Postnatal ocular toxoplasmosis in immunocompetent patients.

Introduction: Ocular toxoplasmosis is the most common cause of infectious posterior uveitis worldwide. It can be prenatal or postnatal in origin. Despite estimations that postnatal ocular toxoplasmosis is more prevalent, only several cases of proven postnatal ocular toxoplasmosis have been reported in non-epidemic settings.

Utility of angiotensin-converting enzyme activity in aqueous humor in the diagnosis of ocular sarcoidosis.

Purpose: Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis.

Methods: We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement.

[The relation between the thickness of retrobulbar part of the optic nerve, measured by ultrasound, and the degree of prominence of the optic disc in stasis of the optic nerve].

Introduction: The etiology of the noninflamed edema of the optic disc, or the stasis of the same, is related to a large number of various illnesses which result in the increased intracranial pressure. When examining fundus, an edema of the optic disc is found which can be quantitatively expressed in diopters, while retrobulbar part of the optic nerve can be measured by ultrasonography.

Objective: The objective of our [Serbian characters: see text] is to explore the relation of the optic disc prominence and the degree of thickness of retrobulbar part of the optic nerve.

Helicobacter pylori: an underestimated factor in acute anterior uveitis and spondyloarthropathies?

Acute anterior uveitis (AAU) is the most common form of intraocular inflammation, but its aetiology is still unclear. Fifty percent of AAU patients are HLA-B27-positive, and half of these also have spondyloarthropathies (SpA). Numerous serological studies have shown elevated levels of serum antibodies to various Gram-negative bacteria in HLA-B27-positive AAU and SpA patients.
