[Anterior chamber migration of Supramid tube from short Krupin valves after more than 13 years of implantation. Two case reports].

Introduction: In 2004, the authors had to remove two short Krupin valves because the Supramid tube of these valves implanted 13 years previously had migrated into the anterior chamber.

Case Report: The first case was treated in April 2004, the second in November 2004. These valves had been implanted in January 1991 and August 1983 respectively; both because of insufficient, intense general and local medical treatments for vascular glaucoma: post-traumatic for one and neovascular glaucoma after central retinal vein occlusion for the other.

[Pellet guns: a persistent threat to eyes].

Following a recent case of bilateral perforating ocular trauma by multiple pellets, the authors reviewed pellet traumatisms treated in the Emergency Department and operated on in the Ophthalmology Department of the Villeneuve-St-Georges Hospital over the past 15 years. At close range, pellet weapon shootings can generate lid, conjunctiva, and powder cornea tattoos; in these cases, the lesions are often unilateral. Shooting at longer range does not result in corneodermic tattoos, but because pellets scatter, binocular lesions frequently occur.

[Air bags and eye injuries: chemical burns and major traumatic ocular lesions--a case study].

The authors report a case of bilateral eye lesions with extended visual sequelae after the inflation of a driver's airbag during a head-on collision. The superficial facial lesions were accompanied by bilateral eye lesions, reaching both the anterior and posterior segments. Bilateral periorbital palpebral hematomas; voluminous bipalpebral edema combined with severe -conjunctival edema, corneal erosions, and edema; bilateral hyphema; pupillary changes with multiple iris sphincter breaks and weak pupillary light reflex only on the right eye; retrocession of the iridocorneal angle; and on fundus examination both retinas had posterior and peripheral hemorrhages and Berlin retinal edema.

[Evaluation of moderate and severe visual impairments in patients attending an ophthalmology clinic. A prospective study of 1,172 patients].

Purpose: Data on blindness and visual impairment in patients attending ophthalmology clinics at the Orleans regional hospital center serving a semi-rural area in France were prospectively studied to examine prevalence of visual impairment.

Material And Methods: Clinical data on 1,172 consecutive and different patients attending the ophthalmology department during half-days over a 3-month period were collected and analyzed using a computerized system.

Results: Prevalence of visual impairment (20/30 or less in the better eye) was 3% in subjects under 60 years of age and rose to 13.

[Visual acuity and ocular diseases in aged residents of nursing homes: study of 219 persons in Orléans].

Purpose: To measure the visual acuity and to determine the etiological causes of visual impairment in the elderly residing in nursing homes.

Methods: 219 elderly persons residing in nursing homes were examined in the residence. The ophthalmological examination consisted in a visual acuity measurement, a slit-lamp examination and a fundus examination.
