Simulator Training for Direct Ophthalmoscopy

Study Overview
=================
Brief Summary
-----------------
Evaluation of a digital simulator to train diagnostic skills in Ophthalmology

Detailed Description
-----------------
Direct Ophthalmoscopy is an important tool to detect pathologies e.g. on the optic nerve head. The training of the needed skills is made conventionally in most cases. In such the training sessions students examine each other after dilating one pupil. Examining of patients with pathologies is very important, but in many cases not very easy without any experience. Simulators are of growing impact to teach diagnostic or surgical skills. A digital simulator with virtual reality technology is used to teach the skills to unexperienced examiners. The head-eye-hand-coordination can be trained without any stress.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total examined area | The area that was examined (light on retina) by participants was measured [percent of total area]. | 1 hour | 
| Efficiency | Ratio of examination time (light in pupil) and total examined area [ratio] | 1 hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
