Blepharochalasis syndrome

Patients with chronic forms of blepharochalasis often develop eyelid deformities characterized by blepharoptosis and prolapse of the orbital fat and lacrimal gland. Some individuals have an acquired form of blepharophimosis, secondary to the dehiscence of the canthal tendons. In this late stage of the condition, the tendons still adhere to the periosteum of the orbital rims and loss of fixation occurs at the distal attachment between the tendons and the eyelid tissues. This results in a horizontally shortened palpebral fissure and a rounded deformity of the lateral canthal angle. Surgery remains the primary treatment.
