    Rate this question:

  • 3. 

    Which of these statements is true?

    • The dysfunction or hypofunction of lacrimal glands and the consequent reduced volume of the aqueous layer of the tear film underlie ADDE

    • The dysfunction or hypofunction of Meibomian glands or reduced production of mucin proteins by conjunctival goblet cells increases the evaporation of tear fluid and results in EDED.

    • In more severe cases of Dry Eye, both the lacrimal and the meibomian glands may be impaired, resulting in a mixed (hybrid) phenotype characterized by signs of both ADDE and EDE.

    • All of them

    Correct Answer
    A. All of them
    Explanation
    All of the statements are true. The first statement explains that the dysfunction or hypofunction of lacrimal glands and the consequent reduced volume of the aqueous layer of the tear film are the underlying causes of ADDE (aqueous-deficient dry eye). The second statement states that dysfunction or hypofunction of Meibomian glands or reduced production of mucin proteins by conjunctival goblet cells lead to increased tear fluid evaporation and result in EDED (evaporative dry eye). The third statement explains that in more severe cases of Dry Eye, both lacrimal and Meibomian glands may be impaired, leading to a mixed phenotype characterized by signs of both ADDE and EDE. Therefore, all the statements are true.

    The non-contact meibography allows the observation of MG structure in silhouette through illumination of the eyelids from the skin side and is thereby able to detect morphological abnormalities.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The non-contact meibography technique enables the visualization of the structure of the meibomian glands (MG) by illuminating the eyelids from the skin side. This method allows for the detection of any abnormalities in the morphology of the MG. Therefore, the statement is true as it accurately describes the capabilities of non-contact meibography.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The Espansione ME-Check is a screening tool specifically designed for demodex. It is used to detect the presence of demodex mites on the skin. Therefore, the statement that the Espansione ME-Check allows demodex screening is true.

    ESW Vision TearCheck allows the evaluation of the staining of the cornea and the conjunctiva, of the stability of the tear film and of the anatomy of the meibomian glands.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    ESW Vision TearCheck is a tool that enables the assessment of various aspects related to the eyes, such as the staining of the cornea and conjunctiva, the stability of the tear film, and the anatomy of the meibomian glands. This indicates that the statement is accurate and the answer is true.

    • All of the above. 

    • None of the above

    Correct Answer
    A. All of the above. 
    Explanation
    The LipiFlow is composed of two primary components, an ocular disposable component (Activator) and a Handheld Control System. It also provides a heated surface with a nominal average temperature at the palpebral conjunctiva between 41°C and 43°C. Therefore, the correct answer is "All of the above."

    The Oculus Keratograph 5 M: 

    • Is a standard topographer present on the market from few years.

    • Is not focused on dry eye analysis.

    • Performs some examination for DED such as meibography, NIBUT, tear meniscus and redness detection.  

    • All of the above. 

    Correct Answer
    A. All of the above. 
    Explanation
    The Oculus Keratograph 5 M is a standard topographer that has been on the market for a few years. It is not only focused on dry eye analysis but also performs various examinations for dry eye disease (DED) such as meibography, non-invasive tear breakup time (NIBUT), tear meniscus evaluation, and redness detection. Therefore, the correct answer is "All of the above."

    The objective of the TBUT / NIBUT is to evaluate:

    • The tear film stability

    • The tear volume

    • The tear film composition

    • All of the above

    Correct Answer
    A. The tear film stability
    Explanation
    The TBUT/NIBUT test is used to evaluate the tear film stability. This test measures the time it takes for the tear film to break up or evaporate. By assessing tear film stability, eye care professionals can determine if there are any issues with tear production or tear film composition. This test helps in diagnosing conditions such as dry eye syndrome or meibomian gland dysfunction. Therefore, the correct answer is "The tear film stability."

    Rate this question:

  • 11. 

    The specific tests for the evaluation of the Meibomian glands are:

    • OSDI, SPEED, Schirmer, fluorescein staining and measurement of lower tear meniscus height with an OCT.

    • Osmolarity, TBUT, phenol read thread and rose Bengal staining

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "All of the above." This means that all of the tests mentioned in the options (OSDI, SPEED, Schirmer, fluorescein staining, measurement of lower tear meniscus height with an OCT, osmolarity, TBUT, phenol read thread, and rose Bengal staining) are specific tests used for the evaluation of the Meibomian glands. These tests assess various aspects of the Meibomian glands' function, tear production, tear quality, and ocular surface health.

    From a business standpoint, who would be potentially interested in our Dry Eye technology?

    • General ophthalmologist / Comprehensive ophthalmologist

    • Cataract and refractive surgeons 

    • Glaucoma specialists

    • Oculoplastic surgeons

    • All of them. 

    Correct Answer
    A. General ophthalmologist / Comprehensive ophthalmologist
    Explanation
    General ophthalmologists and comprehensive ophthalmologists would be potentially interested in our Dry Eye technology. This is because they are primary eye care providers who diagnose and treat a wide range of eye conditions, including dry eye. They are likely to encounter patients with dry eye symptoms and would benefit from having access to advanced technology for diagnosis and treatment. Other specialists like cataract and refractive surgeons, glaucoma specialists, and oculoplastic surgeons may also have an interest in our technology, but the primary target audience would be general and comprehensive ophthalmologists.

    1. The LipiView : accurately measures lipid layer thickness; 2) evaluates blink rate; 3) visualizes Meibomian gland structure; 4) Allows visualization of Demodex; 5) can detect MGD in its earliest stages.

    • 1, 2, 3

    • 1,2,3,4

    • 1,2,3,4,5

    • 1,2,3,5

    Correct Answer
    A. 1, 2, 3
    Explanation
    The LipiView is a device that has multiple functions. It accurately measures the thickness of the lipid layer, evaluates blink rate, and visualizes the structure of the Meibomian glands. Therefore, options 1, 2, and 3 are correct because they include these three functions. Option 4 is incorrect because it does not include the visualization of Meibomian gland structure. Option 5 is also incorrect because it does not include the accurate measurement of the lipid layer thickness.

  • 14. 

    The LipiScan accurately measures lipid layer thickness, evaluates blink rate and visualizes Meibomian gland structure.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the LipiScan does not evaluate blink rate. It accurately measures lipid layer thickness and visualizes Meibomian gland structure, but it does not have the capability to evaluate blink rate.
