About This Quiz

A glaucoma is described as a group of eye conditions that damage the optic nerve, the health of which is important for good vision. The damage is often caused by abnormally high pressure in the eye. So, have you ever suffered from this condition? And if yes, can you pass our small test? Take this quiz and find out.

    What do adrenergic agonists do?

    • They provoke a release of of norepinephrine

    • They bring a lack in iron

    • They give marks on the skin

    • They create a local rash

    Correct Answer
    A. They provoke a release of of norepinephrine
    Explanation
    Adrenergic agonists are substances that stimulate the adrenergic receptors in the sympathetic nervous system. These receptors are activated by neurotransmitters like norepinephrine. Therefore, adrenergic agonists provoke a release of norepinephrine, which leads to various physiological responses such as increased heart rate, elevated blood pressure, and pupil dilation. This explanation aligns with the given correct answer, which states that adrenergic agonists provoke a release of norepinephrine.

    What is the best representative of parasympathomimetics?

    • Locarpine

    • Pilopine

    • Pilocarpine

    • Carpine

    Correct Answer
    A. Pilocarpine
    Explanation
    Pilocarpine is the best representative of parasympathomimetics because it is a direct-acting cholinergic agonist that stimulates the parasympathetic nervous system. It mimics the action of acetylcholine, the neurotransmitter responsible for activating the parasympathetic system. Pilocarpine is commonly used to treat conditions such as glaucoma, where it causes constriction of the pupil and reduces intraocular pressure by increasing the outflow of aqueous humor. Its parasympathomimetic effects also include increased salivation and sweating.

    What's an example of a beta-receptor antagonist on the market?

    • Detaxolol

    • Pretaxolol

    • Betaxolol

    • Betacolol

    Correct Answer
    A. Betaxolol
    Explanation
    Betaxolol is an example of a beta-receptor antagonist on the market. Beta-receptor antagonists, also known as beta-blockers, are drugs that block the action of adrenaline and noradrenaline on the beta receptors in the body. They are commonly used to treat conditions such as high blood pressure, angina, and heart rhythm disorders. Betaxolol specifically targets the beta-1 receptors, which are primarily found in the heart. By blocking these receptors, betaxolol helps to reduce heart rate and blood pressure, making it an effective medication for managing cardiovascular conditions.

    Why are carbonic anhydrase inhibitors important?

    • For cell repair

    • For eye muscle repair

    • For aqueous humor production

    • For tear production

    Correct Answer
    A. For aqueous humor production
    Explanation
    Carbonic anhydrase inhibitors are important for aqueous humor production. Aqueous humor is a clear fluid that fills the space in the front of the eye between the cornea and the lens. It helps maintain the shape of the eye and provides nutrients to the surrounding tissues. Carbonic anhydrase inhibitors work by reducing the production of aqueous humor, which can be beneficial in treating conditions such as glaucoma. By inhibiting the production of aqueous humor, these inhibitors help to lower intraocular pressure and prevent damage to the optic nerve.

    What are examples of medicines that raise ONH?

    • Brinzolamide and dorzolamide

    • Benzolamide

    • Dorsolamide

    • Endrolamine

    Correct Answer
    A. Brinzolamide and dorzolamide
    Explanation
    Brinzolamide and dorzolamide are examples of medicines that raise ONH. These medications belong to a class of drugs called carbonic anhydrase inhibitors, which are commonly used to lower intraocular pressure in patients with glaucoma. By inhibiting the activity of carbonic anhydrase, these drugs reduce the production of aqueous humor in the eye, thus helping to lower the pressure inside the eye. By raising ONH (optic nerve head), these medications can potentially improve the blood flow and protect the optic nerve from damage caused by increased intraocular pressure.

    What do treatment with parasympathomimetics involve?

    • Inducing contraction of smooth muscle cells in the ciliary body

    • Inducing contraction of old muscle cells in the ciliary body

    • Inducing contraction of long muscle cells in the ciliary body

    • Inducing contraction of hard muscle cells in the ciliary body

    Correct Answer
    A. Inducing contraction of smooth muscle cells in the ciliary body
    Explanation
    Treatment with parasympathomimetics involves inducing contraction of smooth muscle cells in the ciliary body. Parasympathomimetics are drugs that mimic the effects of the parasympathetic nervous system, which is responsible for promoting rest and digestion. The ciliary body is part of the eye and contains smooth muscle cells that control the shape of the lens for near and far vision. By inducing contraction of these smooth muscle cells, parasympathomimetics can help with conditions such as glaucoma or accommodative esotropia, where the lens needs to be adjusted for better vision.

    What's an example of topical therapy for glaucoma?

    • Adnergic agonistis

    • Alermagic agonistis

    • Adnenergic agonistis

    • Amenanergc agoritis

    Correct Answer
    A. Adnenergic agonistis
    Explanation
    Topical therapy for glaucoma refers to the use of eye drops or ointments directly applied to the eye to treat the condition. Adnenergic agonists are a type of medication used in topical therapy for glaucoma. They work by reducing the production of fluid in the eye, thereby lowering intraocular pressure and helping to manage the condition.

    Which treatment normalizes retinal blood flow?

    • Treatment with zolamide

    • Treatment with brinzolamide

    • Treatment with dorzolamide

    • Treatment with ice

    Correct Answer
    A. Treatment with dorzolamide
    Explanation
    Dorzolamide is a medication used to treat high pressure inside the eye due to glaucoma or other eye diseases. It belongs to a class of drugs called carbonic anhydrase inhibitors, which work by reducing the production of fluid in the eye. By reducing the fluid production, dorzolamide helps to lower the pressure inside the eye, which in turn normalizes retinal blood flow. Therefore, treatment with dorzolamide is the correct answer for normalizing retinal blood flow.

    What's the main problem with the inhibition of carbonic anhydrase?

    • It exerts potent vasodilator effects in the brain

    • It exerts potent vasodilator effects in the muscles

    • It exerts potent vasodilator effects in the eye

    • It exerts potent vasodilator effects in the heart

    Correct Answer
    A. It exerts potent vasodilator effects in the brain
    Explanation
    The main problem with the inhibition of carbonic anhydrase is that it exerts potent vasodilator effects in the brain. This means that it causes the blood vessels in the brain to widen, leading to increased blood flow. While this may seem beneficial, excessive vasodilation in the brain can result in increased intracranial pressure and potentially lead to conditions such as cerebral edema or hemorrhage. Therefore, inhibiting carbonic anhydrase can have detrimental effects on brain function and health.
