II. Definition

  1. Palpebral Fissure
    1. Eliptical opening between the eye lids
    2. Normally 1 cm high by 3 cm wide in adults
  2. Downslanting Palpebral Fissure

    2. Downsloping lie of the eye opening with the medial canthus appearing higher than the lateral canthus
    3. With both eyes affected, a line drawn from each lateral canthus to medial canthus meeting at the nasal bridge, will form a "^" appearance
  3. Upslanting Palpebral Fissure

    2. Upsloping lie of the eye opening with the medial canthus appearing lower than the lateral canthus
    3. With both eyes affected, a line drawn from each lateral canthus to medial canthus meeting at the nasal bridge, will form a "V" appearance
  4. Short Palpebral Fissure

    2. Narrow eye openings with a decreased distance between the medial and lateral canthus
