  1. A patient with a right superior oblique palsy will most likely adopt which compensatory head posture?

    Answer: Head tilt to the left, chin down

    In right SO palsy, patients tilt their head to the left shoulder to reduce the hyperdeviation caused by the palsied muscle.

  2. The Parks three-step test is designed to isolate which type of muscle palsy?

    Answer: Cyclovertical muscle palsies

    The Parks three-step test uses three sequential observations to identify which of the eight cyclovertical muscles is paretic.

  3. Which of the following is the MOST appropriate initial management for a 6-month-old with infantile esotropia measuring 45 prism diopters?

    Answer: Full optical correction of any hyperopia and observation for 6 weeks

    Before surgery, any significant refractive error must be corrected first to rule out an accommodative component, then early surgery is planned.

  4. The Bagolini striated lens test is used to assess:

    Answer: Binocular function and suppression under natural viewing conditions

    Bagolini lenses have minimal optical interference and allow testing of binocular status under conditions close to everyday vision.

  5. A child consistently fails visual acuity screening in one eye despite having no refractive error or structural pathology. The next best step is:

    Answer: Repeat cycloplegic refraction and cover test evaluation

    Cycloplegic refraction may reveal latent hyperopia or anisometropia not apparent on manifest testing, and a cover test identifies strabismus.

  6. Which type of esotropia is characterized by a deviation that is controlled by accommodation and fully corrected with the hyperopic glasses prescription?

    Answer: Fully accommodative esotropia

    Fully accommodative esotropia is completely corrected by the full cycloplegic hyperopic prescription, eliminating the deviation without surgery.

  7. When grading the Worth 4-dot test, a patient who reports seeing five dots is demonstrating:

    Answer: Diplopia — no suppression present

    Seeing five dots means both eyes are open and the images are not fused, indicating uncrossed or crossed diplopia depending on dot positions.
