Drooping corner of the eye
back to main page
A drooping corner of the eye is a colloquial term for a situation in which the lateral canthus is positioned lower than the medial canthus or gives such an impression due to the drooping of the lateral part of the eyebrow, eyelid laxity, or excess skin. In aesthetic anatomy, the position of the corners is described by the angle of inclination of the palpebral fissure, known as the canthal tilt. A negative tilt can be a congenital trait or a change that intensifies with age. It is not a disease in itself; however, asymmetry that appears suddenly, incomplete eye closure, tearing, double vision, or drooping of the eyelid require ophthalmic or neurological diagnostics. The method of correction depends on whether the problem concerns the actual position of the lateral canthus, lower eyelid stability, eyebrow position, tissue volume, or solely skin quality.
Downturned corner of the eye - what it looks like
A proper assessment should not be based solely on the subjective impression of a “sad look”. Several distinct anatomical phenomena must be distinguished:
- negative canthal tilt, when the lateral canthus lies lower than the medial canthus;
- horizontal alignment of the palpebral fissure, which is a normal anatomical variant;
- drooping of the lateral part of the eyebrow, causing a skin overhang over the outer part of the upper eyelid;
- lower eyelid laxity, sometimes with scleral show below the iris, rounding of the lateral canthus, or pulling away of the eyelid margin;
- dermatochalasis, which is an excess of lax eyelid skin;
- upper eyelid ptosis, related to an abnormal position of its margin rather than the corner itself.
The examination evaluates facial symmetry, the height of both eye corners, the shape of the palpebral fissures, eyebrow position, lower eyelid tone, scleral exposure, and the so-called orbital vector, which is the relationship of the eyeball to the bony support of the midface. Assessing facial expressions is also important, as drooping may be more noticeable at rest or while smiling.
A unilateral feature present for years most often results from natural asymmetry. A sudden change, especially accompanied by facial muscle weakness, visual disturbances, eye pain, unequal pupil size, or a severe headache, requires urgent medical consultation.
Drooping corner of the eye - when is it a congenital trait
The congenital position of the lateral canthus is a result of the individual anatomy of the bony orbit, palpebral ligaments, and soft tissues. Of particular importance are the height and shape of the lateral orbital rim, the attachment site of the lateral canthal tendon, the length of the palpebral fissure, lower eyelid tension, and zygomatic bone projection. These features are genetically determined and vary individually, by sex, and across populations.
Congenital negative palpebral tilt:
- is usually bilateral, although it may occur asymmetrically;
- remains relatively stable after the completion of craniofacial growth;
- does not cause visual impairment or eyelid dysfunction;
- may coexist with a horizontally positioned eyebrow, weaker lower eyelid support, or a more prominent eyeball;
- does not require treatment if it represents merely a variant of appearance.
In children, a specific configuration of the palpebral fissures may less frequently be part of a developmental defect or genetic syndrome. In such cases, what matters is not the shape of the eyes itself, but the coexistence of other abnormalities, such as developmental disorders, abnormal eyelid structure, visual field limitation, or marked craniofacial asymmetry.
Congenital anatomy should not be confused with ptosis, facial nerve palsy, or acquired laxity of the canthal tendon. Reviewing photographs from earlier years often helps determine whether the feature was present from childhood or only appeared during the aging process.
Drooping corner of the eye - why it deepens with age
Aging of the periorbital area is a three-dimensional process. It involves bones, ligaments, muscles, fat compartments, and skin. Therefore, not only the surface of the eyelids changes, but also their support.
The primary contributors to the worsening appearance of a drooping corner of the eye are:
- orbital bone remodeling, including the widening of its aperture and the retrusion of parts of the bony rim;
- laxity of supporting structures, especially the lateral canthal ligament and lateral eyelid-orbital attachments;
- drooping of the lateral part of the brow, which has weaker frontalis muscle support than the medial part;
- displacement and atrophy of fat compartments, altering the support of the temple, brow, and lower eyelid;
- decrease in collagen and elastin, leading to thinning and laxity of the skin;
- photoaging, exacerbating the degradation of the extracellular matrix;
- repetitive contractions of the orbicularis oculi muscle, setting lateral wrinkles and affecting the position of the brow tail.
