What instrument is used to examine the interior portion of the eye?

• A. Stethoscope
• B. Ophthalmoscope
• C. Tonometer
• D. Retinoscope

Answer: (B)

The instrument used to examine the interior portion of the eye is the ophthalmoscope. This tool allows healthcare providers to inspect the retina and other internal eye structures by shining a light through the pupil. Through the combination of lenses and light, an ophthalmoscope enables a clear view of the optic nerve head, blood vessels, and the macula, which are crucial in diagnosing various ocular conditions such as diabetic retinopathy, glaucoma, and macular degeneration. In contrast, a stethoscope is primarily used for listening to heart and lung sounds, and a tonometer is specifically designed to measure intraocular pressure for glaucoma screening. A retinoscope, while used for refracting errors in vision and examining the back of the eye, does not provide as comprehensive a view of the interior structures as an ophthalmoscope does. Thus, the ophthalmoscope stands out as the correct choice for examining the interior portion of the eye.
