    Bitemporal hemianopia field defect is characteristic of?

    • Glaucoma

    • Optic neuritis

    • Pituitary tumour

    • Retinal detachment

    Correct Answer
    A. Pituitary tumour
    Explanation
    Pituitary tumors compress the optic chiasma and cause bitemporal hemianopia.

    Afferent pathway for pupillary light reflex is:

    • Trigeminal nerve

    • Optic nerve

    • Abducent nerve

    • Ciliary nerve

    Correct Answer
    A. Optic nerve
    Explanation
    The afferent pathway for the pupillary light reflex refers to the pathway through which sensory information from the eye is transmitted to the brain. In the case of the pupillary light reflex, the optic nerve is responsible for carrying this information. The optic nerve is specifically designed to transmit visual information from the retina to the brain, making it the correct answer for this question. The other options listed, such as the trigeminal nerve, abducent nerve, and ciliary nerve, are not involved in the afferent pathway for the pupillary light reflex.

    The average distance of the fovea from the temporal margin of the optic disc is:

    • 1 disc diameter

    • 2 disc diameter

    • 3 disc diameter

    • 4 disc diameter

    Correct Answer
    A. 2 disc diameter
    Explanation
    The correct answer is 2 disc diameter. The fovea is a small depression in the retina that is responsible for central vision. The optic disc is the point where the optic nerve exits the eye, and it is located on the nasal side of the retina. The average distance between the fovea and the temporal margin of the optic disc is 2 disc diameters. This means that the fovea is typically located about twice the distance of the diameter of the optic disc away from the temporal margin.

    Band shaped keratopathy is caused by:

    • Amyloid

    • Calcium

    • Monopolysaccharide

    • Lipid

    Correct Answer
    A. Calcium
    Explanation
    Band shaped keratopathy occurs due to the accumulation of calcium salts in a band pattern in the anterior corneal layers.

    The magnification obtained with a direct ophthalmoscope is:

    • 5 times

    • 10 times

    • 15 times

    • 20 times

    Correct Answer
    A. 15 times
    Explanation
    The magnification obtained with a direct ophthalmoscope is 15 times. This means that when using a direct ophthalmoscope, the image seen through the instrument appears 15 times larger than it actually is. This level of magnification allows for a detailed examination of the retina and other structures within the eye.

    Which of the following is not of prognostic significance in choroidal melanoma?

    • Presence of retinal detachment

    • Size of the tumor

    • Cytology of the tumor cells

    • Presence of extraocular extension

    Correct Answer
    A. Presence of retinal detachment
    Explanation
    Prognoistic factors in choroidal melanoma:
    Extent of metastatic disease
    Age
    Size of intraocular tumour
    Extent of extrascleral tumour extension
    Ciliary body involvement
    Histopathological and cytogenetic features

    Which of the following is NOT a common refractive error of the eye?

    • Myopia (nearsightedness)

    • Hyperopia (farsightedness) 

    • Astigmatism 

    • Glaucoma

    Correct Answer
    A. Glaucoma
    Explanation
    Glaucoma is a serious eye condition that damages the optic nerve, often due to increased pressure within the eye. It is not a refractive error, which refers to how the eye bends light to focus images on the retina. The other options are common refractive errors: myopia (difficulty seeing distant objects), hyperopia (difficulty seeing near objects), and astigmatism (blurred vision due to an irregularly shaped cornea).

  • 9. 

    The retina receives its blood supply from all, except:

    • Posterior ciliary artery

    • Central retinal artery

    • Retinal arteries

    • Plexus of Zinn and Haller arteries

    Correct Answer
    A. Posterior ciliary artery
    Explanation
    The retina receives its blood supply from the central retinal artery, retinal arteries, and the plexus of Zinn and Haller arteries. The posterior ciliary artery does not supply blood to the retina.
