The rates of accumulation of C-14-labeled alpha aminoisobutyric acid (a-AIB) in the aqueous and vitreous humors and lenses of rabbit eyes following parenteral administration have been determined. The distribution ratios of a-AIB in the aqueous humor of the posterior and anterior chambers, the vitreous humor, and the lens 24 hours after parenteral administration were found to be 0.75, 0.98, 0.1,...

Anomalous posterior vitreous detachment (PVD) plays a major role in the formation of anterior-posterior and tangential epiretinal traction. Advances in the tomographic analysis of vitreous traction vectors have highlighted the selected cases that can benefit from " parasurgical " approaches, providing a different perspective for therapeutic strategies. The symptomatic anterior-posterior tractio...

THE occurrence of crystals in the anterior chamber of the eye is extremely rare. Parfait-Landrau (1828) first reported the presence of crystals in the living eye. Schmidt (1831) observed a shower of silver and gold dust gush forth when he opened the anterior chamber of an eye blind for years. Blasius (1852) mentioned that 24 cases had been reported, rather a large number considering the rarity ...

PURPOSE To report the role of Healon5 injection combined with medications in patient with malignant glaucoma after trabeculectomy with unplanned zonulectomy. METHODS Two days after trabeculectomy with unplanned zonulectomy for neovascular glaucoma in an eye with diabetic retinopathy, a patient developed malignant glaucoma due to the ciliovitreal block caused by the vitreous herniation through...

BACKGROUND To evaluate the surgical results of patients with persistent fetal vasculature (PFV), also known as persistent hyperplastic primary vitreous (PHPV). METHODS From 1991 to 2001, a retrospective, noncomparative study of 7 eyes of 7 patients diagnosed with PFV was conducted. In each case, type of anterior and/or posterior PHPV findings, preoperative testing, surgical procedures, and vi...

glaucoma. It is now recognised to comprise the diagnostic triad of a diffusely flat anterior chamber, high intraocular pressure, and aqueous pooling that is sometimes visible in or in front of the anterior vitreous. Malignant glaucoma is notoriously difficult to treat and carries a generally poor prognosis for long term control of intraocular pressure. It is thought to involve the mechanisms of...

OBJECTIVE To determine the prevalence of ocular findings of the external structures and anterior segment of the eye, detected by biomicroscopic examination in schoolchildren in Natal (RN)-Brazil. METHODS After previous random selection, 1,024 pupils from elementary and secondary public and private schools in the city of Natal were evaluated from March to June 2001. All were submitted to prees...

We report an 83-year-old immune-competent female with unilateral endophthalmitis extraordinarily caused by cytomegalovirus (CMV). Since she was suspected of suffering possible bacterial endophthalmitis, she was referred to our hospital. At the first visit, hypopyon in the anterior chamber and the opacity of vitreous body were observed in the left eye. The best-corrected visual acuity (BCVA) of ...

Marfan’s syndrome (MFS) is an autosomal dominant connective tissue disorder involving the cardiovascular, skeletal and ocular systems.Cardinal manifestations include aortic aneurysm and dissection, ocular lens dislocation and long bone overgrowth. The most common cause of ectopia lentis is trauma, which accounts for nearly onehalf of all cases of lens dislocation. A forward dislocation of the l...
