Which modality provides a larger field of view and a real inverted image?

• A. BIO
• B. Direct Ophthalmoscopy
• C. Both
• D. Neither

Answer: (A)

Binocular Indirect Ophthalmoscopy uses a condensing lens to create a real, magnified image of the retina that you view with indirect optics. This arrangement gives a much larger field of view than direct methods, and the image is inverted (upside down) relative to the retina. Direct ophthalmoscopy, on the other hand, produces a smaller, erect (not inverted) image that is mainly a virtual view, so it doesn’t provide the wide view or the real inverted image seen with BIO. So the modality that offers both a larger field of view and a real inverted image is Binocular Indirect Ophthalmoscopy.
