Introduction

Eye prominence plays a very important role on how your face is perceived, deep-set eyes are a male dimorphic trait, it has been hypothesized that deep-set eyes may be an adaptation for combat, hunting and male intrasexual selection, designed to protect the eyes from hits.




As you can see in the following image, towards the more masculine faces, the eyes become vertically narrower and more sunken:

Eye prominence is determined by the projection of the orbital rims in relation to the cornea.



The relationship of the globe to the orbital rims is a primary determinant of the appearance of the upper third of the face. Normal values are shown in the following image:



Classification of eye prominence

To measure the degree of eye prominence a hertel exophthalmometer is used, this device measures the position of the globe in relation to the lateral orbital rim.

The normal range of ocular protrusion as measured from the lateral orbital rim to the corneal apex is 14–21 mm in adults.

Depending on your exophthalmometry measurement, your eyes will be:

-Deep-set (<14mm)​
-Normal (15 to 17mm)​
-Moderately prominent (18 to 20mm)​
-Very prominent (>20mm)​


Orbital vector

Eye prominence can also be measured with the orbital vector, the orbital vector is determined by the linear relationship of the most anterior projection of the globe to the most anterior projection of the lower eyelid and the malar eminence.

According to this relationship, the orbital vector will be:

-Positive vector: The most anterior portion of the globe lies posterior to the lower eyelid margin, which lies posterior to the anterior malar eminence.​
-Neutral vector: The anterior globe, lower eyelid margin, and anterior malar eminence all lie in the same vertical plane.​
-Negative vector: The anterior globe lies anterior to the lower eyelid margin, which lies anterior to the malar eminence.​

Negative and positive orbital vectors:

The malar eminence is the most prominent point of the zygomatic bone (malar bone) and is always located anterior to the infraorbital rim, this is something that should be taken into account when augmenting the infraorbital rims with implants.

In most cases, a positive vector equates to a deep-set eye, while a negative vector results in a prominent eye.


Achieving deep-set eyes

To achieve deep-set eyes, you can either reduce the prominence of the globe or increase the projection of the orbital rims, in some cases both approaches may be necessary to achieve deep-set eyes.

The surgical procedure to reduce the promience of the eyeballs is called orbital decompression, it involves removing or thinning various safe orbital walls (and orbital fat), thereby expanding the eye socket, allowing the eyeball to settle back.

The best and safest first orbital wall to remove (or thin out) is the lateral orbital wall, followed by the medial wall, and last the orbital floor. More reduction with added risk is taken as more walls are decompressed. Incisions are hidden in the lateral upper eyelid crease (for lateral orbital decompression), caruncle or transcaruncular (for medial wall decompression) and lower eyelid conjunctiva (for orbital floor decompression).

To increase the projection of the orbital rims you can get orbital implants.

Also some osteotomies can augment the orbital rims:
LeFort 3 and Modified LeFort 3 advance the infraorbital and lateral orbital rims.
