Blepharoplasty
Blepharoplasty refers to surgery to remove excess skin and fatty tissue around the eyes. Blepharochalasis is a term used to refer to loose or baggy skin (dermatochalasis) above the eyes, so that a fold of skin hangs down, often concealing the tarsal margin when the eye is open. Ptosis (also called blepharoptosis) is the term for drooping of one or both upper eyelids. This may occur in varying degrees from slight drooping to complete closure of the involved eyelid. In the most severe cases, the drooping can obstruct the visual field and cause positional head changes. Pathophysiology [edit]. Blepharochalasis results from recurrent bouts of painless eyelid swelling, each lasting for several days. This is thought to be a form of localized angioedema, or rapid accumulation of fluid in the tissues. Recurrent episodes lead to thin and atrophic skin Blepharochalasis can be bilateral (affecting both eyes) or unilateral (affecting only one eye). Blepharochalasis sufferers experience regular but unpredictable “attacks,” during which their eyelids become badly swollen. These attacks sometimes last as little as two hours, but the usual duration is about two days. Like blepharochalasis, dermatochalasis causes the appearance of baggy eyes, although it is generally less severe and the problem it presents is more cosmetic than functional. Most people with dermatochalasis simply learn to live with it, regarding it as just another sign of their advancing age. Problem. Blepharochalasis is a rare syndrome consisting of recurrent bouts of upper eyelid edema associated with thinning, stretching, and fine wrinkling of the involved skin. The lower eyelids are not commonly involved. These episodes often result in eyelid skin redundancy. In the early active phase, patients present with nonerythematous edema of one or both upper eyelids. Patients rarely (and only in severe cases) present with nonerythematous edema of the lower eyelids. Thinning of the eyelid skin may be present in the active stage of the disease. 1 A history of “dry eye” could matter. 2  If you’ve had problems with dry eye, from wearing contact lenses, taking certain medications, or some other reason, talk to your eye doctor about how it could impact LASIK. 3  You should be screened for dry eye before you have LASIK or other refractive surgery. LASIK is shorthand for laser-assisted in situ keratomileusis. Before you sign up for this surgery, here are a few things to think about: 1  LASIK is surgery to a very delicate part of your eye, and cannot be reversed. 2  As with any surgery, there are risks and possible complications. 3  Millions of people have had LASIK, many very successfully, but it’s not for everyone Blepharochalasis is a fairly rare condition that usually strikes children sometime around puberty, although cases involving adults are not unheard of. It was given its name in 1896 by influential ophthalmologist Dr. Ernst Fuchs, who took the name from the Greek words for eyelid (blepharo) and slackening (chalasis). Like blepharochalasis, dermatochalasis causes the appearance of baggy eyes, although it is generally less severe and the problem it presents is more cosmetic than functional. Most people with dermatochalasis simply learn to live with it, regarding it as just another sign of their advancing age.
