Disorders of the Lashes Flashcards
an acquired misdirection of the eyelashes
TRICHIASIS
method used for treating trichiasis is usually dictated by what?
PATTERN of the misdirected lashes and QUALITY of the posterior lamella of the involved eyelid.
3 Complications of Trichiasis
Mnemonic: PIC
Pannus (growth of fine blood vessels onto the clear corneal surface)
Inferior punctate epitheliopathy
Corneal Ulceration
4 Treatment of Trichiasis
Mnemonics: CASM
- Mechanical epilation
- Standard electrolysis or radiofrequency ablation
- Cryotherapy
- Argon laser treatment of trichiasis
removing misdirected lashes with forceps at the slit lamp
MECHANICAL EPILATION
eyelash regrowth with mechanical epilation can be expected how many weeks post epilation?
3-8weeks
used for definitive treatment of trichiasis
Radiofrequency Ablation
insulated needle
Radiofrequency ablation
recurrence rate is high
Radiofreq Ablation
2 complications of Radiofrequency ablation
ADJACENT normal lashes may be damaged and
scarring of the ADJACENT eyelid margin tissue can worsen the problem
requires only local infiltrative anesthesia
cryotherapy
double freeze-thaw technique
cryotherapy
4 Disadvantages of Cryotherapy
PLEN
Possible interference with goblet cell function (decrease mucin production in tear film)
Loss of skin pigmentation
Edema lasting several days
Notching of the eyelid margin
technique thats sensitive to hair color
Argon Laser Treatment
treatment useful when ONLY A FEW SCATTERED eyelashes require ablation
Argon Laser Treatment
extra row of eyelashes present in place of the orifices of the meibomian gland
DISTICHIASIS
non invasive management of distichiasis
lubricants and soft contact lenses
surgical management of distichiasis
mnemonic: CEE
Cryoepilation
Electrolysis
Eyelid splitting with removal of the follicles
lashes growing from ABNORMAL POSITION or aberrant lashes arising from meibomian gland orifices
metaplastic lashes
caused by ciatrizing conjunctivitis (ocular pemphigod, Stevens Johnson,, Chemical Burns
Metaplastic
2 other term for Phthiriasis palpebrum
phthiriasis ciliaris and ciliary phthiriasis
ECTOPARASITOSIS of the eyelashes due to an infestation with PTHIRUS PUBIS
phthiriasis palpebrum
also known as pubic louse or crab louse
phthirus pubis
Signs and Symptoms of Phthiriasis Palpebrum
Pain, Gritty and Burning Sensation and Pruritus of the eyelids (itchy eyes)
MAIN SYMPTOM of Phthiriasis palpebrum
PRUPRITUS OF THE EYeLIDS
Treatment of Pthiriasis Palpebrum
a) Mechanical removal with forceps
b) Trimming or plucking of eye lashes
c) Traumatic amputation
d) Cryotherapy
e) Argon laser photocoagulation
f) Manual removal of nits after treatment
g) Family members, sexual contacts, and close companions should be examined
a condition that causes people to lose the hair from their eyelashes or eyebrows
MADAROSIS
2 types of madarosis
Non- scarring and Scarring
Internal hair structures remain, so the hair loss may be reversible
non scarring
more damage, and the hair loss in the eyebrows or eyelashes may be permanent.
Scarring
condition that causes a white patch or patches to appear in a person’s hair
Poliosis
A person can develop poliosis because of genetic conditions, such as:
tuberous sclerosis
piebaldism
Waardenburg syndrome
(True or False) People can also develop poliosis due to the use of certain medications
TRUE
Side effect of Vogt-Koyanagi-Harada disease (VKH)
Poliosis
