Importance of CHB's grey zone: analysis of patients with HBeAg negative chronic hepatitis B virus infection.

Introduction: HBeAg-negative chronic HBV infection is defined by viremia < 2,000 IU/ml (or < 20,000 IU/ml), normal ALT activity and minimal liver fibrosis. Some patients do not meet all the criteria and belong to the so-called grey zone. The aim of the work was to analyse a group of patients with asymptomatic chronic HBV infection, divide them according to the levels of HBV DNA during follow-up and to compare the clinical and laboratory parameters of the patients within the groups.

Distribution and relevance of hepatitis B genotypes in the general population of Slovakia.

Aims: The aim of the presented study was to determine the distribution of HBV genotypes and their influence on selected parameters in patients in eastern Slovakia.

Methods: The study includes 202 patients with confirmed chronic HBV infection or hepatitis. For each patient, basic demographic data, and serum samples were collected.

Is Slovakia Almost a Hepatitis D Free Country?

LASER THERAPY OF RETINAL TEARS.

Aim: To report the clinical results of treatment of patients with retinal tears or holes, including rhegmatogenous retinal detachment, who were treated primarily with laser retinopexy.

Material And Methods: The effect and results of the therapy of patients with one or more retinal tears who underwent therapy with the green laser IQ 532 IRIDEX between December 2019 and August 2022 at our center with a follow-up observation period of at least 3 months were retrospectively evaluated.

Results: A total of 14 eyes of 14 patients were treated by this method during the monitored period.

CHELATION OF BAND KERATOPATHY IN LONG-TERM MONITORING.

Aim: To report the clinical results of chelation of band keratopathy in long-term follow-up.

Material And Methods: The long-term results of 5 patients (5 eyes) with symptomatic band keratopathy with a follow-up period of at least 6 months, in whom 2% EDTA was chelated on the affected eye in the study period from April 2018 to March 2021, were retrospectively evaluated. The follow-up period was 9-37 months.
