INTRODUCTION Elevated intracranial pressure (ICP) is a major and potentially lethal disorder in patients admitted to the emergency department (ED). Several methods are being used to investigate for elevated ICP. Here we assessed and compared the diagnostic accuracy of two existing tools of ophthalmoscopy and optic nerve ultrasonography in detection of elevated ICP. METHODS 131 participants wi...

Traveling to high altitudes can expose the eye to reduced ambient cold and low-pressure environments. These conditions can affect the physiology of the eye and may result in ocular problems and visual disturbances. In this paper, ocular disorders related to high altitudes are briefly reviewed. Then, high-altitude ocular disorders are categorized in three parts: those related to dry and cold env...

We report the case of a 32-year-old man suffering from intraocular cysticercosis, with special emphasis on the use of B-scan ultrasound in the diagnosis and management of the condition. An 8000 B-Scan Scanmate was used to obtain the ultrasound images. The patient had worked on a pig farm a few years before presentation. He presented with shadows seen in the right eye. Binocular indirect ophthal...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

Background: Behcet syndrome is a recurrent inflammatory disorder that frequently involves the ocular system. The purpose of this study was to determine the frequency of ocular involvement in cases of Behcet's disease in Babol, north of Iran. Methods: From April 2003 to December 2009, 100 cases of behcet's disease who were admitted at the Department of Ophthalmology and Internal Medicine of Babo...

PURPOSE This study re-examined an earlier claim that monocular patching during subjective night (i.e. patched at the usual time that night would occur) in the chicks reared in continuous lighting (CL), offered unpatched eyes some protection from the ocular effects of CL. It also examined whether this monocular patching protected unpatched eyes against the disruptive effect of CL on compensation...

PURPOSE To investigate whether myopia is present in a breed of domestic dog, the Labrador retriever, and how the ocular components are related to refractive error in this breed. METHODS Cycloplegic refractive error was measured in 75 Labrador retrievers by retinoscopy. Corneal and crystalline lens radii of curvature were measured in the right eyes of 57 of these dogs using a video-based kerat...
