1. The most common benign orbital tumor in adults is:

1. Dermoid cyst

2. Lacrimal gland adenoma

3. Neurofibroma

4. Cavernous (venous) hemangioma

2 / 10

2. Marcus Gunn jaw-winking syndrome is caused by:

1. Myasthenia gravis affecting the levator

2. Aberrant innervation of CN V to the levator (jaw movement causes lid retraction)

3. CN III palsy affecting levator

4. CN VII affecting the orbicularis

3 / 10

3. The most common cause of proptosis in adults is:

1. Orbital cellulitis

2. Orbital lymphoma

3. Thyroid eye disease (Graves' ophthalmopathy)

4. Cavernous hemangioma

4 / 10

4. Ptosis in myasthenia gravis is characterized by:

1. Fixed, non-variable, and unilateral always

2. Associated with pupil dilation

3. Variable (fatigable) ptosis, worsening with fatigue, positive edrophonium test

4. Associated with pain always

5. Orbital cellulitis is differentiated from preseptal (periorbital) cellulitis by:

1. Proptosis, restricted painful eye movements, reduced VA (postseptal involvement)

2. Eyelid swelling only without proptosis

3. Lower fever in orbital cellulitis

4. Presence of discharge only

6. Dacryocystitis is inflammation of:

1. The lacrimal sac (from nasolacrimal duct obstruction)

2. The lacrimal gland

3. The conjunctiva

4. The punctum only

7 / 10

7. Ptosis (drooping upper lid) with miosis and anhidrosis is a feature of:

1. CN III palsy

2. Horner syndrome (oculosympathetic pathway interruption)

3. Myasthenia gravis

4. CN VII palsy

8 / 10

8. Lagophthalmos (inability to close the eye completely) most commonly leads to:

1. Glaucoma from pressure

2. Cataract formation only

3. Exposure keratopathy (inferior corneal desiccation and ulceration)

4. Uveitis

9 / 10

9. Xanthelasma of the eyelids consists of:

1. Melanocyte proliferation

2. Papilloma virus lesions

3. Sebaceous gland cysts

4. Flat yellow lipid deposits (foam cells) in the eyelid dermis

10 / 10

10. Proptosis (exophthalmos) is defined as protrusion of the eyeball beyond:

1. 10 mm from the orbital rim

2. >21 mm axial protrusion or >2 mm asymmetry between eyes (Hertel measurement)

3. The eyelid margin

4. 15 mm from the orbital rim
