The following conditions can cause anisocoria except
a. Herniation
b. CN II paralysis
c. NOTA
d. Horner syndrome

b. CN II paralysis

Anisocoria refers to a condition where the two pupils of the eyes are of unequal size. The optic nerve (CN II) is responsible for vision, not pupil size. Pupil size and reaction are mainly governed by the sympathetic and parasympathetic pathways involving CN III (oculomotor nerve). Thus, CN II paralysis wouldn’t typically cause anisocoria. The other options can be associated with anisocoria. (NOTA usually means “None Of The Above,” and if “Homer syndrome” is a typo and you meant “Horner’s syndrome,” then Horner’s syndrome can indeed cause anisocoria.)

40 year old female with 2 month history of headaches and blurring of vision. On fundoscopy, the following is noted. What is your most likely diagnosis
a. Central retinal artery occlusion
b. Optic neuritis
c. Retinal detachment
d. Papilledema

d. Papilledema

Rationale:
Papilledema is swelling of the optic disc due to increased intracranial pressure. The clinical symptoms of headaches and blurred vision combined with fundoscopic findings of swollen optic disc would be most consistent with papilledema. The other options provided have distinct clinical and fundoscopic presentations different from the scenario described.

A 24 y/o female consulted for right eye proptosis. She was involved in a vehicular crash 2 weeks prior. On examination, there was noted of proptosis and chemosis of the left eye, with limited extraocular movements. There was also note of bruit on auscultation. What will be the definitive management for the patient?
a. Observation
b. Steroid therapy
c. Endovascular technique/intervention
d. Antibiotic treatment

c. Endovascular technique/intervention

Rationale:
The presentation described suggests a carotid-cavernous fistula (CCF). CCFs can occur traumatically, as might be the case following a vehicular crash. Symptoms of a CCF include proptosis (bulging of the eye), chemosis (swelling of the conjunctiva), decreased eye movement, and a bruit that can be heard over the eye or orbit. The definitive management for a traumatic CCF is typically endovascular intervention to close off the abnormal connection between the carotid artery and the cavernous sinus.

Which fibers of the optic nerve cross at the optic chiasm?
a. Nasal fibers of the optic nerve
b. There is no crossing of fibers occurring at the level of the optic chiasm
c. Both nasal and temporal fibers
d. Temporal fibers of the optic nerve

a. Nasal fibers of the optic nerve

Rationale:
At the optic chiasm, the nasal (or medial) retinal fibers from each eye cross to the opposite side. These fibers carry visual information from the temporal (or lateral) visual fields of each eye. In contrast, the temporal (or lateral) retinal fibers do not cross and continue on the same side. This arrangement allows for binocular vision and depth perception.

A 50 year old female consults for blurring of vision. Visual acuity test using Snellen chart revealed 20/40 on the right eye which improved upon pinhole test. What is the most likely diagnosis?
a. Intracranial tumor
b. Error of refraction
c. Optic neuritis
d. Presbyopia

Answer: b. Error of refraction

Rationale:
When visual acuity improves with the use of a pinhole test, it typically indicates a refractive error. The pinhole acts as a tool to eliminate peripheral rays of light, allowing only the central rays to enter the eye, which helps correct for refractive errors like myopia, hyperopia, or astigmatism. The fact that the vision improved upon pinhole testing suggests that the blurring is due to a refractive error rather than a pathological process affecting the retina or optic nerve.

While palpating both sides of the neck of a 60 year old female, the patient fainted. What possibly happened? a. The patient was probably hungry b. The examiner palpated both sides of the neck at the same time, evoking cardiac syncope followed by orthostatic hypotension c. The examiner palpated both sides of the neck at the same time, evoking a carotid body reflex with vasovagal syncope d. The examiner palpated both sides of the neck at the same time, evoking a carotid sinus reflex with vasovagal syncope.

d. The examiner palpated both sides of the neck at the same time, evoking a carotid sinus reflex with vasovagal syncope. The carotid sinus is a baroreceptor located in the carotid bifurcation. When it's excessively stimulated, it can cause a reflex drop in heart rate and blood pressure, leading to a vasovagal syncope. This is why clinicians are cautioned not to massage or palpate both carotid sinuses at the same time.

46. Generalized Lymphadenopathy is suggestive of multiple causes except for: a. LEUKEMIA b. GOITER с. LYMPHOMA d. HIV

b. GOITER

47. An ominous high-pitched musical sound from sever subglottic or tracheal obstruction: a. Hoarseness b. Stertor c. Wheezing d. Stridor

d. Stridor Rationale for the choices: a. Hoarseness: Refers to a change in the pitch or quality of the voice. It results from disorders of the vocal cords, but not necessarily from an obstruction. b. Stertor: Refers to noisy breathing that occurs during inhalation. It’s often caused by an obstruction in the nasal passage or pharynx and produces a snoring-like sound. c. Wheezing: A high-pitched continuous sound, often heard on exhalation, due to narrowing of the lower airways, commonly seen in conditions like asthma. d. Stridor: A high-pitched, musical sound caused by an obstruction in the upper airway, most often heard during inhalation. It’s a sign of a potential emergency, especially if it occurs suddenly, as it indicates significant narrowing or obstruction in the trachea or larynx and can lead to complete airway obstruction.

