Study Notes
Retinoscope Components and Functions
- The main function of the projection system in a retinoscope is to project a beam of light onto the patient's eye.
Optical Head
- The optical head of a retinoscope projects a streak of light onto the retina.
Control Components
- The sleeve is responsible for controlling both meridian and vergence in a retinoscope.
Light Streak Manipulation
- Rotating the sleeve of a retinoscope affects the orientation of the light streak.
Observation System
- The purpose of the observation system in a retinoscope is to magnify and observe the reflection of the light streak from the retina.
Light Path
- The illumination system passes light through a condensing lens to focus rays onto a mirror in a retinoscope.
