Uveal melanoma - testing of abnormalities of chromosome 3 and 8 in the Czech Republic.

Aim: The aim of this cytogenetic study is to confirm the significance of chromosome 3 loss (monosomy 3) and of the gain of chromosome 8 as prognostic markers in histopathological samples of enucleated eyes with uveal melanoma in the Czech population.

Methods: This is a retrospective study of 52 enucleated eyes. Chromosome 3 and 8 status were tested by CISH, and in a few samples FISH was used.

[The use of telemetric intracranial pressure monitoring in the differential diagnosis of idiopathic intracranial hypertension - a case report].

Idiopathic intracranial hypertension is a disorder that results from an increase of intracranial pressure with unknown cause. A single measurement of intracranial pressure only provides data at one given point in time. Therefore, telemetric monitoring of intracranial pressure was performed in a patient with fluctuating headache and significantly impaired vision, which together accounted for 226.

[The ERG contribution in early diagnosis of chloroquine and hydroxychloroquine maculopathy].

Derivates of chloroquine (Plaquenil, Delagil), used for long-term treatment of rheumatic diseases, may cause clinically proven irreversible maculopathy, which may progress even after the discontinuation of their application. The optimal early diagnosis of ocular toxicity of chloroquine or hydroxychloroquine drug remains controversial up to now. The aim of this review paper was to evaluate how appropriate is the indication of the electroretinographic (ERG) examination due to the early diagnosis of cumulative drug-related maculopathy.

[Immunohistochemical detection of the gene p53 and p21 expression in cells of the malignant melanoma of the uvea].

Aim: To examine by means of immunohistochemistry the expression of the tumor suppressing gene p53 and gene p21 in cells of malignant melanoma of the uvea from formalin-paraffin material from patients, who were during the period 2000 - 2006 surgically treated due to malignant melanoma of the uvea at the Department of Ophthalmology in the University Hospital in Brno (Brunn), Czech Republic, E.U., and to correlate the results of the immunohistochemical detection with clinical signs of the tumor of each patient.

[Malignant melanoma of the uvea in the Department of Ophthalmology, Faculty Hospital Brno Bohunice, Czech Republic, EU].

Purpose: The malignant melanoma of the uvea (MMU) is the most common intraocular tumor among adults. The aim of the retrospective study was to evaluate the stage of the malignant melanoma of the uvea (MMU) at the time of diagnosis in a group of patients, to whom it was diagnosed in the Department of Ophthalmology, Faculty Hospital Brno. In the years 2005 and 2006, there had been diagnosed the MMU in 19 patients (11 women and 8 men) with the average age of 64.
