Recruitment & Eligibility

Status: Withdrawn

Sex: Not specified

Target Recruitment: 25

Inclusion Criteria

The participants must be at least 18 years old to participate in the study.
It*s important to measure only healthy participants. This way the correct data
will come foward for the normal values.
This is because the results of the study should be representative for the
normal healthy population. The term healthy is defined as the absence of a
known eye or nerve condition that impairs visual acuity, such as cataracts,
diabetic retinopathy or glaucoma. It is important that the participant has a
visual acuity of at least 0.4.

Exclusion Criteria

Participants under the age of 18 can not participate in the study. Participants
with a visual score < 0.4 and/or eye complaints such as: blurred, double or
reduced vision are also excluded. Participants with diabetes mellitus are
excluded from the study because diabetes mellitus can affect nerve pathways.

Primary Outcome Measures

Name	Time	Method
<p>With this test, the normal values of healthy adults are determined during the<br /><br>PVEP test for the research set-up of the KNF department. The P100 latency times<br /><br>are considered. To calculate the normal values of the PVEP study performed on<br /><br>an LCD screen, the mean and the spread of the values **around the mean will be<br /><br>determined.<br /><br><br /><br>In the literature will investigate the difference between a CRT and LCD screen<br /><br>and whether this causes changes in the latency time of the P100 component. The<br /><br>influence of gender and age on the P100 latency times of the PVEP study will<br /><br>also be investigated in the literature.</p><br>
