Clinical UM Guideline

This document addresses blepharoplasty, blepharoptosis repair, and brow lift procedures. Blepharoplasty is a surgical procedure performed on the upper and/or lower eyelids in which redundant tissues (skin, muscle, or fat) are excised. Blepharoptosis occurs when the eyelid itself droops below its normal position. Brow lift surgery is designed to restore the eyebrow to its normal anatomic position. These procedures may be performed for both cosmetic and functional purposes. The treatment of functional superior visual field restriction generally requires either a blepharoplasty and/or blepharoptosis repair OR a brow lift procedure, depending upon the cause of the visual field loss. Those cases where combined procedures are requested must meet the individual criteria for each procedure.

Note: Conjunctival irritation or eye disease related to ectropion, entropion, metabolic disease, trauma or other conditions may require surgical intervention using a variety of ophthalmologic procedures. These conditions are not discussed in this document. The medical necessity of the surgical correction of these problems should be determined by considering the specific underlying medical and ophthalmologic issues.

Note: For cases where combined procedures (for example, blepharoplasty and brow lift) are requested, the individual must meet the criteria for each procedure.

Note: This document does not address gender affirming surgery or procedures. Criteria for gender affirming surgery or procedures are found in applicable guidelines used by the plan.

Medically Necessary: In this document, procedures are considered medically necessary if there is a significant functional impairment AND the procedure can be reasonably expected to improve the functional impairment.

Reconstructive: In this document, procedures are considered reconstructive when intended to address a significant variation from normal related to accidental injury, disease, trauma, treatment of a disease or congenital defect.
Note: Not all benefit contracts include benefits for reconstructive services as defined by this document. Benefit language supersedes this document.

Cosmetic: In this document, procedures are considered cosmetic when intended to change a physical appearance that would be considered within normal human anatomic variation. Cosmetic services are often described as those which are primarily intended to preserve or improve appearance.

Medically Necessary:

Blepharoplasty and repair of blepharoptosis have been accepted as common surgical procedures for the management of upper eyelid conditions. There is adequate evidence in the peer-reviewed medical literature to support the use of upper lid surgery for significantly impaired superior field of vision associated with functional impairment. Such procedures have been shown to improve the individual’s field of vision, quality of life, and activities of daily living such as driving and reading.

Blepharoplasty is performed to remove excess skin tissue from the upper lid. Blepharoptosis repair corrects weakness of the levator palpebrae muscle. This weakness results in the drooping of the upper lid with possible obstruction of the superior visual field if the abnormality is severe enough. Many cases of mild ptosis do not result in significant superior visual field compromise. Aging or (less commonly) disease may result in excess upper lid skin that overhangs the lashes and restricts the superior visual field. Blepharoplasty is most commonly performed for cosmetic reasons, but may be medically necessary if vision is impaired. There are many causes of ptosis and pseudoptosis: congenital disorders; muscle, nervous, and mechanical disorders; complications due to eye surgery; eyelid and brain tumors; and age-related changes that damage the musculature of the eyelid. Many common medical disorders have been associated with ptosis including diabetes, stroke, and myasthenia gravis. If congenital ptosis is untreated in children, amblyopia (lazy eye) may develop. Ptosis repair typically involves reconstructive procedures on the levator muscle and connective tissues of the eyelid.

A brow lift (repair of eyebrow ptosis), when performed to improve an individual’s appearance in the absence of any signs and/or symptoms of functional abnormalities, is considered cosmetic. In extreme cases, if a person has significant brow ptosis, a brow lift may be needed for functional reasons. Brow lift surgery works by strengthening the tissues that support the brow. Often this is accomplished with a forehead procedure, which results in a less visible scar than procedures performed on the brow itself. For some individuals, the midforehead is useful as the site of incision when deep forehead lines (furrows) are present to minimize scarring. Brow lifts may be performed as a separate procedure or in conjunction with blepharoplasty or blepharoptosis repair. In some instances, a functional brow lift may be the only procedure required to correct functional superior visual field loss.

Upper eyelid blepharoplasty or blepharoptosis repair may be done for the treatment of occlusion amblyopia, a condition that can develop in children when one eye is occluded by excess eyelid skin or a drooping eyelid. When such conditions are present and one eye is occluded, the brain may start favoring one eye more than the other. Over time, the brain relies more on the favored eye, which becomes stronger and the other eye weaker, leading to poor overall vision. Amblyopia most commonly develops on children under the age of 7 and there are several types. Occlusion amblyopia, also referred to as deprivation amblyopia, as noted above, occurs when one eye is occluded. On addition to occurring in a child due to excess eyelid skin or eyelid ptosis, it mor commonly occurs due to eyepatch therapy in a child being treated for strabismus (also known as strabismic amblyopia). Strabismic amblyopia may be treated with vision therapy, eyedrops and/or surgery of the weakened eye muscles. Amblyopia may also result from a difference in visual acuity between the eyes, which is known as refractive amblyopia. Refractive amblyopia is usually treated with corrective lenses.

