What is an electrical engineer?

Electroretinogram is a diagnostic eye test that evaluates the functional ability of photoreceptors sensitive to the lights of the eye, rods and cones and their linking nerve cells in the membrane detecting the light of the eye, retina. During the examination, the ophthalmologist is the location of the electrode on the cornea, the clear window in the front of the eye to measure the electrical reactions of the rods and cones to the light. During the electroretinogram, the patient monitors the standardized display of light and bars and cone creates electrical pulses that are measured by electrode, with amplitude and duration. Two types of analysis are possible using two types of visual stimuli, including stroboscopic flashes for lightning electrical engineering and alternating chessboard patterns for the electrical engineering pattern. The abnormal electroretinogram suggests dysfunction of retinal photoreceptors due to hereditary conditions, such as the electricityinogram, lies or sit in a comfortable position such as arteriosclerosis, retinal separation or lack of vitamin or lack inITAMIN or Lack of vitamin and or deficiency of vitamin A or deficiency of vitamin and or deficiency of vitamin and or deficiency of vitamin and or deficiency of vitamin and or deficiency of vitamin and or deficiency vitamin and or lack of vitamin or deficiency of vitamin and or vitamin deficiency or lack of vitamin. The obtaining drops are then placed in the eyes. With the open lids with a speculation, the electrode on each eye is slightly located by a device similar to contact lenses and another grounding electrode is located on the skin. Each electrode then transmits information about the electrical activity of the rods and cones to the monitor.

Electroretinogram contains two parts. There is an initial wave that diverts down and represents photoreceptors converting light into an electrical signal. Second wave, b-vlny, behindcurvature up above the baseline. Bipolar and amacrine cells, other nerve cells in the retina, produced-rod. By examining these waves in relation to each other, specific types of diseases can be determined.

Lightning electroretinogram is used to determine the health of cone and rod cells. The patient's eyes are first adapted to the light by sitting in a normally lit room. The flash electrical engineer performed on the eye adapted to light will show the activity primarily formed in cone cells. The patient then sits in a matte room for 20 minutes and produces dark adapted eyes. Performed after dark adaptation, lightning electroretinogram will reflect the activity of rod cells.

Connecting nerve cells, ganglia cells, are evaluated by means of an electro -line pattern pattern. Checkerboards of white and black squares alternate so that each square in rapid sequence changes from white to black. Electrical pulses recorded on ERG indicate whether gangli cells work normalE. The sample sample electroretinogram can be used in rating ofglaukoma, optical nerve disease characterized by increasing intraocular pressure and slowly progressive death of ganglium cells of the retina.
