Difference Between Blepharochalasis and Dermatochalasis

Key Difference – Blepharochalasis vs Dermatochalasis

Blepharochalasis and dermatochalasis are benign eye conditions that are uncomplicated on most occasions. Blepharochalasis is characterized by the episodic inflammation of eyelids. In a majority of cases, bilateral upper eyelids are affected. On the other hand, dermatochalasis is the condition that we identify as “baggy eyes” in lay terms. The key difference between blepharochalasis and dermatochalasis is thateyelids are inflamed in blepharochalasis but not in dermatochalasis.

What is Blepharochalasis?

Blepharochalasis is characterized by the episodic inflammation of eyelids. In a majority of the cases, bilateral upper eyelids are affected. Usually, a patient gets 3-4 attacks per year.

Causes

• Familial angioneuroticedema
• Asher syndrome

Clinical Features

• Painless swelling of the eyelids
• Erythema
• Wrinkling of the skin and skin thinning
• Lacrimal gland and orbital fat prolapse
• Subcutaneous telangiectasia
• Ptosis

Management

Steroids and antihistamines are usually prescribed to counter the ongoing inflammatory processes during an attack. Surgical intervention may be necessary to correct complications such as ptosis and prolapse of the adjacent structures.

What is Dermatochalasis?

Dermatochalasis is the condition that we identify as “baggy eyes” in lay terms.

Causes of Dermatochalasis

• Advanced age
• Thyroiddiseases
• Xanthelasma
• Renal failure
• Amyloidosis
• Ehlers Dandlos syndrome
• Traumatic causes

眼部肌肉的松弛,extrac沉积ellular matrix substances and fluid accumulation are believed to be the causes of this condition.

In most occasions, dermatochalasis presents as a cosmetic problem, but occasionally the edematous and enlarged eyelids can interfere with the clarity of the person’s superior visual field. In rare circumstances, this can be complicated with dermatitis and blepharitis.

When dermatochalasis presents as a cosmetic problem, surgical treatment can be offered. It is important to properly identify any underlying pathological condition and treat it appropriately rather than attributing it to the advanced age in unusual presentations with other comorbidities.

What is the Similarity Between Blepharochalasis and Dermatochalasis?

• Swelling of the eyelids is the typical feature of both these conditions.

Blepharochalasis is characterized by the episodic inflammation of eyelids. In a majority of the cases, bilateral upper eyelids are affected. Dermatochalasis is the condition that we identify as “baggy eyes” in lay terms. Inflammation of the eyelids occurs only in blepharochalasis. This is the difference between blepharochalasis and dermatochalasis.
