We describe a woman in whom bilateral orbital hemorrhage occurred during labor. She developed sudden proptosis and complete loss of vision bilaterally. After a stillbirth, she underwent total hysterectomy because of atonic uterus and postpartum hemorrhage. The location of the hematomas was confirmed by magnetic resonance imaging. Clinical resolution occurred in one month but both eyes remained ...

Imagine an observational technique, differential in nature, that takes full advantage of the information content a photon has to offer. Photometric conditions would be unecessary, allowing groundbased telescopes to outsrip their space-based counterparts for uses where imaging is not required. Indeed, such a technique has been around for decades in the form of polarimetry. Why, then, are the num...

Purpose. To evaluate the clinical features, microbiological spectrum, and treatment outcomes of endogenous endophthalmitis. Methods. Retrospective review of consecutive cases with infective endogenous endophthalmitis presenting from 2000 to 2007. The main outcome measure was the visual outcome at the latest follow-up visit. Other outcome measures included microbiological investigations, anatomi...

Abstract Introduction: Currently ocular combat injuries are complex and associated with poor visual outcomes. Our objective is to characterize the military population that suffer land mine combat ocular trauma in Colombia and indentify the type of wound, treatment and visual outcomes. Methods: Retrospectively review of medical history of soldiers evaluated in Pablo Tobon Uribe Hospital, whom ha...

AIM To study the anatomical and visual performance following implantation of a model of artificial cornea and to evaluate the postoperative long term complications. METHODS 11 eyes of 11 patients with bilateral corneal blindness considered as potentially having high risk of failure of penetrating corneal keratoplasty were implanted with biocolonisable Kpro keratoprosthesis (BIOKOP I, FCI, Ran...

BACKGROUND Vitreomacular adhesion can lead to pathologic traction and macular hole. The standard treatment for severe, symptomatic vitreomacular adhesion is vitrectomy. Ocriplasmin is a recombinant protease with activity against fibronectin and laminin, components of the vitreoretinal interface. METHODS We conducted two multicenter, randomized, double-blind, phase 3 clinical trials to compare...

PURPOSE In von Hippel-Lindau disease (VHL), retinal detachment is often a real threat if the retinal angiomas are left untreated. The aim of this trial was to diagnose and treat capillary angiomas early at an asymptomatic stage. METHODS Since 1983, we have investigated patients with key lesions and those who are at risk for VHL in a multidisciplinary study. Classical retinal angiomas and micr...

PURPOSE To evaluate interobserver test-retest reliability of the Teller Acuity Card procedure for assessment of grating acuity at ages 1, 2, 3.5, 4.5, and 5.5 years, for HOTV letter acuity at 3.5 and 4.5 years, and for Early-Treatment Diabetic Retinopathy Study (ETDRS) letter acuity at 5.5 years in the multicenter study of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP). METHODS Subject...

Nonverbal communication plays an important role in social interactions. However, most nonverbal communication relies on visual signals such as eye contact, head nods, facial expressions and body gestures. Visual nonverbal signals are inaccessible for the blind and hardly accessible for low vision individuals. In this paper, we present a qualitative study on nonverbal signals for the blind in fa...

A random sample of 9548 Palestinian Arabs living in the West Bank and Gaza Strip was identified, and 9054 (95.7%) were examined. Particular attention was directed to reduced visual acuity (VA) and its cause and to trachoma. Low visual acuity was defined as less than 6/18 in both eyes and binocular blindness as a VA less than 3/60 in both eyes. The overall incidence of low VA was 6.8% and of bin...
