Laboratory Studies
In most cases of dermatochalasis, no laboratory work is necessary.
- In rare cases where hereditary angioedema is suspected, a C1-esterase inhibitor level should be performed.
- Similarly, if amyloidosis is suspected, then a protein electrophoresis is appropriate.
- If thyroid disease is suspected, thyroid-stimulating hormone serum (TSH) should be estimated.
Imaging Studies
In most cases, no imaging studies are necessary. If a patient is noted to have proptosis or enophthalmos, CT scan of the orbit is indicated.
Other Tests
Schirmer testing with topical anesthetic drops may be considered in patients who have significant dry eye symptoms and who desire blepharoplasty.[2] However, most ophthalmic plastic surgeons do not consider Schirmer tear testing to be the medical standard of care in evaluating blepharoplasty patients.[3]
Other tear function testing, including the Schirmer test I, Schirmer test II and the phenol red thread test may be indicated.
Procedures
Blepharoplasty is the procedure of choice for upper and/or lower eyelid dermatochalasis. This can be combined with fat removal in patients with steatoblepharon.
In patients noted to have ptosis of the upper eyelid, a concurrent ptosis surgery may be indicated. Similarly, patients with lower eyelid laxity or malposition may require corrective surgery.
Periocular fillers may be considered in patients with minor hollowing, steatoblepharon, or lid abnormalities. Several authors have also proposed the injection of periocular fillers in place of blepharoplasty for periorbital rejuvenation.[4]
Histologic Findings
In most cases of dermatochalasis, normal skin and muscle are identified. With dermatitis, a chronic nonspecific inflammatory infiltrate may be seen.
