In the primary gaze position, the typical location of the upper eyelid relative to the limbus is approximately 2-3 mm below the limbus. This positioning is important for assessing eyelid function and aesthetics in both clinical and surgical contexts.

The limbus is the border between the cornea and the sclera, and understanding the normal anatomical relationships helps in diagnosing various conditions such as ptosis or eyelid retraction. The 2-3 mm spacing indicates a balance between eyelid coverage and exposure of the cornea, which is crucial for visual function and ocular health.

Variations outside of this range may suggest pathologies requiring further evaluation or intervention. Identifying this normal range allows healthcare providers to distinguish between normal eyelid positioning and potential abnormalities, aiding in appropriate treatment planning.
