    What is the magnification of a direct ophthalmoscope? - ProProfs

    What is the magnification of a direct ophthalmoscope?

    • 10

    • 20

    • 15

    • 17

    Correct Answer
    A. 15
    Explanation
    The magnification of a direct ophthalmoscope is 15. This means that when looking through the ophthalmoscope, the image seen appears 15 times larger than it would to the naked eye. This magnification is useful for examining the structures of the eye in detail, such as the retina and optic nerve.

    A direct ophthalmoscope inspects the eye  - ProProfs

    A direct ophthalmoscope inspects the eye 

    • Aqueous humour

    • Retina

    • Fundus

    • Fovea

    Correct Answer
    A. Fundus
    Explanation
    A direct ophthalmoscope is a handheld instrument used by healthcare professionals to examine the inside of the eye. It allows them to visualize the structures at the back of the eye, including the retina, optic disc, and blood vessels. The term "fundus" refers to the posterior part of the eye, which includes the retina and the optic disc. Therefore, the correct answer is "fundus."

    All these changes can be detected using a direct ophthalmoscope except  - ProProfs

    All these changes can be detected using a direct ophthalmoscope except 

    • Changes in color of fundus

    • Changes in shape of the retinal blood vessels

    • Changes in the macula lutea

    • Changes in the vitreous humor

    Correct Answer
    A. Changes in the vitreous humor
    Explanation
    A direct ophthalmoscope is a medical instrument used to examine the interior structures of the eye, including the retina, blood vessels, and macula lutea. It is capable of detecting changes in color of the fundus, changes in the shape of the retinal blood vessels, and changes in the macula lutea. However, it is not able to detect changes in the vitreous humor, which is the gel-like substance that fills the space between the lens and the retina. Therefore, changes in the vitreous humor cannot be detected using a direct ophthalmoscope.

    Which of these is not a feature produced by indirect ophthalmoscope? - ProProfs

    Which of these is not a feature produced by indirect ophthalmoscope?

    • Upright

    • ​​​​​​Unreversed 

    • Indirect

    • Virtual

    Correct Answer
    A. Virtual
    Explanation
    The indirect ophthalmoscope produces an upright, unreversed, and indirect image of the retina. However, it does not produce a virtual image. A virtual image is an optical image that is formed by the apparent intersection of rays of light, but cannot be projected onto a screen. The indirect ophthalmoscope instead produces a real image, which can be projected onto a screen or viewed directly through the device.

    Which of these is not a feature of images produced by indirect ophthalmoscope? - ProProfs

    Which of these is not a feature of images produced by indirect ophthalmoscope?

    • Inverted

    • Reversed

    • Direct

    • Virtual

    Correct Answer
    A. Virtual
    Explanation
    The indirect ophthalmoscope is a device used to examine the retina and other structures of the eye. It produces an inverted and reversed image of the retina, meaning that the image appears upside-down and flipped horizontally. This is a characteristic feature of images produced by the indirect ophthalmoscope. However, the images produced are not virtual, meaning they are not created by a computer or simulated. Therefore, virtual is not a feature of images produced by the indirect ophthalmoscope.

    The ophthalmoscope can be focused using the - ProProfs

    The ophthalmoscope can be focused using the

    • Ophthalmoscope wheel 

    • Ophthalmoscope knob

    • Focusing wheel

    • Focusing knob

    Correct Answer
    A. Focusing wheel
    Explanation
    The correct answer is the focusing wheel. The ophthalmoscope can be focused using a wheel that allows for adjustments to be made to the focus of the instrument. This wheel is specifically designed for focusing purposes and enables the user to achieve a clear and sharp image of the patient's eye. The other options mentioned, such as the ophthalmoscope knob or focusing knob, do not accurately describe the specific mechanism used for focusing the ophthalmoscope.

    The first opthalmoscope was invented by  - ProProfs

    The first opthalmoscope was invented by 

    • Adolf Shell

    • Robbin Lord

    • Adolf Coccius

    • Richard Euler

    Correct Answer
    A. Adolf Coccius
    Explanation
    Adolf Coccius is the correct answer because he was the inventor of the first ophthalmoscope. He developed this device in 1851, which allowed physicians to examine the interior structures of the eye. This invention revolutionized the field of ophthalmology by enabling doctors to diagnose various eye conditions more accurately. Adolf Shell, Robbin Lord, and Richard Euler are not associated with the invention of the ophthalmoscope.

    Which of the following is not part of the Juler electric ophthalmoscope? - ProProfs

    Which of the following is not part of the Juler electric ophthalmoscope?

    • Driving wheel

    • Lamp housing

    • Adjustment knob

    • Bulb

    Correct Answer
    A. Adjustment knob
    Explanation
    The adjustment knob is not part of the Juler electric ophthalmoscope. This is because the adjustment knob is used to adjust the focus or intensity of the light, which is not a feature typically found in an electric ophthalmoscope. The driving wheel is used to control the movement of the ophthalmoscope, the lamp housing houses the bulb, and the bulb provides the light source for the ophthalmoscope.
