If enophthalmos occurs after trauma or surgery, cosmetic improvement can be achieved through keratopigmentation (corneal tattooing) and retrobulbar (behind the eye) filler injection.

What is Enophthalmos? Enophthalmos is a condition where the eyeball retracts into the eye socket (orbit). This backward displacement gives the eye a sunken appearance compared to its normal position. Enophthalmos can be mild and unnoticeable or severe enough to cause facial asymmetry and visual impairments.

Causes of Enophthalmos The causes of enophthalmos can vary and may include:

Orbital Trauma:

• Blowout Fractures: Trauma, such as a blow to the eye socket, can cause fractures in the orbital bones. When the thin bones that form the orbital floor or medial wall break, orbital contents may herniate into the adjacent sinuses, leading to enophthalmos.
• Retrobulbar Hemorrhage: Bleeding behind the eyeball reduces the volume of orbital contents, causing the eye to sink.

Fat Atrophy:

• Aging: As people age, there is a natural loss of orbital fat, which can cause the eye to appear more sunken. This process is usually slow.
• Systemic Diseases: Some systemic conditions, like scleroderma or other connective tissue disorders, can cause orbital fat atrophy, leading to enophthalmos.
• Involutional Changes: Involutional enophthalmos is associated with the natural aging process and the loss of fat or muscle tissue around the eye.

Scarring or Fibrosis:

• Post-Surgical Changes: After surgeries involving the removal of tissues in the orbital region or the treatment of tumors, fibrosis and scar tissue formation can cause the eye to retract.
• Inflammatory Conditions: Chronic inflammation within the orbit, such as orbital pseudotumor or thyroid eye disease, can lead to fibrosis and subsequent enophthalmos.

Silent Sinus Syndrome: This rare condition involves the gradual collapse of the maxillary sinus, causing the orbital floor to drop and the eye to sink. Silent sinus syndrome is usually painless and progresses slowly, often diagnosed when patients notice facial asymmetry.

Oncological Causes:

• Orbital Tumors: Tumors within the orbit can displace the eyeball. Depending on the tumor’s location, the eye may be pushed forward (proptosis) or enophthalmos may occur if bone or fat erosion happens.

Congenital Causes: Some individuals may be born with enophthalmos due to underdevelopment of the orbit or surrounding structures.

Symptoms of Enophthalmos Patients with enophthalmos may present with the following symptoms:

• Sunken Eye Appearance: The most noticeable symptom is the sunken appearance of the eye in the orbit, which can cause facial asymmetry.
• Double Vision (Diplopia): Depending on the cause and severity, the displacement of the eye may affect the visual axis and result in double vision.
• Visual Impairments: In severe cases, there may be narrowing of the visual field or blurred vision.
• Reduced Eye Movement: In cases where scarring or fibrosis is involved, the eye may not move freely within the orbit.

Diagnosis Diagnosing enophthalmos typically involves:

• Physical Examination: A comprehensive eye exam that includes measurements of eye position relative to the orbit.
• Imaging Studies: CT (Computed Tomography) or MRI (Magnetic Resonance Imaging) scans are often used to evaluate orbital bone structures and identify underlying conditions such as fractures, tumors, or sinus problems.
• Visual Function Tests: Assessments for double vision and visual field defects to evaluate the impact of enophthalmos on vision.

Treatment of Enophthalmos The treatment of enophthalmos depends on the underlying cause and severity of the condition:

Surgical Intervention:

• Orbital Reconstruction: In cases of traumatic enophthalmos, surgical repair may be necessary, using implants to restore the orbital floor or walls.
• Fat Injection or Orbital Implants: To correct volume loss, fat injections or the placement of orbital implants may be used.
• Endoscopic Sinus Surgery: For conditions like silent sinus syndrome, surgery may be performed to restore normal sinus anatomy.

Non-Surgical Management:

• Observation: In mild cases or when the condition is stable and not causing significant symptoms, observation may be sufficient.
• Managing Underlying Conditions: Treating the underlying cause, such as controlling inflammation in thyroid eye disease, can sometimes improve enophthalmos.

Cosmetic Correction:

When enophthalmos is a cosmetic concern, various surgical and non-surgical options can be considered to improve facial symmetry and appearance.

Prognosis The prognosis of enophthalmos largely depends on its cause and the success of treatment. In cases of trauma or silent sinus syndrome, surgical correction can often restore the eye to its normal or near-normal position. However, in cases involving significant scarring or fat atrophy, complete correction may be more difficult, and the focus will be on improving both appearance and function as much as possible.

Enophthalmos can affect not only facial aesthetics but also have significant functional consequences. Early diagnosis and appropriate management are key to achieving the best outcomes.
