Instructions for Conducting an Exam
1. FOCUS Start by removing your eyeglasses (recommended). Begin by focusing across the room on an object at least 10 feet away – the image should be clear and sharp.
2. SET TO SMALL SPOT For optimal undilated viewing, aperture dial should be placed on the small aperture (green line) position Turn scope on (using any Welch Allyn 3.5v power source). Adjust light intensity rheostat to maximum position. Continued on back.
3. EXAM POSITION Position yourself about 6 inches away and at a 15 to 20 degree angle on the temporal side of your patient Looking through the scope, shine the light at the patient’s eye and look for the red retinal reflex.
4. APPROACH & MAKE CONTACT Slowly follow the red reflex toward the patient and into the pupil. The eyecup should contact the patient’s brow. This contact is essential because it: 1. Establishes the proper viewing distance 2. Provides stabilization for the view 3. Creates a pivoting point for leverage in panning around the retina 4. Occludes ambient light
5. OPTIMIZE VIEW Adjust the focus (as necessary) to accommodate for your patient’s blur. Compress the eyecup about half its length to maximize the view.
6. WHAT YOU WILL SEE The entire optic disc and surrounding vessels should be visible. You should be realizing 5X the field-of-view you normally see with a standard ophthalmoscope in an undilated eye. This wide view makes it much easier to see important fundus features.
