Five patients with ocular trauma due to elastic cords with attached metal or plastic hooks were evaluated over a 13-month period. Injuries included hyphema, angle recession, lens subluxation, choroidal rupture, vitreous hemorrhage, retinal detachment, and scleral rupture. Two patients suffered penetrating ocular injuries, and three patients had final visual acuities of 20/200 or less. This seri...

Surgical management of ectopia lentis is one of the major challenges faced by cataract surgeons today. Ectopia lentis signifies a displacement or malposition of the crystalline lens, irrespective of cause. It may occur congenitally or as part of developmental anomalies, as found in Marfan syndrome, homocystinuria, Ehlers-Danlos syndrome, hyperlysinemia, sulfite oxidase deficiency, simple primar...

HYPOTHESIS During total shoulder arthroplasty (TSA), humeral head subluxation may be difficult to manage. Furthermore, there is a risk for postoperative recurrence of subluxation, affecting the outcome of TSA. An accurate evaluation of the subluxation is necessary to evaluate this risk. Currently, subluxation is measured in 2 dimensions (2D), usually relative to the glenoid face. The goal of th...

Ectopia lentis continues to be a therapeutic challenge for ophthalmologists. It can occur as an isolated condition, after ocular trauma, in association with other ocular disorders, as part of a systemic mesodermal disease or as a complication of general metabolic disorders. Minimal subluxation of the lens may cause no visual symptoms, but in more advanced cases serious optical disturbances aris...

A 27-year-old woman with bilateral high myopia had anterior chamber iris-claw phakic intraocular lens implantation in her left eye under local anesthesia and with no intraoperative complications. The preoperative slit-lamp examination was normal, and she had no relevant past medical history. On the second postoperative day, patient developed fixed, dilated mydriasis, and one month later, an IOL...

the resistant* of patesa against lateral displacement (le. the stability), was studied tinder a range of conditions in vitro, at a range of knee flexion angles. muscle forces were applied in physiological directions along the separate quadriceps muscles. normal muscle actions with constant tension showed constant patellar stability up to sixty degrees knee flexion, and then a significant increa...

BACKGROUND The aim of this study is to determine the relationship between the cause of lens dislocation and visual outcomes with complications in patients undergoing trans pars plana vitrectomy (TPPV) and trans pars plana lensectomy (TPPL) for lens dislocation. METHODS This retrospective study was carried out from July 1995 through November 2003. After excluding patients with previous retinal...

The cervical spine radiographs of 100 patients with early rheumatoid disease were studied annually, on a prospective basis, for a mean follow-up period of 7 years 2 months. Atlantoaxial subluxation developed in 12 patients. The subluxation was more frequent in females, more severe in patients with progressive, seropositive, erosive rheumatoid disease, and more marked in patients treated with or...
