The palpebral fissure is the elliptic space between the medial and lateral canthi of the two open eyelids. In simple terms, it is the opening between the eyelids. In adult humans, this measures about 10 mm vertically and 30 mm horizontally.

2019年7月11日 · The palpebral fissure refers to the normal exposed area between upper and lower eyelids. The palpebral fissure vertical height (PFH) is measured between the margin of the lower eyelid to the margin of the upper eyelid.

2025年1月22日 · The palpebral fissure refers to the elliptical opening between the upper and lower eyelids. It is the visible space of the eye that you see when the eyes are open. The shape and size of the palpebral fissure can vary between individuals due to genetic, developmental, or medical factors.

The palpebral fissure is the elliptic space between the medial and lateral canthi of the two open lids. In adults, this measures about 10mm vertically and 30 mm horizontally.

Palpebral fissures are described as up-slanted when the outer canthus is positioned higher than usual, down-slanted when the outer canthus is lower than usual. Up-slanted palpebral fissures may be associated with microcephaly.

2023年10月30日 · The eye has two palpebral fissures, horizontal and vertical, which stand for the normal exposed area between the superior and inferior eyelids. The elliptical opening between them is known as the palpebral aperture.

Subjective: A shape created by an acute downward arching of the upper eyelid and upward arching of the lower eyelid, toward the medial canthus, which gives the outline of the palpebral fissures the configuration of an almond; thus, the maximum distance between the fissures is offset from, and medial to, the center point

The palpebral fissure is the space in the corner of the eye between the eyelids, in the area where the lower and upper lids meet. There are some normal variations in size and shape of this anatomical feature that can occur between populations.

The meaning of PALPEBRAL FISSURE is the space between the margins of the eyelids —called also rima palpebrarum.

2019年7月11日 · The palpebral fissure refers to the normal exposed area between upper and lower eyelids. It is measured between the margin of the lower eyelid to the margin of the upper eyelid. The normal palpebral fissure height (sometimes abbreviated PFH) is 8-11 mm. This is a key measurement that you need when assessing for ptosis (droopy eyelid).
