An ophthalmoscope is used to view the fundus or interior of the eye.
To turn on the ophthalmoscope, depress the red button and turn the black ring. Do not use an intense light when looking into your lab partner's eye. Set the diopter window to read "0." Your lab partner will need to look straight ahead without blinking. Hold the ophthalmoscope next to your eye so that you can see through the viewing aperture. While looking through the viewing aperture, move from the lateral side of your lab partner's eye toward the medial aspect so that you are "cheek to cheek." This will minimize the photopupil reflex and direct your attention towards the optic disk. The optic disk has blood vessels radiating from it. By moving toward the middle of the eye, you may be able to locate the macula lutea.
