BACKGROUND Differentiation between infectious and non-infectious uveitis is of crucial value for accurate management of patients with uveitis. Tests performed on aqueous humour yield more relevant information than those done in serum. The objective of this study was to evaluate whether the aqueous humour tap for diagnostic purposes is a safe procedure to perform in uveitis patients. METHODS I...

PURPOSE To investigate the optimal strategy for surgical management of traumatic cataract with posterior capsular rupture. METHODS We describe four cases of traumatic cataract with posterior capsular rupture and an in vitro model built to evaluate the optimal infusion pressure during surgery. RESULTS All patients underwent cataract surgery. By using an anterior chamber maintainer to elevate...

CASE REPORT A 78-year-old man with phakic eyes underwent photodynamic therapy followed by intravitreal injection of triamcinolone. During the injection a white solution was observed in the anterior chamber. Slit lamp examination revealed white opacities in the inferior anterior chamber angle and neither inflammatory activity nor corneal changes were noticed. DISCUSSION Intravitreal triamcinol...

The aim of this work was to analyse the pressure inside the eyes anterior chamber, namedintraocular pressure (IOP), in relation to the biomechanical properties of corneas. The approach used was based on the constructal law, recently introduced in vision analysis. Results were expressed as the relation between the temperature of the ocular anterior chamber and the biomechanical properties of the...

Delayed suprachoroidal hemorrhage (DSCH) is a rare but devastating complication of trabeculectomy, usually resulting in a poor visual prognosis. The typical presentation of DSCH includes acute visual loss, high intraocular pressure, a shallow anterior chamber, and choroidal elevation. We report a patient with hypertension who had DSCH following trabeculectomy, with an unusual presenting picture...

Fresh surgical specimens of retinoblastoma were successfully transplanted into the anterior chamber of the "nude" mouse (a homozygous mutant, nu/nu, with a severe defect in cellular immunity), filling the eyes but failing to grow subcutaneously. Retinoblastoma cells from an established cell line, Y-79,1 spread from the intraocular injection site to invade the orbit, optic nerve, and brain and f...

Ultrasound biomicroscopy is a non-invasive imaging technique, which allows high-resolution evaluation of the anatomical features of the anterior segment of the eye regardless of optical media transparency. This technique provides diagnostically significant information in vivo for the cornea, anterior chamber, chamber angle, iris, posterior chamber, zonules, ciliary body, and lens, and is of gre...

The use of antibody to vascular endothelial growth factor to treat neovascular glaucoma yields good anatomic results in most cases. However, this type of glaucoma can cause angle closure with decompensation of intraocular pressure secondary to fibrovascular tissue contraction in the anterior chamber. Our surgical technique treats the cause by removing the anterior chamber fibrous complex after ...

The ascorbic acid concentration in the posterior and anterior chambers of the rhesus monkey (Macaca mulatta) eye was determined, and found to be significantly higher in the posterior chamber. Monkeys anesthetized with pentobarbital sodium had a higher posterior chamber ascorbic acid concentration than monkeys sedated with phencyclidine. The ascorbic acid diffusion coefficient, calculated from t...
