A 6-day-old female baby with known diagnosis of congenital Zika infection was referred for ophthalmologic examination. The mother (37 years old) was referred for a pruritic rash, conjunctival hyperemia, and malaise at 12 weeks of gestation while still living in Venezuela. Upon arrival to Miami, Zika virus (ZIKV) exposure was confirmed during prenatal screening. At birth, due to the known exposure, a complete congenital ZIKV workup was performed, including brain ultrasound and MRI, which disclosed calcifications in the frontal lobe...

The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via ciliodestruction), tumors, and other pathologies...

INTRODUCTION: We present our experience on idiopathic intracranial hypertension (IIH), before and after the introduction of a specific diagnosis and management protocol. METHOD: A descriptive retrospective study was conducted on patients with IIH over a 25year period (1990-2015), comparing the last 7years (after introduction of the protocol) with the previous 18years. RESULTS: Among the 18,865 patients evaluated, there were 54 cases of IIH (29 infants and 25 children)...

BACKGROUND: Choroid detachment is a rare disease process that has a multitude of etiologies; usually related to recent ophthalmological surgery, eye trauma, corneal ulcers, or intraocular pressure-lowering agents. Point-of-care ocular ultrasound has high utility and accuracy in diagnosing pathology of the eye. CASE REPORT: We present a case of a patient who presented with vision loss caused by a choroid detachment diagnosed on point-of-care ultrasound because fundoscopic examination was limited due to cataracts...

The current study reports a case of a patient with a chronic myelocytic leukemic fundus lesion, initially diagnosed in the Department of Ophthalmology, Rizhao People's Hospital (Rizhao, China). A male, 23-years-of-age, presented with a dark shadow in the front of the right eye, accompanied with blurred vision for 3 days (visual acuity of right eye, 0.4; visual acuity of left eye, 0.6). In addition, the patient had experienced gingival bleeding for 2 years, and recurrent upper respiratory infections for 1 year...

We report two cases of patients presenting for elective surgery, in whom significant gastric contents were identified by performing fortuitous ultrasound examination of their antral area. The first patient presented for a day-case surgery scheduled under regional anesthesia. With his consent, ultrasound examination of the antral area was by chance performed within the context of training for this technique, showing significant solid contents in the stomach. The patient admitted that he had not respected preoperative fasting...

OBJECTIVE: Since 2005, in France, corticosteroid therapy is now widely used in Duchenne muscular dystrophy (DMD). This treatment has changed our practice of pediatric rehabilitation teams. We describe here our 10-year clinical experience in treating DMD patients by CS according to international guidelines i.e. prednisone 0.75mg/kg/day started from the plateau of motor function. MATERIALS/PATIENTS AND METHODS: We conducted a prospective study. Information was given on the expected effects and side effects...

We were challenged and delighted when Dr. Sharon Solomon, guest editor of this Retina Supplement, invited us to reminisce about caring for patients with common retinal disorders before there was access to the diagnostic and therapeutic tools that are readily available today. We agreed to confine our remarks to 3 common, but serious, conditions: age-related macular degeneration (Dr. Fine), diabetic retinopathy (Dr. Goldberg), and retinal detachment (Dr. Tasman). Each of us completed our ophthalmology training about half a century ago...

Conventional thermal therapy monitoring techniques based on temperature are often invasive, limited by point sampling, and are indirect measures of tissue injury, while techniques such as magnetic resonance and ultrasound thermometry are limited by their spatial resolution.  The visualization of the thermal coagulation zone at high spatial resolution is particularly critical to the precise delivery of thermal energy to epithelial lesions. In this work, an integrated thulium laser thermal therapy monitoring system was developed based on complex differential variance (CDV), which enables the 2D visualization of the dynamics of the thermal coagulation process at high spatial and temporal resolution with an optical frequency domain imaging system...

BACKGROUND: Literature reports on ophthalmological manifestations related to tularemia, a zoonose caused by the bacterium Francisella tularensis, largely refer to Parinaud's oculoglandular syndrome, which consists of the association of conjunctivitis with preauricular lymphadenitis. In this paper, we report a case of intraocular inflammation during tularemia infection. CASE PRESENTATION: A 52-year-old Caucasian man was diagnosed with unilateral uveitis. The uveitis was posterior, with a 2+ vitritis and a large yellowish lesion involving the macula with an overlying sub-retinal detachment, extending inferiorly, and subretinal hemorrhages...

Point of care ultrasound in the emergency department (ED) is increasingly being used to diagnose time-sensitive, vision-threatening conditions. We present a case of a 64-year-old female who presented to the ED with a three-day history of worsening left eye floaters. Point of care ocular ultrasound demonstrated a posterior chamber containing many echogenic opacities of varying size without acoustic shadowing. Movement of the eye resulted in significant after-movement of these opacities, giving the classic "washing machine" appearance seen with vitreous hemorrhage (VH)...

CDC has updated its interim guidance for U.S. health care providers caring for infants born to mothers with possible Zika virus infection during pregnancy (1). Laboratory testing is recommended for 1) infants born to mothers with laboratory evidence of Zika virus infection during pregnancy and 2) infants who have abnormal clinical or neuroimaging findings suggestive of congenital Zika syndrome and a maternal epidemiologic link suggesting possible transmission, regardless of maternal Zika virus test results...

INTRODUCTION: The incidence of facial cleft is rare and ranges between 1.43 and 4.85 per 100,000 births. To date, there have been few reports of detailed ophthalmologic examinations performed in cases of facial cleft. Here, we report a case of optic-nerve hypoplasia and anterior segment abnormality associated with facial cleft. CASE REPORT: A 9-day-old female infant was delivered by cesarian section at 34 weeks of gestational age (the second baby of twins) and weighed 2,276 g upon presentation...

AIM: To comprehensively analyze the risk factors of rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD). METHODS: A total of 265 eyes of 265 consecutive cases of RRD were retrospectively analyzed. All patients had systemic and ophthalmologic examination. CD was diagnosed by indirect ophthalmoscopy, B-scan ultrasonography, and ultrasound biomicroscope (UBM). Each parameter was compared between patients of RRD and rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD)...

BACKGROUND: Egypt has one of the highest prevalence of hepatitis C virus (HCV) worldwide. Ophthalmological side effects are recognized complications of interferon (IFN) therapy. This study aimed to evaluate IFN-induced ophthalmological manifestations in patients receiving PEGylated interferon (PEG IFN) and ribavirin (RBV) and to assess the effect of IFN duration, response and systemic risk factors on the severity. METHODS: We retrospectively analyzed 100 patients with chronic HCV who were candidates for PEG-IFN and RBV therapy...
