[The influence of stimulation dopaminergic D, i D2 receptors in lateral geniculate body on flash visual evoked potentials (FVEP) in rats].

Purpose: The topic of this paper is to define the influence of stimulation dopaminergic D1 i D2 receptors in lateral geniculate body by flash visual evoked potentials (FVEP).

Material And Methods: Wistar rats were examined. There were stereotaxically implanted with guide caniula into the lateral geniculate body to inject substances and with VEPs electrodes on the skull and on the surface of visual cortex.

[The influence of dopamine injected into the lateral geniculate body on flash visual evoked response in rats].

Purpose: Numerous neurotransmitters and neuromodulators operating on all levels of the visual system, influence the parameters of cortical evoked response. The aim of this study was to find the influence of dopamine (DA) injected into the lateral geniculate body (nucleus) on flash visual evoked response (FVEP).

Material And Methods: The experiments were performed on adult Wistar rats.

[Visual evoked potentials (FVEP) after the prenatal exposure to heavy metals--experimentals studies].

Purpose: To find out, if any and how deep alterations in visual tract are due to prenatal intoxication by heavy metals such as: cadmium (Cd), lead (Pb), mercury (Hg) and manganese (Mn). The measure of these alterations were the changes in flash visual evoked potentials after prenatal intoxication.

Material And Methods: The experiments were carried out on 55 white newborns Wistar rats, which were divided into 5 groups: control group (14 rats), Cd group (12), Pb (6), Hg (14) and Mn (9).

[Quality of life in patients suffering from choroideremia].

Purpose: To direct attention on every-day problems in choroideremia, which are not a barrier in patients occupation.

Material And Methods: Two cases of patients with choroideremia which was diagnosed when they were 30 and 54 are described. In spite of widespread visual field changes patients with good visual acuity did not have to change their lifestyles or their jobs (miner and mechanic).

[Acute endophthalmitis of 15-year old boy in the course of acute lymphoblastic leukemia. Part II--Electrophysiological examinations].

Purpose: The aim of the study is to present objective estimation of visual function in eyes affected by leukemia.

Material And Methods: The boy who was described in the first part of this study was examined. Visual evoked potential (VEP), full-field flash electroretinography (FERG), electrooculography (EOG), were done according to ISCEV standards.

[Electroretinogram and electrooculogram in a family with Stargardt's disease].

Purpose: The aim of this study is to present the earliest functional changes in Stargardt disease in family with three affected and one unaffected children.

Patients And Methods: Four children: three girls (4, 7, 10, year old) and one boy (13 year old) and their parents (34 rear old mother and 36 year old father) were examined. Visual acuity (Snellen card), color perception (Ishihara's cards), electroretinography (flash full-field ERG--standard and chromatic) and electrooculography (EOG) were done.

[Short wavelength perimetry--the significance in diagnosis of glaucoma in myopic patients].

The static perimetry is the most useful diagnostic method in glaucoma. The aim of this paper is to compare the results of static short wavelength automatic perimetry (SWAP) with the classic one (white) in myopic patients with and without glaucoma. The Tubingen Automatic Perimeter was used, the threshold strategy within the central 30 degrees and glaucoma program was performed.
