Purpose: To evaluate bioelectrical function of inner retinal layers measured by PERG in normal tension glaucoma.
Patients And Methods: In 50 eyes of 30 patients with normal tension glaucoma the following examinations were performed: history, routine ophthalmic examination, standard static perimetry and pattern ERG test.
Results: The most frequent abnormalities were incorrect N95/P50 amplitude ratio and increase latency of N95-wave.
Purpose: The goal of our study was to determine the value of electrophysiological tests in early and differential diagnosis of some hereditary retinal and optic nerve diseases.
Material And Methods: Review article on the basis of own experiences and results of another authors concerning to EOG, ERG, PERG, MfERG and VEP tests in evaluation of hereditary, stationary and progressive retinal diseases, as well as optic nerve diseases.
Results: Electrophysiological tests can be abnormal even in patients without fundus changes seen in routine ophthalmological examination.
Purpose: To assess the retinal function in BRCA1 gene mutation carriers.
Material And Methods: Thirty unaffected patients (60 eyes) with constitutional BRCA1 gene mutation were studied. Flash ERG recordings were performed in accordance with the International Society for Clinical Electrophysiology of Vision (ISCEV) standards.
Purpose: To evaluate the value of ophthalmological tests in detection of the optic neuropathy associated with pituitary tumours.
Material And Methods: 38 patients with pituitary tumours in 21-73 years old, were examined. Routine ophthalmological examination, kinetic and static perimetry (screening test, "white-on-white" and "blue-on-yellow") and PVEP were performed.
Localization and clinical characteristics of the ocular metastases of solid tumours are presented. Choroid is the most common localization site of these metastases, however they may involve each ocular structure. In the most cases they are diagnosed in patients with earlier recognized cancer, but in 12-40% of the patients ocular metastasis is a first sign of the neoplasm.