48. The Stensen’s duct opens in which area? a. In the buccal mucosa near the second lower premolar b. In the buccal mucosa near the upper second molar c. In the buccal mucosa near the upper second premolar d. In the buccal mucosa near the lower second molar

c. In the buccal mucosa near the upper second premolar Rationale: The Stensen’s duct is the main excretory duct of the parotid gland. It traverses over the masseter muscle, turns medially at the anterior border of the masseter, and penetrates the buccal fat. It then opens into the oral cavity in the buccal mucosa opposite the upper second premolar. The location of its opening is important clinically, especially in cases of sialolithiasis (stones in salivary duct) or infections. The other options (a, b, d) incorrectly identify the location of the Stensen's duct opening in relation to the dental anatomy.

49. A pulsating neck mass is suggestive of what condition a. Goiter b. Malignancy c. Vascular mass d. Infected lymph node

6. A 45 year old male with a one (1)-year history of ear fullness only on the right ear, occasional blood streaked nasal discharge and a right lateral neck mass should make you suspicious of which condition? A. Adenoid hypertrophy B. Nasal polyp C. Nasopharyngeal carcinoma D. Recurrent tonsillitis

C. Nasopharyngeal carcinoma Rationale: The presentation described – right ear fullness, occasional blood-streaked nasal discharge, and a right lateral neck mass in a 45-year-old male – is highly suggestive of nasopharyngeal carcinoma (NPC). NPC is known to present with these types of symptoms due to the tumor's location in the nasopharynx, which can block the Eustachian tube leading to ear symptoms, cause epistaxis or bloody discharge, and metastasize to cervical lymph nodes causing a neck mass. A. Adenoid hypertrophy is more common in children and would not typically present with bloody nasal discharge or a neck mass. B. Nasal polyps can cause nasal obstruction but are not typically associated with ear fullness, bloody discharge, or neck masses. D. Recurrent tonsillitis would primarily present with sore throat and may lead to swollen tonsils, but it wouldn't typically cause ear fullness, bloody nasal discharge, or a neck mass.

38. Which of the following instructions/statements is/are incorrect during finger wiggle test/confrontation test? A. None of the above B. “Look straight into my eye” C. "Look at my fingers at the periphery" D. “Cover one of your eyes”

C. “Look at my fingers at the periphery” During the confrontation test, the patient should be instructed to focus on the examiner's eyes (or a fixed point on the examiner's face) while the examiner wiggles their fingers or uses some form of stimulus in the patient's peripheral vision. Asking the patient to look at the fingers in the periphery would defeat the purpose of testing peripheral vision.

39. When the right eye looks down and out, which of the following extraocular muscles are tested? A. Inferior rectus B. Superior oblique C. Inferior oblique D. Superior rectus

D. Superior rectus

40. Which of the following will present with masked like fascie, decreased blinking and a characteristic stare? A. Hyperthyroidism B. Myxedema C. Parkinson's disease D. Nephrotic syndrome

C. Parkinson's disease

41. Which of the following findings during ophthalmoscope exam is indicative of increased intracranial pressure? A. Exudates B. Neovascularization C. Papilledema D. Optic atrophy

C. Papilledema

A. Left homonymous hemianopia B. Left homonymous superior quadrantanopia C. Right homonymous superior quadrantanopia D. Left homonymous inferior quandrantanopia

B. Left homonymous superior quadrantanopia

A. Right optic nerve B. Right optic tract C. Optic chiasm D. Left geniculocalcarine radiation

B. Right optic tract (Left Homonymous Hemianopsia)

44. Which of the following is consistent with Horner’s syndrome? A. Mydriasis B. Small irregular pupils that do not accommodate C. Impaired extraocular muscle movement D. Anhydrosis

D. Anhydrosis Horner's syndrome is characterized by miosis (constricted pupil), ptosis (drooping of the upper eyelid), and anhidrosis (lack of sweating) on the affected side of the face.

45. A 50 year old female presents with sudden severe headache and diplopia. On primary gaze, you noted that the right eye is down and out. Which of the following is most likely affected? A. Oculomotor nerve B. Lateral rectus C. Abducens nerve D. Trochlear nerve

A. Oculomotor nerve The classic presentation of an "eye that is down and out" is indicative of a dysfunction of the oculomotor nerve (cranial nerve III). The oculomotor nerve innervates the majority of the extraocular muscles: superior rectus, inferior rectus, medial rectus, and inferior oblique. Additionally, it provides parasympathetic fibers to the pupil. When there's a dysfunction of the oculomotor nerve, the unopposed actions of the lateral rectus (abduction or "out") and superior oblique (depression or "down") muscles lead to the eye being positioned "down and out." Given the provided options, the most likely affected is: A. Oculomotor nerve

46. Normal features of the optic disk, except: A. White optic disc B. Blurred nasal portion C. Yellowish-white central physiologic cup D. Physiologic cup horizontal diameter is less than half of the disc diameter

A. White optic disc

47 Which fibers of the optic nerve cross at the optic chiasm? A. There is no crossing of fibers occurring at the level of the optic chiasm B. Both nasal and temporal fibers C. Temporal fibers of the optic nerve D. Nasal fibers of the optic nerve

D. Nasal fibers of the optic nerve

48. A 50 year old female consults for blurring of vision. Visual acuity test using Snellen chart revealed 20/40 on the right eye which improved upon pinhole test. What is the most likely diagnosis? A. Presbyopia B. Optic neuritis C. Intracranial tumor D. Error of refraction

D. Error of refraction

49. How many cardinal directions of gaze are tested during EOM testing? A. five B. Seven C. Six D. four

C. Six

50. The distance by which a patient should hold the Jaeger chart during visual acuity examination A. 2 feet B. 20 inches C. 20 feet D. 14 inches

D. 14 inches
