  1. A patient reports haloes around lights after instillation of which class of drops?

    Answer: Mydriatic agents

    Mydriatic drops dilate the pupil, causing patients to notice haloes and glare around lights due to increased light entering through the peripheral lens.

  2. The Amsler grid is used to detect scotomas or distortion associated with disease of the:

    Answer: Macular area

    The Amsler grid detects distortion (metamorphopsia) or missing areas (scotomas) caused by macular conditions such as AMD.

  3. When instilling eye drops, the drop should be placed into the:

    Answer: Lower conjunctival fornix (cul-de-sac)

    Drops are instilled into the lower conjunctival fornix to minimize corneal contact, reduce reflex tearing, and allow proper absorption.

  4. Stereopsis testing with the Randot or TNO stereotest measures:

    Answer: Depth perception from binocular disparity

    Stereotests measure stereoacuity, the ability to perceive depth based on horizontal disparity between the images seen by each eye.

  5. Which solution is used to assess the cornea for abrasions or defects during a slit-lamp exam?

    Answer: Sodium fluorescein

    Sodium fluorescein stains areas where the corneal epithelium is disrupted and fluoresces green under cobalt blue light.

  6. When assessing extraocular muscle function, the cardinal positions of gaze test how many muscle pairs?

    Answer: 6

    The six cardinal positions of gaze (up-right, right, down-right, down-left, left, up-left) each isolate one primary-action muscle pair to test all six extraocular muscles.

  7. What is the purpose of the red reflex test performed with a direct ophthalmoscope?

    Answer: To screen for opacities in the ocular media

    A bright, symmetric red reflex indicates clear ocular media; a dull, absent, or asymmetric reflex suggests cataract, vitreous opacity, or retinoblastoma.
