Based on your performance on this Optometry Board Part 1 Practice Test, you’re not yet ready for the NBEO® Part 1.
Keep your head up! Also, don’t focus on your estimated score, they mean essentially nothing at the start. Rarely does anyone start these exams and score well immediately, if that was the case then they wouldn’t even need to practice! These are ‘practice’ tests, meaning you’re practicing to improve your skills. If you continue to work hard and study, read and understand the solutions, practice with “OptometryBoards.com” daily and give it your best effort, we promise your score will improve. Review and learn for now, and the scores will come.

Which of the Cranial Nerves is responsible for smiling?
A: CNVII – Facial Nerve provides motor innervation to muscles of facial expression. CNV – Trigeminal Nerve is separated into 3 branches. V1 is ophthalmic, V2 is maxillary, and V3 is mandibular. V1 and V2 provide sensory information while V3 provides motor input.

Which cranial nerves exit from the pons? (PICK 2)
C, D. CN III and IV exit from the midbrain. CN V, VI, VII, VII exit from the pons. The remaining cranial nerves exit from the medulla.

Which of the following pathways controls reflexive head movement in response to visual stimuli?
D. Trigeminothalamic pathway is responsible for reflexive head movement in response to stimuli. The medial lemniscus pathway carries information regarding touch, pressure, and vibration from the body. The spinothalamic pathway carries pain and temperature information from the body.

Internuclear ophthalmoplegia is characterized by:
A. An INO is caused by a lesion of the medial longitudinal fasciculus (MLF). The MLF is responsible for coordinating the conjugate movement of eyes with associated head/neck movements. A lesion to the MLF causes an INO – loss of ipsilateral adduction and a contralateral nystagmus.

Which structure within the diencephalon is responsible for regulating body temperature, hunger, and sleep?
D. The hypothalamus is responsible for regulating body temperature, hunger, and sleep. The epithalamus contains the pineal gland which regulates circadian rhythms. The thalamus acts as a relay station for sensory input to different cortical regions. The subthalamus and basal ganglia communicate to control muscle movement.

Which of the following statements regarding Optic Disc Drusen is INCORRECT?
D. Optic disc drusen are HYPERreflective on B scan ultrasound.
D. Optic disc drusen are HYPERreflective on B scan ultrasound.
Which of the following conditions is caused by incomplete closure of the fetal fissure?
B. An optic nerve coloboma is caused by the incomplete closure of the fetal fissure during development. The degree of visual impairment varies depending on severity and location. The defect is most commonly located in the inferior nasal region of the disc.

A patient presents with a congruous, homonymous hemianopia of the superior temporal visual field of both eyes. Where is the lesion most likely located?
C. The lesion is most likely located in the temporal lobe. To recall, think “pie in the sky”. If these findings were in the inferior field, it is suggestive of a lesion in the parietal lobe.
