blepharochalasis

Blepharochalasis, also known as blepharochalasis syndrome, is a rare condition characterized by recurring episodes of inflammation and swelling in the eyelids. This condition was first described by Beer in 1817, but the term "blepharochalasis" was assigned to it by Fuchs in 1896 [1][2].

The symptoms of blepharochalasis typically include:

• Recurring episodes of painless edema (swelling) in one or both eyelids
• Episodes can be unilateral or bilateral, and may affect the upper or lower eyelid
• The swelling is usually not painful and does not cause any vision problems [10]
• Over time, the repeated inflammation can lead to atrophy (shrinking) of the skin on the eyelid, resulting in a stretching and subsequent loss of elasticity [3][4]

Blepharochalasis is considered an idiopathic condition, meaning that its exact cause remains unknown. However, evidence suggests that it may be related to an immunopathogenic mechanism [2].

It's worth noting that blepharochalasis should not be confused with dermatochalasis, which refers to the redundancy and laxity of the eyelid skin and muscle, sometimes referred to as "baggy eyes" [7]. While both conditions affect the appearance of the eyelids, they are distinct entities with different underlying causes.

Blepharochalasis, a rare condition characterized by episodic inflammation of the eyelids, presents with several distinct signs and symptoms.

Common Signs and Symptoms:

• Episodic, painless eyelid swelling [1]
• Erythema (redness) may be present
• Flares typically last 2 to 3 days and may occur several times a year [1]
• The frequency of attacks usually dwindles as the patient ages, with the peak of disease activity occurring in the teenage years [1]

Additional Signs:

• Thin and wrinkled skin - repeated edema attacks can leave eyelid skin stretched and resembling wrinkled parchment paper [3]
• Bagginess - eyelid skin gradually loses its shape and effectiveness (atrophy), resulting in redundant skin folds [3]
• Subcutaneous telangiectasia (dilated blood vessels just beneath the skin) [7, 14]

Other Characteristics:

• The condition typically affects only the upper eyelids, and may be unilateral as well as bilateral [4]
• Recurrent episodes of eyelid edema can be observed with spontaneous resolution [4]
• Cigarette paper skin - a characteristic thinning or fine wrinkling of the involved skin [5]

Important Distinguishing Features:

• Absence of subcutaneous telangiectasia, episodic edema, and cigarette paper skin in dermatochalasis [7, 14]

Diagnostic Tests for Blepharochalasis

Blepharochalasis, a rare inflammatory syndrome affecting the eyelids, does not have specific diagnostic laboratory tests available. However, various tests and examinations can help rule out other conditions and aid in its diagnosis.

• Clinical examination: A thorough eye exam by an eye care specialist is crucial for diagnosing blepharochalasis. They will examine the eyelids and eyes, including the inside of them.
• Blood tests: Blood tests may be conducted to rule out infections or other conditions that cause swelling in the eyelids. However, these tests are usually normal in patients with blepharochalasis [10].
• Imaging studies: In some cases, imaging studies such as MRI or CT scans may be employed to rule out other conditions [12]. However, these tests are not typically used for diagnosing blepharochalasis.
• Patch testing: A detailed history and patch testing are the main diagnostic tools for blepharochalasis, particularly in cases where it presents in childhood or early adolescence [14].

Key points to note:

• Laboratory studies do not currently play a role in the diagnosis of blepharochalasis syndrome.
• Serum C1 inhibitor levels and activity may be checked to differentiate between blepharochalasis and hereditary angioedema, but these tests are usually normal in patients with blepharochalasis [2].
• Blood tests and imaging studies may be conducted largely to eliminate other conditions, as the results of supplementary tests in blepharochalasis are within the normal range [3].

Treatment Options for Blepharochalasis

Blepharochalasis, a rare condition characterized by recurrent episodes of idiopathic transient painless oedema in the adnexal tissue of the orbit, can be challenging to treat. While there is no established treatment protocol, various medications and surgical options have been explored.

Medical Treatment

• Steroids: Systemic or topical steroids have not been shown to play a significant role in acute attacks or the overall disease course [4]. However, some case reports suggest that oral doxycycline may be effective in treating flares [11].
• Antihistamines and anti-inflammatory medications: These medications do not appear to be effective in treating flares or changing the overall course of the disease [11].

Surgical Treatment

• Blepharoplasty: This surgical procedure can help alleviate or eliminate functional and cosmetic difficulties caused by edema attacks. It involves removing excess skin, muscle, and fat from the eyelids [14].
• Levator aponeurosis dehiscence repair: This surgical option is used to correct complications associated with blepharochalasis, such as droopy eyelids [3].

Other Treatment Options

• Oral doxycycline: Case reports suggest that oral doxycycline may be effective in treating flares of blepharochalasis [5, 11].
• Acetazolamide: A combination of acetazolamide and topical hydrocortisone has been reported to provide effective relief of periorbital oedema associated with blepharochalasis [6].

It is essential to note that treatment for blepharochalasis is often restricted, and the effectiveness of these options may vary from person to person. Consultation with an eye care specialist or a dermatologist can help determine the best course of treatment.

Blepharochalasis, a rare eyelid disorder, can be challenging to diagnose due to its similarity with other conditions. The differential diagnosis for blepharochalasis includes:

• Dermatochalasis: A condition characterized by excess skin on the upper and lower eyelids, often associated with aging.
  • According to [1], dermatochalasis is a result not of recurrent edema but rather an involutional aging change. This distinguishes it from blepharochalasis, which is characterized by subcutaneous telangiectasia, episodic edema, and cigarette paper skin.
