Total questions: 20
Worksheet time: 15mins
Which of the following best defines Dry Eye Disease (DED)?
A condition caused solely by reduced tear production
A disorder characterized by loss of tear film homeostasis and ocular symptoms
An infection of the ocular surface caused by bacteria
A disease only associated with aging
Which is NOT a key contributing factor to Dry Eye Disease (DED)?
Tear film instability
Hyperosmolarity
Inflammation
Increased tear reflex sensitivity
What is the estimated global prevalence range of Dry Eye Disease (DED)?
1–5%
5–50%
60–80%
Over 90%
Which of the following is an intrinsic risk factor for DED?
Prolonged digital screen use
Contact lens wear
Autoimmune diseases (e.g., Sjögren’s syndrome)
Air conditioning exposure
The main purpose of the TFOS DEWS III stepwise management approach is to:
Provide immediate surgical treatment for all DED patients
Offer a structured framework to escalate or de-escalate therapy based on severity
Focus only on pharmacological interventions
Eliminate the need for patient education
Which of the following is a recommended screening questionnaire for dry eye disease?
Patient Health Questionnaire
OSDI-6
Quality of Life Index
Visual Function Questionnaire
Which of the following is NOT a component of the differential diagnosis for dry eye disease?
Cataract surgery
Systemic diseases
Eyelid-related disorders
Corneal-related disorders
What is the recommended cut-off for tear meniscus height to indicate aqueous-deficient DED?
0.20 mm
0.30 mm
0.40 mm
0.10 mm
Which of the following is a recommended lifestyle modification in Step 1 management?
Daily systemic immunosuppressants
Avoiding screen breaks
Using humidifiers and reducing exposure to air conditioning
Scleral lens fitting
Lid hygiene in DED management primarily helps with:
Reducing corneal thinning
Improving meibomian gland function and lipid secretion
Increasing aqueous tear production
Strengthening corneal nerves
Punctal occlusion is introduced in TFOS DEWS III at which step?
Step 1
Step 2
Step 3
Step 4
Which event initiates the vicious cycle of Dry Eye Disease?
Ocular surface damage
Tear film instability
Goblet cell loss
Neurological dysfunction
What is the purpose of using validated questionnaires like OSDI in dry eye disease assessment?
To assess ocular surface disease symptoms
To determine tear break-up time
To evaluate corneal staining
To measure tear film height
What is considered an abnormal Tear Break-Up Time (TBUT)?
Between 3.1 and 6 seconds
Less than 10 seconds
Between 6.1 and 10 seconds
More than 10 seconds
What is the grading for Schirmer’s Test if the wetting is 5-10 mm?
Normal
Moderate
Mild
Severe
What is the significance of combining multiple tests in dry eye disease assessment?
To reduce the time of assessment
To eliminate the need for patient history
To confirm diagnosis and guide management
To focus on a single symptom
Which subtype of Dry Eye Disease (DED) is most commonly associated with Meibomian Gland Dysfunction (MGD)?
Aqueous-Deficient DED
Evaporative DED
Mixed-type DED
Post-surgical DED
Which test is considered the single best marker of Dry Eye Disease severity?
Schirmer’s test
Tear Break-Up Time (TBUT)
Tear Osmolarity
Ocular Surface Staining
Scleral contact lenses help DED patients by:
Acting as drug delivery systems for steroids
Increasing tear production via stimulation
Vaulting over the cornea to maintain hydration and protect the ocular surface
Reducing systemic inflammation
Which surgical intervention is included in Step 4 management for severe/refractory DED?
IPL therapy
Warm compresses
Tarsorrhaphy
Artificial tears
