Which statement about the PanOptic ophthalmoscope's field of view is true?

• A. It has the same field as the direct ophthalmoscope
• B. It provides a smaller field of view
• C. It requires the patient to be dilated
• D. It provides a 5x larger field of view than the standard direct ophthalmoscope

Answer: (D)

The PanOptic ophthalmoscope expands the view of the fundus by using a broader illumination cone and optics, giving a much wider glimpse of the retina than the classic direct ophthalmoscope. This wider view amounts to about a 25-degree field of view, roughly five times larger than the direct ophthalmoscope’s ~5-degree view. Clinically, that means you can see the optic nerve, vessels, and much more of the peripheral retina more readily, often without needing to dilate the pupil. So the statement about a fivefold larger field of view compared with the standard direct ophthalmoscope is the best choice. The other ideas aren’t accurate because the PanOptic does not give the same or a smaller field, and dilation is not strictly required to achieve its wide view.
