: Process mapping and FMEA were performed for COMS ocular brachytherapy. For all FMs identified in FMEA, risk priority numbers (RPNs) were determined by assigning and multiplying occurrence, severity, and lack of detectability values, each ranging from 1 to 10...

Background Advanced cataract with hard lens nuclei frequently challenge the ophthalmologic surgeon when doing phacoemulsification. In the present study, we examined the effect of a new phaco tip design during cataract surgery. Patients and Methods 100 patients were assigned to two groups. In group 1 (50 patients), the Kelman(®) tip design (Alcon) was used during phacoemulsification, while in group 2 (50 patients), the Intrepid(®) Balanced Tip was applied. Trypan blue was used in both groups, if necessary, to stain the anterior lens capsule prior to capsulorhexis...

BACKGROUND AND STUDY AIMS: Neonatal cholestasis can be associated with ocular findings that might aid in its diagnosis, e.g., Alagille syndrome (AGS) and Niemann Pick disease (NPD). We aimed to investigate the frequency of ocular manifestations in infants with cholestasis. PATIENTS AND METHODS: This cross-sectional study included cholestatic infants presenting to the Paediatric Hepatology Unit, Cairo University Paediatric Hospital, Cairo, Egypt. All infants underwent examination of lid, ocular motility, anterior and posterior segments and measurement of intraocular pressure, cycloplegic refraction, ocular ultrasonography and vision...
