Using a lens of +14D, magnification of fundus of an emmetropic eye in indirect ophthalmoscopy is:
**Core Concept**
The **magnification power** in indirect ophthalmoscopy depends on the **refractive power** of the lens used and the **refractive state** of the patient's eye. In an **emmetropic eye**, the magnification can be calculated based on the lens power.
**Why the Correct Answer is Right**
The formula to calculate magnification in indirect ophthalmoscopy is related to the lens power used. For a +14D lens, the magnification can be estimated, but the exact formula and typical values should be considered.
**Why Each Wrong Option is Incorrect**
**Option A:** This choice might be incorrect due to a miscalculation or misunderstanding of the formula.
**Option B:** Similarly, this option does not align with the expected magnification for the given lens power.
**Option D:** This choice is also incorrect as it does not match the calculated magnification for a +14D lens in an emmetropic eye.
**Clinical Pearl / High-Yield Fact**
In clinical practice, understanding the relationship between lens power and magnification in indirect ophthalmoscopy is crucial for **accurate fundus examination**.
**Correct Answer:** Correct Answer: B. 2.5 times