Assessment of the degree of visual impairment due to either blepharoptosis or excess upper eyelid skin is critical in understanding the severity of functional impairment due to the condition. Two accepted standard methods for such measurement include visual field assessments and measurement of the margin reflex distance (MRD, also known as the mid-pupil to upper eyelid distance). Both tests evaluate the degree of visual field loss due to the intrusion of either the upper eyelid edge or excess eyelid skin into the visual field (Meyer, 1989; Meyer, 1993). Visual field assessment may be performed manually or via computerized analysis devices to evaluate and map an individual’s peripheral field of vision for each eye. Measurement of the MRD is a method that has been validated in research studies to correlate well with the results of visual field tests (Boboridis, 2001; Meyer, 1998; Rebowe, 2020). MRD is calculated by measuring the distance between the corneal light reflex (the central visual access) and the edge of either the upper eyelid or upper eyelid skin, whichever is closest. An MRD measurement of 1-2 mm is generally considered to be associated with significant visual impairment indicating a good candidate for repair (Rebowe, 2020; Small, 1998).

In 2011, Cahill and colleagues published a report from the American Academy of Ophthalmology (AAO) on the functional indications for upper eyelid surgery. The literature search strategy identified a small number of relevant case series meeting the inclusion criteria (n=13). These studies evaluated a wide variety of surgical approaches to ptosis. One study utilized subjects with “simulated ptosis,” created with special contact lenses, while the remaining studies involved subjects with ptosis. The authors discuss additional studies in the discussion section, which were explicitly excluded from the literature search. These studies are included to demonstrate the effect of ptosis on superior peripheral field of vision and are the basis of the visual field loss recommendation. These studies all utilized different perimetric techniques to evaluate visual field loss. The impact of ptosis on down-gaze is addressed in the discussion section as well. The authors address several small studies not included in the initial literature abstraction. These studies demonstrate the effect of visual field impairment and low MRD₁ measurements impact on down-gaze. However, the result of one small study (n=34) demonstrates how ptosis repair impacts down-gaze impairment. The report concludes by providing guidelines for “indicating when surgical intervention is expected to provide functionally significant improvement.” However, it must be noted that these recommendations are based on a limited number of poor quality studies with small numbers of participants. The authors note that these studies are only Level III evidence. Additionally, the studies included in the review are primarily regarding the impact of surgical correction of ptosis, rather than on the identification of functional impairment. The data used in this report is limited to case reports, the majority of which have methodological issues, and the body of evidence is insufficient to allow conclusions to be drawn regarding selection criteria for upper eyelid ptosis and blepharoplasty.

In 2019, Hollander and colleagues conducted a large systematic review on the functional outcomes of upper eyelid blepharoplasty. The researchers reviewed 3525 studies and included 28 in the final review. Outcomes included dry eyes, upper visual field, eyebrow height, shape of cornea, sensitivity of upper eyelid skin, contrast sensitivity, eyelid kinematics and quality of life. The authors concluded that upper blepharoplasty has many beneficial functional outcomes including increased visual field, improvement in headaches and improvement in overall quality of life. The review’s design was limited by inclusion of studies with mostly female participants (several 80-100% female), compromising generalizability of the results, and the lack of standardization in surgical techniques chosen for inclusion.

Amblyopia: A type of poor vision that is characterized by one eye being stronger than the other. This condition is due to the brain favoring one eye more than the other. Over time the brain relies more on the favored eye, which becomes the stronger eye and the other eye weaker. The cause of amblyopia may be congenital or due to environmental factors and most frequently occurs in children.

Anophthalmia: Absence of all eye tissue; may be present at birth.

Blepharitis: Inflammation of the eyelids.

Blepharoplasty: Surgical procedures on the upper or lower eyelids commonly done for cosmetic reasons or to correct functional problems.

Blepharospasm: Involuntary spasmodic contraction of the orbicularis oculi muscle; may occur in isolation or be associated with other dystonic contractions of facial, jaw, or neck muscles; usually initiated or aggravated by emotion, fatigue, or drugs.

Central vision: Straight-ahead vision, where light and image is focused on the macula and fovea centralis area of the retina, as distinguished from side or peripheral vision; the part of the vision that is essential for driving, reading, and other activities that require detailed, straight-ahead vision.

Dermatochalasis: The presence of redundant eyelid skin, almost always progressive with aging.

Ectropion: Outward turning or eversion of the eyelid.

Entropion: Inward turning or inversion of the eyelid.

Epiphora: Chronic and excessive tearing.

Occlusion amblyopia (also referred to as deprivation amblyopia): The development of amblyopia in a child who has occlusion of one eye. In most cases, this occurs in previously stronger eye in a child undergoing patch therapy for strabismus, but may also occur in individuals with other types of eye occlusion, such as excess eyelid skin or eyelid ptosis.

Pseudoptosis: A condition mimicking true ptosis; does not require surgical intervention.

Ptosis: Drooping of the upper eyelid; may be caused by levator dysfunction or neurologic diseases.

Trichiasis: A lid deformity resulting in the misdirection of eyelashes toward the eye.
