Blepharochalasis

👁️ Blepharochalasis

🔍 Definition

Blepharochalasis is a rare, degenerative condition characterized by recurrent episodes of painless eyelid swelling, leading over time to thinning, wrinkling, and atrophy of the eyelid skin, especially the upper eyelid.

🧠 Think of it as a “relapsing eyelid edema” that leaves the skin stretched out and saggy.

🧬 Etiology (Causes)

Factor	Note
Idiopathic	Most common; exact cause unknown
Puberty-linked	Often begins in teenage years
Possible triggers	Allergic reactions, hormonal changes
May be related to localized angioedema	Similar pathogenesis suspected

---

👀 Clinical Features

Phase	Features
Early (Edematous)	Recurrent, painless, transient swelling of eyelids
Intermediate	Skin starts thinning and becomes discolored or translucent
Late (Atrophic)	Lax, redundant upper eyelid skin (may hang over lashes)
Ptosis	Due to stretching or disinsertion of levator aponeurosis
Asymmetry	One eyelid may be more affected than the other
No pain or itching	Helps distinguish from allergic causes

📌 Recurrent attacks typically last a few hours to days and may resolve spontaneously.

📸 Classic Appearance

• Wrinkled, "crepey" upper eyelid skin

• Overhanging skin that may interfere with vision (in late stages)

• "Baggy" eyelids in a young patient

🧪 Diagnosis

Test	Purpose
Clinical history & exam	Recurrent swelling episodes, characteristic skin changes
Rule out other causes	Allergy testing, thyroid studies if indicated
Imaging (rarely needed)	CT/MRI if mass or deeper pathology suspected

---

🧾 Differential Diagnosis

Condition	Key Difference
Dermatochalasis	Age-related excess eyelid skin (not episodic)
Allergic blepharitis	Itchy, red, often with crusting
Angioedema	Usually sudden, associated with triggers
Orbital cellulitis	Painful, red, and potentially sight-threatening

---

💊 Treatment

🔹 Medical Management

• Not very effective long-term, but may help during attacks:

  • Cold compresses

  • Short course corticosteroids (oral or topical, if severe)

  • Antihistamines if allergy suspected

🧠 Note: These may reduce swelling but won’t reverse atrophic changes.

---

🔹 Surgical Management (Definitive)

Procedure	Indication
Blepharoplasty	Remove excess, lax upper eyelid skin
Ptosis repair	If levator aponeurosis has stretched or detached
Delayed until attacks subside	To avoid recurrence after surgery

---

⚠️ Complications

• Visual obstruction from overhanging lid skin

• Cosmetic disfigurement

• Ptosis affecting vision

• Psychosocial impact (especially in young patients)

---

🧠 Mnemonic: “Blepharo-CHILL-asis”

Chronic, painless, lax eyelid swelling in the CHILL zone — no redness or pain, just loose skin over time.

Key finding	Thin, wrinkled upper lid skin (“crepe paper”)
Treatment	Supportive + blepharoplasty (for cosmesis/vision)
Distinguishing trait	No itching/pain, no acute inflammation