Apparent drooping may result mainly from skin overhang over the lateral part of the eyelid, even though the actual position of the canthal ligament remains correct. In other individuals, lower eyelid laxity or temporozygomatic volume loss predominates.
The process does not occur identically in everyone. Studies show that the middle part of the brow may remain stable with age, or even elevate as a result of compensatory activity of the frontalis muscle, while its lateral part droops more frequently. Therefore, qualification for the procedure must encompass the entire periorbital region, not just the corner of the eye.
Drooping corner of the eye - how to lift it
The method is selected according to the structure responsible for the change. Treatments that improve skin quality can create the effect of a more open look, but do not directly alter the attachment of the lateral canthal tendon.
Ambasada Urody's offer includes the following procedures that may be applicable after individual qualification:
- Botulinum toxin can weaken the lateral part of the orbicularis oculi muscle and selected brow depressor muscles. It allows for a slight, temporary lifting of the tail of the brow, but it is not a method for correcting a genuinely lowered corner. Incorrect administration may exacerbate asymmetry or cause drooping of the brow or eyelid.
- Lifting threads, including barbed threads and Aptos, can reposition the tissues of the lateral part of the brow and temple. The effect depends on anatomy and the degree of laxity; the procedure does not replace surgical eyelid stabilization.
- HIFU, including Sonoqueen, microneedling radiofrequency, Pellevé RF, Zaffiro, Indiba, and selected Accent Prime protocols can improve tissue tension through controlled thermal action and collagen remodeling.
- Laser lifting, hybrid lifting, ClearLift 4D, Soft Lift, Max Deep IR, and fractional resurfacing can reduce laxity and fine wrinkles in the orbital area. Not every technology or handpiece can be used directly on the eyelids.
- Plasma eyelid lifting contracts superficial tissues and can reduce minor excess skin, but it does not correct the ligamentous apparatus.
- Tissue stimulators, polynucleotides, under-eye mesotherapy, PRP, HD PRP, I-PRF, CGF, collagen mesotherapy, microneedling, and Dermapen 4.0 primarily serve to improve skin quality. Their effect on the positioning of the corner is indirect.
- Hyaluronic acid or calcium hydroxyapatite can restore lost volume in the temporal area or midface, improving support for the tissues surrounding the eye. However, the orbital and temporal area belongs to high vascular risk zones, which is why the procedure should only be performed by an experienced physician with an excellent knowledge of facial anatomy, the properties of the product used, and the principles of prevention, diagnosis, and management of vascular complications. Calcium hydroxyapatite should not be injected directly into the delicate tissues of the eyelids or the tear trough.
A true change in the position of the lateral canthus is primarily made possible by canthopexy or canthoplasty, as these procedures act directly on the eyelid support apparatus, especially the lateral canthal tendon.
- Canthopexy involves suspending and stabilizing the existing structures of the lateral canthus without completely severing them. It is mainly used for mild to moderate lower eyelid laxity and when additional lower eyelid support is needed.
- Canthoplasty is a more extensive procedure. It involves surgical release, shortening, reconstruction, or re-anchoring of the lateral canthal tendon to the orbital periosteum in a precisely determined position. This allows changing the height of the lateral canthus, lower eyelid tension, and the shape of the palpebral fissure.
If the appearance of a drooping corner is primarily due to the descent of the lateral part of the brow, the appropriate approach may be a surgical brow lift. In the case of excess lax skin of the upper eyelid, blepharoplasty is considered instead. These procedures address different anatomical issues than canthopexy and canthoplasty, which is why they should not be used interchangeably. In some patients, a combination of several procedures may be necessary.
Every surgical procedure in the orbital area requires detailed oculoplastic or surgical qualification. Evaluations include lower eyelid tension, eyeball position, ocular surface condition, the presence of dry eye syndrome, eyelid muscle function, and the quality of bony support. Excessive or improperly directed correction can lead to asymmetry, an unnatural eye shape, incomplete eyelid closure, tearing, dryness and corneal damage, lower eyelid eversion (ectropion), or recurrence of the malpositioned lateral canthus.
