Blepharochalasis syndrome.

Area of Science:

• Ophthalmology
• Plastic Surgery

Background:

• Chronic blepharochalasis can lead to significant eyelid deformities.
• These deformities include blepharoptosis, orbital fat prolapse, and lacrimal gland prolapse.

Purpose of the Study:

• To describe the late-stage eyelid deformities associated with chronic blepharochalasis, specifically acquired blepharophimosis.
• To detail the pathophysiological changes in canthal tendons leading to these deformities.

Main Methods:

• Clinical observation and description of characteristic eyelid deformities.
• Analysis of the anatomical changes in canthal tendon attachments and eyelid tissues.

Main Results:

• Patients develop blepharoptosis and prolapse of orbital fat and lacrimal gland.
• Acquired blepharophimosis results from canthal tendon dehiscence, with tendons adhering to the periosteum.
• This leads to a horizontally shortened palpebral fissure and rounded lateral canthal angle.

Conclusions:

• Late-stage blepharochalasis presents with complex eyelid deformities.
• Surgical intervention is the primary treatment for these acquired deformities.
