**Question:** Indirect ophthalmoscopy is done for –

A. Examining the fundus
B. Detecting intraocular foreign bodies
C. Assessing the intraocular pressure
D. Examining the anterior segment of the eye

**Core Concept:** Indirect ophthalmoscopy is a clinical examination technique used in ophthalmology to visualize the fundus, which is the back part of the eye. It allows doctors to assess the health of the retina, optic nerve, and other structures of the posterior segment.

**Why the Correct Answer is Right:** Indirect ophthalmoscopy involves the use of an ophthalmoscope, which is a handheld device with a light source and a mirror. The mirror reflects light into the eye, allowing the ophthalmologist to observe the fundus. This technique is chosen over direct ophthalmoscopy because it provides a larger field of view and better visualization of the posterior segment due to reduced reflexes and glare.

**Why Each Wrong Option is Incorrect:**

A. Examining the anterior segment of the eye (direct ophthalmoscopy is used for this purpose)
B. Detecting intraocular foreign bodies (ultrasonography or other imaging techniques are more appropriate for this purpose)
C. Assessing the intraocular pressure (tonometry is the appropriate tool for assessing intraocular pressure)

**Clinical Pearl:** Indirect ophthalmoscopy plays a crucial role in detecting various eye diseases and conditions, such as retinal detachment, diabetic retinopathy, and retinal hemorrhages. A thorough understanding of this technique is essential for accurate diagnosis and management of ocular diseases.

**Correct Answer:** A. Examining the fundus
