    TRUE OR FALSE??? During the cover-uncover test, the eye with the defect will shift positions when it is uncovered

    • True

    • False

    Correct Answer
    A. True
    Explanation
    During the cover-uncover test, the eye with the defect will shift positions when it is uncovered. This is because the test is used to detect a misalignment in the eyes, such as strabismus. When one eye is covered, the brain compensates for the misalignment by adjusting the position of the uncovered eye. As a result, when the covered eye is uncovered, the brain readjusts the position of the eyes, causing the eye with the defect to shift positions. Therefore, the statement is true.

    Correct Answer
    A. Rods
    Explanation
    Rods are the photo sensitive cells that are utilized in low levels of light and are responsible for night vision and peripheral vision. Unlike cones, which are responsible for color vision and work best in bright light, rods are more sensitive to light and allow us to see in dimly lit environments. They are concentrated in the outer regions of the retina and are responsible for our ability to see objects in our peripheral vision. Rhodopsin, a pigment found in rods, plays a crucial role in their function by absorbing light and initiating the process of visual perception.

    Cones are the photo sensitive cells that permit better visual acuity and color vision. Unlike rods, which are more sensitive to light and are responsible for vision in low light conditions, cones are responsible for color vision and high visual acuity. They are concentrated in the central part of the retina, called the fovea, which is responsible for sharp and detailed vision. Cones are also responsible for distinguishing different colors and are more active in well-lit conditions.

    Rate this question:

  • 20. 

    TRUE OR FALSE?? During accommodation, the pupils constrict as the curvature of the lens is changed to adjust from a distant object to a near object.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    During accommodation, the ciliary muscles contract, causing the curvature of the lens to change. This adjustment allows the eyes to focus on near objects. As a result of this change in lens shape, the pupils constrict to control the amount of light entering the eye and ensure a clear image is formed on the retina. Therefore, the statement "During accommodation, the pupils constrict as the curvature of the lens is changed to adjust from a distant object to a near object" is true.

    Correct Answer
    A. Dacryoadenitis
    Explanation
    Dacryoadenitis is the correct answer because it refers to the acute inflammation of the lacrimal gland. The lacrimal gland is responsible for producing tears, and inflammation of this gland can cause symptoms such as pain, redness, and swelling around the eye. Dacryocystitis refers to inflammation of the tear duct, blepharitis refers to inflammation of the eyelid, hordeolum refers to a stye or infection of the eyelash follicle, and chalazion refers to a blocked oil gland in the eyelid.

    TRUE OR FALSE?? Chronic dacryoadenitis is seen with lymphoma, leukemia, tuberculosis, and sarcoidosis.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Chronic dacryoadenitis is inflammation of the lacrimal gland, which is responsible for producing tears. It can be seen in various conditions including lymphoma, leukemia, tuberculosis, and sarcoidosis. These conditions can cause chronic inflammation and enlargement of the lacrimal gland, leading to symptoms such as pain, swelling, and tearing. Therefore, the statement "Chronic dacryoadenitis is seen with lymphoma, leukemia, tuberculosis, and sarcoidosis" is true.

    In ______ dacryocystitis, the usual infectious organisms are staph aureus and beta-hemolytic stretococci. In _______ dacryocystitis, the usual infectious organisms are staph epidermidis, anaerobis stretococci, and candida albicans.

    • Chronic, acute

    • Acute, chronic

    • Anterior, posterior

    • Posterior, anterior

    Correct Answer
    A. Acute, chronic
    Explanation
    In acute dacryocystitis, the usual infectious organisms are staph aureus and beta-hemolytic streptococci. This is because acute dacryocystitis is typically caused by a sudden infection of the lacrimal sac, which is commonly associated with these bacteria. On the other hand, chronic dacryocystitis is characterized by a long-standing inflammation and obstruction of the lacrimal sac, leading to a different set of infectious organisms. Staph epidermidis, anaerobic streptococci, and candida albicans are commonly found in chronic dacryocystitis due to the chronic nature of the condition and the presence of biofilms.

    Where in the eye should you examine for hyphema (blood)?

    • Retina

    • Aqueous humor

    • Vitreous body

    • Posterior chamber

    • Anterior chamber

    Correct Answer
    A. Anterior chamber
    Explanation
    The anterior chamber is the correct answer because it is the front part of the eye between the cornea and the iris. It is filled with a clear fluid called aqueous humor. When there is bleeding in the eye, known as hyphema, it typically occurs in the anterior chamber. Therefore, to examine for hyphema, one should look in the anterior chamber of the eye.

    If both you and the patient have no refractive errors, the retina should be in focus at how many diopters?

    • 0

    • 1

    • 2

    • 4

    • 5

    Correct Answer
    A. 0
    Explanation
    If both the person and the patient have no refractive errors, it means that their eyes can focus light perfectly onto the retina without the need for any corrective lenses. In this case, the retina should be in focus at 0 diopters, as no additional correction is required.

    TRUE OR FALSE?? Dacryocystitis is usually bilateral.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Dacryocystitis is an inflammation or infection of the tear sac, which is located in the corner of the eye near the nose. It is commonly caused by a blockage in the tear duct. While it can affect both eyes, it is not usually bilateral. Dacryocystitis typically affects only one eye at a time, causing symptoms such as swelling, redness, pain, and discharge.

    Itching is characteristically associated with...

    • Trauma, infection, inflammation, or sudden increase in intraocular pressure.

    • Corneal or conjunctival foreign bodies, disturbances of the corneal epithelium, and rubbing of the eyelashes against the cornea (trichiasis).

    • Corneal inflammation, iritis, or fever associated with various systemic infections.

    • Allergic eye disease

    • Hyperemia of the conjunctival, episcleral, or ciliary vessels; erythema of the eyelids, or subconjunctival hemorrhage.

    Correct Answer
    A. Allergic eye disease
    Explanation
    Itching is characteristically associated with allergic eye disease. Allergic eye disease refers to conditions such as allergic conjunctivitis, which can cause itching, redness, and swelling of the eyes. It is often triggered by allergens such as pollen, pet dander, or dust mites. This immune response causes the release of histamine, leading to itching and other symptoms. Other options mentioned in the question, such as trauma, infection, inflammation, or increase in intraocular pressure, may cause different symptoms but are not specifically associated with itching.
