OBJECTIVE To examine the relationship between anterior chamber (AC) sterilization and vitreous positivity rate in cases of endophthalmitis. DESIGN Retrospective case-control study. A review of all consecutive cases of endophthalmitis (N = 758) between January 1, 1999, and December 31, 2008, identified 229 matched AC and vitreous samples. Matched samples were evaluated for sensitivity and spec...

Radioimmunoassay with calf and cow vitreous humour-I125 and rabbit antivitreous humour serum has been employed to investigate the immunological cross-reactivity of vitreous humour with bacterial and mammalian tissue antigens. Klebsiella ultrasonicate preparation at a dose fo 10 000 micrograms/ml was found to inhibit the binding of vitreous humour by 25-100% (p less than 0.001), compared with an...

Optical coherence tomography is a non-contact imaging method of the anterior and posterior segments eye that based on laser scanning in spectral domain. This study presents diagnostic possibilities new generation Solix FullRange™ OCT&OCTA apparatus (Optovue) to examine meibomian glands, cornea, chamber, as well iridocorneal angles lens. In segment it allows for precise evaluation vitreous b...

AIMS Viral uveitis and retinitis, usually caused by herpesviruses, are common in immunosuppressed patients. The diagnosis of viral anterior uveitis and retinitis is usually clinical. The polymerase chain reaction (PCR) has been used for the diagnosis of some viral infections, especially those caused by herpesviruses. This paper reports the use of PCR in the diagnosis of viral retinitis in vitre...

UNIOCULAR aphakia is a condition of artificial anisometropia which very often causes great annoyance to the sufferer, who finds the aphakic eye of little use if the other eye is normal, and often complains of lack of binocular function and difficulty in judging distances, especially at close range. If contact lenses have been tried with unsatisfactoryresults, it seems justifiable especially in ...

OBJECTIVES A prospective study to evaluate the changes in A-Scan axial parameters of phakic normal eyes before and after instillation of 1% topical Tropicamide and 2% Homatropine eye drops. METHODS Anterior chamber depth, lens thickness, vitreous chamber length, and ocular axial length were measured in 76 eyes before and after cycloplegia induced by 1% topical Tropicamide, and in 28 eyes with...

After posterior capsule rupture, removal of residual lens material is a challenging but important goal. Sequential, interdependent strategies to accomplish this include the Viscoat PAL, the Viscoat Trap, bimanual pars plana anterior vitrectomy, and bimanual irrigation–aspiration of cortex. Once brought into the anterior chamber, the nucleus can be removed either with phacoemulsification above a...

By administering fluorescein intravenously to 95 patients we calculated the ratio of fluorescein concentration in the vitreous at the time of its peak level compared with the estimated unbound concentration of fluorescein in the plasma at the same time. We studied 12 normal phakic and 83 aphakic eye approximately two months, one year, and more than two years after cataract extraction. All the e...

One of the outstanding problems in ophthalmology to-day is the elucidation of etiological factors in the primary glaucomas, i.e., those not directly resulting from obvious pathological or anatomical defects of the eye. Our knowledge of the mechanisms productive of intraocular hypertension in such cases has been greatly augmented in recent years by the publications of Duke-Elder, Seidel, Magitot...

PURPOSE Central corneal curvature is known to vary with refractive error, but the relation between corneal topography and ametropia is less clear. The current study was conducted to determine whether a relation exists between corneal asphericity and myopia. Associations between corneal asphericity and each of the components of refraction also were examined. METHODS Corneal asphericity and api...
