A 68-year-old man developed right homonymous hemianopic paracentral scotomas from acute infarction of the left extrastriate area. He was studied over the ensuing 12 months with visual fields, conventional MRI, functional MRI (fMRI), and diffusion tensor imaging (DTI). As the visual field defect became smaller, fMRI demonstrated progressively larger areas of(More)
PURPOSE To evaluate the intraoperative complications and postoperative results of bimanual phacoemulsification and aspiration using a sleeveless phaco tip inserted through an ultra-small incision. SETTING Department of Ophthalmology, Jikei University, Tokyo, Japan. METHODS This study comprised 637 eyes having cataract extraction using conventional(More)
Rice-infecting viruses have caused serious damage to rice production in Asian, American, and African countries, where about 30 rice viruses and diseases have been reported. To control these diseases, developing accurate, quick methods to detect and diagnose the viruses in the host plants and any insect vectors of the viruses is very important. Based on an(More)
Purpose. This study retrospectively analyzed the postoperative visual functions of myopic eyes implanted with multifocal intraocular lens (IOL) to evaluate the efficacy of multifocal IOL in highly myopic eyes. Methods. We studied 61 patients (96 eyes) who were implanted with multifocal IOL ZMA00 or ZMB00 (Abbott Medical Optics). The patients were stratified(More)
An 84-year-old woman presented with a 3-month history of conjunctival chemosis in the left eye. At the first examination, the chemosis neighbored the lacrimal caruncle and was localized in the inferomedial region of the conjunctiva. During eyelid closure, only the left lacrimal caruncle was exposed. One month later, the chemosis further extended to the(More)
PURPOSE To describe a technique for intraocular lens (IOL) implantation that lessens the degree of surgical invasiveness by implanting a tightly rolled IOL through a small incision without touching the eye with the cartridge tip. METHODS An IOL was inserted through an incision by first allowing the leading haptic to protrude slightly from the cartridge(More)
PURPOSE To examine the influence of the configuration of prefilled syringes on the usability of ophthalmic viscosurgical devices (OVDs). SETTING Department of Ophthalmology, Jikei University School of Medicine, Tokyo, Japan. DESIGN Experimental study. METHODS The maximum force needed to extrude the whole OVD (extrusion force) was compared among(More)
UNLABELLED We describe a trisection technique for extracting a dislocated IOL through a small surgical incision. The dislocated IOL is brought into the anterior chamber and cut into 3 equal segments, with a negligible risk for the segments falling into the vitreous cavity.

PURPOSE To report a case of button battery-induced alkaline burn injury of the cornea and conjunctiva, with experimental findings of local damage. CASE A three-year-old girl had a hard and polished white opacity on the nasal lower cornea and conjunctival injection, caused by a button battery remaining in the conjunctival sac for several hours. The ocular(More)
