What function does the pupil have?
Natural Folds
Muscles of the Eye Lid
Muscles
•
•
•
•
Riolan’s muscle
Levator
Muscle Muller
Orbicularis Oculi
The Eyelid
• 7 Layers of the eyelids
1. Skin-thinnest layer
2. Subcutaneous
connective tissue
3. Striated Muscle
4. Sub-muscular connective
tissue
5. Tarsal plate or fibrous layer
6. Smooth muscle
7. Conjunctiva
(Bulbar/Palpebral)
How are Hordoleum and Chalazions treated?
Lacrimal Pump
• Pump Action
– Lids
• Lateral/medial
• Muscles
• Disease
– Punctum
– Canniculli
• Lacrimal Sac
• Nasolacrimal Duct
• Facial Nerve Palsy (7th
CN)
Eyebrows and Eyelashes
• Eyebrows
– Thickened ridge of skin with short
hairs
– Diverts perspiration
• Eyelashes
– Also protects
– Sebaceous glands at base of each
lash are called Glands of Zeis
which produce a lubricating fluid
• Fluid can harden and clog the
gland, producing a stye or
painless chalazion. If painful
and infected it is called an
external hordeolum
Cataracts (myotonia) are caused by?
Functions of the Eye Lid
• Protection
– From debris
– light
• Pump – moisturize the
globe by spreading tears
across the eye
• Pushes excess tears and
bacteria from the surface
• Provides oil for the tear
film
What Are Droopy Lids
• Droopy lids occur when
the function of the eye
no longer meets it’s
normal required
function or position
• This can be unilateral or
bilateral
Causes of Droopy Lids
Over 425 cause of droopy
eyelids
• Aging
• Muscular
• Neurological
• Congenital
• Acquired
– Disease
– Trauma
Marcus Gunn
Rachel Schoffner, ESG, Memphis, TN
• Marcus Gunn phenomenon
(a.k.a. Marcus Gunn JawWinking[1][2] or Trigeminooculomotor Synkineses) is an
autosomal-dominant condition
with incomplete penetrance, in
which nursing infants will have
rhythmic upward jerking of their
upper eyelid. This condition is
characterized as a synkinesis:
when two or more muscles that
are independently innervated
have either simultaneous or
coordinated movements
Yamada K, Hunter DG, Andrews C, Engle EC (September 2005). "A novel KIF21A
mutation in a patient with congenital fibrosis of the extraocular muscles and Marcus
Gunn jaw-winking phenomenon
Facial Nerves
7th Cranial Nerve – Facial Nerve
Bells Palsy
Cranial Nerves
Ptosis
• Ptosis /ˈtoʊsɪs/ (from
Greek Ptosis or πτῶσις,
to "fall") is a drooping
or falling of the upper
or lower eyelid. The
drooping may be worse
after being awake
longer, when the
individual's muscles are
tired
Dermatochalasis
• Dermatochalasis is a
medical condition,
defined as an excess of
skin in the upper or
lower eyelid, also
known as "baggy
eyes."[1] It may be
either an acquired or a
congenital condition. It
is generally treated with
blepharoplasty.

Eyelid Crease
Medial/Canthal webbing
Inflammation/edema/infil
tration
• Herniated orbital fat pads
• Prolapsed lacrimal gland
• Eyelid laxity
Why Does this Impact Vision?
• Interferes with the
passage of light to the
retina
• Decreases acuity
• Limits peripheral field
of vision
• Changes posture
• Causes fatigue
• Impacts self-esteem
• Changes lifestyle
Seeking Surgical Intervention

Why?
Lifestyle change

Before and After Surgery
Testing
• Insurance vs Cosmetic
• Visual field testing
